[First Embodiment]
(Coaxial cable connection member 10)
FIG. 1 is a diagram illustrating an example of a coaxial cable connecting member 10 according to the first embodiment. 1A is a front view, FIG. 1B is a plan view, FIG. 1C is a side view, and FIG. 1D is a perspective view.
In the front view of FIG. 1A, the left-right direction of the paper surface is the left-right direction, and is denoted as the left side and the right side. In addition, the vertical direction of the paper is the vertical direction, and is expressed as an upper side and a lower side. Further, in the plan view of FIG. 1B, the vertical direction of the paper surface is the front-rear direction, and is represented as the front side and the rear side.
　同軸ケーブル接続部材１０の構成を、図１（ｄ）の斜視図に基づいて説明する。
　同軸ケーブル接続部材１０は、点線で囲って示されている本体部１１と、本体部１１から張り出した張出部１７とを備えている。
　本体部１１は、正面中央部に、同軸ケーブル３０（後述する図３参照）が挿入される貫通孔１２を備えている。貫通孔１２は、本体部１１を前後方向に貫通している（図１（ｃ）参照）。
　また、貫通孔１２の左右方向の外側には、回路基板２０の切欠き部２４（後述する図２参照）が挿入される挿入溝部１３を備えている。挿入溝部１３は、貫通孔１２を挟むように、左右方向の２か所に挿入溝１３Ｃを備えている。挿入溝部１３は、下側の挿入溝部張出１３Ａと上側の挿入溝部張出１３Ｂとを備え、挿入溝部張出１３Ａと挿入溝部張出１３Ｂとの間が挿入溝１３Ｃになっている。一例として、挿入溝部１３の挿入溝部張出１３Ａの左右方向の張り出し量は、挿入溝部張出１３Ｂの左右方向の張り出し量より大きい。
　なお、両側面に設けられた２か所の挿入溝１３Ｃは、左右方向で対称である。よって、一方の挿入溝部張出１３Ａ、挿入溝部張出１３Ｂ、挿入溝１３Ｃにのみ符号を付している。以下同様である。
　本体部１１が、同軸ケーブル３０を保持する保持部の一例であり、挿入溝１３Ｃが挿入部の一例である。
　そして、挿入溝部張出１３Ａと挿入溝部張出１３Ｂのいずれか一方又は両方が、回路基板２０の一方の表面（以下では表面と表記する。）又は他方の表面（以下では裏面と表記する。）の一方、乃至、両方に対して、同軸ケーブル３０の長手方向において面で接触する接触部である。 The configuration of the coaxial cable connecting member 10 will be described based on the perspective view of FIG.
The coaxial cable connecting member 10 includes a main body portion 11 surrounded by a dotted line and an overhang portion 17 that protrudes from the main body portion 11.
The main body 11 includes a through hole 12 into which a coaxial cable 30 (see FIG. 3 to be described later) is inserted at the front center. The through-hole 12 penetrates the main body portion 11 in the front-rear direction (see FIG. 1C).
Further, an insertion groove portion 13 into which a notch portion 24 (see FIG. 2 described later) of the circuit board 20 is inserted is provided outside the through hole 12 in the left-right direction. The insertion groove portion 13 includes insertion grooves 13C at two positions in the left-right direction so as to sandwich the through hole 12. The insertion groove 13 includes a lower insertion groove overhang 13A and an upper insertion groove overhang 13B, and an insertion groove 13C is formed between the insertion groove overhang 13A and the insertion groove overhang 13B. As an example, the lateral extension amount of the insertion groove portion overhang 13A of the insertion groove portion 13 is larger than the lateral extension amount of the insertion groove portion overhang 13B.
Note that the two insertion grooves 13C provided on both side surfaces are symmetrical in the left-right direction. Therefore, only one insertion groove overhang 13A, the insertion groove overhang 13B, and the insertion groove 13C are denoted by reference numerals. The same applies hereinafter.
The main body portion 11 is an example of a holding portion that holds the coaxial cable 30, and the insertion groove 13C is an example of an insertion portion.
One or both of the insertion groove overhang 13A and the insertion groove overhang 13B is one surface (hereinafter referred to as a front surface) or the other surface (hereinafter referred to as a back surface) of the circuit board 20. It is a contact part which contacts the surface in the longitudinal direction of the coaxial cable 30 with respect to one or both of these.
　また、本体部１１は、貫通孔１２の上側にはんだを供給するための開口１５を有する開口部１４を備えている。開口１５は、前側の端部に至るが、後側の端部には達していない（図１（ｂ）参照）。ここでは、開口１５は、表面形状を一方が開いたＵ字状としたが、閉じた円形であってもよく、他の形状であってもよい。また、はんだの供給が貫通孔１２の入り口から行える場合には、開口１５を備えなくてもよい。 Moreover, the main body 11 includes an opening 14 having an opening 15 for supplying solder to the upper side of the through hole 12. The opening 15 reaches the front end, but does not reach the rear end (see FIG. 1B). Here, the opening 15 has a U shape with one open surface, but may be a closed circle or another shape. Further, when the solder can be supplied from the entrance of the through hole 12, the opening 15 may not be provided.
　さらに、同軸ケーブル接続部材１０の上側の左側及び右側は、下側に向かって斜めになった傾斜面部１６となっている（図１（ａ）参照）。貫通孔１２を取り巻く肉厚の変動が少なくなるとともに、同軸ケーブル接続部材１０の熱容量が小さくなっている。
　これにより、同軸ケーブル接続部材１０と同軸ケーブル３０の露出させた外部導体３３とのはんだ付けが容易にできるようになっている。これについては、後述する。 Furthermore, the upper left side and the right side of the coaxial cable connecting member 10 are inclined surface portions 16 that are inclined downward (see FIG. 1A). The variation in the thickness surrounding the through hole 12 is reduced, and the heat capacity of the coaxial cable connecting member 10 is reduced.
As a result, the coaxial cable connecting member 10 and the exposed outer conductor 33 of the coaxial cable 30 can be easily soldered. This will be described later.
　さらに、貫通孔１２は、同軸ケーブル接続部材１０の後側に近い部分が、貫通孔１２の直径が徐々に後側に向かって広がるテーパ状のテーパ面１２Ａとなっている（図１（ｃ）参照）。テーパ面１２Ａは、同軸ケーブル３０の挿入を容易にするために設けられている（後述する図６参照）。 Further, in the through hole 12, a portion near the rear side of the coaxial cable connecting member 10 has a tapered surface 12A in which the diameter of the through hole 12 gradually increases toward the rear side (FIG. 1 (c)). reference). The tapered surface 12A is provided to facilitate the insertion of the coaxial cable 30 (see FIG. 6 described later).
　以上説明したように、同軸ケーブル接続部材１０の本体部１１は、貫通孔１２、挿入溝部１３、開口部１４、傾斜面部１６を備えている。以下では、貫通孔１２、挿入溝部１３、開口部１４、傾斜面部１６を説明する場合、「本体部１１」を表記しないことがある。 As described above, the main body portion 11 of the coaxial cable connecting member 10 includes the through hole 12, the insertion groove portion 13, the opening portion 14, and the inclined surface portion 16. Hereinafter, when the through-hole 12, the insertion groove portion 13, the opening portion 14, and the inclined surface portion 16 are described, the “main body portion 11” may not be described.
　そして、同軸ケーブル接続部材１０は、前側に張出部１７を備えている。そして、張出部１７の前側における左側の角及び右側の角が斜めになったコーナー面１７Ａになっている。すなわち、張出部１７の角は、鈍角になっている（図１（ｂ）参照）。
　後述するように、コーナー面１７Ａを設けて、張出部１７の角を鈍角にすることにより、同軸ケーブル接続部材１０に回路基板２０を挿入する際において、回路基板２０の基準導体２３の剥離を抑制する。
　なお、張出部１７を設けなくともよい。張出部１７を設けない場合には、本体部１１の挿入溝部１３を構成する挿入溝部張出１３Ａの前側の左側及び右側の角を斜めにしてコーナー面とすればよい。 The coaxial cable connecting member 10 includes an overhang portion 17 on the front side. Then, the left side corner and the right side corner on the front side of the overhanging portion 17 are corner surfaces 17A that are slanted. That is, the angle of the overhang portion 17 is an obtuse angle (see FIG. 1B).
As will be described later, when the circuit board 20 is inserted into the coaxial cable connecting member 10 by providing the corner surface 17A and making the angle of the overhanging portion 17 an obtuse angle, the reference conductor 23 of the circuit board 20 is peeled off. Suppress.
The overhanging portion 17 may not be provided. When the overhanging portion 17 is not provided, the left and right corners on the front side of the insertion groove overhang 13A constituting the insertion groove 13 of the main body 11 may be inclined to form a corner surface.
　同軸ケーブル接続部材１０の本体部１１（図１（ｄ）参照）の貫通孔１２に沿った長さがＭ（長さＭ）、張出部１７の本体部１１（図１（ｄ）参照）から張り出した長さがＮ（長さＮ）である。
　貫通孔１２は、テーパ面１２Ａを除く部分の直径がＨ（内径Ｈ）である。挿入溝部１３の挿入溝１３Ｃは、上下方向の高さがＧ（高さＧ）、両側の挿入溝１３Ｃ間の間隔がＷ（間隔Ｗ）である。
　ここでは、両側の挿入溝１３Ｃ間の間隔Ｗは、前後方向において一定であるとしている。しかし、前側と後側とで間隔が異なっていてもよい。また、挿入溝１３Ｃが斜めに設けられていてもよい。後述するように、同軸ケーブル接続部材１０の挿入溝部１３が回路基板２０の切欠き部２４と嵌合すればよい（後述する図５参照）。 The length along the through hole 12 of the main body portion 11 (see FIG. 1D) of the coaxial cable connecting member 10 is M (length M), and the main body portion 11 of the overhang portion 17 (see FIG. 1D). The length overhanging from N is N (length N).
The diameter of the portion of the through hole 12 excluding the tapered surface 12A is H (inner diameter H). The insertion groove 13C of the insertion groove portion 13 has a vertical height G (height G) and an interval between the insertion grooves 13C on both sides is W (interval W).
Here, the interval W between the insertion grooves 13C on both sides is assumed to be constant in the front-rear direction. However, the interval may be different between the front side and the rear side. Further, the insertion groove 13C may be provided obliquely. As will be described later, the insertion groove 13 of the coaxial cable connecting member 10 may be fitted into the notch 24 of the circuit board 20 (see FIG. 5 described later).
　同軸ケーブル接続部材１０は、一体に構成されている。よって、上記の本体部１１及び張出部１７は、連続している。なお、本体部１１の挿入溝部１３、開口部１４、傾斜面部１６及び張出部１７を区別するため、図１（ａ）、（ｂ）、（ｄ）において、一点鎖線で区切って示している。以下、同様である。 The coaxial cable connecting member 10 is integrally formed. Therefore, the main body portion 11 and the overhang portion 17 are continuous. In addition, in order to distinguish the insertion groove part 13, the opening part 14, the inclined surface part 16, and the overhang | projection part 17 of the main-body part 11, in FIG. 1 (a), (b), (d), it has shown and divided | segmented with the dashed-dotted line. . The same applies hereinafter.
　同軸ケーブル接続部材１０は、銅、真鍮、アルミニウム、亜鉛などの導電体材料で構成されている。同軸ケーブル接続部材１０は、導電体材料から削り出しにより製造できる。また、金型鋳造（ダイカスト）により製造することもできる。融点が低い亜鉛は、ダイカストによる同軸ケーブル接続部材１０の製造をより容易にする。
　なお、はんだ付けを容易にするため、同軸ケーブル接続部材１０の表面は、錫めっき、金めっき、銀めっき等のめっき処理されることが好ましい。 The coaxial cable connecting member 10 is made of a conductor material such as copper, brass, aluminum, or zinc. The coaxial cable connecting member 10 can be manufactured by cutting out from a conductive material. It can also be manufactured by die casting (die casting). Zinc having a low melting point makes it easier to manufacture the coaxial cable connecting member 10 by die casting.
In order to facilitate soldering, the surface of the coaxial cable connecting member 10 is preferably subjected to a plating treatment such as tin plating, gold plating, or silver plating.
（回路基板２０）
　図２は、同軸ケーブル接続部材１０に取り付けられる回路基板２０の一例を説明する図である。図２（ａ）は、表面図、図２（ｂ）は、図２（ａ）、（ｃ）のＩＩＢ－ＩＩＢ線での断面図、図２（ｃ）は、裏面図である。
　図２（ｂ）の断面図に示すように、回路基板２０は、誘電体板２１、誘電体板２１の表面（一方の表面）に設けられた信号が伝送される配線パタンである信号導体２２、誘電体板２１の裏面（他方の表面）に設けられた基準（接地、ＧＮＤ）電位が供給される基準（共通、接地、ＧＮＤ）導体２３を備えている。 (Circuit board 20)
FIG. 2 is a diagram illustrating an example of the circuit board 20 attached to the coaxial cable connecting member 10. 2A is a front view, FIG. 2B is a cross-sectional view taken along the line IIB-IIB in FIGS. 2A and 2C, and FIG. 2C is a rear view.
As shown in the cross-sectional view of FIG. 2B, the circuit board 20 includes a dielectric plate 21 and a signal conductor 22 that is a wiring pattern through which a signal provided on the surface (one surface) of the dielectric plate 21 is transmitted. A reference (common, ground, GND) conductor 23 to which a reference (ground, GND) potential is provided on the back surface (the other surface) of the dielectric plate 21 is provided.
　そして、信号導体２２の一方の端に対向するように（部分に）、切欠き部２４が設けられている。切欠き部２４は、例えば、コ字状に設けられている。ここでは、切欠き部２４の側面２４Ａ、２４Ｂ、２４Ｃの内、対向する側面２４Ａ、２４Ｃが平行になっている。切欠き部２４の側面２４Ａ、２４Ｃが、同軸ケーブル接続部材１０における挿入溝部１３の挿入溝１３Ｃに沿って挿入される。
　なお、前述したように、対向する側面２４Ａ、２４Ｃは、必ずしも平行でなくてもよい。 And the notch part 24 is provided so that it may oppose one end of the signal conductor 22 (part). The notch 24 is provided in a U shape, for example. Here, of the side surfaces 24A, 24B, and 24C of the notch 24, the opposing side surfaces 24A and 24C are parallel to each other. The side surfaces 24 </ b> A and 24 </ b> C of the notch 24 are inserted along the insertion groove 13 </ b> C of the insertion groove 13 in the coaxial cable connecting member 10.
As described above, the opposing side surfaces 24A and 24C do not necessarily have to be parallel.
　なお、信号導体２２及び基準導体２３は、誘電体板２１の縁から予め定められた距離離して設けられている。信号導体２２及び基準導体２３が誘電体板２１の縁まで延びていると、信号導体２２及び基準導体２３が誘電体板２１から剥離しやすいためである。なお、信号導体２２及び基準導体２３と誘電体板２１の縁との距離は、例えば０．５ｍｍである。 The signal conductor 22 and the reference conductor 23 are provided at a predetermined distance from the edge of the dielectric plate 21. This is because if the signal conductor 22 and the reference conductor 23 extend to the edge of the dielectric plate 21, the signal conductor 22 and the reference conductor 23 are easily separated from the dielectric plate 21. The distance between the signal conductor 22 and the reference conductor 23 and the edge of the dielectric plate 21 is, for example, 0.5 mm.
　また、後述する同軸ケーブル接続部材１０を用いない場合と異なり、回路基板２０は、内部導体挿入孔を備えていない（後述する図７（ａ）、（ｂ）及び図８（ｂ）参照）。すなわち、回路基板２０は、内部導体挿入孔を設けるなどの特殊な加工を要しない。
　切欠き部２４の幅をＳ（幅Ｓ）、切欠き部２４の深さをＵ（深さＵ）、誘電体板２１、信号導体２２、基準導体２３を合わせた厚さをＴ（厚さＴ）と表記する。 Unlike the case where the coaxial cable connecting member 10 described later is not used, the circuit board 20 does not include an internal conductor insertion hole (see FIGS. 7A, 7B, and 8B described later). That is, the circuit board 20 does not require special processing such as providing an internal conductor insertion hole.
The width of the notch 24 is S (width S), the depth of the notch 24 is U (depth U), and the combined thickness of the dielectric plate 21, signal conductor 22, and reference conductor 23 is T (thickness). T).
　誘電体板２１は、セラミック、ＰＴＦＥ（ポリテトラフルオロエチレン）、ＰＰ（ポリプロピレン）、ガラスエポキシなどの誘電体材料で構成されている。また、信号導体２２及び基準導体２３は、誘電体板２１の表面及び裏面に張り付けた銅箔などで構成されている。すなわち、回路基板２０は、プリント配線板（ＰＣＢ）であってもよい。 The dielectric plate 21 is made of a dielectric material such as ceramic, PTFE (polytetrafluoroethylene), PP (polypropylene), or glass epoxy. Further, the signal conductor 22 and the reference conductor 23 are made of a copper foil attached to the front and back surfaces of the dielectric plate 21. That is, the circuit board 20 may be a printed wiring board (PCB).
（同軸ケーブル３０）
　図３は、同軸ケーブル接続部材１０に取り付けられる同軸ケーブル３０の一例を示す図である。図３（ａ）は、側面図、図３（ｂ）は、図３（ａ）のＩＩＩＢ－ＩＩＩＢ線での断面図である。
　図３（ｂ）の断面図に示すように、同軸ケーブル３０は、内部導体３１、内部導体３１を取り巻く誘電体３２、誘電体３２を取り巻く外部導体３３、外部導体３３を取り巻く外部被覆３４を備えている。
　内部導体３１は、銅線などの導電体材料で構成されている。誘電体３２は、ＰＴＦＥ、ＰＥ（ポリエチレン）などの誘電体材料で構成されている。外部導体３３は、網組み銅線などの導電体材料で構成されている。なお、網組み銅線には、はんだ付けを容易にするように錫めっきが施されていてもよい。
　そして、外部被覆３４は、ビニルなどで構成されている。 (Coaxial cable 30)
FIG. 3 is a diagram illustrating an example of the coaxial cable 30 attached to the coaxial cable connecting member 10. 3A is a side view, and FIG. 3B is a cross-sectional view taken along line IIIB-IIIB in FIG. 3A.
As shown in the sectional view of FIG. 3B, the coaxial cable 30 includes an inner conductor 31, a dielectric 32 surrounding the inner conductor 31, an outer conductor 33 surrounding the dielectric 32, and an outer covering 34 surrounding the outer conductor 33. ing.
The inner conductor 31 is made of a conductor material such as a copper wire. The dielectric 32 is made of a dielectric material such as PTFE or PE (polyethylene). The outer conductor 33 is made of a conductive material such as a braided copper wire. The netted copper wire may be tin-plated so as to facilitate soldering.
The outer coating 34 is made of vinyl or the like.

（同軸ケーブル接続部材１０に同軸ケーブル３０を取り付ける方法）
　次に、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付ける方法を説明する。
　図６は、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付ける方法及び取り付けた状態を説明する図である。図６（ａ）は、同軸ケーブル接続部材１０と同軸ケーブル３０とを対向させた状態、図６（ｂ）は、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付けた状態を同軸ケーブル３０側から見た図、図６（ｃ）は同軸ケーブル接続部材１０に同軸ケーブル３０を取り付けた状態を回路基板２０側から見た図である。
　同軸ケーブル接続部材１０には、回路基板２０が既に取り付けられている。 (Method of attaching the coaxial cable 30 to the coaxial cable connecting member 10)
Next, a method for attaching the coaxial cable 30 to the coaxial cable connecting member 10 will be described.
FIG. 6 is a view for explaining a method of attaching the coaxial cable 30 to the coaxial cable connecting member 10 and the attached state. 6A shows a state in which the coaxial cable connecting member 10 and the coaxial cable 30 face each other, and FIG. 6B shows a state in which the coaxial cable 30 is attached to the coaxial cable connecting member 10 as viewed from the coaxial cable 30 side. FIG. 6C is a view of the state where the coaxial cable 30 is attached to the coaxial cable connecting member 10 as viewed from the circuit board 20 side.
The circuit board 20 is already attached to the coaxial cable connecting member 10.
　図６（ａ）に示すように、同軸ケーブル接続部材１０における貫通孔１２の回路基板２０側とは反対側に、同軸ケーブル３０を対向させる。このとき、同軸ケーブル３０には、内部導体３１が露出した領域Ｉと、外部導体３３を露出した領域ＩＩとが形成されている。 As shown in FIG. 6A, the coaxial cable 30 is opposed to the side of the through hole 12 in the coaxial cable connecting member 10 opposite to the circuit board 20 side. At this time, the coaxial cable 30 is formed with a region I where the inner conductor 31 is exposed and a region II where the outer conductor 33 is exposed.
　図６（ｂ）に示すように、同軸ケーブル３０は、同軸ケーブル接続部材１０の貫通孔１２のテーパ面１２Ａから、貫通孔１２に挿入される。そして、同軸ケーブル３０の内部導体３１を露出させた領域Ｉが、回路基板２０の信号導体２２上に配置される。このとき、図６（ｃ）に示すように、同軸ケーブル３０は、内部導体３１を露出させた領域Ｉと外部導体３３を露出させた領域ＩＩとの境界が、回路基板２０の切欠き部２４に突き当たるように挿入される。 As shown in FIG. 6B, the coaxial cable 30 is inserted into the through hole 12 from the tapered surface 12A of the through hole 12 of the coaxial cable connecting member 10. A region I where the inner conductor 31 of the coaxial cable 30 is exposed is disposed on the signal conductor 22 of the circuit board 20. At this time, as shown in FIG. 6C, in the coaxial cable 30, the boundary between the region I where the internal conductor 31 is exposed and the region II where the external conductor 33 is exposed is the notch 24 of the circuit board 20. It is inserted so that it may hit.
　そして、図６（ｂ）に示すように、同軸ケーブル３０の外部導体３３と同軸ケーブル接続部材１０とは、同軸ケーブル３０を挿入した側の貫通孔１２を囲む領域βにおいて、はんだ付けされる。次に、同軸ケーブル３０の内部導体３１と回路基板２０の信号導体２２とは、同軸ケーブル３０の内部導体３１が回路基板２０の信号導体２２上に配置された領域γにおいて、はんだ付けされる。さらに、同軸ケーブル接続部材１０の開口１５からはんだを供給して（流し込んで）、開口１５の近傍の領域δにおいて、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３とがはんだ付けされる。
　なお、貫通孔１２及び開口１５から供給されたはんだが、同軸ケーブル３０の露出させた外部導体３３に毛細管現象により侵入して、外部導体３３の全周にわたって同軸ケーブル接続部材１０とはんだ付けされることが好ましい。 6B, the outer conductor 33 of the coaxial cable 30 and the coaxial cable connecting member 10 are soldered in a region β surrounding the through hole 12 on the side where the coaxial cable 30 is inserted. Next, the inner conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20 are soldered in a region γ where the inner conductor 31 of the coaxial cable 30 is disposed on the signal conductor 22 of the circuit board 20. Further, solder is supplied (flowed in) from the opening 15 of the coaxial cable connecting member 10, and the coaxial cable connecting member 10 and the outer conductor 33 of the coaxial cable 30 are soldered in a region δ near the opening 15.
The solder supplied from the through hole 12 and the opening 15 enters the exposed external conductor 33 of the coaxial cable 30 by capillary action and is soldered to the coaxial cable connecting member 10 over the entire circumference of the external conductor 33. It is preferable.
　このようにして、同軸ケーブル３０の内部導体３１が回路基板２０の信号導体２２に接続され、同軸ケーブル接続部材１０を介して、同軸ケーブル３０の外部導体３３が回路基板２０の基準導体２３に接続される。
　なお、同軸ケーブル接続部材１０を用いて回路基板２０と同軸ケーブル３０とを接続する場合、同軸ケーブル接続部材１０の部分を接続部分と表記する。 In this way, the inner conductor 31 of the coaxial cable 30 is connected to the signal conductor 22 of the circuit board 20, and the outer conductor 33 of the coaxial cable 30 is connected to the reference conductor 23 of the circuit board 20 via the coaxial cable connecting member 10. Is done.
In addition, when connecting the circuit board 20 and the coaxial cable 30 using the coaxial cable connection member 10, the part of the coaxial cable connection member 10 is described as a connection part.
　ここで、同軸ケーブル接続部材１０を用いないで、回路基板２０に同軸ケーブル３０を接続する場合を説明する。
　図７は、同軸ケーブル接続部材１０を用いないで、回路基板２０に同軸ケーブル３０を接続する場合を説明する図である。図７（ａ）は、斜視図、図７（ｂ）は、側面図である。なお、図７（ｂ）の側面図では、接続部分（内部導体挿入孔２５の部分）を断面図で示している。 Here, the case where the coaxial cable 30 is connected to the circuit board 20 without using the coaxial cable connecting member 10 will be described.
FIG. 7 is a diagram illustrating a case where the coaxial cable 30 is connected to the circuit board 20 without using the coaxial cable connecting member 10. FIG. 7A is a perspective view, and FIG. 7B is a side view. In addition, in the side view of FIG.7 (b), the connection part (part of the internal conductor insertion hole 25) is shown with sectional drawing.
　図７（ａ）の斜視図及び図７（ｂ）の側面図に示すように、同軸ケーブル３０の露出させた内部導体３１は、回路基板２０に設けられた内部導体挿入孔２５を通過するように、回路基板２０の裏面側から表面側に折り曲げられている。そして、図７（ｂ）に示すように、同軸ケーブル３０の内部導体３１と回路基板２０の表面に設けられた信号導体２２とは、回路基板２０の表面側に突き出た内部導体３１の先端部分を含む領域εにおいて、はんだ付けされる。さらに、露出させた外部導体３３と回路基板２０の基準導体２３とは、同軸ケーブル３０の外部導体３３を露出させた領域ζにおいて、はんだ付けされる。
　なお、同軸ケーブル３０は、外部被覆３４が結束バンドなどの固定部材４０にて回路基板２０に固定されている。 As shown in the perspective view of FIG. 7A and the side view of FIG. 7B, the exposed inner conductor 31 of the coaxial cable 30 passes through the inner conductor insertion hole 25 provided in the circuit board 20. Further, the circuit board 20 is bent from the back surface side to the front surface side. As shown in FIG. 7B, the inner conductor 31 of the coaxial cable 30 and the signal conductor 22 provided on the surface of the circuit board 20 are the tip portions of the inner conductor 31 protruding to the surface side of the circuit board 20. In a region ε including soldering. Further, the exposed outer conductor 33 and the reference conductor 23 of the circuit board 20 are soldered in a region ζ where the outer conductor 33 of the coaxial cable 30 is exposed.
The coaxial cable 30 has an outer covering 34 fixed to the circuit board 20 by a fixing member 40 such as a binding band.
（信号伝送特性に及ぼす影響）
　図８は、同軸ケーブル接続部材１０を用いる場合と同軸ケーブル接続部材１０を用いない場合とで信号伝送特性に及ぼす影響を説明する断面図である。図８（ａ）は、同軸ケーブル接続部材１０を用いる場合、図８（ｂ）は、同軸ケーブル接続部材１０を用いない場合である。
　図８（ａ）に示すように、同軸ケーブル接続部材１０を用いる場合、同軸ケーブル３０は、同軸ケーブル接続部材１０の貫通孔１２を通過し、露出させた内部導体３１が同軸ケーブル接続部材１０から飛び出して、回路基板２０の信号導体２２上に載っている。このとき、露出させた内部導体３１は、折り曲げられることなく、真っ直ぐに延びている。 (Influence on signal transmission characteristics)
FIG. 8 is a cross-sectional view for explaining the influence on signal transmission characteristics when the coaxial cable connecting member 10 is used and when the coaxial cable connecting member 10 is not used. FIG. 8A shows a case where the coaxial cable connecting member 10 is used, and FIG. 8B shows a case where the coaxial cable connecting member 10 is not used.
As shown in FIG. 8A, when the coaxial cable connecting member 10 is used, the coaxial cable 30 passes through the through hole 12 of the coaxial cable connecting member 10, and the exposed internal conductor 31 is removed from the coaxial cable connecting member 10. It jumps out and rests on the signal conductor 22 of the circuit board 20. At this time, the exposed inner conductor 31 extends straight without being bent.
　そして、同軸ケーブル接続部材１０の挿入溝部張出１３Ａ及び張出部１７と回路基板２０の基準導体２３とは、領域αにおいて、はんだ付けされている。また、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３とは、領域β及び領域δにおいて、はんだ付けされている。そして、同軸ケーブル３０の内部導体３１と回路基板２０の信号導体２２とは、領域γにおいて、はんだ付けされている。 The insertion groove overhang 13A and overhang 17 of the coaxial cable connecting member 10 and the reference conductor 23 of the circuit board 20 are soldered in the region α. The coaxial cable connecting member 10 and the outer conductor 33 of the coaxial cable 30 are soldered in the region β and the region δ. The inner conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20 are soldered in the region γ.
　図２において説明したように、回路基板２０において、信号導体２２及び基準導体２３は、誘電体板２１の端から予め定められた距離を離して設けられている。したがって、切欠き部２４の側面２４Ｂ（図２（ａ）、（ｂ）参照）においても回路基板２０の信号導体２２と基準導体２３とは、回路基板２０の端から離れて設けられている。
　したがって、図８（ａ）に符号Ｐで示す部分（以下では、Ｐ部分と表記する。）では、回路基板２０の表面側及び裏面側に導体がない。
　しかし、同軸ケーブル接続部材１０は、基準導体２３に達するように回路基板２０側に張り出した張出部１７を備えている。そして、張出部１７は、回路基板２０の基準導体２３にはんだ付けされている。したがって、同軸ケーブル３０のＰ部分は、回路基板２０を挟んで基準電位が供給される張出部１７と対向することになる。すなわち、同軸ケーブル３０のＰ部分は、張出部１７とともに等価的にストリップライン（線路）を形成している。
　よって、同軸ケーブル接続部材１０を用いる場合、同軸ケーブル３０と回路基板２０との接続によって生じるインピーダンスの変動が抑制される。 As described in FIG. 2, in the circuit board 20, the signal conductor 22 and the reference conductor 23 are provided at a predetermined distance from the end of the dielectric plate 21. Therefore, the signal conductor 22 and the reference conductor 23 of the circuit board 20 are provided away from the end of the circuit board 20 also on the side surface 24B (see FIGS. 2A and 2B) of the notch 24.
Therefore, in the portion indicated by the symbol P in FIG. 8A (hereinafter referred to as the P portion), there is no conductor on the front surface side and the back surface side of the circuit board 20.
However, the coaxial cable connecting member 10 includes an overhanging portion 17 that protrudes toward the circuit board 20 so as to reach the reference conductor 23. The overhang portion 17 is soldered to the reference conductor 23 of the circuit board 20. Therefore, the P portion of the coaxial cable 30 faces the overhanging portion 17 to which the reference potential is supplied with the circuit board 20 interposed therebetween. That is, the P portion of the coaxial cable 30 forms a strip line (line) equivalently together with the overhanging portion 17.
Therefore, when the coaxial cable connecting member 10 is used, fluctuations in impedance caused by the connection between the coaxial cable 30 and the circuit board 20 are suppressed.
　また、同軸ケーブル接続部材１０を用いる場合、内部導体３１を折り曲げないので、取り付け作業が容易になり、取り付け作業におけるばらつきを生じない。 In addition, when the coaxial cable connecting member 10 is used, the inner conductor 31 is not bent, so that the mounting operation is facilitated and no variation occurs in the mounting operation.
　一方、図８（ｂ）に示す同軸ケーブル接続部材１０を用いない場合、露出した内部導体３１の符号Ｑで示す部分（以下では、Ｑ部分と表記する。）は、対向する基準導体２３が近くになく、また、内部導体３１を折り曲げていることで、電気力線が複雑な形状となるだけでなく、内部導体３１と基準導体２３との距離が一定でなくなる。さらに、内部導体３１は、回路基板２０を裏面側から表面側へ内部導体挿入孔２５を貫通している。よって、内部導体挿入孔２５を貫通する部分では、誘電体材料で構成された誘電体板２１の影響を受ける。
　よって、同軸ケーブル接続部材１０を用いない場合には、インピーダンスが変動する要因が多く存在する。 On the other hand, when the coaxial cable connecting member 10 shown in FIG. 8B is not used, the exposed reference portion 23 of the inner conductor 31 indicated by the symbol Q (hereinafter referred to as Q portion) is near. In addition, since the inner conductor 31 is bent, the electric lines of force are not only complicated, but the distance between the inner conductor 31 and the reference conductor 23 is not constant. Furthermore, the inner conductor 31 penetrates the inner conductor insertion hole 25 from the back surface side to the front surface side of the circuit board 20. Therefore, the portion penetrating the inner conductor insertion hole 25 is affected by the dielectric plate 21 made of a dielectric material.
Therefore, when the coaxial cable connecting member 10 is not used, there are many factors that cause the impedance to fluctuate.
　また、同軸ケーブル接続部材１０を用いない場合、取り付け作業に内部導体３１を折り曲げる工程を伴う。このとき、内部導体３１の曲がり具合は、折り曲げる工程毎に微妙な差を生じる。すなわち、曲げ具合などがばらつきやすい。このため、接続部分でのインピーダンスが折り曲げ工程毎に変動しやすい。 Further, when the coaxial cable connecting member 10 is not used, a process of bending the inner conductor 31 is involved in the mounting work. At this time, the bending condition of the inner conductor 31 causes a subtle difference for each bending process. That is, the bending condition is likely to vary. For this reason, the impedance at the connection portion is likely to fluctuate for each bending process.
　水滴等によるインピーダンスの変動を抑制するため、Ｑ部分にシリコーン樹脂などの誘電体材料を塗布してシーリングして、インピーダンスの変動を減らすことが行われる。しかし、シーリングの工程が増えるとともに、インピーダンスの変動を十分に抑制できない。
　また、同軸ケーブル３０を結束バンドなどの固定部材４０で回路基板２０に固定しても、同軸ケーブル３０は、微小な範囲において動いてしまう。
　これらは、信号伝送特性にばらつきを発生させる。 In order to suppress fluctuations in impedance due to water droplets or the like, a dielectric material such as silicone resin is applied to the Q portion and sealed to reduce fluctuations in impedance. However, as the number of sealing steps increases, impedance variation cannot be sufficiently suppressed.
Even if the coaxial cable 30 is fixed to the circuit board 20 with a fixing member 40 such as a binding band, the coaxial cable 30 moves in a minute range.
These cause variations in signal transmission characteristics.
　以上のように、同軸ケーブル接続部材１０を用いて回路基板２０と同軸ケーブル３０とを接続する場合の方が、同軸ケーブル接続部材１０を用いないで接続する場合に比べ、インピーダンスなど信号伝送特性に影響を与える要因が少ない。また、シーリングを必要としないため、取り付け作業が簡略化される。 As described above, when the circuit board 20 and the coaxial cable 30 are connected using the coaxial cable connecting member 10, the signal transmission characteristics such as impedance are improved compared to the case where the circuit board 20 is connected without using the coaxial cable connecting member 10. There are few influential factors. In addition, since no sealing is required, the installation work is simplified.
　次に、同軸ケーブル接続部材１０を用いる場合の取り付け方法における工程について説明する。
　前述したように、まず、同軸ケーブル接続部材１０に回路基板２０を取り付ける工程が行われる。ここでは、同軸ケーブル接続部材１０に回路基板２０が挿入される（図５（ａ）、（ｂ）参照）。このとき、図５（ｂ）に示したように、回路基板２０の裏面側を上にして（裏返して）、回路基板２０の基準導体２３と同軸ケーブル接続部材１０の挿入溝部張出１３Ａ及び張出部１７とが、領域αにおいて、はんだ付けされる。
　次に、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付ける工程が行われる。ここでは、回路基板２０の表面側を上にして（引っ繰り返して）、同軸ケーブル３０が挿入される（図６（ａ）参照）。そして、同軸ケーブル３０の外部導体３３と同軸ケーブル接続部材１０とが、領域βにおいて、はんだ付けされる。ついで、同軸ケーブル３０の予め露出させた内部導体３１と回路基板２０の信号導体２２とが、領域γにおいて、はんだ付けされる。さらに、同軸ケーブル接続部材１０の開口１５から、はんだを供給して、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３とが、領域δにおいて、はんだ付けされる（図６（ｂ）、（ｃ）参照）。 Next, the process in the attachment method when using the coaxial cable connecting member 10 will be described.
As described above, first, the process of attaching the circuit board 20 to the coaxial cable connecting member 10 is performed. Here, the circuit board 20 is inserted into the coaxial cable connecting member 10 (see FIGS. 5A and 5B). At this time, as shown in FIG. 5B, the back side of the circuit board 20 is turned up (turned over), and the reference conductor 23 of the circuit board 20 and the insertion groove extension 13A and the tension of the coaxial cable connecting member 10 are extended. The protruding portion 17 is soldered in the region α.
Next, the process of attaching the coaxial cable 30 to the coaxial cable connecting member 10 is performed. Here, the coaxial cable 30 is inserted with the front side of the circuit board 20 facing up (repeatedly) (see FIG. 6A). Then, the outer conductor 33 of the coaxial cable 30 and the coaxial cable connecting member 10 are soldered in the region β. Next, the previously exposed internal conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20 are soldered in the region γ. Furthermore, solder is supplied from the opening 15 of the coaxial cable connecting member 10, and the coaxial cable connecting member 10 and the outer conductor 33 of the coaxial cable 30 are soldered in the region δ (FIG. 6B, ( c)).
　ここでは、同軸ケーブル接続部材１０を回路基板２０に取り付ける際には、回路基板２０の裏面側を上にして（裏返して）、同軸ケーブル接続部材１０と回路基板２０とをはんだ付けする。次に、同軸ケーブル３０を取り付ける際には、回路基板２０の表面側を上にして（引っ繰り返して）、同軸ケーブル３０と同軸ケーブル接続部材１０及び回路基板２０とをはんだ付けする。
　すなわち、同軸ケーブル接続部材１０を用いると、取り付け工程において、回路基板２０を引っ繰り返す回数が１回ですむ。 Here, when the coaxial cable connecting member 10 is attached to the circuit board 20, the coaxial cable connecting member 10 and the circuit board 20 are soldered with the back side of the circuit board 20 facing up (turned over). Next, when the coaxial cable 30 is attached, the coaxial cable 30, the coaxial cable connecting member 10, and the circuit board 20 are soldered with the surface side of the circuit board 20 facing up (repeatedly).
That is, when the coaxial cable connecting member 10 is used, the circuit board 20 needs to be repeated once in the attachment process.
（信号伝送特性）
　次に、同軸ケーブル接続部材１０（実施例１と表記する。）を用いて、回路基板２０と同軸ケーブル３０とを接続した場合と、同軸ケーブル接続部材１０を用いない（比較例と表記する）で、回路基板２０と同軸ケーブル３０とを接続した場合とにおける信号伝送特性を説明する。 (Signal transmission characteristics)
Next, when the circuit board 20 and the coaxial cable 30 are connected using the coaxial cable connecting member 10 (denoted as Example 1), the coaxial cable connecting member 10 is not used (denoted as a comparative example). Now, signal transmission characteristics when the circuit board 20 and the coaxial cable 30 are connected will be described.
　実施例１の同軸ケーブル接続部材１０は、本体部１１の長さＭが５．０ｍｍ、張出部１７の長さＮが１．８ｍｍ、貫通孔１２の内径Ｈが３．８ｍｍ、挿入溝１３Ｃの高さＧが１．６ｍｍ、挿入溝１３Ｃ間の間隔Ｗが４．６ｍｍである。
　そして、回路基板２０の厚さＴが１．５ｍｍ、切欠き部２４の幅Ｓが４．８ｍｍ、切欠き部２４の深さＵが５．０ｍｍである。
　同軸ケーブル３０における外部導体３３の直径Ｄが３．６ｍｍである。
　すなわち、同軸ケーブル接続部材１０の挿入溝１３Ｃの高さＧは、回路基板２０の厚さＴより０．１ｍｍ大きい。また、挿入溝１３Ｃ間の間隔Ｗは、回路基板２０の切欠き部２４の幅Ｓより０．２ｍｍ小さい。さらに、貫通孔１２の内径Ｈは、同軸ケーブル３０の外部導体３３の直径Ｄより０．２ｍｍ大きい。これらのマージンにより、同軸ケーブル接続部材１０の挿入溝１３Ｃに回路基板２０が容易に挿入でき、同軸ケーブル接続部材１０の貫通孔１２に同軸ケーブル３０が容易に挿入できる。 In the coaxial cable connecting member 10 of the first embodiment, the length M of the main body 11 is 5.0 mm, the length N of the overhang 17 is 1.8 mm, the inner diameter H of the through hole 12 is 3.8 mm, and the insertion groove 13C.

The thickness T of the circuit board 20 is 1.5 mm, the width S of the notch 24 is 4.8 mm, and the depth U of the notch 24 is 5.0 mm.
The diameter D of the outer conductor 33 in the coaxial cable 30 is 3.6 mm.
That is, the height G of the insertion groove 13 </ b> C of the coaxial cable connecting member 10 is 0.1 mm larger than the thickness T of the circuit board 20. Further, the interval W between the insertion grooves 13 </ b> C is 0.2 mm smaller than the width S of the notch 24 of the circuit board 20. Further, the inner diameter H of the through hole 12 is 0.2 mm larger than the diameter D of the outer conductor 33 of the coaxial cable 30. With these margins, the circuit board 20 can be easily inserted into the insertion groove 13 </ b> C of the coaxial cable connecting member 10, and the coaxial cable 30 can be easily inserted into the through hole 12 of the coaxial cable connecting member 10.
　図９は、実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合と、同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）とにおける電圧定在波比（ＶＳＷＲ）を示す図である。横軸は周波数（ＧＨｚ）、縦軸はＶＳＷＲである。ＶＳＷＲは１．０に近いほど好ましい。
　ここでは、実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合と同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）とで、同じ伝送線路長となるように回路基板２０上に信号導体２２（伝送線路）を設定した。
　実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合では、図６（ｂ）、（ｃ）、図８（ａ）に示したように、回路基板２０の入力側及び出力側に、同軸ケーブル接続部材１０を用いて、同軸ケーブル３０を接続した。
　同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）では、図７（ａ）、（ｂ）及び図８（ｂ）に示したように、回路基板２０の入力側及び出力側に、同軸ケーブル接続部材１０を用いずに、同軸ケーブル３０を接続した。 FIG. 9 illustrates a case where the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of Example 1, and the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connection member 10. It is a figure which shows the voltage standing wave ratio (VSWR) in a case (comparative example). The horizontal axis is frequency (GHz), and the vertical axis is VSWR. The VSWR is preferably as close to 1.0 as possible.
Here, when the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of Example 1, and when the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connection member 10 ( In Comparative Example), the signal conductor 22 (transmission line) was set on the circuit board 20 so as to have the same transmission line length.
When the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of the first embodiment, as shown in FIGS. 6B, 6C, and 8A, the circuit board 20 The coaxial cable 30 was connected to the input side and the output side using the coaxial cable connecting member 10.
When the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connecting member 10 (comparative example), as shown in FIGS. 7A, 7B, and 8B, the circuit board is used. The coaxial cable 30 was connected to the input side and output side of 20 without using the coaxial cable connecting member 10.
　図９に示すＶＳＷＲには、変動が見られる。これは、伝送線路長が波長より大きく設定されているためである。しかし、測定した周波数範囲において、実施例１のＶＳＷＲは、比較例に比べて、ＶＳＷＲが全体に小さく抑えられている。
　実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合では、同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）に比べて、同軸ケーブル３０と回路基板２０との接続部分によって生じるインピーダンスの変動が抑制されているためと考えられる。 Variations are seen in the VSWR shown in FIG. This is because the transmission line length is set larger than the wavelength. However, in the measured frequency range, the VSWR of Example 1 is suppressed to be small as a whole as compared with the comparative example.
When the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of Example 1, the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connection member 10 (comparative example) This is considered to be because fluctuations in impedance caused by the connection portion between the coaxial cable 30 and the circuit board 20 are suppressed as compared with (1).
　図１０は、実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合と、同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）とにおける通過特性である。横軸は周波数（ＧＨｚ）、縦軸は、通過特性を表すＳパラメータのＳ２１（ｄＢ）である。Ｓ２１は大きいほど好ましい。
　図１０に示すように、２ＧＨｚ未満の低周波数側では、Ｓ２１は、実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合と同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）とで差が見られない。しかし、２ＧＨｚ以上の高周波数側では、Ｓ２１は、実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合の方が同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）に比べて大きくなっている。
　実施例１の同軸ケーブル接続部材１０を用いて同軸ケーブル３０と回路基板２０とを接続した場合では、同軸ケーブル接続部材１０を用いないで同軸ケーブル３０と回路基板２０とを接続した場合（比較例）に比べて、同軸ケーブル３０と回路基板２０との接続部分におけるインピーダンスの変動が少ないため反射が少なく、又、内部導体３１のみが露出される部分（マイクロストリップ線路を構成していない部分）が少ないため、外部に放射されるエネルギが少ないことによると考えられる。 FIG. 10 shows a case where the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of Example 1, and the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connection member 10. It is a passage characteristic in a case (comparative example). The horizontal axis represents frequency (GHz), and the vertical axis represents S parameter S21 (dB) representing the pass characteristic. S21 is so preferable that it is large.
As shown in FIG. 10, on the low frequency side of less than 2 GHz, S21 uses the coaxial cable connection member 10 and the case where the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of the first embodiment. However, no difference is seen when the coaxial cable 30 and the circuit board 20 are connected (comparative example). However, on the high frequency side of 2 GHz or higher, S21 is coaxial without using the coaxial cable connection member 10 when the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of the first embodiment. It is larger than when the cable 30 and the circuit board 20 are connected (comparative example).
When the coaxial cable 30 and the circuit board 20 are connected using the coaxial cable connection member 10 of Example 1, the coaxial cable 30 and the circuit board 20 are connected without using the coaxial cable connection member 10 (comparative example) ), There is less reflection at the connection portion between the coaxial cable 30 and the circuit board 20, so there is less reflection, and there is a portion where only the internal conductor 31 is exposed (portion that does not constitute a microstrip line). This is probably because the amount of energy radiated to the outside is small.
（通信回路及び通信装置）
　次に、同軸ケーブル接続部材１０を用いて回路基板２０と同軸ケーブル３０とを接続した通信回路及び通信回路を筐体に収納した通信装置について説明する。 (Communication circuit and communication device)
Next, a communication circuit in which the circuit board 20 and the coaxial cable 30 are connected using the coaxial cable connection member 10 and a communication device in which the communication circuit is housed in a casing will be described.
　図１１は、信号分配器１００を説明する図である。図１１（ａ）は、回路基板２０の表面側から見た図、図１１（ｂ）は、回路基板２０の裏面側から見た図である。なお、回路基板２０、同軸ケーブル３０及び同軸ケーブル接続部材１０が見えるように、筐体１１０を破線で示している。
　信号分配器１００は、通信装置の一例である。 FIG. 11 is a diagram for explaining the signal distributor 100. 11A is a diagram viewed from the front surface side of the circuit board 20, and FIG. 11B is a diagram viewed from the back surface side of the circuit board 20. In addition, the housing | casing 110 is shown with the broken line so that the circuit board 20, the coaxial cable 30, and the coaxial cable connection member 10 can be seen.
The signal distributor 100 is an example of a communication device.
　図１１（ａ）、（ｂ）に示した信号分配器１００は、回路基板２０、同軸ケーブル３０、同軸ケーブル接続部材１０を備えている。回路基板２０における誘電体板２１の表面には、一端がＩＮの同軸ケーブル３０に接続され、他の４つの端がＯＵＴ１～ＯＵＴ４の同軸ケーブル３０に接続された信号導体２２が設けられている。すなわち、信号導体２２は、５つの端部を有している。そして、回路基板２０における誘電体板２１の裏面には、基準導体２３が設けられている。誘電体板２１を挟んで設けられた基準導体２３と信号導体２２とでマイクロストリップラインを構成する。
　なお、信号導体２２は、ＩＮの同軸ケーブル３０に接続された端部から、ＯＵＴ１～ＯＵＴ４の同軸ケーブル３０に接続されたそれぞれの端部までの距離（伝送線路長）が同じになっている。
　そして、回路基板２０と同軸ケーブル３０とは、同軸ケーブル接続部材１０を介して接続されている。 A signal distributor 100 shown in FIGS. 11A and 11B includes a circuit board 20, a coaxial cable 30, and a coaxial cable connecting member 10. On the surface of the dielectric plate 21 in the circuit board 20, a signal conductor 22 having one end connected to the coaxial cable 30 of IN and the other four ends connected to the coaxial cable 30 of OUT1 to OUT4 is provided. That is, the signal conductor 22 has five ends. A reference conductor 23 is provided on the back surface of the dielectric plate 21 in the circuit board 20. The reference conductor 23 and the signal conductor 22 provided with the dielectric plate 21 in between constitute a microstrip line.
The signal conductor 22 has the same distance (transmission line length) from the end connected to the coaxial cable 30 of IN to each end connected to the coaxial cable 30 of OUT1 to OUT4.
The circuit board 20 and the coaxial cable 30 are connected via the coaxial cable connecting member 10.
　図１１（ａ）、（ｂ）に示した信号分配器１００は、ＩＮの同軸ケーブル３０に入力された信号を、ＯＵＴ１～ＯＵＴ４の同軸ケーブル３０に分配して出力する。なお、図１１（ａ）、（ｂ）に示す信号導体２２のパタンは、インピーダンス整合を考慮していない。 11 (a) and 11 (b), the signal distributor 100 distributes the signal input to the IN coaxial cable 30 to the coaxial cables 30 OUT1 to OUT4 and outputs them. In addition, the pattern of the signal conductor 22 shown to Fig.11 (a), (b) does not consider impedance matching.
　図１２は、移相器２００を説明する図である。図１２（ａ）は、回路基板２０の表面側から見た図、図１２（ｂ）は、回路基板２０の裏面側から見た図である。なお、回路基板２０、同軸ケーブル３０及び同軸ケーブル接続部材１０が見えるように、筐体２１０を破線で示している。
　移相器２００は、通信装置の他の一例である。 FIG. 12 is a diagram illustrating the phase shifter 200. 12A is a diagram viewed from the front surface side of the circuit board 20, and FIG. 12B is a diagram viewed from the back surface side of the circuit board 20. In addition, the housing | casing 210 is shown with the broken line so that the circuit board 20, the coaxial cable 30, and the coaxial cable connection member 10 can be seen.
The phase shifter 200 is another example of a communication device.
　図１２（ａ）、（ｂ）に示した移相器２００は、回路基板２０、同軸ケーブル３０、同軸ケーブル接続部材１０、アーム２２０を備えている。回路基板２０における誘電体板２１の表面には、ＩＮの同軸ケーブル３０に接続される信号導体２２Ａと、直径が異なる半円形の信号導体２２Ｂ、２２Ｃとが設けられている。回路基板２０における誘電体板２１の裏面には、基準導体２３が設けられている。誘電体板２１を挟んで設けられた基準導体２３と信号導体２２Ａ、２２Ｂ、２２Ｃとでマイクロストリップラインを構成する。
　そして、回路基板２０と同軸ケーブル３０とは、同軸ケーブル接続部材１０を介して接続されている。 A phase shifter 200 shown in FIGS. 12A and 12B includes a circuit board 20, a coaxial cable 30, a coaxial cable connecting member 10, and an arm 220. On the surface of the dielectric plate 21 of the circuit board 20, a signal conductor 22A connected to the coaxial cable 30 of IN and semicircular signal conductors 22B and 22C having different diameters are provided. A reference conductor 23 is provided on the back surface of the dielectric plate 21 in the circuit board 20. The reference conductor 23 and the signal conductors 22A, 22B, 22C provided with the dielectric plate 21 in between constitute a microstrip line.
The circuit board 20 and the coaxial cable 30 are connected via the coaxial cable connecting member 10.
　移相器２００は、ＩＮの同軸ケーブル３０に入力された信号を、位相を遅らせてＯＵＴ１～ＯＵＴ４の同軸ケーブル３０に出力する。すなわち、信号は、ＩＮの同軸ケーブル３０に接続された信号導体２２Ａから、アーム２２０を介して、信号導体２２Ｂ、２２Ｃに伝送される。このとき、信号が伝送される伝送線路の長さの違いによって位相差が生じ、位相差の異なる信号となって、信号導体２２Ｂ、２２Ｃに接続されたＯＵＴ１～ＯＵＴ４の同軸ケーブル３０から出力される。
　なお、図１２（ａ）、（ｂ）に示す信号導体２２（信号導体２２Ａ、２２Ｂ、２２Ｃ）のパタンは、インピーダンス整合を考慮していない。 The phase shifter 200 delays the phase of the signal input to the IN coaxial cable 30 and outputs it to the coaxial cables 30 OUT1 to OUT4. That is, the signal is transmitted from the signal conductor 22A connected to the IN coaxial cable 30 to the signal conductors 22B and 22C via the arm 220. At this time, a phase difference is generated due to a difference in length of the transmission line through which the signal is transmitted, and signals having different phase differences are output from the coaxial cables 30 of OUT1 to OUT4 connected to the signal conductors 22B and 22C. .
Note that the pattern of the signal conductor 22 ( signal conductors 22A, 22B, and 22C) shown in FIGS. 12A and 12B does not consider impedance matching.
　図１３は、アンテナ装置３００を説明する図である。図１３（ａ）は、回路基板２０の表面側から見た図、図１３（ｂ）は、回路基板２０の裏面側から見た図である。なお、回路基板２０、同軸ケーブル３０及び同軸ケーブル接続部材１０が見えるように、筐体（レドーム）３１０を破線で示している。
　アンテナ装置３００は、通信装置のさらに他の一例である。 FIG. 13 is a diagram illustrating the antenna device 300. FIG. 13A is a diagram viewed from the front surface side of the circuit board 20, and FIG. 13B is a diagram viewed from the back surface side of the circuit board 20. In addition, the housing | casing (radome) 310 is shown with the broken line so that the circuit board 20, the coaxial cable 30, and the coaxial cable connection member 10 can be seen.
The antenna device 300 is another example of a communication device.
　図１３（ａ）、（ｂ）に示したアンテナ装置３００は、回路基板２０、同軸ケーブル３０、同軸ケーブル接続部材１０を備えている。回路基板２０における誘電体板２１の表面には、ＩＮ／ＯＵＴの同軸ケーブル３０の内部導体３１に接続される信号導体２２が設けられている。回路基板２０における誘電体板２１の裏面には、基準導体２３が設けられている。誘電体板２１を挟んで設けられた基準導体２３と信号導体２２とでマイクロストリップラインを構成する。ここでは、回路基板２０における信号導体２２及び基準導体２３は、ダイポールアンテナを構成する。
　そして、回路基板２０と同軸ケーブル３０とは、同軸ケーブル接続部材１０を介して接続されている。 The antenna device 300 shown in FIGS. 13A and 13B includes a circuit board 20, a coaxial cable 30, and a coaxial cable connecting member 10. A signal conductor 22 connected to the inner conductor 31 of the coaxial cable 30 of IN / OUT is provided on the surface of the dielectric plate 21 in the circuit board 20. A reference conductor 23 is provided on the back surface of the dielectric plate 21 in the circuit board 20. The reference conductor 23 and the signal conductor 22 provided with the dielectric plate 21 in between constitute a microstrip line. Here, the signal conductor 22 and the reference conductor 23 on the circuit board 20 constitute a dipole antenna.
The circuit board 20 and the coaxial cable 30 are connected via the coaxial cable connecting member 10.
　アンテナ装置３００は、ＩＮ／ＯＵＴの同軸ケーブル３０に入力された信号に基づいて、電波を送信する。また、受信した電波に基づいて、ＩＮ／ＯＵＴの同軸ケーブル３０に信号を出力する。 The antenna device 300 transmits radio waves based on a signal input to the IN / OUT coaxial cable 30. In addition, a signal is output to the IN / OUT coaxial cable 30 based on the received radio wave.
　なお、図１３（ａ）、（ｂ）に示すアンテナ装置３００は、ダイポールアンテナを一つ備えているが、複数のダイポールアンテナを備えていてもよい。また、反射板を備えていてもよい。
　そして、アンテナ装置３００は、ダイポールアンテナと異なるアンテナを備えていてもよい。 Note that the antenna device 300 illustrated in FIGS. 13A and 13B includes one dipole antenna, but may include a plurality of dipole antennas. Moreover, you may provide the reflecting plate.
The antenna device 300 may include an antenna different from the dipole antenna.
　以上、通信回路及び通信装置を説明したが、回路基板２０と同軸ケーブル３０とを接続して使用するものであれば、上記以外の機能を有する通信回路及び通信装置であってもよい。 Although the communication circuit and the communication device have been described above, a communication circuit and a communication device having functions other than the above may be used as long as the circuit board 20 and the coaxial cable 30 are connected and used.
　なお、図１１、１２、１３に示した同軸ケーブル接続部材１０を用いて接続された回路基板２０及び同軸ケーブル３０が通信回路の一例である。 Note that the circuit board 20 and the coaxial cable 30 connected using the coaxial cable connecting member 10 shown in FIGS. 11, 12, and 13 are examples of communication circuits.
［第２の実施の形態］
　第１の実施の形態における同軸ケーブル接続部材１０は、上側の右側及び左側を傾斜面部１６とした。これは、開口１５の周囲の肉厚を薄くし、同軸ケーブル接続部材１０が均一に加熱されるようにするためである。つまり、開口１５からはんだを供給すると、同軸ケーブル接続部材１０の開口１５の周囲が均一に加熱されることで、はんだが毛細管現象により同軸ケーブル３０の外部導体３３に侵入し、外部導体３３が全周において、同軸ケーブル接続部材１０とはんだ付けされるようにしていた（図６（ｂ）、（ｃ）における領域δ）。
　第２の実施の形態では、同軸ケーブル接続部材１０の開口１５の周囲の形状を第１の実施の形態と異なる形状にしている。 [Second Embodiment]
In the coaxial cable connecting member 10 in the first embodiment, the upper right side and the left side are inclined surface portions 16. This is to reduce the thickness around the opening 15 so that the coaxial cable connecting member 10 is uniformly heated. That is, when the solder is supplied from the opening 15, the periphery of the opening 15 of the coaxial cable connecting member 10 is uniformly heated, so that the solder enters the outer conductor 33 of the coaxial cable 30 due to capillary action, and the outer conductor 33 is completely removed. Around the circumference, it was soldered to the coaxial cable connecting member 10 (region δ in FIGS. 6B and 6C).
In the second embodiment, the shape of the periphery of the opening 15 of the coaxial cable connecting member 10 is different from that of the first embodiment.
　図１４は、第２の実施の形態における同軸ケーブル接続部材１０の一例を説明する図である。図１４（ａ）は、正面図、図１４（ｂ）は、平面図、図１４（ｃ）は、側面図、図１４（ｄ）は、斜視図である。
　第２の実施の形態における同軸ケーブル接続部材１０は、第１の実施の形態における開口部１４及び傾斜面部１６の代わりに、開口１５を有し、貫通孔１２と同心の半円筒状の曲面部１８を備えている。なお、他の構成は、図１で示した第１の実施の形態における同軸ケーブル接続部材１０と同様であるので、同じ符号を付して説明を省略する。
　半円筒状の曲面部１８の形状は、必ずしも貫通孔１２と同心でなくともよく、なだらかな曲面であってもよい。 FIG. 14 is a diagram illustrating an example of the coaxial cable connecting member 10 according to the second embodiment. 14 (a) is a front view, FIG. 14 (b) is a plan view, FIG. 14 (c) is a side view, and FIG. 14 (d) is a perspective view.
The coaxial cable connecting member 10 in the second embodiment has an opening 15 instead of the opening 14 and the inclined surface portion 16 in the first embodiment, and is a semi-cylindrical curved portion concentric with the through-hole 12. 18 is provided. The other configuration is the same as that of the coaxial cable connecting member 10 in the first embodiment shown in FIG.
The shape of the semi-cylindrical curved surface portion 18 does not necessarily have to be concentric with the through hole 12 and may be a gently curved surface.
　このようにすることで、同軸ケーブル接続部材１０は、貫通孔１２の周囲の肉厚の差がより小さくなって、均一に加熱されるようになる。つまり、開口１５からはんだを供給すると、同軸ケーブル接続部材１０の開口１５の周囲が均一に加熱され、はんだが毛細管現象により同軸ケーブル３０の外部導体３３に侵入し、外部導体３３が全周において、同軸ケーブル接続部材１０とはんだ付けされる（図６（ｂ）、（ｃ）参照）。 By doing in this way, the coaxial cable connecting member 10 becomes evenly heated with a smaller difference in thickness around the through hole 12. That is, when the solder is supplied from the opening 15, the periphery of the opening 15 of the coaxial cable connecting member 10 is uniformly heated, the solder enters the outer conductor 33 of the coaxial cable 30 by capillary action, and the outer conductor 33 is around the entire circumference. It is soldered to the coaxial cable connecting member 10 (see FIGS. 6B and 6C).
　なお、第２の実施の形態における同軸ケーブル接続部材１０は、第１の実施の形態で説明した通信回路及び通信装置に適用できる。 Note that the coaxial cable connecting member 10 in the second embodiment can be applied to the communication circuit and the communication device described in the first embodiment.
［第３の実施の形態］
　第１の実施の形態及び第２の実施の形態では、同軸ケーブル接続部材１０は、回路基板２０が挿入される側に、張出部１７を備えていた。
　第３の実施の形態における同軸ケーブル接続部材１０は、同軸ケーブル３０が挿入される側にも、張出部を備えている。 [Third Embodiment]
In the first embodiment and the second embodiment, the coaxial cable connecting member 10 includes the overhanging portion 17 on the side where the circuit board 20 is inserted.
The coaxial cable connecting member 10 according to the third embodiment includes an overhang portion on the side where the coaxial cable 30 is inserted.
　図１５は、第３の実施の形態における同軸ケーブル接続部材１０の一例を説明する図である。図１５（ａ）は、正面図、図１５（ｂ）は、平面図、図１５（ｃ）は、側面図、図１５（ｄ）は、斜視図である。
　第３の実施の形態における同軸ケーブル接続部材１０は、図１に示した第１の実施の形態における同軸ケーブル接続部材１０に、張出部１９をさらに設けている。張出部１９は、貫通孔１２に対して、張出部１７と反対側に設けられている。なお、他の構成は、図１で示した第１の実施の形態における同軸ケーブル接続部材１０と同様であるので、同じ符号を付して説明を省略する。 FIG. 15 is a diagram illustrating an example of the coaxial cable connecting member 10 according to the third embodiment. 15A is a front view, FIG. 15B is a plan view, FIG. 15C is a side view, and FIG. 15D is a perspective view.
The coaxial cable connection member 10 according to the third embodiment further includes an overhang portion 19 in the coaxial cable connection member 10 according to the first embodiment shown in FIG. The overhanging portion 19 is provided on the opposite side of the overhanging portion 17 with respect to the through hole 12. The other configuration is the same as that of the coaxial cable connecting member 10 in the first embodiment shown in FIG.
　第３の実施の形態における同軸ケーブル接続部材１０の張出部１９も、同軸ケーブル接続部材１０として一体に構成されている。よって、図１５（ａ）、（ｂ）、（ｃ）では、張出部１９も、一点鎖線で区切って示している。 The overhanging portion 19 of the coaxial cable connecting member 10 in the third embodiment is also integrally formed as the coaxial cable connecting member 10. Therefore, in FIGS. 15A, 15 </ b> B, and 15 </ b> C, the overhanging portion 19 is also indicated by a dashed line.
　図１６は、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付ける方法及び取り付けた状態を説明する図である。図１６（ａ）は、同軸ケーブル接続部材１０と同軸ケーブル３０とを対向させた状態、図１６（ｂ）は、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付けた状態を同軸ケーブル３０側から見た図、図１６（ｃ）は、同軸ケーブル接続部材１０に同軸ケーブル３０を取り付けた状態を回路基板２０側から見た図である。
　同軸ケーブル接続部材１０には、回路基板２０が既に取り付けられている。 FIG. 16 is a diagram for explaining a method of attaching the coaxial cable 30 to the coaxial cable connecting member 10 and the attached state. 16A shows a state in which the coaxial cable connecting member 10 and the coaxial cable 30 are opposed to each other, and FIG. 16B shows a state in which the coaxial cable 30 is attached to the coaxial cable connecting member 10 from the coaxial cable 30 side. FIG. 16C is a view of the state where the coaxial cable 30 is attached to the coaxial cable connecting member 10 as viewed from the circuit board 20 side.
The circuit board 20 is already attached to the coaxial cable connecting member 10.
　図１６（ａ）に示すように、同軸ケーブル接続部材１０における貫通孔１２の回路基板２０とは反対側に、同軸ケーブル３０を対向させる。このとき、張出部１９が同軸ケーブル３０側に張り出している。 As shown in FIG. 16A, the coaxial cable 30 is made to face the opposite side of the through hole 12 in the coaxial cable connecting member 10 from the circuit board 20. At this time, the overhang portion 19 projects to the coaxial cable 30 side.
　図１６（ｂ）に示すように、同軸ケーブル接続部材１０の貫通孔１２のテーパ面１２Ａ側から、同軸ケーブル３０が貫通孔１２に挿入される。そして、同軸ケーブル３０の内部導体３１を露出させた部分が、回路基板２０の信号導体２２上に配置される。そして、外部導体３３を露出させた部分が、回路基板２０の張出部１９上に配置される。
　次に、第１の実施の形態における同軸ケーブル接続部材１０と同様に、領域βにおいて、はんだ付けされる。 As shown in FIG. 16B, the coaxial cable 30 is inserted into the through hole 12 from the tapered surface 12 </ b> A side of the through hole 12 of the coaxial cable connecting member 10. A portion where the inner conductor 31 of the coaxial cable 30 is exposed is disposed on the signal conductor 22 of the circuit board 20. The portion where the external conductor 33 is exposed is disposed on the overhanging portion 19 of the circuit board 20.
Next, similarly to the coaxial cable connecting member 10 in the first embodiment, soldering is performed in the region β.
　領域βにおけるはんだ付けは、同軸ケーブル３０の全周にわたって行われることが好ましい。つまり、同軸ケーブル接続部材１０の貫通孔１２の同軸ケーブル３０を挿入した端部と、同軸ケーブル３０の外部導体３３とが、全周において、はんだ付けされることが好ましい。 Soldering in the region β is preferably performed over the entire circumference of the coaxial cable 30. That is, it is preferable that the end portion of the through hole 12 of the coaxial cable connecting member 10 into which the coaxial cable 30 is inserted and the outer conductor 33 of the coaxial cable 30 are soldered on the entire circumference.
　図６に示した、第１の実施の形態における同軸ケーブル接続部材１０のように、張出部１９を備えない場合、上側から領域βにはんだを供給してはんだ付けすると、上側からでは目視できない下側にはんだが回ったか否かが判断しづらい。したがって、回路基板２０を裏返して、下側にはんだが回ったか否かを判断することが必要となるおそれがある。
　すなわち、回路基板２０に同軸ケーブル３０を取り付ける作業が複雑になってしまう。 In the case where the overhanging portion 19 is not provided as in the coaxial cable connecting member 10 in the first embodiment shown in FIG. 6, when solder is supplied from the upper side to the region β and soldered, it cannot be visually observed from the upper side. It is difficult to judge whether the solder has turned down. Therefore, it may be necessary to turn the circuit board 20 over and determine whether the solder has turned downward.
That is, the operation of attaching the coaxial cable 30 to the circuit board 20 becomes complicated.
　しかし、張出部１９を備えれば、はんだが下側に回ると、はんだが張出部１９上にはみ出してくる。よって、下側にはんだが回ったか否かの判断が容易になる。このために、回路基板２０を裏返すことを要しない。
　よって、回路基板２０に同軸ケーブル３０を取り付ける作業が簡易になる。 However, if the overhanging portion 19 is provided, when the solder turns downward, the solder protrudes onto the overhanging portion 19. Therefore, it becomes easy to determine whether or not the solder has turned downward. For this reason, it is not necessary to turn the circuit board 20 over.
Therefore, the work of attaching the coaxial cable 30 to the circuit board 20 is simplified.
　なお、第３の実施の形態における同軸ケーブル接続部材１０を、第１の実施の形態で説明した通信回路及び通信装置に適用できる。
　また、第３の実施の形態における同軸ケーブル接続部材１０を、第２の実施の形態における同軸ケーブル接続部材１０と同様に、上側を曲面部１８としてもよい。 The coaxial cable connecting member 10 in the third embodiment can be applied to the communication circuit and the communication device described in the first embodiment.
Moreover, the coaxial cable connecting member 10 in the third embodiment may have the curved surface portion 18 on the upper side, similarly to the coaxial cable connecting member 10 in the second embodiment.
［第４の実施の形態］
　第１の実施の形態から第３の実施の形態における同軸ケーブル接続部材１０では、貫通孔１２は、テーパ面１２Ａを除いて、内径Ｈであるとした。そして、露出させた外部導体３３が、貫通孔１２の内面と対向するようにした。
　第４の実施の形態における同軸ケーブル接続部材１０は、貫通孔１２の形状が異なっている。よって、以下では、異なる部分を説明し、同様な部分の説明を省略する。 [Fourth Embodiment]
In the coaxial cable connecting member 10 according to the first to third embodiments, the through hole 12 has the inner diameter H except for the tapered surface 12A. The exposed outer conductor 33 is made to face the inner surface of the through hole 12.
The coaxial cable connecting member 10 in the fourth embodiment is different in the shape of the through hole 12. Therefore, below, a different part is demonstrated and description of the same part is abbreviate | omitted.
　図１７は、第４の実施の形態における同軸ケーブル接続部材１０を説明する図である。図１７（ａ）は、同軸ケーブル接続部材１０の正面図、図１７（ｂ）は、図１７（ａ）のＸＶＩＩＢ－ＸＶＩＩＢ線での第４の実施の形態における同軸ケーブル接続部材１０の断面図、図１７（ｃ）は、図１７（ａ）のＸＶＩＩＢ－ＸＶＩＩＢ線での第１の実施の形態における同軸ケーブル接続部材１０の断面図である。なお、図１７（ｂ）及び図１７（ｃ）では、同軸ケーブル３０を合わせて示している。 FIG. 17 is a diagram illustrating the coaxial cable connecting member 10 according to the fourth embodiment. 17A is a front view of the coaxial cable connecting member 10, and FIG. 17B is a cross-sectional view of the coaxial cable connecting member 10 according to the fourth embodiment taken along the line XVIIB-XVIIB in FIG. FIG. 17C is a cross-sectional view of the coaxial cable connecting member 10 in the first embodiment taken along the line XVIIB-XVIIB in FIG. In FIGS. 17B and 17C, the coaxial cable 30 is also shown.
　図１７（ａ）に示すように、第４の実施の形態における同軸ケーブル接続部材１０の正面図は、大略において、図１（ａ）に示した第１の実施の形態と同じである。
　図１７（ｂ）に示すように、第４の実施の形態における同軸ケーブル接続部材１０の貫通孔１２は、前後方向において、直径が２段になっている。すなわち、後側が内径Ｈ１、前側が内径Ｈ２であって、内径Ｈ１が内径Ｈ２より大きい。
　そして、貫通孔１２の後側の内径Ｈ１の部分に、同軸ケーブル３０の外部導体３３の露出された部分が対向し、前側の内径Ｈ２の部分に、誘電体３２が露出された部分が対向する。すなわち、内径Ｈ１と内径Ｈ２との差は、外部導体３３の厚さに対応して設定される。 As shown in FIG. 17A, the front view of the coaxial cable connecting member 10 in the fourth embodiment is roughly the same as the first embodiment shown in FIG.
As shown in FIG. 17B, the through hole 12 of the coaxial cable connecting member 10 in the fourth embodiment has a two-stage diameter in the front-rear direction. That is, the rear side has an inner diameter H1, the front side has an inner diameter H2, and the inner diameter H1 is larger than the inner diameter H2.
The exposed portion of the outer conductor 33 of the coaxial cable 30 faces the portion of the inner diameter H1 on the rear side of the through hole 12, and the exposed portion of the dielectric 32 faces the portion of the inner diameter H2 on the front side. . That is, the difference between the inner diameter H1 and the inner diameter H2 is set corresponding to the thickness of the outer conductor 33.
　なお、図１７（ｃ）に示すように、第１の実施の形態における同軸ケーブル接続部材１０の貫通孔１２は、内径Ｈ（＝内径Ｈ１）の１段である。すなわち、貫通孔１２には、同軸ケーブル３０の外部導体３３が露出した部分が対向する。
　このため、誘電体３２の端面と外部導体３３の端面とが、同じ平面内にあるように、内部導体３１を露出させることになる。外部導体３３が網組み銅線などである場合には、網組されていた銅線が解れて、内部導体３１に接触するおそれがある。 In addition, as shown in FIG.17 (c), the through-hole 12 of the coaxial cable connection member 10 in 1st Embodiment is 1 step | paragraph of the internal diameter H (= internal diameter H1). That is, the exposed portion of the outer conductor 33 of the coaxial cable 30 faces the through hole 12.
For this reason, the inner conductor 31 is exposed so that the end face of the dielectric 32 and the end face of the outer conductor 33 are in the same plane. If the outer conductor 33 is a braided copper wire or the like, the braided copper wire may break and come into contact with the inner conductor 31.
　これに対し、図１７（ｂ）で示した第４の実施の形態の同軸ケーブル接続部材１０では、誘電体３２を露出させた部分（図１７（ｂ）のＬ２で示す部分）を備えるので、例え、外部導体３３の網組み銅線が解れても、内部導体３１に接触することがより抑制される。 On the other hand, the coaxial cable connecting member 10 of the fourth embodiment shown in FIG. 17B includes a portion where the dielectric 32 is exposed (portion indicated by L2 in FIG. 17B). For example, even if the braided copper wire of the outer conductor 33 is broken, the contact with the inner conductor 31 is further suppressed.
　外部導体３３を露出させる部分（図１７（ｂ）のＬ１で示す部分）と誘電体３２を露出させる部分（図１７（ｂ）のＬ２で示す部分）との割合は、取り付けの容易性と、信号伝送特性とで設定すればよい。
　外部導体３３を露出させる部分の長さＬ１、誘電体３２を露出させる部分の長さＬ２、及び内部導体３１を露出させる部分の長さＬ３は、再現よく設定できる。なお、第１の実施の形態の同軸ケーブル接続部材１０では、外部導体３３を露出させる部分の長さＬは、第４の実施の形態の外部導体３３を露出させる部分の長さＬ１と誘電体３２を露出させる部分の長さＬ２との和になる。 The ratio of the portion that exposes the external conductor 33 (portion indicated by L1 in FIG. 17B) and the portion that exposes the dielectric 32 (portion indicated by L2 in FIG. 17B) is easy to install. What is necessary is just to set with signal transmission characteristics.
The length L1 of the portion exposing the outer conductor 33, the length L2 of the portion exposing the dielectric 32, and the length L3 of the portion exposing the inner conductor 31 can be set with good reproducibility. In the coaxial cable connecting member 10 of the first embodiment, the length L of the portion exposing the outer conductor 33 is equal to the length L1 of the portion exposing the outer conductor 33 of the fourth embodiment. 32 and the length L2 of the exposed portion.
　第４の実施の形態における貫通孔１２の直径を２段に設定した同軸ケーブル接続部材１０を、第１の実施の形態から第３の実施の形態に適用してもよい。 The coaxial cable connecting member 10 in which the diameter of the through hole 12 in the fourth embodiment is set in two stages may be applied to the first to third embodiments.
［第５の実施の形態］
　第１の実施の形態における同軸ケーブル接続部材１０の本体部１１は、開口１５が設けられた開口部１４を備えていた。
　第５の実施の形態における同軸ケーブル接続部材１０の本体部１１は、開口部１４を備えていない。同軸ケーブル接続部材１０を除く他の構成は、第１の実施の形態と同様であるので、ここでは同軸ケーブル接続部材１０を説明する。 [Fifth Embodiment]
The main body 11 of the coaxial cable connecting member 10 in the first embodiment includes an opening 14 provided with an opening 15.
The main body 11 of the coaxial cable connecting member 10 in the fifth embodiment does not include the opening 14. Since the configuration other than the coaxial cable connecting member 10 is the same as that of the first embodiment, the coaxial cable connecting member 10 will be described here.
（同軸ケーブル接続部材１０）
　図１８は、第５の実施の形態における同軸ケーブル接続部材１０の一例を説明する図である。図１８（ａ）は、正面図、図１８（ｂ）は、平面図、図１８（ｃ）は、側面図、図１８（ｄ）は、斜視図である。
　第５の実施の形態における同軸ケーブル接続部材１０は、第１の実施の形態における同軸ケーブル接続部材１０の本体部１１において、開口部１４を備えていないため、左右方向に設けられた一対の傾斜面部１６の間が、開口１５になっている。よって、同軸ケーブル３０が保持される部分は、貫通孔１２ではなく保持溝１２′になっている。
　ここでは、本体部１１が保持部の一例である。
　同軸ケーブル接続部材１０における他の構成は、第１の実施の形態における同軸ケーブル接続部材１０と同様であるので、詳細な説明を省略する。 (Coaxial cable connection member 10)
FIG. 18 is a diagram illustrating an example of the coaxial cable connecting member 10 according to the fifth embodiment. 18A is a front view, FIG. 18B is a plan view, FIG. 18C is a side view, and FIG. 18D is a perspective view.
Since the coaxial cable connecting member 10 in the fifth embodiment does not include the opening 14 in the main body 11 of the coaxial cable connecting member 10 in the first embodiment, a pair of slopes provided in the left-right direction. An opening 15 is formed between the surface portions 16. Therefore, the portion where the coaxial cable 30 is held is not the through hole 12 but the holding groove 12 ′.
Here, the main body unit 11 is an example of a holding unit.
Since the other structure in the coaxial cable connection member 10 is the same as that of the coaxial cable connection member 10 in 1st Embodiment, detailed description is abbreviate | omitted.
　第１の実施の形態における同軸ケーブル接続部材１０では、開口部１４が同軸ケーブル３０の外部導体３３の表面の一部を覆っていた。第５の実施の形態における同軸ケーブル接続部材１０では、同軸ケーブル３０の外部導体３３の表面の一部を覆う開口部１４を備えていないため、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３とのはんだ付けがさらに容易になる（第１の実施の形態で示した図６（ｂ）、（ｃ）参照）。 In the coaxial cable connecting member 10 according to the first embodiment, the opening 14 covers a part of the surface of the outer conductor 33 of the coaxial cable 30. The coaxial cable connection member 10 according to the fifth embodiment does not include the opening 14 that covers a part of the surface of the outer conductor 33 of the coaxial cable 30, and thus the coaxial cable connection member 10 and the outer conductor 33 of the coaxial cable 30. (See FIGS. 6B and 6C shown in the first embodiment).
　保持溝１２′は、同軸ケーブル３０の外部導体３３が保持されるように設けられていればよい。同軸ケーブル３０が上下方向（図１８（ａ）、（ｂ）、（ｄ）参照）にずれて固定されることを抑制するため、保持溝１２′の上側に傾斜面部１６が張り出すように設けられていてもよい。すなわち、左右方向に位置する傾斜面部１６の間の距離が、同軸ケーブル３０の外部導体３３の直径（外径）より小さくてもよい。 The holding groove 12 ′ may be provided so that the outer conductor 33 of the coaxial cable 30 is held. In order to prevent the coaxial cable 30 from being displaced and fixed in the vertical direction (see FIGS. 18A, 18B, and 18D), the inclined surface portion 16 is provided so as to protrude above the holding groove 12 ′. It may be done. That is, the distance between the inclined surface portions 16 positioned in the left-right direction may be smaller than the diameter (outer diameter) of the outer conductor 33 of the coaxial cable 30.
　なお、第１の実施の形態における同軸ケーブル接続部材１０のように開口部１４を備えると、回路基板２０及び同軸ケーブル３０を取り付ける前において、同軸ケーブル接続部材１０の傾斜面部１６の間の距離が機械的な外力を受けて変動することが抑制される。 In addition, if the opening part 14 is provided like the coaxial cable connection member 10 in 1st Embodiment, before attaching the circuit board 20 and the coaxial cable 30, the distance between the inclined surface parts 16 of the coaxial cable connection member 10 will be sufficient. Fluctuation due to mechanical external force is suppressed.
　また、開口部１４を備えない構成を、第３の実施の形態における同軸ケーブル接続部材１０に適用してもよい。
　そして、第２の実施の形態における同軸ケーブル接続部材１０と同様に、傾斜面部１６の表面を曲面にしてもよい。
　さらに、第４の実施の形態における同軸ケーブル接続部材１０と同様に、貫通孔１２の直径（内径）を複数に設定してもよい。 Moreover, you may apply the structure which is not provided with the opening part 14 to the coaxial cable connection member 10 in 3rd Embodiment.
And you may make the surface of the inclined surface part 16 into a curved surface similarly to the coaxial cable connection member 10 in 2nd Embodiment.
Furthermore, like the coaxial cable connecting member 10 in the fourth embodiment, the diameter (inner diameter) of the through hole 12 may be set to a plurality.
［第６の実施の形態］
　第１の実施の形態から第４の実施の形態における同軸ケーブル接続部材１０は、挿入溝部１３を備えている（図１参照）。そして、挿入溝部１３の挿入溝１３Ｃに回路基板２０の切欠き部２４が挿入される（図４、図５参照）。すなわち、挿入溝１３Ｃの高さＧは、回路基板２０の厚さＴに対応するように設定されている。
　このため、回路基板２０の厚さＴ毎に、挿入溝１３Ｃの高さＧが異なる同軸ケーブル接続部材１０を用意することになる。
　第６の実施の形態における同軸ケーブル接続部材１０は、厚さＴの異なる回路基板２０に対応する。同軸ケーブル接続部材１０及び回路基板２０を除く他の構成は、第１の実施の形態と同様であるので、ここでは同軸ケーブル接続部材１０及び回路基板２０を説明する。 [Sixth Embodiment]
The coaxial cable connection member 10 in the first to fourth embodiments includes an insertion groove 13 (see FIG. 1). And the notch part 24 of the circuit board 20 is inserted in the insertion groove 13C of the insertion groove part 13 (refer FIG. 4, FIG. 5). That is, the height G of the insertion groove 13 </ b> C is set to correspond to the thickness T of the circuit board 20.
For this reason, the coaxial cable connection member 10 in which the height G of the insertion groove 13C differs for each thickness T of the circuit board 20 is prepared.
The coaxial cable connecting member 10 in the sixth embodiment corresponds to the circuit board 20 having a different thickness T. Since the configuration other than the coaxial cable connecting member 10 and the circuit board 20 is the same as that of the first embodiment, the coaxial cable connecting member 10 and the circuit board 20 will be described here.
（同軸ケーブル接続部材１０）
　図１９は、第６の実施の形態における同軸ケーブル接続部材１０の一例を説明する図である。図１９（ａ）は、平面図、図１９（ｂ）は、正面図、図１９（ｃ）は、側面図、図１９（ｄ）は、裏面図、図１９（ｅ）は、斜視図である。 (Coaxial cable connection member 10)
FIG. 19 is a diagram illustrating an example of the coaxial cable connecting member 10 according to the sixth embodiment. 19 (a) is a plan view, FIG. 19 (b) is a front view, FIG. 19 (c) is a side view, FIG. 19 (d) is a back view, and FIG. 19 (e) is a perspective view. is there.
　同軸ケーブル接続部材１０の構成を、図１９（ｅ）の斜視図に基づいて説明する。
　同軸ケーブル接続部材１０は、点線で囲って示されている本体部１１と、本体部１１から張り出した挿入部４２とを備えている。なお、本体部１１は、第１の実施の形態における同軸ケーブル接続部材１０の本体部１１の挿入溝部１３を備えない代わりに、回路基板２０に接触する接触部４１を備える。
　同軸ケーブル接続部材１０の本体部１１は、正面中央部に、同軸ケーブル３０（図３参照）が挿入される貫通孔１２を備えている。貫通孔１２は、同軸ケーブル接続部材１０を前後方向に貫通している（図１９（ｃ）参照）。
　本体部１１が、同軸ケーブル３０を保持する保持部の一例である。 The configuration of the coaxial cable connecting member 10 will be described based on the perspective view of FIG.
The coaxial cable connecting member 10 includes a main body portion 11 surrounded by a dotted line and an insertion portion 42 protruding from the main body portion 11. The main body 11 includes a contact portion 41 that contacts the circuit board 20 instead of including the insertion groove 13 of the main body 11 of the coaxial cable connecting member 10 according to the first embodiment.
The main body 11 of the coaxial cable connecting member 10 includes a through hole 12 into which the coaxial cable 30 (see FIG. 3) is inserted at the front center. The through hole 12 penetrates the coaxial cable connecting member 10 in the front-rear direction (see FIG. 19C).
The main body 11 is an example of a holding unit that holds the coaxial cable 30.
　そして、貫通孔１２の上側にはんだを供給するための開口１５を有する開口部１４を備えている。開口１５は、前側の端部に至るが、後側の端部には達していない（図１９（ｅ）参照）。ここでは、開口１５は、表面形状を一方が開いたＵ字状としたが、閉じた円形であってもよく、他の形状であってもよい。また、はんだの供給が貫通孔１２の入り口から行える場合には、開口１５を備えなくてもよい。 And the opening part 14 which has the opening 15 for supplying solder to the upper side of the through-hole 12 is provided. The opening 15 reaches the front end, but does not reach the rear end (see FIG. 19E). Here, the opening 15 has a U shape with one open surface, but may be a closed circle or another shape. Further, when the solder can be supplied from the entrance of the through hole 12, the opening 15 may not be provided.
　さらに、同軸ケーブル接続部材１０の上側の左側及び右側のそれぞれは、下側に向かって斜めになった傾斜面部１６となっている（図１９（ｂ）参照）。貫通孔１２を取り巻く肉厚の変動が少なくなるとともに、同軸ケーブル接続部材１０の熱容量が小さくなっている。
　これにより、同軸ケーブル接続部材１０と同軸ケーブル３０の露出させた外部導体３３とのはんだ付けが容易にできるようになっている。
　なお、貫通孔１２、開口部１４及び傾斜面部１６は、第１の実施の形態における同軸ケーブル接続部材１０と同様であるので、詳細な説明を省略する。 Furthermore, each of the upper left side and the right side of the coaxial cable connecting member 10 is an inclined surface portion 16 that is inclined downward (see FIG. 19B). The variation in the thickness surrounding the through hole 12 is reduced, and the heat capacity of the coaxial cable connecting member 10 is reduced.
As a result, the coaxial cable connecting member 10 and the exposed outer conductor 33 of the coaxial cable 30 can be easily soldered.
Since the through hole 12, the opening 14, and the inclined surface 16 are the same as those of the coaxial cable connecting member 10 in the first embodiment, detailed description thereof is omitted.
　また、貫通孔１２の左右方向の外側には、回路基板２０の切欠き部２４（後述する図２０参照）に挿入される挿入部４２を備えている。挿入部４２は、貫通孔１２を挟むように、左側及び右側にそれぞれ挿入凸部４２Ａを備えている。また、挿入部４２は、貫通孔１２の前側の端部に凸部の一例としての挿入凸部４２Ｂを備えている。すなわち、挿入凸部４２Ａは、貫通孔１２の孔方向に沿って設けられ、挿入凸部４２Ｂは、貫通孔１２の孔方向に直交する方向に飛び出すように設けられている。そして、挿入凸部４２Ａ、４２Ｂは、貫通孔１２から下側に延びている。なお、挿入凸部４２Ｂは、貫通孔１２の孔方向に交差する方向に飛び出すように設けられていればよい。
　そして、同軸ケーブル接続部材１０における本体部１１は、挿入部４２が後述する回路基板２０の切欠き部２４に挿入された際に、回路基板２０の面に接する一対の接触部４１を備えている。接触部４１は、貫通孔１２の孔方向に沿って、貫通孔１２側から左右方向に延びて設けられている。すなわち、接触部４１は、回路基板２０の表面に対して、同軸ケーブル３０の長手方向において、面で接触する。 Further, an insertion portion 42 to be inserted into a notch portion 24 (see FIG. 20 described later) of the circuit board 20 is provided outside the through hole 12 in the left-right direction. The insertion portion 42 includes insertion convex portions 42A on the left side and the right side so as to sandwich the through hole 12. Further, the insertion portion 42 includes an insertion convex portion 42B as an example of a convex portion at the front end portion of the through hole 12. That is, the insertion convex portion 42 </ b> A is provided along the hole direction of the through hole 12, and the insertion convex portion 42 </ b> B is provided so as to protrude in a direction orthogonal to the hole direction of the through hole 12. The insertion convex portions 42A and 42B extend downward from the through hole 12. In addition, the insertion convex part 42B should just be provided so that it may protrude in the direction which cross | intersects the hole direction of the through-hole 12. FIG.
And the main-body part 11 in the coaxial cable connection member 10 is provided with a pair of contact part 41 which contact | connects the surface of the circuit board 20, when the insertion part 42 is inserted in the notch part 24 of the circuit board 20 mentioned later. . The contact portion 41 is provided so as to extend in the left-right direction from the through hole 12 side along the hole direction of the through hole 12. That is, the contact portion 41 comes into contact with the surface of the circuit board 20 in the longitudinal direction of the coaxial cable 30.
　接触部４１の前側の端部は、挿入凸部４２Ｂに繋がっている。同様に、挿入凸部４２Ａの前側の端部も、挿入凸部４２Ｂに繋がっている。また、挿入凸部４２Ｂと接触部４１とは、貫通孔１２の孔方向において繋がっている。
　なお、接触部４１と挿入凸部４２Ｂとが繋がる部分の内、回路基板２０側となる部分５１（図１９（ｃ）参照）、及び、接触部４１と挿入凸部４２Ａとが繋がる部分の内、回路基板２０側となる部分５２（図１９（ｄ））には、予め定められた曲率（例えば、０．３ｍｍ）の窪みが形成されている。
　これにより、回路基板２０の表面及び側面が、接触部４１及び挿入凸部４２Ｂに容易に密着できるようになっている。 The front end of the contact portion 41 is connected to the insertion convex portion 42B. Similarly, the front end portion of the insertion convex portion 42A is also connected to the insertion convex portion 42B. Further, the insertion convex portion 42 </ b> B and the contact portion 41 are connected in the hole direction of the through hole 12.
Of the portion where the contact portion 41 and the insertion convex portion 42B are connected, the portion 51 on the circuit board 20 side (see FIG. 19C) and the portion where the contact portion 41 and the insertion convex portion 42A are connected. A recess having a predetermined curvature (for example, 0.3 mm) is formed in the portion 52 (FIG. 19D) on the circuit board 20 side.
Thereby, the surface and side surface of the circuit board 20 can be easily adhered to the contact portion 41 and the insertion convex portion 42B.
　また、図１９（ｄ）に示すように、一対の挿入凸部４２Ａの間の部分５３は、空隙とした。これは、貫通孔１２の周りの厚さの変動を抑制し、熱容量のばらつきを低減するためである。これにより、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３との間におけるはんだ付けの、外部導体３３の外周方向におけるばらつきが抑制される。
　なお、図１９（ａ）、（ｂ）、（ｃ）、（ｄ）、（ｅ）において、同軸ケーブル接続部材１０の外面（外側の面）の交差部分に丸みを設けたが、丸みを設けなくてもよい。 Moreover, as shown in FIG.19 (d), the part 53 between 42 A of a pair of insertion convex parts was made into the space | gap. This is to suppress variation in thickness around the through hole 12 and reduce variation in heat capacity. Thereby, the dispersion | variation in the outer peripheral direction of the external conductor 33 of the soldering between the coaxial cable connection member 10 and the external conductor 33 of the coaxial cable 30 is suppressed.
19 (a), (b), (c), (d), and (e), the rounded portion is provided at the intersection of the outer surface (outer surface) of the coaxial cable connecting member 10, but the roundness is provided. It does not have to be.
　同軸ケーブル接続部材１０は、長さがＭ、挿入凸部４２Ｂの幅がＷ１、一対の挿入凸部４２Ａの外側間の距離がＷ２である。そして、貫通孔１２の内径Ｈが３．８ｍｍである。
　なお、同軸ケーブル接続部材１０は、左右方向で対称である。よって、右側又は左側の一方にのみ符号を付している。以下同様である。 In the coaxial cable connecting member 10, the length is M, the width of the insertion convex portion 42B is W1, and the distance between the outer sides of the pair of insertion convex portions 42A is W2. And the internal diameter H of the through-hole 12 is 3.8 mm.
The coaxial cable connecting member 10 is symmetrical in the left-right direction. Therefore, only one of the right side and the left side is given a reference numeral. The same applies hereinafter.
　同軸ケーブル接続部材１０は、第１の実施の形態における同軸ケーブル接続部材１０と同様に、銅、真鍮、アルミニウム、亜鉛などの導電体材料で構成されている。同軸ケーブル接続部材１０は、導電体材料から削り出しにより製造できる。また、金型鋳造（ダイカスト）により製造することもできる。融点が低い亜鉛は、ダイカストによる同軸ケーブル接続部材１０の製造をより容易にする。
　なお、はんだ付けを容易にするため、同軸ケーブル接続部材１０の表面は、錫めっき、金めっき、銀めっき等のめっき処理されることが好ましい。 The coaxial cable connecting member 10 is made of a conductor material such as copper, brass, aluminum, or zinc, as with the coaxial cable connecting member 10 in the first embodiment. The coaxial cable connecting member 10 can be manufactured by cutting out from a conductive material. It can also be manufactured by die casting (die casting). Zinc having a low melting point makes it easier to manufacture the coaxial cable connecting member 10 by die casting.
In order to facilitate soldering, the surface of the coaxial cable connecting member 10 is preferably subjected to a plating treatment such as tin plating, gold plating, or silver plating.
（回路基板２０）
　図２０は、同軸ケーブル接続部材１０が取り付けられる回路基板２０の一例を説明する図である。図２０（ａ）は、表面図、図２０（ｂ）は、図２０（ａ）、（ｃ）のＸＸＢ－ＸＸＢ線での断面図、図２０（ｃ）は裏面図である。
　回路基板２０は、図２に示した第１の実施の形態における回路基板２０と、切欠き部２４の形状が異なっている。切欠き部２４を除く他の構成は、第１の実施の形態と同様であるので、切欠き部２４のみを説明する。 (Circuit board 20)
FIG. 20 is a diagram illustrating an example of the circuit board 20 to which the coaxial cable connecting member 10 is attached. 20A is a front view, FIG. 20B is a sectional view taken along line XXB-XXB in FIGS. 20A and 20C, and FIG. 20C is a rear view.
The circuit board 20 is different from the circuit board 20 in the first embodiment shown in FIG. Since the configuration other than the notch 24 is the same as that of the first embodiment, only the notch 24 will be described.
　図２に示した第１の実施の形態における回路基板２０では、切欠き部２４は、コ字状に側面２４Ａ、２４Ｂ、２４Ｃで構成されていた。ここでは、切欠き部２４は、側面２４Ａ、２４Ｂ、２４Ｃに加えて、側面２４Ｄ、２４Ｅが付け加えられている。側面２４Ｄが、側面２４Ａと側面２４Ｃとの接続部分に位置し、側面２４Ｅが、側面２４Ｂと側面２４Ｃとの接続部分に位置している。そして、側面２４Ｄと側面２４Ｅとが対向する部分が、対向する側面２４Ａと側面２４Ｃの間の幅Ｓより広くなっている。
　なお、側面２４Ｄと側面２４Ｅの形状は、同軸ケーブル接続部材１０の挿入凸部４２Ｂの形状に応じて設定されている。ここでは、円弧を有する形状に形成されている。 In the circuit board 20 in the first embodiment shown in FIG. 2, the cutout portion 24 is configured by the side surfaces 24A, 24B, and 24C in a U-shape. Here, in addition to the side surfaces 24A, 24B, and 24C, the cutout portion 24 has side surfaces 24D and 24E added thereto. The side surface 24D is located at the connection portion between the side surface 24A and the side surface 24C, and the side surface 24E is located at the connection portion between the side surface 24B and the side surface 24C. A portion where the side surface 24D and the side surface 24E face each other is wider than the width S between the facing side surface 24A and the side surface 24C.

（回路基板２０への同軸ケーブル接続部材１０の取り付け方法）
　図２１は、同軸ケーブル接続部材１０により回路基板２０に同軸ケーブル３０を取り付けた状態を説明する図である。図２１（ａ）は、回路基板２０の表面側から見た図、図２１（ｂ）は、回路基板２０の裏面側から見た図である。
　図２１（ａ）、（ｂ）に示すように、同軸ケーブル接続部材１０の挿入部４２が、回路基板２０の切欠き部２４に、回路基板２０の表面側から挿入されて、同軸ケーブル接続部材１０と回路基板２０とが嵌合している。 (Method of attaching the coaxial cable connecting member 10 to the circuit board 20)
FIG. 21 is a diagram illustrating a state where the coaxial cable 30 is attached to the circuit board 20 by the coaxial cable connecting member 10. FIG. 21A is a diagram viewed from the front surface side of the circuit board 20, and FIG. 21B is a diagram viewed from the back surface side of the circuit board 20.
As shown in FIGS. 21A and 21B, the insertion portion 42 of the coaxial cable connecting member 10 is inserted into the cutout portion 24 of the circuit board 20 from the surface side of the circuit board 20, and the coaxial cable connecting member is inserted. 10 and the circuit board 20 are fitted.
　図２１（ａ）に示すように、同軸ケーブル接続部材１０における挿入部４２の挿入凸部４２Ｂが、回路基板２０の切欠き部２４の側面２４Ｃ、２４Ｄ、２４Ｅに嵌めこまれている。これにより、回路基板２０と同軸ケーブル接続部材１０との前後方向におけるずれが抑制される。
　また、同軸ケーブル接続部材１０の本体部１１における接触部４１が、同軸ケーブル３０の長手方向に沿って回路基板２０の表面に接触するので、同軸ケーブル３０の内部導体３１と回路基板２０の表面の信号導体２２との位置関係がずれることが抑制されるとともに、同軸ケーブル接続部材１０が同軸ケーブル３０の長手方向（図２１（ａ）の前後方向）において傾くことが抑制される。 As shown in FIG. 21A, the insertion convex portion 42 </ b> B of the insertion portion 42 in the coaxial cable connecting member 10 is fitted into the side surfaces 24 </ b> C, 24 </ b> D, 24 </ b> E of the notch portion 24 of the circuit board 20. Thereby, the shift | offset | difference in the front-back direction of the circuit board 20 and the coaxial cable connection member 10 is suppressed.
Further, since the contact portion 41 in the main body portion 11 of the coaxial cable connecting member 10 contacts the surface of the circuit board 20 along the longitudinal direction of the coaxial cable 30, the inner conductor 31 of the coaxial cable 30 and the surface of the circuit board 20 are in contact with each other. The positional relationship with the signal conductor 22 is suppressed from shifting, and the coaxial cable connecting member 10 is suppressed from being inclined in the longitudinal direction of the coaxial cable 30 (the front-rear direction in FIG. 21A).
　そして、第１の実施の形態における図５（ｂ）に示したと同様に、回路基板２０の裏面の基準導体２３と同軸ケーブル接続部材１０とがはんだ付けされる（図２１（ｂ）の領域α）。また、第１の実施の形態における図６（ｂ）に示したと同様に、同軸ケーブル３０の外部導体３３と同軸ケーブル接続部材１０とが、開口部１４の開口１５を通してはんだ付けされる（図２１（ａ）の領域δ）。さらに、第１の実施の形態における図６（ｃ）に示したと同様に、同軸ケーブル３０の内部導体３１と回路基板２０の信号導体２２とがはんだ付けされる（図２１（ａ）の領域γ）。
　なお、図２１（ａ）、（ｂ）に図示しないが、第１の実施の形態における図６（ｂ）の領域βと同様に、同軸ケーブル３０の外部導体３３と同軸ケーブル接続部材１０とが、回路基板２０の外側（図２１（ａ）の後側）においてはんだ付けされる。 Then, as shown in FIG. 5B in the first embodiment, the reference conductor 23 on the back surface of the circuit board 20 and the coaxial cable connecting member 10 are soldered (region α in FIG. 21B). ). Similarly to the first embodiment shown in FIG. 6B, the outer conductor 33 of the coaxial cable 30 and the coaxial cable connecting member 10 are soldered through the opening 15 of the opening 14 (FIG. 21). (A) region δ). Further, as shown in FIG. 6C in the first embodiment, the inner conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20 are soldered (region γ in FIG. 21A). ).
Although not shown in FIGS. 21A and 21B, the outer conductor 33 of the coaxial cable 30 and the coaxial cable connecting member 10 are connected in the same manner as the region β in FIG. 6B in the first embodiment. The soldering is performed on the outside of the circuit board 20 (the rear side in FIG. 21A).
　同軸ケーブル接続部材１０を用いた回路基板２０と同軸ケーブル３０との接続する方法として、回路基板２０と同軸ケーブル接続部材１０とを領域αではんだ付けして固定した後、同軸ケーブル３０を貫通孔１２に挿入して、同軸ケーブル３０と回路基板２０及び同軸ケーブル接続部材１０とを領域β、δ、γにおいてはんだ付けして固定することで、回路基板２０と同軸ケーブル３０とを接続してもよい。
　また、同軸ケーブル接続部材１０の貫通孔１２に同軸ケーブル３０を挿入して、領域β、δではんだ付けして固定した後、同軸ケーブル接続部材１０を回路基板２０の切欠き部２４に挿入して、領域α、γをはんだ付けして固定することで、回路基板２０と同軸ケーブル３０とを接続してもよい。 As a method of connecting the circuit board 20 and the coaxial cable 30 using the coaxial cable connecting member 10, the circuit board 20 and the coaxial cable connecting member 10 are soldered and fixed in the region α, and then the coaxial cable 30 is passed through the through hole. 12, the coaxial cable 30, the circuit board 20, and the coaxial cable connecting member 10 are soldered and fixed in the regions β, δ, and γ, so that the circuit board 20 and the coaxial cable 30 can be connected. Good.
Further, after inserting the coaxial cable 30 into the through hole 12 of the coaxial cable connecting member 10 and soldering and fixing it in the regions β and δ, the coaxial cable connecting member 10 is inserted into the notch 24 of the circuit board 20. Then, the circuit board 20 and the coaxial cable 30 may be connected by soldering and fixing the regions α and γ.
　なお、図２１（ｂ）から分かるように、同軸ケーブル接続部材１０と回路基板２０の基準導体２３とをはんだ付けした領域αが、第１の実施の形態の同軸ケーブル接続部材１０における張出部１７として機能する。すなわち、はんだ付けした領域αは、同軸ケーブル３０の内部導体３１に対してストリップライン（線路）を構成する。よって、第１の実施の形態における図８で説明したように、同軸ケーブル３０と回路基板２０との接続によって生じるインピーダンスの変動が抑制される。 As can be seen from FIG. 21B, the region α where the coaxial cable connecting member 10 and the reference conductor 23 of the circuit board 20 are soldered is an overhang portion in the coaxial cable connecting member 10 of the first embodiment. 17 functions. That is, the soldered region α forms a strip line (line) with respect to the inner conductor 31 of the coaxial cable 30. Therefore, as described with reference to FIG. 8 in the first embodiment, fluctuations in impedance caused by the connection between the coaxial cable 30 and the circuit board 20 are suppressed.
（信号反射特性）
　次に、第１の実施の形態における同軸ケーブル接続部材１０（実施例１と表記する。）を用いて回路基板２０と同軸ケーブル３０とを接続した場合と、第６の実施の形態の同軸ケーブル接続部材１０（実施例２と表記する。）を用いて回路基板２０と同軸ケーブル３０とを接続した場合とにおける信号反射特性を説明する。 (Signal reflection characteristics)
Next, the case where the circuit board 20 and the coaxial cable 30 are connected using the coaxial cable connecting member 10 (denoted as Example 1) in the first embodiment, and the coaxial cable of the sixth embodiment. The signal reflection characteristics when the circuit board 20 and the coaxial cable 30 are connected using the connection member 10 (denoted as Example 2) will be described.
　実施例１の同軸ケーブル接続部材１０については、既に説明した。すなわち、同軸ケーブル接続部材１０は、本体部１１の長さＭが５．０ｍｍ、張出部１７の長さＮが１．８ｍｍ、貫通孔１２の内径Ｈが３．８ｍｍ、挿入溝部１３の高さＧが１．６ｍｍ、挿入溝部１３間の間隔Ｗが４．６ｍｍである。実施例１の同軸ケーブル接続部材１０は、外部導体３３の外径が３．６ｍｍの同軸ケーブル３０、及び、厚さＴが１．６ｍｍの回路基板２０に対応するように構成されている。
　また、回路基板２０は、切欠き部２４の幅Ｓが４．８ｍｍ、切欠き部２４の深さＵが５．０ｍｍである。 The coaxial cable connecting member 10 of Example 1 has already been described. That is, the coaxial cable connecting member 10 has a length M of the main body 11 of 5.0 mm, a length N of the overhang 17 of 1.8 mm, an inner diameter H of the through hole 12 of 3.8 mm, and a height of the insertion groove 13. The length G is 1.6 mm, and the interval W between the insertion groove portions 13 is 4.6 mm. The coaxial cable connecting member 10 according to the first embodiment is configured to correspond to the coaxial cable 30 having an outer diameter of the outer conductor 33 of 3.6 mm and the circuit board 20 having a thickness T of 1.6 mm.
In the circuit board 20, the width S of the notch 24 is 4.8 mm, and the depth U of the notch 24 is 5.0 mm.
　一方、実施例２の同軸ケーブル接続部材１０は、長さＭが５．０ｍｍ、貫通孔１２の内径Ｈが３．８ｍｍである。そして、挿入凸部４２Ｂの幅Ｗ１が７．０ｍｍ、一対の挿入凸部４２Ａの外側間の距離Ｗ２が４．６ｍｍである。実施例２の同軸ケーブル接続部材１０は、外部導体３３の外径が３．６ｍｍの同軸ケーブル３０に対応するように構成されている。なお、回路基板２０の厚さＴに対する制約がない。
　また、回路基板２０は、切欠き部２４の幅Ｓが４．８ｍｍ、切欠き部２４の深さＵが５．０ｍｍである。なお、側面２４Ｄ、２４Ｅの形状は、挿入凸部４２Ｂが挿入可能な形状に構成されている。 On the other hand, the coaxial cable connecting member 10 of Example 2 has a length M of 5.0 mm and an inner diameter H of the through hole 12 of 3.8 mm. And the width W1 of the insertion convex part 42B is 7.0 mm, and the distance W2 between the outer side of a pair of insertion convex part 42A is 4.6 mm. The coaxial cable connecting member 10 of the second embodiment is configured to correspond to the coaxial cable 30 in which the outer diameter of the outer conductor 33 is 3.6 mm. There is no restriction on the thickness T of the circuit board 20.
In the circuit board 20, the width S of the notch 24 is 4.8 mm, and the depth U of the notch 24 is 5.0 mm. In addition, the shape of the side surfaces 24D and 24E is configured so that the insertion convex portion 42B can be inserted.
　図２２は、実施例１の同軸ケーブル接続部材１０と実施例２の同軸ケーブル接続部材１０とそれぞれを用いて、同軸ケーブル３０と厚さＴが０．８ｍｍの回路基板２０とを接続した場合の信号反射特性である。横軸は、周波数（ＧＨｚ）縦軸は、信号反射特性を表すＳパラメータのＳ１１、すなわちリターンロス（ｄＢ）である。リターンロス（ｄＢ）は、小さいほどよい。 FIG. 22 shows a case where the coaxial cable 30 and the circuit board 20 having a thickness T of 0.8 mm are connected using the coaxial cable connection member 10 of Example 1 and the coaxial cable connection member 10 of Example 2, respectively. Signal reflection characteristics. The horizontal axis represents frequency (GHz), and the vertical axis represents S parameter S11 representing signal reflection characteristics, that is, return loss (dB). The smaller the return loss (dB), the better.
　実施例１と実施例２とを比較すると、実施例１が実施例２に比べてリターンロス（ｄＢ）が大きい。
　これは、実施例１（第１の実施の形態）の同軸ケーブル接続部材１０が、厚さＴが１．６ｍｍの回路基板２０に対応するため、厚さＴが０．８ｍｍの回路基板２０に適用すると、同軸ケーブル３０の内部導体３１が回路基板２０の信号導体２２から離れるために生じたインピーダンスの変動によると考えられる。
　つまり、実施例１（第１の実施の形態）の同軸ケーブル接続部材１０では、図５に示したように、まず、裏返した状態の回路基板２０に、同軸ケーブル接続部材１０を挿入され、領域αがはんだ付けされる。すると、回路基板２０の厚さＴが０．８ｍｍであると、本来の厚さＴの１．６ｍｍより薄いため、図６（ａ）に示したように、回路基板２０を表返して、同軸ケーブル３０を貫通孔１２に通すと、内部導体３１の位置が、回路基板２０の表面（信号導体２２）から、０．８ｍｍ離れた位置にくる。このため、同軸ケーブル３０の内部導体３１と回路基板２０の信号導体２２との間に隙間が生じてしまう。ここでは、領域γ（図６（ｂ）、（ｃ）参照）のはんだによってこの隙間を埋めている。
　このため、同軸ケーブル３０の内部導体３１と回路基板２０の信号導体２２との間においてインピーダンスが変動したと考えられる。 When Example 1 is compared with Example 2, Example 1 has a larger return loss (dB) than Example 2.
This is because the coaxial cable connecting member 10 of Example 1 (the first embodiment) corresponds to the circuit board 20 having a thickness T of 1.6 mm, so that the circuit board 20 having a thickness T of 0.8 mm is used. When applied, it is considered that this is due to a variation in impedance that occurs because the inner conductor 31 of the coaxial cable 30 is separated from the signal conductor 22 of the circuit board 20.
That is, in the coaxial cable connection member 10 of Example 1 (first embodiment), as shown in FIG. 5, first, the coaxial cable connection member 10 is inserted into the circuit board 20 in an inverted state, and the region α is soldered. Then, if the thickness T of the circuit board 20 is 0.8 mm, it is thinner than the original thickness T of 1.6 mm. Therefore, as shown in FIG. When the cable 30 is passed through the through hole 12, the position of the internal conductor 31 is 0.8 mm away from the surface (the signal conductor 22) of the circuit board 20. For this reason, a gap is generated between the inner conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20. Here, this gap is filled with solder in the region γ (see FIGS. 6B and 6C).
For this reason, it is considered that the impedance fluctuated between the inner conductor 31 of the coaxial cable 30 and the signal conductor 22 of the circuit board 20.
　図２３は、実施例１の同軸ケーブル接続部材１０と実施例２の同軸ケーブル接続部材１０とをそれぞれ用いて、同軸ケーブル３０と厚さＴが１．６ｍｍの回路基板２０とを接続した場合の信号反射特性である。横軸は、周波数（ＧＨｚ）、縦軸は、信号反射特性を表すＳ１１であって、リターンロス（ｄＢ）である。 FIG. 23 shows a case where the coaxial cable 30 and the circuit board 20 having a thickness T of 1.6 mm are connected using the coaxial cable connection member 10 of Example 1 and the coaxial cable connection member 10 of Example 2, respectively. Signal reflection characteristics. The horizontal axis represents frequency (GHz), and the vertical axis represents S11 representing signal reflection characteristics, which is return loss (dB).
　図２３に示すように、実施例１及び実施例２とも、小さなリターンロス（ｄＢ）を示している。すなわち、実施例１の同軸ケーブル接続部材１０は、厚さＴが１．６ｍｍの回路基板２０に対応しているので、リターンロス（ｄＢ）が小さい。 As shown in FIG. 23, both Example 1 and Example 2 show a small return loss (dB). That is, since the coaxial cable connecting member 10 of Example 1 corresponds to the circuit board 20 having a thickness T of 1.6 mm, the return loss (dB) is small.
　以上説明したように、第６の実施の形態における同軸ケーブル接続部材１０（実施例２）は、回路基板２０の厚さＴに依存することなく、リターンロス（ｄＢ）を小さく抑えている。 As described above, the coaxial cable connecting member 10 (Example 2) in the sixth embodiment suppresses the return loss (dB) to be small without depending on the thickness T of the circuit board 20.
　図２４は、同軸ケーブル接続部材１０の変形例を説明する図である。図２４（ａ）は、挿入凸部４２Ｂの位置を、同軸ケーブル接続部材１０における同軸ケーブル３０の長手方向の中央に設けた場合、図２４（ｂ）は、挿入凸部４２Ｂの位置を、同軸ケーブル接続部材１０における同軸ケーブル３０が挿入される側に設けた場合である。
　いずれにおいても、同軸ケーブル接続部材１０と回路基板２０との前後方向のずれが抑制される。すなわち、同軸ケーブル接続部材１０において挿入凸部４２Ｂを設ける位置は、同軸ケーブル接続部材１０の回路基板２０における前後方向のずれが抑制される位置であればよい。 FIG. 24 is a view for explaining a modification of the coaxial cable connecting member 10. 24A shows a case where the position of the insertion convex portion 42B is provided in the center of the coaxial cable 30 in the longitudinal direction of the coaxial cable 30. FIG. 24B shows the position of the insertion convex portion 42B coaxially. This is a case where the cable connecting member 10 is provided on the side where the coaxial cable 30 is inserted.
In either case, the longitudinal displacement between the coaxial cable connecting member 10 and the circuit board 20 is suppressed. In other words, the position where the insertion convex portion 42B is provided in the coaxial cable connecting member 10 may be a position where a shift in the front-rear direction of the circuit board 20 of the coaxial cable connecting member 10 is suppressed.
　なお、同軸ケーブル接続部材１０の先端を回路基板２０の切欠き部２４の側面２４Ｂに突合させることで、同軸ケーブル接続部材１０と回路基板２０とが位置決めされる場合には、挿入凸部４２Ｂを設けることを要しない。 When the coaxial cable connecting member 10 and the circuit board 20 are positioned by abutting the end of the coaxial cable connecting member 10 with the side surface 24B of the notch 24 of the circuit board 20, the insertion convex part 42B is It is not necessary to provide it.
　また、第２の実施の形態における同軸ケーブル接続部材１０と同様に、傾斜面部１６及び開口部１４を曲面部１８としてもよい。さらに、第４の実施の形態における同軸ケーブル接続部材１０と同様に、貫通孔１２の直径（内径）を複数に設定してもよい。 Further, similarly to the coaxial cable connecting member 10 in the second embodiment, the inclined surface portion 16 and the opening portion 14 may be the curved surface portion 18. Furthermore, like the coaxial cable connecting member 10 in the fourth embodiment, the diameter (inner diameter) of the through hole 12 may be set to a plurality.
［第７の実施の形態］
　第６の実施の形態における同軸ケーブル接続部材１０の本体部１１は、開口１５が設けられた開口部１４を備えていた。
　第７の実施の形態における同軸ケーブル接続部材１０の本体部１１は、開口部１４を備えていない。同軸ケーブル接続部材１０を除く他の構成は、第６の実施の形態と同様であるので、ここでは同軸ケーブル接続部材１０を説明する。 [Seventh Embodiment]
The main body 11 of the coaxial cable connecting member 10 according to the sixth embodiment includes an opening 14 provided with an opening 15.
The main body 11 of the coaxial cable connecting member 10 in the seventh embodiment does not include the opening 14. Since the configuration other than the coaxial cable connecting member 10 is the same as that of the sixth embodiment, the coaxial cable connecting member 10 will be described here.
（同軸ケーブル接続部材１０）
　図２５は、第７の実施の形態における同軸ケーブル接続部材１０の一例を説明する図である。図２５（ａ）は、平面図、図２５（ｂ）は、正面図、図２５（ｃ）は、側面図、図２５（ｄ）は、裏面図、図２５（ｅ）は、斜視図である。
　第７の実施の形態における同軸ケーブル接続部材１０は、第６の実施の形態における同軸ケーブル接続部材１０の本体部１１において、開口部１４を備えていないため、左右方向の傾斜面部１６の間が、開口１５になっている。よって、同軸ケーブル３０が保持される部分は、貫通孔１２ではなく保持溝１２′になっている。
　本体部１１が、同軸ケーブル３０を保持する保持部の一例である。
　同軸ケーブル接続部材１０における他の構成は、第６の実施の形態における同軸ケーブル接続部材１０と同様であるので、詳細な説明を省略する。 (Coaxial cable connection member 10)
FIG. 25 is a diagram illustrating an example of the coaxial cable connecting member 10 according to the seventh embodiment. 25 (a) is a plan view, FIG. 25 (b) is a front view, FIG. 25 (c) is a side view, FIG. 25 (d) is a back view, and FIG. 25 (e) is a perspective view. is there.
Since the coaxial cable connecting member 10 in the seventh embodiment does not include the opening 14 in the main body 11 of the coaxial cable connecting member 10 in the sixth embodiment, the space between the inclined surface portions 16 in the left-right direction is between. , Opening 15. Therefore, the portion where the coaxial cable 30 is held is not the through hole 12 but the holding groove 12 ′.
The main body 11 is an example of a holding unit that holds the coaxial cable 30.
Since the other structure in the coaxial cable connection member 10 is the same as that of the coaxial cable connection member 10 in 6th Embodiment, detailed description is abbreviate | omitted.
　第６の実施の形態における同軸ケーブル接続部材１０では、開口部１４が同軸ケーブル３０の外部導体３３の表面の一部を覆っていた。第７の実施の形態における同軸ケーブル接続部材１０では、同軸ケーブル３０の外部導体３３の表面の一部を覆う開口部１４を備えていないため、同軸ケーブル接続部材１０と同軸ケーブル３０の外部導体３３とのはんだ付けがさらに容易になる（第１の実施の形態で示した図６（ｂ）、（ｃ）参照）。 In the coaxial cable connecting member 10 according to the sixth embodiment, the opening 14 covers a part of the surface of the outer conductor 33 of the coaxial cable 30. The coaxial cable connection member 10 according to the seventh embodiment does not include the opening 14 that covers a part of the surface of the outer conductor 33 of the coaxial cable 30, and thus the coaxial cable connection member 10 and the outer conductor 33 of the coaxial cable 30. (See FIGS. 6B and 6C shown in the first embodiment).
　保持溝１２′は、同軸ケーブル３０の外部導体３３が保持されるように設けられていればよい。同軸ケーブル３０が上下方向（図２５（ａ）、（ｂ）、（ｄ）参照）にずれて固定されることを抑制するため、保持溝１２′の上側に傾斜面部１６が張り出すように設けられていてもよい。すなわち、左右方向に位置する傾斜面部１６の間の距離が、同軸ケーブル３０の外部導体３３の直径（外径）より小さくてもよい。 The holding groove 12 ′ may be provided so that the outer conductor 33 of the coaxial cable 30 is held. In order to prevent the coaxial cable 30 from being displaced and fixed in the vertical direction (see FIGS. 25A, 25B and 25D), the inclined surface portion 16 is provided so as to protrude above the holding groove 12 '. It may be done. That is, the distance between the inclined surface portions 16 positioned in the left-right direction may be smaller than the diameter (outer diameter) of the outer conductor 33 of the coaxial cable 30.
　なお、第６の実施の形態における同軸ケーブル接続部材１０のように開口部１４を備えると、回路基板２０及び同軸ケーブル３０を取り付ける前において、同軸ケーブル接続部材１０の傾斜面部１６の間の距離が機械的な外力を受けて変動することが抑制される。 In addition, if the opening part 14 is provided like the coaxial cable connection member 10 in 6th Embodiment, before attaching the circuit board 20 and the coaxial cable 30, the distance between the inclined surface parts 16 of the coaxial cable connection member 10 will be sufficient. Fluctuation due to mechanical external force is suppressed.
　また、第２の実施の形態における同軸ケーブル接続部材１０と同様に、傾斜面部１６を曲面部１８としてもよい。
　さらに、第４の実施の形態における同軸ケーブル接続部材１０と同様に、貫通孔１２の直径（内径）を複数に設定してもよい。 Further, the inclined surface portion 16 may be a curved surface portion 18 as in the coaxial cable connecting member 10 in the second embodiment.
Furthermore, like the coaxial cable connecting member 10 in the fourth embodiment, the diameter (inner diameter) of the through hole 12 may be set to a plurality.
　また、第１の実施の形態から第６の実施の形態における同軸ケーブル接続部材１０は、貫通孔１２又は保持溝１２′をそれぞれ１個備え、１本の同軸ケーブル３０を接続したが、同軸ケーブル接続部材１０を複数並列させて、複数の同軸ケーブル３０が接続されるようにしてもよい。
　なお、第１の実施の形態及び第６の実施の形態で示した数値は、一例であって、これらに限定されないことは明らかである。
　その他、本発明の趣旨に反しない限りにおいて様々な変形例の組み合わせを行っても構わない。 Further, the coaxial cable connecting member 10 in the first to sixth embodiments includes one through hole 12 or one holding groove 12 ', and one coaxial cable 30 is connected. A plurality of connection members 10 may be arranged in parallel so that a plurality of coaxial cables 30 are connected.
