Description

【0001】
【発明の属する技術分野】
本発明は、組み立てが容易であるとともにインピーダンス特性が安定した同軸コネクタに関するものである。
【0002】
【従来の技術】
携帯通信機器の構成部品として、レセプタクルに接続分離自在な小型の同軸コネクタが汎用されている。かかる小型の同軸コネクタの一例が、特許第3120692号で提案されている。この技術は、同軸コネクタの外部導体を一枚の金属板から打ち抜きおよび折り曲げ加工し、組み立ての際にさらに折り曲げて最終的な形状を形成するものである。
【0003】
【発明が解決しようとする課題】
上記従来の技術にあっては、組み立ての際に折り曲げ加工を必要とし、その作業が煩雑である。しかも、折り曲げ加工された形状の寸法精度が必ずしも安定しておらず、接合されるべき部分に隙間が生ずる虞があり、同軸コネクタのインピーダンス特性が安定しないという不具合がある。
【0004】
本発明は、上述の従来技術の事情に鑑みてなされたもので、組み立てが簡単でしかもインピーダンス特性が安定した同軸コネクタを提供することも目的とする。
【0005】
【課題を解決するための手段】
かかる目的を達成するために本発明の同軸コネクタは、レセプタクルの中心導体に接触する導電体からなるソケットに剥き出しとされた同軸ケーブルの芯線を固定するとともに電気的接続し、2つの分割体をヒンジ結合した形状で金型による樹脂成型品の誘電部材で前記芯線および前記ソケットを挟んで前記芯線と前記ソケットの挿入方向を除く全周を囲み、前記挟んだ状態の誘電部材の外周に係止突部を設け、前記レセプタクルの外部導体に略筒状の縁部が嵌合接触する導電体からなるキャップ状のプレス成型品のハウジングに前記挟んだ状態の誘電部材を挿入嵌合して前記誘電部材を前記挿入方向を除いてほぼ全周を囲み、前記ハウジングに前記誘電部材を挿入嵌合した状態で前記係止突部に臨んで係止孔を穿設して、前記係止孔に前記係止突部を挿入係止させ、しかも前記ハウジングから前記同軸ケーブルが延びる方向に設けた圧着部で前記同軸ケーブルの外部導体をカシメて把持固定するように構成されている。
【0006】
【発明の実施の形態】
以下、本発明の一実施例を、図1ないし図7を参照して説明する。図1は、芯線が剥き出しとされた同軸ケーブルに金属チューブを挿入する図である。図2は、剥き出しとされた芯線をソケットに半田付けして誘電部材に挿入する図である。図3は、芯線とソケットを誘電部材で挟みハウジングに挿入嵌合する図である。図4は、誘電部材をハウジングに挿入嵌合して圧着部をカシメて同軸コネクタを組み立てた図である。図5は、組み立てられた本発明の同軸コネクタの縦断面図である。図6は、本発明の同軸コネクタをレセプタクルに接続しようとする図である。図7は、本発明の同軸コネクタがレセプタクルに接続された図である。
【0007】
まず、図1のごとく同軸ケーブル10の外部導体10aおよび芯線10bを剥き出し状態とし、芯線10bを覆う誘電体10cと外部導体10aの間に金属チューブ12を挿入する。
【0008】
そして、図2のごとく、レセプタクルの中心導体32(図6参照)に接触して電気的接続される導電体からなるソケット14に、芯線10bが半田付け16されて固定されるとともに電気的接続される。また、半田付け16された芯線10bとソケット14が、2つの分割体18a,18bがヒンジ結合18cされた誘電部材18の一方の凹部18dに挿入されて組み込まれる。この誘電部材18の凹部18d,18dは、ソケット14と芯線10bが半田付け16された形状が2分割された凹状とされ、誘電部材18の2つの分割体18a,18bで挟み込むことで、ソケット14をレセプタクル30に挿入する部分を除いて、ソケット14と芯線10bの全周囲が囲まれる。この誘電部材18の2つの分割体18a,18bで挟み込んだ状態が、図3に示される。ここで、挟み込んだ状態の誘電部材18は偏平な略円柱状であり、その外周面に係止突部18eが突設される。
【0009】
さらに、図3のごとく、導電材からなるキャップ状のハウジング20に、誘電部材18が挿入嵌合される。ハウジング20の略筒状の縁部20aに、スリットが設けられて径方向に弾性変形可能であり、レセプタクル30の円筒状の外部導体34に嵌合接続が可能である。また、ハウジング20には、誘電部材18が挿入嵌合された状態で係止突部18eに臨んで係止孔20bが穿設され、係止孔20bに係合突部18eが挿入係止されて、ハウジング20から誘電部材18の抜けが阻止される。さらに、ハウジング20には、同軸ケーブル10が延びる方向に圧着部20cが一体的に設けられる。
【0010】
なお、誘電部材18は、金型による樹脂成型品であり、所定の形状のものが安価に量産し得る。また、ハウジング18は、プレス成型品であり、同様に安価に量産できる。
【0011】
そしてまた、図3のごとく、誘電部材18をハウジング20に挿入嵌合し、さらに図4のごとく、圧着部20cをカシメて外部導体10aおよび同軸ケーブル10の外皮を把持固定する。もって、本発明の同軸コネクタ22が構成される。
【0012】
この発明の同軸コネクタ22は、図5に縦断面で示すごとく、芯線10bとソケット14の挿入方向を除く全周が誘電部材18に囲まれ、しかもこの誘電部材18が挿入方向を除いてほぼ全周がハウジング20で囲まれる。そこで、ほぼ完全な同軸構造が形成されている。そして、誘電部材18およびハウジング20は成型品で形成でき、その形状が安定していて、同軸コネクタ22のインピーダンス特性はバラツキを生じず安定している。また、組み立ては、半田付け16された芯線10bとソケット14を誘電部材18で挟み、これをハウジング20に挿入嵌合させ、さらに圧着部20cをカシメるだけで良く、その作業は簡単である。
【0013】
かかる構成からなる本発明の同軸コネクタ22は、図6に示すごとく、レセプタクル30に組み付けて、図7のごとき状態とすることで、レセプタクル30の中心導体32と同軸ケーブル10の芯線10bが電気的接続され、またレセプタクル30の外部導体34が同軸ケーブル10の外部導体10aに電気的接続され、同軸構造で接続がなされる。
【0014】
なお、上記実施例では、ソケット14に芯線10bを半田付け16しているが、これに限られず、固定と電気的接続がなされるならば、いかなる構造で接合されても良い。また、誘電部材18の2つの分割体18a,18bがヒンジ結合18cされれば良く、ヒンジ結合18cが設けられる位置は上記実施例に限られるものでない。
【0015】
【発明の効果】
上記に説明したように本発明の同軸コネクタは構成されているので、以下のごとき格別な効果を奏する。
【0016】
請求項1記載の同軸コネクタにあっては、組み立てが簡単である。しかも、組み立てられた状態での誘電部材およびハウジングの形状が一定であり、同軸コネクタのインピーダンス特性が安定している。また、係止突部と係止孔により、簡単な構造でハウジングに挿入嵌合された誘電部材の抜けを阻止できる。もって、量産に好適である。

BACKGROUND OF THE INVENTION
The present invention relates to a coaxial connector that is easy to assemble and has stable impedance characteristics.
[0002]
[Prior art]
As a component part of a portable communication device, a small-sized coaxial connector that can be connected to and separated from a receptacle is widely used. An example of such a small coaxial connector is proposed in Japanese Patent No. 3120692. In this technique, an outer conductor of a coaxial connector is punched and bent from a single metal plate, and further bent during assembly to form a final shape.
[0003]
[Problems to be solved by the invention]
In the above-described conventional technology, bending work is required at the time of assembly, and the work is complicated. In addition, the dimensional accuracy of the bent shape is not necessarily stable, and there is a possibility that a gap may be formed in a portion to be joined, and there is a problem that the impedance characteristic of the coaxial connector is not stable.
[0004]
The present invention has been made in view of the above-described prior art, and an object thereof is to provide a coaxial connector that is easy to assemble and has stable impedance characteristics.
[0005]

Surrounding the entire circumference except for the insertion direction of the core wire and the socket by sandwiching the core wire and the socket with a dielectric member of a resin molded product with a mold in a combined shape, and locking protrusions on the outer periphery of the sandwiched dielectric member A dielectric member in a state of being sandwiched in a cap-shaped press-molded product housing made of a conductor having a substantially cylindrical edge fitted and contacted with the outer conductor of the receptacle. , Substantially surrounding the entire circumference except for the insertion direction, and with the dielectric member inserted and fitted into the housing, a locking hole is formed facing the locking projection, and the locking hole is provided with the locking hole. The stop projection was inserted and locked, moreover and a said housing to grip secure the outer conductor by crimping of the coaxial cable crimping portion provided at the direction in which the coaxial cable extends.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram in which a metal tube is inserted into a coaxial cable with a core wire exposed. FIG. 2 is a diagram showing the exposed core wire soldered to a socket and inserted into a dielectric member. FIG. 3 is a diagram showing a core wire and a socket sandwiched between dielectric members and inserted into a housing. FIG. 4 is a view of the coaxial connector assembled by inserting and fitting the dielectric member into the housing and crimping the crimping portion. FIG. 5 is a longitudinal sectional view of the assembled coaxial connector of the present invention. FIG. 6 is a view of connecting the coaxial connector of the present invention to a receptacle. FIG. 7 shows the coaxial connector of the present invention connected to a receptacle.
[0007]
First, as shown in FIG. 1, the outer conductor 10a and the core wire 10b of the coaxial cable 10 are exposed, and the metal tube 12 is inserted between the dielectric 10c covering the core wire 10b and the outer conductor 10a.
[0008]
Then, as shown in FIG. 2, the core wire 10b is soldered and fixed to the socket 14 made of a conductor that is in contact with and electrically connected to the central conductor 32 (see FIG. 6) of the receptacle, and is electrically connected. The Also, the soldered core wire 10b and the socket 14 are inserted and incorporated into one recess 18d of the dielectric member 18 in which the two divided bodies 18a and 18b are hinge-coupled 18c. The concave portions 18d and 18d of the dielectric member 18 are formed into a concave shape in which the shape of the socket 14 and the core wire 10b soldered 16 is divided into two, and the socket 14 is sandwiched between the two divided bodies 18a and 18b of the dielectric member 18. The entire periphery of the socket 14 and the core wire 10b is surrounded except for the portion to be inserted into the receptacle 30. FIG. 3 shows a state where the dielectric member 18 is sandwiched between the two divided bodies 18a and 18b. Here, the sandwiched dielectric member 18 has a flat and substantially cylindrical shape, and a locking projection 18e is provided on the outer peripheral surface thereof.
[0009]
Further, as shown in FIG. 3, the dielectric member 18 is inserted and fitted into a cap-shaped housing 20 made of a conductive material. The substantially cylindrical edge 20a of the housing 20 is provided with a slit so as to be elastically deformable in the radial direction, and can be fitted and connected to the cylindrical outer conductor 34 of the receptacle 30. In addition, the housing 20 is provided with a locking hole 20b facing the locking protrusion 18e in a state where the dielectric member 18 is inserted and fitted, and the engaging protrusion 18e is inserted and locked in the locking hole 20b. Thus, the dielectric member 18 is prevented from coming off from the housing 20. Furthermore, the housing 20 is integrally provided with a crimping portion 20c in the direction in which the coaxial cable 10 extends.
[0010]
The dielectric member 18 is a resin molded product using a mold, and a predetermined shape can be mass-produced at low cost. The housing 18 is a press-molded product, and can be mass-produced at a low cost.
[0011]
Further, as shown in FIG. 3, the dielectric member 18 is inserted and fitted into the housing 20, and as shown in FIG. 4, the crimping portion 20c is crimped to grip and fix the outer conductor 10a and the outer sheath of the coaxial cable 10. Thus, the coaxial connector 22 of the present invention is configured.
[0012]
As shown in a longitudinal section in FIG. 5, the coaxial connector 22 of the present invention is surrounded by the dielectric member 18 except for the insertion direction of the core wire 10b and the socket 14, and the dielectric member 18 is substantially entirely excluding the insertion direction. The circumference is surrounded by the housing 20. Thus, a nearly complete coaxial structure is formed. The dielectric member 18 and the housing 20 can be formed of molded products, the shapes thereof are stable, and the impedance characteristics of the coaxial connector 22 are stable without variation. In addition, the assembly can be performed simply by sandwiching the soldered core wire 10b and the socket 14 with the dielectric member 18, inserting and fitting them into the housing 20, and further crimping the crimping portion 20c.
[0013]
As shown in FIG. 6, the coaxial connector 22 of the present invention having such a configuration is assembled to the receptacle 30 so as to be in a state as shown in FIG. 7, whereby the central conductor 32 of the receptacle 30 and the core wire 10 b of the coaxial cable 10 are electrically connected. In addition, the outer conductor 34 of the receptacle 30 is electrically connected to the outer conductor 10a of the coaxial cable 10 and is connected in a coaxial structure.
[0014]
In the above embodiment, the core wire 10b is soldered 16 to the socket 14. However, the present invention is not limited to this, and any structure may be used as long as it is fixed and electrically connected. Further, the two divided members 18a and 18b of the dielectric member 18 only need to be hinge-coupled 18c, and the position where the hinge joint 18c is provided is not limited to the above embodiment.
[0015]
【The invention's effect】
As described above, since the coaxial connector of the present invention is configured, the following special effects can be obtained.
[0016]
The coaxial connector according to claim 1 is easy to assemble. Moreover, the shape of the dielectric member and the housing in the assembled state is constant, and the impedance characteristic of the coaxial connector is stable. Further, the locking protrusion and the locking hole can prevent the dielectric member inserted and fitted in the housing with a simple structure from being pulled out. Therefore, it is suitable for mass production.
