Description

本発明は、同軸ケーブル接続端子に関し、特に基板に直接接続する同軸ケーブル接続端子に関する。   The present invention relates to a coaxial cable connection terminal, and more particularly to a coaxial cable connection terminal that is directly connected to a substrate.

同軸ケーブルは、アンテナ素子等の信号用配線として広く用いられている。同軸ケーブルの構造は、図１に示すように、信号を伝送するための芯線１と、芯線１を覆う内部絶縁体２と、細い銅線を編み込んだ編組線３と、保護被覆４とを備えている。編組線３は一般にアースに接続される。   Coaxial cables are widely used as signal wiring for antenna elements and the like. As shown in FIG. 1, the structure of the coaxial cable includes a core wire 1 for transmitting a signal, an internal insulator 2 covering the core wire 1, a braided wire 3 knitted with a thin copper wire, and a protective coating 4. ing. The braided wire 3 is generally connected to ground.

同軸ケーブルの一方の端部はアンテナ等の素子に接続され、他方の端部は電子回路基板等に接続される。同軸ケーブルをアンテナ素子に接続する場合にはアンテナアンプを介して接続する。同軸ケーブルを、アンテナアンプを構成する基板（以下、「基板」という。）に接続する方法として種々の方法が知られている。図２に、同軸ケーブルを基板に直付けする方法を示す。同軸ケーブル１０の芯線１は、基板５の芯線接続部１０１と半田付けにより電気的に接続される。一方、編組線３は、編み込んだ銅線をほぐして所定の長さを確保したうえで基板５の編組線接続部１０２、１０３と半田付けにより電気的に接続される。   One end of the coaxial cable is connected to an element such as an antenna, and the other end is connected to an electronic circuit board or the like. When the coaxial cable is connected to the antenna element, it is connected via an antenna amplifier. Various methods are known as a method of connecting a coaxial cable to a substrate (hereinafter referred to as “substrate”) constituting an antenna amplifier. FIG. 2 shows a method of directly attaching the coaxial cable to the substrate. The core wire 1 of the coaxial cable 10 is electrically connected to the core wire connecting portion 101 of the substrate 5 by soldering. On the other hand, the braided wire 3 is electrically connected to the braided wire connecting portions 102 and 103 of the substrate 5 by soldering after loosening the braided copper wire to ensure a predetermined length.

また、基板側と同軸ケーブル側とをコネクタを介して接続する方法も知られている。図３に、コネクタを用いた接続方法を示す。同軸ケーブル１０の端部にはコネクタ１０５が接続されており、基板５には配線１０６を介してコネクタ接続部１０４が設けられている。コネクタ１０５をコネクタ接続部１０４に接続することによって、同軸ケーブル１０と基板５との電気的な接続を行うことができる。   A method of connecting the substrate side and the coaxial cable side via a connector is also known. FIG. 3 shows a connection method using a connector. A connector 105 is connected to an end portion of the coaxial cable 10, and a connector connecting portion 104 is provided on the substrate 5 via a wiring 106. By connecting the connector 105 to the connector connecting portion 104, the coaxial cable 10 and the substrate 5 can be electrically connected.

一方、ガラス基板上に設けたアンテナパターンに同軸ケーブルを接続する方法として、コネクタを用いる方法が知られている（例えば、特許文献１）。   On the other hand, as a method for connecting a coaxial cable to an antenna pattern provided on a glass substrate, a method using a connector is known (for example, Patent Document 1).

実公平８−２９２６Reality 8-2926

図４に示すように、車両のフロントガラス１１０に設けたフィルムアンテナ１１１に、同軸ケーブル１０を繋いだアンテナアンプ１００を接続する場合、ドライバーの視界を妨げないようにアンテナアンプの小型化が要求される。したがって、同軸ケーブル接続端子をアンテナアンプに用いる場合には、アンテナアンプの小型化に伴い接続部の小型化、即ち、アンテナアンプを構成する基板に占める面積を縮小することが望まれている。このような状況のもとで従来の同軸ケーブルの接続方法について検討すると、同軸ケーブルを基板に直付けする方法では、設置場所のフロントガラス１１０は曲面を有しており、応力がかかるため、同軸ケーブル１０の保護被覆４が引っ張られたときのストレスが、半田付けをした芯線接続部１０１及び編組線接続部１０２、１０３に直接加わり、半田付けをした部分にクラックが生じ断線する恐れがある。さらに、芯線接続部１０１と、編組線接続部１０２、１０３の位置決めを高精度に行うことが困難であり、接続部の小型化を行うことが困難であった。また、アンテナ素子（アンテナエレメント）は、通常フロントガラスの端の方に設置されるため設置自由度が低く、半田付けによって接続した場合においては位置決めを高精度に行うことが困難であった。   As shown in FIG. 4, when the antenna amplifier 100 connected to the coaxial cable 10 is connected to the film antenna 111 provided on the windshield 110 of the vehicle, it is required to reduce the size of the antenna amplifier so as not to disturb the driver's view. The Therefore, when the coaxial cable connection terminal is used for the antenna amplifier, it is desired to reduce the size of the connection portion, that is, to reduce the area occupied by the substrate constituting the antenna amplifier as the antenna amplifier is downsized. Considering a conventional method of connecting a coaxial cable under such circumstances, in the method of directly attaching the coaxial cable to the substrate, the windshield 110 at the installation location has a curved surface and stress is applied. The stress when the protective coating 4 of the cable 10 is pulled is directly applied to the soldered core wire connecting portion 101 and the braided wire connecting portions 102 and 103, and there is a risk that the soldered portion will crack and break. Furthermore, it is difficult to position the core wire connecting portion 101 and the braided wire connecting portions 102 and 103 with high accuracy, and it is difficult to reduce the size of the connecting portion. Further, since the antenna element (antenna element) is usually installed toward the end of the windshield, the degree of freedom of installation is low, and it is difficult to perform positioning with high precision when connected by soldering.

一方、コネクタを用いる方法では、コネクタ及びコネクタ接続部にある程度のサイズが必要となり、接続部の小型化を行うことが困難であった。また、コネクタを製造するためのコストにより、基板と同軸ケーブルとの接続部のコストが上昇するという問題も生じていた。   On the other hand, in the method using a connector, a certain size is required for the connector and the connector connecting portion, and it is difficult to reduce the size of the connecting portion. In addition, the cost for manufacturing the connector also raises a problem that the cost of the connecting portion between the substrate and the coaxial cable increases.

本発明は、上記のような問題点に鑑み、同軸ケーブルと基板との接続部を小型化することが可能な同軸ケーブル接続端子を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a coaxial cable connection terminal capable of reducing the size of a connection portion between a coaxial cable and a substrate.

本発明の同軸ケーブル接続端子は、同軸ケーブルと基板とを電気的に接続するための接続端子であって、同軸ケーブルの芯線と接続するための芯線接続部と、基板と電気的に接続するための第１接続端子と、芯線接続部と第１接続端子に接続されている内導体本体部と、を備えた内導体と、同軸ケーブルの編組線と接続するための編組線接続部と、基板と電気的に接続するための第２接続端子と、編組線接続部と第２接続端子に接続されている外導体本体部と、を備えた外導体と、内導体本体部と外導体本体部との間に設けられて、内導体と外導体との間を電気的に絶縁するとともに、内導体本体部と外導体本体部とを位置決めするホルダと、を有することを特徴とする。   The coaxial cable connection terminal of the present invention is a connection terminal for electrically connecting the coaxial cable and the substrate, and for electrically connecting the core wire connection portion for connecting to the core wire of the coaxial cable and the substrate. An inner conductor having a first connecting terminal, a core wire connecting portion and an inner conductor main body connected to the first connecting terminal, a braided wire connecting portion for connecting to a braided wire of a coaxial cable, and a substrate An outer conductor comprising: a second connection terminal for electrically connecting to the wire; a braided wire connection portion; and an outer conductor body portion connected to the second connection terminal; an inner conductor body portion and an outer conductor body portion; And a holder for electrically insulating the inner conductor and the outer conductor and positioning the inner conductor main body portion and the outer conductor main body portion.

本発明の同軸ケーブル接続端子は、同軸ケーブルの芯線と接続する内導体と、編組線と接続する外導体とを備えており、これらを用いて基板との接続を行っているので、同軸ケーブルと基板との接続部を小型化することができる。   The coaxial cable connection terminal of the present invention includes an inner conductor that is connected to the core wire of the coaxial cable and an outer conductor that is connected to the braided wire. Since these are used to connect to the substrate, the coaxial cable and A connection part with a board | substrate can be reduced in size.

以下、図面を参照して、本発明に係る同軸ケーブル接続端子について説明する。ただし、本発明の技術的範囲はそれらの実施の形態には限定されず、特許請求の範囲に記載された発明とその均等物に及ぶ点に留意されたい。   Hereinafter, a coaxial cable connection terminal according to the present invention will be described with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and equivalents thereof.

本発明の第１の実施例に係る同軸ケーブル接続端子の構造を図１４（ａ）に示す。本発明の同軸ケーブル接続端子は、図１６（ｂ）に示すように、車両のフロントガラスに設けられたフィルムアンテナに接続されるアンテナアンプ（図４）を構成する基板５に、同軸ケーブル１０を接続する際に用いるものである。本発明の同軸ケーブル接続端子は、同軸ケーブル１０と基板との間で電気的な接続を行うための接続端子であって、同軸ケーブル１０の芯線と接続するための芯線接続部６１と、基板と電気的に接続するための第１接続端子６２と、芯線接続部６１と第１接続端子６２に接続されている内導体本体部と、を備えた内導体６と、同軸ケーブル１０の編組線と接続するための編組線接続部８１と、基板と電気的に接続するための第２接続端子８３と、編組線接続部８１と第２接続端子８３に接続されている外導体本体部と、を備えた外導体８と、内導体本体部と外導体本体部との間に設けられて、内導体６と外導体８との間を電気的に絶縁するとともに、内導体本体部と外導体本体部とを位置決めするホルダ７と、を有する。第１接続端子６２は同軸ケーブル１０の芯線と接続され、第２接続端子８３は編組線と接続されているため、第１接続端子６２から芯線に流れる信号を取り出すことができ、第２接続端子８３を接地することによって編組線を接地することができる。   FIG. 14A shows the structure of the coaxial cable connection terminal according to the first embodiment of the present invention. As shown in FIG. 16 (b), the coaxial cable connection terminal of the present invention has a coaxial cable 10 on a substrate 5 constituting an antenna amplifier (FIG. 4) connected to a film antenna provided on a windshield of a vehicle. It is used when connecting. The coaxial cable connection terminal of the present invention is a connection terminal for making an electrical connection between the coaxial cable 10 and the substrate, the core wire connection portion 61 for connecting to the core wire of the coaxial cable 10, the substrate, An inner conductor 6 including a first connection terminal 62 for electrical connection, a core wire connection portion 61 and an inner conductor main body portion connected to the first connection terminal 62, and a braided wire of the coaxial cable 10; A braided wire connection part 81 for connection, a second connection terminal 83 for electrical connection with the substrate, and an outer conductor main body part connected to the braided wire connection part 81 and the second connection terminal 83; Provided between the outer conductor 8 provided, the inner conductor main body portion and the outer conductor main body portion to electrically insulate between the inner conductor 6 and the outer conductor 8, and the inner conductor main body portion and the outer conductor main body. And a holder 7 for positioning the part. Since the first connection terminal 62 is connected to the core wire of the coaxial cable 10 and the second connection terminal 83 is connected to the braided wire, a signal flowing from the first connection terminal 62 to the core wire can be taken out. The braided wire can be grounded by grounding 83.

次に、本発明の第１の実施例に係る同軸ケーブル接続端子を構成する各部材の構造について、同軸ケーブルへの接続方法とともに説明する。図５は本発明の実施例１の同軸ケーブル接続端子を構成する内導体の斜視図を示し、同図（ａ）は表側から見た斜視図を示し、同図（ｂ）は裏側から見た斜視図を示す。図５に示すように、内導体６は、同軸ケーブルの芯線と接続するための芯線接続部６１と、基板と電気的に接続するための第１接続端子６２と、芯線接続部６１と第１接続端子６２に電気的に接続されている内導体本体部６４と、を備えている。このような構成により、内導体６はアンテナエレメントで受信した信号を同軸ケーブルへ送ることが可能となる。内導体６は、金属等の良導体で構成されていることが好ましく、さらには加締めることが容易な材質で構成されることがより好ましい。   Next, the structure of each member constituting the coaxial cable connection terminal according to the first embodiment of the present invention will be described together with a method for connecting to the coaxial cable. 5 shows a perspective view of the inner conductor constituting the coaxial cable connection terminal of Example 1 of the present invention, FIG. 5 (a) shows a perspective view seen from the front side, and FIG. 5 (b) seen from the back side. A perspective view is shown. As shown in FIG. 5, the inner conductor 6 includes a core wire connection portion 61 for connecting to the core wire of the coaxial cable, a first connection terminal 62 for electrically connecting to the substrate, a core wire connection portion 61 and a first wire. And an inner conductor main body portion 64 electrically connected to the connection terminal 62. With such a configuration, the inner conductor 6 can send a signal received by the antenna element to the coaxial cable. The inner conductor 6 is preferably made of a good conductor such as metal, and more preferably made of a material that can be easily crimped.

芯線接続部６１は筒状の形状を有しており、芯線を挿通させるために芯線の直径よりも大きな空洞を有している。本実施例では、筒状の形状を有している例を示したが、後述するように外導体同様、芯線を挿通させる前は開放した状態となっていてもよい。内導体本体部６４は、後述するホルダと組み合わせるために平坦部を備えていることが好ましい。第１接続端子６２を設ける位置は用途に応じて自由に選択することができる。内導体を用いない場合は、芯線と導通を取るための接続箇所が、芯線が配置された同軸ケーブルの中心線上に制限されていたが、内導体を用いることで芯線との接続箇所を自由に配置することができ、従来に比べて配置の自由度が増すという効果が得られる。このため、基板上のスペース効率が向上し、接続部の長さ方向、幅方向で小型化を実現することができる。また、第１接続端子６２は基板に装着する作業を容易とするために鉛直方向に垂下した短冊状の形状とすることが好ましい。さらに、内導体６の幅ｄ1を短縮するためには、図５（ａ）に示すように、第１接続端子６２を構成する平面部が、芯線接続部６１の長手方向と水平となるように構成することが好ましい。一方、同軸ケーブルの引張りによるストレスを緩和するために、第１接続端子６２を構成する平面部を芯線接続部６１の長手方向と直交するように構成してもよい。 The core wire connecting portion 61 has a cylindrical shape, and has a cavity larger than the diameter of the core wire in order to insert the core wire. In the present embodiment, an example having a cylindrical shape is shown, but as described later, it may be in an open state before the core wire is inserted, as in the case of the outer conductor. The inner conductor main body portion 64 preferably includes a flat portion in order to be combined with a holder described later. The position where the first connection terminal 62 is provided can be freely selected according to the application. When the inner conductor is not used, the connection location for conducting with the core wire is limited to the center line of the coaxial cable on which the core wire is arranged, but the connection location with the core wire can be freely set by using the inner conductor. It can arrange | position and the effect that the freedom degree of arrangement | positioning increases compared with the past is acquired. For this reason, the space efficiency on a board | substrate improves and size reduction can be implement | achieved in the length direction of the connection part, and the width direction. Further, the first connection terminal 62 is preferably formed in a strip shape that hangs down in the vertical direction in order to facilitate the work of mounting on the substrate. Furthermore, in order to shorten the width d 1 of the inner conductor 6, the plane portion constituting the first connection terminal 62 is horizontal with the longitudinal direction of the core wire connection portion 61 as shown in FIG. It is preferable to configure. On the other hand, in order to relieve stress due to the pulling of the coaxial cable, the plane portion constituting the first connection terminal 62 may be configured to be orthogonal to the longitudinal direction of the core wire connection portion 61.

また、内導体６は、後述するホルダと嵌合するためのホルダ固定部６３ａ、６３ｂをさらに備えていてもよい。ホルダ固定部６３ａ、６３ｂは、図５（ａ）、（ｂ）に示すように、ホルダ固定部６３ａ、６３ｂを構成する平面部が、芯線接続部６１の長手方向と水平となるように構成することが好ましい。   Further, the inner conductor 6 may further include holder fixing portions 63a and 63b for fitting with a holder described later. As shown in FIGS. 5A and 5B, the holder fixing portions 63 a and 63 b are configured such that the flat portions constituting the holder fixing portions 63 a and 63 b are horizontal with the longitudinal direction of the core wire connecting portion 61. It is preferable.

次に、内導体６と同軸ケーブル１０との接続方法について説明する。図６に内導体の同軸ケーブルへの接続方法を示す。同軸ケーブル１０及び内導体６の芯線接続部６１のそれぞれの中心線を同一直線上に配置した上で、同軸ケーブル１０の芯線１に芯線接続部６１の空洞部分を挿通させる。内導体６を同軸ケーブル１０の芯線１に挿通した後の状態を図７（ａ）、（ｂ）に示す。同図（ａ）は表側から見た斜視図を示し、同図（ｂ）は裏側から見た斜視図を示す。芯線接続部６１の内径は内部絶縁体２の外径よりも小さいため、芯線接続部６１の先端部が内部絶縁体２の端部を乗り越えることはなく、芯線接続部６１が編組線３と接触することはない。芯線接続部６１に芯線１を挿通させた後、芯線接続部６１を加締めることにより、内導体６と芯線１とが電気的に接続される。   Next, a method for connecting the inner conductor 6 and the coaxial cable 10 will be described. FIG. 6 shows a method for connecting the inner conductor to the coaxial cable. After the center lines of the coaxial cable 10 and the core wire connection portion 61 of the inner conductor 6 are arranged on the same straight line, the hollow portion of the core wire connection portion 61 is inserted into the core wire 1 of the coaxial cable 10. A state after the inner conductor 6 is inserted through the core wire 1 of the coaxial cable 10 is shown in FIGS. The figure (a) shows the perspective view seen from the front side, and the figure (b) shows the perspective view seen from the back side. Since the inner diameter of the core wire connecting portion 61 is smaller than the outer diameter of the inner insulator 2, the tip end portion of the core wire connecting portion 61 does not get over the end portion of the inner insulator 2, and the core wire connecting portion 61 contacts the braided wire 3. Never do. After the core wire 1 is inserted through the core wire connection portion 61, the inner conductor 6 and the core wire 1 are electrically connected by crimping the core wire connection portion 61.

次に、ホルダの構造について説明する。図８はホルダの斜視図であり、同図（ａ）は表側から見た斜視図を示し、同図（ｂ）は裏側から見た斜視図を示す。ホルダ７は、ホルダ本体表面部７２とホルダ本体裏面部７３とを有し、それぞれ外導体及び内導体と接合する。また、ホルダ７は、内導体６のホルダ固定部６３ａ、６３ｂ（図５（ｂ））と嵌合するように第１凹部７４ａ、７４ｂとツメ７５ａ、７５ｂとを有している。さらに、後述するように、外導体８の基板固定部８４ａ、８４ｂ（図１２（ａ））と嵌合する第２凹部７１ａ、７１ｂとツメ７６ａ、７６ｂとを有している。ホルダ７は、絶縁性を備えており、外部から作用する力に対して一定の強度を有していることが好ましく、例えば樹脂等で構成することが好ましい。   Next, the structure of the holder will be described. FIG. 8 is a perspective view of the holder. FIG. 8A shows a perspective view seen from the front side, and FIG. 8B shows a perspective view seen from the back side. The holder 7 has a holder main body surface portion 72 and a holder main body back surface portion 73, and is joined to the outer conductor and the inner conductor, respectively. Moreover, the holder 7 has 1st recessed parts 74a and 74b and claws 75a and 75b so that it may fit with the holder fixing | fixed part 63a, 63b (FIG.5 (b)) of the inner conductor 6. FIG. Furthermore, as will be described later, there are second recesses 71a, 71b and claws 76a, 76b that fit into the board fixing portions 84a, 84b (FIG. 12A) of the outer conductor 8. The holder 7 is provided with an insulating property and preferably has a certain strength against a force acting from the outside. For example, the holder 7 is preferably made of a resin or the like.

次に、ホルダの内導体への装着方法について説明する。図９は、ホルダの内導体への装着方法を示す斜視図である。内導体６を同軸ケーブル１０に接続し、内導体６の内導体本体部６４の平面部を水平に保持した状態で、内導体６の上方からホルダ７を嵌合させる。このとき、内導体６のホルダ固定部６３ａ、６３ｂ（図５（ｂ））をホルダ７の第１凹部７４ａ、７４ｂ（図８（ｂ））に嵌合させる。ここで、内導体６のホルダ７への嵌合は、ホルダ７に設けたツメ７５ａ、７５ｂ（図８（ｂ））を用いて内導体６を保持することにより行う。また、内導体本体部６４の平面部とホルダとの間に接着剤を塗布することにより、内導体とホルダとを接着してもよい。   Next, a method for attaching the holder to the inner conductor will be described. FIG. 9 is a perspective view showing a method of attaching the holder to the inner conductor. The inner conductor 6 is connected to the coaxial cable 10, and the holder 7 is fitted from above the inner conductor 6 in a state where the flat portion of the inner conductor main body 64 of the inner conductor 6 is held horizontally. At this time, the holder fixing portions 63 a and 63 b (FIG. 5B) of the inner conductor 6 are fitted into the first recesses 74 a and 74 b (FIG. 8B) of the holder 7. Here, the fitting of the inner conductor 6 to the holder 7 is performed by holding the inner conductor 6 using the claws 75 a and 75 b (FIG. 8B) provided on the holder 7. Moreover, you may adhere | attach an inner conductor and a holder by apply | coating an adhesive agent between the plane part of the inner conductor main-body part 64, and a holder.

上記のようにして、ホルダを内導体に装着した状態を図１０に示す。同図（ａ）は表側から見た斜視図を示し、同図（ｂ）は裏側から見た斜視図を示す。同図（ｂ）に示すように、内導体６のホルダ固定部６３ａ、６３ｂが、ホルダ７の第１凹部７４ａ、７４ｂに嵌合している。図１０（ｂ）のＩ−Ｉでの断面図を図１１に示す。内導体６のホルダ固定部６３ａ、６３ｂは、ホルダ７のツメ７５ａ、７５ｂによって保持される。このような構成とすることによって、ホルダを内導体に固定することができ、ホルダを内導体に位置決めすることができる。さらに、内導体６の芯線接続部６１がホルダ７によって覆われるので、後述する外導体との間の短絡を防止することができる。   FIG. 10 shows a state in which the holder is attached to the inner conductor as described above. The figure (a) shows the perspective view seen from the front side, and the figure (b) shows the perspective view seen from the back side. As shown in FIG. 4B, the holder fixing portions 63 a and 63 b of the inner conductor 6 are fitted in the first recesses 74 a and 74 b of the holder 7. A cross-sectional view taken along line II of FIG. 10B is shown in FIG. The holder fixing portions 63 a and 63 b of the inner conductor 6 are held by the claws 75 a and 75 b of the holder 7. By setting it as such a structure, a holder can be fixed to an inner conductor and a holder can be positioned to an inner conductor. Furthermore, since the core wire connecting portion 61 of the inner conductor 6 is covered by the holder 7, a short circuit with the outer conductor described later can be prevented.

次に、外導体の構造について説明する。図１２に外導体８の斜視図を示す。同図（ａ）に表側から見た斜視図を示し、同図（ｂ）に裏側から見た斜視図を示す。外導体８は、同軸ケーブルの編組線と接続するための編組線接続部８１と、基板と電気的に接続するための第２接続端子８３と、編組線接続部８１と第２接続端子８３に電気的に接続されている外導体本体部８５とを備えている。さらに、外導体８を基板に固定するための基板固定部８４ａ、８４ｂを有することが好ましい。第２接続端子８３と基板固定部８４ａ、８４ｂは、短冊状の形状を有しており、外導体本体部８５の平面部に対して略垂直方向に垂下している。また、外導体８の幅ｄ2を短縮するためには、図１２（ａ）に示すように、第２接続端子８３を構成する平面部が、編組線接続部８１の長手方向と水平となるように構成することが好ましい。一方、同軸ケーブルの引張りによるストレスを緩和するために、第２接続端子８３を構成する平面部を編組線接続部８の長手方向と直交するように構成してもよい。さらに、外導体８は、同軸ケーブルの保護被覆に固定するための保護被覆保持部８２を備えていることが好ましい。保護被覆保持部８２によって保護被覆を保持することにより、同軸ケーブルが引っ張られるストレスが加わったときに、編組線接続部８１に加わるストレスを緩和することができ、同軸ケーブル接続端子が同軸ケーブルから脱落するのを防止することができる。外導体８は、金属等の良導体で構成されていることが好ましく、さらには加締めることが容易な材質で構成されていることがより好ましい。 Next, the structure of the outer conductor will be described. FIG. 12 is a perspective view of the outer conductor 8. The perspective view seen from the front side is shown to the figure (a), and the perspective view seen from the back side is shown to the figure (b).

The second connection terminal 83 and the board fixing portions 84 a and 84 b have a strip shape and hang in a substantially vertical direction with respect to the flat portion of the outer conductor main body portion 85. Further, in order to shorten the width d 2 of the outer conductor 8, as shown in FIG. 12A, the plane portion constituting the second connection terminal 83 is horizontal with the longitudinal direction of the braided wire connection portion 81. It is preferable to configure as described above. On the other hand, in order to relieve stress due to the tension of the coaxial cable, the plane portion constituting the second connection terminal 83 may be configured to be orthogonal to the longitudinal direction of the braided wire connection portion 8. Furthermore, it is preferable that the outer conductor 8 includes a protective coating holding portion 82 for fixing to the protective coating of the coaxial cable. By holding the protective coating by the protective coating holding portion 82, the stress applied to the braided wire connecting portion 81 can be relieved when a stress is applied to the coaxial cable, and the coaxial cable connection terminal is detached from the coaxial cable. Can be prevented. The outer conductor 8 is preferably made of a good conductor such as metal, and more preferably made of a material that can be easily crimped.

次に、外導体のホルダへの装着方法について図面を用いて説明する。図１３は、同軸ケーブル１０に内導体及びホルダ７を装着した構造に対して、外導体８を装着する方法を示す斜視図である。まず、編組線接続部８１の下部８１ａ及び保護被膜保持部８２の下部８２ａを開放し、編組線３及び保護被膜４が、それぞれ編組線接続部８１及び保護被膜保持部８２に収納されるようにしておく。次に、ホルダ７のホルダ本体表面部７２の上方から外導体８を装着する。このとき、外導体８の基板保持部８４ａ、８４ｂが、ホルダ７の第２凹部７１ａ、７１ｂ（図８（ｂ））に嵌合するように装着する。このとき、外導体８のホルダ７への嵌合は、ホルダ７に設けたツメ７６ａ、７６ｂ及びツメ７６ａ、７６ｂが嵌るように外導体８に設けた穴８６ａ、８６ｂを用いて、外導体８を保持することにより行う。また、ホルダ本体表面部７２と外導体との間に接着剤を塗布して、ホルダと外導体とを接着してもよい。装着後に、編組線接続部８１及び保護被膜保持部８２をそれぞれ編組線３及び保護被膜４に巻きつけた後、加締めることにより編組線接続部８１は編組線３と電気的に接続され、保護被膜保持部８２は保護被膜４に保持される。   Next, a method for attaching the outer conductor to the holder will be described with reference to the drawings. FIG. 13 is a perspective view showing a method of attaching the outer conductor 8 to the structure in which the inner conductor and the holder 7 are attached to the coaxial cable 10. First, the lower part 81a of the braided wire connection part 81 and the lower part 82a of the protective film holding part 82 are opened so that the braided wire 3 and the protective film 4 are accommodated in the braided wire connection part 81 and the protective film holding part 82, respectively. Keep it. Next, the outer conductor 8 is mounted from above the holder body surface portion 72 of the holder 7. At this time, the substrate holding portions 84 a and 84 b of the outer conductor 8 are mounted so as to fit into the second recesses 71 a and 71 b (FIG. 8B) of the holder 7. At this time, the outer conductor 8 is fitted into the holder 7 by using the claws 76a and 76b provided in the holder 7 and the holes 86a and 86b provided in the outer conductor 8 so that the claws 76a and 76b are fitted. This is done by holding Further, an adhesive may be applied between the holder main body surface portion 72 and the outer conductor to bond the holder and the outer conductor. After the mounting, the braided wire connecting portion 81 and the protective coating holding portion 82 are wound around the braided wire 3 and the protective coating 4, respectively, and then caulked to electrically connect the braided wire connecting portion 81 to the braided wire 3 for protection. The film holding part 82 is held by the protective film 4.

このようにして外導体８を装着した後の同軸ケーブル接続部の構造を図１４に示す。同図（ａ）に表側から見た斜視図を示し、同図（ｂ）に裏側から見た斜視図を示す。外導体８の基板保持部８４ａ、８４ｂがホルダ７の第２凹部７１ａ、７１ｂに嵌合しており、外導体８がホルダ７に位置決めされている。さらに、図１４（ａ）のII−IIでの断面図を図１５に示す。ホルダ７に設けたツメ７６ａ、７６ｂが、外導体８に設けた穴８６ａ、８６ｂに嵌め込まれて、外導体８はホルダに保持される。また、図１０（ｂ）及び図１１に示すように内導体６はホルダ７によって位置決めされている。その結果、内導体及び外導体がホルダを介して一体化された構造となる。   FIG. 14 shows the structure of the coaxial cable connecting portion after mounting the outer conductor 8 in this way. The perspective view seen from the front side is shown to the figure (a), and the perspective view seen from the back side is shown to the figure (b). The board holding portions 84 a and 84 b of the outer conductor 8 are fitted in the second recesses 71 a and 71 b of the holder 7, and the outer conductor 8 is positioned on the holder 7. Further, FIG. 15 shows a cross-sectional view taken along line II-II in FIG. The claws 76a and 76b provided in the holder 7 are fitted into the holes 86a and 86b provided in the outer conductor 8, and the outer conductor 8 is held by the holder. Further, as shown in FIGS. 10B and 11, the inner conductor 6 is positioned by the holder 7. As a result, an inner conductor and an outer conductor are integrated through a holder.

次に、同軸ケーブル接続端子の基板への接続方法について説明する。図１６は同軸ケーブル接続端子の基板への接続方法を示す斜視図である。まず、図１６（ａ）に示すように、基板５に内導体の第１接続端子６２を挿通させる第１開口部５１と、外導体の第２接続端子８３を挿通させる第２開口部５２とを設けておく。さらに、外導体に基板固定部８４ａ、８４ｂを形成した場合には、それぞれを挿通させる第３開口部５３ａと第４開口部５３ｂとを設ける。図１６（ａ）の矢印で示すように、基板５に対して垂直方向に同軸ケーブル接続端子を降下させる。このとき、内導体と外導体の位置はホルダによって決められているので、第１接続端子６２、第２接続端子８３及び基板固定部８４ａ、８４ｂを１回の作業で、基板に設けた開口部５１、５２、５３ａ、５３ｂに挿通させることができる。   Next, a method for connecting the coaxial cable connection terminal to the substrate will be described. FIG. 16 is a perspective view showing a method of connecting the coaxial cable connection terminal to the substrate. First, as shown in FIG. 16A, a first opening 51 through which the first connection terminal 62 of the inner conductor is inserted into the substrate 5, and a second opening 52 through which the second connection terminal 83 of the outer conductor is inserted. Is provided. Further, when the substrate fixing portions 84a and 84b are formed in the outer conductor, a third opening 53a and a fourth opening 53b through which each is inserted are provided. As shown by the arrow in FIG. 16A, the coaxial cable connection terminal is lowered in the direction perpendicular to the substrate 5. At this time, since the positions of the inner conductor and the outer conductor are determined by the holder, the first connection terminal 62, the second connection terminal 83, and the board fixing portions 84a and 84b are opened in the board by one operation. 51, 52, 53a, 53b can be inserted.

同軸ケーブル接続端子をさらに降下させると、図１６（ｂ）に示すように、ホルダ７の下端部が基板５に当接し、同軸ケーブル接続端子が基板５に保持される。その後、第１接続端子６２及び第２接続端子８３と、基板５に設けた配線等との間で半田付けにより電気的な接続を行う。一方、基板固定部８４ａ、８４ｂを同軸ケーブルの長手方向に対して直交する方向に折り曲げることによって、同軸ケーブル接続端子を基板に固定することができる。なお、本実施例においては外導体に基板固定部を２つ設けた例を示したが、これには限られず１つでも３つ以上でもよい。また、本実施例においては外導体に基板固定部を設けた例を示したが、基板固定部を内導体に設けてもよく、ホルダに設けてもよい。   When the coaxial cable connection terminal is further lowered, the lower end portion of the holder 7 comes into contact with the substrate 5 and the coaxial cable connection terminal is held by the substrate 5 as shown in FIG. Thereafter, electrical connection is performed by soldering between the first connection terminal 62 and the second connection terminal 83 and the wiring provided on the substrate 5. On the other hand, the coaxial cable connection terminals can be fixed to the substrate by bending the substrate fixing portions 84a and 84b in a direction orthogonal to the longitudinal direction of the coaxial cable. In the present embodiment, an example in which two substrate fixing portions are provided on the outer conductor has been shown, but the present invention is not limited to this and may be one or three or more. Moreover, although the example which provided the board | substrate fixing | fixed part in the outer conductor in the present Example was shown, the board | substrate fixing | fixed part may be provided in an inner conductor and may be provided in a holder.

また、図１６（ａ）、（ｂ）に示すように、第１接続端子６２と、第２接続端子８３とを、同軸ケーブルの長手方向の延長線に関して略対称となるように配置することが好ましい。即ち、図１６（ａ）に示すように、第１接続端子６２と、第２接続端子８３とを、同軸ケーブルの延長線を挟んで、同軸ケーブルの長手方向に対して直交する方向に並べることが好ましい。このように、芯線及び編組線と電気的に接続するための端子を同軸ケーブルに関して対称に配置することによって、同軸ケーブル接続端子の長手方向の長さを短縮することができ、製品の小型化を実現することができる。さらに、基板固定部８４ａ、８４ｂを設けた場合でも電気的に接続するための端子を接続端子の先端部に配置することによって、配線の取り回しを容易にすることができる。   Further, as shown in FIGS. 16A and 16B, the first connection terminal 62 and the second connection terminal 83 may be arranged so as to be substantially symmetric with respect to the extension line in the longitudinal direction of the coaxial cable. preferable. That is, as shown in FIG. 16A, the first connection terminal 62 and the second connection terminal 83 are arranged in a direction orthogonal to the longitudinal direction of the coaxial cable with the extension line of the coaxial cable interposed therebetween. Is preferred. Thus, by arranging the terminals for electrical connection with the core wire and the braided wire symmetrically with respect to the coaxial cable, the length in the longitudinal direction of the coaxial cable connection terminal can be shortened, and the product can be downsized. Can be realized. Furthermore, even when the board fixing portions 84a and 84b are provided, the wiring can be easily handled by arranging the terminals for electrical connection at the tip of the connection terminals.

また、第１接続端子６２と第２接続端子８３とを同軸ケーブルの長手方向の延長線に対して略対称に配置することによって端子間距離が接近するが、本実施例では内導体と外導体との間に絶縁体からなるホルダを設けているので、内導体と外導体とが接触しないようにすることができる。   Further, by arranging the first connection terminal 62 and the second connection terminal 83 substantially symmetrically with respect to the extension line in the longitudinal direction of the coaxial cable, the distance between the terminals approaches, but in this embodiment, the inner conductor and the outer conductor Since the holder made of an insulator is provided between the inner conductor and the outer conductor, the inner conductor and the outer conductor can be prevented from contacting each other.

なお、図１６（ｂ）に示すように、編組線接続部８１及び保護被膜保持部８２を基板と重ならないように配置することが好ましい。このような構成とすることによって、基板上の同軸ケーブル接続部が占める面積を小さくすることができ、接続部を小型化することができる。   In addition, as shown in FIG.16 (b), it is preferable to arrange | position the braided wire connection part 81 and the protective film holding | maintenance part 82 so that it may not overlap with a board | substrate. By setting it as such a structure, the area which the coaxial cable connection part on a board | substrate occupies can be made small, and a connection part can be reduced in size.

また、本実施例においては、同軸ケーブルに内導体、ホルダ、外導体を順に装着する方法を示したが、内導体を同軸ケーブルに装着する前に、内導体とホルダとを組込んでおいてもよいし、ホルダを内導体に装着する前にホルダと外導体とを組み込んでおいてもよい。さらに、本実施例においては内導体、外導体、ホルダを別体として組み込む例を示したが、樹脂の射出成型等によってホルダを内導体または外導体と一体化するようにしてもよい。   In the present embodiment, the method of attaching the inner conductor, the holder, and the outer conductor to the coaxial cable in order is shown. However, before the inner conductor is attached to the coaxial cable, the inner conductor and the holder are assembled. Alternatively, the holder and the outer conductor may be assembled before the holder is attached to the inner conductor. Further, in the present embodiment, an example in which the inner conductor, the outer conductor, and the holder are incorporated as separate bodies has been described. However, the holder may be integrated with the inner conductor or the outer conductor by resin injection molding or the like.

次に、本発明の第２の実施例に係る同軸ケーブル接続端子について説明する。実施例２の同軸ケーブル接続端子は、複数の同軸ケーブル接続端子を連結することが可能な構成となっている点を特徴としている。図１７に２つの同軸ケーブル接続端子を連結する場合の連結方法を示す。図１７（ａ）に示すように、第１の同軸ケーブル接続端子１１ａのホルダ７０１は、第２の同軸ケーブル接続端子１１ｂのホルダ７０２と連結するための凸部７１１と、他の同軸ケーブル接続端子と連結するための凹部７２１とを備えている。同様に、第２の同軸ケーブル接続端子１１ｂのホルダ７０２は、第１の同軸ケーブル接続端子１１ａのホルダ７０１と連結するための凹部７２２と、他の同軸ケーブル接続端子と連結するための凸部７１２とを備えている。ホルダ以外の構成は実施例１と同様であるので詳細な説明は省略する。   Next, the coaxial cable connection terminal according to the second embodiment of the present invention will be described. The coaxial cable connection terminal according to the second embodiment is characterized in that a plurality of coaxial cable connection terminals can be connected. FIG. 17 shows a connection method in the case of connecting two coaxial cable connection terminals. As shown in FIG. 17A, the holder 701 of the first coaxial cable connection terminal 11a includes a convex portion 711 for connecting to the holder 702 of the second coaxial cable connection terminal 11b, and another coaxial cable connection terminal. And a concave portion 721 for connection with the. Similarly, the holder 702 of the second coaxial cable connection terminal 11b includes a concave portion 722 for coupling with the holder 701 of the first coaxial cable connection terminal 11a, and a convex portion 712 for coupling with another coaxial cable connection terminal. And. Since the configuration other than the holder is the same as that of the first embodiment, detailed description thereof is omitted.

凸部７１１を凹部７２２に連結した状態を図１７（ｂ）に示す。ホルダの形状をこのように連結可能な構造とすることによって、複数の同軸ケーブル接続端子を基板への接続前に予め一体化しておくことができるので、基板へのセット作業を１回で済ませることができ、複数の接続端子を個々にセットする場合に比べて作業効率を改善することができる。また、本実施例においては、別体のホルダを連結するようにしているが、用途によっては、１つの大きなホルダに複数の同軸ケーブルをセットするようにしてもよい。   FIG. 17B shows a state where the convex portion 711 is connected to the concave portion 722. By making the shape of the holder connectable in this way, a plurality of coaxial cable connection terminals can be integrated in advance before connecting to the board, so that the setting work on the board can be done only once. Thus, the working efficiency can be improved as compared with the case where a plurality of connection terminals are individually set. In the present embodiment, separate holders are connected, but depending on the application, a plurality of coaxial cables may be set in one large holder.

次に、本発明の第３の実施例について説明する。第３の実施例は、芯線に内導体を設けずに、編組線に外導体を接続する点を特徴としている。図１８に、実施例３に係る同軸ケーブル接続端子の斜視図を示す。同軸ケーブル接続端子９は、基板接続用端子９３と、基板固定部９４ａ、９４ｂとを備えている。基板接続用端子９３は下方に垂下した構造を有しているが、同軸ケーブルの内部絶縁体と接する部分にはショート防止壁９００を備えている。さらに同軸ケーブル接続端子９は編組線接続部９１と保護被膜保持部９２とを備えている。編組線接続部９１は同軸ケーブルの編組線と電気的に接続され、保護被膜保持部９２は同軸ケーブルの保護被膜を保持する。   Next, a third embodiment of the present invention will be described. The third embodiment is characterized in that the outer conductor is connected to the braided wire without providing the inner conductor on the core wire. FIG. 18 is a perspective view of the coaxial cable connection terminal according to the third embodiment. The coaxial cable connection terminal 9 includes a substrate connection terminal 93 and substrate fixing portions 94a and 94b. The substrate connection terminal 93 has a structure that hangs downward, but is provided with a short prevention wall 900 at a portion in contact with the internal insulator of the coaxial cable. Further, the coaxial cable connection terminal 9 includes a braided wire connection portion 91 and a protective film holding portion 92. The braided wire connecting portion 91 is electrically connected to the braided wire of the coaxial cable, and the protective coating holding unit 92 holds the protective coating of the coaxial cable.

次に、同軸ケーブル接続端子９の同軸ケーブルへの接続方法について説明する。図１９は、同軸ケーブル接続端子９を上方から俯瞰した平面図である。同図（ａ）は同軸ケーブルを接続する前の状態を示し、同図（ｂ）は同軸ケーブルを接続した後の構造を示す。本実施例においては芯線には内導体を接続していないので芯線を直接基板等に接続する。また、接続部の小型化を行うために、編組線と電気的に接続された基板接続用端子９３の位置を芯線１の位置に接近させている。このように芯線１と基板接続用端子９３とを接近させた場合、両者が接触すると、短絡が生じる。そこで、本実施例においては同図（ｂ）に示すように、基板接続用端子９３にショート防止壁９００を設けている。ショート防止壁９００は同軸ケーブルの内部絶縁体２と当接し、基板接続用端子９３が芯線１と接触するのを防止している。このような構成とすることによって、同軸ケーブル接続端子９を小型化しても、芯線１と編組線との短絡を防止することができ、製品の小型化を実現することができる。   Next, a method for connecting the coaxial cable connection terminal 9 to the coaxial cable will be described. FIG. 19 is a plan view of the coaxial cable connection terminal 9 as seen from above. FIG. 2A shows a state before the coaxial cable is connected, and FIG. 2B shows a structure after the coaxial cable is connected. In this embodiment, since the inner conductor is not connected to the core wire, the core wire is directly connected to the substrate or the like. Further, in order to reduce the size of the connection portion, the position of the board connection terminal 93 electrically connected to the braided wire is brought close to the position of the core wire 1. When the core wire 1 and the board connection terminal 93 are brought close to each other in this way, a short circuit occurs when they come into contact with each other. Therefore, in this embodiment, as shown in FIG. 5B, a short-circuit prevention wall 900 is provided on the board connection terminal 93. The short prevention wall 900 is in contact with the inner insulator 2 of the coaxial cable to prevent the board connection terminal 93 from coming into contact with the core wire 1. With such a configuration, even if the coaxial cable connection terminal 9 is downsized, a short circuit between the core wire 1 and the braided wire can be prevented, and downsizing of the product can be realized.

以上、本発明の同軸ケーブル接続端子について、車両のフロントガラスに設けたアンテナエレメントと接続するアンテナアンプに用いる場合を例にとって説明したが、アンテナアンプ以外の基板に接続する場合にも本発明を適用することができる。   As described above, the coaxial cable connection terminal of the present invention has been described by way of example using the antenna amplifier connected to the antenna element provided on the windshield of the vehicle. can do.
