高周波信号を伝送する場合、高周波対応のシールド電線、およびそのシールド電線に電気的に接続されるコネクタが用いられる。そのようなシールド電線およびコネクタは、自動車等の車両で車載機器間の高周波信号の伝送にも用いられており、車載用のコネクタには小型化の要求が強まっている。 When transmitting a high-frequency signal, a shielded electric wire for high frequency and a connector electrically connected to the shielded electric wire are used. Such shielded wires and connectors are also used for transmission of high-frequency signals between in-vehicle devices in vehicles such as automobiles, and there is an increasing demand for miniaturization of in-vehicle connectors.

上記シールド電線は、芯線の外側に内部被覆を介してシールド部材（編組等）を配し、シールド部材の外周を外部被覆（シース）で被覆した構造をなしている。一方、上記コネクタは、芯線に接続される芯線導通端子と、芯線導通端子を収容する筒状の絶縁部材と、絶縁部材を支持すると共に、シールド電線のシールド部材が接続される筒状のシールド部とを備えた構造をなしている。 The shielded electric wire has a structure in which a shield member (a braid or the like) is disposed on the outside of the core wire via an inner sheath, and the outer periphery of the shield member is covered with an outer sheath (sheath). On the other hand, the connector includes a core wire conducting terminal connected to the core wire, a cylindrical insulating member that accommodates the core wire conducting terminal, and a cylindrical shield portion that supports the insulating member and is connected to the shield member of the shielded electric wire.

Moreover, since it is necessary to connect the core wire Wa of the shielded electric wire W to the core wire conduction terminal 112, a crimping, pressure welding, or soldering process is required.

Further, one end portion of the female shielded electric wire W1 is inserted into the insulating member 12 from the rear side in the insertion direction of the insulating member 12 so that the core wire Wa is inserted into the central hole 12a of the insulating member 12 (FIG. 3D). ) Shows how the shielded electric wire W1 is inserted into the insulating member 12.), and the shielded electric wire W1 is connected to the terminal body 10. When one end of the female shielded electric wire W1 is inserted into the insulating member 12, the concave portion 1 of the shielded electric wire W1 is positioned behind the tapered portion 12b of the insulating member 12 in the insertion direction.

絶縁部材１２、２２にシールド電線Ｗ１、Ｗ２の一端部を挿入する際、シールド電線Ｗ１、Ｗ２の各シールド部材Ｗｃをシールド部１１、２１の一端部であるシールド部材接続部に電気接続する。この接続は、圧着やハンダ等の何の手段によってもよい。 When inserting one end portions of the shielded wires W1 and W2 into the insulating members 12 and 22, each shield member Wc of the shielded wires W1 and W2 is electrically connected to a shield member connecting portion which is one end portion of the shield portions 11 and 21. This connection may be made by any means such as crimping or soldering.

図１に示すように、端子本体１０のシールド部１１の外径と、端子本体２０のシールド部２１の内径と、が略一致するようにシールド部１１、２１を形成することにより、端子本体２０のシールド部２１が、空隙２３に端子本体１０のシールド部１１の一部を収容するように、該シールド部１１の一部を嵌合する。 As shown in FIG. 1, the terminal body 20 is formed by forming the shield parts 11, 21 so that the outer diameter of the shield part 11 of the terminal body 10 and the inner diameter of the shield part 21 of the terminal body 20 substantially coincide with each other. Part of the shield part 11 is fitted so that the shield part 21 accommodates part of the shield part 11 of the terminal body 10 in the gap 23.

端子本体２０のシールド部２１が端子本体１０のシールド部１１を嵌合する過程において、シールド電線Ｗ２の凸部２の先端部は、まず、絶縁部材１２のテーパ部１２ｂに臨む。端子本体１０の絶縁部材１２にテーパ部１２ｂが形成されていることにより、端子本体２０のシールド部２１に端子本体１０のシールド部１１を嵌合する際に、オス側のシールド電線Ｗ２の凸部２が端子本体１０の絶縁部材１２に接触することによって損傷してしまうことを防ぐことができる。シールド電線Ｗ２の凸部２の先端部が絶縁部材１２のテーパ部１２ｂの通過するころには、端子本体２０のシールド部２１の軸心と端子本体１０のシールド部１１の軸心とは一致しており、このため、シールド電線Ｗ１の軸心とシールド電線Ｗ２の軸心もまた一致している。この結果、端子本体２０のシールド部２１に端子本体１０のシールド部１１を嵌合することによって、シールド電線Ｗ１の凹部１にシールド電線Ｗ２の凸部２を嵌合することができる。これにより、シールド電線Ｗ１のシールド部材Ｗｃとシールド電線Ｗ２のシールド部材Ｗｃとがシールド部１１、２１を介して電気的に接続されるとともに、シールド電線Ｗ１の芯線Ｗａとシールド電線Ｗ２の芯線Ｗａとが電気的に接続される。 In the process in which the shield portion 21 of the terminal body 20 is engaged with the shield portion 11 of the terminal body 10, the tip end portion of the convex portion 2 of the shielded electric wire W 2 first faces the tapered portion 12 b of the insulating member 12. Since the tapered portion 12b is formed on the insulating member 12 of the terminal body 10, when the shield portion 11 of the terminal body 10 is fitted to the shield portion 21 of the terminal body 20, the convex portion of the male shielded electric wire W2 is formed. It can be prevented that 2 is damaged by contacting the insulating member 12 of the terminal body 10. When the tip of the convex portion 2 of the shielded electric wire W2 passes through the tapered portion 12b of the insulating member 12, the axis of the shield portion 21 of the terminal body 20 and the axis of the shield portion 11 of the terminal body 10 coincide. For this reason, the axis of the shielded electric wire W1 and the axis of the shielded electric wire W2 also coincide. As a result, by fitting the shield part 11 of the terminal main body 10 to the shield part 21 of the terminal main body 20, the convex part 2 of the shielded electric wire W2 can be fitted to the concave part 1 of the shielded electric wire W1. Accordingly, the shield member Wc of the shielded electric wire W1 and the shield member Wc of the shielded electric wire W2 are electrically connected via the shield portions 11 and 21, and the core wire Wa of the shielded electric wire W1 and the core wire Wa of the shielded electric wire W2 Are electrically connected.

以上、本発明に係る実施形態のシールド電線付きコネクタによれば、互いに接続すべきシールド電線Ｗ１、Ｗ２の芯線Ｗａの各先端面に凹部１と凸部２を設け、それら凹部１と凸部２を直接嵌合することで、芯線Ｗａ同士を接続するようにしているので、従来の芯線導通端子を不要にすることができる。従って、従来の芯線導通端子が占有していたスペースを、絶縁部材１１、２１のスペースとして利用することができ、シールド部１１、２１の外径サイズを小型にすることができ、ケーブル接続部分の小型化が可能になる。また、部品点数も少なくて済むので、コスト削減にも貢献できるし、圧着や圧接あるいはハンダ工程も不要になる。また、一方の絶縁部材１２の内部で凹部１と凸部２を嵌合するので、スムーズに嵌合することができる上、嵌合部分を絶縁部材１２で保護することができるので、信頼性も増す。 As mentioned above, according to the connector with a shielded wire according to the embodiment of the present invention, the concave portion 1 and the convex portion 2 are provided on the respective end surfaces of the core wires Wa of the shielded wires W1 and W2 to be connected to each other. Since the core wires Wa are connected to each other by directly fitting, the conventional core wire conduction terminals can be made unnecessary. Accordingly, the space occupied by the conventional core wire conduction terminal can be used as the space for the insulating members 11 and 21, the outer diameter size of the shield portions 11 and 21 can be reduced, and the cable connection portion can be reduced. Miniaturization is possible. In addition, since the number of parts can be reduced, it is possible to contribute to cost reduction, and there is no need for crimping, pressure welding or soldering. Further, since the concave portion 1 and the convex portion 2 are fitted inside one insulating member 12, the fitting portion can be smoothly fitted and the fitting portion can be protected by the insulating member 12, so that the reliability is also high. Increase.

尚、図１から図３を参照して説明した本発明に係る実施形態では、シールド電線Ｗ２の芯線Ｗａの凸部２がシールド部２１内部の空隙２３に突出する構造のシールド電線付きコネクタについて説明した。これとは反対に、図４の本発明に係る実施形態のシールド電線付きコネクタの構造図の他例に示すようなシールド電線付きコネクタを構成してもよい。すなわち、端子本体１０にオス側のシールド電線Ｗ２を挿通し、端子本体２０にメス側のシールド電線Ｗ１を挿通することによって、シールド電線Ｗ１の芯線Ｗａの凹部１がシールド部２１内部の空隙２３に突出する構造であってもよい。この構造であっても、図１に示すシールド電線Ｗ２の芯線Ｗａの凸部２がシールド部２１内部の空隙２３に突出する構造と、同様の効果が得られる。 In the embodiment according to the present invention described with reference to FIGS. 1 to 3, a connector with a shielded wire having a structure in which the convex portion 2 of the core wire Wa of the shielded wire W 2 projects into the gap 23 inside the shield portion 21 is described. did. On the contrary, a connector with a shielded wire as shown in another example of the structural diagram of the connector with a shielded wire according to the embodiment of the present invention in FIG. 4 may be configured. That is, by inserting the male shielded electric wire W2 into the terminal main body 10 and the female shielded electric wire W1 into the terminal main body 20, the concave portion 1 of the core wire Wa of the shielded electric wire W1 becomes a gap 23 inside the shield portion 21. A protruding structure may be used. Even with this structure, the same effect as the structure in which the convex portion 2 of the core wire Wa of the shielded electric wire W2 shown in FIG. 1 protrudes into the gap 23 inside the shield portion 21 can be obtained.
