Description

本発明は、接続装置に関する。   The present invention relates to a connection device.

従来、複数の金属素線からなる電線の心線や編組線等の導電線の先端部に雌型端子等の端子が取り付けられ、この端子を相手方端子（例えば雄型端子）と接触させて両者を接続することで、導電線と相手方端子との間を導通させる接続装置が知られている。   Conventionally, a terminal such as a female terminal is attached to the tip of a conductive wire such as a core wire or a braided wire made of a plurality of metal wires, and this terminal is brought into contact with a mating terminal (for example, a male terminal). There is known a connection device that conducts between a conductive wire and a counterpart terminal by connecting.

このような接続装置の一例として、例えば特許文献１に記載のシールド電線用コネクタが知られている。このシールド電線用コネクタでは、編組線の先端部が加工されて雌型端子に取り付けられており、この雌型端子が相手方端子である雄型端子と接続されることで、編組線と雌型端子との間が導通されるようになっている。   As an example of such a connection device, for example, a shielded wire connector described in Patent Document 1 is known. In this shielded wire connector, the end of the braided wire is processed and attached to the female terminal, and this female terminal is connected to the male terminal that is the counterpart terminal, so that the braided wire and the female terminal are connected. Between the two is made conductive.

特開平１１−１２１０９５号公報Japanese Patent Laid-Open No. 11-121095

上記特許文献１の接続装置において雌型端子と雄型端子とが接続されると、編組線と雌型端子との間には、両端子の接点における接触抵抗と、当該接点と編組線の取付部との間の雌型端子の導体抵抗と、雌型端子と編組線との接点における接触抵抗と、がそれぞれ生じ、編組線と雄型端子との間を通電させることでこれらの各抵抗が発熱する。このため、編組線と雄型端子との間に大電流を通電させると発熱量が多くなってしまい、発熱量を抑制することが要求される機器においては問題であった。   When the female terminal and the male terminal are connected in the connection device of Patent Document 1, the contact resistance at the contact of both terminals and the attachment of the contact and the braided wire are between the braided wire and the female terminal. Conductor resistance between the female terminal and the contact resistance at the contact point between the female terminal and the braided wire, respectively. Fever. For this reason, when a large current is passed between the braided wire and the male terminal, the amount of heat generation increases, which is a problem in devices that are required to suppress the amount of heat generation.

本発明は、上記の課題に鑑みて創作されたものであって、導電線と相手側端子との接続に伴う発熱量を抑制することを目的とする。   The present invention has been created in view of the above-described problems, and an object thereof is to suppress the amount of heat generated due to the connection between a conductive wire and a counterpart terminal.

本発明の接続装置は、複数の金属素線からなり、その一部に接触部が設けられた導電線と、前記接触部と接触して前記導電線と接続される相手側端子と、前記接触部と前記相手側端子との接点に接圧を付与する接圧付与部と、を備え、前記導電線と前記相手側端子との接続時に、前記接圧付与部が前記接点に接圧を付与しながら前記接触部と前記相手側端子とが接触することで、前記導電線と前記相手側端子との間が導通されることを特徴とする。   The connection device of the present invention is composed of a plurality of metal strands, a conductive wire provided with a contact portion at a part thereof, a mating terminal that contacts the contact portion and is connected to the conductive wire, and the contact A contact pressure applying portion that applies contact pressure to a contact between the contact portion and the counterpart terminal, and the contact pressure applying portion applies contact pressure to the contact when the conductive wire and the counterpart terminal are connected. However, when the contact portion and the mating terminal come into contact, the conductive wire and the mating terminal are electrically connected.

この接続装置によると、導電線の接触部が端子を介することなく相手側端子と直接接触し、その接点に接圧が付与されることで両者の間が導通される。このような接続態様とすることで、端子と導電線との間に生じる接触抵抗をなくすことができる。さらに、導体抵抗が導電線に生じることとなり、端子の板厚に依存しないものとなるので、導体抵抗を低減することができる。このため、導電線が取り付けられた端子と相手側端子とが接続されることで導電線と相手方端子との間が導通される従来の接続装置と比べて、導電線と相手側端子との間に生じる抵抗を大きく低減させることができる。その結果、導電線と相手側端子との接続に伴う発熱量を抑制することができる。   According to this connection device, the contact portion of the conductive wire comes into direct contact with the mating terminal without passing through the terminal, and the contact pressure is applied to the contact point, thereby conducting electrical connection therebetween. By setting it as such a connection aspect, the contact resistance which arises between a terminal and a conductive wire can be eliminated. Furthermore, since conductor resistance is generated in the conductive wire and does not depend on the terminal thickness, the conductor resistance can be reduced. For this reason, compared with the conventional connection apparatus with which conduction | electrical_connection between a conductive wire and the other party terminal is conduct | electrically connected by connecting the terminal to which the conductive wire was attached, and the other party terminal, between a conductive wire and the other party terminal Can be greatly reduced. As a result, the amount of heat generated due to the connection between the conductive wire and the counterpart terminal can be suppressed.

上記の接続装置において、前記接触部は突出状とされ、前記相手側端子は雄型端子であり、内部に弾性片が設けられた雌型端子を備えるとともに、該弾性片が前記接圧付与部とされ、前記導電線と前記雄型端子との接続時に、前記雄型端子が前記接触部と前記弾性片との間に挟持されることで、前記導電線と前記雄型端子との間が導通されてもよい。   In the above connection device, the contact portion is formed in a protruding shape, the mating terminal is a male terminal, and includes a female terminal provided with an elastic piece therein, and the elastic piece is the contact pressure applying portion. When the conductive wire and the male terminal are connected, the male terminal is sandwiched between the contact portion and the elastic piece, so that the conductive wire and the male terminal are separated. It may be conducted.

この構成によると、雄型端子が突出状とされた導電線の接触部と弾性片との間に挟持されることで、弾性片の弾性力によって接触部と雄型端子との接点に接圧が付与される。このため、導電線の接触部を雄型端子に直接接触させて両者の間を導通させることができる。その結果、導電線と雄型端子との間の抵抗を低減させることができ、導電線と雄型端子との接続に伴う発熱量を抑制することができる。   According to this configuration, the male terminal is sandwiched between the contact portion of the protruding conductive wire and the elastic piece, so that the contact force between the contact portion and the male terminal is contacted by the elastic force of the elastic piece. Is granted. For this reason, the contact portion of the conductive wire can be brought into direct contact with the male terminal to conduct between them. As a result, the resistance between the conductive wire and the male terminal can be reduced, and the amount of heat generated due to the connection between the conductive wire and the male terminal can be suppressed.

上記の接続装置において、前記接触部は突出状とされ、前記相手側端子は雌型端子であり、前記接触部の内部に弾性部材が配されるとともに、該弾性部材が前記接圧付与部とされ、前記導電線と前記雌型端子との接続時に、前記接触部が前記雌型端子の内壁に挟持されることで、前記導電線と前記雌型端子との間が導通されてもよい。   In the above connection device, the contact portion has a protruding shape, the counterpart terminal is a female terminal, an elastic member is disposed inside the contact portion, and the elastic member is connected to the contact pressure applying portion. In addition, when the conductive wire and the female terminal are connected, the contact portion may be sandwiched between inner walls of the female terminal so that the conductive wire and the female terminal are electrically connected.

この構成によると、突出状とされた接触部が弾性部材側に押圧された場合、弾性部材の弾性復帰力によって接触部に弾性部材側とは反対側、即ち外側向きの力が付与される。このため、突出状とされた導電線の接触部が雌型端子の内壁に挟持されることで、上記弾性復帰力によって接触部に外側向きの力が付与されて当該接触部と雌型端子との接点に接圧が付与され、導電線の接触部を雌型端子に直接接触させた状態で両者の間を導通させることができる。その結果、導電線と雌型端子との間の抵抗を低減させることができ、導電線と雌型端子との接続に伴う発熱量を抑制することができる。   According to this configuration, when the protruding contact portion is pressed to the elastic member side, a force opposite to the elastic member side, that is, an outward force is applied to the contact portion by the elastic restoring force of the elastic member. For this reason, the contact portion of the protruding conductive wire is sandwiched between the inner walls of the female terminal, so that an outward force is applied to the contact portion by the elastic return force, and the contact portion and the female terminal A contact pressure is applied to each contact point, and the conductive wire contact portion can be brought into electrical contact with the female terminal in a state where the contact portion is in direct contact with the female terminal. As a result, the resistance between the conductive wire and the female terminal can be reduced, and the amount of heat generated due to the connection between the conductive wire and the female terminal can be suppressed.

本発明によれば、導電線と相手側端子との接続に伴う発熱量を抑制することができる。   According to this invention, the emitted-heat amount accompanying the connection of a conductive wire and the other party terminal can be suppressed.

＜実施形態１＞
図１及び図２を参照して実施形態１を説明する。本実施形態の接続装置１は、例えばハイブリッド自動車や電気自動車におけるインバータとモータとの間の接続に用いられるものである。本実施形態の接続装置１は、図１に示すように、電線の心線（導電線の一例）１２が収容された雌型端子１０と、雄型端子（相手側端子の一例）２０とから構成され、両端子１０，２０を接続することで心線３０と雄型端子２０との間を導通させる装置である。 <Embodiment 1>
The first embodiment will be described with reference to FIGS. 1 and 2. The connection device 1 of the present embodiment is used for connection between an inverter and a motor in, for example, a hybrid vehicle or an electric vehicle. As shown in FIG. 1, the connection device 1 of the present embodiment includes a female terminal 10 in which a core wire (an example of a conductive wire) 12 is accommodated and a male terminal (an example of a mating terminal) 20. The device is configured to connect between the core wire 30 and the male terminal 20 by connecting both terminals 10 and 20.

雌型端子１０は、金属製の略角筒状をなし、その一方の開口が、雄型端子２０が挿入される接続開口１０Ａとされる。接続開口１０Ａの一部には、接続開口１０Ａから雌型端子１０の内部側に向かって屈曲して延びる弾性片（接圧付与部の一例）１２が設けられている。   The female terminal 10 has a substantially rectangular shape made of metal, and one opening thereof is a connection opening 10A into which the male terminal 20 is inserted. An elastic piece (an example of a contact pressure applying portion) 12 that is bent and extends from the connection opening 10A toward the inner side of the female terminal 10 is provided in a part of the connection opening 10A.

雌型端子１０に設けられた弾性片１２は、図１に示す断面視において雌型端子１０の内部側に向かって凸状となった略山形状をなしている。これにより弾性片１２は、雌型端子１０の筒軸方向と直交する方向に弾性変形可能とされている。   The elastic piece 12 provided in the female terminal 10 has a substantially mountain shape that is convex toward the inner side of the female terminal 10 in a cross-sectional view shown in FIG. Thus, the elastic piece 12 can be elastically deformed in a direction orthogonal to the cylinder axis direction of the female terminal 10.

一方、図１に示すように、雌型端子１０の内部には、上記弾性片１２と対向する形で、電線の先端部において絶縁被覆から取り出された心線３０が収容されている。雌型端子１０に収容された心線３０は、複数の金属素線からなっており、抵抗溶接によって雌型端子１０の内壁に接合されている。   On the other hand, as shown in FIG. 1, a core wire 30 taken out from the insulation coating at the tip end portion of the electric wire is accommodated inside the female terminal 10 so as to face the elastic piece 12. The core wire 30 accommodated in the female terminal 10 is composed of a plurality of metal wires, and is joined to the inner wall of the female terminal 10 by resistance welding.

雌型端子１０に収容された心線３０の一部には、弾性片１２側に向かって略山形の突出状とされた接触部３２が設けられている。このような接触部３２は、抵抗溶接によって心線３０を雌型端子１０に接合する際に、心線３０の一部に高低差を設けて抵抗溶接によって心線３０を固めることで加工形成することができる。   A part of the core wire 30 accommodated in the female terminal 10 is provided with a contact portion 32 having a substantially chevron protruding toward the elastic piece 12 side. Such a contact portion 32 is formed by forming a height difference in a part of the core wire 30 and solidifying the core wire 30 by resistance welding when joining the core wire 30 to the female terminal 10 by resistance welding. be able to.

略山形の突出状とされた接触部３２は、その頂点部が略山形をなす弾性片１２の頂点部とほぼ対向するような位置に設けられている。雌型端子１０の接続開口１０Ａ側から挿入される雄型端子２０は、この接触部３２と弾性片１２との間に挟み込まれるような形で、雄型端子２０の内部に挿入される。   The contact portion 32 having a substantially chevron-shaped protruding shape is provided at a position where the apex portion thereof is substantially opposite to the apex portion of the elastic piece 12 having a substantially chevron shape. The male terminal 20 inserted from the connection opening 10A side of the female terminal 10 is inserted into the male terminal 20 so as to be sandwiched between the contact portion 32 and the elastic piece 12.

雄型端子２０は、軸状をなす導電部材であり、雄型端子２０の内部に挿入される先端部の外径が、雌型端子１０の内部に配された接触部３２と弾性片１２との間の距離よりもわずかに大きなものとなっている。   The male terminal 20 is a conductive member having an axial shape, and the outer diameter of the distal end portion inserted into the male terminal 20 has a contact portion 32 and an elastic piece 12 disposed inside the female terminal 10. It is slightly larger than the distance between.

続いて本実施形態の接続装置１における雌型端子１０と雄型端子２０の接続態様について説明する。上述したように、接続装置１において雌型端子１０と雄型端子２０とを接続する場合、雄型端子２０の先端部を、雌型端子１０の接続開口１０Ａから接触部３２と弾性片１２の間に挿入する（図１の矢印参照）。   Then, the connection aspect of the female terminal 10 and the male terminal 20 in the connection apparatus 1 of this embodiment is demonstrated. As described above, when the female terminal 10 and the male terminal 20 are connected in the connection device 1, the tip of the male terminal 20 is connected to the contact portion 32 and the elastic piece 12 from the connection opening 10 </ b> A of the female terminal 10. Insert between them (see arrow in FIG. 1).

すると、雄型端子２０の先端部によって弾性片１２が押圧されて雌型端子１０の外側方向に向かって弾性変形し、雄型端子２０の先端部を雌型端子１０の内部にさらに挿入することにより、図２に示すように、雄型端子２０の先端部が突出状とされた接触部３２と弾性片１２との間に挟持された状態となる。   Then, the elastic piece 12 is pressed by the distal end portion of the male terminal 20 and elastically deforms toward the outer side of the female terminal 10, and the distal end portion of the male terminal 20 is further inserted into the female terminal 10. As a result, as shown in FIG. 2, the tip of the male terminal 20 is sandwiched between the protruding contact portion 32 and the elastic piece 12.

この状態では、弾性片１２の弾性復帰力によって、接触部３２と雄型端子２０との接点Ｃ１及び弾性片１２と雄型端子２０との接点Ｃ２にそれぞれ接圧が付与される。これにより、雄型端子２０が雌型端子１０から抜け止めされるとともに、接触部３２と雄型端子２０との間で良好な接触が図られ、心線３０と雄型端子２０との間を導通させることができる。   In this state, contact pressure is applied to the contact C1 between the contact portion 32 and the male terminal 20 and the contact C2 between the elastic piece 12 and the male terminal 20 by the elastic restoring force of the elastic piece 12. Thereby, the male terminal 20 is prevented from being detached from the female terminal 10, and good contact is achieved between the contact portion 32 and the male terminal 20, and between the core wire 30 and the male terminal 20. It can be made conductive.

以上説明したように本実施形態の接続装置１では、雄型端子２０が突出状とされた心線３０の接触部３２と弾性片１２との間に挟持されることで、心線３０の接触部３２が雌型端子１０を介することなく雄型端子２０と直接接触し、弾性片１２によってその接点Ｃ１に接圧が付与されることで心線３０と雄型端子２０との間が導通される。本実施形態では、心線３０と雄型端子２０との間がこのような接続態様で接続されることで、雌型端子１０と心線３０との間に生じる接触抵抗をなくすことができる。   As described above, in the connection device 1 according to this embodiment, the male terminal 20 is sandwiched between the contact portion 32 of the protruding core wire 30 and the elastic piece 12 so that the contact of the core wire 30 is achieved. The portion 32 directly contacts the male terminal 20 without going through the female terminal 10, and contact force is applied to the contact C <b> 1 by the elastic piece 12, thereby conducting between the core wire 30 and the male terminal 20. The In the present embodiment, the contact resistance generated between the female terminal 10 and the core wire 30 can be eliminated by connecting the core wire 30 and the male terminal 20 in such a connection mode.

また、雌型端子１０と雄型端子２０とが接続された状態では、心線３０と雄型端子２０との間に、接触部３２と雄型端子２０の接点における接触抵抗と、心線３０の導体抵抗と、がそれぞれ生じる。ここで、導体抵抗はその導体の厚みに反比例し、雌型端子１０の板厚は心線３０の外径よりも小さいが、本実施形態では心線３０に導体抵抗が生じるため、導体抵抗が雌型端子１０の板厚に依存しないものとなり、雌型端子１０に導体抵抗が生じる従来のものと比べて導体抵抗を低減することができる。   When the female terminal 10 and the male terminal 20 are connected, the contact resistance between the contact portion 32 and the male terminal 20 and the core wire 30 are between the core wire 30 and the male terminal 20. Are respectively generated. Here, the conductor resistance is inversely proportional to the thickness of the conductor, and the plate thickness of the female terminal 10 is smaller than the outer diameter of the core wire 30. However, in this embodiment, the conductor resistance is generated in the core wire 30. It becomes a thing which does not depend on the plate | board thickness of the female terminal 10, and can reduce a conductor resistance compared with the conventional thing which a conductor resistance produces in the female terminal 10. FIG.

このように本実施形態の接続装置１では、心線が取り付けられた雌型端子と雄型端子とが接続されることで心線と雄型端子との間が導通される従来の接続装置と比べて、心線３０と雄型端子２０との間に生じる抵抗を大きく低減させることができる。その結果、心線３０と雄型端子２０との接続に伴う発熱量を抑制することができる。   As described above, in the connection device 1 according to the present embodiment, the connection between the female terminal to which the core wire is attached and the male terminal so that the core wire and the male terminal are electrically connected to each other. In comparison, the resistance generated between the core wire 30 and the male terminal 20 can be greatly reduced. As a result, the amount of heat generated due to the connection between the core wire 30 and the male terminal 20 can be suppressed.

ここで自動車におけるインバータとモータとの間の接続においては、モータの内部が熱くなり易いため、インバータとモータとの間の接続に本実施形態の接続装置１を用いることで、インバータとモータとの間の接続に伴う発熱量を大きく抑制することができる。   Here, in the connection between the inverter and the motor in the automobile, the inside of the motor is likely to become hot. Therefore, by using the connection device 1 of the present embodiment for the connection between the inverter and the motor, the connection between the inverter and the motor is achieved. The amount of heat generated due to the connection between the two can be greatly suppressed.

特にハイブリッド自動車や電気自動車におけるインバータとモータとの間の接続においては、両者の間に大電流が流れるため発熱量を抑制する必要があり、インバータとモータとの間の接続において本実施形態の接続装置１を用いることは好適である。   Particularly in the connection between the inverter and the motor in a hybrid vehicle or an electric vehicle, it is necessary to suppress the amount of heat generated because a large current flows between the two, and the connection of this embodiment in the connection between the inverter and the motor It is preferable to use the device 1.

また上述したように本実施形態の接続装置１では、雌型端子１０と雄型端子２０とが接続された状態で生じる導体抵抗が雌型端子１０の板厚に依存しないものとなる。このため、心線３０と雄型端子２０との接続に伴う発熱量を抑制しながら雌型端子１０の板厚を薄くすることができ、雌型端子１０の小型化を図ることもできる。   Further, as described above, in the connection device 1 according to the present embodiment, the conductor resistance generated in a state where the female terminal 10 and the male terminal 20 are connected does not depend on the plate thickness of the female terminal 10. For this reason, the plate | board thickness of the female terminal 10 can be made thin, suppressing the emitted-heat amount accompanying the connection with the core wire 30 and the male terminal 20, and the size reduction of the female terminal 10 can also be achieved.

図３及び図４を参照して実施形態２を説明する。本実施形態の接続装置１０１は、実施形態１のものと同様に、例えばハイブリッド自動車や電気自動車におけるインバータとモータとの間の接続に用いられるものである。本実施形態の接続装置１０１は、図３に示すように、電線の心線（導電線の一例）１３０と、雌型端子（相手側端子の一例）１１０とから構成され、両者１３０，１１０を接続することで両者１３０，１１０の間を導通させる装置である。 <Embodiment 2>
The second embodiment will be described with reference to FIGS. 3 and 4. Similar to the first embodiment, the connection device 101 according to the present embodiment is used for connection between an inverter and a motor in a hybrid vehicle or an electric vehicle, for example. As shown in FIG. 3, the connection device 101 according to the present embodiment includes a core wire (an example of a conductive wire) 130 and a female terminal (an example of a mating terminal) 110. It is a device that conducts between the both 130 and 110 by connecting.

心線１３０は、実施形態１のものと同様に、電線の先端部において絶縁被覆から取り出されたものであり、図３に示すように、その先端部の両側に外側に向かって略山形の突出状とされた接触部１３２，１３２がそれぞれ設けられている。   The core 130 is taken out of the insulation coating at the tip of the electric wire, as in the first embodiment. As shown in FIG. 3, as shown in FIG. Contact portions 132 and 132 each having a shape are provided.

両接触部１３２，１３２の内部には、弾性部材（接圧付与部の一例）１４０が埋め込まれる形で配されている。このような弾性部材１４０としては、例えば材料がステンレス鋼（ＳＵＳ）やリン青銅からなるバネ部材を用いることができる。   An elastic member (an example of a contact pressure applying unit) 140 is disposed in the contact portions 132 and 132 in an embedded manner. As such an elastic member 140, for example, a spring member made of stainless steel (SUS) or phosphor bronze can be used.

両接触部１３２，１３２は、実施形態１のものと同様に、心線１３０の一部に高低差を設けて抵抗溶接によって心線１３０を固めることで加工形成することができる。また、弾性部材１４０についても、上記抵抗溶接を行う際に、両接触部１３２，１３２の内部に埋め込むことができる。   Both the contact portions 132 and 132 can be formed by forming a height difference in a part of the core 130 and hardening the core 130 by resistance welding in the same manner as in the first embodiment. Further, the elastic member 140 can also be embedded in the contact portions 132 and 132 when the resistance welding is performed.

両接触部１３２，１３２の内部に配された弾性部材１４０は、心線１３０の線軸方向と直交する方向に弾性変形可能な姿勢で配されている。このため、両接触部１３２，１３２は、弾性部材１４０が弾性変形することにより、心線１３０の線軸方向と直交する方向にわずかに移動するようになっている。   The elastic members 140 disposed inside the contact portions 132 and 132 are disposed in a posture capable of being elastically deformed in a direction orthogonal to the linear axis direction of the core wire 130. For this reason, both the contact parts 132 and 132 are moved slightly in the direction orthogonal to the linear axis direction of the core wire 130 when the elastic member 140 is elastically deformed.

雌型端子１１０は、金属製の略角筒状をなし、その一方の開口が、心線１３０が挿入される接続開口１１０Ａとされる。雌型端子１１０の内径は、心線１３０における両接触部１３２，１３２が設けられた部位の幅よりもわずかに小さいものとなっている。   The female terminal 110 has a substantially rectangular tube shape made of metal, and one opening thereof serves as a connection opening 110A into which the core wire 130 is inserted. The inner diameter of the female terminal 110 is slightly smaller than the width of the portion of the core wire 130 where both contact portions 132 and 132 are provided.

続いて本実施形態の接続装置１０１における心線１３０と雌型端子１１０の接続態様について説明する。接続装置１０１において心線１３０と雌型端子１１０とを接続する場合、心線１３０の先端部を、雌型端子１１０の接続開口１１０Ａから挿入する（図３の矢印参照）。   Next, a connection mode between the core wire 130 and the female terminal 110 in the connection device 101 of the present embodiment will be described. When connecting the core wire 130 and the female terminal 110 in the connection apparatus 101, the front-end | tip part of the core wire 130 is inserted from the connection opening 110A of the female terminal 110 (refer the arrow of FIG. 3).

すると、突出状とされた心線１３０の両接触部１３２，１３２が雌型端子１１０の内壁によって弾性部材１４０側に押圧され、弾性部材１４０が内側に向かって弾性変形する。そして、心線１３０の先端部を雌型端子１０の内部にさらに挿入することにより、図４に示すように、心線１３０の両接触部１３２，１３２が雌型端子１１０の内壁に挟持された状態となる。   Then, both contact portions 132, 132 of the protruding core wire 130 are pressed toward the elastic member 140 by the inner wall of the female terminal 110, and the elastic member 140 is elastically deformed inward. Then, by further inserting the distal end portion of the core wire 130 into the female terminal 10, both contact portions 132, 132 of the core wire 130 are held between the inner walls of the female terminal 110 as shown in FIG. It becomes a state.

この状態では、弾性部材１４０の弾性復帰力によって、両接触部１３２，１３２に弾性部材１４０側とは反対側、即ち雌型端子１１０の内壁側向きの力が付与され、両接触部１３２，１３２と雌型端子１１０の内壁との接点Ｃ３，Ｃ４にそれぞれ接圧が付与される。これにより、心線１３０が雌型端子１１０から抜け止めされるとともに、両接触部１３２，１３２と雌型端子１１０との間で良好な接触が図られ、心線１３０と雌型端子１１０との間を導通させることができる。   In this state, due to the elastic restoring force of the elastic member 140, a force opposite to the elastic member 140 side, i.e., the inner wall side of the female terminal 110, is applied to both contact portions 132, 132. And contact pressures are applied to the contacts C3 and C4 with the inner wall of the female terminal 110, respectively. Thus, the core wire 130 is prevented from being detached from the female terminal 110, and good contact is achieved between the contact portions 132, 132 and the female terminal 110. It is possible to conduct between them.

以上説明したように本実施形態の接続装置１０１では、突出状とされた心線１３０の両接触部１３２，１３２が雌型端子１１０の内壁に挟持されることで、心線１３０の両接触部１３２，１３２が他の端子部材を介することなく雄型端子１２０と直接接触し、弾性部材１４０によってそれらの接点Ｃ３，Ｃ４も接圧が付与されることで心線１３０と雌型端子１１０との間が導通される。本実施形態では、心線１３０と雌型端子１１０との間がこのような接続態様で接続されることで、他の端子部材と心線１３０との間に生じる接触抵抗をなくすことができる。   As described above, in the connection device 101 according to the present embodiment, the two contact portions 132 and 132 of the protruding core wire 130 are held between the inner walls of the female terminal 110, so 132 and 132 are in direct contact with the male terminal 120 without passing through other terminal members, and contact points are also applied to the contact points C3 and C4 by the elastic member 140, whereby the core wire 130 and the female terminal 110 are connected. The connection is conducted. In this embodiment, since the core wire 130 and the female terminal 110 are connected in this manner, contact resistance generated between the other terminal members and the core wire 130 can be eliminated.

このように本実施形態の接続装置１０１では、心線が取り付けられた他の端子部材と雌型端子とが接続されることで心線と雌型端子との間が導通される従来の接続装置と比べて、心線１３０と雌型端子１１０との間に生じる抵抗を大きく低減させることができる。その結果、心線１３０と雌型端子１１０との接続に伴う発熱量を抑制することができる。   As described above, in the connection device 101 according to the present embodiment, the connection between the core wire and the female terminal is established by connecting the other terminal member to which the core wire is attached and the female terminal. As compared with the above, the resistance generated between the core 130 and the female terminal 110 can be greatly reduced. As a result, the amount of heat generated due to the connection between the core 130 and the female terminal 110 can be suppressed.
