Description

本発明は、圧接コネクタに関する。   The present invention relates to a pressure contact connector.

従来、電線に食い込ませる圧接刃を備えた圧接端子として、例えば下記特許文献1ないし4に記載のものが知られている。これらの圧接端子はいずれも、電線を保持する保持部を有し、この保持部によって保持された電線に対して圧接刃を食い込ませ、圧接刃が電線の被覆を突き破って芯線に接触することにより電線と圧接端子とが電気的に接続されるようになっている。   Conventionally, as a press contact terminal provided with a press contact blade that bites into an electric wire, for example, those described in Patent Documents 1 to 4 below are known. Each of these press contact terminals has a holding part for holding the electric wire, and the press contact blade bites into the electric wire held by the holding part, and the press contact blade breaks through the coating of the electric wire to contact the core wire. The electric wire and the press contact terminal are electrically connected.

しかしながら、上記の圧接コネクタでは、電線が保持部によって保持されているものの、保持部と非接触の部分がフリーとなっているため、圧接刃の食い込みに伴って芯線が自由に変形して圧縮力が緩和され、芯線を高圧縮状態で圧接することはできない。このため、芯線に非導電性の被膜が形成されている場合には、被膜を削り取ることができず、接触抵抗が高くなるおそれがある。   However, in the above-mentioned pressure contact connector, although the electric wire is held by the holding portion, the portion that is not in contact with the holding portion is free, so that the core wire is freely deformed as the pressure contact blade bites, and the compression force Is relaxed, and the core wire cannot be pressed in a highly compressed state. For this reason, when the non-conductive film is formed on the core wire, the film cannot be scraped off, and the contact resistance may be increased.

本発明は上記のような事情に基づいて完成されたものであって、高圧縮状態で芯線を圧接することにより、芯線の表面に形成された被膜を除去し、接触抵抗を安定させることを目的とする。   The present invention has been completed based on the above circumstances, and aims to remove the coating formed on the surface of the core wire and stabilize the contact resistance by pressing the core wire in a highly compressed state. And

本発明の圧接コネクタは、電線が圧入気味に挿入される保持溝を有する保持部材と、保持溝に近接して差し込まれる差込部を有し、この差込部における差し込み方向先端に圧接刃が形成された圧接端子と、差込部における圧接刃と反対側の端部を支持する一側本体部と保持部材を支持する他側本体部とがヒンジ部によって開閉可能に連結されてなり、一側本体部と他側本体部を閉塞することにより差込部が保持溝に差し込まれるハウジングと、保持溝の奥端部に設けられ、電線に圧接刃を食い込ませることで、保持溝に差し込まれた差込部との間で電線を狭圧する受け部とを備えた構成としたところに特徴を有する。   The press-connecting connector of the present invention has a holding member having a holding groove into which an electric wire is inserted in a press-fit manner, and an insertion portion to be inserted in the vicinity of the holding groove, and a press-contact blade is provided at the insertion direction tip of the insertion portion. The formed press contact terminal, the one side main body portion supporting the end opposite to the press contact blade in the insertion portion, and the other side main body portion supporting the holding member are connected by a hinge portion so as to be opened and closed. The housing is inserted into the holding groove by closing the side main body and the other side main body, and the inner end of the holding groove is inserted into the holding groove. It is characterized in that it has a configuration including a receiving portion for narrowing the electric wire between the inserted portion and the insertion portion.

このような構成によると、一側本体部と他側本体部とによって電線を挟み込むようにして閉塞すると、差込部によって電線が圧入気味に保持溝に挿入される。電線が受け部に至ると、圧接刃が電線に食い込むことで電線が差込部と受け部との間で狭圧される。そして、一側本体部と他側本体部が閉塞状態に至ると、芯線が高圧縮状態で圧接され、被膜を削り取ることができ、接触抵抗を安定させることができる。   According to such a configuration, when the electric wire is blocked by being sandwiched between the one-side main body portion and the other-side main body portion, the electric wire is inserted into the holding groove in a press-fit manner by the insertion portion. When the electric wire reaches the receiving portion, the press contact blade bites into the electric wire, so that the electric wire is narrowed between the insertion portion and the receiving portion. And when one side main-body part and the other side main-body part reach the obstruction | occlusion state, a core wire will be press-contacted in a highly compressed state, a film can be scraped off, and contact resistance can be stabilized.

本発明の実施の態様として、以下の構成が好ましい。
圧接端子は、差込部の両側縁の一方から一側に延出された一側案内壁と、同他方から他側に延出された案内壁とを備えて構成され、一側案内壁と他側案内壁が差込部を介して段差状に連結されており、保持部材は、一側案内壁と他側案内壁とに対面状態で装着され、電線は、一側案内壁と他側案内壁との間に形成された案内溝に挿入される構成としてもよい。
The following configuration is preferable as an embodiment of the present invention.
The press contact terminal includes a one-side guide wall extending from one side edge of the insertion portion to one side, and a guide wall extending from the other side to the other side. The other side guide wall is connected to the one side guide wall and the other side guide wall in a face-to-face state, and the electric wire is connected to the one side guide wall and the other side through the insertion portion. It is good also as a structure inserted in the guide groove formed between the guide walls.

このような構成によると、保持部材を一側案内壁と他側案内壁とに対面させるようにして装着することにより保持部材を圧接端子に対して位置決めすることができる。また、電線を案内溝に挿入することにより電線を圧接端子に対して位置決めすることができる。   According to such a configuration, the holding member can be positioned with respect to the press contact terminal by mounting the holding member so as to face the one side guide wall and the other side guide wall. Further, the electric wire can be positioned with respect to the press contact terminal by inserting the electric wire into the guide groove.

保持溝の奥端部には、差込部の差し込み方向と交差する方向に拡張することによって逃がし部が形成されており、電線は、逃がし部に嵌り込んだ状態で狭圧される構成としてもよい。
このような構成によると、電線を保持溝から逃がし部に嵌め込むことにより、電線を安定した状態で位置決めすることができ、圧接刃を電線の内部まで食い込ませることができる。これにより、接触抵抗を安定させることができる。
At the back end of the holding groove, a relief part is formed by extending in the direction intersecting with the insertion direction of the insertion part, and the electric wire may be configured to be compressed while being fitted in the relief part. Good.
According to such a configuration, the electric wire can be positioned in a stable state by fitting the electric wire into the escape portion from the holding groove, and the press contact blade can be bitten into the electric wire. Thereby, contact resistance can be stabilized.

圧接刃は円弧状をなしている構成としてもよい。
このような構成によると、圧接刃が電線により食い込みやすくなる。
The press contact blade may have a circular arc shape.
According to such a configuration, the press contact blade can easily bite into the electric wire.

本発明によれば、高圧縮状態で芯線を圧接することにより、芯線の表面に形成された被膜を除去し、接触抵抗を安定させることができる。   According to the present invention, by pressing the core wire in a highly compressed state, the coating formed on the surface of the core wire can be removed, and the contact resistance can be stabilized.

<実施形態>
本発明の実施形態を図1ないし図7の図面を参照しながら説明する。本実施形態の圧接コネクタ10は、図1に示すように、ハウジング20、一対の圧接端子30、保持部材40などを備えて構成されている。ハウジング20は合成樹脂製であって、待受け側本体部21と一対の蓋側本体部22とがそれぞれヒンジ部23によって連結された構成である。
<Embodiment>
An embodiment of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 1, the pressure contact connector 10 of the present embodiment includes a housing 20, a pair of pressure contact terminals 30, a holding member 40, and the like. The housing 20 is made of synthetic resin, and has a configuration in which a standby-side main body portion 21 and a pair of lid-side main body portions 22 are connected by hinge portions 23, respectively.

ヒンジ部23は可撓性を有し、図2に示すように、所定の間隔を空けて並列に配置された一対の可撓片部23Aを備えている。蓋側本体部22は、ヒンジ部23を介して待受け側本体部21に対して開閉可能に連結されている。なお、待受け側本体部21は本発明でいう「一側本体部」に対応し、蓋側本体部22は本発明でいう「他側本体部」に対応している。   The hinge portion 23 has flexibility, and includes a pair of flexible piece portions 23A arranged in parallel at a predetermined interval as shown in FIG. The lid side main body portion 22 is connected to the standby side main body portion 21 via the hinge portion 23 so as to be opened and closed. The standby-side main body 21 corresponds to “one-side main-body” in the present invention, and the lid-side main-body 22 corresponds to “other-side main-body” in the present invention.

蓋側本体部22におけるヒンジ部23と反対側の側縁部には、一対のロック爪24が所定の間隔を空けて設けられている。一方、待受け側本体部21には、両ロック爪24が嵌り込む一対のロック孔25が設けられている。蓋側本体部22を待受け側本体部21に対して閉塞した状態にすると、両ロック爪24が両ロック孔25に嵌り込み、ロック爪24の先端に設けられた係止突部24Aがロック孔25の孔縁部に係止することにより、蓋側本体部22が待受け側本体部21に対して閉塞状態に保持される。   A pair of lock claws 24 are provided at a predetermined interval on the side edge portion of the lid-side main body portion 22 opposite to the hinge portion 23. On the other hand, the standby-side main body portion 21 is provided with a pair of lock holes 25 into which both lock claws 24 are fitted. When the lid side main body portion 22 is closed with respect to the standby side main body portion 21, both lock claws 24 are fitted into both lock holes 25, and a locking projection 24A provided at the tip of the lock claw 24 is a lock hole. The lid side main body portion 22 is held in a closed state with respect to the standby side main body portion 21 by being engaged with the 25 hole edge portions.

蓋側本体部22には、保持部材40が立設されており、待受け側本体部21には、一対の圧接端子30が立設されている。両圧接端子30は、図2に示すように、基部31によって連結されている。このため、両圧接端子30に電線Wが接続されると、両電線Wは電気的に接続される。なお、基部31は、待受け側本体部21に対して圧入もしくはインサート成形されており、保持部材40は、蓋側本体部22に対して圧入もしくはインサート成形されている。   A holding member 40 is erected on the lid-side main body 22, and a pair of press contact terminals 30 are erected on the standby-side main body 21. The two press contact terminals 30 are connected by a base 31 as shown in FIG. For this reason, when the electric wire W is connected to both the press contact terminals 30, both the electric wires W are electrically connected. The base 31 is press-fitted or insert-molded with respect to the standby-side main body 21, and the holding member 40 is press-fitted or insert-molded with respect to the lid-side main body 22.

保持部材40は、金属製もしくは合成樹脂製とされており、横長略方形の断面形状をなす板状に構成されている。保持部材40は、図1の開放状態において蓋側本体部22の上面から上方に突出している。このため、ヒンジ部23を中心として蓋側本体部22を待受け側本体部21に閉じると、保持部材40は圧接端子30に対して上方から装着される。また、保持部材40の上部には、スリット状の保持溝41が形成されており、保持溝41の入口部分41Aは、徐々に間口が広くなるように形成されている。   The holding member 40 is made of metal or synthetic resin, and is configured in a plate shape having a horizontally long substantially square cross-sectional shape. The holding member 40 protrudes upward from the upper surface of the lid-side main body 22 in the opened state of FIG. For this reason, when the lid side main body portion 22 is closed to the standby side main body portion 21 with the hinge portion 23 as the center, the holding member 40 is attached to the press contact terminal 30 from above. In addition, a slit-like holding groove 41 is formed in the upper portion of the holding member 40, and an inlet portion 41A of the holding groove 41 is formed so that the frontage is gradually widened.

保持溝41は、図5に示すように、電線Wの径寸法よりも小さめの溝幅を有している。このため、電線Wは、図6に示すように、保持溝41に圧入気味で挿入される。保持溝41のエッジは面取りが施されており、電線Wの被覆W2は、保持溝41のエッジによって切断されないようになっている。また、保持溝41の奥端部には、保持溝41を幅方向両側に拡幅することによって横長の楕円形状をなす逃がし部42が形成されている。逃がし部42の面積は、電線Wの断面積と同じかこれよりやや小さめとされている。   As shown in FIG. 5, the holding groove 41 has a groove width smaller than the diameter dimension of the electric wire W. For this reason, as shown in FIG. 6, the electric wire W is inserted into the holding groove 41 with a press fit. The edge of the holding groove 41 is chamfered, and the coating W <b> 2 of the electric wire W is not cut by the edge of the holding groove 41. In addition, a relief portion 42 having a horizontally long elliptical shape is formed at the back end of the holding groove 41 by widening the holding groove 41 on both sides in the width direction. The area of the escape portion 42 is the same as or slightly smaller than the cross-sectional area of the electric wire W.

圧接端子30は、図3に示すように、金属板材を打ち抜いた後に曲げ加工することによって形成されており、一対の案内壁32A,32Bが差込部33を介して段差状に配置された構成である。差込部33の上縁には、円弧状をなす圧接刃35が形成されている。差込部33の高さは、両案内壁32A,32Bの高さのほぼ半分とされており、両案内壁32A,32Bの略下半分が差込部33によって連結されている。   As shown in FIG. 3, the press contact terminal 30 is formed by punching a metal plate and then bending it, and a pair of guide walls 32 </ b> A and 32 </ b> B are arranged in a stepped manner via the insertion portion 33. It is. A pressing blade 35 having an arc shape is formed on the upper edge of the insertion portion 33. The height of the insertion portion 33 is approximately half of the height of both guide walls 32A, 32B, and the substantially lower half of both guide walls 32A, 32B is connected by the insertion portion 33.

以下においては図示右側の圧接端子30を代表として説明するものとし、図1に示すように、両案内壁32A,32Bのうち図示左側の案内壁を一側案内壁32Aとし、図示右側の案内壁を他側案内壁32Bとする。両案内壁32A,32Bは、電線Wの軸線方向に対面しない配置とされている。両案内壁32A,32Bの間には、案内溝34が形成されている。すなわち、案内溝34は、一側案内壁32Aの右側面と他側案内壁32Bの左側面と差込部33の上面とによって構成されている。なお、案内溝34の入口部分34Aは、徐々に間口が広くなるように形成されている。   In the following description, the pressure contact terminal 30 on the right side of the figure will be described as a representative. As shown in FIG. 1, the left side guide wall of the guide walls 32A and 32B is referred to as the one side guide wall 32A, and the right side guide wall in the figure is shown. Is the other side guide wall 32B. Both guide walls 32 </ b> A and 32 </ b> B are arranged so as not to face in the axial direction of the electric wire W. A guide groove 34 is formed between the guide walls 32A and 32B. That is, the guide groove 34 is configured by the right side surface of the one side guide wall 32 </ b> A, the left side surface of the other side guide wall 32 </ b> B, and the upper surface of the insertion portion 33. The entrance portion 34A of the guide groove 34 is formed so that the frontage gradually becomes wider.

両案内壁32A,32Bは、図1に示す電線Wの軸線方向から見ると差込部33の板厚一枚分の間隔を空けて配置されている。また、両案内壁32A,32Bは、図2に示す上側から見ると保持部材40の板厚一枚分の間隔を空けて配置されている。差込部33は、図1に示すように、保持部材40と幅方向に対応して配置されている。このため、蓋側本体部22を待受け側本体部21に閉塞すると、図4に示すように、保持部材40は両案内壁32A,32Bの間に嵌り込み、差込部33が保持溝41に進入する。   Both guide walls 32A and 32B are arranged with an interval of one sheet thickness of the insertion portion 33 when viewed from the axial direction of the electric wire W shown in FIG. Moreover, when viewed from the upper side shown in FIG. 2, both guide walls 32 </ b> A and 32 </ b> B are arranged with an interval corresponding to one plate thickness of the holding member 40. The insertion part 33 is arrange | positioned corresponding to the holding member 40 and the width direction, as shown in FIG. For this reason, when the lid side main body portion 22 is closed to the standby side main body portion 21, the holding member 40 is fitted between the guide walls 32A and 32B and the insertion portion 33 is inserted into the holding groove 41 as shown in FIG. enter in.

ここで、差込部33の板厚は、保持溝41の溝幅とほぼ同じかこれよりやや小さめとされているため、保持部材40を圧接端子30に対して保持溝41の溝幅方向に位置決め状態で装着できる。また、保持部材40の正面が一側案内壁32Aの背面と密接し、かつ、保持部材40の背面が他側案内壁32Bの正面と密接した状態で保持部材40を装着することにより、保持部材40を圧接端子30に対して電線Wの軸線方向に位置決め状態で装着できる。   Here, since the thickness of the insertion portion 33 is substantially the same as or slightly smaller than the groove width of the holding groove 41, the holding member 40 is placed in the groove width direction of the holding groove 41 with respect to the press contact terminal 30. Can be mounted in a positioned state. Further, the holding member 40 is mounted in a state where the front surface of the holding member 40 is in close contact with the back surface of the one side guide wall 32A and the back surface of the holding member 40 is in close contact with the front surface of the other side guide wall 32B. 40 can be attached to the press contact terminal 30 in a positioning state in the axial direction of the electric wire W.

ところで、本実施形態の電線Wは、いわゆるアルミ電線であって、芯線W1の材料としてアルミもしくはアルミ合金が用いられている。アルミ電線は、銅電線と比較して表面が酸化されやすく、非導電性の被膜が形成されやすいため、銅電線と同じような圧接方法では被膜を十分に削り取ることができず、接触抵抗が増大するおそれがある。このため、本実施形態ではアルミ電線の被膜を除去するために、様々な改善が施されている。以下、その改善点について説明する。   By the way, the electric wire W of this embodiment is what is called an aluminum electric wire, Comprising: Aluminum or aluminum alloy is used as a material of the core wire W1. Aluminum wires are more susceptible to oxidation than non-copper wires, and non-conductive coatings are easily formed. As a result, it is not possible to scrape the coating sufficiently with the same pressure welding method as copper wires, increasing contact resistance. There is a risk. For this reason, in this embodiment, in order to remove the coating of the aluminum electric wire, various improvements are made. Hereinafter, the improvements will be described.

保持溝41の奥端部には、受け部43が形成されている。図5に示すように、電線Wを案内溝34の入口部分34Aに載置した後に、電線Wを保持溝41に圧入していくと、図6に示すように、芯線W1が受け部43に接触する。ここから電線Wをさらに押し込むと、図7に示すように、電線Wが逃がし部42に嵌り込むとともに、圧接刃35が電線Wに食い込むことになる。これにより電線Wは、差込部33と受け部43とによって上下方向から狭圧され、高圧縮状態で圧接される。   A receiving portion 43 is formed at the inner end of the holding groove 41. As shown in FIG. 5, when the electric wire W is press-fitted into the holding groove 41 after the electric wire W is placed on the inlet portion 34 </ b> A of the guide groove 34, the core wire W <b> 1 enters the receiving portion 43 as shown in FIG. 6. Contact. When the electric wire W is further pushed in from here, the electric wire W fits into the escape portion 42 and the press contact blade 35 bites into the electric wire W as shown in FIG. Thereby, the electric wire W is narrowly pressed from the up-down direction by the insertion part 33 and the receiving part 43, and is press-contacted in a highly compressed state.

このように電線Wが狭圧される理由は、電線Wが逃がし部42に嵌り込んで保持溝41が差込部33により塞がれるためであり、電線Wの逃げ場がなくなった状態で圧接刃35が電線Wに差し込まれ、圧接刃35が電線Wに食い込むことで電線Wに非常に高い圧縮力が負荷される。これにより芯線W1は、圧接刃35に高圧縮状態で圧接され、芯線W1の表面に形成された被膜が除去されるとともに、芯線W1を構成する素線および圧接刃35が互いに凝着し、これらが導通可能に接続される。   The reason why the electric wire W is narrowed in this way is that the electric wire W is fitted into the escape portion 42 and the holding groove 41 is blocked by the insertion portion 33, and the press contact blade is in a state where the escape place of the electric wire W is lost. 35 is inserted into the electric wire W, and the press contact blade 35 bites into the electric wire W, whereby a very high compressive force is applied to the electric wire W. As a result, the core wire W1 is pressed against the press contact blade 35 in a highly compressed state, the coating formed on the surface of the core wire W1 is removed, and the strands constituting the core wire W1 and the press contact blade 35 adhere to each other. Are connected in a conductive manner.

本実施形態は以上のような構成であって、続いてその作用を説明する。まず、図5に示すように、電線Wを案内溝34の入口部分34Aに載置し、ヒンジ部23を中心として蓋側本体部22を待受け側本体部21に向けて閉じる。すると、保持溝41に差込部33が差し込まれ、電線Wが保持溝41に圧入される。これと併行して電線Wは、案内溝34によって上下方向に案内されるため、電線Wを圧接端子30に対して位置決めすることができる。なお、電線Wを保持溝41に圧入する過程において被覆W2は、保持溝41のエッジや案内溝34のエッジによって切断されない。   The present embodiment is configured as described above, and its operation will be described subsequently. First, as shown in FIG. 5, the electric wire W is placed on the inlet portion 34 </ b> A of the guide groove 34, and the lid-side main body portion 22 is closed toward the standby-side main body portion 21 with the hinge portion 23 as the center. Then, the insertion portion 33 is inserted into the holding groove 41, and the electric wire W is press-fitted into the holding groove 41. In parallel with this, since the electric wire W is guided in the vertical direction by the guide groove 34, the electric wire W can be positioned with respect to the press contact terminal 30. In the process of press-fitting the electric wire W into the holding groove 41, the coating W <b> 2 is not cut by the edge of the holding groove 41 or the edge of the guide groove 34.

電線Wの圧入が進み、図6に示すように、電線Wが受け部43に接触した後、さらに電線Wを受け部43に押し込むと、電線Wは逃がし部42に嵌り込む。このとき、電線Wは、逃がし部42の形状に沿って横長楕円形状に変形するため、保持部材40に対して安定した状態で位置決めされる。これと同時に、保持溝41は、差込部33によって塞がれた状態となるため、電線Wは保持溝41側に逃げることができなくなり、逃がし部42において逃げ場を失うことになる。   As the press-fitting of the electric wire W proceeds and the electric wire W comes into contact with the receiving portion 43 as shown in FIG. 6, when the electric wire W is further pushed into the receiving portion 43, the electric wire W is fitted into the escape portion 42. At this time, the electric wire W is deformed into a horizontally long elliptical shape along the shape of the relief portion 42, and thus is positioned in a stable state with respect to the holding member 40. At the same time, since the holding groove 41 is closed by the insertion portion 33, the electric wire W can no longer escape to the holding groove 41 side and the escape portion 42 loses the escape place.

そして、逃げ場を失った電線Wに圧接刃35を食い込ませると、図7に示すように、電線Wが差込部33と受け部43とによって上下方向から狭圧される。圧接刃35の食い込みに伴って圧縮力が発生し、芯線W1は、圧接刃35に対して高圧縮状態で圧接され、芯線W1の表面に形成された被膜が除去されるとともに、芯線W1を構成する素線および圧接刃35が互いに凝着し、接触抵抗が安定した状態で芯線W1と圧接刃35とが導通可能に接続される。こうして、両圧接端子30にそれぞれ接続された両電線Wが電気的に接続される。この状態では両ロック爪24が両ロック孔25に嵌合し、両係止突部24Aが両ロック孔25の孔縁部に係止することにより、待受け側本体部21と蓋側本体部22とが閉塞状態に保持される。   Then, when the press contact blade 35 is bitten into the electric wire W that has lost its escape, the electric wire W is narrowed in the vertical direction by the insertion portion 33 and the receiving portion 43 as shown in FIG. A compressive force is generated as the press contact blade 35 bites in, and the core wire W1 is pressed against the press contact blade 35 in a highly compressed state, and the coating formed on the surface of the core wire W1 is removed and the core wire W1 is configured. The core wire W1 and the press contact blade 35 are connected to each other in a conductive state in a state in which the element wire and the press contact blade 35 adhere to each other and the contact resistance is stable. Thus, the two electric wires W respectively connected to the two press contact terminals 30 are electrically connected. In this state, both lock claws 24 are fitted into both lock holes 25, and both locking projections 24A are locked to the hole edges of both lock holes 25, so that the standby side main body portion 21 and the lid side main body portion 22 are engaged. Are held in a closed state.

以上のように本実施形態では、電線Wを逃がし部42に嵌め込んだ上で、保持溝41を差込部33で塞ぎ、電線Wの逃げ場をなくした上で圧接刃35を電線Wに食い込ませるようにしたから、電線Wを差込部33と受け部43との間で上下方向から狭圧することができる。これにより、電線Wの芯線W1と圧接刃35を高圧縮状態で圧接することができ、芯線W1の表面に形成された被膜を除去し、接触抵抗を安定させることができる。   As described above, in the present embodiment, after the electric wire W is fitted into the escape portion 42, the holding groove 41 is closed with the insertion portion 33, and the escape area of the electric wire W is eliminated, and the press contact blade 35 is bitten into the electric wire W. Therefore, the electric wire W can be narrowed between the insertion portion 33 and the receiving portion 43 in the vertical direction. Thereby, the core wire W1 of the electric wire W and the press-contacting blade 35 can be pressed in a highly compressed state, the coating formed on the surface of the core wire W1 can be removed, and the contact resistance can be stabilized.

また、圧接端子30を段差状に形成し、両案内壁32A,32Bによって保持部材40を挟み込むとともに、保持溝41によって差込部33を挟み込むようにしたから、保持部材40を圧接端子30に対して位置決め状態で装着することができる。また、電線Wを案内溝34によって案内されるようにしたから、電線Wを圧接端子30に対して位置決めできる。さらに、逃がし部42を設けたから、電線Wを安定した状態で位置決めすることができる。また、圧接刃35を円弧状に形成したから、圧接刃35を電線Wに食い込ませやすくできる。   In addition, the press contact terminal 30 is formed in a stepped shape, the holding member 40 is sandwiched between the guide walls 32A and 32B, and the insertion portion 33 is sandwiched by the holding groove 41. Can be mounted in the positioning state. Further, since the electric wire W is guided by the guide groove 34, the electric wire W can be positioned with respect to the press contact terminal 30. Furthermore, since the escape portion 42 is provided, the electric wire W can be positioned in a stable state. Further, since the press contact blade 35 is formed in an arc shape, the press contact blade 35 can be easily bited into the electric wire W.
