Description

本発明は、スプライス用圧接端子および該スプライス用圧接端子を用いたスプライス電線の防水構造に関し、特に、複数の電線の端末集中スプライスまたは継ぎ出し仕様のスプライスに用いる圧接端子に関するものである。   The present invention relates to a splice pressure contact terminal and a waterproof structure of a splice wire using the splice pressure contact terminal, and more particularly to a pressure contact terminal used for terminal concentrated splice of multiple wires or splicing of splicing specifications.

この種の複数の電線のスプライス接続に用いる接続具として、例えば、実公昭53−23564号公報に、図15に示す接続具が提供されている。
この接続具1は、互いに対称形状をなす接合片1a、1bを連結片1cを介して開閉自在に連結し、一方の接合片1aの内側に形成した2条の溝1d、1eに互いにスプライス接続する2本の電線w1、w2をはめ込んだ後、該接合片1aに他方の接合片1bを被せることにより、該他方の接合片1bの内側に形成した圧接刃1fの切欠部1gを電線w1、w2に絶縁被覆にそれぞれ食い込み圧入して芯線と導通させて両電線w1、w2をスプライス接続するものである。
As a connection tool used for the splicing connection of a plurality of electric wires of this type, for example, a connection tool shown in FIG. 15 is provided in Japanese Utility Model Publication No. 53-23564.
This connecting device 1 connects joint pieces 1a and 1b that are symmetrical to each other so as to be openable and closable via a connecting piece 1c, and is spliced to two grooves 1d and 1e formed inside one joint piece 1a. After fitting the two electric wires w1 and w2 to be covered, the notched portion 1g of the press contact blade 1f formed inside the other joining piece 1b is covered with the other joining piece 1b by covering the joining piece 1a with the electric wire w1. Each of the electric wires w1 and w2 is spliced by being inserted into w2 by press-fitting into the insulating coating and electrically connected to the core wire.

前記接続具1は、電線w1、w2を溝1d、1eにセットするときに位置決めや仮固定の手段がないため、電線w1、w2が位置ずれしやすく、特に継ぎ出し仕様のスプライス接続の場合は、所定位置に圧接刃1fを圧入できずに接続不良等を生じる虞れがある。   Since the connector 1 has no means for positioning or temporarily fixing the wires w1 and w2 in the grooves 1d and 1e, the wires w1 and w2 are likely to be displaced, particularly in splicing connection with splicing specifications. The press contact blade 1f cannot be press-fitted into a predetermined position, which may cause a connection failure or the like.

また、特開2005−149936号公報で提供されている図16に示すコネクタ2では、複数の電線を固定保持するホルダ2a、2bと、これらホルダ2a、2bを装着するハウジング2cとを備え、ハウジング2cには圧接端子部2eを有するバスバー2dをインサートモールド成形等により一体に備えると共に、該圧接端子部2eを、ハウジングの長さ方向中央部に形成した位置決め凸部2fを挟んだ両側に突出させている。   Further, the connector 2 shown in FIG. 16 provided in Japanese Patent Application Laid-Open No. 2005-149936 includes holders 2a and 2b for fixing and holding a plurality of electric wires, and a housing 2c for mounting these holders 2a and 2b. The bus bar 2d having the press contact terminal portion 2e is integrally provided by insert molding or the like, and the press contact terminal portion 2e is protruded on both sides of the positioning convex portion 2f formed at the center in the longitudinal direction of the housing. ing.

このコネクタ2は、電線w3、w4をそれぞれ固定保持したホルダ2a、2bを前記ハウジング2cに装着することにより、各電線w3、w4を圧接端子部2eのスリット2gに圧入して芯線とバスバー2dとを導通させるものであるが、このとき、ホルダ2a、2bの端部を前記位置決め凸部2fに当接させることによりホルダ2a、2bのハウジング2cに対する位置決めを行う構造になっている。
前記コネクタ2を用いると、前記位置決め凸部2fにより電線の位置揃えが可能であり、圧接位置の位置ずれを防止できるが、構造的に複雑であるため製造コストが高くなる点に課題がある。
In this connector 2, the holders 2a and 2b, which hold and hold the electric wires w3 and w4, respectively, are attached to the housing 2c, so that the electric wires w3 and w4 are press-fitted into the slits 2g of the press contact terminal portion 2e. At this time, the holders 2a and 2b are positioned with respect to the housing 2c by bringing the end portions of the holders 2a and 2b into contact with the positioning projections 2f.
When the connector 2 is used, it is possible to align the electric wires by the positioning projections 2f and prevent the displacement of the press contact position, but there is a problem in that the manufacturing cost is increased due to the structural complexity.

更に、防水スプライス構造としては、特開2001−57252号公報に、図17に示すように、複数の電線3の端末を1箇所に集中させ、圧接端子4に圧接接続させて端末集中スプライス部5を形成し、該スプライス部5をシール剤7を充填している絶縁樹脂製のキャップ6内に挿入し、電線間の隙間にシール剤7を浸透させてスプライス部5に防水処理を施している構造が提供されている。   Furthermore, as a waterproof splice structure, as shown in FIG. 17 in Japanese Patent Laid-Open No. 2001-57252, the terminals of a plurality of electric wires 3 are concentrated at one place and are press-contacted to the press-contact terminals 4 to be terminal-concentrated splice portions 5. The splice part 5 is inserted into a cap 6 made of an insulating resin filled with a sealant 7, and the sealant 7 is infiltrated into the gaps between the wires so that the splice part 5 is waterproofed. Structure is provided.

この防水スプライス構造においても、圧接端子4に電線の圧接位置を合わせる機能がないため、作業中に圧接位置のズレを生じる虞があり、接続信頼性において改良の余地がある。また、この防水スプライス構造は、継ぎ出し仕様のスプライス部には適用できない。   Even in this waterproof splice structure, since there is no function of aligning the press-contact position of the electric wire with the press-contact terminal 4, there is a risk of displacement of the press-contact position during work, and there is room for improvement in connection reliability. In addition, this waterproof splice structure cannot be applied to spliced parts with splicing specifications.

以下、本発明の実施形態を図面を参照して説明する。
図1乃至図4に、本発明の参考第1実施形態に係るスプライス用圧接端子10を示す。 前記圧接端子10は、複数の電線80の端末集中スプライス接続に用いる端子であり、1枚の導電性金属板を折曲して、対向する側板11、12と該側板11、12の下端を連続する底板13とを備えた凹形状に形成している。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4, it shows a splice press-connecting terminal 10 according to the reference first embodiment of the present invention. The press contact terminal 10 is a terminal used for terminal concentrated splicing connection of a plurality of electric wires 80, and one conductive metal plate is bent and the opposing side plates 11, 12 and the lower ends of the side plates 11, 12 are continuously connected. The bottom plate 13 is formed in a concave shape.

前記一方の側板11は電線80を挿入する圧接溝14を設けた電線保持壁11とし、他方の側板12は電線80の先端を当接させる突き当て壁としている。
前記圧接溝14は電線保持壁11の上端からU形状に切り込んで形成し、該電線保持壁11の長さ方向に間隔をあけて複数個設けている。各圧接溝14を挟んで対向する両側部の先端は、各電線80の絶縁被覆81に切り込む圧接刃部15としている。
前記突き当て壁12の底板13からの高さh2は、図1および図2(B)に示すように、前記電線保持壁11の底板13からの高さh1よりも高く設定している。
The one side plate 11 is an electric wire holding wall 11 provided with a pressure contact groove 14 into which the electric wire 80 is inserted, and the other side plate 12 is an abutting wall against which the tip of the electric wire 80 abuts.
The pressure contact groove 14 is formed by cutting a U shape from the upper end of the wire holding wall 11, and a plurality of the pressure contact grooves 14 are provided at intervals in the length direction of the wire holding wall 11. The tips of both side portions facing each other with the respective pressure contact grooves 14 are formed as pressure contact blade portions 15 cut into the insulating coating 81 of each electric wire 80.
The height h2 of the abutting wall 12 from the bottom plate 13 is set to be higher than the height h1 of the electric wire holding wall 11 from the bottom plate 13 as shown in FIGS.

このスプライス用圧接端子10を用いて複数の電線80をスプライス接続するときは、まず、図2(A)(B)に示すように、これらの電線80の先端を、圧接端子10の前記電線保持壁11を越えて突き当て壁12の内側面12aの上部に当接させ、各電線80の先端位置を揃えて位置合わせをする。
次に、図3(A)(B)に示すように、電線80の先端を突き当て壁12に当接させた状態のまま、各電線80を下方へ押して電線保持壁11の各圧接溝14に圧入する。
これにより、図4に示すように、各圧接溝14の両側の前記圧接刃部15が電線80の絶縁被覆81に食い込んで内部の芯線82に接触し、端子10と各電線80とが導通して電線80の端末集中スプライスを形成する。

As a result, as shown in FIG. 4, the press contact blade portions 15 on both sides of each press contact groove 14 bite into the insulation coating 81 of the electric wire 80 and contact the inner core wire 82, and the terminal 10 and each electric wire 80 are electrically connected. Thus, a terminal concentrated splice of the electric wire 80 is formed.

このように、前記スプライス用圧接端子10を用いると、互いにスプライス接続する電線80を各圧接溝14に圧入する前に、先端を突き当て壁12に当接させるという容易な作業で電線80の圧接位置を揃えることができるため、圧接位置のズレを防ぎ、所定の圧接位置に正確に圧接刃部15を食い込ませることによって、接続不良等の不具合を防止でき、接続信頼性を高めることができる。
また、電線の位置合わせと圧接作業を容易な連続作業で行うことができるため、作業性も向上する。
さらに、前記圧接端子10の構造は簡素であるため、製造コストを低く抑えることができる。
Thus, when the splicing contact terminal 10 is used, the wire 80 can be pressed by the easy operation of abutting the tip against the abutting wall 12 before press-fitting the wires 80 to be spliced to each other. Since the positions can be aligned, the displacement of the press contact position can be prevented, and the press contact blade portion 15 can be inserted into the predetermined press contact position accurately, thereby preventing problems such as poor connection and improving connection reliability.
In addition, the workability is improved because the positioning and press-contacting operation of the electric wires can be performed by an easy continuous operation.
Furthermore, since the structure of the press contact terminal 10 is simple, the manufacturing cost can be kept low.

The wall portion 69 is opposed, and the one pressing wall portion 68 is opposed to the other pressure contact groove 65. The tips of both side portions facing each other with the respective pressure contact grooves 64 (65) interposed therebetween are pressure contact blade portions 66 (67) cut into the insulating coating of the electric wire.
