本発明は、ワイヤーハーネスの止水部形成方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for forming a water stop portion of a wire harness.
自動車内等の電気配線に使用するワイヤーハーネスは多
数本の電線を束ねて構成される。このためワイヤーハー
ネスに水が浸入した場合、その水が電線間の隙間を通っ
て長手方向に伝わりやすく、電線間を伝わった水は電線
の端末に取り付けられたコネクタの端子間をショートさ
せる等の問題がある。Wire harnesses used for electrical wiring in automobiles, etc. are constructed by bundling together a large number of electric wires. For this reason, if water enters the wire harness, the water tends to travel in the longitudinal direction through the gaps between the wires, and the water that travels between the wires can cause short-circuits between the terminals of the connectors attached to the ends of the wires. There's a problem.
従来、ワイヤーハーネスの電線間を水が伝わらないよう
にする手段としては、吸水膨潤材料を水溶性の包装材で
包み、これを電線間に介在させて、ワイヤーハーネスの
止水部とすることが知られている（実開昭６２−８１３
２０号公報）。Conventionally, as a means to prevent water from transmitting between the wires of a wire harness, it is possible to wrap a water-absorbing and swelling material in a water-soluble packaging material and interpose it between the wires to use it as a water-stop part of the wire harness. Known (Jitsukai 62-813
Publication No. 20).
しかしこれは、吸水膨潤材料を包装材で包んで電線間に
介在させる構造であるため、電線間には依然として隙間
が残り、水溶性の包装材に触れることなく電線間を水が
伝わるおそれがあった。However, since this is a structure in which the water-absorbing and swelling material is wrapped in a packaging material and interposed between the wires, gaps still remain between the wires, and there is a risk that water may be transmitted between the wires without touching the water-soluble packaging material. Ta.
そこで電線間に隙間ができないように電線間に直接防水
シール材を充填する構造が考えられた。Therefore, a structure was devised in which a waterproof sealing material is directly filled between the wires to prevent gaps between the wires.

填するようにしている。Conventionally, when filling waterproof sealant 2 directly between electric wires, waterproof sealant 2 is applied to the outer periphery of wire harness l using manual gun 3, as shown in FIG. As shown in FIG. 6, a vinyl tape 4 is wrapped around the outer periphery of the electric wire, and the waterproof sealing material 2 is filled between the electric wires by pressing the vinyl tape 4 by hand.
しかしこのような方法では、防水シール材をワイヤーハ
ーネスの中心部まで充填することが難しく、このため防
水特性が不安定であるという問題がある。However, with this method, it is difficult to fill the waterproof sealing material to the center of the wire harness, and therefore there is a problem that the waterproof properties are unstable.

とを特徴とする。The present invention provides a method for forming a waterproof sealant in a wire harness that solves the problems of the prior art as described above. The tip of the jig is inserted between the electric wires constituting the wire harness, and then the waterproof sealing material is extruded from the extrusion hole and filled between the electric wires.
このように先端部周壁に押出孔を設けた防水シール材注

確実に防水シール材を充填することが可能となり、防水
性能を向上させることができる。By using a waterproof sealant pouring jig with an extrusion hole in the peripheral wall of the tip, it is possible to reliably fill the waterproof sealant into the center of the wire harness, improving waterproof performance. .
以下、本発明の実施例を図面を参照して詳細に説明する
。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

is thick enough to be easily inserted between the wires of a wire harness, and a plurality of extrusion holes 7 are formed in its peripheral wall. The number and size of the extrusion holes 7 are appropriately selected depending on the thickness of the wire harness.

のでもよいし、電動式のものであってもよい。As shown in FIG. 2, this waterproof sealant injection jig 5 inserts the tip 6 between the electric wires of the wire harness l, extrudes the waterproof sealant 2 from the extrusion hole 7, and then inserts the waterproof sealant 2 between the electric wires. It is filled with Note that the means for pushing out the waterproof sealing material in the injection jig 5 may be a manual type shown in FIG. 5, or an electric type.
このようにワイヤーハーネス１内に位置する押出孔７か
ら防水シール材２を押し出せば、電線間に確実に防水シ
ール材を充填することができる。By extruding the waterproof sealant 2 from the extrusion hole 7 located in the wire harness 1 in this manner, the waterproof sealant can be reliably filled between the electric wires.

入治具の先端部６が挿入できるようになっている。FIG. 3 shows another embodiment of the present invention, which differs from the previous embodiment in that a waterproof sealant is applied to the outer periphery of the wire harness l near the position where the tip 6 of the waterproof sealant injection jig 5 is inserted. This is because the leak prevention device 8 of No. 2 was installed. The leakage prevention device 8 has a jig insertion hole 9 and a wire harness insertion hole lO.
It is a two-split rubber or plastic molded product having a shape, and the distal end 6 of the injection jig can be inserted into the wire harness 1 while it is attached to the outer periphery of the wire harness 1.

。This is because check holes 11 are provided at both ends. Providing such a check hole 11 has the advantage that if filling is continued until the waterproof sealing material 2 leaks out from the check hole 11, it can be detected that the waterproof sealing material 2 is sufficiently filled.
なお漏れ防止具８は、ゴムまたはプラスチックの成形品
だけでなく、単なるテープ巻きによっても構成できる。Note that the leakage prevention device 8 can be constructed not only from a molded product of rubber or plastic, but also from a simple tape wrapping.
