外れるという問題を生じる。Problems that Hatsushi tries to solve In the conventional fixing structure of the wire seal rubber l mentioned above, the claw part 4 of the terminal 3 is attached to the outer periphery of the wire seal rubber l.
However, since the wire seal rubber 1 is made of a soft supple material, most of the crimping force of the claw portion 4 is absorbed by the wire seal rubber 1, and it is difficult to reach the electric wire 6 inside the wire seal rubber 1. Therefore, since the caulking force is not sufficiently applied to the internal wire 6, when an external force (for example, a force that bends the wire 6) is applied near the wire seal rubber attachment part of the wire 6, the wire 6 A problem arises in that the S:11 slides inside the wire seal rubber 1 and comes off from the S:11 element 3.
そこで本発明は、電線が端子から外れるのを確実に防止
し得るワイヤシールラバーの固定構造を提供せんとする
ものである。SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a wire seal rubber fixing structure that can reliably prevent the wire from coming off the terminal.

Means for Solving the Problems The present invention provides a wire in which a wire seal rubber is fitted around the outer periphery of an electric wire, and a claw portion of a terminal is caulked onto the outer periphery of the wire seal rubber. In the seal rubber fixing structure, a notch is provided in a part of the caulking portion of the wire seal rubber, and the claw portion is caulked by straddling the wire seal rubber and the electric wire exposed through the notch. This is what I did.

実施例
以下、本発明の一実施例を第１，２図に払づいて説明す

形成されている。In Fig. 1.2, the wire seal rubber l is formed into a cylindrical shape by silicone rubber or the like, similar to the conventional one shown in Fig. 3 and subsequent drawings, and has a sealing part 2 and a caulking part 5 on its outer periphery. is provided. The seal part 2 is provided with a pair of flanges 7 to prevent it from coming off, and the part sandwiched between the pair of flanges 7 is fitted into a hole in a casing (not shown), etc., for leading in electric wires. There is. The caulking portion 5 has a notch 8 formed on its outer periphery at a portion (the upper portion in the figure) where the tip of the claw portion 4 of the terminal 3 is positioned during caulking.
尚、電線６、及び、端子３は第３図以下の図面に示した
ものと同様の構成となっている。Incidentally, the electric wire 6 and the terminal 3 have the same structure as shown in the drawings from FIG. 3 onwards.
このような部材構戊において、電線６、ワイヤシールラ
バーｌ１端子３の二者は次のようにして固定する。In such a member structure, the electric wire 6 and the wire seal rubber l1 terminal 3 are fixed in the following manner.
まず、電線６の外周部にワイヤシールラバー１を密着咲
合し、この状態において電線６を端子３に電気的に接続
すると共に、端子３の爪部４をワイヤシールラバーｌの
彼かしめ部５上にかしめる。First, the wire seal rubber 1 is closely attached to the outer periphery of the wire 6, and in this state, the wire 6 is electrically connected to the terminal 3, and the claw portion 4 of the terminal 3 is attached to the crimp portion 5 of the wire seal rubber l. Caulk the top.

シールラバー１の彼かしめ部５と電線６の外周面にまた
がってかしめられることになる。At this time, unlike the conventional one shown in the drawings from FIG. It is pressed against the outer peripheral surface of 6. Therefore, the claw portion 4 of the terminal 3 is caulked across the caulking portion 5 of the wire seal rubber 1 and the outer peripheral surface of the electric wire 6.

ても電線６は端子３から外れなくなる。In this way, the claw part 4 of the terminal 3 is made of wire seal rubber tar.
Since the electric wire 6 and the terminal 3 are caulked directly to the outer circumferential surface of the electric wire 6 instead of using a lever, the electric wire 6 and the terminal 3 are firmly and reliably fixed. As a result, even if an external force (for example, a force that bends the wire 6) is applied to the vicinity of the wire seal rubber attachment portion of the IJt 6, the wire 6 will not come off from the terminal 3.
