Description of the Related Art Conventionally, there is a terminal fitting disclosed in Japanese Utility Model Application Laid-Open No. 60-71082 as a terminal fitting for connecting by crimping an electric wire having a rubber plug fitted over the rubber plug. At the rear end of the terminal fitting, a crimping portion in the form of a pair of caulking pieces rising from the bottom wall is formed, and a rubber plug externally fitted to the electric wire is placed on the bottom wall, and the rubber plug is By crimping the caulking piece around, the electric wire is crimped to the crimping portion together with the rubber stopper.

起部分にゴム栓の外周を引っ掛けるようになっていた。In this type of terminal fitting, when the electric wire is pulled, there is a concern that the rubber stopper may be elastically deformed and come off from the crimping piece. As a countermeasure, a means for hooking the rubber stopper on the crimping portion is provided. Forming is being done. As a means for this, in the above-mentioned conventional terminal fitting, the crimping portion is partially cut and raised inward (to the side of the rubber plug), and the outer periphery of the rubber plug is hooked on the cut and raised portion.

を破ってしまう虞がある。However, since the edge of the hook formed by cutting and raising has a sharp edge, the edge may damage the rubber plug. In particular, in the case of miniaturized terminal fittings, since the thickness of the rubber plug is reduced with the miniaturization, the edge portion is not limited to simply scratching the outer periphery of the rubber plug, but breaking the rubber plug. There is a possibility that it will end up.

Is concerned. However, in the present invention, since the hook portion has a concave shape,
The amount of crushing of the rubber plug by the hook portion is reduced, and there is no possibility that the rubber plug is broken even if the rubber plug is thin. [Invention of claim 5] Since the outer surface of the insulation barrel does not have to partially protrude, the diameter of the entire insulation barrel is smaller than that in which the portion where the hook portion is formed protrudes to the outer peripheral side. It is getting smaller.

っても破れる虞がない。Further, if the hook portion is formed to protrude from the close contact portion when the rubber stopper 25 is thin, there is a concern that the rubber stopper 25 is crushed excessively by the protruding portion and the rubber stopper 25 is broken. Is done. However, in the present embodiment, since the hook portions 18F and 18R are recessed, the amount of crushing of the rubber plug 25 by the hook portions 18F and 18R is reduced, and there is no possibility that the rubber plug 25 is broken even if the rubber plug 25 is thin.

図７を参照して説明する。Further, since the hook portions 18F and 18R are formed so that the thickness thereof is smaller than the thickness of the close contact portion 17, the outer surface of the insulation barrel 16 does not have to partially protrude. . Therefore, the diameter of the entire insulation barrel 16 is smaller than that in which the portion where the hooking portion is formed protrudes toward the outer peripheral side. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG.
