As shown in FIG. 4b, which is a vertical cross-sectional view of FIG. 4A and a Rollo cross-sectional view of FIG. 3
When the small diameter portion C1 of the rubber stopper C' inserted into the covered wire B is tightened, the cross section of that portion becomes as shown in the sectional view of FIG. That is, the opposing caulking piece tips a 3 ″ of the caulking portion a 3 are caulked and crimped to the small diameter portion C 1 of the rubber plug C′ and closely engage with the circumferential surface of the rubber stopper C′, but the caulking portion
The surface C 2 ′ of the rubber stopper that comes into contact with the base a 3 ′ of a 3 is pressed against the smooth curved base a 3 ′ and becomes a smooth curved surface.
When the rubber stopper C' is pulled in the direction of the arrow L by some external factor, or when the electric wire B is bent in the direction of the arrow L' (the direction opposite to the surface C 2 ' of the rubber stopper), the base The rubber plug surface C 2 ′ that comes into contact with a 3 ′ slides relatively easily, and the rubber plug C ′ is distorted as shown by the broken line in the figure. base
It comes off from a3 ' and comes out, and finally it also comes off from the crimping part a3 , and the entire rubber plug C' is detached from the terminal crimping part a3 , and is used for purposes such as maintaining the waterproof function of the electrical contact part mentioned above. There are drawbacks that you won't get.

る。 Terminal A of the present invention is the conventional terminal shown in Figure 1.
Similar to A', there is an electrical contact part (not shown) in the front, a wire conductor clamping part 2 in the middle, and a rubber plug with a larger diameter and expanding outward than the wire conductor clamping part 2 in the rear. It has a terminal structure in which wire crimping parts 1 are arranged in series,
The present invention is characterized by the structure of the electric wire crimping section 1 with rubber plug. That is, the electric wire crimping part 1 with a rubber stopper of the terminal according to the present invention is arranged above the middle part of the curved base part 1b in a direction perpendicular to the terminal axis direction and approximately parallel to the curved surface of the base end part 1b. A bridged protrusion 3 is formed inside the electric wire crimping part 1 with a rubber stopper.

程度に係合される。 First, the conductor b 1, which is obtained by peeling the end portion of the electric wire B into which the rubber plug C is inserted, is crimped in the conductor crimping part 2.
Next, the insulation coating part b 2 of the electric wire B is crimped together with the small diameter part C 1 of the rubber plug C inserted on the outer periphery of the electric wire B in the wire crimping part 1 with rubber plug. Then, the opposing crimping pieces 1a are crimped and crimped at the small diameter portion C1 of the rubber stopper C, and engage with the rear part of the annular rib C4 at the tip of the rubber stopper, as well as the base part of the wire crimping part 1 with the rubber stopper. The protrusion 3 bridged above 1b partially compresses the small diameter part C1 of the rubber stopper, while the compression rate of the rubber stopper by the base part 1b in front of the protrusion 3 decreases and the annular rib C at the tip of the rubber stopper decreases. 4 is no longer compressed smoothly,
The protrusion 3 pressed against the small diameter part C1 of the rubber plug is an annular rib.
It is engaged with the rear part of C 4 to the same degree as the engagement in the caulking piece 1a.
従つて、従来外力の付加によりゴム栓付電線加
締部1において生じ易かつたゴム栓の後方抜けが
略完全に防止される。 Therefore, the rubber plug can be almost completely prevented from coming off backward, which conventionally tends to occur in the rubber plug-equipped wire crimping section 1 due to the application of an external force.

A terminal including a wire conductor clamping part in the middle part and a wire clamping part with a rubber plug whose diameter is larger than the wire conductor clamping part in the rear part, a small diameter part and a large diameter part, and the terminal has a small diameter part and a large diameter part. The distal end of the part is made up of a rubber stopper with an annular rib surrounding it, and the base of the wire crimping part with the rubber stopper is cut and raised by a slit in a direction perpendicular to the terminal axis direction, and is raised along the curved surface of the base. A bridged protrusion is provided inside, the protrusion is crimped and fixed by a wire crimping part so as to engage with the annular rib of the rubber plug, and the protrusion bites into the rubber plug in a curved shape. Because of its characteristics, it is possible to form a relatively large protrusion in the wire crimping part with a rubber plug by cutting and raising, and the sharp end formed by cutting and raising can be engaged with the annular rib of the rubber plug. The protrusion cut and raised by the slit can be cut into the outer circumference of the rubber stopper in response to the tightening pressure, so that it can be positioned and locked securely. The rubber plug is reliably fixed to the terminal in response to changes in the diameter of the rubber plug portion, and from this point of view as well, it is effective in preventing the rubber plug from coming off backwards.
