ことによって係止される。An elastic hollow cylindrical waterproof sealing member made of rubber or synthetic resin is inserted into the end of the electric wire to be connected, and a terminal fitting part (31) is inserted into the end.
The terminal 3 that has been prepared can be attached. The connection between the terminal 3 and the electric wire 1 is made by inserting an exposed conductor portion at the end of the electric wire 1 into the ``r'' section of the wire holding portion having a roughly U-shaped cross section that extends from the above-mentioned terminal joint portion 31. The terminal 3 is fixed to the end of the electric wire 1 by crimping both U-shaped plates so as to hold the standing tree part.
are arranged in parallel inside the hollow housing body 2 at a predetermined interval, and in order to prevent them from falling off from the housing body 2, rear,
The rear holder 5 to which the holder 5 is attached has a substantially U-shape, and has a pair of notches 51 for inserting electric wires, as shown in FIG. It is locked by engaging with a rear projection 22 formed protrudingly on the main body 2.

どの欠点がある。The female terminal 13 that is not to be connected and mated to the terminal 3 is fixed to the end of the other wire L in the same manner as described in F, and is housed and fixed in the female terminal housing C (not shown). As shown in FIG. 6, the terminal 3 and the female terminal 13 are fitted into each other so as to have a regular head C8. Reference numeral 6 indicates a sealing O-ring, which is used to seal the mating portion between the housing body 2 and the female terminal side housing.6 (Problems to be Solved by the Invention) However, in the conventional connector, , when the shape of the locking protrusion 21 protruding from the inner wall of the housing body 2 is improperly formed and it does not engage well with the stepped part of the terminal 3, or when the terminal 3 is housed in the housing body 2 during assembly work. If the terminal 3 is not engaged with the stepped part 32 from the beginning due to a mistake, when pushing the terminal 3 to connect it with the female terminal 13, the pushing force may cause the terminal 3 to be pushed inside the housing body 2. Retract in the axial direction, as shown in Figure 8! ! 27 The water seal member 4 is attached to the rear holder 5
Therefore, in this case, even if the male and female sides of the housing are firmly mated, the terminal 3
Naturally, a regular can length C6 cannot be obtained between the terminal and the female terminal 13, and an insufficient can length C6, which is shorter than Co, is created, resulting in heat generation due to insufficient contact area at the terminal connection part, and sometimes There are drawbacks such as the possibility of leading to serious accidents.

After inserting a waterproof sealing member into the end of the electric wire, the terminal of the connected electric material and the housing body that stores the pair of terminals in parallel with a predetermined interval are attached to the electric wire side end of the housing body. and a rear holder provided with a notch for inserting an electric wire, wherein the length of the waterproof sealing member is compressed in the vicinity of the notch for inserting an electric wire in the rear holder. In view of this, there is provided a wire harness connector characterized in that a protrusion that is set longer than the axial movable amount of the terminal is provided to protrude in the direction in which the terminal extends.

Even if the terminal becomes loose, the terminal is locked in its proper position within the housing body. Therefore, even when connecting with the female terminal, a proper and sufficient mating state can be obtained.
（実施例）
第１図ないし第３図についてこの発明の一実施例を説明
する。(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3.
第１図ないし第３図おいて、符号５３について以下に説

設けたことが特徴である。As already explained, the rear holder 5 is provided with a notch 51 for inserting the electric wire, but this is done by cutting out a circular hole on one side that matches the outer diameter of the electric wire 1, as shown in FIG. It has a U-shaped opening. In this invention, as clearly shown in FIGS. 3(a) and 3(b), the cutout portion 51 extends in the direction of the electric wire 1 along the circumferential portion of the cutout portion 51. The feature is that a protrusion 53 with a height e is provided.

ある。FIGS. 4 and 5 show another embodiment of the present invention, in which the carrier holder 5 is rotated to the wire insertion side end of the housing body 2 at a thinly molded hinge connecting portion 54. Even in the embodiment in which the rear holder 5 is freely connected, the side opposite to the rotating side is fixed to the housing body 2 by the locking window 52 engaging with the locking protrusion 22 of the housing body. A protrusion 53 is provided on the inner wall surface of the rear holder 5! Mr. r3 is similar to the previous example.
