[0011] The difference between the insertion portion M and conventional insertion portion M 0 of the present embodiment is only relevant portions of the cylindrical portion 1a of the shell 1 in the insertion portion M. That is, in the present embodiment, one O-ring 106a is externally fitted to the cylindrical portion 1a, whereas in the conventional example, two O-rings are externally fitted. In the inserted portion F, an O-ring groove 2d is formed at the point where the shell insertion portion formed on the peripheral wall portion 2 is configured in two stages and on the contact surface side of the peripheral wall portion 2 with the flange portion 101b. This is the point where the O-ring 3 is arranged. That is, on the side near the male terminal 112 inside the peripheral wall portion 2, the O
A first shell insertion portion 2a having an inner diameter closely contacting the outer diameter of the ring 106a is formed, and a second shell insertion portion 2b having a diameter larger than the outer diameter of the O-ring 106a is formed continuously with the first shell insertion portion 2a. Have been. The depth of the first shell insertion part 2a is smaller than the depth of the second shell insertion part 2b.

When the insertion portion M thus configured is inserted into the insertion portion F, most of the air inside the shell insertion portion escapes from the gap G to the outside as shown in FIG. Go. When further inserted, the O-ring 106a is brought into close contact with the first shell insertion portion 2a and compresses the air in the first shell insertion portion 2a. However, since the air is very small, the internal pressure is not increased. , Core wire 10
No force is applied to 3a or the like, and no separation occurs between these members. When further inserted, O-ring 3 and flange 1
01b is contacted, and the tightness of the cap nut N ensures watertightness of this contact portion. Therefore, the intrusion of external moisture into the internal male terminal and female terminal is prevented, and since there is no separation between the members as in the conventional example, stagnation of moisture is prevented and electrical insulation is secured. be able to.
