A flange 5a to be inserted into is inserted into the large-diameter insertion hole 6a and held by the projection 9 of the rear insulator 3b on the other hand.

A concave insertion groove 11 for fitting an O-ring 10 is provided on the inner surface of the front end side of the receptacle shell 1, and an O-ring 12 is fitted on a surface of the flange 1d provided on the outer periphery of the intermediate portion corresponding to the nut 2. A groove 13 is provided so as to maintain airtightness during connection and tightening.

FIG. 3 shows another embodiment of the receptacle. Reference numeral 21 is a receiving stepped portion 21a of the internal front insulator 23a and a groove 21b for fitting a set spring 24 provided at one end thereof. A receptacle shell main body provided with a mounting flange 21d. Inside the main body 21, an insulator 23 composed of a pair of a front insulator 23a and a rear insulator 23b is provided, and the front insulator 23a side is located at the stepped portion 21a side. It is fitted together with the insulator 23b and held by the set spring 24 fitted in the step portion 21a and the groove 21b.

The front insulator 23a is made of synthetic rubber such as ethylene propyne rubber, and has a large diameter insertion hole 26a into which a flange 25a provided on a female contact 25 described later is inserted and a small diameter portion at one end thereof. A plurality of insertion holes 26b to be inserted are arranged in accordance with the number of contacts, and a protruding holding portion 27 is provided on the front side to prevent the contact 25 from collapsing and to prevent the contact 25 from falling off. .

[Effect of the invention]

 According to the present invention, when airtightness is required and the insulator is only a rubber material, for example, the contact collapses to the left or right when a force is applied, but since the insulator is a pair of insulators made of hard resin and synthetic rubber, the hard resin acts. As a result, the contacts do not fall down and there is no falling down, which facilitates fitting at the time of connection. In addition, the synthetic rubber keeps the airtightness and prevents it from falling off.

Further, when only a hard insulator such as a hard resin is used, it is necessary to perform a potting process between the contact and the inner circumference of the receptacle shell with silicon or the like, but a synthetic rubber and a hard resin are used. By doing so, there is an effect that it is not necessary.
