The utility model content

It is reliable that the purpose of this utility model provides a kind of connection, simple in structure, is applicable to the wire and cable connector in the higher environment for use of quality and space requirement.

For achieving the above object, the utility model adopts following technical scheme: a kind of wire and cable connector, comprise grommet, the cavity that connects before and after being provided with in the grommet, the middle part of described cavity is provided with conductive jacket along the cavity bearing of trend, and the two ends of conductive jacket all detachably fixedly are plugged with the contact plug that is connected with the conductive jacket conduction, and the end that described contact plug and conductive jacket are pegged graft is the inserting end, the other end is the terminals that are used for connection cable, and described terminals are positioned at cavity inside.

Described grommet internal cavity rear and front end is provided with the elasticity bulge loop near the inner surface of port, and the terminals of described each contact plug are positioned at the inboard of adjoining elasticity bulge loop.

Axial restraint is connected with the location conducting ring in the described conductive jacket, has the pawl of electrically contacting and support claw on the conducting ring of described location, describedly electrically contacts pawl and cooperates with the contact plug conduction, and described support claw pushes up with contact plug and only cooperates.

Described location conducting ring comprises the substrate of C shape, one side one of substrate is extended with and electrically contacts pawl and spacer, electrically contact between pawl and spacer the end and be provided with separation gap away from substrate, the inside punching out of described support claw one on spacer constitutes, the middle part of described contact plug is provided with the ring platform, described support claw cooperates towards the end face of support claw top with the ring platform with onlying, described electrically contact that pawl slopes inwardly away from the end of substrate and electrically contact with the outer peripheral face that encircles platform cooperate.

Described electrically contact pawl and spacer substrate circumferentially on alternately be provided with.

Have a through hole in the described conductive jacket, the inboard end near the rear and front end of through hole is respectively arranged with annular groove, and described location conducting ring is connected in the corresponding annular groove.

The terminals of described contact plug are provided with the line ball hole, line ball hole and the coaxial setting of contact plug.

Described grommet comprises the preceding grommet and the back grommet of coaxial fixedly grafting.

Wire and cable connector of the present utility model is simple in structure, compact, thereby is applicable to quality and space requirement than in the higher environment for use.With after contact plug is connected, contact plug is realized the reliability that two cables conduct to two cables to be connected in being inserted into conductive jacket respectively.

Near the elasticity bulge loop that is provided with on the inner surface of port, after connecting cable, play the effect of sealing in the cavity rear and front end, made this wire and cable connector have the ability of acidic fog resistance, humidity and anti-mould.The terminals of contact plug are positioned at the inboard of adjoining elasticity bulge loop, can satisfy the requirement of insulation so that after the cable connection, the conductor of cable and damper ends all is positioned at cavity.
