Description

Wire and cable connector

Technical field

The present invention relates to a kind of wire and cable connector, belong to technical field of electric connectors.

Background technology

When two cables are connected, the general at present dual mode that adopts, a kind of mode is to adopt wire and cable connector to connect, another kind of mode is directly to adopt manual the connection.The general structure more complicated of existing wire and cable connector, and physical dimension is bigger is not suitable for using in the environment for use higher to quality and space requirement.The manual connection generally is to adopt hinge joint and two kinds of forms of spooling; Adopt the form of above-mentioned two kinds of manual wiring; Its wiring quality and operator's technical merit and operating state have closely gets in touch, thereby is difficult to guarantee that cable junction, every place can both reach good connection status.

Summary of the invention

It is reliable to the purpose of this invention is to provide 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 realizing above-mentioned purpose, the present invention adopts following technical scheme: a kind of wire and cable connector comprises grommet; The cavity that connects before and after being provided with in the grommet; The middle part of said 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 said 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 said terminals are positioned at cavity inside.

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

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

Said 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 the spacer end away from substrate and be provided with separation gap, the inside punching out of said support claw one on spacer constitutes, and the middle part of said contact plug is provided with the ring platform; Said support claw cooperates towards the end face of support claw top with the ring platform with onlying, said electrically contact that pawl slopes inwardly away from the end of substrate and electrically contact with the outer peripheral face that encircles platform cooperate.

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

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

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

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

Wire and cable connector of the present invention 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.

The elasticity bulge loop that on the inner surface of cavity rear and front end near port, is provided with has played the effect of sealing after connecting cable, make 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.
