A short-circuit protection connector with electromagnetic shielding function

Abstract

The invention discloses a short-circuit protection connector with the electromagnetic shielding function. The short-circuit protection connector with the electromagnetic shielding function comprises a socket and a plug connected with the socket. The socket comprises an outer shell, a short-circuit movable module and a jack assembly, wherein the short-circuit movable module and the jack assembly are arranged in the outer shell. The short-circuit movable module is composed of an inserting needle, a shielding cover, a copper plate and an inserting needle base. The inserting needle is installed in the inserting needle base after being fixed through soldering tin and the copper plate and the inserting needle base is fixed to the shielding cover; the jack assembly is composed of jacks, an upper jack base and a lower jack base, wherein the jacks are formed in the upper jack base and the lower jack base and is completely fixed to the outer shell through an outer shell inner step and a fixing nut and a spring is arranged between the short-circuit movable module and the jack assembly. According to the short-circuit protection connector with the electromagnetic shielding function, mutual switching of a short circuit and an open circuit between contacts can be achieved, the electromagnetic shielding and sealing effects are good, and therefore the short-circuit protection connector with the electromagnetic shielding function can be widely popularized and applied to the technical field of electric connectors.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, in particular to a short-circuit protection connector with electromagnetic shielding function. Background technique [0002] In terms of electrical system testing and application, it is often necessary to realize short-circuit and open-circuit switching between electrical circuits for the purpose of testing, application convenience, and safety protection. In particular, it is necessary to set short-circuit and open-circuit functions on the connector. [0003] In order to meet the above functions of the connector, at present, the wires are usually welded directly to the wires with contacts at the end of the ordinary electrical connector, and the short circuit is realized between the positioned holes through the wire connection. When the open circuit function is required, Cut the connector wire directly to open the circuit. Although this method can realize short-circuit and open-circ...

AI Technical Summary

Problems solved by technology

Although this method can realize short-circuit and open-circuit switching between electrical circuits, it has no mobility, and it is inconvenient to realize short-circuit and open-circuit switching between contacts.

In order to realize the short-circuit and open-circuit switching between the contacts, various short-circuit electrical connectors have appeared at present. These electrical connectors are usually provided with a short-circuit module in the socket to realize the short-circuit and open-circuit switching between the contacts. The connector does not have electromagnetic shielding function, and the sealing performance is poor, it is difficult to meet the use requirements of electrical connectors
