Single-core metal connector

Abstract

The invention discloses a single-core metal connector, comprising a plug and a socket. The plug consists of a metal plug housing and a tubular power female terminal fixed inside the plug housing, Theinner part of the first end part of the power female terminal is coaxially fixed with a tubular elastic contact finger and a plug rod, the outer part of the power female terminal is provided with an insulating shell with both ends open and a cylindrical insulating sleeve matched with the insulating shell, and the second end part of the power female terminal is tightly matched with the insulating sleeve; the tail end of the plug rod is flush with the opening of the insulating housing; and the socket is composed of a metal socket housing and a tubular power male terminal fixedly arranged coaxially inside the socket housing, the power male terminal is internally provided with a socket matched with the plug rod, the socket housing and the plug housing are connected, and the power male terminaland the spring finger are tightly matched. The invention is made of all metal, and has better shielding performance, better electric conductivity, better internal sealing performance, less water permeability and higher safety.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a single-core metal connector. Background technique [0002] An electrical connector is a device for electrical connection and signal transmission between devices and devices, components and components, and systems. It consists of a fixed-end electrical connector (hereinafter referred to as "socket"), a free-end electrical as a "plug"). The socket is fixed on the electrical parts through its square (round) plate (some of them are also welded), the plug is generally connected to the cable, and the plug and socket are connected through the connecting nut, as shown in Chinese patent 201220711528.6. [0003] The plug is usually provided with contact fingers. In the prior art, the width of the contact fingers is generally relatively short, resulting in a relatively small contact area between the contact fingers and the male terminals in the socket, poor conduction effec...

AI Technical Summary

Problems solved by technology

In the improved structure, since the contact finger is hollow and long, its end is almost close to the surface of the plug, and the operator's finger is likely to touch the contact finger by mistake, which may lead to electric shock in severe cases

In addition, due to cost constraints, most of the existing electrical connectors are plastic shells, which are prone to deformation during use, have poor internal sealing, are prone to water seepage, have poor waterproof effects, and have low safety.
