Problems solved by technology

In some flammable and explosive special occasions, such as coal mines, chemical plants and oil and gas stations, the sparks generated by the hot plugging of connectors will cause combustibles to burn and explode, causing casualties or property losses
In addition, the plug-in and pull-out structure between the socket and the plug of the existing connector, after a long period of use in a vibrating environment, the socket and the plug will be falsely connected due to vibration, or even disconnected, affecting normal work

Embodiment Construction

[0023] Such as figure 1 and figure 2 As shown, in a preferred embodiment of the explosion-proof connector of the present invention, the explosion-proof connector includes a receptacle 100 and a plug 200 mated with the receptacle 100 . Described socket 100 comprises socket base 5 and detachable tail cap 2, offers a through hole 22 on the socket base 5, is provided with internal thread in the through hole 22, and a step 51 is arranged in the middle of through hole 22, and through hole 22 Divided into two sections. Wherein, the first section is used for connecting the tail cap 2 , and the second section is used for connecting the plug 200 .

[0024] The tail cover 2 is provided with a boss, and the outer wall of the boss is provided with an external thread, which is adapted and screwed with the internal thread of the first section of the through hole 22 . The edge of the tail cover 2 is provided with a plurality of arc-shaped gaps. After the tail cover 2 is screwed to the thr...

Abstract

The invention relates to an explosion-proof connector, which comprises a socket and a plug adaptive to be inserted in the socket, wherein the socket comprises a socket base; conductive pins playing arole of conduction are arranged on the socket base; and zero wire or earth wire pins in the conductive pins are higher than other pins. In the adaptive insertion of the socket and the plug, the zero wire or earth wire pins contact conductive jacks on the plug, and then are disconnected with the conductive jacks, thereby effectively avoiding the generation of electric sparks. The connector also hasthe advantages of simple use and low maintenance cost.

Description

technical field [0001] The present invention relates to a connector, more specifically, to an explosion-proof connector. Background technique [0002] In the prior art, the connector includes a socket and a plug, and a plug connection is adopted between the socket and the plug. This plug connection structure will generate electric sparks during hot plugging. In some flammable and explosive special occasions, such as coal mines, chemical plants and oil and gas stations, the sparks generated by the hot plugging of connectors will cause combustibles to burn and explode, causing casualties or property losses. In addition, the plug-in and pull-out structure between the socket and the plug of the existing connector, after being used in a vibrating environment for a long time, the socket and the plug will be falsely connected or even disconnected due to vibration, affecting normal operation. Contents of the invention [0003] The technical problem to be solved by the present inv...
