Rotary contact socket and plug

Abstract

The invention relates to rotary contact socket and plug. A three-pole jack slide and a two-pole jack slide are arranged on a socket front housing, each jack slide comprises a jack and a narrow slide which are communicated, a horizontal electrode clamping spring is fixed in the front shell, and a rear cover is fixed on the front shell to form a housing. A three-pole cascade insert, a three-pole power lead jacket and a three-pole power lead are fixed on a three-pole plug; and a two-pole cascade insert, a two-pole power lead jacket and a two-pole power lead are fixed on the plug II. According to the rotary contact socket and plug, under the condition of reaching the rated load of the traditional socket and plug, the ultrathin structure is realized; after the pug is inserted into the socket, the plug is locked with the socket, the plug can not be vertically pulled out, no shaking exists between the socket and the plug, so that the socket and the plug can keep better contact for a long time; and the rotary contact socket and plug are safe in use and convenient for operation.

Description

technical field [0001] The invention relates to a power socket plug, in particular to a rotary contact type socket plug. Background technique [0002] The power socket plug is divided into two types: fixed type and mobile type according to the purpose, and is divided into a universal jack and a dual-purpose jack according to the form of the plug and the jack of the socket. At present, the thickness of the socket plug is relatively large, especially the mobile socket is more prominent. When the plug with vertical power lead is inserted into the socket, the height of the occupied space can reach about 8 cm. After the plug with horizontal power lead is inserted into the socket, its height It can also reach about 6 cm. After some sockets have been used for a period of time, the clamping degree of the electrode clamp spring to the plug electrode insert is not enough, and some universal jacks and dual-purpose jacks will also reduce the contact surface with the plug electrodes due...

AI Technical Summary

Problems solved by technology

After some sockets have been used for a period of time, the clamping degree of the electrode clamp spring to the plug electrode insert is not enough, and some universal jacks and dual-purpose jacks will also reduce the contact surface with the plug electrodes due to the consideration of different types of plugs. It may lead to poor contact between the socket and the plug, increase the contact resistance, cause the contact part of the socket plug electrode to heat up or generate arcing

After the plug is inserted into the socket, because there is no locking device, when it is subjected to vibration or external force, it will cause loosening or even separation between the socket and the plug, which will cause inconvenience to use.
