Non-spark three-phase four-pole explosion-proof socket

Abstract

The invention discloses a non-spark three-phase four-pole explosion-proof socket which comprises a socket, a socket core and a socket cover. The socket core is arranged in the socket and is provided with a socket core lower cover and a socket core upper cover, the socket core lower cover is provided with a plug bush, and three-phase electrode tip plug bushes and auxiliary plug bushes are arrangedin the socket core upper cover; the socket cover is connected with the socket by a torsional spring and a socket cover shaft, and a socket cover sealing ring is arranged on the inner side of the socket cover and is positioned at a joint of the socket cover and the socket; a push handle device is arranged on the outer side of the socket cover.

Description

technical field [0001] The invention belongs to the field of electrical connection related equipment, in particular to a non-spark type three-phase four-pole explosion-proof socket. Background technique [0002] In construction sites, vast rural areas, and small and medium-sized enterprises with low degree of automation and imperfect power protection devices, three-phase power supply phase failures often occur, resulting in three-phase electrical appliances not working properly. Electricians need to use tools such as test pens or multimeters for maintenance. Phase-by-phase detection is not fast enough. The grounding failure of electrical equipment is a major safety hazard, which not only violates the "Ten Prohibitions on Safe Use of Electricity", but also endangers personal safety. [0003] In various electrical equipment, the amount of electrical connectors is increasing. Generally speaking, the amount of electrical connectors used on a piece of equipment can reach hundred...

Problems solved by technology

[0002] In construction sites, vast rural areas, and small and medium-sized enterprises with low degree of automation and imperfect power protection devices, three-phase power supply phase failures often occur, resulting in three-phase electrical appliances not working properly. Electricians need to use tools such as test pens or multimeters for maintenance. Phase by phase detection, not fast enough

The grounding failure of electrical equipment is a major safety hazard, which not only violates the "Ten Prohibitions on Safe Use of Electricity", but also endangers personal safety.

[0003] In various electrical equipment, the amount of electrical connectors is increasing. Generally speaking, the amount of electrical connectors used on a piece of equipment can reach hundreds to thousands of pieces, involving tens of thousands of lines. Electrical connectors The electrical connection and signal transmission between devices and devices, components and components, and systems are the basic components necessary to form a complete system. However, the existing electrical connectors cannot be used for explosive gas environment electrical equipment

At the same time, most plugs and sockets have poor waterproof and sealing performance, and improper use will cause accidents and cause huge economic losses.
