No-spark three-phase four-pole anti-explosion plug

Abstract

Disclosed is a no-spark three-phase four-pole anti-explosion plug. The no-spark three-phase four-pole anti-explosion plug comprises a plug shell; a plug base is arranged on one side of the plug shell;a plug inner core is arranged in the plug base; an inner core lower cover and an inner core upper cover are arranged at the bottom of the plug inner core; the inner core lower cover is connected withthe inner core upper cover; a locking pin is arranged in the internal middle of the inner core upper cover; anti-explosion electrodes and grounding electrodes are arranged around the locking pin; auxiliary bolts are arranged on the peripheries of the anti-explosion electrodes and the grounding electrodes; a no-spark bolt is arranged at the bottom of each anti-explosion electrode; an E pole directional sheet is arranged on the outer side of the plug base; a tail frame is arranged at the other end of the plug shell; and a wire pressing plate is fixed on the tail frame.

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 plug. 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 hundreds ...

AI Technical Summary

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.
