Structural features of explosion-proof socket plugs

Explosion-proof plugs and sockets, also known as spark plug sockets, high-current plugs and sockets are mostly used in the field of electrical connections between mobile power stations and cables and loads. Widely used in petroleum, chemical, defense, power and transportation and other fields. The plugs and sockets are made of aluminum alloy shells, and the surface of the contact pieces is silver plated and the wire ends are crimped. It has the characteristics of quick and easy plugging and unplugging, convenient connection, reliable electrical contact, good sealing and insulation, waterproof and dustproof, shock and shock resistance, and long service life. It complies with the GB 3936.8-2003 "Electrical Equipment for Explosive Gas Environments Part 8 "n" Electrical Equipment" standard. The products have been inspected by the state-specified explosion-proof electrical product quality supervision inspection and test center.

400-1000A non-spark type single-core plugs and sockets can be used for field exchange of mobile power stations and cables, cables and cables, cables and the connection between the load, suitable for high current cable power supply. Four single-core connectors indicate A, B, C, and N poles, respectively. The housing of the plug seat adopts aluminum alloy die-casting, the contact parts are silver-plated, and the wires are crimped. It has the features of quick insertion and removal, waterproof and dustproof, and reliable connection.

Conforms to national standard GB3836.8-2003 and European standard EN60079-15:2005 "Electrical equipment for explosive gas atmospheres Part 8: Electrical equipment of type 'n". Explosion-proof mark: ExnAIIT 4. Obtained European ATEX certificate, numbered : CE0470Nemko07ATEX3202.

The connection between the plug and the socket is a bayonet type quick connection. The contact element and the wire termination form are crimped, the contact element is supported by an elastic ring gear, and the front disassembles the structure after installation. The plug seat adopts ZL-102 die-casting aluminum alloy, the contact parts are silver-plated, reliable in contact, convenient in connection, good in sealing and insulation, and has the characteristics of waterproof, dustproof and shockproof.
