Power plugs can generally be divided into 2-core power plugs, 3-core power plugs, and multi-core power plugs
2-core power plug:
2-core power plug, as the name suggests, means that the plug has two inserts or two pins. The specific insert or pin is different in each country's standard, such as two inserts in China and two round pins in Europe
3-core power plug:
A 3-core power plug, as the name suggests, means that the plug has three inserts or three pins, or two inserts or two pins plus a grounding hole. This structure is more complex than a 2-core power plug, and there are significant requirements for the size and diameter of the pins. The length and distance between the pins are factors to consider Multi core power plug: This multi core power plug is even more complex. According to the customer's requirements, the use of 4-core power plugs or 5-core power plugs on any specific device should be considered based on the actual situation
Inspection standard for socket plugs: GB2099.1-2008 "Plugs and Sockets for Household and Similar Purposes - Part 1: General Requirements". GB1002-2008 "Types, Basic Parameters and Dimensions of Single-phase Plugs and Sockets for Household and Similar Purposes"
Inspection items: Inspection of marking dimensions: Resistance to aging, protection and moisture-proof insulation resistance provided by the shell, and electrical strength. The force required for pulling out the plug and its connection with heat-resistant insulation materials is resistant to abnormal heat, combustion, and electric tracing.
