Structure
The socket assembly should have sufficient elasticity to ensure sufficient contact pressure on the plug pins. The socket should be corrosion-resistant and wear-resistant to ensure good contact between the plug and the socket; the pin of the plug should be locked and cannot be rotated, otherwise it will affect the insertion performance and cause unsafe factors; the converter has a flexible cord fixing device to ensure The flexible cord is fixed and can withstand normal tension and torque; when the plug and socket are inserted, the mating surfaces should be basically tight to prevent electric shock accidents.
Power cable
The power cord of the conversion plug should have enough cross-sectional area to ensure that the power cord will not heat up and cause insulation damage, resulting in short circuit, fire, leakage, and accidents. Such as: the common 250V, 10A converter's power line cross-sectional area should be greater than or equal to 0.75mm2.
Mechanical strength
Plugs and sockets should have sufficient mechanical strength to withstand various mechanical stresses caused by drops, impacts, and extrusions during installation and use; sockets with protective doors should be able to prevent single-pole insertion.
Heat and flame resistant
High temperature has a great influence on various properties of insulating materials. Under high temperature conditions, the structure and characteristics of insulating materials will undergo essential changes. This change determines the reliability of the use of materials. Some materials will gradually soften at high temperatures. The mechanical strength is reduced, which will affect the quality of the plug and socket and the safety in use. In addition, the insulating material of the plug and socket should have certain flame retardant properties. Otherwise, if the product catches fire during use, it will be out of control.
