How To Install A DC Power Outlet

The socket assembly of the DC power socket should have sufficient elasticity to ensure sufficient contact pressure on the plug pin. 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;

Poor quality of DC power sockets and converters is an important cause of electrical fires. The quality problems of small plugs, sockets and converters will cause serious harm to the personal and property safety of consumers. Therefore, consumers should focus on the safety of products when purchasing plugs, sockets, converters and switches, and the main factors affecting their safety are the following performance indicators:

First of all, the sign is an important basis for instructing people to install, use and maintain correctly, and it is an extremely important safety standard content to ensure the safety of personal and property. Plug and socket products should be marked with rated current, rated voltage, power supply properties, etc. in obvious positions. In addition, converters (converters refer to mobile electrical accessories with only one plug part and one or more socket parts combined) products should be marked with the "MAX (or maximum)" symbol to indicate the rated current/or power, To guide users to avoid overloading. Signs or symbols should be durable and legible. The silk screen and paper stickers that can be easily erased should not be used; the rated value is the most basic electrical interchange matching parameter to ensure the normal, safe and cooperative use of the plug, socket, converter and the connected electrical appliance. For example: the rated current of the converter shall not be greater than the rated value of the plug part. Otherwise, it may cause danger when the user selects electrical appliances according to the rated current of the socket, and the plug overcurrent heats up, causing danger; the minimum rating of the converter with fuse and overload protector should be equal to the mark on the fuse and overload protector. rated value. Otherwise, product damage may occur.

Size is an important technical requirement related to whether DC power sockets and converters can be used safely and meet general interchangeability requirements to avoid misinsertion. The unqualified size will affect the user's use or cause hidden dangers such as poor contact and misinsertion, which will damage the equipment at light level, and cause fire and electric shock accidents in severe cases; A key safety indicator that will not cause electric shock accidents to users and others in the event of an accident. When the plug is fully or partially inserted into the socket, the live parts of the plug shall not be accessible; any plug of the plug shall not be able to be inserted into the live socket of the socket when the other plugs are accessible. Plugs, sockets and converters with protective doors should be able to prevent single-pole or probe insertion.

Finally, the socket components of the DC power socket 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.
