Technical Field

[0001] The utility model belongs to the technical field of power lines, in particular to an improved waterproof power line. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point-to-point. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that transmit alternating current with a higher voltage. Due to the high voltage, this type of wire requires unified standards and safety certification before it can be officially produced. DC lines basically transmit direct current with a lower voltage, so the safety requirements are not as strict as AC lines. However, for safety reasons, countries still require unified safety certification.

[0003] The power plug electrically connected at one end of the existing power cord is generally made of high-temperature and high-pressure one-piece molding and cannot be disassembled. When water enters the power plug, it is not convenient for people to disassemble the insulating top plate and the power socket for inspection and maintenance, which reduces the waterproofness and safety of the device.
