Description

Technical Field

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

[0002] Power cords are wires that transmit 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 higher voltage alternating current. Due to the higher voltage, these wires need to obtain safety certification according to unified standards before they can be officially produced. DC cords basically transmit lower voltage direct current, so the safety requirements are not as strict as AC cords. However, for safety reasons, countries still require unified safety certification.

[0003] When using an existing power cord, the input end is usually connected to a power source, and the output end is connected to an electronic device. However, when the output end is connected to the electronic device, it is often bent and entangled, which makes it easy for the connection between the power cord and its output end to be damaged or broken, thereby shortening the service life of the power cord. When the power cord is disconnected from its output end, it is easy to cause power outages and leakage accidents, posing a major safety hazard. Utility Model Content
