Description

Technical Field

[0001] The utility model relates to the technical field of high-current sockets, in particular to a high-current DC socket with a protection function. Background Art

[0002] The existing socket matching the DC power supply is composed of a horizontal socket, a vertical socket, an insulating base, a fork-shaped contact spring, and a directional key slot. Two fork-shaped contact springs are positioned at the center of the base, arranged vertically and horizontally and not connected to each other. One end of the fork-shaped contact spring is a wiring port, exposed on the top surface of the base cylinder, for connecting the input power cord or cable. The other end of the fork-shaped contact spring is composed of two elastic arms interconnected by the base, which are arranged in the insulating base socket in the direction of DC plug insertion to enable it to work normally.

[0003] Traditional DC sockets use a positive copper column and a riveted terminal structure. This structure makes it easy for the plug to cause poor contact if it vibrates for a long time after being inserted into the DC socket, which can easily cause the socket temperature to rise and affect the service life of the product; if used in a dusty environment, it may also cause an explosion, causing damage to personal injury and property.
