Technical Field

[0002] There are two types of quick-change charging sockets on the market: the first type is that only part of the terminals can be replaced; for example, only DC+ or DC- or DC+ and a terminal or DC- and a terminal are replaced, and the remaining terminals cannot be removed, so all terminals cannot be removed at will; when a non-removable terminal needs to be uninstalled or when a non-removable terminal is damaged, it can only be solved by removing the entire charging socket and related wiring harnesses, which not only increases the difficulty of construction, but also increases the cost of manufacturing and maintenance. The second type is that all terminals are replaceable; however, the disassembly and assembly process is relatively cumbersome, and the entire shell needs to be disassembled for disassembly, and the installation needs to be aligned with the hole and pushed in forcefully, which is time-consuming and laborious. For example, the existing patent application number is CN108987996, and the patent name is a replaceable charging socket, which discloses that the socket head and the socket tail can be detachably covered and connected, and the end of the socket head away from the socket tail is provided with a front cover covering the socket head, the front cover is hinged to the socket head, and the end of the socket tail connected to the socket head is provided with a charging terminal jack and a ground terminal jack; therefore, it is necessary to remove the socket head connected with the front cover and expose the terminal jack before the disassembly and assembly of the charging socket can be completed, and it is necessary to plug the terminal jack into the T-shaped hole at the socket tail, and the hole is deep, so it is necessary to push it in forcefully when inserting to complete the plugging of each terminal jack and the ground terminal jack, so its installation and disassembly are relatively cumbersome, the maintenance time is increased, and the charging socket cannot be quickly replaced.
