## Abstract

The present application provides a charging socket including a socket body, the socket body is provided with a charging end configured to connect to a charging plug, a conversion end configured to connect to a battery pack, and a terminal accommodating cavity communicated with and between the charging end and the conversion end; the conversion end is provided with a mating installation groove configured to mount an adapter plug and configured to pluggably connect with the adapter plug. In the charging socket provided in the present application, only the adapter plug is required to be pulled out from the mating installation groove on the socket body when the charging terminal mounted in the terminal accommodating cavity needs to be repaired or replaced, thereby removal of the connection between the charging terminal and the battery pack is completed, which effectively reduces the difficulty of disassembly and assembly. Therefore, this process is simple, improves the working efficiency, and reduces the maintenance cost.
