Description

RLEATED APPLICATION The present disclosure claims the priority of the Chinese patent submitted on August 06, 2021, with the application number 202110903678.0 and the patent title "charging socket and vehicle". TECHNICAL FIELD The present disclosure relates to the field of connection of electrical connection elements, particularly to a charging socket and an vehicle. BACKGROUND With the gradual popularity of electric vehicles, market demands for charging plugs and charging sockets are gradually increasing. In prior arts, a charging socket in a charging system includes a charging terminal and a cable, the charging terminal and the cable are connected inside the charging socket, the charging terminal is fixed on a charging socket body, and the cable is connected with the charging terminal. Due to excessive times of insertion and removal, or due to a short circuit, some charging terminals in the charging socket will be damaged. When repairing and replacing a charging terminal, all the cables of the charging socket need to be removed from a vehicle body first, then a rear cover of the charging socket is detached, the charging terminal connected to the cable is taken out. A charge terminal, plug bush that charges, a fill electric gun and a charging seat are known from the prior art, for example from CN206992349U. A ladeverbinder is known from the prior art, for example from DE112014004814T5. A replaceable terminal, a charging socket and an electric automobile are known from the prior art, for example from CN209298410U.A welding mode is generally adopted for the charging terminal and the cable, thus it needs to cut off a damaged electric connection device; since there is no repair allowance for setting a cable length, the cable may need to be replaced, outer sheath and tapes of the entire cable need to be removed, then the charging socket can be repaired, the whole process needs to consume a lot of manpower and time, which seriously affects the efficiency of after-sales repair, hence in the prior arts, a new solution is urgently needed to solve said problem. CN113173087A discloses a charging socket comprising: a charging socket body, a charging terminal, a shield member and a cable , wherein the shield member comprises a detachable structure and a fixed end which are connected in sequence, the fixed end is electrically connected with a conductor of the cable, the shield member is fixedly mounted on the charging socket body, a connection structure is provided on the charging terminal, and the charging terminal is detachably connected with the detachable structure via the connection structure, a front end of the charging socket body is provided with a cavity within which the detachable structure is provided, the charging terminal is inserted into the cavity via an opening of the cavity and is detachably connected with the detachable structure via the connection structure, wherein a rear end of the charging terminal is provided with a disassembly portion, and a cross-section shape of the disassembly portion is a flat shape.
