Technical Field
[0001] The present application relates to the technical field of sockets, and in particular to a charging socket and a vehicle. Background Art
[0002] With the development of the automobile industry, new energy vehicles have developed rapidly and their market share has gradually increased. Compared with traditional fuel vehicles that use the refueling port to add fuel to provide energy for the entire vehicle, new energy vehicles use the charging socket to connect to the charging pile to complete power transmission, thereby replenishing energy for the vehicle. New energy vehicle charging sockets are generally divided into two types: DC charging sockets and AC charging sockets.
[0003] There are multiple power terminals in the charging socket: the AC charging socket has N, L, PE, CC, CP power terminals, and the DC charging socket has DC+, DC-, PE, A+, A- power terminals. Each power terminal in the charging socket is generally composed of a crimping piece and a contact piece, wherein the crimping piece is connected to the wire, and the contact piece is connected to the plug terminal of the charging pile. Among them, the PE interface corresponding to the PE power terminal needs to be connected to the body of the whole vehicle, and the remaining interfaces need to be connected to the corresponding electrical components. In the past, the PE interface was connected to the body through the power terminal crimping wire. For example, the patent with announcement number CN215221187U provides a PE grounding solution, which uses a metal sheet to connect the PE power terminals of fast charging and slow charging together. That is to say, the fast charging port and the slow charging port share a wire and are connected to the body for grounding. Although one grounding wire is reduced, the wire harness manufacturer still needs to crimp the PE terminal, the grounding terminal and the wire together, and then assemble the grounding terminal connected to the body in the vehicle assembly workshop. The entire production process is relatively complicated and inefficient.
[0004] Therefore, the prior art needs to be improved. Utility Model Content
[0005] The purpose of this application is to provide a charging socket to solve the problem that the existing charging socket still requires the wiring harness manufacturer to crimp the PE terminal, the grounding terminal and the wire together, and then assemble the grounding terminal connected to the vehicle body in the vehicle assembly workshop, and the entire production process is relatively complicated and inefficient; the second purpose is to provide a vehicle.
[0006] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

[0008] According to the above technical means, by setting the terminal installation groove, the PE power terminal is assembled to the correct position. When the charging socket of the present application is applied, the charging socket manufacturer can directly connect the metal connecting piece, the charging socket body and the PE power terminal together without the need for wires when leaving the factory. That is to say, the wiring harness manufacturer does not need to do further processing. When assembling the charging socket, the vehicle assembly workshop uses the first threaded fastener to connect the double-threaded hole metal sleeve embedded in the charging socket body to the body sheet metal, and then the metal connecting piece on the double-threaded hole metal sleeve and the PE power terminal are connected to the body sheet metal, thereby achieving the purpose of grounding the PE power terminal. There is no need to additionally assemble and fix the grounding terminal of the traditional crimping solution, thereby improving the production efficiency of the wiring harness manufacturer and the vehicle assembly workshop.
