CN210040659U shows an automotive charging gun that comprises a gun head equipped with multiple openings. One end of the contact is inserted into an appropriate socket, through a contact-mounting opening, and the other end is connected to the wires of the electrical connector. The first contact-mounting portion is positioned on the side wall of the mounting opening of the pins of the contact housing and the second one is positioned on the outer surface of the contacts, the second mounting portion being mated with the first mounting portion to restrict axial movement of the contacts within the contact housing. The pin of the charging gun is rigidly fixed and not easy to loosen, the charging stability is better and the service life is extended. The contacts according to this invention have one recess (no. 23, closer to the free end of the contacts) and two protrusions (no. 22) in the form of peripheral projections. The tightness of the joint is achieved with a seal (no. 6) in the recess 23, and the protrusions 22 and a gap (no. 21) between them ensure the fixing of the contacts by an element (no. 32) - which gives the following sequence of elements starting from the free end of the contacts: first, theseal 6 around the contacts, then, mounting elements 21, 22. The purpose of this design is to prevent water and dust from entering the connector at the front of the plug. - Another Chinese utility model
CN210379629U discloses an electrical connector for cars in which contacts have at least two narrowings used to immobilise them. In contrast, neither of the narrowings is provided with sealing means. The watertight properties of the electrical connector are achieved by using a seal on the outside of the entire connector. - Chinese utility model
