Description

Technical Field

[0001] The utility model relates to a straight plug connector. Background Art

[0002] Connectors are commonly used connectors in cable connection work. Different cables are electrically connected through two different connections. Connectors generally include a plug assembly and a socket assembly. The socket assembly can extend into the plug assembly to electrically connect the male terminal to the female terminal.

[0003] The socket shell, connecting terminal and sealing gasket of most energy storage connectors on the market are manufactured separately. When in use, the three are first assembled into a board-end socket, and then the assembled board-end socket is connected to the electrical equipment together. Installation errors are prone to occur during assembly between the socket shell, terminal and sealing gasket, which may cause the assembled board-end socket to be skewed. When the connector is in use, the cable and the terminal need to keep in contact at all times. After errors occur in the installation of the socket shell and the connecting terminal, the terminal may deflect or misalign during use, resulting in unstable connection. Utility Model Content
