Description

Plug-in terminal structure with auxiliary functions

Technical Field

The utility model relates to a plug-in terminal structure with auxiliary functions, belonging to the technical field of wiring terminals.

Background Art

The plug-in series terminal blocks are used to achieve electrical connections. They are used for wiring like terminal blocks, and there is no strict difference. It’s just that terminal blocks are usually used in distribution boxes for convenient wiring, and the power they withstand is generally small. The plug-in series terminal blocks are made up of two parts for plug-in connection. One part presses the wire tightly and then plugs it into the other part, which is soldered to the PCB board. This connection is based on the mechanical principle of the bottom. This anti-vibration design ensures the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added at both ends of the socket. The assembly ears can protect the tabs to a large extent and prevent the tabs from being arranged in a poor position. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have assembly buckles and locking buckles. The assembly buckles can be more firmly fixed to the PCB board, and the locking buckles can lock the mother body and the socket after installation. Various socket designs can be matched with different mother body insertion methods.

In the existing plug-in terminal structure, when connecting the wire, the wire is inserted into the wiring hole, and then the locking screw on the side of the terminal is rotated to fix the wire. Such a structural design requires a special screwdriver to lock the screw, which is inconvenient. At the same time, in order to fix the socket, screws are also provided on the side of the socket. The screws are locked, and the screws need to be continuously rotated by tools for installation. Such a structural setting greatly affects the installation efficiency of the terminal, and a corresponding auxiliary structure needs to be provided for auxiliary installation.
