the terminal rear end is the welding part, and the front end is pinhole portion, pinhole portion upper end is equipped with spacing portion, the terminal still is equipped with the cardboard, the cardboard can block in the draw-in groove.

The socket is provided with a limiting groove, and the side surface of the socket is provided with a limiting groove B.

Further, the limiting plate can be inserted into a limiting groove, the limiting block can be inserted into a limiting groove B, the limiting plate and the limiting groove are in interference fit, and the limiting block and the limiting groove B are in interference fit.

Furthermore, a plurality of metal pins are arranged in the socket, and the positions of the metal pins correspond to the terminal holes in the plug.

Further, the needle hole part and the limiting part form a shape similar to a Chinese character 'tu', the diameter of the limiting part is smaller than that of the metal needle, and the metal needle is in interference fit with the needle hole part.

Further, the clamping plate is an elastic metal sheet.

The utility model has the beneficial effects that: through separating mouse connecting wire and terminal, independently imbed the plug shell with the terminal, avoided the soft shortcoming that is difficult to the installation of connecting wire, the installation is more swift.

Through reserving the welding part at the terminal tail end, the mouse connecting wire can be welded on the welding part, and need not to insert the plug shell, connects more firmly, and is more convenient.

By arranging the clamping grooves in the shell and the clamping plates of the terminals, when the terminals are placed in the shell, the clamping plates and the clamping grooves are clamped, and positioning and installation can be completed;

the limiting plate and the limiting block are arranged on the plug shell, the limiting groove and the limiting groove B are arranged on the socket, and the limiting plate and the limiting block are respectively inserted into the limiting groove and the limiting groove B when the plug is inserted into the socket, so that the plug is prevented from being loosened after being inserted into the socket.
