Abstract

The utility model provides a connecting terminal used for a socket. The connecting terminal includes a connecting case with a cavity inside and screws. On the top of the cavity, the connecting case is provided with screw holes which match with the screws. The connecting terminal also includes contact sheets. The two sides of the connecting case are provided with a wire inlet and a wire outlet respectively. One end of the contact sheet is arranged on the upper part of the connecting case and is provided with a welding part which matches with a wire, and the other end extends to the bottom of the cavity via the wire outlet. The connecting terminal of the utility model carries out the connection in a screw fastening mode at the wire inlet, and carries out the welding in a tin soldering mode at the wire outlet, thus avoiding the repeated connection by a user. The entire structure of the connecting terminal become more concise, and the amount of the material needed is reduced. Besides, the contact sheet which is used to switch on the power supply can be made of copper, and a terminal frame can be made of iron, thus saving the material and reducing the cost. Because the connecting case is also provided with anti-fallout buckles, the screws are not easy to fall out from the anti-fallout buckles, thus preventing the loosening and lost of the screws.
