Novel D-sub interface socket structure

The utility model discloses a novel D-sub interface socket structure. The novel D-sub interface socket structure comprises a socket equipped with a D-sub interface. The socket comprises a socket body, a plurality of signal terminals and a weld leg for fixation. The plurality of signal terminals are arranged in the socket body. Welding pins are arranged on the plurality of signal terminals. The welding pins extend to the exterior of the socket body. One end of the weld leg for fixation is connected with the body. The other end of the weld leg for fixation extends to the exterior of the socket body. The welding pins and the other end of the weld leg for fixation are arranged on one surface of the socket body. The welding pins and the weld leg for fixation are distributed at two ends of one surface of the socket body respectively. The socket structure solves the problem that after a traditional D-sub interface socket is welded on a circuit board, the traditional D-sub interface socket is easy to loosen and warp, and the firmness of the interface terminal and the stability of signal transmission are raised.
