The utility model relates to a computer fitting, particularly a connector which is characterized in that a hanging groove is arranged on a D-SUB joint, and tinplate is composed of left tinplate and right tinplate. The upper end of the tinplate is provided with a hook, the middle part of the tinplate is provided with a retreat stopping hook, the lower part of the tinplate is provided with a fastening groove, the hook of the tinplate is mutually connected with the hanging groove on the D-SUB joint, and the fastening groove of the lower part of the tinplate is clamped on a cable. A retreat stopping groove is arranged in an injection molding shell, and the retreat stopping groove on the injection molding shell is mutually connected with the retreat stopping hook on the tinplate. The original production technology is changed by the utility model, PVC is firstly injected and molded to make the injection molding shell, and then the cable passes through the injection molding shell, a conducting wire in the cable is mutually connected with a connecting column of the D-SUB joint, and the tinplate is assembled well and inserted into the injection molding shell. So, once injection molding is reduced, materials are saved, operation procedure and operation difficulty are reduced, and the utility model is easy to ensure the quality of a product.
