Abstract: A cable connector comprises a main body, a shielding shell surrounding the main body, and a cover unit covering the shielding shell. The shielding shell includes a top shell and a bottom shell attached together. The top and bottom shells form a number of seating holes. The cover unit includes a top portion and a bottom portion attached together. The top portion forms a first and a second side walls. The first side wall of the top portion forms a cutout and a protrusion. The bottom portion has a first and a second side walls on opposite sides. The first side wall of the bottom portion forms an upwardly extending flange for insertion into the cutout of the first side wall of the top portion, and an upwardly extending latching tab defining an opening for engaging the protrusion of the top portion. The top and bottom portions form a number of seating columns for insertion into corresponding seating holes.

Abstract: A locking device for an electrical connector comprises an engaging rod defining an outer screw thread thereon for engaging with a bolt of a mating connector defining an inner screw thread therein, and an additional inserting rod inserted into the engaging rod. The engaging rod comprises a through hole and a pair of gradually narrowed slots disposed around an end thereof in communication with the through hole. The inserting rod is inserted into the through hole of the engaging rod to expand the slots whereby the outer screw thread of the engaging rod latchably engages the inner screw thread defined in a screw hole of the bolt thereby securing the electrical connector and the mating connector together.
