Modular universal connection port

A universal electrical connector station includes an upper shell (1), a lower shell (3) and a circuit board (2) with several connectors (21) mounted thereon. Each shell (1, 3) has a body (11, 31) and several side walls (12, 13, 32, 33, 34, 35) extending from edges of the body (11,31). A number of openings (36) are defined in predetermined positions of the side walls (32, 34) for receiving connectors (21) therein. The shells (1,3) form several ribs (17, 39) on inner side walls of the shells (1, 3) for supporting the circuit board (2) at a predetermined position after the upper and lower shells (1, 3) are assembled together. A pair of upper and lower locking structures (14, 38) is provided on opposite side walls (13, 14, 33, 35) of the upper and lower shells (1, 3) in a same direction, respectively, for assembling the upper and the lower shells (1, 3) together.
