The first contacts are disposed in the insulative housing. The contact module is received in the second receiving cavity and has an insulative base (31), a number of second contacts (32) and a shielding plate (33). The metallic shell is attached to the mating face of the insulative housing and having a plate section (41) defining a central opening (410) in alignment with the first receiving cavity, and a pair of opposite ends (42) extending from the plate section and inserted in the insulative housing. The metallic shell has electrical connection with the shielding plate of the contact module.
