Abstract

The connector includes an insulative housing, two rows of contacts retained in the housing, and a metallic shell enclosing the housing. The contact includes a contacting section extending into the mating cavity, and a connecting section exposed outside of the housing. An insulative block/spacer is attached to a back side of the housing integrally with a metallic shielding/grounding blade therein. The shielding/grounding blade includes a pair of securing legs at two ends in the transverse direction. A pair of grounding bars are soldered to the outer conductors of the two rows of wires, respectively. Each of the grounding bars includes a pair of securing legs at two ends in the transverse direction. Both the securing legs of the shielding/grounding blade and those of the grounding bars are secured to interior surfaces of the two side walls of the outer shell.
