Abstract: A connector includes a housing (1), a plurality of electrical contacts (2) and a pair of grounding bridges (3). The housing has two opposite engaging arms (17) each having a post (174) formed thereon. A pair of mounting channels (162) is defined in two ends of the housing. First and second grooves (172, 171) are defined in an outside of the engaging arm. The grounding bridges each comprise a first leg portion (31) interferingly engaging into the channel, and a second leg portion (32) having a first flange (38) engaged with the first groove and a second flange (390) abutting against a front face of the engaging arm.
