Abstract
A modular jack (100) includes an insulative housing (1) having a plug-receiving cavity (10), a number of conductive terminals (322) and an anti-mismating member (2) received in the housing (1) and a metal shell (4) shielding the housing (1). The anti-mismating member (2) includes a metal main portion (21) having a horizontal spring arm (212) and an insulative portion (22). The insulative portion (22) is located at a free end of the spring arm (212) and includes a sliding surface (222) and a stop surface (221) attached to an inner side of the sliding surface (222) at a free end thereof. When an undersized plug is inserted into the cavity (10), the leading edge of the undersized plug contacts the stop surface (222), preventing full insertion of the undersized plug into the cavity (10). When a mating plug is inserted into the cavity (10), the leading edge of the mating plug contacts the more forwardly-positioned sliding surface (222) before reaching the stop surface (221). This movement produces a corresponding movement in the anti-mismating member (2) and the stop surface (221) thereon such that the stop surface is located out of engagement with the leading edge of the mating plug, p…
