  • Patent number: 6935900
    Abstract: A modular jack (100) includes an insulative housing (2) with a plug-receiving cavity (24), an anti-mismating member (3) and a terminal module (4) received in the housing, and a metal shell (6) shielding the housing. The anti-mismating member (3) is formed by one metal sheet and includes a pair of cantilevered branch portions (32) extending forwardly into the plug-receiving cavity. Each branch portion includes a stopping tab (33) projecting upright from an inner side thereof and a guiding portion (34) extending upwardly from an outer side thereof. Each stopping tab has an engaging surface (331) facing forwardly. Each guiding portion has an inclined guiding surface (341) in front of the engaging surface.

  • Patent number: 6918794
    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).

  • Patent number: 6835092
    Abstract: A stacked electrical connector assembly (100) mounted on a main printed circuit board (PCB not shown) includes an insulative housing (1) defining at least two cavities (101, 111), a first and second array of conductive contacts (42, 2) received in the housing, a ground plate (3) disposed between the first and the second contacts, an internal PCB (41) arranged in a rear portion of the housing and an outer shell (5) substantially surrounding the insulative housing. The internal PCB includes a ground trace and a number of signal traces in a galvanic connection with the first array contacts. The ground plate includes a grounding claw (32) electrical connection with the outer shell and a grounding leg (31) coupling to the ground trace of the internal PCB.
