  • Publication number: 20020076988
    Abstract: An electrical connector (1) includes an insulative housing (2), first and second terminal modules (3), (4), first and second insulative covers (5), (6), a pair of board locks (7) and a conductive shield (8). The first and second terminal modules each includes a dielectric spacer (30), (40) and a plurality of electrical terminals (32), (42) extending through the dielectric spacer. The first and second covers each defines a plurality of bottom passageways (54) for partially accommodating the electrical terminals of the first and second terminal modules, respectively. The shield includes a top wall (80) being separated from the electrical terminals by the dielectric spacers and the insulative covers.

  • Patent number: 6379181
    Abstract: An electrical connector (1) comprises an insulating housing (10) receiving a plurality of terminals (20) therein. A pair of grounding devices (50) and locking devices (40) are assembled to the housing and engage with each other. The housing defines first and second receiving slots (16a, 16b). The housing also defines an arced recess between the first and second slots. Each locking device comprises first and second locking arms (44, 46). A circular nut (48) is integrally formed with the first arm, and is fittingly received in an arced lower portion of the arced recess. The nut threadedly engages with a locking portion (56) of a corresponding grounding device.

  • Patent number: 6299461
    Abstract: An electrical connector comprises an insulative housing (3), a number of terminals (4), two rivets and a fixing device (5). The housing (3) forms a D-sub projection (31) defining a number of passageways (32). The fixing device (5) engages with the housing (3) by rivets. The fixing device (5) has four boardlocks (51) extending through a circuit board (6) to suspend the housing (3) beyond an edge of the circuit board (6). Thus, occupied space on circuit board (6) can be conserved.
