    Abstract: An improved electromagnetic interference shield for a module includes springs in which the compression force pushes the springs in a direction that is approximately parallel to the optic axis. The springs allow significantly looser tolerances on the placement of the module on its associated printed circuit board. The shield also includes an opening near its center, the edge of which includes a plurality of teeth. When the shield is placed onto the module, the teeth bend along the negative optic axis direction and prevent the shield from being pulled away from the module. Accidental removal of the shield is thus prevented. The shield splits the enclosure ground from the internal signal ground, decreasing the capacitance between them, in turn decreasing another possible source of electromagnetic radiation. In addition, the shield is more cost efficient to manufacture since it only requires a one step assembly process.

  • Patent number: 6786742
    Abstract: A cable connector allows the electrical contacts thereof to come into elastic contact with a ground plate when the cable connector connecting with a shielded cable is fit-connected to a PCB connector through the ground plate. The contact effectiveness of the electrical contacts is improved so that a shield-ground path from the shielded cable to the ground plate has a low impedance. The connector is provided with electrical contacts which are composed of generally U-like bent spring plates. Each spring plate is supported at one end thereof on the shield shell, and comes into elastic contact with the ground plate when the cable connector is fitted into the mating connector.

  • Patent number: 6780029
    Abstract: A fitting for securing an electrical cable to an electrically conductive junction box that provides improved electrical continuity between the fitting, the cable, and the junction box. The fitting features a hollow electrical connector having an electrically conductive split snap ring surrounding its leading end. The snap ring includes one or more grounding tangs cantilevered from its outer circumference and a locking tang lanced from each grounding tang. By providing locking tangs integral with the grounding tangs, a greater portion of the periphery of the snap ring is available for forming the grounding tang. The larger grounding tangs provide much greater surface contact between the grounding tangs and the junction box, thereby improving continuity and lowering the millivolt drop.

    Abstract: The invention relates to a plug-in connection between a printed-board connector (3) and a mating connector (13), said printed-board connector (3) being provided with a connector shield (6). Between the printed-board connector and the mating connector an I/O board (1) with an opening (2) is interposed via which the printed-board connected and the mating connector can be contacted and fastened to each other. Since the printed-board connector is not screwed together with the I/O board according to the most recent standard, a support element is provided which forces the I/O board (1) against the connector shield (6) of the printed-board connector (3) when the mating connector (13) is screwed together with the printed-board connector (3).
