  • Publication number: 20200295541
    Abstract: A micro power distribution block comprises: an enclosure; a connector, the connector comprising a power input terminal, a power output terminal, a ground terminal, and a reset terminal; and a circuit member disposed within the enclosure and operatively connected to the connector. The circuit member includes a relay coupled to the power input terminal. The relay is configured to switch between an ON state and an OFF state. The circuit member also includes a feedback sensor configured to sense power flow through the relay in the ON state. The circuit member further includes a control circuit configured to: (a) generate a relay control signal for switching the relay from the ON state to the OFF state based on a magnitude of the sensed power flow, and (b) receive a reset signal, via the reset terminal, for switching the relay from the OFF state to the ON state.

  • Patent number: 7018239
    Abstract: A shielded electrical connector is provided for mounting on a printed circuit board. The connector includes a dielectric housing having a plurality of terminal-receiving cavities and a plurality of board-engaging pads projecting from the bottom of the housing. A plurality of terminals are received in the cavities. Portions of the housing between the terminals are plated with conductive metal material to electrically shield the terminals from each other and to provide a controlled impedance. The plating is continuous onto the pads for connection to appropriate ground circuit means on the printed circuit board. In an alternative embodiment, a shielded electrical connector assembly includes a pair of connectors both of which have plated housings with interengaging plated portions.
