  • Circuit board having an emission reducing ejector
    Publication number: 20040207992
    Abstract: An electrical system comprises an electrical circuit board for mounting electrical components and a circuit board sub-rack. The board includes a pivotally mounted ejector member which pivots to insert and eject the board from the sub-rack. The ejector member carries two grounding contact surfaces for engagement with the ground plane of the board and chassis area of the sub-rack when the ejector member is pivoted to its closed position. The contact surface of the ejector member mates with the board to frictionally hold the board in fully inserted position. The ejector member also includes a retaining arm which mates with the sub-rack for providing an insertion or ejection force to facilitate insertion or ejection of the board relative to the sub-rack.

  • Circuit board with connector guide
    Patent number: 6302700
    Abstract: A circuit board defining a flange is used to interconnect conductors located on the flange with corresponding conductors of a conventional connector. The flange includes a key slot and two flange slots which promote alignment between the circuit board and the connector. The flange slots define a mouth with an angled edge which urge the connector into alignment with the flange slots.
