초록 ▼

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.

1. A circuit board for an electrical system having a sub-rack for receiving the circuit board, said sub-rack comprising a chassis contact area, the circuit board comprising: an electrical ground plane; a first grounding contact area electrically connected to said electrical ground plane; and an ejector member pivotally mounted to said circuit board, said ejector member pivotable to an open position and a closed position, said ejector member comprising: a second grounding contact area for contact with said first grounding contact area of said board when said ejector occupies said closed position; a third grounding contact area for contact with said chassis contact area when said ejector occupies said closed position; and an ejection surface engaging said sub-rack upon pivotal movement of said ejector member for ejecting said circuit board from said sub-rack. 2. The circuit board of claim 1 wherein said ejector member further comprises a retaining surface engaging said sub-rack upon pivotal movement of said ejector member for retaining said circuit board in said sub-rack. 3. The circuit board of claim 2 wherein said ejector member further comprises a retaining arm, and wherein said ejection surface is located on said retaining arm. 4. The circuit board of claim 1 wherein said ejector member further comprises a finger tab. 5. The circuit board of claim 1 wherein said second grounding contact area of said ejector member comprises a button, and wherein said grounding contact area of said circuit board further comprises a hole configured to receive said button. 6. The circuit board of claim 1 wherein said circuit board is a printed circuit board member. 7. The circuit board of claim 1 wherein said ejector member comprises a pin having an axis, said ejector member being pivotable about said axis.
