Abstract
A printed circuit board employs a rigid toothed drive arm driven by an exterior spur gear to actuate a pair of levers pivotably attached to one end of the drive arm. Spur gear rotation moves the drive arm and variously moves the drive arm and levers into “Y” or “T” configurations, and in doing so, pushes against exteriorly mounted cabinet or enclosure pins to effect inward and outward motion of the entire board, even when it is fully populated with printed circuit cards contained in cooperatively acting cartridges.
Claims10
A circuit board assembly including a mechanism for insertion and removal of said circuit board, said assembly comprising:
- a circuit board having an electrical connector affixed to a rear edge thereof;
- a rigid nonconductive base to which said circuit board is affixed;
- a rigid driving arm disposed as to be forwardly and backwardly moveable within a first slot disposed within said nonconductive base;
- at least one lever arm pivotably attached to said driving arm and including a pin therein which rides in a second slot disposed substantially perpendicularly to said first slot, said second slot also being disposed within said nonconductive base;
- and
- a moving mechanism affixed to said board or base for urging said driving arm in forward and backward directions within said first slot for insertion and removal operation, wherein said lever arm is pivotably moved by said driving arm whereby said lever arm is also capable of engagement with at least one stationary off-board fixture against which force may be exerted by said lever arm for insertion and removal operations.
