Abstract
An apparatus for locking a printed circuit board inside a card cage is disclosed. For one embodiment of the locking assembly, the locking assembly is mounted on a printed circuit board. The locking assembly is movable from a unlocked position to a locked position to lock the printed circuit board into the card cage. The locking assembly is unmovable to return to the unlocked position without the aid of a separate unlocking mechanism.
Claims20
An apparatus, comprising:
- (A) a printed circuit board;
- (B) a card cage;
- and
- (C) a locking and latching assembly mounted on the printed circuit board, the locking and latching assembly including a lever and a latch, wherein the locking and latching assembly is movable from an unlocked position to a locked position to lock the printed circuit board into the card cage, and wherein the latch is held in an engaged position such that the locking and latching assembly is unmovable to return to the unlocked position without applying a separate mechanical unlocking mechanism to the latch.

A locking mechanism comprising:
- a face plate attached to a printed circuit board, said face plate having a first opening;
- a lever rotatably mounted on said face plate, said lever having a second opening;
- an extractor rotatably mounted on said face plate and attached to said lever such that said extractor rotates with said lever;
- and
- a latch rotatably mounted on said lever, wherein when said lever is moved to a locked position said extractor locks said printed circuit board into a card cage and said latch is engaged with said first opening locking said lever in said locked position, wherein said lever is released to an unlocked position by inserting a separate unlocking mechanism through said second opening such that said separate unlocking mechanism rotates said latch to disengage said latch from said first opening.
2 more elements
An apparatus comprising:
- a printed circuit board;
- a card cage for housing said printed circuit board, said card cage having a connector for electrically connecting circuitry on said printed circuit board with other circuitry housed in said card cage;
- and
- a mechanism for locking said printed circuit board into said card cage, said mechanism having
- a) a face plate attached to said printed circuit board, said face plate having a first opening;
- b) a lever rotatably mounted on said face plate, said lever having a second opening;
- c) an extractor rotatably mounted on said face plate and attached to said lever such that said extractor rotates with said lever;
- and
- d) a latch rotatably mounted on said lever, wherein when said lever is moved to a locked position said extractor locks said printed circuit board into said card cage and said latch is engaged with said first opening locking said lever in said locked position, wherein said lever is released to an unlocked position by inserting a separate unlocking mechanism through said second opening to move said latch to disengage said latch from said first opening.
