Abstract

This latch automatically locks printed circuit card 14 into frame 18 when such card is inserted into the frame. Initially levers 10 and 12 are upright so as to allow card 14 to be slipped through them into grooves 16 along the sides of frame 18. The stiffened edges of card 14 slide freely into frame 18 until lugs 20 on card 14 engage extensions 22 on levers 10 and 12. This causes levers 10 and 12 to pivot around points 24 so that levers 10 and 12 assume a horizontal position where lips 26 on the arms engage ledges 28 on the upper edge of card 14 to lock the card in position. To extract card 14 from frame 18, the ends of levers 10 and 12 are grasped and pulled apart so as to raise levers 10 and 12 in a vertical position.

Latch

This latch automatically locks printed circuit card 14 into frame 18 when such card is inserted into the frame. Initially levers 10 and 12 are upright so as to allow card 14 to be slipped through them into grooves 16 along the sides of frame 18. The stiffened edges of card 14 slide freely into frame 18 until lugs 20 on card 14 engage extensions 22 on levers 10 and 12. This causes levers 10 and 12 to pivot around points 24 so that levers 10 and 12 assume a horizontal position where lips 26 on the arms engage ledges 28 on the upper edge of card 14 to lock the card in position. To extract card 14 from frame 18, the ends of levers 10 and 12 are grasped and pulled apart so as to raise levers 10 and 12 in a vertical position. This causes extensions 22 to engage lugs 20 and thus pull card 14 out of frame 18 so the card can then be fully extracted from the frame by grasping its edge.
