with a PC board during the insertion and removal operations. This offset end has a
vertical groove 41 for engaging an edge of a board during insertion and an ejection pin
42 for engaging a slot 74 in the board during removal. As described by Wong,
To insert a PC board 55 using the present invention, PC board 55
is pushed manually into its slot 56 in card cage 50 until the connectors
carried by PC board 55 and card cage 50 (not shown) meet. Next, slider
30 with arm 40 attached is moved along guide 20 until groove 41 aligns
with the edge of the PC board, as shown in FIG. 1A. To insert PC 55
board fully, a tab 51 of arm 40 is pulled in the direction of arrow 72 (FIG.
1A) until groove 41 comes in contact with PC board 55. Further pulling
causes PC board 55 to be pushed further into card cage 50 until the
connector parts carried by PC board 55 mate with the corresponding
backplane connector parts of card cage 50. Releasing tab 51 allows
spring 49 to return arm 40 to its normal, vertical position.
In a similar fashion, when tool 10 is used to remove a PC board
from the card cage, slider 30 is moved along guide 20 until arm 40 is to
one side, to the right in FIG. 1B, of PC board 55 to be removed. Tab 51 is
then lifted a small amount until pin 42 on arm 40 aligns with a slot 74 in
PC board 55. Tab 51 is then lifted slightly so that pin 42 will fit into slot 74
on PC board 55. Once pin 42 is in position, pushing down on arm 40
causes the connectors to unmate, and PC board 55 moves in the direction
of arrow 75 out from card cage 50. Slider 30 and arm 40 can then be
moved out of the way and PC board 55 fully removed [column 2, lines 31-
57].
