Card Plugging Linkage

      Described is a mechanical linkage used to plug or unplug
the connectors on two circuit cards, which requires up to 70 pounds
of plugging forces.

      The plugging linkage is made up of one pusher link 6, two card
links 3 and two pivots 10 and 11.  The assembly also has four card
holders 4, 5, 7 and 8 which are used to retain the circuit cards 1
and 2.  The card holders 7 and 8 hold the card 2 not allowing it
to move left or right, while holders 3 and 4 allow the card to move
left or right when the linkage is moved.

      The linkage and the card holders are made of reinforced plastic
and are mounted to a steel side cover which is part of the product.

      The card 2 is loaded into holder 7 by depressing plastic
springs built into the holder and then allowing the card to move down
into a slot in holder 8.  The card 1 is loaded into holder 5 by
depressing its springs while at the same time inserting pins which
are located on links 3 through holes in the circuit card and then
allowing the card and linkage to move down where a slot in holder 4
holds the card.  The assembly is then plugged or unplugged by pushing
or pulling the pusher link 6.  The difference between the force on
the card connectors and the force on pusher link is about 10 to 1.
