Abstract

Disclosed is a mechanical device that inserts/removes daughter cards to a mother board when the mother board is perpendicular to the service side of the package. This device also provides a mechanical advantage to insert/remove cards when the connector mating force is higher than what a typical person could apply without using tools.

Mechanism

      Disclosed is a mechanical device that inserts/removes daughter
cards to a mother board when the mother board is perpendicular to the
service side of the package.  This device also provides a mechanical
advantage to insert/remove cards when the connector mating force is
higher than what a typical person could apply without using tools.

      Conventional card on board packaging consists of daughter cards
plugging perpendicular to the mother board.  The daughter cards plug
straight on the board.  This works fine when vertical cooling of the
package is acceptable, but in rack mount products where horizontal
cooling is a requirement the mother board blocks or impedes forced
air cooling.

      The card cam device allows the mother board to be positioned
horizontally to allow for horizontal cooling, yet still be able to
insert/remove cards from the vertical face of the product.  For rack
mount products there is only the front and back surfaces exposed to
service the product when mounted in the rack.  Typically the product
is mounted on slides to gain access to other sides on the product,
but when this is not acceptable, then a card cam device could be used
to remove/inserts cards from a horizontal mother board.  Other
applications could be desk top products such as personal computers.
Here the mother boards are horizontal to keep a low profile.  With
this device the cards could be removed/inserted without taking the
cover off.
