Abstract

A card connector system is provided which permits a card to be plugged or unplugged from a functioning board, and replaced by another card, while the associated machine in the system is operating. This result is achieved by providing a plurality of connecting pins having different heights, so that electrical connections can be interrupted or closed at different times or sequences during removal or insertion of the cards.

Card Connector System

       A card connector system is provided which permits a card
to be plugged or unplugged from a functioning board, and replaced by
another card, while the associated machine in the system is
operating.  This result is achieved by providing a plurality of
connecting pins having different heights, so that electrical
connections can be interrupted or closed at different times or
sequences during removal or insertion of the cards.

      As shown in the drawing, a printed circuit card 1 is provided
with a plurality of edge connectors 3 comprising spring elements
electrically connected to circuits and components on card 1.  On
board 5, on which card 1 is to be mounted, there are provided a
plurality of connecting pins 7, 9 and 11, of differing lengths, which
mate with correspondingly located edge connector contacts 3 on card
1.

      Since the pins 7, 9 and 11 have different lengths, it is
apparent that the connections will be established at different times
and different sequences as the card 1 is mated with board 5.  This
permits the functional circuits to be connected or disconnected in
the required sequences, so that the cards can be inserted and/or
removed without disturbing the operation of the system.
