Abstract

A logic card 10 used in an electrical chassis is rendered replaceable by the user, rather than by a Customer Engineer, by completely enclosing the logic card 10 within a molded, two-piece cartridge 11. The cartridge protects logic card contacts 12 and components 13 when the card is removed, and exposes contacts 12 for electrical connection when cartridge 11 is inserted into an electrical chassis. Vent holes in cartridge 11 permit air circulation within the cartridge, for logic card cooling.

Replaceable Logic Card Cartridge

A logic card 10 used in an electrical chassis is rendered replaceable by the user, rather than by a Customer Engineer, by completely enclosing the logic card 10 within a molded, two-piece cartridge 11. The cartridge protects logic card contacts 12 and components 13 when the card is removed, and exposes contacts 12 for electrical connection when cartridge 11 is inserted into an electrical chassis. Vent holes in cartridge 11 permit air circulation within the cartridge, for logic card cooling.

Cartridge 11 is inserted into an electrical chassis (not shown) using guide grooves 14 and 15 for alignment. Actuating handle 17 is moved from its open position (up, as shown in solid line) to its closed position (down, as shown in dotted line). Downward movement of handle 17 pivots cam 18 and thereby moves card 10 laterally in cartridge 11 to expose contacts 12 for connection with mother board land patterns (not shown). Latch 16 locks cartridge 11 in place.

Cartridge 11 may be removed by moving handle 17 to its up position, thereby retracting card 10 laterally into cartridge 11 to protect contacts 12, and releasing latch 16 via spring 19.
