Abstract

As printed circuit cards become larger and require more contacts to connect them to the rest of the system, it becomes difficult to unplug them without damage to the card or the contacts. The problem is compounded by the fact that the cards are generally mounted in tight quarters with little room for the use of extraction tools or expensive complex lever arrangements.

Card Jack Ejector System

As printed circuit cards become larger and require more contacts to connect them to the rest of the system, it becomes difficult to unplug them without damage to the card or the contacts. The problem is compounded by the fact that the cards are generally mounted in tight quarters with little room for the use of extraction tools or expensive complex lever arrangements.

In the printed circuit card extraction system shown, above a card 1 is adapted to be plugged into the set contact pins 2 on circuit board 3. The ends of card 1 have jack holders 4 end 5 which hold jacks 6. Each jack has a screw slot 7 at the top and a spade-like point 8 at the bottom. The spade points fit into barrels 9.

The barrels 9 each have two ramps 10 and 11 inside, as shown in Fig. 2. The printed circuit ramp 10, which is higher than ramp 11 and shaped to a point. causes jack 6 to rotate so that it does not hang up as the card is inserted.

The card is ejected by inserting a screwdriver into slot 7 and rotating jack 6. This causes spade point 8 to ride up ramps 10 and 11 to eject the card.
