Abstract

The arrangement shown and described herein provides a means for retaining a printed circuit card in its proper position in an assembly in which the printed circuit card is incorporated into a cover assembly unit. Printed circuit card 1, bearing circuit components 3, is placed in a cover sub-assembly 4 (Fig. 1). The card 1 is positioned with its edge 1A engaging stops 5 integrally formed on side 4A of member 4 and the locator notch in 2 (Fig. 2) seated on locator element 8 integrally formed on opposite sides 4B of members 4. Removable biasing pads 7 are then inserted into the openings or sockets 6 also integrally formed on side 4B. Pads 7 are made of material, e.g.

Printed Circuit Card Biasing Pad

The arrangement shown and described herein provides a means for retaining a printed circuit card in its proper position in an assembly in which the printed circuit card is incorporated into a cover assembly unit. Printed circuit card 1, bearing circuit components 3, is placed in a cover sub-assembly 4 (Fig. 1). The card 1 is positioned with its edge 1A engaging stops 5 integrally formed on side 4A of member 4 and the locator notch in 2 (Fig. 2) seated on locator element 8 integrally formed on opposite sides 4B of members 4. Removable biasing pads 7 are then inserted into the openings or sockets 6 also integrally formed on side 4B. Pads 7 are made of material, e.g. plastic, having a resiliency chosen to permit them to be forced into place in the receiving sockets 6 but yet are stiff enough to resist any forces tending to displace them. Each pad 7 has a snap-on or locking feature provided by its integrally formed bifurcated members 9 (Fig. 3). The contact area 11 of pad 7 contacts the edge 1B of card 1 to hold it in position in the cover sub-assembly 4.
