Super Board Clipped To Stiffner

This card-board assembly includes a large printed circuit board 1 which is designed to accommodate rows of pluggable cards 2.

Circuit board 1 is a multilayer, epoxy-glass laminate having a plurality of connection pins 3 extending from both sides of the board. The portion of pins 3 extending upwardly mates with the connectors 4 affixed to cards 5. The portion which extends on the other side can be used for wire wrap interconnections. Since circuit board is a re wrap interconnections. Since circuit board 1 is a relatively flexible member, a frame stiffener 6 is included. This is a molded plastic part with the two alignment pins 7 which pass through corresponding holes 8 in board 1.

Latch members 9 retain board 1 in engagement with stiffener 6 without the need for screws, rivets or other mechanical fasteners.

The connectors 4 on cards 5 are guided into engagement with pins 3 by means of connector guides 11. Alignment pins 7 extend upwardly through holes 8 and mate with holes 12 in guides 11. The guides 11 have bosses on the bottom side concentric with holes 12. These bosses fit holes 8 and locate the guides 11 on the board in relation to the pins 3.

A pair of hold-down blocks 14, which retain the connector guides 11 in place, are held in position by latch members 13 at the corners of frame stiffener 6.
