Super Board Clipped to Stiffener
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 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 frames stiffener 6.
