Circuit Card Cover and Bracket Hinge

This one-piece, molded polypropylene card cover and bracket-hinge assembly 10 outwears a foam rubber padded steel plate assembly. Cover portion 12 and bracket portion 14 are joined by hinge portion 16 along one edge. Assembly 10 is fastened into the card gates, not shown, by screws passing through two holes 18 at the top and two more at the bottom, not visible. Cards 20 indicate the position of the assembly relative to the card gate.

The corrugated surface, seen in the cross-section of the inset, provides the resilient element for urging cards 20 into the sockets not shown. In use, cover portion 12 is locked into the bracket portion 14 by two complementary ratchets 21 and 22 and 23 and 24. To open the cover, ratchets 21 and 23 are flexed away from the bracket ratchets 22 and 24.

Gap 26 in bracket portion 14 results from the mold. The latter is arranged with bracket portion 14 flexed away from the sides and top of cover portion 12 so that assembly 10 can be molded in one piece. The corrugations can be thin for flexibility and relatively thicker for rigidity. By changing the thickness and shape of the corrugations varying degrees of flexibility and rigidity can be obtained.
