Printed circuit card guide

Claim 1

A printed circuit card guide system including a back panel member to which at least one connector is affixed, said system further including a card guide comprising: A. first and second elongated base members, each said base member having a first end and a second end and first and second opposite sides; B. a slot extending along said first side of each of said first anD second base members between respective first and said second base member ends, each said slot being tapered wider at its said first end to facilitate introduction of first and second printed circuit card edges into said slots; C. said second end of each said base member defining a trunnion configured and dimensioned to closely receive the connector; D. a plurality of L-shaped tangs distributed along the length of said second sides of each said base member, each of said Lshaped tangs having a first arm extending outwardly and a second arm extending toward said respective second of each said base members end; E. a locking tab disposed proximate said respective first end of each of said base members, each said locking tab extending outwardly from said second side of said respective base member and generally parallel with said first arms of said tangs distributed along the length of said second side of said respective base member; F. support means for said first and second base members fixed in position with respect to said back panel, said support means having parallel upper and lower series of elongated slots disposed in alignment with said connector, said elongated slots of each series being dimensioned and distributed to loosely receive said tangs of one of said base members, said support means further having first and second locking apertures, each of said locking apertures being positioned and dimensioned to tightly receive one of said locking tabs; whereby said base members may be rigidly and accurately affixed to said support means, in parallel disposition to one another with said slots facing each other, by engaging said trunnions with said connector and said tangs of said first and second base member respectively with said first and second series of elongated slots and subsequently engaging each of said locking tabs with the corresponding one of said locking apertures, said first and second base member thus comprising a card guide for receiving two edges of a printed circuit card.
