ABSTRACT:
A unitized shelf and guide framework for supporting so-called printed circuit cards in spaced alignment. Open-work shelves are joined, for example by welding, in accurate alignment to corner posts to form a frame. Each shelf consists of longitudinal channel members extending in parallel array between end flanges, and may be formed by punch press of a single piece of metal. The channel members are covered by split sheathes, which may be molded of a plastic, and which carry transversely extending alignment bosses for guiding and positioning the circuit cards. A wired back plane of the usual kind is secured in predetermined alignment behind each shelf, and carries the usual receptors for the pin terminals that extend from the back edges of the cards.
