Abstract
Mezzanine boards can be added to and removed from a supporting base board mounted in a slot of a shelf adjacent other base boards while the base boards remain in electrical service. Guide rails allow a mezzanine board to be slid into position from the front edge of the base board. The guide rails themselves can be moved to provide a new spacing to accommodate a different width mezzanine board without having to take the supporting base board out of service. Openings in the sides of the guide rails promote the flow of air between the mezzanine board and the base board to provide cooling.
Claims17
An assembly of circuit boards comprising:
- a base board;
- a faceplate disposed substantially perpendicular to the plane of the base board and mounted along one edge of the base board;
- spaced apart mounts attached to the base board;
- guide rails extending away from the plane of the base board and attached to the base board by the mounts, the guide rails including at least one longitudinal channel;
- at least one mezzanine board having opposing longitudinal edges;
- first and second channels in first and second guide rails are dimensioned to receive first and second longitudinal edges of the mezzanine board, respectively;
- the faceplate having at least one aperture dimensioned to accept the at least one mezzanine board and provide access to the first and second guide rails so that the first and second longitudinal edges of the at least one mezzanine board can be slid into the respective first and second channels.

An assembly for supporting at least one mezzanine board having opposing longitudinal edges, the assembly comprising:
- a base board;
- spaced apart mounts attached to the base board;
- first and second guide rails extending away from the plane of the base board and attached to the base board by the mounts, the first and second guide rails including at least one longitudinal channel;
- first and second channels in said first and second guide rails are dimensioned to slidingly receive first and second longitudinal edges of the mezzanine board, respectively;
- the mounts comprising longitudinal members that include one of a longitudinal extending channel and a longitudinally extending projection dimensioned to slide within the channel, and the guide rails include the other of a longitudinal extending channel and a longitudinally extending projection dimensioned to slide within the channel.
