ABSTRACT:
An enclosure for a printed wiring board. The enclosure includes a U-shaped channel member having a ledge in each of its sides. Each ledge has a floor and a wall, and each wall includes at least one projection. A printed wiring board is retained against the ledge floors by means of the projections acting against the printed wiring board. Longitudinal motion of the printed wiring board, in its retained position, is prevented by a tubular projection attached to the U-shaped member extending through an aperture in the printed wiring board. A cover is provided and retained in engagement with the U-shaped member by a plurality of cover projections engaging depressions in a cover receiving ledge formed in the U-shaped member. The enclosure is adapted to be positioned relative to a relay structure by a longitudinal rib attached to the base of the U-shaped member. A fastener extends through the cover and the tubular projection, and engages the relay structure to affix the enclosure to the relay structure.
