ABSTRACT:
Disclosed is an enclosure for one or more electrical printed circuit board assemblies. The enclosure features an elongated body portion of U-shaped cross section, and is equipped with flat top and end panels. The assembled enclosure is, accordingly, a six-sided container. On the opposing inner faces of the elongated body section are formed at least one pair of cavities suitable for engaging a flat printed circuit board. The end panels are removable from the opposing ends of the elongated body section. In addition to the cavities formed on the opposing inner faces of the elongated body section for engaging the flat printed circuit board, the enclosure features an additional pair of cavities located on the opposing inner faces of the elongated body section, which lie longitudinally, parallel to the base of the elongated body portion. Each cavity is suitable for accepting a threaded fastener, such as an elongated nut and bolt. The end panels are equipped with openings to allow one end of a threaded fastener to penetrate the end panel, and engage with a corresponding threaded fastener lying within a similar set of cavities in an adjacent enclosure. By this method, a series of the described enclosures may be physically secured together.
