Housing for the accommodation of electrical assembly carriers
First Claim
1. A housing containing a plurality of circuit boards comprising, modular, parallelepiped-shaped housing units which are stacked above each other on a base surface and which are provided with mechanically stable sidewalls connected to one another by horizontal fixing plates which extend along the upper and lower edges of each modular unit in planes parallel to the base surface, and between the plates the circuit boards are detachably arranged in planes parallel to the sidewalls, said sidewalls are provided with locking recesses which are designed in a manner such that rigid connecting elements are located in the locking recesses of two adjacent housing units, the mechanically rigid connecting elements being each provided with a spacer so as to form a slot of substantially constant width between adjacent housing units wherein the sidewalls are provided with reinforcing elements which extend along the interior face in the vertical direction, and which are connected to the horizontal fixing plates in the region of the upper and lower edges of the sidewalls, wherein the region of the upper and lower edges of the sidewalls of the reinforcing elements are each provided with a horizontal cut-out which accommodates an edge portion of a respective horizontal fixing plate.

Abstract
A housing consists of modular housing units 1 which can be stacked one above another and beside each other and which are provided with mechanically stable sidewalls 11. Between the sidewalls 11 of vertically adjacent housing units 1, a slot is formed which takes up variations and irregularities in the adjacent sidewall edges and permits mechanically stable connection and simultaneous electrical connections to laterally adjacent housing units 1. The housing does not have a separate frame for the accommodation of the circuit boards. Horizontal locking plates 12 connect the sidewalls 11 and provide both guide rails for the circuit boards and cooling openings.
