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.
