Abstract
Abstract The present invention relates to housings, particularly module carriers, equipped with supporting rails for the accommodation of a plurality of mutually parallel guide rails into which plug-in units equipped with electronic and electric components can be inserted. According to the invention, unoccupied plug-in locations are covered by individual covers whose width essentially corresponds to a multiple of the smallest scale unit and which can be combined in any desired number so that the air flow in the housing or in the module carrier is improved in a simple manner.

Total Claims: 19
Claim 1
Independent Claim
144 words
In a housing, particularly a module carrier, including supporting rails to accommodate a plurality of mutually parallel guide rails into which plug-in units having electronic and electrical components can be inserted; and a covering arranged to cover unoccupied plug-in locations; the improvement wherein the covering is composed of individual covers securable to the supporting rails; the covers having a width essentially corresponding to a multiple of the smallest scale unit; said covers being combinable in any desired number; each cover having an upper wall, a side wall, a front wall and a rear wall; each cover being individually securable to the supporting rails by means of at least two mutually oppositely oriented spring catches disposed under the upper wall; further wherein said front wall and said rear wall is provided with recesses for the passage of a tool to disassemble a selected said cover.
