The invention relates to installation housings for electrical equipment, in particular Viand installation housings, which are shown in when empty, they can be stacked one inside the other and are provided with easily insertable and removable walls. The known housing of this type, both rectangular and circular, have two opposite sides inwardly protruding elements with openings for fastening the screws of the to be installed Device holder These elements prevent the housings from stacking one inside the other. This condition makes it difficult to store and transport such housings, primarily because of the large amount of space they take up.

With these installation housings for electrical equipment, which are built into the V / and and two or more To include electrical devices next to each other, it is also necessary to have inner partitions made of insulating material to prevent contact between the various power lines for the equipment. One has

seeks to remedy this drawback, either by means of partitions fixedly connected to the housing, which the

The invention overcomes all of these deficiencies

The one-piece installation housing according to the invention for electrical equipment, in particular for installation in
Walls are characterized by the fact that they consist of a vo ^ - \ their or upper further part and a lower or
rear narrower detached part, which latter
in the former when stacking is insertable that

maintenance of these projections has outwardly open grooves in which when two housings are stacked one inside the other
the protrusions fit into it.

Furthermore, the lower part has one or more opposite sides on the other opposite sides of the housing -Rare- -dee-oooo -ee ee lying inwardly open guide grooves with strip-like edges for inserting partition walls. j

Furthermore, at the bottom of the lower part is one of the two]

Finally, the upper part has, above the guide grooves, protruding stops on the inside for partition walls to be inserted. \

The partition to be used (or "partition walls") consists of! an elastic flexible material and corresponds in its height <speaking the widths of the upper and lower part of the housing formed discontinued accordingly. ;

The subject matter of the invention will be explained, for example, using the drawings, which show:

Pig »1 is a perspective view of the housing with a

Partition wall ;

Fig. 2, in section, the stacking of several housings:

Fig. 3 in Sjfuerschnit "; a housing with an inserted Partition wall.

According to the drawings, the housing 1 has a front part 2 on, the dimensions of which are designed so that it includes the intended number of electrical equipment can be. Two projections 3 and 4 are provided on two opposite sides of the housing, in this case in the form of ribs that run directly perpendicular to the bottom of the housing. These projections have the Holes 5 and 6. by means of which the support frame of the electrical equipment is attached to the housing by screws will. The rear part 7 of the housing 9s has smaller dimensions than the front one and is limited by a continuous, inwardly projecting stop 8. Of the rear part 7 can thus be pushed firmly and almost exactly into part 2. To avoid canting when inserting To avoid the elements 3 and 4, corresponding outwardly open grooves 9 and 10 are provided, which on the bottom start on opposite sides of the housing. These grooves are able to accommodate the projections 3 and 4, respectively.

Inside, the housing contains grooves running perpendicular to the partition walls to be inserted; 12a and 12b on one wall, an exactly symmetrical groove being provided on the opposite wall.

These grooves start at the bottom of the housing and reach height 8, thereby preventing the ineinaxiderstackeln Housing in no way

These grooves can be used both through indentations on the wall; can be achieved, or, as in the case shown, duuren \

Strips 14 and 15 which protrude perpendicular to the inner walls of the housing. Those who are at the same height Grooves can be connected to one another by a bottom groove 16, these too by two strips 17 and 18, the ■ rom testicle iy hoch.gtehenj is formed.

Above every vertical groove and at a certain distance of which a stop 20 is provided, which has a stop edge 21 on the underside, the width of which must not be less than that of the groove. To introduce a partition 22, its vertical sides 23 and 24 inserted into two opposing grooves of the housing, the wall 22 being elastically not bent to come into contact with the stop 20.

When the wall engages in the bottom groove 16, it is released, so that it is now elastically straightened again, whereby the upper V / and edges 25 and 26 under the stop edge 2 ies stop 20 to lierpr. come (see Fig. 3). This secures the partition wall, but it can be bent at any time can be pulled out again.

Au3 Fig. 2 it can be clearly seen that this type of housing can be stacked one inside the other in a simple way, with only the rear part 7 of a housing in the front Part 2 of another housing needs to be pushed. All you have to do is use the outer grooves 9 and 10 Bring projections 3 and 4 into alignment and close that Insert stacking housings up to stop 8 in the receiving housing.

The right-angled housing in the drawings can also be square or round »
