Box for electrical devices, preferably command and signaling devices

The present invention relates to a box for electrical devices, preferably command and signaling devices, which comprises a cover provided with receiving openings for the actuators of built-in devices and a lower part of the box, at the end faces walls with cable entry openings are attached, the cover and the lower part of the box Profile parts cut to the desired length exist, at least one of the profile parts in cross section Is U-shaped and the end walls are screwed to the profile part forming the lower box part, according to FIG Patent (patent application M 71 394-VIIId / 21c).

The box according to the main patent is characterized in particular by the fact that it can be used in any with little manufacturing effort Sizes can be manufactured, including only the profile parts for the cover and box base, which are manufactured by the meter cut to the desired length and put together to form a box with the addition of end walls.

Such boxes must be made tight, which is why the end walls of the main patent are made of elastic, sealing Made of material and sealing profiles between the abutting longitudinal edges of the lid and lower part of the box were inserted. However, it has been shown that these boxes in terms of the design and assembly of the sealing elements can be improved, which is the object of the present invention.

Starting from a box of the type mentioned, the invention achieves this in that the cover is U-shaped is profiled and, engaging in the lower part of the box, with its longitudinal edges on a sealing element lying on the bottom of the lower part of the box, e.g. a rubber plate, is seated, and that the end walls each have a neck-like approach protruding into the interior of the box, on each of which one annular seal is pulled, which sit on the bottom sealing element and on which the cover rests tightly with its frontal hand areas.

109842/0468

In a further embodiment of the invention it can be provided that the two side walls of the cover and the two lateral Sections of the neck-like attachment - seen in cross section - diverge downwards, preferably the two Side walls are elastic and - when the cover is removed - diverge less than the two lateral sections of the neck-like attachment

According to further features of the invention, the neck-like extension or additionally on the inside of the end walls can be provided Projections screw receptacles for attaching the end walls to the box bottom and the lid to the end walls be arranged.

The particular advantage of the box according to the invention is in the fact that its components are manufactured with low manufacturing costs and with little installation effort and with perfect sealing of the box interior can be assembled. Here is the basic one, with the box after the main patent common idea also realized here, namely that the box in any length by cutting off the lid and box lower parts and the plate-shaped sealing element can be produced from corresponding piece goods.

109842/0468

An advantageous further development of the box is achieved by that the side walls of the lower part of the box are made low compared to those of the lid · As a result After removing the cover, the devices built into the box are now freely accessible from all sides

Finally, according to the invention, it can also be provided that the end walls near the bottom of the box at their neck-like Approach or recesses aligned with one another on their projections for inserting a mounting plate with mounting holes for the switchgear to be installed The end walls thus also serve at the same time Bracket for the mounting plate, which is also prefabricated by the meter and cut to the required length can be.

An embodiment of the invention is shown in the drawing shown in the show p

1 shows the box according to the invention in longitudinal section and FIG. 2 shows a section along the line H-II in FIG. 1.

The box consists essentially of a lower box part 1, a cover 2, which contains receiving openings for the actuating elements of built-in devices (not shown), and

109842/0468

from two identically designed end walls 3 · the cover 2 and the lower box part 1 are cut from essentially U-shaped profile parts to the desired length, wherein the lid engages in the lower part of the box and with its longitudinal edges on the bottom of the lower part of the box overlying plate-shaped sealing elements 4, e.g. a rubber plate.

The end walls 3 made of plastic or injection molding have a neck-like shape protruding into the interior of the box Approach 5, on each of which an annular seal 6 is drawn, which seals are on the sealing element on the bodön side 4- sit on and on which the cover 2 rests tightly with its front edge areas.

The attachment of the end walls 3, one on each side Cable entry opening 7 and fastening ears 8 for attachment to a wall or the like. Have countersunk screws 9 »which through the bottom of the lower box part 1 and the bottom sealing element 4- through in threaded holes are screwed in, which are formed in projections 10 on the inside of the end walls 3. As can be seen from the picture is, the end wall 3 is by means of the countersunk screws 9 while clamping the sealing elements 4 and 6 against the lower part of the box tightened. Then the lid. 2 Assembled, the same with screws 11, which are in protrusions

109842/0468

be screwed on the inside of the end wall 3, tightened against the end walls and against the bottom of the lower part of the box, wherein the annular seal 6 and the bottom sealing element 4 are clamped so that the Housing is sealed all around.

As can be seen from 3Pig2, the two side walls diverge 2a, 2b of the cover 2 and the two lateral sections 5a, 5 "b of the neck-like extension 5 downwards, wherein the two side walls 2a, 2b are preferably elastic and - with the cover removed - less diverge strongly than the two lateral sections of the Eals-like attachment 5 < > This makes it particularly easy to put on the cover 2, and at the same time it is possible to that the annular seal 6 is clamped at its lateral portions.

On the projections 10 of the end walls 3 recesses are also arranged, in which a mounting plate 13 can be positively inserted, the with Bohrbohrungen for Attachment of switching elements, command buttons, etc. is provided. Since the side walls of the lower part of the box only protrude little beyond the mounting plate 13, the built-in switching devices after removing the cover 2 of all Pages freely accessible.
