DE1765396B2 - Box for electrical devices, preferably command and signaling devices - Google Patents

Description

The present invention relates to a sealed one Box for electrical devices, preferably command and signaling devices, welchei one with receiving openings for the actuation ^ 'ieder of built-in devices provided cover and a box part includes, of which at least the cover is U-shaped in cross section and wherein to the Front sides of the lower box part walls with cable entry openings are attached, the or the U-shaped box parts made of extruded profile material cut to the desired length consist, whereby the end walls screwed to the lower part of the box are made of a metal plate and an elastic piece of material, e.g. B. made of rubber, and with clamping this elastic Part of the material are tightened tightly against the box lower part, the elastic material part at least in the area of the lid has a section located inside the box and with the lid under Clamping a seal assigned to its longitudinal edges while simultaneously pressing tightly against it the sections of the elastic Stirawandteile is attached to the box base, according to patent 1,665,081.

ίο The box after the main patent stands out in particular because it can be manufactured in any size with little manufacturing effort can, for which only the profile parts for cover and box base, which are manufactured by the meter, are attached to each Cut off desired length and put together to form a box with the addition of end walls will.

Such boxes must be made tight, which is why the end walls of the main patent are partially made of elastic, sealing material and placed between the butting Longitudinal edges of the lid and lower part of the box sealing profiles were inserted. However, it has been shown that these boxes in terms of design

»5 and assembly of the sealing elements improved which is the object of the present invention.

Based on a box of the type mentioned, the invention achieves this by that the seal associated with the longitudinal edges of the lid is on the bottom of the lower part of the box is the overlying sealing element on which the lid, engaging in the lower part of the box, rests, that the elastic material parts of the end walls are each annular seals, which on a into the box interior protruding neck-like approach of each end wall are raised, and that the Seals sit on the bottom sealing element and on them the cover with its front Lies tightly at the edge areas.

In a further embodiment of the invention it can be provided that the two Seitenir.vände the Lid and the two lateral sections of the neck-like attachment - seen in the cross section - diverge downward, the two rope walls are elastic and - when removed Lid - diverge less than the two lateral sections of the neck-like attachment.

so according to further features of the invention can on the neck-like attachment or on projections additionally provided on the inside of the end walls Screw receptacles for attaching the end walls to the box floor and the cover to the end walls be arranged.

The particular advantage of the box according to the invention is that its components can be manufactured at low manufacturing costs and can be assembled with little installation effort while the interior of the box is perfectly sealed. The basic idea shared with the box according to the main patent is also realized here, namely that the box can be produced in any length by cutting off the cover up 'box base and the plate-shaped sealing element from corresponding meter goods.

An advantageous development of the box is

achieved by the fact that the side walls of the Kaslennn-

Finally, according to the invention, it can still be seen in front of the bottom of the lower part of the box and that the end walls are screwed into the box-bottom sealing element 4 bJndurcn near their neck-like attachment or at their projections mutually aligned recesses on the inside of the end walls 3 for inserting a f formed nd with mounting holes for As shown in the figure * 2, ^B ^ ~ ^s, the incorporated switchgear assembly provided io the countersunk screws 9 have the end wall 3 by ^ chipboard.
