Description

the German patent HRiSTiAN Geyer. Nuremberg an amt, Munich from: February 23, 1966 Biattl

* ty * 9 · Ί 9 VP box for electrical distribution systems

The innovation relates to a box for electric Distribution systems for the installation of fuses, busbars, switches, etc. made of insulating material. There are boxes for electrical ones Distribution systems have become known, which consist of a lower part and a cover and, however, the lower part only has openings on two opposite sides that are open to the front. Through these openings are Busbars guided or inserted from the front. On the lower side wall, however, in this known embodiment, the opening is not open to the front. The disadvantage Such a design consists in the fact that the cable cannot be inserted from the front.

There are also scaffolding elements in table form known, di © after Type of the modular system can be put together to form low-voltage switchgear and where the table shape is naohteiligerweise of the frame is designed so that the plate is shaped like a fish shows at the front, so acts as a cover. This results in line guide openings that are not open towards the front.

a junction box has also become known, which is also used as a cable box and which has large openings, which are open to the front. However, this was never used for boxes for electrical distribution systems because of the Design of the side part inserts the lower part is not stable enough. In the case of hard, age-resistant seals that are in Boxes of such systems are common, the corner posts of these lower parts would be stressed on wedge effect. A verse

Screwing the side part inserts directly to the lower part is not intended, but the inserts only inserted into grooves in the side walls.

Furthermore, a junction box has become known which also has openings that are open towards the front be able. Such a distribution box has exchangeable side walls. The side walls are created from a profile. The disadvantage of this distribution box is that the profiles do not have the necessary stability, which is required in particular for the side walls in the area of the cable entries of boxes for the above-mentioned purposes is. The innovation has set itself the task of addressing the aforementioned disadvantages in a box for electrical distribution systems For installing fuses, busbars, switches, etc. made of insulating material, consisting of a high, one-piece Lower part, with a wall-side base, with side walls, with a cable termination preferably in at least one side wall can be flange-mounted and the side walls have large insertion openings, with a cover and with the side walls of the lower part attachable and veraubbaren closure plates, to be eliminated by the fact that the openings in the Side walls open at the top and the closure plates have pressure edges which are moved inwards so that this together with the printed edges of the lower part form a closed, Form circumferential pressure edge course of the lower part.

Further details of the innovation are "for example the description and the figures. Show it:

Pig. 1 A top view of a box base, with a second lower part of the box is partially drawn. The dashed line shows a cable termination,

Fig. 2 is an end view of the lower part of the box,

Fig. 5 is a side view of the box lower part together with Lids and locking plates,

Fig. 4 is a section along the line a-b of fig. I, where the The lid is broken off,

Fig. 5 is a section along the line c-d of Fig. 1, wherein two deeke broken off are also marked,

6 shows a side view of a closure plate, FIG. 7 shows a plan view of a strip and 8 shows the bar together with two boxes lined up next to one another, the bar and the two boxes broken off, are shown.

The lower part 2 has openings 14 on all four sides for the introduction of lines etc., which are open at the top.

The pressure edges of the lower part are denoted by 1 and can - as in the example in FIG. 1 - at the same time the inner edge of the side wall being. The large openings 14 result in interruptions in the Area of these openings. Now becomes a Tersehlußplatte on the side walls 11 flanged, the lost pressure edge of the lower part is replaced by the new pressure edge 6 of the

closing plate 11 are replaced. Fig. 4 shows in enlarged ^ th scale this pressure edge 6. Am opposite the support surface of a side wall seal projecting part 13 of the closure plates 11 causes the pressure edges 6 and the pressure edges 1 to be aligned or in a line.

If a bar 7 is used with two boxes lying next to each other, so this bar in turn has pressure edges, namely 3 and 4 according to the enlarged view! 5 that in turn align with the pressure edges 1 of the lower part.

The bar 7 has arms 5 (see Fig. 7). These arms can encompass the walls 8, 9 of the lower part (see Fig. 1), so that the bar is guided well. However, a positive connection of the bar 7 with the corner parts of the lower part can also be achieved by inwardly deflected tabs 15, in which case corresponding gate projections 8 ', 9 ^{1 are} attached in the side walls 8, 9 of the lower part. The lid Io with its seal then rests on the pressure edges or 3, 4 or 6. The screw connection of the flange plates is known per se when the side wall openings are closed at the top. In the same way, the closure plate according to the innovation is placed on the side walls and screwed to them. As is generally known, the closure plates can be provided with pre-pressings for cable entries.
