"Arrangement of several electrical installation boxes".

The object on which the invention is based is to make the electrical installAEION clear and clear in larger buildings easy and economical to assemble and maintain. This task is particularly important when different electricity, circuits and types of current are available. '

The conventional solution consists in the arrangement of so-called ■ Junction boxes. The required number of junction boxes is j ^; However, too large for larger and more complicated installations and therefore not overly borrowed and uneconomical.

To avoid this, one has already focused on the installation a so-called collective junction box of square Arranged in plan, which contains all the necessary terminals, terminal strips and the other installation parts. This means that all voltages, types of current and circuits can be branched together. !

However, the disadvantage of such a collective junction box is j

in the relatively complicated design, due to the!

Necessity to separate for the individual electricity prices inside:

to arrange te zones. It is necessary to know the individual abbey ^!

to separate the lungs from one another by means of flaps, which are

i kidney need to be attached. The collective junction boxes are. '

also only economical in the main areas of installation.

this gives rise to the need to complete the existing task

more advantageous to solve.

two Q-egen & esa: crossing cables (German patent 332 858). The sockets for the free cable exit and the cable routing are offset from one another and are spaced apart from one another. The cable outlet openings extend towards the center of the box. The offset and spacing is large in this way in relation to the plan area of the can and there is a relatively large space requirement for the overall arrangement of the cans.

In the form of the present invention, a more advantageous solution is proposed. According to its kind, this solution is the Arrangement of several electrical installation boxes, each with Cable outlet openings in the side walls for the cables crossing each other in two levels, with the boxes for the free one The cable outlet and the cable extension are offset from one another and are spaced apart. The distinguishing feature of the invention is that at least one pair of boxes with the well-known quadratic plan is used that different types of current, voltages and electricity prices are distributed on a single box of the pair of boxes, that on each box, the cable outlet openings to the corners of the Squares': · are moved and that the distance dimension and the substitute dimension are essentially limited to the area of the outlet openings

A particular embodiment of the invention is a pair from the installation box on a mountable rectangular plate

attached or attachable, the two long sides and a transverse side of the rectangular plate flush with the box sides ι lie, whereas the other transverse side of the rectangular plate and the distance A protrudes from the box wall.

The gate part of the subject of the invention opposite the h-k-chamm-'lichen Use of a large number of junction or installation boxes is that the installation simplifies, over- is made visible and focused. The pairs of boxes are arranged in the focal points of the installation. If you come i If one pair of boxes is not sufficient, two or more of them can be used.

In contrast to the known collective junction box, the individual box according to the present invention is structurally simple. The separation of the types of current and voltages is absolute. \ clear through the division into at least two individual boxes. ^! In the case of the subject matter of the invention, a better adaptation to the capacity of the installation is possible due to the possibility of adding several pairs of boxes. The single box can also be used for lower capacities. The special storage ^: different box sizes are therefore not required.

Attaching the boxes is particularly easy when using ■ the rectangular plate on which the individual boxes already come with the correct spacing and misalignment on the floor.

The accompanying drawings show various of the possible arrangements and a possible design of a connection box and its installation.

Fig. 1 to 3 are combinations of terminal boxes in a double arrangement or Yier arrangement,

Fig. 4 and 5 show the inner design of a box, Fig. 6 another possible combination, Fig. 7 and 8 show boxes with rectangular panels,

Fig. 9 shows the ceiling installation in a vertical section.

In the arrangement according to Fig. 1, 1 and 2 each two junction boxes of square shape and the same size are designated. The junction boxes are offset by a dimension 7. This creates the on the opposite side walls Free parts 3 and 4. These are for the exit of the cable looms 5 and 6 are provided, each of which runs alongside the side walls of the associated boxes. The amount of dislocation 7 fe is chosen as large as space is required for the cable harnesses will.

A distance A is provided between the opposite side walls of the boxes, so that again between the boxes Cable looms 12 can go through. The crossing cables run on different floors.

Fig. 3 shows the arrangement of four equally sized square junction boxes 13, 14, 15 and 16. They are each around the

same dimension V offset from each other and are at distance A. The distance dimension and the degree of the offset are the same in this Pail measured for three adjacent ovals. A look at the figure shows that this arrangement is very clear.

Fig. 2 shows the boxes in the arrangement according to Fig. 3 perspek- ■ tivisch. At the top of the boxes are either retaining flanges or openings for ceiling mounting. The openings for the entry and exit of the cables are in the office walls. Six openings are grouped together. The groups are each as close as possible to the vertical abutting edges of the side surfaces, i.e. in the area the part of the side wall that becomes free during the displacement. If there are two adjacent side walls, the opening groups are located each on different floors so that the cables can run without crossing. As can be seen in Fig. 2, lie the opening groups 17 and 18 in one side wall as close as possible to the mounting surface, while they are in the other side wall as opening group 19 and 2o so far away from the mounting surface, so that the cables exiting therefrom via the directly cables lying on the mounting surface can run. The individual opening groups each have two one on top of the other Rows of openings of three next to each other, so a total of six openings.

In the arrangement according to Fig. 6, four boxes are staggered, each with a space between the opposite sides of the boxes. This makes it possible

between the boxes further cable strands 45 pass through leave. In the arrangement according to Fig. 6, the required ceiling opening is indicated by a dashed line 44.

In the arrangement according to FIG. 7, two square boxes 51 and 52 of the same size are arranged on a mounting plate 54. The arrangement is made in such a way that distance A and the offset V are maintained between the boxes. In addition, on the left-hand side, the edge of the plate has moved away from the edge of the box by the dimension A. With this arrangement one can the animal arrangement according to FIG. 3 is obtained simply by pushing the two plates against the canted edges 53. At 56 are Designated openings for mounting the plate on the ceiling. 57 and 58 are factory-provided devices on the panels for assembling the boxes. The boxes each also have openings or retaining flanges to accommodate them without such To be able to mount mounting plates directly on the ceiling.

The inner design of the boxes can be seen in Figs. 4 and 5. With 23 and 25 they are from different directions Entering harnesses called. The box has a square housing 21, which with a lid 3o on the maintenance side is lockable. For example, the spring locks designated 31 or other fastening means are used as the lock. Transparent plastic can be used for the lid 3o. This means that the type of current and circuits are immediately available from the outside can recognize, the respective boxes or lids can be labeled ^ a. The openings for the Cable entries can be knockout openings known per se *

With 28 fuses are designated, with 29 a socket for Example for connection to a hand lamp. 26 are terminals. These are with the wires 27 to the lines "or! Line pipes 25 and 23 connected.

The ceiling installation can be seen in section 9. The boxes 63 are mounted directly on the structural ceiling. 6o is a recessed ceiling light. The arrangement is made so that the distance guaranteed access to the boxes between two beams. In the access opening between the two support rails a removable cover part 61 is used. Instead, a built-in light 6o can also be attached to this Place to be provided.

A particular advantage of the subject matter of the invention is its adaptability with regard to the installation conditions. You can combine any number of boxes in one focus of the installation, i.e. as many as at this point in terms of installation are needed. At other locations, for example at locations further away from the center of the building, accordingly, fewer boxes are used. Finally, the single box can also be used where a plurality of boxes is not needed. The boxes can be manufactured uniformly. So it is sufficient to keep a uniform Box. You can use the same box individually, in groups of two, three, or four or in a combination of others larger number. $

The on-site adaptability of the combinations is just as good ο The entire area used by the boxes can

square or any rectangular can be selected. this is particularly important in the case of ceilings that are lowered between girders in view of the need for the boxes accessible through a detachable part. Advantageous is the on-site adaptability of the combination of boxes, but also with regard to the desire under the boxes Arrange lights.

The boxes themselves are simple in their construction, since they are mostly designed for only one circuit, one voltage or one type of current need to be. No special safety precautions are necessary for the division into different zones. So the boxes are relatively low in the Bauari? One is with regard to the on-site design, especially in Relation to the lowering dimension of the ceiling, not tied to the dimensions of the box.
