Switchgear or switchboard

The invention relates to a switchgear or distribution box comprising a box body and a fastening ring, as well as flexible locking tabs which can be pressed through the mounting opening and made to adhere to the rear surface of the building board.

Known switchgear or switchgear boxes are so designed and installed that they do not allow the switchgear or switchgear boxes to be mounted on pre-paneled walls or are particularly cumbersome to install and require additional fasteners.

The object of the invention is to provide a new type of switchgear or distribution box which enables easy installation of the box on pre-paneled walls or ceilings from the room side.

This object is achieved by a switchgear or switch box according to the invention having the features set forth in claim 1. The dependent claims disclose preferred embodiments of the switchgear or distribution box according to the invention.

In the following, an embodiment of the invention will be described in more detail with reference to the accompanying drawings, in which:

Fig. 2 shows a box body of the device or switch box according to the invention, viewed from above and from two sides, and in perspective views from different directions; Fig. 3 shows a perspective view of the instrument panel or manifold box according to the invention mounted on a building board 11, seen from the inside of a building board 11 and a perspective view of the back panel of a building board 11; and Figure 4 shows a plurality of switchgear or distribution boxes according to the invention on a building board 11 35 mounted in plan view 118582 2 on the inner surface of the building board 11, and in sectional views AA, BB and CC, and in enlarged detail. G.

An exemplary embodiment of the drawings illustrates an instrument box, but the corresponding arrangement of the invention 5 may also be implemented in a manifold.

The enclosure shown comprises a box body 2 (the actual box part) and a separate retaining ring 1. The retaining ring 1 can first be mounted in the mounting opening of the building board 11 from the room side. For this purpose, the fastening ring 1 has elastic locking tabs 3 which can be pressed through the mounting opening and applied to the back surface of the building board 11. The locking tabs 3 are on opposite sides of the mounting ring 1 and are provided with bevelled surfaces 3a which press the locking tabs 3 towards the mounting ring when the mounting ring is pressed into the mounting opening and the bevelled surfaces 3a slide along the edge of the mounting opening. Around the mouth of the mounting ring 15 there are outwardly facing flanges 8 which act as lugs against the inner surface of the building board 11. When the flanges 8 correspond to the inner surface of the building board, the locking tabs 3 click on their own spring force in the locking position. If the sizing is narrow, the locking tabs can be moved to the locking position by hand pressing on the inside of the locking ring 1.

The box body 2 shown in Fig. 2 has strain relief 4 provided with cable: V entry points 5 located in the recesses 5 of the box body 2. These recesses 5 are oriented inwardly from the outside and thereby allow the cable box 2 to be inserted The recesses 5 are bevelled surfaces between the wall and the bottom of the box body (chamfer: about 45 ° and the bottom of the bevelled surfaces have crossed weakening lines or slits 4a between which the claws 4 form a strain relief when the cable is inserted outside the box body.

* * • t · • * · · · · · · · · · · · · · · · · · · · · · · · · · The fastening ring 1 and the box body 2 have fastening elements 6,7 which fasten the box body to the fastening ring when the box body 2 is inserted! into ring 1. Preferably, the fastening members 6,7 are recesses 6 and protrusions 7 in the walls of the fastening ring and the frame body, which snap into each other when the box body 2 is inserted into the fastening ring 1. In this case, also the outwardly facing flanges 9 around the mouth of the box body 35 will be numbered 118582 against the inner surface of the building board 11. Here, the inner surface refers to the room surface of the building board 11 and the opposite surface to the opposite surface remaining inside the wall.

As best shown in Figures 1 and 4, there are connecting members 10, 10a on the outside of the clamping rings 1 for connecting the clamping rings 1 to each other. The connecting members 10, 10a may be implemented, for example, by a salmon tail lift which is connected by displacing the retaining rings axially with respect to one another. The design of the joint 10,10a allows connection between adjacent boxes without the need for a separate connection piece.

10

Inside the wall, the edge of the fastening ring 1 has notches 12 located at recesses 5 provided with a strain relief 4 when the box body 2 is mounted in place on the fastening ring 1. The cables leaving the box body 2 can then be freely directed sideways.

15

To install, follow these steps. First, the retaining ring 1 is inserted into the mounting opening. The cables inside the wall structure are then routed through the retaining ring and the ends of the cables inserted through the strain relief 4 into the box body 2. The box body thus wired is inserted into the retaining ring 1.
