'' Distribution box for electrical installation devices "

The invention relates to a junction box for receiving electrical installation devices ₀ to the requirements of modern installation includes installation distributions ,, whose sizes can be varied at will "

There have been known distribution box ^ which are assembled from numerous components by costly screw or rivet connections ₀ The distributions are my in general · provided with covers ^ which are fixed by expensive ,, according to the provisions sealable screws on the distributions ,,

There are also junction boxes made up of standard components known. The German patent specification 901 contains a junction or distribution box that can be made from standard components in various sizes. One of the things here is that screws and nuts are necessary to join the individual parts together Making production more expensive and making assembly more difficult "Likewise, patent specification 1 180 816 deals with a box made of insulating material for electrical devices, which is assembled in a modular manner from a number of base and cover parts and detachably connected to one another."

The invention is based on the object of avoiding the known bad parts, in particular a junction box create, the size of which can be varied as desired, paying particular attention to cost savings and easy assembly will. To solve this problem, the invention is based on a distribution box with a device support rail and cover plate Recording of electrical installation devices. .The invention consists in that on the outer surfaces of the distribution box Devices for locking several boxes together and devices for locking the device support rail on the inner surfaces and the cover plate are arranged »

The invention allows distribution boxes of any size by simply locking several distribution boxes according to the invention can be made without screws. This enables distribution fields to be put together in the various DIN sizes.

In an advantageous development of the invention, the devices to be 'latching profile rails, press pins, barbed pins, wedges or the like «The latches of the Cover plate can have tabs or recesses that are transplanted after the cover plate has been placed on, it is not necessary so expensive sealing screws or nuts.

Two examples of the firing are shown in the drawing shown »It shows:

a distribution box with cover plate ι the locking of the cover plate with the distributor; the lateral latching on the distributors for Connect two or more distributions too a unit;

the attachment of the full conductor in the distributor; the locking of the device support rail in the distributor; a further design for connecting two or more distribution boxes to form a unit; 7 shows a further embodiment for locking the device support rail in the distributor,,

A distribution box 1 with latches 2 for the assembly of device mounting rails in two levels is shown in Fig. ₀ I ₀ At the four corners within the distribution board there is wiring 3 for attaching the cover plate 4 by barbed bolts 5 (Hg ₀ 2) ₀ the cover plate is provided with device cutouts β <> The cover plate is sealed on the tabs 7 of the distribution box and the cover plate ₀ nen ₀ The holder 10 is used to attach the neutral conductor or the lower conductor rail 18 ₀

To loosen the cover plate 4 (Figo 2) a tool ^ ZaBo screwdriver inserted into the opening 11 and turned until its flanks rest on the sides 12 of the opening 11 and thus the latch 5 from the latching 3 Lift off o The cover plate can be passed through with a sealing wire Recesses 13 are sealed in the tab 7,

In Fig. 3 the side walls of two distributors are shown. The wedges 8 of the distributor "a" are inserted into the grooves 14 of the distributor "b" from above, while at the same time the wedges 8 of the distributor ".b" from below into the grooves 15 of the distributor "a" are introduced and the distribution "a" is pushed up to the stops 16 on the distribution "b" »In the stop position, the locks 9 lock with recesses. 19 pushed into the opening 2O ₉ 20a of the holder 10 and held in., The recess 21 «,

Another latching option of a device support rail is shown in Figo 5. The rail is inserted into the angle of the latching 2 (Figo 1) and locked over the wedge surface the latching edge 27 is pressed on ₀

In Pig «6 there is a further implementation possibility for ver · = "bind two or more manifolds to form a unit by means of profiles 28 that fit into the grooves 29 of the Distributions are inserted. The grooves and profile are preferably designed in a light adhesive »

A third embodiment for fastening the device support _{rail is shown in Mg 0} 7 °. The rail 30 is locked into the recess in the side wall 32
