1 shows a device system, which consists of three device modules 10 exists on the DIN rail designed as a DIN rail 20 are mounted.

In the mounting rail 20 is the PCB serving as bus line 30 used and in this with support elements 32 held. For the supply or continuation of bus signals are at the two ends of the circuit board 30 Connection elements, eg pin headers 31 , intended. In such pin headers, for example, plug connectors designed as socket strips can be used.

Details of the inventively designed, usable in the carrier rail bus line are from the 2 to 5 seen.

So shows 2 a mounting rail 20 into which the circuit board 30 with five tracks 33 is used. The circuit board 30 is in the mounting rail 20 arranged at ten evenly spaced th carrier elements 32 established.

3a and 3b do not leave them in the mounting rail 20 mounted circuit board 30 with the carrier elements 32 recognize from above and below. To the carrier elements 32 regarding the circuit board 30 These are with PCB pickup pins 32a equipped, which in these appropriate recordings of the circuit board 30 intervention.

The soffit according to 3b illustrates that even the lower PCB surface 34 for additional interconnects or crossings and for contacting terminal, pin or socket strips is usable.

Details of the circuit board 30 carrying carrier elements 32 are more accurate in the 4a and 4b shown.

The the circuit board 30 carrying center bar 32 is, as already mentioned, with upstanding spigot 32a fitted, which engage in recesses of the circuit board and fix it with it. To lock the carrier element in the mounting rail are laterally on the central web 32d elastic spring snap noses 32b provided, which snap on the mounting rail edge. Further recognizable is a coding nose 32c , which intended in a provided on the device housing recess 10a intervenes. This coding nose ensures the correct positioning of the device 10 and thus the correct contact of the in 6 illustrated contact springs 11a ,

The correct positioning of the contact springs 11a is especially with broken tracks 33 significant.

With the 5a and 5b , Which show the mounting rail with circuit board in a perspective view, on the one hand, the definition of the circuit board in the support rail 20 by means of the carrier elements 32 illustrated again and on the other hand, the possibility of separation of the tracks 33 shown.

A stable but detachable position assurance of the printed circuit board 30 within the mounting rail 20 This ensures that on the one hand, the PCB receiving pin 32a Holes of the circuit board 30 enforce and on the other the snap noses 32b laterally grasp the mounting rail edge.

As especially the enlarged representation in 5b makes clear, are in the area A, the interconnects in interconnect parts 33a and 33b separated, so that between these conductor track pieces 33a and 33b an insulating space 33c is formed.

Such a design is necessary if a separate supply or extraction of bus signals is desired. For this purpose, at this point is an electrical device 10 with an in 6 illustrated contact block 11 necessary. This contact block 11 has two contact springs 11a of which the one contact spring on the conductor track section 33a and the other on the conductor section 33b rests.

The in 6 shown section shows an expedient design of the electrical device for the illustrated application.

The contact springs 11a of the contact block 11 enforce the bottom of the electrical device 10 and lie contact-forming on the conductor tracks of the circuit board 30 on. Inside the device 10 is the contact block 11 on a circuit board 12 attached, via which the further wiring of the device takes place.

Especially in the case of separate decoupling or feeding of bus signals into or out of the device module 10 it comes down to an exact positioning of the device 10 in relation to the circuit board 30 at.

To ensure this, is the side housing wall 13 of the device 10 with a recess 10a provided, in which the coding nose 32c of the carrier element 32 intervenes.

Based on 7a to 10b is a second embodiment of the carrier element 52 explained with its possible application.

As especially the 7a and 7b let recognize this support element is different 52 from the carrier element 32 in that at the middlebridge 52d a locking bar 52e about a movie hinge 52f is articulated. Also this support element 52 has snap noses on both sides 52b on which intended on the laterally projecting flanges 20b the mounting rail 20 be snapped up. Further, on the central pier 52d PCB spigot 52a provided, which are not shown recordings of the circuit board 50 assigned.

The carrier elements 52 be in the same way as the carrier elements 32 with the circuit board 50 connected. This is the circuit board 50 on the Mittelstege 52d the support elements 52 put on, the PCB pick-up pin 52a intervene in the appropriate recordings.

8a shows one with multiple support elements 52 preassembled BUS circuit board 50 in bottom view and leaves the PCB surface 54 so as for the correct position mounting of the device modules 40 required Codierbohrungen 51 detect.

After the pre-assembly, the over the film hinges 52f with the Mittelstegen 52d connected locking webs 52e pivoted by 180 °, so they, like 8b shows, on the surface of the circuit board 50 rest. In this position engage under the free end of the Arretierungsstege 52e provided snaps 52c one at the in the 7a and 7b right at the snap nose 52b provided, inwardly before jumping latching web 52g , This snap connection can by lifting the Arretierungssteges 52e by means of the actuating nose 52h be manually released again.

By means of the carrier elements 52 can be the bus circuit board 50 fully embrace it as a unitary assembly, as in 8b is shown on the mounting rail 20 Can be snapped up, like this with the 9a and 9b is illustrated. At the same time, the enclosure of the circuit board 50 increases the stability of the overall arrangement.

The distance between two adjacent carrier elements 52 is sized so that between each one device module 40 Has space, as with the 10a and 10b is illustrated. The between adjacent device modules 40 located support elements 52 provide for a mounting distance 42 between these. This mounting distance ensures a much better heat dissipation, since a free convection can form between the individual devices, whereby the supply of cooling air is ensured.

However, if such a mounting distance is not desired because of a larger space requirement, device modules are to be used, which in the lateral bottom area the dimensions of the locking webs 52e have corresponding recesses, so that when mounting the device modules engage over the locking webs and the housing of the device modules are adjacent to each other.

The main advantage of using the 9 to 10 illustrated arrangement is that for the PCB bus 50 Any, on the mounting rail 20 mountable module housing used without lateral geometry adjustment who can. The condition is that the housing of the device module 40 a housing bottom opening 40a through which the contact springs 41b within the device module 40 located contact block 41 protrude so that they after mounting the tracks 50a the BUS circuit board 50 to contact.

The position assurance and coding of the device modules 40 serves one at the contact block 41 integrally molded coding pin 41a , which when mounting in the appropriate PCB hole 51 dips.

While at the in 8b and 10a and 10b shown design of the circuit board 50 continuous tracks 50a are provided, they are in accordance with the execution 9a and 9b interrupted so that between the tracks 53 ' a gap 53a is formed, which is an interruption of the tracks 53 ' represents. By this measure, as above with reference to 5a and 5b explains, a separate supply or decoupling of BUS signals possible.
