Power distribution system with; Frofile rails

The invention relates to a power distribution system with U-shaped profiled power take-off rails, which have current conductors held in insulating bodies and the between
Detachable adapters for power consumption on both legs with a latching action, especially for lighting purposes!

A power distribution system of the type mentioned above is nice known from DT-OS 23 36

The well-known power distribution system uses power sewing rails » those with distribution boxes: are connected. In the two Electricity nancies providing electricity can be used with Lamps rigidly connected adapters are introduced by a complicated mechanism in the power take-off rail being held.

This Stromverteilungssystera is - especially by the Use of the voluminous distribution boxes - bulky and affects the visual-aesthetic impression of the room, if the ceiling is not suspended - as suggested in the above-mentioned publication.

The invention is based on the object of a power distribution system specify the type mentioned above, which can be easily installed and handled and expanded Application possibilities offers.

This is achieved according to the invention in that an insulating body for receiving in each current draw bar at least three current conductors is provided, the current conductors first and second, if necessary, independently belong to each other switchable circuits that the adapter has a contact guide body, its through Spring-loaded contact pins depending on whether the adapter is rotated 18o degrees around its longitudinal axis in the power take-off rail is used or not, take the current from the conductors of the first or second circuits.

This has the advantage that the same current draw is used different consumers can be switched on and off separately.

A further development of the invention is that the adapter is provided with latching in the current draw rail retaining springs whose extended ends at two opposite nachgibig resiliently formed surfaces of a cover terminate the adapter, wherein compressed by pressing on the faces of the Ealtefedern and thus the Release latch.

This has the advantage that the adapter can be inserted and removed with one hand.

Another development of the invention is that the preloaded springs that the contact pins against the Press current conductors, are arranged coaxially zu.den contact pins.

This has the further advantage that the vogespensioned Springs create a release force that makes it easier to remove the adapter.

The invention is explained in more detail using the exemplary embodiment shown in the accompanying drawings. Show it:

An adapter 2 can be used in the power take-off rail 1 in order to ensure the power supply for any consumer; For example, for the lamp 3 shown in FIG. 1, which is held by the adapter 2 by a support bracket k. The power take-off rail 1 made of aluminum has a profile that forms two spaces l ^f and 1 ″, as shown in FIG

evident. The space 1 'takes an extruded insulating body 5 made of PVC, in the copper conductor 7 are anchored. Cables for special purposes, but especially for power supply the power take-off rail can be accommodated in room 1 ".

The power take-off rail 1 can be attached to a lengthing device 8 can be hung or installed as a ceiling device socket. The power take-off rail 1 can also be laid under plaster will.

A single locking screw 9 must be actuated to move the power take-off bar 1 up into the suspension device 8 use, it is not necessary to insert the power take-off bar 1 from the end to it in the desired position.

With regard to the length of the power take-off rail 1, there is no limit, since these are attached to one another piece by piece can, wherein the conductors 7 are continuous or are connected to one another by intermediate clamps.

The three conductors 7 are side by side, with the center conductor is the phase conductor and the side conductors are the neutral conductor of two separate circuits.

The adapter 2 contains a cover 10 with knobs 11 and II 'on two resilient parts, which are formed by slots in two opposing walls in the cover 10. The contact guide body 12 is attached to the top of the hood 10, the cover 13 of which is fastened to the hood 10 ^{by self-tapping threaded screws I 1 I.} Two contact pins 15 slide in the contact guide body 12

offset next to each other and embedded facing in the same direction. They are pretensioned by compression springs 16. in the Contact guide body also contains a ground screw 17, which is connected to the earth contact spring l8.

The two contact pins 15 and the grounding screw 17 are connected to the connections 20 with the wires 19 of the feeder cable 21 connected, which is guided in the grommet 22 through the lower part of the cover 10 and by a cable clamp 23 is strain relieved.

The retaining spring 2h enables the adapter 2 to be inserted into the power take-off rail 1, whereby the earth contact spring l8 is connected to the power take-off rail 1, and the contact pins 15 produce good electrical contact with the copper conductors 7 under the presaporation effect of the compression springs 16.

To remove the adapter 2 from the power take-off rail 1, all that is needed is pressure on the knobs 11 and 11 ', whereby the retaining spring 2k releases the adapter 2 to engage. The pretensioned compression springs 16 generate a disengaging force from the contact pins 15 on the power take-off rail 1, which accelerates the removal.

Thanks to the copper conductors 7 arranged next to one another in the power take-off rail 1 and the arrangement of the contact pin and the earth contact 17 in the adapter 2, it is possible to insert the adapter 180 ° around its longitudinal axis into the power take-off rail, so that two circuits that can be switched independently of one another are used can. This solution provides advanced applications, for example, that one of the two circuits of the emergency lighting is used at night.
