Low-voltage power rail

The invention relates to a low-voltage busbar with two parallel current conductors that can be tapped via current collectors.

The previously known busbars are all designed so that they meet the strict legal requirements for busbars that are operated below 220 volts. The known constructions are therefore relatively massive and expensive, The current conductors of the known busbars are usually located in a carrier profile, which is either made by itself Insulating material consists of or made of metal and has additional insulation for the current conductors.

Based on this prior art, the invention is based on the object of providing a power rail for low voltage, preferably for 6 or 12 volts, which is easy to set up and inexpensive to manufacture and which gives the impression of being special Conveys ease.

This object is achieved according to the invention in that the current conductors are kept at a distance by end pieces exposed rods are.

The provision of two exposed rods makes it possible to produce a busbar that appears particularly light. the Rods can take on mechanical and electrical functions at the same time and do not require any special supporting structure. as it has always been considered necessary up to now. The exposed ones running parallel to each other Rods also give a particularly interesting, aesthetically satisfactory appearance and allow one very simple pick-up via simply designed pantographs.

In a preferred embodiment, the rods have a tubular cross-section on.

It has proven particularly useful that the rods are round. The provision of pipe cross-sections for the Rods allow a material-saving yet stable construction. Commercially available drawn materials can be used be used. Because of the tube cross-section, practically all common metal materials have sufficient electrical conductor qualities ensured.

It has also proven to be useful that the rods are coated on the outside with plastic and in the coating one in each case, extending to the metal surface, in the longitudinal direction running groove is provided.

The provision of a plastic coating leads to a special one Variety of color design options. This also makes it possible to receive a special remuneration to dispense with the metallic ladder rods.

It has proven to be useful that the current collectors at least partially encompass the rods and are longitudinally displaceable are guided on the bars.

Such a design ensures a particularly stable coupling between the busbar and the current collector.

According to a further feature of the invention, the current collectors grip around the rods in a clamping manner.

Finally, it is also proposed according to the invention that the current collectors are connected to the current collectors via cables attached consumers are connected.

The connection can be attached to or attached to, for example, via magnets. take place in the electrical consumers and / or on or in the pantographs.

A preferred embodiment of the invention is described in detail below with reference to the drawing . Show it:

Low-voltage track with two end pieces and

two pantographs,

attached ball lamp,

Figure 4 - an end view of the first end piece, Figure 5 - a section along plane V-V in Figure 2 through

the parallel bars.

The busbar has a first rod 1 and a second rod 2, which are round in the illustrated embodiment Hollow profiles are formed. The first rod 1 has a longitudinal groove 11, while the second rod 2 has a longitudinal groove 12. An enveloping plastic is shown in dash-dotted lines in FIG be coating 13 indicated, which is interrupted in the area of the longitudinal groove 12 for access to the metal. The plastic coating 13 is not indicated in the first rod 1,

but can also be present there, as with the second rod 2, or it can also be absent.

The first rod 1 and the second rod 2, which are held parallel to one another by the first end piece 3 and the second end piece 2 v / ground, are each encompassed between the end pieces 3 and 4 of current collectors 5, which in the direction of arrows 9, are thus displaceable back and forth in the longitudinal direction of the busbar. The current collectors 8 encompass the two rods 1 and clamping and are non-positively secured due to the clamping effect in each of the shifting positions.

The end pieces 3 and 4 consist of individual parts not shown and are each by means of the connecting screws 6, which penetrate the holes 7, held together.

A transformer 5 with a supply cable 14 is electrically coupled to the second end piece 4. In the transformer 5 is the voltage is stepped down from 220 volts to low voltage, for example 6 or 12 volts.

In the illustrated embodiment according to FIG. Figure 3 is e: η Current collector 8 is connected via a cable 16 to a spherical halogen low-voltage lamp 17. The ball housing is made of metal and can be pivoted in any of the desired positions held in a magnet 10 arranged on the top of the current collector 8.
