etromsGhiönen - Aiibrdniuig for small conductor rails

Grinding lines of lifting equipment, mobile Bearbeitüngseinrichtüngen, bewe _o union Beleuchtungaappaiaturen and busbars are deigl t know, with as used maäsivin iCöpf s so that they can be used even with considerable wear long time ", eg having also developed dumbbell-shaped profiles for this purpose, ie rails with two through a »footbridge connected to each other. After the wear of a rail head, the rail is turned through 180 about the longitudinal axis ^Q, so daii now the other Soiiienenkopf the dienfc.

Such profiled otromsöiiien are also used for so-called small-ocjileiflinien. These are approved for the purchase of only low electrical power and are used, for example, for leashes, decrements, and the like. used. 2 ^{1 For} two-part 3-part power rails, it is advisable to arrange the rail head running through it so that it can be removed from a continuous holding rail that is bent from sheet metal strips. The rail head is pulled up or clamped on; if necessary, it is made of a different material than the retaining rails. The known busbars are relatively expensive and heavy. 909833/04 9 9 ORIGINAL BATHROOM

The invention is based on the object | the attachment considerable, to cheaper uad at the same time the Sin and To simplify expansion of the otromsohienen.

To achieve this object arrangement busbar at Klain-dchieifleitungen proposes one-piece ätromsciiienen erfindungagemäö for a _t the busbars siua to form a sheet metal profile which at right angles to the contact side of the ätromabnehmer an approximately planar contact surface and thereto, or nearly perpendicular abuttingly two mutually rectified webs possesses, the turns facing each other, end in flanges facing away from the outside, and the insulation pads to accommodate this jilanache in brackets; to train.

Jie new training exhibits a unified body both for the .tie contact surface bearing, i.e. for current consumption serving ieil, al3 also for the una to hold the part. This uniform body is extraordinarily simple because it comes from a strip of laughing can be shaped. This can e.g. done by a kind of die-roll process in which the sheet metal strip successively passes through several reels that gradually make it bring in the desired shape. If necessary, you can also achieve the shape by folding. The deformation can take place cold. '

The Eontaktflache has no greater sheet thickness than that remaining! parts. This design is based on the knowledge that with the building materials available for the Pantograph the wear so largely relocated to the pantograph itself and thus kept away from the busbars can be that a replacement of the busbars - if at all - only at very long intervals is required.

The formation of two resilient open bends on the underside of the conductor line has the advantage that the fastening can be made resilient, so that both the installation and the removal of the power line are very simplified. In addition, the elastic fastening compensates for any small unevenness in the base and inaccuracies in the assembly, thus avoiding reworking and corrections on the spot and reducing the demands on precision.

The insulation pad can attack these open bends. It is expediently designed like a bracket, so that it embraces the branches mentioned elastically but still firmly from the outside.

* "" The flanges and bends make the moment of inertia ^ of the rail profile compared to the well-known V- and U-Profi ~

leii of busbars with the same height and the same in both bending planes considerably 'enlarged. In order to

the rigidity of the busbar is greatly increased, so that fewer layers of insulation per length required are and also improves the running properties of the pantograph will.

The branches are not just for attaching to the Isolators advantageous, they also shake the possibility of φ to attach the power supply in a particularly simple manner by means of a clip-like connector. This plug connection then includes the bends and flanges mentioned.

This has the further advantage that no screws or nuts or other movable and easily lost, possibly also corrosive over time or from other Reasons no longer need common connecting parts ^, but that the busbars, insulation pads and the power connection by simple resilient clamping without further aids can be quickly connected to one another, even by laypeople.

Some exemplary embodiments of the invention corresponding to this basic concept are shown in the drawing, and FIG although shows:

Pig. 1 "a cross-section of the small conductor rail, FIG. 2 shows the cross section of a busbar and FIG. 3 shows a plug for the power supply.
