Definitions
- the invention relates to a busbar for the power supply of movable electricity consumers with a pantograph that can be moved along the busbar, consisting of a metallic hollow profile with a grinding surface and an essentially U-shaped insulating profile made of plastic which accommodates the hollow profile, the hollow profile being constructed from a deformed metal strip is and on both sides of the grinding surface each has a web arrangement running parallel to the other, which is encompassed by the respectively assigned free end of the insulating profile.
- the two web arrangements each consist of a continuous web which is formed by doubling the metal strip. This duplication of the continuous webs can obviously not be avoided if the metallic hollow profile is to be formed from a single metal strip. For reasons of stability, however, this web doubling is not necessary.
- the known busbars of the type mentioned are characterized by a relatively high cost of materials, which is particularly important when the hollow profile made of an expensive metal, such as. B. copper.
- the invention has for its object to design a busbar of the type mentioned so that it meets all requirements from the technical point of view with the lowest possible material consumption.
- the busbar of the type mentioned is characterized in that the web arrangements each consist of a series of tongues which are formed by cuts in the metal strip and bent out of this.
- the invention is based on the previously unknown knowledge in this context that the web arrangement can also be formed with interruptions from the material of the hollow profile walls delimiting the cavity of the hollow profile. In the end, this leads to considerable material savings without having to accept disadvantages from a technical-functional point of view.
- the arrangement is preferably made such that the tongues of the two web arrangements are arranged at a constant distance. It is advisable to arrange the tongues arranged on both sides of the surface opposite one another.
- the tongues are expediently essentially rectangular. Their dimensions in the longitudinal direction of the busbar can be smaller than the distance between successive tongues. Since the hollow profile is regularly inserted into the insulating profile, it is recommended that the free corners of the tongues be rounded so that this insertion can be carried out without blocking due to hooking.
- the busbar shown in FIGS. 1 and 2 is intended for the power supply of movable power consumers with pantographs that can be moved along the busbar. It essentially consists of a metallic hollow profile 1 with a grinding surface 2 (cf. also FIGS. 3 to 5) and of an essentially U-shaped insulating profile 3 made of plastic which accommodates the hollow profile 1.
- the hollow profile 1 is constructed from a deformed metal strip 4 and has a web arrangement 5 on both sides of the grinding surface 2, which runs parallel to the respective other web arrangement 5.
- the two web arrangements 5 are encompassed by the respectively assigned free end 6 of the insulating profile 3.
- the web arrangements 5 each consist of a series of tongues 7, which are formed by cuts 8 in the metal strip 4 and are pulled out of this (cf. FIG. 6).
- the tongues 7 of the two web arrangements 5 are arranged at a constant distance, the tongues 7 arranged on both sides of the grinding surface 2 being opposite one another.
- the tongues 7 are essentially rectangular. The distance between successive tongues 7 is greater than the width of the tongues 7. In order to avoid jamming and hooking, the free corners 9 of the tongues 7 are rounded on the one hand and the edges 10 of the tongues 7 lying towards the grinding surface 2 are flattened or bent outwards , which is not shown in detail. 1 that the free longitudinal edges 11 of the metal strip 4 face each other on the side of the hollow profile 1 opposite the grinding surface 2.
- the metal strip 4 shown in FIG. 6 is bent upward about those longitudinal axes 12 which are indicated by dashed lines in FIG. at the same time the tongues 7 are bent downwards. Then the hollow profile 1 is inserted into the insulating profile 3, with something in the head area is compressed, which facilitates the insertion and secures the hollow profile 1 after insertion, as it were, in the clamping fit in the insulating profile 3.
