    Description

    BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

    [0031] To further explain the invention, in the figures:

    [0032] FIG. 1 shows a longitudinal section of an exemplary embodiment of a basic form of the connecting line provided according to the invention,

    [0033] FIG. 2 shows a cross section through the exemplary embodiment according to FIG. 1, and

    [0034] FIG. 3 schematically shows an electrical connecting line having two fastening apparatuses at its ends.

    DETAILED DESCRIPTION OF THE INVENTION

    [0035] FIGS. 1 and 2 show an electrical connecting line 1, which is guided as a loop 2 around mutually flush bores 3 and 4 in conductive plates 5 and 6 of a fastening apparatus 7; the fastening apparatus 7 forms an end of the electrical connecting line 1. The loop 2 may for example be positioned between the conductive plates 3 and 4 by way of a crimp connection. The bores 3 and 4 are passed through by a fastening bolt, this not being shown in more detail, by way of which the fastening apparatus 7 is able to be fastened to an electrical arrangement, for example as an earthing line, not shown.

    [0036] Loop ends 8 and 9 of the loop 2 may be connected to a further part of the arrangement, not shown, in various ways, for example by a crimp, press or clamp connection; the loop ends 8 and 9 form another end of the electrical connecting line 1. It should be highlighted that a current, in particular a short-circuit current, flowing through the connecting line 1 flows through both loop ends 8 and 9 to the one fastening apparatus 7.

    [0037] In the exemplary embodiment according to FIG. 3, an electrical connecting line 10 is shown that extends between a fastening apparatus 11 and a further fastening apparatus 12; each of the two fastening apparatuses 11 and 12 is constructed as described with reference to FIGS. 1 and 2.

    [0038] The electrical connecting line 10 is in this case embodied in the manner of a winding having two turns 13 and 14, in which a loop 15 is guided around the one fastening apparatus 11, which loop has its beginning 16 as the (inner) turn 13 in the region of the further fastening apparatus 12. The loop 15 transitions as a further loop 17 in the region of the further fastening apparatus 12 and then runs to the one fastening apparatus 11. This is adjoined by an additional loop 18 here that runs around in the one fastening apparatus 11, so as then to terminate at its end 19 in the further fastening apparatus 12.

    [0039] In other words, the one loop 15 and the additional loop 18, in its bent region, are positioned in the fastening apparatus 11 and/or fastened to the fastening apparatus 11. The further loop 17, in its bent region, is positioned in the further fastening apparatus 12 and/or fastened to the further fastening apparatus 12. One loop end of the further loop 17 adjoins one loop end of the one loop 15 and the other loop end of the further loop 17 adjoins a loop end of the additional loop 18. The loop ends of the two loops are positioned in the further fastening apparatus 12 and/or fastened to the further fastening apparatus 12.

    [0040] In the electrical connecting line 10, the number of turns may be selected depending on the respective loading of the electrical connecting line 10. In the event of loading that is not very high, it may be enough to use just one endless turn in whichwith reference to FIG. 3only one loop 15 is used that is closed by the further loop 17.

    [0041] In the event of higher loading of the electrical connecting line 10, the embodiment according to FIG. 3 comes into effect. In the event of very high loading of the electrical connecting line, additional turns may also be used.
