Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention is explained in greater detail based on the attached figures of the drawing. Here it shows schematically:

(2) FIG. 1 a first embodiment of a grounding device according to the invention in a side view,

(3) FIG. 2 the embodiment according to FIG. 1 in a top view,

(4) FIG. 3 another embodiment of a grounding device according to the invention in a cross-section of a detail, and

(5) FIG. 4 the embodiment of FIG. 3 in an assembled state.

DETAILED DESCRIPTION

(6) FIGS. 1 and 2 show a first embodiment of a grounding device 10 according to the invention. It is essentially produced from a sheet metal, particularly comprising a copper alloy. The base plate 50 shows various connected sections 20, 30, and 40. For example a connection section 20 is provided, which is embodied like a bar and is provided for the crimped connection to electric wiring. Furthermore, a grounding section 30 is provided, which shows a round opening. This round opening can be pushed over a ground 120 at the body of a vehicle such that an assembly of the grounding device 10 to such a ground 120 of the vehicle is possible.

(7) In this embodiment of the grounding device 10 additionally a contact section 40 is provided in an inventive fashion. As discernible from FIGS. 1 and 2, this contact section is produced by way of folding over the material of the grounding device 10. Here, the abutting two ends 44a and 44b of the material folded over are discernible. The folding over has been performed in such a fashion that an interior cavity with an essentially round cross-section has been provided as the interior section 42. This way, the contact section 40 can also be called the embodiment of a cylindrical sleeve area and/or a hollow cylinder.

(8) For producing this dual, particularly symmetric fold preferably a bending mandrel has been placed on the material of the grounding device 10 such that subsequently a folding occurs at both sides about this bending mandrel. Here, the two ends 44a and 44b preferably abut in a contacting fashion.

(9) FIG. 3 shows an assembled situation of a grounding device 10 according to the invention. Here, a grounding device 10 according to the invention was mounted over a ground 120 of a vehicle body with the help of the grounding section 30. A connection section 20 is clearly discernible, which is shown in the un-crimped state. Also easily discernible is the contact section 40, which is here shown with an angle ranging from 0 to 60.

(10) FIG. 4 shows the embodiment of FIG. 3 in the assembled state. Here, the electric wiring 110 is clearly discernible, which now in the crimped state is connected to the connection section 20 of the grounding device 10. At the other end of the electric wiring 110 it is connected to a terminal 102 of the battery 100.

(11) The above-stated explanations of the embodiments describe the present invention only within the scope of examples. Of course, individual features of the embodiments, to the extent technically useful, may be arbitrarily combined with each other without leaving the scope of the present invention.
