Problems solved by technology

[0003] However, this does not guarantee reliable grounding in any case, because contact openings can occur, for example, due to dust-like pollutants lying between the two or due to existing grooves in the metal profile, which affect the grounding as a whole. reliability
[0004] If the contact plate does not rest completely on the metal profile, corrosion will occur as a consequence, and the contact connection will also be significantly affected by corrosion
[0005] Due to the fact that the contact piece rests only planarly on the metal profile, wherein the contact piece is fastened by means of a fastening screw, there is the danger that the contact piece, in particular during operation of a rail vehicle, preferably using a grounding device, will not The contact piece rotates synchronously with the ground wire subjected to a corresponding pull
In addition, the contact between the contact lug and the metal profile can be broken due to the rotation of the contact lug, which also limits the functional reliability

Embodiment Construction

[0022] The drawing shows a grounding arrangement of a metal profile 1 preferably made of light metal, such as aluminum, wherein the metal profile 1 is in particular a component part of a rail vehicle.

[0023] The grounding device comprises a contact plate 2 which is fastened to the support profile 1 and to which a ground wire 3 is connected.

[0024] According to the invention, the contact plate 2 rests against the metal profile 1 in a form-fitting, non-rotatable manner.

[0025] For the form fit, projections 9 are made in the contact plate 2 by, for example, punching, in particular as figure 2 b) and Figure 4 As shown in d), the bulge is designed to be frusto-conical and protrudes into the outer wall of the metal profile 1 . A gas-tight contact is thus achieved between the contact plate 2 and the metal profile 1 .

[0026] Instead of a frusto-conical configuration of the bead 9 , it can also be shaped conically or pyramidally. A cylindrical shape is also conceivable. ...

Abstract

The invention relates to an earthing device used in metallic material, especially used in the support material (1) with light metals of rail vehicle. It comprises a contact plate (2) fixed on the metallic material (1), a earth coil (3) connected to said contact plate, while said contact plate (2) is anti-rotation adhered on the metallic material (1) to eliminate the breakage of electric contact.

Description

technical field [0001] The invention relates to a grounding device for metal profiles, in particular for support profiles, according to the preamble of claim 1 . Background technique [0002] In the grounding devices used hitherto, the contact plate rests with a flat surface on an associated surface of a support profile made of a light metal, in particular aluminum. [0003] However, this does not guarantee reliable grounding in any case, because contact openings can occur, for example, due to dust-like pollutants lying between the two or due to existing grooves in the metal profile, which affect the grounding as a whole. reliability. [0004] If the contact plate does not rest completely on the metal profile, corrosion can occur as a consequence, and the contact connection is likewise significantly affected by the corrosion. [0005] Due to the fact that the contact piece rests only planarly on the metal profile, wherein the contact piece is fastened by means of a fasteni...
