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

The earthing device that is used for shape
Technical field
The present invention relates to a kind ofly be used for the earthing device that shape is used in particular for support sections by claim 1 is as described in the preamble.
Background technology
In employed earthing device up to now, contact plate is close to by a kind of light metal particularly on the face that sets of the support sections made of aluminium with a flat face.
But do not guarantee under any circumstance all ground connection reliably at this, because for example owing to be positioned at the pollutant etc. of grit shape between the two or because the groove that exists on the shape can produce the contact and disconnect, it influences the reliability of ground connection on the whole.
In a single day consequence that contact plate not exclusively abuts on the shape is corrosion to occur, and contacting is same owing to corrosion is subjected to influencing significantly.
By contact chip only plane earth abut on the shape, wherein this contact chip is fixed by means of a fastening bolt, there is such danger, promptly particularly because contact chip in service at the preferred rail vehicle that uses an earthing device, with the situation of the ground line locking that suffers corresponding pulling force under, described contact chip rotates.In addition, contact between contact chip and shape can since the rotation of contact chip disconnect, thereby also limitation function reliability.
Summary of the invention
The objective of the invention is to, develop such earthing device further, make and improve functional reliability by the simplest device on the structure.
This purpose realizes by the earthing device with claim 1 feature.
Guarantee that by this structural configurations contact plate is close on the shape enduringly and all the time contacting.Eliminating the contact thus disconnects.
According to favourable expansion structure regulation of the present invention, described contact plate has the projection of preferred conical or pyramid in the zone of the contact-making surface of itself and shape shaped structure, this shaped structure is pressed in this shape when fixing to clamp with shape and realizes airtight contacting simultaneously, by the corrosion of this contact preventing shape.
But also can consider the shape of the bulge-structure that other and described shape respective recess adapt in principle.
Except the contacting in the contact area of tenon and shape, in addition with in the zone of the bearing-surface of shape linear at least contacting appears also at contact plate after the fixing to clamp of contact plate.
Described tenon that is bulge-structure are made especially simply by punching press, wherein so a kind of decompressor by a suitable mould for example a forging die and a corresponding pin as formpiston as die make.
Particularly it highly so selects the size of tenon, makes described tenon be pressed into without difficulty in the contact-making surface of shape.
The fixing of contact plate can be by the preferably T-slot fixture block realization of groove fixture block, and this groove fixture block is guided in the cannelure of shape and is close on the inwall of the shape that constitutes hollow profile with clamping.
This contact plate is bearing on the shape anti-rotationly, so that the accurate location of contact plate is provided with each backstop salient point on contact plate for this reason, described backstop salient point is close on the wall of cannelure.These backstop salient points can be made by punching press equally.Self-evidently be, also can consider other shape of backstop, described backstop extend in the cannelure of shape and is close on the opposed wall.
Other favourable structure of the present invention shows in the dependent claims.
Description of drawings
Below by means of the description of drawings embodiments of the invention.In the accompanying drawing:
Fig. 1 illustrates one embodiment of the invention with different views;
Fig. 2 illustrates details by Fig. 1 embodiment with different views equally;
Fig. 3 illustrates an alternative embodiment of the invention with different views;
Fig. 4 illustrates details by Fig. 3 embodiment with different views equally.
Embodiment
The earthing device of a kind of shape of preferably making by light metal such as aluminium 1 shown in the drawings, wherein shape 1 part of rail vehicle particularly.
Earthing device comprises a contact plate 2, and this contact plate is fixed on the support sections 1 and connects a ground wire 3 on this contact plate.
By the present invention, contact plate 2 shapes are close on the shape 1 sealedly anti-rotationly.
For shape is sealed, in contact plate 2, make each lug boss 9 by for example punching press, especially as Fig. 2 b) and Fig. 4 d) shown in, described lug boss is designed to lug boss truncated cone shape and described and extend in the outer wall of shape 1.Therefore realize a kind of airtight contact between contact plate 2 and shape 1.
Replace the structure of the truncated cone shape of lug boss 9, described lug boss also can be configured as circular cone or pyramid most advanced and sophisticatedly.Also be contemplated that columniform moulding.
Described contact plate 2 is connected with shape 1 by clamping device, and a T-slot fixture block (Nutstein) 5 is set for this reason, screws in a screw 6 in this groove fixture block 5, and this screw passes contact plate 2 and this head of screw is pressed on the pad 7.
T-slot fixture block 5 is guided in the cannelure 4 of shape 1, and on the wall that define cannelure 4 of medial support at shape 1.
In order to realize the anti-rotation of contact plate 2, this contact plate has backstop salient point (Anschlagwarzen) 8, and per two backstop salient points wherein are close on the wall of cannelure 4.Backstop salient point 8 can be made by punching press equally.
The height of lug boss 9 designs in this wise, makes described lug boss can be pressed into without difficulty in the shape 1, and contact plate 2 plane earths are close on the face that sets of shape 1 subsequently.
The size of groove fixture block 5 is determined in this wise, make it on the use location, rabbet the wall of (hintergreifen) shape 1, but in order to insert, the groove fixture block on its width less than the width of cannelure 4, thereby the groove fixture block can be inserted into the cannelure 4 from top, and only half-twist so that fixing.
In the embodiment shown in Fig. 1 and Fig. 2, contact plate 2 is designed to flat plate.And described contact plate is designed to angled shape in Fig. 3, connects ground wire 3 thereby extend ground perpendicular to the bearing-surface of shape 1 here.
Can find out in a) at Fig. 1 the end view of earthing device b) to be vertical view, c) be perspective view.
Fig. 2 illustrates the contact plate 2 as single-piece, a) is end view, b) be by figure a) in along the partial sectional view of A-A line, Fig. 2 c) be the vertical view of contact plate 2, d) be end view, e) be c) in along the sectional view of B-B line, f) be perspective view.
At Fig. 3 a) to 3c) and Fig. 4 a) to 4e) in embodiment be comparable.
