- the inner recess 20 has a peripheral wall 30 which inclined by about 10 ° relative to the axis 31 of the cover is.
- the inner recess 20 has a depth 32, the is sufficient to a chamber 33 inside the lid 2 limit.
- the chamber is designed so that they have a the largest possible amount of material during the drawing process the cylindrical sleeve 1 is displaced, can accommodate.
- the cylindrical sleeve 1 consists of electrically conductive Material, e.g. made of electrolytic copper.
- the lid 2 is made of an electrically conductive material manufactured having mechanical features that are sufficient to the pressure forces occurring during to record the drawing process.
- the lid 2 in an advantageous manner a copper alloy, e.g. Copper that with Beryllium, strontium, zirconium, nickel-silicon alloyed has been.
- a copper alloy e.g. Copper that with Beryllium, strontium, zirconium, nickel-silicon alloyed has been.
- cylindrical sleeve 1 and the lid 2 made using a material that has the same thermal expansion coefficient.
- cylindrical sleeve 1 and the cover of the second be coated with a tin layer.
- the providence of a tin layer prevents one unwanted oxidation process on parts of the electrical Contact.
- the first step in the process is to daS the web 40 of the rail body with a continuous Bore is provided. It is envisaged that the Diameter of the drilling tool slightly larger than the Dimensions 25 of the circumferential shell 26 of the cylindrical Sleeve 3 is.
- This caliber has a decent design and is together with the mounting device, not shown delivered.
- the calibrated head 7 of the drawing tool is in the Through hole 102 of the cylindrical sleeve 1 of the Side of the abutment flange 4 used.
- An extension of the calibrated head of the drawing tool 7 occurs after insertion into the through bore 102 of the sleeve 1 on the side opposite the bottle 4 side of the sleeve this one off.
- the inner recess 20 of the lid 2 is on the web 40 of the rail body directed (arrow 42).
- the cover 2 is in abutment with the web 40 of the Rail body held.
- the conical section 43 of Pulling head 7 brings during the expansion pulling the Sleeve 1 derenn outer jacket 26 in non-positive Connection with the wall of the bore 28, creating a excellent, lasting, electrical contact created becomes.
- the figure 6 can be seen that in an advantageous Way, using an electrical contact, one Arrangement on webs of rail bodies with different Thickness 100, 101 is possible.
- the figure 7 and 8 can be taken as two electrical Ladder 50 with its connection shoes 51 on both sides of the Rail body 52 footbridge 40, using a single sleeve 1, to be mounted.
- both cable lugs are under Use a single screw 55 mounted and fixed braced.
