Definitions

  • the invention relates to a device for contacting a workpiece with the features of the preamble of the claim 1.
  • Such devices are used, for example, in the automotive industry used the chassis ground with the negative pole to connect the battery electrically.
  • bolts welded on which can be attached to a cable lug and a cable with the negative pole of the battery electrically conductive are connected.
  • a ground bolt for Attaching a cable lug disclosed that one to a workpiece weldable bottom part and an adjoining one Has thread area.
  • the bottom part formed as a hexagon, so that over a Arrangeable plastic part with hexagon socket and cutouts for a cable lug this is secured against rotation by means of a Screw can be attached.
  • the present invention is therefore based on the object a simple, inexpensive and non-rotating device to create a workpiece.
  • a cable lug with a non-circular inner circumference can be postponed.
  • the one adjoining the collar in the direction of a welding tip Flange is not only used in the invention as Stop for a cable lug that can be pushed onto the collar, but also the contacting.
  • This can in the invention advantageously both over the end faces of the electrically conductive cap nut with one side of the cable lug (the so that it is connected to the bolt via the thread), over the inner peripheral surface of the cable lug, which with the Outer surface of the collar comes into contact, and through which the Cable lug facing flange face with the other side of the cable lug.
  • Another advantage of the invention is the fact that because of a plastic part that is no longer required, the entire Connection consists of a material, namely metal, and the connection is no longer disconnected during recycling / disposal (in plastic and metal) disposed of or recycled must become.
  • the flange can according to the invention as a circumferential flange be formed, it also being rotationally symmetrical May have outer circumference.
  • the circumferential flange the same outer diameter as the cap nut or towers over it.
  • the facing each other Surfaces in one plane for example perpendicular to Longitudinal axis of the device lie, so that advantageously not only a circumferential ring line but also an optimal one large ring area as contact area between the cap nut face and the flange side facing her is created.
  • the collar has Outer circumference edges on. These can be straight or curved Pages are connected.
  • the collar is on the outer circumference as a polygon, for example as a hexagon or octagon, executed.
  • a polygon can be used Inner circumference of the cable lug not only in a simple way, for example, by stamping, but also in various positions on the collar polygon against rotation to be ordered.
  • the collar bolt 1 shown in Fig. 1 has on its one end of a welding tip 3, which is cylindrical can be formed and at its other end a threaded area 5 with external thread 7.
  • the thread area 5 is with the welding tip 3 over a collar 9 and one adjoining flange 11 coaxially connected or made from a piece having a common longitudinal axis.
  • the stepped in relation to the threaded area 5 in the outer circumference Extended collar 9 is a hexagon with straight Side surfaces trained. At this collar 9 closes Compared to the collar 9 in the outer circumference expanded stepwise circumferential flange 11, which has a circular outer circumference owns.
  • FIG. 3 a cap nut 13 shown in FIG. 2 as an individual part screwed end on the thread area side.
  • This Cap nut 13 like conventional cap nuts, has a bowl-shaped one Head area 15, to which a central area 17 with Internal thread 19 connects.
  • Cap nuts have the cap nut 13 according to the invention in the direction their opening extended beyond the internal thread 19 Area 21, which is opposite the inner circumference of the Middle region 17 a step-widened inner circumference 23 owns.
  • step-like subdivision includes the outer circumference of the end region 21 in the Outer periphery tapered outer peripheral region 25 of the central area 17.
  • This conical outer circumference 25 of the central region 17 is at the transition to the head region 15 the central region 17 on the outer circumference as a in FIG. 2 and FIG. 3 external polygon, not shown, for example Hexagon or square, trained. This polygon serves like with conventional cap nuts the attachment of a wrench or a must to screw the cap nut on and off 13.
  • the combination of the collar pin 1 shown in FIG. 3 with a fully screwed cap nut 13 illustrates the Interaction of both parts.
  • the cap nut 13 stands with the Thread area 5 of the collar bolt 1 over the in the external thread 7 engaging internal threads 19 in contact, whereas in the head area 15 between the inner circumference of the head area 15 and the outer circumference of the threaded area 5 of the collar bolt 1 a free space is formed.
  • the end region 21 of the cap nut 13 on the inner circumference does not touch the outer circumference of the collar 9 of the bolt 1, so that here too between the collar and the inside of the End area 21, a free space is formed.
  • this freedom can the cap nut 13 of the invention without tilting the End region 21 with the collar 9 screwed onto the bolt 1 become.
  • the cap nut 13 comes with at least part of it End face with the side of the flange 11 facing it in Contact.
  • the end face and the flange side facing her lies in one plane, so that an optimal large contact area is created.
  • this level is the contacting surfaces perpendicular to the longitudinal axis of the entire Device because the face of the cap nut 13 is just as straight is completed, like the side of the flange facing her 11.
  • a welding of the collar bolt 1 with its welding tip 3 to a carrier, not shown in the drawing, for example a body part in the engine compartment, can be without or done with screwed cap nut.
  • An advantageous one for this screwed cap nut, which also the welding current transferred to the collar stud and to the welding tip can reduce any contamination during the welding process the contact areas for the person to be recorded later the drawing cable lug, not shown.
  • the threaded area 5 or threaded shaft but also the end face of the cap nut 13 facing her Protective flange side and outer surface of the collar 9 covered.
  • a cap nut 13 or already screwed on during welding cap nut 13 screwed on later further prevents any Contamination in the automotive industry necessary painting of the engine compartment and any contamination can arise from storage.
  • the cover can even have a sealing effect, so that even with immersion of the contact surfaces or oxidation during storage can be prevented.
  • the contacts of a collar bolt welded to a carrier 1 is then done by sliding on a cable lug with, for example, the hexagon of the collar 9 accordingly trained hexagon or square, etc., and by unscrewing the cap nut 13 until the cable lug the end face of the cap nut 13 from one side and the side of the flange facing him from his other side is applied with a force.
  • the invention results in one in the drawing Contacting, not shown, compared to the state of the Technology a significantly improved contacting of a cable lug, since with known non-rotating ground contacts a cable lug only from one side over the side facing it Front side of a mother is contacted, which over the thread is connected to the bolt.
