Definitions

  • the invention relates to a crimped roof-shaped connecting disk of non-circular outer contour for clamping electrical connecting conductors to a device-fixed connecting piece by a screw penetrating an opening in the connecting disk and releasably held on the connecting piece, against which the connecting disk can be tilted to compensate for different conductor diameters, with transverse from opposite edges to the roof ridge inwards at a distance from the opening extending clamping beads arranged on the underside of the pane.
  • connecting conductors with different cross sections of 1 to 2.5 mm2 could be clamped with a connecting washer for screws of 3.5 mm. With smaller cross-sections, secure clamping was no longer possible.
  • the present invention is therefore based on the object of creating a simple connecting disk with which it is possible to securely clamp smaller conductor diameters compared to the known connecting disk.
  • the characteristics in relation to the clamping beads are crowned in the direction of the ridge of the roof, the depth of the crown being adapted to the smallest conductor cross section.
  • the thread passage is designed to be almost sharp-edged without a feed radius.
  • a simple method for producing the connecting disk has been found to be that an oval punched-out opening is formed from the smooth connecting disk to form the stampings and then the roof is stamped, a circular opening then being formed from the oval punched-out hole.
  • a connecting disc 4 On an electrical device with parts made of insulating material is between boundary walls 1 on a connector 2 made of metal by a screw 3, a connecting disc 4 is releasably held.
  • the connecting disk 4 is angled roof-shaped and provided with a centrally provided opening 5 for the screw 3. Outside the opening 5, 4 clamping beads 6 are provided on the side of the connecting disk facing away from the roof, which extend transversely to the ridge direction of the roof inwards. Expressions 7 are pressed between these clamping beads 6, which adjoin the opening 5 and thus come as close as possible to the screw 3 in order to be able to clamp the connecting conductor 8 with a small diameter, as shown in FIG. 1, in a satisfactory manner.
  • the features 7 are wider in relation to the clamping beads 6 in the roof ridge direction and shorter transversely thereto.
  • the thread passage in the connecting piece 2 is on the side facing the connecting conductor 8 without a draw-in radius, so that the clamping space can extend as far as the thread of the screw 3.
  • the connecting disk 4 is provided as a smooth disk with an oval punched-out area to form the opening.
  • the features 7 can be pressed here. Due to the roof embossing that follows, the embossments 7 come as close as possible to the thread of the screw 3, so that this direction can also be used as best as possible for conductors with a small cross section.
