Definitions

  • the invention relates to a screw terminal for electrical conductors with a sleeve-shaped clamping body folded from sheet metal, the wall opposite the screw thread being formed by two superimposed bends of the side walls.
  • the invention has for its object to provide an inexpensive screw terminal of the type described in the introduction, ie in particular to save material and to simplify the manufacturing process, but burst resistance of the clamping body must be ensured even with extreme tightening of the clamping screw.
  • the one bend has a support tongue which engages in a window of the other bend.
  • an angled connection consisting of a supporting tongue and a window be arranged in the extension of the screw axes.
  • the clamping body is cut to a rectangular shape, so that in principle there is no waste when processing strip-shaped starting material. Punching out the windows and partially clearing the tongues at the bends does not pose any difficulties, just as little as pressing the tongues into the windows, so that after the clamping bodies are folded, the two bends lying on top of one another are secured against being pulled apart transversely to the screw axis.
  • a preferred embodiment of the proposed screw clamp is that the window is attached to the inner and the support tongue to the outer bend, that the support tongue points away from the longitudinal edge of the outer bend and rests with its end against the reveal of the window adjacent to the longitudinal edge of the inner bend .
  • the support tongue can advantageously be pressed from the outside into the window of the inner bend.
  • the window and tongue have mating rectangular contours, preferably with a longer side length in the longitudinal direction of the bend.
  • the cross-sectionally rectangular clamping body shown consists of a top wall (1), two side walls (2 3) and a bottom formed from two superimposed bends (4, 5) of the side walls.
  • the top wall (1) has three passages (6), the edges of which protrude upwards and which are each provided with an internal thread (7).
  • Clamping screws (8) are screwed into the two outer threads, one of which is indicated by dash-dotted lines and, as is known per se, is provided with a wire protection bar (9).
  • the outer bend (5) has two rectangular support tongues (11), which lie under the windows (10), are cut free on three sides and bent upwards at an angle to the level of the bends so that their edges facing away from the longitudinal edge of the bend (5) The edges of the windows lie parallel to the longitudinal edge of the bend (4) and are adjacent to it.
