Definitions

  • the invention relates to a clamp for clamping electrical lines, with an open or closed frame, which has a U-shaped first section and a second section connecting or bridging the leg ends with a threaded bore, and with a clamping screw, which in the threaded bore can be screwed in,
  • Such terminals are mainly used as terminals for electrical conductors in circuit breakers, residual current circuit breakers, contactors and the like.
  • the lead wires are clamped between the free end of the screw shaft and the base of the U-shaped frame, and the leads can only be connected in one direction.
  • Clamps of this type have also become known, in which a U-shaped pressure bracket is additionally provided. Its leg is fork-shaped and grips the Screw shaft immediately below the screw head, whereas the other leg engages in the clamping opening and thereby covers the free end of the screw shaft, so that the electrical cable can be clamped between the outer surface of the other leg and the inner surface of the U-shaped frame. It is possible to design the pressure bracket in two pieces; one part is L-shaped and to form the other, the free end of the screw covering leg is made in the pressure bracket, a slot-like recess through which another part can be pushed through to form the other leg. This further part can, for example, have an extension, so that there is a further connection possibility.
  • One or more conductor wires could be connected to these terminals and only ever in one direction. Of course, jamming of lines between the screw head or the one leg of the pressure bracket and the leg end edges of the frame is also possible.
  • the object of the invention is to provide a clamp of the type mentioned that can be used more universally.
  • the clamp additionally has a U-shaped pressure bracket, one leg of which is fork-shaped and comprises the screw shaft in the region of the screw head and the other leg of which covers the free end of the clamping screw in the interior of the frame, then a further advantageous embodiment of the invention consists in that the other leg has lugs on both sides, which engage in the slots for guiding the pressure bracket.
  • a connection can also be made transversely to the direction of the frame, in such a way that connecting wires through the side slots, that is, the slots that are in the legs of the frame are inserted and can be clamped by means of the screw or the other leg of the U-shaped pressure bracket.
  • the connection direction is changed.
  • Another, particularly significant advantage of this embodiment is that the pressure bracket is guided with its two extensions in the slots and is thereby held captive and movable back and forth on the clamp or on the frame.
  • a larger number of wires of small cross-section can be clamped at the same time. Because the slots in the legs extend to the base of the U-shaped section, wires can also be clamped, the cross section of which is 0.75 mm 2.
  • a clamp 10 has a frame with a U-shaped first section 12 with two legs 14 and 16 which are connected by a semicircular region 18 (bottom of the U-shaped section). Both legs have rectangular recesses 20 and 22 in the region of the leg end, to which slots 24 and 26 adjoin, which protrude into the semicircular region - starting from the recess 20 and 22, respectively.
  • An unslit region 28 is provided between the slots 24 and 26 in the semicircular region.
  • the width of the recess measured parallel to the free edge 30, is larger than the width of the slot 24 or 26.
  • a nut 32 is inserted, which has extensions 34 on both sides (only the :: 'extension rethts can be seen in the drawing Figure 1), which engage in the recesses 20 and 22, whereby the mother in the first Section is held captive; the mother connects the legs and is also referred to as the second section.
  • the nut 32 has a bore 35 with an internal thread, into which the shaft 38 of a clamping screw 40, which is provided with an external thread 36, is screwed.
  • the clamping screw 40 is a head screw with a head 42.
  • the clamp also has a pressure bracket 50 which is U-shaped with a first leg 52 and with a second leg 54, the first leg 52 being fork-shaped with a slot-like recess 56 into which the screw shaft engages directly under the screw head 42 .
  • the pressure bracket can be connected to the leg 52 or, via this, captively to the screw 40.
  • the other leg 54 engages in the interior of the frame and thereby covers the free end face of the screw shaft 38.
  • Lugs 58 and 60 are attached on both sides of the leg 54, which in the Engage slots 24 and 26 and contribute to guiding the pressure bracket 50.
  • the free end of the second leg 54 is bent slightly upward, that is to say towards the other leg 52, see reference number 62.
  • edges 30 of the two legs 14 and 16, which project beyond the center, have semicircular grooves 64 and 66 which are aligned with one another and are arranged on one side of the screw shaft 38.
  • FIG. 1 and 2 show how one or two connecting conductors 70, 72 and 74 can be clamped between the base of the U-shaped frame 12, that is to say between the region 18 and the outer surface of the second leg 54 of the pressure bracket 50. It is also possible, as can be seen in FIG. 3, to insert a lead wire 76 into the grooves 64 and 66 and to clamp it between the first leg 52 and the groove 64 or 66.
  • a comb rail 78 can also be attached to the clamp; this comb rail, which is used as a busbar in circuit breaker installations, is designed in the form of a strip and has recesses 80 and 82, respectively, with which the strip 78 between the edges 30 of the legs 14 and 16 and the second leg 52 of the U-shaped pressure bracket 50 can be attached.
  • an L-shaped clamping piece 84 is provided, which is fork-like on its one leg (i.e. has a similar recess as the busbar 78), with which the connection piece 84 between the free leg ends 30 and the first Leg 52 of the pressure bracket can be attached or jammed.
  • the recess in the part 84 has the reference number 86.
  • the clamp can now be produced in such a way that the cutouts 20 and 22 and the two slots 24 and 26 are punched out of a sheet metal strip. Then the strip is bent into a U-shaped frame such that the extensions on the nut 32 engage in the two recesses 20 and 22. At the same time, the pressure bracket is used so that the two lugs 58 and 60 can simultaneously engage with the extensions in the slots.
  • first leg of the U-shaped pressure stirrup fork-like form 50 it is also possible to provide it with a circular hole, can be inserted therethrough during assembly benschaft by then the S chrau-. This circular hole could then be narrowed in the region of an undercut between the threaded region of the shaft and the screw head 42.
  • the narrowing is of course also possible if the first leg 52 is provided with the recess 56 in the manner of a fork. In this way, a double captivity is achieved: on the one hand the captivity due to the guidance of the lugs in the slots and on the other hand due to the mounting of the bracket in the area of the undercut between the threaded area of the screw shaft and the head.
  • the frame in a closed manner, in which the first section of the frame is bridged in the region of its leg ends by a second section which is integrally formed on one or both legs. It is possible to manufacture the frame by means of a stamping and bending process or also by means of a drawing or extrusion process and to subsequently incorporate the side slots.
