Definitions

  • the invention relates to a screw terminal for connecting one or more connecting wires and / or rails, with a box frame with a thread cooperating with the screw and a terminal frame according to the first part of the single claim.
  • clamping components or clamping elements in so-called simple screw clamps are a fixed metal part as a current-conducting base and either the screw head or a clamping disk located under the screw head, which is roof-shaped and can also be captively clamped to the screw.
  • the screw is usually screwed into a fixed, threaded part in such a way that the conductors are clamped between the part and the screw head or the clamping disk.
  • Box clamps require a fixed rail or support surface and one end of the bolt or a frame pulled against the rail by the screw force is used for clamping.
  • a connecting terminal for connecting several connecting wires is known from CH-A-425 935.
  • This terminal is designed in such a way that it can only be attached to the relevant housing via an extended connecting lug; it is not possible to hold the clamp without connecting lugs.
  • a screw clamp which has a U-shaped part, in the free leg of which a bore is arranged, through which a screw is inserted, which interacts with a box frame with a threaded bore.
  • the invention has for its object to provide a screw terminal of the type mentioned, in which several conductors to be connected, even if they are different in shape and size, can be connected safely and easily with constant clamping force.
  • the screw terminal has a loop-shaped, bent terminal frame which forms a rectangular, closed ring, the end of a side wall of the terminal frame which closes the ring being mechanically coupled to one of the other side walls of the terminal frame and in this way the rectangular one forms a closed ring.
  • a screw terminal with a box frame has become known from DE-U-1 935 560.
  • one leg of a U-shaped pressure bracket is blown in, with the other leg the pressure bracket engages in the interior of the box frame.
  • the clamps are held by an additional element with which the box frame is locked, as can be clearly seen from FIGS. 3 and 4 of DE-U-1 935 560; the pressure bracket is loose in the housing.
  • the screw terminal according to the invention has the box frame and the terminal frame, the latter of which is at the same time a current carrying part, that is to say is firmly seated in the housing.
  • the upper conductor can also be clamped under the screw head. Which is considerably easier than inserting a wire under the pressure bracket of the known clamp. This also results in cost advantages.
  • FIG. 1 A box clamp is shown in FIG.
  • This box clamp has a loop-shaped clamp frame 40, the loop being approximately rectangular in shape such that a side wall 42 is inserted into a recess 44 in the side wall 46 directly adjoining it with an extension 48.
  • the side wall 42 extends through a box frame 50, in the upper side 52 of which an internal thread 54 is introduced, through which a clamping screw 56 can be screwed, which clamping screw simultaneously passes through a recess 60 located in the side wall 42 opposite the side wall 58.
  • a busbar 64 can be clamped to the upper side wall 58 and the screw head 62, whereas a conductor with a round cross section 64 can be clamped between the outer surface of the side wall 42 and the inner surface of the side wall 50.
  • FIG. 2 shows the arrangement according to FIG. 1 in the direction of arrow A.
  • FIG. 3 shows a further embodiment of the invention.
  • the screw terminal has a terminal frame 70, which is also rectangular, but in which a side wall 72 is bent up parallel to the central axis of the clamping screw 56 and - similar to the side wall 42 with the extension 48 in the side wall 46 - in the overhead, the bore 59, through which the clamping screw 56 passes, engaging side wall 58 engages with an extension, not shown.
  • the side wall 58 or better the upper wall 58 has an extension 82 # which runs parallel and at a distance from the side wall 72 outside the clamping frame.
  • the extension 82 # can be used to fix the clamp of FIG. 3 to a housing, similar to the clamp of FIG. 1 with the extension 82.
  • a tab 74 is bent, which serves to guide a conductor 76 clamped between the screw head 62 and the outer surface of the side wall 58.
  • the conductor 64 can of course be clamped between the outer surface 78 of the lower side wall 80 and the inner surface of the side wall 50.
  • the particular advantage of the screw terminal according to the invention is, in particular, that the “user-friendliness”, which lies in the fact that conductors of different cross-sections can be easily connected to a single terminal, as well as various connection means (universal busbars, busbars, busbar blocks, busbar sets, comb rails, set clamps, connecting pieces, etc. ) can be clamped in, is significantly increased.
