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.
  • 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 screwed into a fixed, threaded part, such that the conductor between the part and the screw head or the clamping disc can be clamped.
  • 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.
  • All of these known clamps function in such a way that two elements with clamping surfaces are moved towards one another, with all conductors to be connected, such as, for. B. wires, cable lugs or rails are clamped together between the two elements.
  • a connecting terminal for connecting several connecting wires is known from CH-PS 425 935.
  • This clamp is designed so 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.
  • the object of the invention is to provide a screw terminal of the type mentioned, in which several conductors to be connected, even if they differ in shape and size, can be connected safely and easily.
  • clamping frame is loop-shaped and extends with a side plane through the box frame and that the screw is screwed into the box frame, the screw head being outside the terminal frame, such that the box frame against the outer surface of the Box frame penetrating terminal frame side is pulled.
  • a screw terminal with a box frame has become known from DE-GM 19 35 560.
  • 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 clearly shown in FIGS. 3 and 4 of DE-GM 19 35 560; 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 immediately adjacent side wall 46 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 between 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. 4 in the direction of arrow A.
  • 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. With the extension 82 ', the clamp of FIG. 3 can be fixed to a housing, similar to the clamp of FIG. 1 with the extension 82.
  • the particular advantage of the clamps 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 clamp, as well as various connection means (universal busbars, busbars, busbar blocks, busbar sets, busbars, set clamps, connectors, etc. ) can be clamped in, is significantly increased.
