  • the invention relates to a screw terminal according to the preamble of claim 1, an installation switching device with a screw terminal according to claim 6, and a method for producing a screw terminal according to claim 8.
  • a generic screw terminal comprises a substantially frame-like clamping member with longitudinal, narrow and broad sides, a clamping screw which is received in a threaded opening of the clamping member, and a the interior of the frame-like clamping member by cross, movably arranged to the clamping part busbar whose broad side in mounted Condition is oriented parallel to the broad side of the clamping member, wherein the clamping member is displaceable by turning the clamping screw in its longitudinal direction relative to the busbar, so that a connection conductor between the clamping screw facing away from the side of the busbar and the clamping screw facing away from the broad side of the clamping part is clamped, wherein the busbar carries at its free end in an approximately rectangular contact plate whose length is greater than the width of the busbar receiving interior of the clamping part, so that the contact plate in the assembled state of the busbar with their free ends on both sides of the frame-like clamping part surmounted.
  • Such erab gleichklemmen are also known as Buchbügelklemmen.
  • the DE 40 13 225 B4 , the DE 101 55 924 A1 , and the EP 0 847 105 A1 show examples of embodiments of generic Buchbügelklemmen.
  • These are usually used in service switching devices, for example in circuit breakers or RCCBs, to connect connecting conductors, be it stripped cable ends of flexible wiring cables or fixed contact lugs of busbar arrangements, to the service switching device.
  • Installation switching devices are known to monitor the current flow on one of an input side leading to an output terminal through the inside of the device current path and turn on or off.
  • the screw terminals are mounted inside the service switching device housing in a terminal receiving space, which is usually housed near the narrow side of such a service switching device.
  • the EP 0 541 459 A1 shows a Switzerlandbügelklemme in an installation device housing, wherein the clamping frame has teeth that cause when tightening the Clamp the two housing halves of the device housing are pulled towards each other.
  • the EP 1 596 471 A1 shows a terminal assembly in which the clamping frame is formed together with the clamped terminal conductor as a replaceable and snap-in a corresponding terminal receiving space of a device module.
  • the US Pat. No. 2,159,757 shows a clamping arrangement in which a terminal conductor can be clamped by means of a cage clamp to a busbar, and the busbar with clamped conductor can then be inserted into a device.
  • the EP 0 893 846 A1 shows a Switzerlandbügelklemme, in which an additional clamping zone is provided for clamping another conductor.
  • the FR 2 459 560 shows a Switzerlandbügelklemme for clamping an insulated connection conductor, wherein means are provided to pierce the insulation when tightening the clamping screw and make an electrical connection to the conductive core of the connection conductor.
  • the busbar is mounted stationary in installation devices with Glasbügelklemmen inside the housing usually. At their the device interior facing free end internal connection conductors are attached, which continue the current path between the input and output terminal, wherein the current path is still performed on other functional components or components inside the housing, for example via a contact point and possibly a thermal or magnetic trigger.
  • the busbar Since the busbar is mounted stationary, shifts the clamping member relative to the busbar upon actuation of the clamping screw. It is often necessary in the manufacture of a service switching device to perform a so-called hot adjustment of the thermal release at the end of the manufacturing process.
  • the busbars of the input and output side terminals are contacted in a tester by probes under a certain contact pressure, it may happen that the busbar is pressed by the contact pressure of the probe from its specified position into the interior of the housing, so that the device no longer usable.
  • the length of the contact plate is smaller than the height of the busbar receiving the interior of the clamping plate.
  • the advantage of the inventive design of a screw is that the clamping part laterally projecting free ends of the busbar can be used as an abutment with which the busbar near the Leiteinfirhrungsungsö réelle the eran gleichklemme can be supported in addition to abutments in the interior of the housing and thereby pushing the fferverbindkletnme is prevented by a pressing on the outside of them probe.
  • the invention Dimensionl réelle the ratio between the length of the contact plate and the length of the busbar receiving the interior of the clamping part allows a simple and fast automatic assembly of the screw terminal according to the invention.
  • the clamping screw receiving threaded opening is mounted in a broad side of the frame-like clamping part.
  • the clamping member may be a stamped and bent part with a particularly reinforced upper broad side, in which the thread is introduced.
  • the busbar receiving the interior of the clamping member then extends in the longitudinal direction of the frame-like clamping plate between the upper and lower broad side.
  • the lower broad side can also be rounded or arcuate.
  • the broad side of the contact plate is aligned approximately perpendicular to the broad side of the busbar. Since the broad side of the busbar approximately parallel to the broad side of the clamping part and perpendicular to the receiving opening for the connecting conductor-carrying longitudinal side of Clamping part is oriented, so that the contact plate extends with its broad side parallel to this receiving opening for the connecting conductor-carrying longitudinal side of the clamping part. The contacting by means of the probe during the hot adjustment can then take place from the same direction, from which in the intended use of the service switching device, a connection conductor would be introduced into the screw terminal.
  • the contact plate is advantageously integrally connected to the busbar.
  • the busbar is formed as a stamped and bent part, and the contact plate is formed after punching the busbar by bending an end piece of the busbar.
  • an installation switching device with an insulating housing, which has at least one front side and a mounting side and the front and the attachment side connecting narrow and broad sides, and which in the narrow sides of a terminal receiving space for a terminal for connecting an electrical Connecting conductor has, with a screw terminal according to the invention, in which near the narrow side of the housing in the housing interior holding means for a stationary mounting of the free ends of the contact plate are provided.
  • the holding means may be designed as plug-in pockets which are mounted near the narrow side of the housing on the inner housing broadside and whose internal dimensions correspond to the outer dimensions of the free ends of the contact plate.
  • a first pocket in the first housing half shell and the second pocket are mounted in the second housing half shell.
  • the screw terminal is then initially inserted with a first side part in the first slot in the assembly, then the second housing half shell is placed on the first housing half shell, in which case the second side part at the same time in the second pocket is introduced. If the two housing halves are then connected to each other, the screw terminal is held almost immovable with the free ends of the bus bar in the pockets.
  • the advantage of the manufacturing method according to the invention is that the steps “punching the busbar”, “bending the busbars” and “placing the clamping parts on the busbar” are consecutively performed on interconnected via the transport strip parts, wherein the transport strip automatically when punching the busbars arises and does not have to be added separately and the bus bars are automatically aligned and positioned for the placement of the clamping part, so that the method can be carried out automated at high speed.
  • a suitably designed production machine gets as a supply of material only an endless metal strip and the prefabricated, frame-like clamping parts. From the sheet metal strip the busbars are punched out, with a lateral strip stops as a transport strip, by means of which the punched busbars are transported to the other workstations.
  • the free end of the busbar is bent so that thereby the contact plate is formed in the predetermined position on the busbar.
  • the busbars with the contact plates are continued to that station at which the clamping parts are pushed onto the busbars.
  • the inventively tuned ratio of the length of the interior of the frame-like clamping part, the length of the contact plate and the width of the insertion opening for the connecting conductor receiving longitudinal side of the clamping part is now important. Because this makes it possible that the clamping part - rotated by 90 °, so that the longitudinal extension direction of the longitudinal side of the frame-like clamping member is parallel to the longitudinal direction of the contact plate - can be pushed over the contact plate and on the busbar.
  • the clamping screw has already been inserted into the clamping part, before it is pushed onto the busbar. Then, before singulating the screw terminals of the sheet metal strip, the clamping screw are tightened so far that the clamping part is fixed to the busbar.

  • In the upper broad side 8 is an opening 9 with internal thread for receiving the clamping screw. 2
  • the upper broad side 8 opposite lower broad side 10 of the clamping part 3 is executed here rounded. However, it could also be flat, but this would mean an additional processing step in the production of the clamping part 3.
  • the clamping part 3 has an open frame shape, whereby on the longitudinal side 11 an insertion opening 12 is formed for the connecting conductor to be connected.
  • the narrow side 13 of the clamping part 3 is formed due to the slit of the clamping part 3 forming the conductor strip 5 substantially by two mutually parallel longitudinally extending webs 14, 15 with an intermediate recess 16, wherein the webs 14, 15 are held together with crossbars 17.
  • the busbar 3 has substantially the shape of a rectangular, flat conductor piece. It is guided displaceably in the interior of the clamping part 3 between the upper and the lower broad side 8, 10 in the longitudinal extension direction of the clamping part 3. At its the insertion opening 12 facing away from the free end 18, the busbar for connecting a further, leading into the interior of the service switching device connection conductor is established. For this purpose, it carries there a rectangular recess and a bore 19. Furthermore, the busbar is provided there at a bending edge 20 with a stepped turn, so that the free end 18 is displaced parallel to the rest of the busbar by a distance x down.
  • the insertion opening 12 facing free end 21 of the busbar 3 is bent at a bending edge 24 by about 90 ° upwards, so that it forms a contact plate 22.
  • the contact plate 22 has a rectangular shape and extends with its broad side 23 parallel to the longitudinal side 11 of the clamping part 3, wherein it extends in the insertion direction of a connecting conductor in front of the longitudinal side 11 of the clamping part 3.
  • busbar 3 guide tongues 25 are further formed, by means of which the busbar 3 in the recess 16 between the two parallel webs 14, 15 are guided on the narrow side 13 of the clamping part 3.
