Definitions

  • the invention relates to a screwless connecting or connecting terminal for electrical conductors with a clamping spring which is to be tensioned before the introduction of the conductor and which clamps the conductor after its introduction and is arranged in a housing.
  • the invention is therefore based on the object of providing a terminal which is even easier to operate, in particular when connecting for the first time, without requiring a high amount of material and assembly for the terminal.
  • This is achieved in a simple manner with a clamp of the above-mentioned type in that there is an operationally clamping force-free clamping element which is supported on the housing on the one hand and which holds the clamping spring on the other hand and which is in two defined end positions and from the outside of the housing at least into the relaxed position is adjustable.
  • This makes it possible to deliver the terminal in the open state ex works, so that the customer does not need to use force when connecting the conductor.
  • the assembly of the conductor is therefore relatively simple.
  • a slidably mounted wedge has proven to be a simple and inexpensive tensioning element.
  • the use of the wedge opens up the possibility of combining the triggering of the tensioning element with the insertion process of the conductor, namely in that an attachment of the wedge when the conductor is inserted can be brought into contact with the insulation of the conductor in the relaxing sense of the clamping spring.
  • the direction of release of the tensioning element and the direction of insertion of the conductor thus coincide.
  • the tensioning element is a plunger which can be locked longitudinally in the spring's springing direction in two end positions.
  • the locking of the plunger can be achieved without considerable effort if the plunger is provided with a locking lug, which, after the plunger has been rotated, is in the tensioned state of the clamping spring and the open state of the clamp an undercut housing is engaged.
  • the plunger is provided with a screwdriver slot, the slot position of which indicates the state of the clamp.
  • the clamping element can be locked in the open state of the clamp.
  • the clamping element is in operative connection with several clamp springs.
  • a known spring clip 3 is housed in an opening 1 of a device housing 2, which can be, for example, the housing of an electromagnetic switching device.
  • the connecting conductor 4 of the spring terminal 3 can, for example, form the fixed contact piece of an electromagnetic switching device.
  • the hairpin-shaped curved leaf spring 5 of the spring clip 3 engages with a breakthrough 6, the bent end 7 of the terminal block 4 and at the same time provides the entry opening for the stripped end 8 of the conductor 9.
  • a wedge 10 is slidably guided, which is shown in FIG 1 apparent position causes tensioning of the leaf spring 5.
  • a rounded recess 11 serves to lock the wedge in the position shown in FIG. 1 in that a corresponding bulge of the leaf spring 5 engages in the recess 11.
  • An angular extension 12 on the wedge 10 serves to push the wedge back into the position indicated by the broken line in order to relax the leaf spring 5 in such a way that the stripped end 8 is clamped in the opening 6.
  • the wedge can be inserted automatically when the conductor 9 is inserted through the edge of the insulation of the conductor.
  • a slot 13 in the wedge 10 allows the wedge to be moved through the passage 14 by means of a screwdriver or by a machine when manufacturing the device. To release the clamp, it is only necessary, for example, to insert a screwdriver into the passage 14 and to press the wedge downwards in the direction indicated by the arrow 15, so that the opening 6 is exposed and the stripped end 8 can be pulled out of the opening. It is therefore not necessary to move the wedge to loosen or connect individual wires.
  • the embodiment shown in FIG. 2 uses a plunger 16 as the tensioning member.
  • the plunger 16 is guided in the opening 1 so as to be longitudinally displaceable.
  • a head start 17 in the housing 2 cooperates with an extension 18 of the plunger 16, in the position shown in FIG. 2, ie with the leaf spring 5 tensioned, so that the conductor 9 with the stripped end 8 can be inserted.
  • the direction of insertion is indicated by arrow 19.
  • the plunger 16 is provided in the form of a screw with a screwdriver slot 20, so that the locking between the extension 18 and the projection 17 can be released by lightly pressing the plunger and rotating it by means of the screwdriver and the plunger relieves the leaf spring 5 in such a way that after insertion the conductor 9 is clamped in the usual way.
  • a latching recess 21 is made, into which the pin-shaped extension 18 engages in the position shown in FIG. 2, ie when the clamp is open. This position securing ensures that the clamp is not adjusted when the device is being transported.
  • Fig. 4 indicates that current flow is enabled, i.e. the clamp is closed and Fig. 5, in which the longitudinal direction of the screwdriver slot 20 is transverse to the longitudinal direction of the conductor, indicates that the clamp must still be closed.
  • FIG. 6 A variant of the embodiment according to FIG. 2 can be seen from FIG. 6.
  • the plunger 16 is guided here in a longitudinally displaceable manner in a housing recess 22.
  • the wall 23 is formed by the formation 24 as an elastically resilient part and serves as a locking projection for the nose 25 on the plunger 16.
  • the wall 23 has an extension 26 engaging around the plunger 16, which ends in an actuation opening 27.
  • the plunger is moved in the direction of arrow 29, for example with a screwdriver, until it engages automatically with the wall 23 for tensioning the leaf spring 5.
  • the clamp according to the invention enables the use of commercially available clamp springs and is only a clamp that can be delivered in the open state by a practically free, simple additional part that does not have to absorb clamping pressures during operation.
