Definitions

  • the invention relates to a screwless connecting or connecting terminal for electrical conductors with a clamping spring to be tensioned before the insertion of the conductor and after its insertion, which is arranged in a housing and which can be clamped in a ring or hairpin shape.
  • the invention is therefore based on the object of providing a clamp which can be actuated even more easily, in particular when connecting for the first time, without requiring a high outlay in terms of material and assembly for the clamp.
  • This is achieved in a simple manner in that one end of the clamping spring can be locked in the tensioned state at a locking projection assigned to the other end, the locking being able to be canceled by the elastic bending of the other end from the outside of the housing and the conductor being released by the one End is clampable.
  • This has the advantage that the terminal can be delivered from the factory in the open state, so that the effort required by the customer when connecting the conductor is eliminated.
  • the assembly of the conductor is therefore relatively simple.
  • the conductor only has to be inserted and the clamp loosened, ie no coordination between the application of the pressure and the simultaneous insertion of the conductor is necessary. Furthermore, no additional parts for locking, such as wedges or rotatably mounted locking members, are necessary, since the clamping spring takes on both functions, namely the locking function and the clamping function. In addition, relatively high pull-out forces can be achieved, since self-locking occurs between the conductor and the clamping spring when the conductor is pulled. At least when using solid wires, for example in installation technology, the clamp can be automatically closed by pushing the conductor against the other end of the clamp spring to break the snap connection.
  • clamping spring Tensioning the clamping spring at a later point in time and releasing it from the outside would be possible if housing openings are provided opposite both ends of the clamping spring.
  • the clamping spring has a detached tab. Additional support means for the clamping spring on the housing can be saved if the clamping spring can be locked in a housing recess.
  • additional mounting means for a device connection rail can be spared if a device connection rail is additionally inserted in the housing recess and has openings adapted to the housing openings, since at least one end of the clamping spring bears against the device connection rail during device operation.
  • a clamping spring 3 is latched to housing projections 4 in a housing recess 1 of a device housing 2, which can be, for example, the housing of an electromagnetic switching device.
  • One end 5 of the leaf-shaped clamping spring is used to clamp the conductor 6, which can be inserted in the direction of arrow 7.
  • the current is passed on via a device connecting rail 8 which is inserted in the housing recess 1.
  • the other end 9 of the clamping spring 3 lies with an angled end on the device connection rail 8 more or less parallel to the one end 5 and has in the end region a slot-shaped recess 10, into which the end 5 can be pressed and locked in the tensioned state.
  • a screwdriver blade 11 can be inserted into the clamping spring end 5 opposite housing opening 12 are inserted, which is aligned with an opening 13 in the device connection rail.
  • the free end 5 of the clamping spring 3 is tensioned and then snaps into the recess 10.
  • the conductor 6 can be inserted and by inserting the screwdriver into the housing opening 14, which is aligned with the opening 15 in the device connection rail 8, the other end 9 of the clamping spring is pivoted, ie one end 5 of the clamping spring is released so that this Conductor 6 presses against the device connection rail 8 - as mentioned above - with the effect of self-locking.
  • FIG. 2 differs from that of FIG. 1 in that the device connection rail is designed as a metal cage 16, so that the forces applied by the clamping spring do not act on plastic parts. Furthermore, the slot-shaped recess 10 is replaced by a sheared tab 17 and the other end 9 is angled to provide a better contact surface for the screwdriver blade 11.
  • the housing projections 4 are stamped in the metal cage 16 here.
