Definitions

  • the invention relates to a conductor terminal according to claim 1.
  • the invention also relates to a method for assembling such a conductor terminal according to claim 18.
  • DE 10 2013 101 830 A1 discloses a conductor terminal with an insulating material housing and a contact insert with a clamping spring, wherein the contact insert can be placed on a housing part and then used in combination in the insulating material housing.
  • a second latching connection be arranged between the closure part and the contact insert, with the closure part and the contact insert being able to be latched together by the second latching connection, with a side wall of the insulating material housing being designed as a blocking element, with the blocking element being able to be released the second locking connection is blocked.
  • a conductor connection terminal that is safe to handle can be provided in a preassembled state.
  • the double latching namely the closure part in relation to the insulating material housing and the closure part in relation to the contact insert, makes it possible to provide a preassembled unit consisting at least of a closure part and contact insert and a more stable conductor terminal. The influence of force therefore leads to no or reduced deformation of the conductor connection terminal.
  • closure part is held securely in the insulating housing, even in the event of external forces such as tensile or torsional forces acting on the conductor terminal.
  • the clamping spring can have a contact leg and a spring bow arranged between the contact leg and the clamping leg.
  • the latching connections of the conductor terminal are not limited to one of these embodiments. Rather, these latching connections can also be formed in combination or in an increased number on the conductor connection terminal. For example, it is conceivable that the same type of Snap connection is formed at least one, two or three times on the conductor terminal according to the invention.
  • the second latching connection can be designed as a latching arm of the closure part, with the latching arm encompassing the busbar of the contact insert.
  • the locking arm is arranged on the closure part.
  • the latching arm is guided past the contact insert, with the end of the latching arm gripping the contact insert and thus securely latching the contact insert on the closure part.
  • a latching hook can be provided on the latching arm, which engages behind a latching edge on the busbar.
  • the insulating material housing has a blocking element, the blocking element blocking the detent element from being released. It is also conceivable that the insulating housing itself is the blocking element. If the preassembled closure part with the contact insert is guided into the insulating material housing, the insulating material housing blocks the second latching connection from being released.
  • the aforementioned design of the second latching connection as latching arms can no longer be deflected, since these are blocked by the presence of the insulating material housing and/or the blocking element.
  • a conductor connection terminal that is functionally reliable and safe to handle is provided, with the second latching connection not being able to be released without the closure part being dismantled from the insulating material housing.
  • the first latching connection can be designed as a latching hook of the insulating material housing, with the latching hook engaging in an opening in the closure part.
  • the latching hook is arranged on the insulating material housing. The latching hook can be guided into an opening in the closure part, with the latching hook latching the insulating material housing to the closure part there.
  • the first snap-in connection can be designed as a lug of the closure part, with the lug encompassing a web on the insulating material housing.
  • the tab is arranged on the closure part, the tab being designed as a flat piece of material with a fastening hole.
  • the first latching connection can be designed as a projection of the closure part, with the projection engaging in a recess in the insulating material housing.
  • the projection can in particular be T-shaped.
  • the projection is arranged on the closure part, the closure part being guided into a recess of the insulation housing when the closure part is mounted on the insulating material housing.
  • a possible T-shaped configuration of the projection can prevent the first locking connection from being released. The connection can therefore no longer be canceled without destroying the conductor connection terminal.
  • Such configurations of the latching connections can occur in any conceivable combination.
  • the first latching connection is designed as three projections of the closure part, with one of the projections being T-shaped.
  • a tab to be arranged on the closure part and for two latching hooks to be arranged on the insulating material housing, which in turn each engage in an opening in the closure part.
  • the different combinations of snap-in connections allow a conductor connection terminal that is safe to handle to be provided.
  • a test opening can be arranged on the closure part.
  • the test opening can be aligned transversely to the electrical conductor to be clamped, with the test opening extending from a surface of the closure part through the closure part extends through to the contact insert.
  • the contact insert can be contacted with external measuring devices through such a test opening.
  • the conductor connection terminal can have at least one, preferably two, actuating levers, the actuating lever being set up to deflect the clamping leg. This enables the clamping point to be opened and/or closed easily without any additional aids.
  • the conductor connection terminal can have a guide contour for guiding the first snap-in connection and/or the second snap-in connection.
  • the guide contour can be a chamfer on the insulating material housing and/or closure part.
  • Such a guide contour simplifies the assembly of the conductor connection terminal.
  • the openings of the closure part can have a chamfer, in which case the latching hook of the insulating housing can be guided over the chamfer into the latching position.
  • the insulating material housing and the closure part can be caulked against one another in the area of the first latching connection.
  • Mechanical caulking of the closure part relative to the insulating material housing, which causes plastic deformation of the closure part and/or the insulating material housing, means that the components can no longer be detached from one another without destroying them by applying a corresponding amount of force.
  • the first snap-in connection and/or the second snap-in connection can be arranged in a central area of the conductor connection terminal.
  • the conductor connection terminal can have a symmetrical structure, with the first latching connection and/or the second latching connection being arranged in a plane of symmetry of the conductor connection terminal.
  • the first snap-in connection and/or the second snap-in connection can be arranged on the plane of symmetry of the conductor connection terminal, with the plane of symmetry extending perpendicular to the direction of conductor insertion.
  • the conductor connection terminal can have two conductor entry openings and two clamping springs, the conductor entry openings being arranged at diametrically opposite ends of the conductor connection terminal.
  • the first latching connection and/or the second latching connection can be arranged between the clamping springs of the contact insert.
  • the first latching connection between the closure part and the insulating housing can be provided on diametrically opposite end regions of the conductor connection terminal in the direction of longitudinal extension and thus also outside the plane of symmetry of the conductor connection terminal.
  • the direction of longitudinal extent denotes the direction in which the electrical conductors are inserted into the conductor insertion openings.
  • a conductor connection clamp with two opposite clamping points for two electrical conductors can be provided, which has a high level of stability against deformation of the insulating material housing and/or the closure part.
  • the conductor connection terminal according to the invention has a multiplicity of contact inserts arranged next to one another.
  • two, three, four or five contact inserts can be arranged side by side in an insulating housing, with the contact inserts each having two clamping springs for two electrical conductors to be clamped.
  • figure 1 shows a conductor terminal 1 in a perspective view in a first embodiment.
  • the base body of the conductor connection terminal 1 is formed from an insulating material housing 2 and a closure part 3 , the closure part 3 being inserted into an assembly opening in the insulating material housing 2 .
  • the conductor terminal 1 has two conductor entry openings 4a, 4b for receiving electrical conductors.
  • test opening 6 is arranged on the closure part 3 , the test opening 6 extending perpendicularly from a surface of the closure part 3 into the interior of the insulating material housing 2 . Such a test opening allows access to electrically conductive components inside the insulating housing 2 with external measuring devices.
  • the closure part 3 is fixedly connected to the insulating material housing 2 via a first latching connection 7 .
  • the first latching connection 7 is designed as a projection 8 of the closure part 3 , the projection 8 engaging in a recess 9 of the insulating material housing 2 and thus fixing the closure part 3 to the insulating material housing 2 .
  • the conductor connection terminal 1 is constructed fully symmetrically in relation to a plane of symmetry SE, with the first latching connection 7 being arranged in the plane of symmetry SE.
  • the plane of symmetry SE extends perpendicularly to a conductor insertion direction L.
  • FIG 2 shows a closure part 3 of a conductor terminal 1 in a perspective view figure 1 with actuating levers 5a, 5b arranged thereon.

  • the second latching connection is provided for latching the closure part 3 to a contact insert 12 .
  • the second latching connection 10 is arranged on the same plane of symmetry SE as the first latching connection 7 . Due to the double latching, namely the closure part 3 against the insulating material housing 2 and the Closure part 3 opposite the contact insert 12, a conductor terminal 1 that is safe to handle can be provided.
  • two projections 8 are arranged on opposite sides of the closure part 3 and are intended for engagement in a recess 9 of the insulating material housing 2 .
  • figure 3 shows a conductor terminal 1 figure 1 in a sectional view, the section lying in the plane of symmetry SE. It can be seen that a busbar 13 of the contact insert 12 is arranged in the interior of the insulating material housing 2 , the second latching connection 10 embodied as latching arms 11 being passed laterally next to the busbar 13 and encompassing the busbar 13 .
  • the first latching connection 7 designed as projections 8 engages in the recesses 9 of the insulating housing 2 .
  • the insulating material housing 2 is designed as a blocking element 14, with a lateral wall of the insulating material housing 2 blocking a release of the second latching connection 10 by preventing the latching arm 11 from being deflected.
  • the latching arms 11 of the second latching connection 10 are blocked by the presence of the insulating housing 2 .
  • Closing part 3 of conductor terminal 1 shown is not caulked against insulating housing 2 in the area of first snap-in connection 7 .
  • Caulking could, however, take place, for example, by applying a force F against the projection 8 of the closure part 3 .
  • the projection 8 is deformed in such a way that sections of the projection 8 flow into cutouts 9a in the recess 9 and it is no longer possible to release the first latching connection 7 .
  • the projections 8 of the first locking connection 7 can then by the deformation of the projection 8 can no longer be pulled out of the recesses 9. After caulking the closure part 3 against the insulating material housing 2, it would no longer be possible to disassemble the conductor connection terminal 1 without destroying it.

  • the conductor terminal has an insulating material housing 2 and a closure part 3 , a contact insert 12 being arranged in the interior of the insulating material housing 3 .

  • a further first latching connection 7a between the closure part 3 and the insulating material housing 3 is designed as a latching hook 22 of the insulating material housing 2 .
  • the latching hooks 22 are arranged on the diametrically opposite ends of the insulating material housing 2 .
  • the latching hooks 22 engage in corresponding openings 23 on the closure part 3 and thus latch the insulating material housing 2 and the closure part 3 together.
  • This additional snap-in connection 7a thus takes place at diametrically opposite end regions of the conductor terminal 1.
  • the additional snap-in connection 7a is optional and can be used at low Requirements for the latching of the closure part 3 in relation to the insulating material housing 2 are omitted.
  • the additional first latching connection 7a can also be secured against loosening of the latching by caulking the projection or also the insulating material housing 2 .
