Definitions

  • the invention relates to a contacting device for contacting an electrical conductor to an electrical conductor track, the electrical conductor being connected to the electrical conductor track by means of push-in clamping technology.
  • a contacting device with which an electrical conductor can be contacted to an electrical conductor track, for example a busbar, by means of plug-in clamping technology usually has a contact clip in a cavity of a housing, which comprises at least one resilient leg.
  • a contact clip By means of the resilient leg of the contact clip, an electrical conductor is pressed against the electrical conductor track or conductor rail when it is pushed into the cavity of the housing of the contacting device and is fixed thereto with a clamping fit.
  • the contact clip is arranged in the cavity of the housing in the insertion web through which the electrical conductor is inserted into the contacting device.
  • the resilient leg of the contact clip When the electrical conductor is inserted into the cavity of the contacting device, the resilient leg of the contact clip must be deflected from its initial position by the electrical conductor against the restoring force of the contact clip in order to fix the electrical conductor in the clamped seat due to the restoring force of the resilient leg of the contact clip.
  • a force When the electrical conductor is pushed into the cavity of the contacting device, a force must be applied to overcome the restoring force of the resilient leg of the contact clip.
  • a stripped cable With a conventional push-in terminal, a stripped cable must be pushed into the contacting device with a greater force than the restoring force of the resilient leg of the contact clip.
  • a contacting device for realizing a three-phase busbar connection using push-in clamping technology must withstand high insertion forces when the electrical conductor is pushed in.
  • One concern of the present invention is to specify a contacting device for contacting an electrical conductor on an electrical conductor track, in which little effort is required to fix the electrical conductor in the contacting device and thus to contact the electrical conductor to the electrical conductor track.
  • a contacting device for contacting an electrical conductor to an electrical conductor track, in which only a small amount of force is required to contact the electrical conductor to the electrical conductor track, is specified in claim 1.
  • the contacting device Inside a housing of the contacting device, the contacting device according to the invention comprises a contact clip with a first section and a second section.
  • the first section of the contact clip is under a bending stress and has an end with which the electrical conductor can be fixed in a clamped fit on the electrical conductor track.
  • the contact clip is shaped in such a way that the end of the first portion of the contact clip rests against a material projection that protrudes from the second portion of the contact clip before the electrical conductor is inserted into a cavity of the contacting device.
  • the contact clip is also movably arranged in the cavity of the housing of the contacting device such that the electrical conductor is pressed against the second section of the contact clip when it is pushed into the cavity of the contacting device, whereby the second section of the contact clip and the material projection are displaced in such a way that the end of the first section of the contact clip is released from resting against the material projection and is pressed against the conductor as a result of the bending stress of the contact clip, so that the conductor is held in a clamped fit on the conductor track.
  • the contact clip which is locked on the material projection in its initial state before the electrical conductor is pushed into the cavity of the contacting device, can be used universally in terminal blocks and electrical switching devices, which can now also be provided in the open state for contacting an electrical conductor to an electrical conductor track or busbar .
  • the contact clip is designed as a clamping spring, with the latching of the resilient leg of the contact clip in the initial state on the material projection and the fixing of the electrical conductor on the electrical conductor track being ensured by a single element.
  • the Figures 1A and 1B each show a schematic representation of a contacting device 1 for contacting an electrical conductor 10 to an electrical conductor track 20, in which only a small amount of force is required to fix the electrical conductor to the electrical conductor track when plugging the electrical conductor into the contacting device.
  • the contacting device 1 comprises a housing 100 with a first opening 101 for inserting the electrical conductor 10 into a cavity 104 of the housing and with a second opening 102 for inserting the electrical conductor track 20 into the cavity 104 of the housing.
  • the electrical conductor track can be, for example, a busbar with which an electrical signal can be applied to an electrical device, for example a relay or a circuit breaker.
  • the contacting device 1 comprises a contact clip 200 in which Cavity 104 of the housing 100 is arranged.
  • the contact clip 200 has a first section 210 with an end 211 for pressing the conductor 10 against the electrical conductor track 20 . Furthermore, the contact clip 200 has a second section 220 from which a material projection 221 of the contact clip protrudes.
  • the contact clip 200 is designed to be bent in the cavity 104 of the housing in such a way that the first section 210 is under bending stress and is therefore designed as a resilient leg. Because of the bending stress, the end 211 of the first section 210 of the contact clip is pressed against the material projection 211 in an initial state before the electrical conductor 10 is inserted into the cavity 104 . In the initial state, the contact clip 200 is thus in a state where it is latched to the material projection 211 .
  • the second section 220 of the contact clip 200 is arranged in the cavity 104 below the first opening 101 of the housing and above the bottom surface 105 of the cavity 104, so that when the conductor is pushed into the cavity 104 through the first opening 101 of the housing 100 in the longitudinal direction of the first opening 101 is pressed against the second portion 220 of the contact clip.
  • the second portion 220 of the contact clip 200 is movably arranged in the housing 100 such that the second portion 220 of the contact clip and the material projection 221 are displaced towards the bottom surface of the cavity when the conductor 10 is pressed against the second portion 220 of the contact clip 200 .
  • the second section 220 of the contact clip is resiliently arranged at a distance above the conductor track 20 or the bottom surface 105 of the cavity of the housing, so that it yields when pressed against by the end of the electrical conductor 10, for example a ferrule, and moves in the direction of the bottom 105 of the Cavity 104 is deflected. As a result, the material projection 221 is also pressed down and the end 211 of the first section 210 of the contact clip is unlatched or released from the latched position.
  • FIG 1 the maximum stroke h for unlatching the end 211 of the first section 210 of the contact clip latched to the material projection 221 is shown.
  • the section 220 By moving the section 220 in the direction of the section of the electrical conductor track arranged underneath, the end 211 of the first section 210 of the contact clip 200 is released from its contact with the material projection 221 and as a result of the bending stress of the first section 210 of the contact clip 200 against the conductor 10 pressed, so that the conductor 10 is held in a clamped fit on the conductor track 20.
  • the contacting device 1 has a guide element 300 in the cavity 104 of the housing 100, along which the contact clip 200 is guided.
  • the guide element 300 is designed in such a way that the first section 210 of the contact clip 200 is under the bending stress. As a result of this bending stress, the end 211 of the first section 210 of the contact clip is pressed against the material projection 221 in the initial state.
  • the guide element 300 can have various functional components.
  • the guide element 300 can have a stop 310 for limiting a movement of the first section 210 of the contact clip 200 between the stop 310 and the material projection 221 .
  • the stop 310 of the guide element 300 is arranged in the cavity 104 at a position such that the bending stress of the first section 210 of the contact clip is higher when the first section 210 of the contact clip is applied to the stop 310 than when it is applied to the material projection 221 of the contact clip.
  • the stop 310 can be arranged in the cavity 104 at a small distance behind the material projection 221 .
  • the second section 220 of the contact clip 200 is arranged in the housing 100 essentially perpendicular to the longitudinal direction of the first opening 101 and can in particular be arranged parallel to the bottom surface 105 of the cavity 104 .
  • the contact clip 200 has a third section 230 which is arranged in the housing 100 essentially perpendicular to the second section 220 of the contact clip 200 .
  • the contact clip between the second section 220 and the third section 230 is bent by approximately 90°.
  • the guide element 300 can according to a further embodiment, have a first system 320 against which the third section 230 of the contact clip 200 rests.
  • the contact clip 200 has a fourth section 240 adjoining the third section 230 .
  • the fourth section 240 has a bent area 241 on which the contact clip is bent in an approximately semicircular manner.
  • the guide element 300 can have a second abutment 330 on which the curved region 241 of the fourth section 240 of the contact clip rests.
  • a fifth section 250 which runs approximately parallel to the third section 230 of the contact bracket, connects to the fourth section 240 of the contact bracket.
  • Fifth section 250 is followed by first section 210 of the contact clip, which, starting from fifth section 250 of the contact clip, is bent in the direction of material projection 221 .
  • the embodiment of the contacting device 1 shown has the guide element 300, in contrast to the Figure 1A embodiment shown a support 340 on which rests the second portion 220 of the contact clip.
  • the support 340 of the guide element 300 is arranged at one end of the second section 220 of the contact bracket, at which the second section 220 of the contact bracket merges into the third section 230 of the contact bracket.
  • the second system 330 of the guide element 300 is omitted.
  • the first section 210 of the contact clip has a greater spring effect.
  • the resulting lengthening of the clamping lever length of the contact clip 200 gives the contact clip, in particular the first section 210 of the contact clip, better elasticity than when the bent area 241 of the fourth section 240 of the contact clip rests on the second contact 330.
  • the material projection 221 can be designed as a lug for latching the end 211 of the first section 210 of the contact clip 200 .
  • the nose is bent out of a plane of the second section 220 of the contact clip.
  • the lug can be designed, for example, as a rectangular web of material that is cut out of the second section 220 of the contact clip on all side edges and is still connected to the second section 220 of the contact clip only on one side edge. At this connected side edge, the material projection 221 is bent upwards out of the plane of the second section 220 of the contact clip. For example, this is in Figure 3B shown.

  • the second section 22 of the electrical conductor track 20 connects to the first section 21 and runs in the cavity 104 of the housing of the contacting device perpendicular to the first portion 21 of the electrical conductor track 20.
  • the second portion 22 may have a projection 23, on whose function in the description of Figures 7A and 7B will be dealt with in more detail.
  • the Figures 2A to 2C show different embodiments of the guide member 300.
