Definitions

  • the invention relates to a conductor connection terminal for connecting an electrical conductor by means of an insulation displacement connection.
  • a conductor terminal is, for example, from WO 98/33235 A1 known.
  • the invention is based on the object of specifying a conductor connection terminal which is improved in comparison thereto and which is also suitable for the transmission of high currents.
  • a conductor connection terminal for connecting an electrical conductor by means of an insulation displacement connection, the conductor connection terminal having at least one insulation displacement connection, a pressure piece that can be acted upon by means of an actuating force, for example generated manually, a stamp acting on the electrical conductor and a stamp between the pressure piece and has an energy accumulator that acts on the stamp, the insulation displacement connection having an insulation displacement contact with two contact blades arranged next to one another, a cutting slot being formed between opposite sides of the contact blades, the force of the energy store acting in the longitudinal direction of the cutting slot.
  • the conductor connection terminal according to the invention enables simple handling for the user when connecting an electrical conductor, since the electrical conductor does not first have to be stripped. This is of particular advantage with large conductor cross-sections, since in this case stripping is associated with an increased amount of work.
  • the conductor connection terminal can be set up in particular for connecting an electrical conductor with a cross-sectional area of at least 70 mm 2 .
  • the force accumulator allows a permanent compressive force to be exerted on an electrical conductor clamped between the contact blades, so that a long-term stable connection of the electrical conductor with the insulation displacement contact can be ensured.
  • the force accumulator is effective with regard to the absorption and release of the force stored in it between the pressure piece and the plunger.
  • the force accumulator can be arranged partially or completely between the pressure piece and the plunger.
  • the energy accumulator can be designed, for example, as a compression spring, tension spring or elastic block of material, optionally in combination with a force deflection mechanism.
  • the energy accumulator can be designed, for example, as a spiral spring or as a plate spring.
  • the electrical conductor With such an insulation displacement contact, the electrical conductor, which is still provided with the insulation, is simply pressed on one side against the contact blades and from there pressed into the cutting slot.
  • the insulation of the electrical conductor is severed by the contact blades, so that the contact blades come into electrical contact with the electrically conductive inner material of the electrical conductor, for example with stranded wires or a solid conductor.
  • the cutting slot can be U-shaped or V-shaped, for example, viewed in the conductor insertion direction.
  • the conductor terminal has a manual actuating element which is coupled to the pressure piece or is part of the pressure piece, the manually generated actuating force being transferrable to the pressure piece by the manual actuating element.
  • the conductor connection terminal has its own operating element, so that an external tool or other object does not have to be used for manual operation.
  • the manual actuating element can be designed, for example, as a pivotable actuating lever or as an actuating push button.
  • the design of the actuating element as a pivotable actuating lever is advantageous, since greater conductor contact pressure forces can be transmitted to the electrical conductor with such an actuating lever.
  • the conductor connection terminal has a return safety device, by means of which the actuating element is secured in an actuated end position against a restoring force of the energy store.
  • the actuating element can thus be secured or held by the reset safety device in the state in which the plunger rests against the electrical conductor and presses it into the cutting slot due to the force of the energy store.
  • the reset safety device can be designed in different ways, for example as a latching of the actuating element.
  • the reset safety device can also have an actuating contour of the actuating lever in an over-center position, for example an eccentric actuating contour.
  • the actuating lever has an eccentric actuating contour and is coupled to the pressure piece via this eccentric actuating contour. With a simple and reliable mechanical design, this allows large forces to be transmitted from a manual actuation area of the actuation lever to the pressure piece.
  • the punch has a conductor guide contour that supports the guidance of the electrical conductor from a conductor insertion opening of the conductor connection terminal in the direction of the cutting slot.
  • the stamp has an additional function, namely guiding the electrical conductor to the terminal point.
  • the conductor routing contour can be formed, for example, as a longitudinal groove running in the conductor insertion direction of the electrical conductor in the plunger.
  • the conductor connection terminal has a housing with a conductor insertion opening for inserting the electrical conductor to the insulation displacement contact, with a conductor insertion direction of the electrical conductor being defined by the conductor insertion opening, which is perpendicular to one through the two arranged side by side Contact cutting running plane runs.
  • the electrical conductor simply has to be in Conductor insertion direction are inserted through the conductor entry opening in the housing of the conductor terminal.
  • An end stop can be present in the housing of the conductor connection terminal, which limits the maximum conductor insertion depth. When the user feels that the end stop has been reached, the electrical conductor only has to be pressed into the cutting slot by actuating the manual actuating element, so that it is mechanically fixed there using the insulation displacement function and is also electrically contacted.
  • an electrical conductor clamped on the insulation displacement contact between the two contact blades arranged next to one another is permanently loaded with the force of the energy store. This ensures a long-term stable and secure electrical connection between the electrical conductor and the insulation displacement contact.
  • the conductor connection terminal can have a housing, in particular a housing made of insulating material.
  • the insulation displacement connection can, for example, be fixed to the housing, i.e. essentially immovable in relation to the housing of the conductor connection terminal.
  • the insulation displacement connection can form a counter bearing for the stamp.
  • the indefinite term “a” is not to be understood as a numeral. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component”. If angles are specified in degrees, these refer to a circular measurement of 360 degrees (360°).
  • Recognizable conductor terminal 1 has a housing 2 in which an insulation displacement connection 3 is arranged and fixed to the housing substantially.
  • the insulation displacement connection 3 has contact blades 30 to which an electrical conductor can be connected using insulation displacement technology.
  • the electrical conductor can be inserted into the housing 2 in a conductor insertion direction L.
  • the conductor connection terminal 1 has an actuating mechanism which has a manual actuating element 5 , a pressure piece 4 , an energy accumulator 6 and a plunger 7 .
  • the manual operating element 5 has a handle portion 50 on which the manual operating element 5 can be gripped and moved by the user, ie from the in figure 1 shown open position can be pivoted into a closed position explained below.
  • the handle section 50 is connected to a pressure section 51 of the actuating element 5 which is mounted so as to be rotatable about an axis of rotation.
  • the pressure section 51 has an eccentric actuating contour 52 via which an actuating force can be transmitted to the pressure piece 4 when the actuating element 5 pivots into the closed position. In this way, an actuating force generated manually on the actuating element 5 can be transferred to the pressure piece 4 .
  • the pressure piece 4 is coupled to the plunger 7 via the energy accumulator 6 .
  • the actuating force transmitted to the pressure piece 4 is transmitted to the plunger 7 via the energy accumulator 6 .
  • the stamp 7 is in Housing 2 is slidably mounted and is supported by one or more support springs 8 on the housing 2 or an associated component.
  • the stamp 7 is subjected to a force in the direction of the pressure piece 4 via the support springs 8 .
  • the actuating force is preferably aligned essentially perpendicularly to the direction L of conductor insertion.
  • the stamp 7 has a force absorption side 70, via which the force transmitted from the energy store 6 is absorbed on the stamp 7.
  • the stamp 7 On the side associated with the support springs 8, the stamp 7 has a support side 72, via which the stamp 7 is supported on the support springs 8.
  • a conductor receiving channel 71 is formed between the force receiving side 70 and the bearing side 72, into which the electrical conductor to be connected can be inserted.
  • the figure 2 shows the conductor terminal according to figure 1 in another sectional view with the actuating element 5 actuated, ie the actuating element 5 is in the closed position.
  • the pressure piece 4 the force accumulator 6 and the plunger 7 are pushed downwards via the pressure section 51, counter to the force of the bearing springs 8.
  • the inserted electrical conductor can then be pressed by the plunger 7 against the cutting edges 30 of the insulation displacement Connection 3 are pressed, so that an electrically conductive connection between the electrical conductor 9 and the insulation displacement connection 3 is produced. If the electrical conductor provided with insulation, for example, is pressed or pressed against the cutting edges 30 of the insulation displacement connection, the cutting edges penetrate the insulation of the electrical conductor 9 and contact the stranded wires or a solid conductor of the electrical conductor.
  • the support springs 8 When the actuating element 5 moves from the closed position to the open position, the support springs 8 also bring about a return of the plunger 7 to the starting position in accordance with FIG figure 1 and or figure 3 .
  • the electrical conductor 9 is thus also moved away from the cutting edges 30 via the conductor receiving channel 71 and can be removed from the conductor connection terminal 1 .
  • FIGs 3 and 4 illustrate once again the different positions of the individual components in the open position ( figure 3 ) and in the closed position ( figure 4 ).
  • the figure 5 shows an embodiment of a conductor terminal 1, except for the differences explained below the embodiment of figure 1 is equivalent to.
  • the stamp 7 is designed differently, with the support springs 8 also being arranged at a different position.
  • the stamp 7 has a radially projecting collar 73 on the force receiving side 70, via which the stamp 7 is supported on the support springs 8.
  • the support springs 8 can be supported in an area of the housing 2, for example.
  • the stamp 7 does not have the bearing side 72 that is spaced apart from the force receiving side 70 via the conductor receiving channel 71. It is conceivable that in this embodiment, too, the stamp can be designed with a conductor receiving channel similar to the conductor receiving channel 71 in FIG.
  • the figure 5 shows the conductor terminal, as in figure 1 , in the open position.
  • the figure 6 shows a to figure 2 Comparable sectional view in the closed position of the conductor terminal 1. It can be seen in the figure 6 That the stamp 7 in resting on the electrical conductor 9 area another difference to the embodiment of Figures 1 to 4 has, namely a conductor guide contour 74 present on the stamp 7, which extends like a groove or trough in the longitudinal direction or in the conductor insertion direction L of the electrical conductor 9 and thereby contributes in an improved manner to a centered contacting of the contact blades 30.
  • contours for example protruding edges or projections aligned transversely to the conductor insertion direction L, can be provided on the conductor routing contour 74 . In the closed position, these contours are pressed into the insulation of the electrical conductor 9, so that the conductor holding forces can advantageously be increased. It is of course possible to provide such a conductor guide contour 74 in the stamp according to the first embodiment of the conductor terminal.
  • FIGs 7 and 8 show analogous to the Figures 3 and 4 , the conductor connection terminal 1 in the open position ( figure 7 ) and in the closed position ( figure 8 ).
