Definitions

  • the invention relates to an insulation displacement contact the non-stripped end of an electrical conductor the features of the preamble of claim 1.
  • a cutting clamp known from DE 44 03 278 A1 from a sheet-shaped contact material is a clamping slot between two contact legs are formed, their facing each other Cutting edges run parallel to each other.
  • the resilient contact material can be used for double contacting two conductors with different diameters be clamped in the contact area.
  • the diameter range of the However, the conductor to be contacted is due to the geometry of the clamping slot forming the contact area.
  • EP 0 274 948 A1 also discloses an insulation displacement terminal known with a V-shaped contact area.
  • the contact area is set up in a circular arc due to its cutting edges.
  • the Cutting legs are rigid and have no clamping effect.
  • When inserting the conductor by pressing in the direction of taper of the V-shaped insertion area penetrate the mutually facing cutting edges of the cutting legs Conductor insulation up to the conductor core.
  • the clamp fixation of the Conductor in the contact area is made using a lever arm.
  • the range of suitability is also with this known insulation displacement clamp for conductors to be contacted with different Diameters only limited.
  • the insulation displacement contact element is made up of four identical clamping clips, each a substantially rectangular sheet metal tab exhibit. These each have two insulation piercing arms, which has a V-shaped cutting area and is attached to it then enclose the clamping slot of constant width. The width of the clamping slot is based on the diameter of the conductor wire to be contacted.
  • the V-shaped cutting area has a profile to the required cutting force and thus on the insulation displacement arms exerted transverse force when cutting through the insulation to keep the conductor wire low.
  • In the known from this Insulation displacement terminal is a contacting of conductors with different Conductor diameters not possible.
  • the invention has for its object to provide an insulation displacement terminal of the type mentioned, which allows contacting electrical conductors over a large cross-sectional area without stripping. Conductor cross sections between about 0.5 and 2.5 mm 2 are intended. Both solid and fine-stranded electrical conductors should be able to be contacted here. Furthermore, a high pull-out strength comparable to that of a screw terminal should be guaranteed. Finally, the insulation displacement clamp should be operable with a simple tool, for example a screwdriver, both during assembly and disassembly.
  • Insulation displacement clamp has a special elasticity, so that the contacting of conductors with different cross sections is possible.
  • the insulation displacement clamp in the manner of resilient pliers, the possibility of one cross-sectional control of the cutting and / or Clamping forces created. In principle, it depends on the outside diameter a specific stop by the conductor himself available that can be used in several ways can. This is once in the version as a "moving insulation displacement" possible with the leader in or on a recording inserted or put on and the insulation displacement contact is shifted towards the conductor.
  • This version can be a second connection that only serves for clamping according to claim 2 to a further conductor part, e.g. to a switching contact of a command device can be made.
  • the closing pressure of the resilient forceps effect can be from Control the ladder depending on the position. That is about the contour of the Conductor part and / or the terminals or the enclosing Housing possible.
  • the insulation is in the cutting area effective on the conductor of the conductor. This happens in a particularly efficient way Cut through a serrated edge (Claim 7), the contact introduction of the non-stripped conductor without excessive pressure on the Conductor core causes a pulsating, dynamic cutting and avoids disadvantageous notching of the conductor.
  • the actual clamping contact takes place between the two in essentially parallel foot edges of the Y shape in that there formed terminal contact area.
  • the clamp expediently consists of bimetal (claim 16).
  • she advantageously results from a single, one-piece Bimetallzuites. This will e.g. the elasticity of Steel combined with the conductivity of aluminum.
  • the invention Design of the insulation displacement clamp causes Heating due to high current density at the contact point or at the contact points instead of a decrease in contact pressure and an associated further increase in Contact resistance the opposite. Because it will the different coefficients of thermal expansion make sense of the elements of the bimetal, i.e. bimetal effects exploited.
  • the insulation displacement terminal contains for contacting the non-stripped End of an electrical conductor, not shown two contact legs facing each other with their side edges 1, 2 3,4 with an insulation displacement gap 5 between them the shape of the outline include an upside down Y. They form an upside-down V-shape the insertion opening 6, which are in relation to one another and between them head edges 7, 8 of the Y-shape delimit the conductor insulation penetrating cutting area.
  • the one another essentially however, form parallel foot edges 9, 10 of the Y shape the terminal contact area.
  • the head edges 7, 8 of the insertion opening 6 or the Y shape are one according to the type of cutting Household knife corrugated in its longitudinal direction.
  • the mutually facing end faces 11, 12 of the head edges 7,8 are bevelled in such a way that they are at the receiving space 13 for the inside of the conductor facing one Form acute-angled cutting edge 14, 15.
  • Each cutting edge 14, 15 forms thereby a positive clearance angle with the adjacent one and thereby with its outside 16 or 17 from the insertion opening 6 recessed end face 11 or 12.
  • the contact leg 3.4 are in the area of the cutting edges 14.15 in about a common level.
  • That of the contact legs 3, 4 in the area of the cutting edges 14, 15 delimited plane containing the insertion opening 6 is facing away from the receiving space 13 for the conductor end Side out to form an obtuse angle 23 inclined with the terminal contact area 24.
  • a slit Transition area 25 Between the insertion opening 6 and the terminal contact area 24 lies in the plane of the insertion opening 6 a slit Transition area 25.
  • the transition area 25 they are each other facing end faces 11, 12 and 18, 19 of the contact legs 3.4 around an axis running approximately in its longitudinal direction wound in such a way that their transition edges forming the transition gap a ridge-like transition from the recording room 13 for the conductor end facing inner cutting edges 14, 15 of the cutting area to that of the receiving space 13 for the outer edges 26, 27 of the terminal contact area facing away from the conductor end 24 manufacture.
  • This transition is seamless.
  • the receiving space 13 for the conductor end has the Contact limbs 3.4 facing away from a contact stop for the insulation-free conductor end.
  • This contact stop is in the embodiment by at least one of both enclosing a terminal contact slot between them Clamping contact jaws 28, 29 formed.
  • the insulation piercing consists of a one-piece bimetal blank. It is one of the receiving space 13 for the conductor end surrounding U-shaped base body formed, the U-leg 30,31 form the side walls of the base body. On one side edge each of the two side walls, in the case of the FIG 1-3 at their front side edge are the contact legs 3.4 molded. The other, in the figures rear side edge carries a clamping contact jaw 28 and 29, respectively Bottom web 32 as a U-web forms together with the U-legs 30.31 the U-shape of the base body. This U shape of the The base body is opposite the U-web 32 Lock 33 of the free ends of the U-legs 30,31 to one the receiving space 13 for the frame surrounding the conductor end further training.
  • This lock 33 is in one Swivel recess 34 engaging swivel plate 35 articulated designed such that a certain mobility of the U-legs 30.31 against each other is possible. That agility is further by an elastic design of the U-web 32nd supported between the two U-legs 30.31.
  • a non-stripped conductor is used with its cut end transverse to its longitudinal direction in the direction of the arrow the insertion opening 6 shifted.
  • the head of the line is there into the receiving space 13 and against a contact stop in the form e.g. at least one of the two clamping contact jaws 28.29.
