Definitions

  • the invention relates to an insulation displacement terminal for contacting a non-stripped electrical conductor in a V-shaped contact area formed by mutually facing cutting edges of two clamping legs. It also relates to a handling device for inserting the conductor into the insulation displacement terminal.
  • a clamping slot is formed between two clamping legs, the mutually facing cutting edges of which run parallel to one another. Due to the resilient contact material, two conductors with different diameters can be clamped in the contact area for a double contact. However, the cross-sectional area for conductors to be contacted is restricted due to the geometry of the clamping slot forming the contact area.
  • EP 0 274 948 AI also discloses an insulation displacement connector with a V-shaped contact area.
  • the contact area is formed by cutting edges of rigid cutting legs which are set up in a circular arc and do not themselves have a clamping effect.
  • the conductor is inserted by being pressed in in the tapering direction of the V-shaped contact area, the mutually facing cutting edges of the cutting legs penetrate the conductor insulation up to the conductor core.
  • the conductor is clamped in the contact area by means of a lever arm.
  • the invention is based on the object of specifying a insulation displacement device by means of which electrical conductors are connected via a can be reliably contacted and securely clamped in the same way as the known insulation displacement clamps with a large cross-sectional area, preferably over a cross-sectional area of 0.5 to 2.5 mm 2 .
  • a handling device that is particularly suitable for inserting the conductor into the insulation displacement terminal is to be specified.
  • each cutting flank of at least one clamping leg is designed in such a way that the width of the contact surfaces formed by the cutting edges increases and decreases alternately with the tapering of the V-shaped contact area.
  • the clamping legs are not arranged to run parallel to one another, but instead are set inward at an angle. This causes the clamping force to self-amplify when a pulling force occurs on the conductor against the direction of adjustment of the clamping legs in the pulling direction of the conductor.
  • the angle of attack is expediently 0 ° ⁇ ⁇ 10 °.
  • each clamping leg and their cutting edges are arranged offset with respect to one another in the clamping and contact area. This results in a particularly reliable adaptation of the insulation displacement terminal to various conductor diameters with regard to the clamping and contact effect and cross sections achieved.
  • the cutting edges of each clamping leg are advantageously corrugated in a mirror image with respect to an axis of symmetry running along the ridge of the cutting edge. This results in particularly sharp-edged cutting areas and comparatively large contact areas along the cutting edge of the corresponding clamping leg.
  • the cutting flanks of the clamping areas formed by the varying width of the contact surface along the cutting edge and each adjacent to a cutting area are designed conically in the direction of the cutting edge and thus in the direction of the cutting edge.

  • the clamping legs are advantageously angled ends of legs of a U-shaped contact piece in the form of a contact plate, which is expediently the switching piece in a switching device.
  • An axial displacement of the conductor as a result of a wedge-shaped design of the transition region between the cutting and clamping region in the longitudinal direction of the cutting edge produces the contact force of the conductor end against the contact counterpart required for contacting.
  • the contact force can be increased by the fact that the contact or contact piece a bimetal is made. When heated, a further increase in the contact force is then achieved due to the bimetal effect.
  • the entire contact piece can also be box-shaped with rare walls made of bimetal. The end face opposite the insulation displacement area then expediently forms the additional contact point or area.
  • the clamping force for the different conductor diameters or cross sections is set via the position of the conductor in the contact area, i.e. about the position of the conductor in the gusset between the clamping legs arranged in a V-shape.
  • the conductor is guided when it is inserted into the V-shaped contact area by means of an additional handling part which picks up and stabilizes the end of the conductor to be contacted.
  • a handling device which has a passage opening on the bottom for receiving the conductor, on the underside of which a support arm provided with a bead is formed in an approximately L-shape. Opposite this, a recess is provided, which slides the clamping limbs of the insulation displacement clamp when the conductor is inserted.
  • the passage opening is continued in a stabilization area which is adjoined by a stop leg for the conductor end.
  • Cutting edges along the cutting edges of mutually V-shaped clamping legs of an insulation piercing contact make it possible to contact electrical conductors without stripping and without screws over a large cross-sectional area of approximately 0.5 to 2.5 mm 2 regardless of the thickness of the conductor insulation and the insulating material. Solid, long-distance or multi-wire conductors can be reliably contacted and be securely clamped. The handling when inserting the conductor in the contact area can be done with simple tools.

Abstract

L'invention vise à permettre, avec un dispositif perce-isolant (1) sans vis, une mise en contact fiable d'un conducteur électrique (2) non dénudé, sur une zone de section transversale importante comprise par exemple entre 0,5 et 2,5 mm2 dans une zone de contact (6) en V formée par des arêtes coupantes (10, 11), se faisant face, de deux bras de serrage (4, 5). A cet effet, les flancs coupants (11, 12) des arêtes coupantes (10, 11) présentent une forme ondulée. La largeur (b, b', b'') des surfaces de contact formées par les arêtes coupantes (10, 11) augmente et diminue en alternance dans le sens de rétrécissement (14) de la zone de contact (6).
