Definitions

  • insulation displacement technology has been widely used in practice for solid wires. The reason for this is a little labor-intensive contacting, which can optionally be carried out fully automatically.
  • insulation displacement contacts are characterized by a higher electrical safety than the conventional screw.
  • the solid wire which is not isolated from the insulation, is pressed with a tool into a insulation displacement slot.
  • the insulation is cut by the slot edges.
  • the spacing of the slot edges is matched to the diameter of the solid wire in such a way that a desired contact pressure is generated without the solid wire being cut off.
  • the actual contact surface is relatively well sealed by the remaining insulation against environmental influences. With a corrosion is either not at all or only in a long period expected.
  • the clamping conditions between the slot edges and the solid wire are very stable mechanically and long-term.
  • the contact force also changes when the insulation creeps over time.
  • the GB 20 79 070 A shows a insulation displacement contact for stranded wires to power plugs.
  • longitudinally slotted sleeves are provided, which are placed on the insulated wire strands.
  • the longitudinally slotted sleeve can be created in this way two jaws, which lie laterally next to the wire insulation. Ribs inside the longitudinally slotted sleeve point towards the insulation.
  • the assembled arrangement of sleeve and stranded wire is inserted into a receiving pocket made of insulating material, with the longitudinal slot ahead. In the pocket protrudes a sheet-like cutting contact whose broad side is aligned parallel to the longitudinal axis of the wire or the sleeve.
  • the cutting contact penetrates between the wires of the strand and makes contact here.
  • the sleeve is compressed in the pocket, so that the ribs completely penetrate the insulation or largely penetrate.
  • the sleeve provides a lasting good contact force between the stranded wires and the separating contact.
  • the new arrangement is a modified form of insulation displacement contact for solid wires.
  • the new arrangement has two support surfaces delimiting a slot.
  • the support surfaces are substantially parallel to each other and have a distance which is matched to the diameter of the strand bundle to be contacted.
  • the support surfaces are designed at their free ends so that they penetrate the wire insulation when contacting.
  • At least one mandrel is provided, which penetrates into the strand to press the individual stranded wires against the laterally and tangentially extending side cheeks next to the strand.
  • the biasing force that generates the contact force is thus generated to a very large extent due to the interaction between the mandrel and the side cheeks. Since the stranded wires are stranded together, so have a blow, the strand, which is divided by the mandrel into two sections, yet held together and can not spread like a loose pile in the gap between the mandrel and the adjacent side cheek, and although in the direction parallel to the longitudinal extent of the gap. Such a free distribution would cause a reduction of the contact force.
  • the new arrangement no longer relies so much on the holding effect of the wire insulation. Even if the wire insulation gives way or creeps, the stranding of the strand in conjunction with the driven mandrel ensures that the stranded wires are held with sufficient contact force on the metallic contact surfaces.
  • both parts are electrically connected to provide the largest possible contact area and a low contact resistance.
  • the new type of contact has such a high degree of reliability that it is suitable as an "EX-e" contact within the meaning of the explosion protection protection regulations.
  • the use of a simple mandrel without the abutment with the two side cheeks does not meet these protection requirements.
  • the support surfaces may be flat surfaces on their side facing the strand, which are particularly easy to manufacture. A crowning is also possible.
  • the cutting edges at the respective end can also run at right angles thereto, which facilitates penetration into the insulation, in particular prevents a peeling action.
  • the resulting cut surfaces in the insulation lie in a common plane, which is largely perpendicular to the longitudinal axis of the strand. These blades can converge like a funnel in the direction of the support surfaces, which facilitates the centering and avoids damage to the strand.
  • the support surfaces can be made prismatic on their leading end when contacting.
  • Those areas of the support surfaces which lie next to the strand after the final contacting are preferably parallel to one another.
  • the support surfaces may be flat surfaces, or slightly cambered in the direction of the strand.
  • the support surfaces may be limited by sharp or rounded edges.
  • the mandrel which is pressed into the strand to conform to the strand in the region between the support surfaces, may have the shape of a cylindrical pin which is provided with a tip at the penetrating end. It is also possible that the mandrel has a rectangular cross-section, which is provided at its end penetrating into the strand with a prismatic tip conformation.
  • the contact can be improved if more is used as a mandrel which penetrates through the insulation into the actual strand strand.
  • the mandrels are then lined up along the strand next to each other. Conveniently, there is at least one mandrel between the two support surfaces.
  • the two other mandrels can be mutually pivoted relative to the central mandrel to prevent the adjacent mandrels from creating a continuous gap in the strand of strands.
  • the mandrels can be formed on a common punched part, which considerably simplifies the production. A particularly permanent contact is achieved when an abutment is present between the support surfaces, against which the strand is pressed with the insulation.
  • a corresponding support surface can then also be provided next to the mandrel.
  • This support surface may be formed like a blade to allow penetration into the insulation to create a direct contact between the strand and the support surfaces.
  • the mandrel does not necessarily penetrate between the two support surfaces in the strand. He may also be offset from the support surfaces a little way in the longitudinal direction of the strand bundle. As a result, if necessary, larger tolerances are possible and there is also the possibility that sharp-edged ending support surfaces easier to cut a possible oxy-skin on the stranded wires.

  • the individual stranded wires 11 of the strand 8 are stranded together in a known manner, so that there is an approximately rotationally symmetrical strand strand within the wire insulation 9.
  • the Schneiklemmutton with which each cable core is contacted is composed of a soldered to the circuit board 1 mandrel 12 and a counter or abutment 13 together.
  • the mandrel 12 is in the embodiment according to Fig. 1 a rotationally symmetrical elongated body with a diameter 20% to 50% smaller than the diameter of the strand 8. At its free end it is provided with a conical tip 14. The rear end of the mandrel 12 merges into a cylindrical shaft 15 of significantly larger diameter. At the transition point between the shaft 15 and the mandrel 12, a frustoconical shoulder 16 results.

  • the width of the gap is slightly, about 0.1 to 0.2 mm larger than the diameter of the strand 8 at a wire diameter of about 0.7 mm.
  • the base part 22 is composed of a rounded back 23 and two of the back 23 outgoing legs 24 and 25 together.

  • the support surface 26 merges with each other parallelelen sharp edges 27, 28 in narrow side surfaces 29, of which only one can be seen because of the representation.
  • the width of the side surface 29 corresponds to the material thickness of about 0.5 to 0.7 mm.

Therefore, there is no need that the abutment 13, which sits in the lower socket 34, is again additionally electrically connected to the circuit board 1. Nevertheless, it is also conceivable to use the support surfaces 26 to increase the contact surface.
