Definitions

  • the invention relates to a clamp connector in a chamber made of insulating material for stripping-free connection of at least one switching wire of communications technology protected by an insulating sheath of a given thickness.
  • the invention has for its object to provide a clamp connector of the type mentioned, which allows to contact the or the jumper wires without the above-mentioned effort and avoiding their destruction; it should be possible to set and loosen the jumper wires several times if necessary.
  • a type of connection in which the insulated jumper wire is inserted into a cutting, scissor-like receptacle is not desired, since the risk of completely severing the jumper wire is too great with this type of installation (DE-PS 2 142 850).
  • the invention solves this problem by the characterizing features of claim 1.
  • the particular advantage of the clamp connector according to the invention is that the contact wires to be contacted are safely contacted without the need for special tools, devices or special dexterity of the assembly personnel; the clamp connector according to the invention is therefore particularly suitable for use on site at construction sites.
  • Each clamp connector consists of two contact legs arranged in a chamber made of insulating material, at least one of which is made of a metallic material with good electrical conductivity.
  • the contact leg 2 which is rigidly arranged in a housing (not shown) and is electrically conductively connected to a transfer element (not shown).
  • a contact leg 3 designed as a spring is provided, which rests under pressure on the contact leg 2.
  • the contact pressure comes from a leg 31 of the spring, which is supported on the housing, not shown.
  • the two contact legs 2 and 3 have a longitudinal extension in the direction of the arrow 4 for receiving a jumper wire 5, see FIG. 4.
  • a nose 21 of the contact leg 2 limits the jumper wire length leading into the clamp connector 1.
  • the contact leg 2 carries a sharp-edged knife 6, which is arranged transversely to the direction of the arrow 4.
  • the knife height 7 (Fig.3) is designed so that after inserting an insulated jumper wire into the clamp connector 1, the sheath 51 (Fig.4) is cut due to the contact pressure of the spring 3 and the knife just into the electrical conductor 52 of the Jumper wire 5 penetrates. This creates a low-resistance connection between the jumper wire and the contact leg 2 without the jumper wire being notched so strongly that there is a risk of a wire break. Since the contacting of the electrical conductor (s) takes place exclusively via the contact leg 2, any suitable spring material, including those with poor conductivity, can be used for the spring. Plastic can also be used as the spring material.
  • the contact leg 2 with the knife 6 can advantageously be made of beryllium bronze. So that the sharpness of the knife 6 is not impaired in any case, an embossment 32 or a corresponding hole is provided on the spring 3 for receiving the knife 6 when the clamp connector is not fitted.
  • the contact leg 2 according to Figure 2 shows a section Knife 6, which is torn out of the material during the manufacturing process of the contact leg 2.
  • FIG. 3 shows a contact leg 2, in which two further knives 61 and 62 are provided in addition to the knife 6.
  • the rear end 22 of the contact leg 2 is shown broken off, because the design of this end is of secondary importance for the understanding of the clamp connector 1.
  • the actual design of the contact leg depends on whether the respective clamp connector 1 is part of a solder bar, a terminal block or a multi-pin connector.
  • Figure 5 shows a terminal block 8 made of insulating material with four chambers 81, 82, 83 and 84.
  • Each of the chambers, for. B. the chamber 81 contains a clamp connector 40 with a jumper wire 501.
  • the individual springs, for. B. the spring 10, an actuator 9 designed as a lever or rocker is assigned, which is used to open the relevant clamp connector before a wire insertion. By pressing the actuator 9, the biased spring 10 is compressed so that the jumper wire 502 can be easily inserted. After releasing the actuator 9, a connection is produced as shown in the arrangement according to FIG. 4.
  • the clamp connector is provided with an adjusting screw 11 for fixing and contacting one or more electrical jumper wires 50 instead of a spring.
  • the fixed contact leg 20 is represented by the yoke of a U-shaped body, between the legs of which the movable contact leg 30 is guided parallel to the yoke.
  • This contact leg is adjustable by the adjusting screw 11 in the longitudinal direction of the legs of the U-shaped body; due to its design as an angle, tilting in the U-shaped body is prevented when the control barrier is tightened.
  • the set screw 11 is supported in a cross member 12 which connects the leg ends of the U-shaped body to one another.
  • Both contact legs 20 and 30 have protruding knives 60 on their pressing surfaces facing one another, which, as in the exemplary embodiments of the invention explained above, run essentially transversely to the longitudinal direction of the jumper wire 50 and are dimensioned such that they cut the sheathing of the jumper wire when the adjusting screw is tightened and just penetrate into the jumper wire.
  • the use of several knives guarantees a very low-resistance connection between the jumper wire and the clamp connector.
  • the particular advantage of the clamp connector according to FIG. 6 is that it can be used, if necessary, for contacting jumper wires of different diameters with the same insulation thickness.
  • both single and multi-wire jumper wires can be contacted, and if necessary, several jumper wires of the same diameter can also be jointly fixed and connected in a clamp connector.
