Definitions

  • the present invention relates to those electrical connectors of the type with two bodies provided with clamping elements fit to clamp the main conductor and the secondary conductor to electrically connect one to the other.
  • Such connectors are usually used as shunt, junction or terminal elements for insulated or naked, multiple or single-wired conductors.
  • Some connectors are known, a body of which is provided with a first and a second series of teeth or metallic top lands electrically connected among them. To the above described body another body is clamped, by suitable means, provided with insulated elements, for example plastic material, in such a way that a main conductor is laid down between the first series of teeth and the insulated elements of the second body and so likewise the derived conductor is laid down between the first body second series of teeth and the further insulated elements provided on the second body.
  • the second body insulating elements are set in proper position, in such a way that when the second body is clamped on the first, such insulated elements come to set out in correspondence with the first and the second series of metallic teeth respectively.
  • Figg. 1 and 2 is shown, as an example, an electrical connector formed by two bodies 1 and 2, provided respectively with tongue 3 that goes to insert into slot 4 when the two bodies are mounted one against the other, clamping the main conductor 5 and the derived conductor 6 by means of clamping elements 7. Said bodies 1 and 2 are clamped one against the other by screwing the nut 8 on the screw 9 provided by the head 10 placed below the body 1. The screw 9 is through across a hole 11 made into bodies 1 and 2, as one can see in Fig.2.
  • the conductors may be indifferently naked or insulated.
  • the conductors 5 and 6 are insulated by means of a sheath 12.
  • the elements 7 consist of the upper blades 13 and lower blades 15.
  • the upper blades 13 made of an insulating material being part of body 2 consist each of a pair of curved sectors 14 tapered blade-shaped on the side where they receive the conductors 5 and 6 as one can see in Figg.3 and 4.
  • the lower blades 15, fixed to the body 1 and for example of copper, aluminum or Zn + Al + Mg alloy, consist likewise of a pair of curved sectors 14 tapered blade-shaped, that set opposed to the upper blades 13 in a way such as to clamp the conductors between the pairs of curved sectors 14 respectively of blades 13 and 15.
  • the metallic blades 15 in contact respectively with the conductors 5 and 6 are electrically connected by the conductors 16, as illustrated in the Figg.1 and 2.
  • the upper blades 13 made of plastic material are machined enbloc with their own body 2 formed of plastic material by the die-casting technique.
  • the nut 8 is tightened by an usual spanner in such a way as to occur the tightening of the above said conductors 5 and 6 between the clamping elements 7.
  • Said curved sectors 14 have a curving radius suitable to the various dimensions of the conductors and tapered blade-shaped or not damaging the conductors and for their perfect self-centering.
  • each curved sector 14 both of metal and of insulating material, is slightly spaced from the adjacent sector by an entity 17, as one can see in Fig.3.
