Definitions

  • the invention relates to the domain of the connection of at least one electric branch line with an electric main line, for example, a cable core.
  • the circlip capable of simultaneously branching three or more conductors and the separate branch clip.
  • the circlip has the following drawbacks: the cable insulation of all conductors is removed and/or damages in the same zone. This gives rise to very short creepage ways for moisture, for example, of the order of a few millimeters, so that a high-quality insulator to be applied in the liquid state is required to repair these damages. If cable insulating material such as PE, XLPE or PTFE is used, no liquid insulating material is available capable of definitely repairing cable damage. Moreover, the circlip causes a relatively large thickening at one place on the cable, so that relatively voluminous sleeves are required. With some types of circlips it is, moreover, not possible to determine which connection is first established. A further disadvantage is that some circlips are suitable only for one cable diameter.
  • circlips require the removal of the so-called filling wire from the cable, special precautions for the test cores and strong bending of the cores at the location of the circlip. It is finally noted that circlips frequently have cavities into which the liquid insulating material cannot penetrate.
  • a disadvantage of the known branch clip is that an usually U-shaped bracket has to be arranged between the cores of an usually multicore main cable in order to ensure sufficient strength and resilience. Additional space is required for fastening such a bracket. Therefore, the known branch clips are usually provided with additional spring elements. In both designs the branch clip is relatively large. The application of such a branch clip is, if possible, even more troublesome than that of a circlip.
  • the invention has for its object to obviate the disadvantages of the known branch clips and provides to this end a branch clip of the aforesaid kind which is characterized by a clip body having two clamping jaws each having a tail piece and at least one bridge piece interconnecting said clamping jaws at the transition between the clamping jaws and their tail pieces so as to be rotatable about parallel axes and by a connecting block that can be disposed between the tail pieces and that has at least one clamping member for connecting the branch conductor and at least one tapped hole with a branch bolt directable to the main conductor, said connecting block arranged in place between the tail pieces being coupled with the tail pieces during tightening of the branch bolt in a manner such that the clamping jaws are clamped against the main conductor.
  • a layer of insulating material can be interposed between the connecting block and the clamping body.
  • a very advantageous variant exhibits the particularity that after the disposition of the connecting block between the tail pieces of the clamping jaws said tail pieces of the clamping jaws are inclined away from and towards one another respectively, viewed away from the rotary axes, and that at their free ends the tail pieces have end parts bent over across the connecting block.
  • the or each bridge piece is made from spring material.
  • the branch clip 1 serves to connect two electric branch conductors, one of which is designated by reference numerals 2, to an electric main conductor, in this embodiment a cable core 3.
  • the branch clip 1 comprises a clip body 4 provided with two clamping jaws 7,8 each having a tail piece 5 and 6 respectively and a resilient bridge piece 26,11 interconnecting said clamping jaws at the transition between the clamping jaws 7,8 and their tail pieces 5,6 respectively so as to be rotatable about relatively parallel axes 9,10.
  • the branch clip 1 furthermore comprises a connecting block 27 which can be disposed between the tail pieces 5,6 and which has two bores 12,13 receiving screws 14,15 for connecting the branch conductors (Fig.2 shows the branch conductor 2) and which has a tapped hole 16 being directed at right angles to the cable core 3 and having a branch bolt 20, said connecting block 27, after having been arranged in place between the tall pieces 5,6, being coupled with the tail pieces 5,6 during tightening the branch bolt 20 in a manner such that the clamping jaws 7,8 are clamped against the cable core 3.
  • a connecting block 27 which can be disposed between the tail pieces 5,6 and which has two bores 12,13 receiving screws 14,15 for connecting the branch conductors (Fig.2 shows the branch conductor 2) and which has a tapped hole 16 being directed at right angles to the cable core 3 and having a branch bolt 20, said connecting block 27, after having been arranged in place between the tall pieces 5,6, being coupled with the tail pieces 5,6 during tightening the branch bolt 20 in a manner such that the clamping jaws 7,8 are clamp
  • the cable core 3 has a sector-shaped design and is provided with an insulating sheath 17.
  • the shape of the clamping jaws 7,8 matches the shape of the core 3 as is shown in fig.2
  • the active surface of the clamping jaws 7,8 facing the cable core 3 is provided, in this embodiment, with a profile of ridges 18,19 in order to ensure a satisfactory frictional contact.
  • a layer of insulating material designed in the form of a cap 22 of insulating material.
  • the tail pieces 5,6 have end parts 24 and 25 respectively bent over across the connecting block 27.
  • Fig.3 shows a variant in which the clamping jaws 7' and 8' are provided at their free peripheral edges with bent-over rims 28 and 29 respectively that can be hooked around the cable core 3. These rims 28 and 29 are relatively off-set and fit in this embodiment in recesses 30,31 in the clamping jaws 7' and 8' respectively.
