Definitions

  • the invention relates to a connector or terminal for an overhead cable, comprising a clamping bolt or screw and at least three connector blocks, which are pressable by the clamping bolt or screw towards each other and which connector blocks provide therebetween two intermediate spaces for receiving wires on either side of the middle connector block.
  • the connectors capable of piercing a wire insulation have included two blocks, between which is a single intermediate space for joining together a single pair of wires in such a way that the connector blocks establish an electrical contact between the wires.
  • the assembly of the invention must provide such a connector which is capable of connecting more than one pair of conductors or wires.
  • the functionally identical components are designated with the same reference numerals, although such components may be structurally different from each other.
  • metallic connecting pieces 10 which in the embodiments of figs. 1, 5 and 9 are short in the direction of wires and a plurality of which are set in succession in the direction of wires, the separate connecting pieces 10 being bound together with a lacing strip 11 which can be made of moulded plastics or a soft metal, with the connecting pieces 10 embedded therein.
  • the connecting pieces 10 are provided in the direction of wires with short serrations, a plurality of which are set in succession in the direction of wires.
  • the embodiments of figs. 1-10 comprise three connector blocks or connector platens1, 2, 3, which are pressable towards each other by means of a clamping bolt 8 or a clamping screw 8' extending through these blocks or platens.
  • the connector blocks 1, 2, 3 are preferably made of an insulating material (hard plastics) and a stack of blocks constituted by the successive connector blocks 1, 2, 3 is placed between press plates 6, 7.
  • the press plates 6, 7 can be made of a metal or hard plastics. If made of hard plastics, the press plates 6 and 7 can be made in a single piece with the outer connector blocks 1 and 3.
  • the connector blocks 1, 2, 3 constitute therebetween two intermediate spaces for receiving wires on either side of the middle connector block 2.
  • the middle connector block 2 is provided with one or more metallic connecting pieces 10, extending through the block 2 in a direction perpendicular thereto.
  • the teeth or serrations of the connecting piece 10 extend into wire-receiving gutters present in the intermediate spaces to a distance sufficient for the teeth to penetrate through the wire insulation as the connector blocks 1-3 are clamped towards each other.
  • the connecting pieces 10 establish an electric connection between two wires on top of each other.
  • the connector is only intended for connecting two wires.
  • the outer connector blocks 1, 3 are coupled with hinge links 9 to the middle connector block 2.
  • the outer connector blocks 1, 3 are coupled to each other with a hinge link 9'.
  • this embodiment has its outer connector blocks 1, 3 provided with serrated connecting pieces 12 interlinked by way of a wire or conductor 14.
  • each intermediate space between the connector blocks 1, 2, 3 is provided with take-up recesses for two wires, i.e. the connector is designed for two pairs of wires.
  • the middle connector block 2 is provided with metallic connecting pieces 10 on both sides of the clamping bolt 8 or the clamping screw 8'. Each intermediate space is provided with two wires.
  • FIG. 5 The embodiment of figs. 5 and 6 further illustrates on the right-hand side of fig. 5 that the outer connector blocks 1, 3 are also provided with serrated connecting pieces 12' interlinked by way of a wire assembly 14'.
  • Figs. 7 and 8 depict the use of a moment screw fitted with a moment head 8" for securing a proper clamping.
  • the embodiment of figs. 11 and 12 differs from those described above principally in the sense that the number of connector blocks 1, 2, 3, 4, 5 is five and these are stacked on top of each other, the connector functioning as a joint for four pairs of wires. Therefor, two connector blocks 2 and 4 are provided with metallic connecting pieces 10 on either side of the clamping bolt 8.
  • the embodiment of figs. 9 and 10 differs from the others in the sense that the clamping bolt is replaced with a clamping screw 8', which is engaged in a threaded hole extending through a press plate 7 and a bar 7" adapted thereto.
  • the number of clamping bolts or screws 8, 8' is typically 1 or 2.
  • the connector is not limited to the foregoing exemplary embodiments.
  • the metallic connecting pieces 10 may be in the form of screws having high and sharp thread edges.
  • the connector blocks 2 and 4 are provided with laterally opening threaded holes, through which the screws can be laterally threaded inside the block, the thread edges of the screws cutting through the conductor insulation and establishing an electric connection between the wires present on the opposite sides of the block 2, 4.
  • the embodiment shown in figs. 13-15 differs from those described above in the sense that there are metallic connecting pieces 15, 16 and 15, 16' extending laterally of the blocks 1, 2, 3 between adjacent take-up recesses, the connecting pieces establishing an electric connection each time between the two wires present in the same intermediate space.
  • the middle connector block 2 is provided on either side thereof with a single connecting piece 16,16' and the outer connector blocks 1, 3 are also provided with connecting pieces 15, 15' on the internal sides thereof.
  • the conductors included in a pair of conductors present in the upper intermediate space on either side of the screw 8 will be connected to each other by means of the connecting pieces 15 and 16.
  • the conductors or wires present in the lower intermediate space on either side of the screw 8 will be connected to each other by means of the connecting pieces 16' and 15'.
  • the ends of the connecting pieces are provided with teeth piercing through the wire insulation.
  • the conductors or wires of each pair of conductors will be connected to each other every time by means of two connecting pieces.
  • the lower connecting pieces 15', 16' are surrounded by a packing 17, from which protrude the teeth of the connecting pieces and which compresses against the wire insulation surface around the junction so as to establish a watertight joint.
  • the respective packings 17 may also be arranged around the upper connecting pieces 15, 16.
  • the connector blocks 1, 2, 3 are provided with take-up recesses for the connecting pieces for retaining the connecting pieces in position.
  • Fig. 13 shows boxes 18, 19 present on one side of the connector as extensions for wires to be connected for protecting the free ends of wires extending a small distance from the junction.
  • Fig. 15 illustrates the way of using a connector of the invention for interconnecting also wires or conductors of unequal diameters.
  • the outer connector blocks 1 and 3 are capable of tilting by virtue of an arcuate design of the outer contours thereof, which matches the arcuate design of the mating surfaces of the press plates 6' and 7'.
  • Fig. 14 visualizes springs 20 present between the connector blocks 1, 2, 3 for forcing the connector blocks apart from each other to keep the intermediate spaces open for a convenient insertion of the wires.
  • the springs 20 are preferably coil springs set around the screw 8.
  • the press plate 7' carries also provided a correspondingly designed bar 7" which is provided with a threaded hole for the clamping screw 8.
  • the number of such connectors required for connecting the four conductors of a three-phase line is just two, while in the past the required number of such connectors has been four.
