Definitions

  • the invention relates to a wire support, in particular for capacitive protective fences, which has a rod and an insulated end.
  • wire supports to accommodate electrical lead wires. These can have a rod and, at a free end of this rod, an insulating body in which the wire is fastened, e.g. for electric pasture fences.
  • wire supports are also used on protective fences.
  • wire supports are arranged on protective fences which are intended to prevent unauthorized entry.
  • the wires stretched in parallel as capacitance electrodes are supported with such supports.
  • they In order to be able to mount wire supports easily and to use them in a variety of ways, they have to be specially designed.
  • the object of the invention is therefore to provide a wire support which is to be changeable in its length, which allows quick assembly and which is intended to enable simple wire fastening.
  • a wire support which is characterized in that the rod has a fastening clamp at one end and at the other end an insulating tube which can be moved telescopically over the rod, the insulating tube being free End has a notch and a collar on its other end.
  • the length of the support can be adapted to the respective requirements.
  • the notch in the insulating tube allows the wire to be supported to be easily accommodated. So that the insulation cannot be damaged by the contact edges in the notch when using an insulated wire, the contact edges can be rounded to the outside in an advantageous manner.
  • a bore can be provided in a development of the innovation perpendicular to the notch of the insulating tube. If the wire is in the notch, an expanding rivet or the like can be inserted through the hole. The bore can be arranged so that the wire has a slight play in the notch between the contact edges of the notch and the expanding rivet and thus remains longitudinally movable.
  • the adjusting ring arranged on the insulating tube can expediently have an adjustable threaded pin.
  • the wire support 1 shown in FIG. 1 has a rod 3, at one end of which a fastening clamp 2 is arranged. With this fastening clamp 2, the wire support 1 can be fastened, for example, to a pole of a fence, not shown here.
  • the insulating tube 4 On the free end of the rod 3, the insulating tube 4 is arranged telescopically with an adjusting ring 5.
  • the adjusting ring 5 has a locking screw 5a perpendicular to the longitudinal axis of the insulating tube 4.
  • the insulating tube 4 has a notch 4a at its free end. The wire can be placed in this notch 4a.
  • the notch 4a has roundings on the outside of its contact edges 4b for the wire. This is to prevent damage to the wire insulation.
  • a bore 4c extending through the insulating tube is provided on the insulating tube 4 perpendicular to the notch 4a. For example, an expanding rivet can be inserted into this bore 4c.
  • FIG. 2 The side view of the wire support 1 according to FIG. 1 is shown in FIG. 2 viewed from the front.
  • the notch 4a of the insulating tube 4 can also be seen here.
  • the bore 4d leading perpendicularly to the notch through the insulating tube is shown in dashed lines.
  • a part of the insulating tube 4 of the wire support 1 is shown in FIG. 3 viewed from above.
  • the insulating tube 4 is provided with the notch 4a at its free end.
  • the bore 4c runs perpendicular to this through the insulating tube 4.
  • the contact edges 4b in the notch 4a are rounded towards the outside, as shown in FIG. 3 and FIG.
  • wire supports 1 which are used, for example, for a capacitive protective fence.
  • a tensioned wire 17 is fastened to the fence pole 6 with an insulator 8. If the wire 17 is to be guided to a junction box 9 attached to the mast, the Lead wire 7 are guided over a wire support 1 and supported thereon without the length of the lead wire 7 also being changed when the tensioned wire 17 is changed in length.
  • the wire support can be mounted on the mast 6 at a certain distance above the wire 17 and the insulator 8. For example, it can be attached to a round mast using pipe clips 2.
  • the connection ⁇ wire 7 is from the insulator 8 vertically upwards to the support 1 and from there at an angle to the junction box 9.
  • the wire support 1 can be adjusted and locked to the necessary length so that the connecting wire 7 lies in the notch 4a of the insulating tube 4 and is supported.
  • the same wire supports 1 can be used to support the wire 17 stretched relatively close to the ground (FIG. 4). These must be attached to the floor.
  • the insulating tube 4 is pushed over the rod 3 to the fastening clamp 2 in order to obtain a short wire support 1.
  • the wire 17 lies in the notch 4a of the insulating tube 4.
  • an expanding rivet or the like can be inserted through the bore 4c of the insulating tube 4.
