Definitions

  • the invention relates to a wire support, in particular for capacitive protective fences, which has a rod and an insulating body.
  • wire supports for receiving electrical lead wires. These can have a rod and at one free end of this rod an insulating body in which the wire is fastened, e.g. B. 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 at one end a mounting bracket and at the other end as an insulating body an insulating tube which can be moved telescopically over the rod, the insulating tube having a notch on its free end and on its other End has a collar.
  • the length of the support can be adapted to the respective requirements with the telescopic insulating tube.
  • the notch in the insulating tube allows the wire to be supported to be easily accommodated. So that when using an insulated wire the insulation cannot be damaged by the contact edges in the notch, the contact edges can advantageously be rounded outwards.
  • a bore can be provided in a development of the invention 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 set screw.
  • 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.
  • the wire support 1 according to FIG. 1 in a side view is shown in FIG. 2 seen from the front.
  • the notch 4a of the insulating tube 4 can also be seen here.
  • the bore 4c 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 FIGS. 3 and 1.
  • wire supports 1 are shown, 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.
  • the connecting wire 7 can be guided over and supported on the wire support 1 without the length of the connecting wire 7 also being changed when the tensioned wire 17 changes in length.
  • the wire support 1 can be mounted on the mast 6 in parallel at a certain distance above the wire 17 and the insulator 8. For example, they can be attached to a round mast using pipe clips.
  • the connecting wire 7 is guided vertically upwards from the insulator 8 to the wire support 1 and from there obliquely 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.
