Definitions

  • the invention relates to insulators for electric wires or wires Tapes or ropes for fitting and / or manufacturing fences, in particular Pasture fences, consisting of an electrically insulating holding part, which a Screw or bracket for screwing in or screwing on or fastening the Has insulator on a post, in particular wooden post, the holding part is designed to hold the wire or ribbon or rope, according to the Preambles of claims 1 and 8 and the use of an adapter For this.
  • DE-3730400-A1 is a housing with slots for in and Unscrewing pasture fence insulators has become known.
  • the hook-shaped Electric fence insulator has a threaded bolt, which one Has screw thread and at the other end bent in a U-shape Insulator head carries; the insulator head is firmly connected to the threaded bolt.
  • the housing is used to screw the insulator into a post on the Insulator head pushed on and turned; then the housing is removed.
  • a pasture fence insulator has become known from EP-0307350-A2 which is a threaded hook for wood or steel in an insulating plastic holder inserted and screwed in by turning through the isolator can be.
  • the hook screw must be used to replace the insulator head only then be unscrewed or unscrewed from the mast the insulator head can be removed.
  • DE-OS 2242147 includes an insulator for electric pasture fences, at which a steel pin is hammered into an insulator head, the Insulator head can no longer be replaced. If the isolator head is on the Pressed pin, it is firmly connected to the pin.
  • the invention has for its object an insulator for electrical Live wires or bands or ropes for the production of fences to improve the genus mentioned in such a way that when exchanged only the actual insulator part needs to be replaced and the Screw can remain in place while still in order; the attachment of the insulator to the post should also be easier to accomplish be known as pasture fence isolators.
  • the holding part is a T-shaped in plan view Has recess from two perpendicular slots and the screw has one with a shaft and a widened head at least two mutually parallel side surfaces or key surfaces, especially wood screw, for the suitable, preferably clamping and non-rotating, releasable insertion of the shaft with the head perpendicular to the longitudinal axis the screw into the recess, which is a bed for the head and forms the end part of the shaft of the screw, the recess of the slots is T-shaped in plan view in the direction of insertion of the screw, and the one slot of the recess at most the clear width of the diameter of the Has screw shaft and outwards from two sides of the holding part is open and the other slot is at most the clear width of the height of the screw head has and open to the outside only from one side of the holding part is.
  • the holding part is a plastic injection-molded part, which consists of a head for holding the wire and a molded on it Base part is in which the T-shaped recess is made.
  • the isolator according to the invention has the advantage that the isolator head Isolator is designed interchangeable from the outset, so that the hook part is not needs to be unscrewed more. Defective insulators do not have to more completely replaced, but the screw can be on the post remain as long as it is still in order. Only the old isolator or Insulator head removed and a new one put on the screw. Of Another simple and quick assembly of the invention Isolators possible because the screw is using a wrench, or a riddle with a nut and TORX or a cordless battery screwdriver Nut or also easily screwed into a wooden post, for example and then the insulator can be put on. Likewise, the Screw are welded to an iron post without the Isolator is destroyed because it is only then plugged on.
  • the screws used can be inexpensive hexagon standard screws be, the T-shaped recess as a snap good fit, which can also be jammed, of the insulator on the screw accomplished. Since the length of the slot that is used to hold the head, corresponds to the width across flats of the screw, the insulator sits after the Put on the screw against rotation on the same, so that when turning of the insulator, for example by hand, now take the screw with it and rotated further into the post and especially the insulator on it Way can be aligned.
  • the isolator is much cheaper to manufacture because only the Insulator as such needs to be replaced if it is defective. As well the isolator according to the invention is more environmentally friendly since the old isolator bracket no longer remain in the pastures. The insulators to be replaced can simply put it in your pocket and put it in the trash at home.
  • the base part of the insulator can be designed as a cylinder or a cuboid, from the lower surface of which the Slots for receiving the screw are guided, the slot for Receiving the screw shaft to the outside both to the top surface and to the cylinder surface of the cylinder or one of the side surfaces of the cuboid and the slot for receiving the screw head to the outside only for Cover surface is open.

  • the holding part or the Entire insulator consist of an elastic material, in which Hold part as a recess for the screw in the direction of insertion cylindrical blind hole is introduced, which is located at the inner end inside the holding part for receiving the screw head widened, and jamming but detachable plugging of the insulator onto the screw head and the screw shaft of the screw, so that in the top view of a cut through a plane in which the longitudinal axis of the blind hole lies is designed T-shaped together with the end widening.
  • the widened end of the blind hole can be at least two have mutually parallel surfaces to prevent rotation of the screw head.
  • isolators can also be used that are made of Rubber or rubber mixtures are made, which is advantageous here Screw a round, and if necessary lenticular, slotted head with at least two mutually parallel side surfaces, so that the Insulator can be slid more easily over the screw head of the screw, until the screw head in the end widening of the blind hole is secured against rotation locks.
  • an insulator for electrical Live wires or tapes or ropes for assembly and / or manufacture of fences, especially pasture fences consisting of an electric insulating holding part, which has a holder for attaching the insulator has a post, the holding part for holding the wire or tape or rope is formed, wherein the holding part is a T-shaped in plan view Has recess from two perpendicular slots and the one slot is open to the outside from two sides of the holding part, the other Slot is open to the outside only from one side of the holding part, the Bracket is an adapter, which is T-shaped in plan view at one end Extension from a web and a transverse surface arranged thereon has, by means of the same the adapter in the T-shaped recess of the two perpendicular slots of the holding part, which a receiving bed form for the T-shaped extension, can be inserted appropriately, the adapter is cylindrical or cuboid and directly opposite the extension has a rounded or cambered groove at the end, and
  • an insulator 1 is made in a manner known to this extent formed an approximately cylindrical holding part, which integrally from one to Part consists of a frustoconical head part 2 and a cylindrical base part 3.
