Definitions

  • a circular helical wave guide in which, with a view more particularly to preventing a turn of wire from [30] Forelgn Apphcatlon pr'onty Dam parting with the cylinder thus constituted, more par- Feb. 26. 1973 France 73.06734 ticularly in the case of bending of the guide, the said wire has a quadrangular cross-section, preferably with [52] US. Cl. 333/95 A; 29/600, oblique sides, That wire may also be cemented to the [51] Int. Cl.
  • wire may also have their adjacent faces cemented t0- 88/131 29/600 gether.
  • the wire may previously be pasted with a layer of polymer on its face on the external sideof the guide [56] References Cited and it may also be bi-metallic.
  • the invention has for its object a wave guide which is not subject to the drawback that same turns of wire forming the wave guide are displaced towards the inside of the wave guide when it is bent.
  • That wave guide is characterised in that the wires constituting the guide have a guadrangular crosssection, preferably with oblique sides; due to that arrangement, when the guide is bent, the sides of adjacent turns have a tendency to jam in relation to one another, this preventing the turns from coming out of the cylinder which they constitute.
  • FIG. 1 is a part transversal cutaway view of a wave guide of known type
  • FIG. 2 is a part cutaway view of a wave guide according to the invention.
  • FIG. 3 is a cross-sectional view illustrating one variation of the invention.
  • FIG. 4 is cross-sectional view illustrating another variation of the invention.
  • FIG. 5 is a cross-sectional view illustrating yet another variation of the invention.
  • a wave guide of known type consists of cylindrical wires such as 1 under an insulating sheath 2. It will be seen that, when the wave guide is bent, certain wires such as 3 may part from the cylinder on which the wires are wound.
  • the present invention avoids the disadvantage of the prior art by forming the wave guide of a wire 4 having a quadrangular cross-section and oblique sides. Because of this geometry, when the wave guide is bent, the sides of adjacent turns have a tendency to jam in relation to one another.
  • these wires may be covered with a suitable thin varnish, or be coated with, before their winding, with a layer of plastic material, such as a poly- .quently increases the coefficient of friction between" leri which makes them slightly rough and consetheir sides. 7 i-
  • a" layer of cement is applied by any method between the v face of the conductor wires, on which the said insulat ing sheath should come and the internal face of the said insulating casing.
  • FIG, 3 shows that the wires 4 are cemented to the sheath 2 by a layer 5 which may be either a layer of cement applied to atthe time of'manufacturing the guide or a layer of polymer previously pasted on the face of the wire 4 on the external side of the guide.
  • a layer 5 which may be either a layer of cement applied to atthe time of'manufacturing the guide or a layer of polymer previously pasted on the face of the wire 4 on the external side of the guide.
  • the faces of the wires are also coated with a layer of cement in order to ensure a mechanical connection between the various turns and to form, thus, a compact assembly, without the possibility for the turn to escape.
  • FIG. 4 shows wires 4 whose opposite faces are cemented together at 6.
  • the fixing cement for the insulating sheath may be based on usual polyethylene and the fixing cement between the various turns may be a grafted copolymer of acrylic acid or polyisocyanate or an epoxy resin.
  • the quadrangular metallic wire constituting the guide is pasted on its face on the outside of the guide, with a layer of copolymer, on which will be cemented or welded the insulating sheath applied to the guide or one or several insulating tapes laid with an appropriate pitch.
  • the quadrangular wire is a bi-metallic wire, whose face on the internal side of the guide is made of a metal having good conductivity and whose face on the external side is made of a metal such as aluminum or steel pasted with a layer of polymer such as polyethylene.
  • FIG. 5 shows the use of a bi-metallic wire, whose layer 7 on the internal side of the guide is made of a metal which is a good conductor, such as copper, and whose layer 8 on the external side is made of a metal such as aluminum or iron, subsequently cemented at 5 to the sheath 2.
  • the close connection between the pasted polymer layer and the insulating casing of the guide may be produced by any method, for example by a thermal action obtained either by the actual heat of the extrusion if the casing is roved, or by an outside heat source, for example by a generator of infra-red radiation.
  • a circular wave guide consisting of a helical winding in contiguous turns of a conductor wire having a quadrangular cross-section with oblique and parallel sides and being coated with an insulating sheathing material, whereby certain turns are prevented from parting with the cylinder which they constitute when the wave guide is bent.
