Definitions

  • This invention provides a detachable tubular shielded I jacket assembly for use about conductors, cables and the like and serving as a highly effective barrier against the passage of electrical flux field.
  • the assembly comprises an impervious flexible main body of insulating material provided with a pair of seam-foaming tapes along the lateral edge portions thereof and a unique flexible electrically conductive liner co-extensive with the interior of the main body attached thereto only along one lateral edge.
  • Theedge to which the liner is attached preferably includes a guard flap portion sufiiciently wide to underlie the seam-forming members and to overlap with the other edge of the main body.
  • Conductive material embraces the free edge of this guard flap to the end that the guard flap may be positioned against either side of the other free edge of the liner to form a continuous metal contact therewith thereby assuring a complete tubular shielding barrier surrounding the members enclosed by the jacket assembly.
  • Various proposals have been made in the past to provide a protective shielding enclosure for cables, conductors and other components and capable of preventing the passage of any substantial electrical flux in either direction through the barrier assembly. Although certain of these are quite effective from a functional standpoint they are subject to certain disadvantages sought to be overcome .by the present invention.
  • prior 'shields of conductive material lack the requisite fiexivbility and deformability found desirable in many applications of shielding assemblies.
  • bundles of wiring having numerous branchouts and used to connect sub-assemblies of electrical components vary widely in size and contour owing to cross-over of wires within a particular branch and other causes.
  • attempts to assemble shielding jackets having barrier or shielding layers formed of foil rupture if undue stress is placed on them. Such ruptures are unlikely to be detected and result in serious loss of shielding efficiency for reasons not readily ascertainable or observable from the exterior of .,the assembled jackets.
  • the liner is sufficiently w-ide that one lateral edge overlaps and bearsdirectly against the other lateral edge in the fuly assembed position of the jacket thereby assuring a continuous tubular enclosure of electrically conductive material.
  • the main body of the jacket is preferably formed of supple stretchable thermoplastic material having interlockable plastic seam-forming means secured to its edges in such manner as to hold the conductive and shielding liner assembled in the manner just described.
  • the jacket body is preferably heat-reactive and capable of pronounced shrinkage upon the application of heat for a short interval thereby facilitating the assembly of the jacket loosely about the conductors, cabling or other object to be shielded and thereafter shrunk into a snug fit with the enclosed object.
  • the flexible, stretchable and contractable shielding contracts in response to the shrinkage of the jacket or, in certain instances, stretches as the shielding assembly is pulled taut about some bulge or obstacle being enclosed by the jacket as shrinkage occurs. Prior shielding layers would be subject to rupture or damage by shrinkage of the body layer about :an obstruction or protuberance.
  • Another object of the invention is to provide a detachable unitary seamed jacket assembly for enclosing cables, conductors and the like with a continuous tubular electrical shield capable of stretching, contracting and conforming to a wide variety of shapes and sizes.
  • Another object of the invention is the provision of a detachable unitary jacket assembly for conductors or other object to be enclosed within an electrical shield wherein both the shield and the supporting layer are stretchable and contractable to accommodate irregularities and variations in size and shape without risk of rupture or failure to the electrical shield.
  • Another object of the invention is the provision of a unitary tubular shielding jacket assembly effective as a barrier to electrical flux fields and including an impervious body of heat-reactive insulative material and an attached shiegiing layer of stretchable contractable conductive mes
  • a unitary jacket assembly having a heat-reactive main body and a layer of electrical shielding material attached to said main body only along a narrow strip and said main body being otherwise free to stretch and contract independently of said shielding material.
  • FIGURE 1 is a fragmentary perspective view of a preferred embodiment of the invention with the seam thereof closed;
  • FIGURE 2 is a fragmentary cross-sectional view on enlarged scale taken along line 22 on FIGURE 1;
  • FIGURE 3 is a fragmentary view of a small area of a single layer of the liner.
  • FIGURE 1 there is shown a typical shielding jacket assembly designated generally 10 embodying the principles of this invention.
  • This assembly includes a main body 11 of thin, supple, im-
  • pervious stretchable insulating material as, for example, any of a variety of thermoplastic materials such as polyvinyl chloride, polyethylene, tetrafluoroethylene polymer and many others.
  • This main body is made in a continuous strip having a width such that its opposite lateral edges will overlap one another by a substantial distance when the jacket seam is closed.
  • the main body strip is treated by any one of several wellknown techniques to render the same heat-reactive or shrinkable when subjected briefly to relatively low temperature heating, as by an ultra-red lamp, a hot air blower or the like.
  • the seam comprises a pair of tapes 14, 15 each having a mounting web 16, 17. Their adjacent lateral edges are provided with any suitable interlocking tongue and groove means cooperating when mated to provide a strong continuous seam extending lengthwise of the jacket.
  • tape 14 is provided with a T-shaped head portion 18 insertable between the legs of the U-shaped portion 19 along the free edge of tape 15. It will be understood that tapes 14 and 15 are preferably formed of a suitable thermoplastic readily extruded in the cross-sectional shape desired.
  • Mounting webs 16 and 17 of the tapes may be suitably bonded of heat-fused to the main body strip 11, web 16 of tape 14 being secured to the jacket body sufiiciently inwardly of one edge to provide a wide guard flap 22.
  • this guard flap entirely bridges the seam-forming tapes and overlaps substantially with the other edge "of the main body. This serves not only to prevent the conductors or other material being enclosed from interfering with the closure of the seam but, in particular, assures that the electrical barrier material will completely encircle the cable without the possibility of gaps through which electrical fields might pass.
  • the electrically conductive shielding barrier 25 featured by this invention comprises at least one, and preferably a plurality of closely superimposed layers of knit mesh material in intimate contact with one another and each typically fabricated as shown in FIGURE 3.
  • each layer of this material includes a maze of fine, flexible, resilient wires 26 interlocked by a multiplicity of loops with the similarly looped wire to either side thereof.
  • the individual wires as well as the loops in each are very small and highly effective in barring the passage of electrical flux fields. This is particularly true when two or more layers of the knit mesh are superimposed. Only two layers are shown in FIG- URE 1 but it will be understood that additional layers may be employed depending upon the importance of complete shielding effectiveness.
  • the material Owing to the fineness of the wire, its resiliency and flexibility, as well as the knit character of the mesh, it will be understood that the material exhibits unusual flexibility, stretchability, contractability and ability to conform to the shape and size of the conductors being enclosed. Additionally, the mesh material has unusual strength and rupture resisting characteristics.
  • the mesh liner 25 is secured to main body 11 only along one edge of the main body and preferably along the, free edge 28 of guard flap 22.
  • the remainder of liner 25, including its other lateral edge 29 of the liner, according to a preferred mode of construction, is free of attachment to the main body. Accordingly, the entire liner is free to contract, expand, and stretch relative to its individual layers and relative to the main body 11.
  • guard flap 22 may be inserted along the interior surface of the conductive liner or between the free edge 29 thereof and the adjacent inner surface of the jacket body. As illustrated in FIGURE 1, the guard flap is located in the former position.
  • FIGURE 2 illustrates a strip of U-shaped metal foil 32 embracing the edge of the guard flap and the adjacent edge of the liner and secured in position along with a strip of metal braid 33 or the like conductive wire by stitching 34. This detail is shown in FIGURE 2.
  • jacket assembly 10 lies flat with the seam-forming tapes 14 and 15 disengaged and with the liner mesh 25 lying flat against main body 11.
  • the assembly of the jacket about a cable is accomplished by embracing the opposite edges of the jacket and liner about a bundle of conductors, care being taken to insert the free edge of guard flap 22 either beneath the free edge 29 of the liner or between this edge and the adjacent body of the jacket.
  • the T-head portion 18 of tape 14 is advanced between the tanged end of the legs of the U-shaped portion 19 of tape 15 until the parts interlock.
  • a suitable tool may be employed to facilitate the seam closing operation.
  • the flexibility and resiliency of the jacket assembly enables the jacket to accommodate itself easily and quickly to the shape and size of the conductors being enclosed without risk of disrupting or interfering with the continuous and excellent electrical contact between the overlapped edges of the shielding liner 25.
  • a snug fit is assured if the main body is heat-reactive and subjected to heat from a hot air blower or a heat lamp until the jacket has shrunk into a snug fit whereupon further heating is discontinued.
  • a tubular jacket assembly for detachable assembly about conductors, cabling and the like to provide an effective barrier to electrical fields
