Definitions
- This invention relates in general to electric cables and more specifically to shielded cables utilizing a continuous metallic surface as a shield.
- a conductor in order to eliminate external electromagnetic interference, and in high voltage applications, to provide a ground for leakage currents.
- shields consisting of a continuous metallic foil are more effective for these purposes than braided wire shields, but the use of a foil shield raises the problem of providing means to ground the foil layer.
- the present art provides a drain wire as an additional component within the cable located adjacent to the conductive surface of the shield.
- the shielding tape includes a metallic foil bonded to a non-conductive base strip and one or more drain wires fixed between the foil and the base strip.
- the drain wires are bonded to the opposite side of the foil layer by additional non-conductive strips.
- the imbedded drain wire is separated from the foil and connected to a grounding terminal.
- a principal object of this invention is to provide a shielded cable with the drain wires incorporated into the shielding so that flexing and other stresses do not damage the insulation or otherwise impair the effectiveness of the cable.
- a further object of this invention is to provide a foil laminate shielding tape which may be helically or longitudinally wound around the conductors.
- Still a further object of the invention is to provide a foil laminate shielding tape which maintains intimate contact with a drain wire.
- FIG. 1 is a cut-away view of one embodiment of a shielded cable constructed in accordance with this invention.
- FIG. 2 is a side elevation in partial cross section of the shielded cable shown in FIG. 1.
- FIG. 3 is a view of one embodiment of a shielding tape constructed in accordance with this invention.
- FIG. 4 is a view of another embodiment of a shielding tape constructed in accordance with this invention.
- FIGS. land 2 a pair of elongated wire conductors 11 are protected by inner sheaths of insulation 12.
- An insulation filler 13 surrounds the conductors and serves to insulate and to geometrically stabilize the conductors 11.
- the outer surface of the filler layer 13 is preferably uniform and approximately, but not necessarily, circular.
- a foil laminate shielding tape 14 is helically wound around the filler 13 so that the conductors 11 are surrounded by a continuous conductive shield. An overlap in the windings is recommended to guarantee shield integrity. Integral with the shielding tape 14 .are two'elongated, mutually parallel drain wires 15.
- the drain wires 15 are bonded between a non-conductive base strip 16 and a metallic foil 17 which acts as the conductive surface of the shield.
- the drain wires 15. are in continuous electrical contact with the foil 17 and provide a convenient connection from the foil shielding surface to a grounding terminal.
- the foil tape shield 14 is further enclosed by an outer layer 20 which electrically insulates and protects against physical or atmospheric damage.
- a suitable outer layer may consist of an extruded covering or a glass braid with a finish such as silicone or polyimide lacquer.
- the drain wires 15 are incorporated into the shielding tape 14 by bonding them to the surface of the metallic foil 17 opposite to the non-conductive base strip 16. Bonding is accomplished by means of holding strips 19, which cover the drain wires 15 and are bonded to the foil 16 on both sides of the drain wires 15 by a strippable adhesive layer 21.
- the bonding strips 19 may consist of the same material as the base strip 16. When this embodiment is employed, the drain wires 15 are exposed for grounding by removing a portion of the holding strips 19.
- FIG. 4 shows a cross section of the shielding tape 14 employed in FIGS. 1 and 2.
- the non-conductive strip 16 may be polyester, vinyl; asbestos or any other insulation of similar conductive and physical characteristics. The use of such a strip gives the shielding tape much higher tensile strength and greater flexing qualities than a shield consisting solely of a metallic foil. Good results are achieved with a 0.001 inch polyester film.
- the width of the strip will vary with the diameter of the 'material being shielded and the type of winding employed, but strips are typically three-fourths inch to 1 inch in width.
- the metallic foil layer 17 may consist of an aluminum foil of approximately 0.001 inch thickness or similar foils of other metals. The foillayer 17 is bonded to the base strip 16 by an adhesive layer 18.
- the adhesive may be any conventional bonding agent suchas a polyester resin.
- the drain wires 15 may consist of any suitable conductor such as tinned or bare copper. They may be flat, round, or any other shape which has good flexing and bonding characteristics. In the preferred embodiment of the invention, thedrain wires are flat, since this configuration best resists displacement and insulation damage.
- a shield tape constructed in accordance with the invention may employ one or any number of drain wires 15.
- FIG. 4 illustrates another embodiment of the invention in which a number of copper strands will have a diameter of 0.006 to 0.012 inches and be spaced approximately one-sixteenth inch apart.
- the drain wires are fixed between the foil 17 and the base 16 in a mutually parallel configuration.
- the drain wires 15' are located so that they divide the shielding tape approximately into thirds. If a single drain wire is used, it is preferably located one third of the width of the tape from the edge. However, the preferred embodiment employs two drain wires since a single drain wire produces a crown in the shielding tape which makes it difficult to roll the tape into a reel for storage.
- FIG. 6 shows a view in cross section of a shielded cable in which the tape shield 14 is wound longitudinally rather than helically.
- the width of the shielding tape 14 must be sufficient to completely encircle the conductors.
- the edges of the tape should overlap slightly to insure a continuous shield.
- the tape shield 14 of this invention may also be used to shield single conductors, coaxial cables, groups of conductors in a multi-conductor cable, or the overall cable and all of its component conductors.
- a shielded electric cable comprising:
- a central elongated conductor 7
- a shield consisting of a laminated tape helically wound around said insulation to form a continuous conductive surface, said tape comprising a flexible non conductive base strip, a metallic foil adhesively bonded to said base strip, and at least one longitudinal drain wire in continuous electrical contact with said foil interposed between said foil and said base strip;
- a shieldingtape for use in an electric cable comprising a flexible, non-conductive base strip, a metallic foil adhesively bonded to said base strip, and at least one longitudinal drain wire disposed in continuous electrical contact with said foil between said foil and said base strip.
