Abstract
The invention provides a signal transmission cable resistant to bending. The signal transmission cable comprises a cable sheath and two conductive units, wherein the conductive units are extruded in the cable sheath and stranded into a bundle. A filling layer is arranged between the conductive units and the cable sheath. Each conductive unit comprises a conductive cable core and a split-phase insulating layer wrapping the conductive cable core, wherein the split-phase insulating layer is formed by extruding butyronitrile elastic materials, the conductive cable core comprises an aramid-fiber-reinforced core located at the center and a tinned copper conductor layer stranded outside the aramid-fiber-reinforced core, the circular-bundle-shaped aramid-fiber-reinforced core is formed by an aramid fiber bundle, and the tinned copper conductor layer is formed by stranding tinned thin copper wires. The cable sheath comprises a shielding layer and a protection cover wrapping the shielding layer. The signal transmission cable has the advantages that the signal transmission cable is resistant to bending, the torsional fatigue prevention performance is excellent, use is safe, signal transmission is stable, and the service life is long.
Description
Technical field
The invention belongs to signal-transmitting cable field, especially relate to a kind of resistant to bending signal-transmitting cable.
Background technology
Current, develop on an unprecedented scale and the improving constantly of scientific and technological level along with socioeconomic, the trend of cable industry development is the individual demand that the cable manufactured more and more should meet client, signal-transmitting cable is widely used in the every field of science and technology, and many flexible cables being used as mobile device connection control or Signal transmissions that is applied in industrial environment have quite harsh requirement to the resist bending performance of cable and the stability of Signal transmissions, at present, in all multi-vendor processes manufacturing this kind of cable, usually just have employed conventional production process by six classes or surpass six class conductors and carry out meticulous stranded, and then extrude the soft insulation of PVC and sheath, or in the core of cable, be mixed with the materials such as the aramid fiber that increases toughness and tension degree, but, the respective cable of such traditional processing technology manufacture cannot meet the property indices requirement of economic society industrial technology to required cable, anti-twist poor fatigue properties is frequently there is in actual use with the signal-transmitting cable of traditional handicraft manufacture, sheath cracking and cable core very easily therefrom connect the problem that root twists off, have a strong impact on the normal use of connection device, unnecessary trouble is caused to user, Given this, urgently develop a kind of resist bending, anti-twist excelling in fatigue property and the signal-transmitting cable of stable signal transmission.
Innovation and creation content
The problem to be solved in the present invention is to provide a kind of resist bending, anti-twist excelling in fatigue property, use safety, stable signal transmission and the signal-transmitting cable of long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of resistant to bending signal-transmitting cable, comprise cable sheath and be extruded in the conductive unit of two stranded bunchys in described cable sheath, packed layer is provided with between described conductive unit and described cable sheath, described conductive unit comprises conductor wire core and is coated on the phase-splitting insulation layer extruded by butyronitrile elastomeric material outside described conductor wire core, described conductor wire core comprises the aramid fiber strengthening core being positioned at center and the tinned copper conductor layer be stranded in outside described aramid fiber strengthening core, the described aramid fiber strengthening core of circle bundle shape is made up of aramid fiber bundle system, described tinned copper conductor layer is made up of the stranded winding of zinc-plated thin copper wire, described cable sheath comprises screen and is coated on the sheath outside described screen.
Further, the diameter of described aramid fiber strengthening core is 1/3 of the thickness of described tinned copper conductor layer.
Further, in described screen, parallel dredging is wound with zinc-plated thin copper wire.
Further, described sheath is the protective layer be made up of butyronitrile elastomeric material.
The advantage that the present invention has and good effect are: adopt technique scheme, conductor wire core adopts the double-decker of the stranded aramid fiber strengthening core of tinned copper conductor layer, compared with the structure be mixed in traditional material aramid fiber etc. being increased toughness and tensile strength in copper conductor cable core, prove through test, the conductor electrical property of conductor wire core of the present invention is unaffected, and the diameter having benefited from aramid fiber strengthening core is only 1/3 of the thickness of tinned copper conductor layer, can not additionally increase on the basis of the external diameter of cable core, toughness and the anti-twist fatigue behaviour of conductor wire core are greatly strengthened, the phenomenon of rupture of conductor wire core can not be there is, the insulation of phase-splitting insulation layer and sheath all adopt butyronitrile elastomeric material to make, and make the present invention all have splendid pliability by the conductive unit of inside to outermost sheath, and sheath can not owing to frequently moving or bendingly to ftracture, parallelly in screen to dredge around zinc-plated thin copper wire, better can shield the interference of outer signals, ensure Signal transmissions more stable.
