Abstract
The invention discloses a shield and control soft cable for polyvinyl chloride sheath knitting. The cable sequentially comprises a conductor, an insulation layer, a stuffing layer and an outer sheath from inside to outside, wherein a conductor shielding layer is additionally arranged between the conductor and the insulation layer, an insulation shielding layer is additionally arranged between the insulation layer and the stuffing layer, and a non-woven fabric layer, an inner sheath and a steel wire armored layer are sequentially and additionally arranged between the stuffing layer and the outer sheath. By additionally arranging three shielding layers, the shielding effect is greatly improved, the service life is prolonged, and the cable is suitable for application in any environment with a strong interference signal.
Description
Technical field
The present invention relates to the transmission of equipment instrument power supply, signal controlling and use cable, relate in particular to a kind of control flexible cable.
Background technology
Control cable on the market generally comprises conductor, insulating barrier, packed layer and oversheath at present, simple in structure, shield effectiveness is not good, for improving shield effectiveness, is setting up a screen usually, the external interference signal of shielding but also available its ground connection had not only been played, when short circuit, electric current is imported the earth, but existing control cable generally only comprises one deck screen, at circumstance complication, the place that external interference signal is strong is difficult to well open the effect of shielding, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide that a kind of shield effectiveness is good, the pvc sheath braid shielded of long service life control flexible cable.
Key problem in technology of the present invention is to set up three layers of screen, wherein ground floor is located between conductor and insulating barrier, the second layer is located between insulating barrier and packed layer, be located between packed layer and oversheath for the 3rd layer, concrete technical scheme is: a kind of pvc sheath braid shielded control flexible cable, comprise conductor from inside to outside successively, insulating barrier, packed layer and oversheath, it is characterized in that having additional conductor shield between conductor and insulating barrier, have additional insulation screen between insulating barrier and packed layer, have additional nonwoven layer between packed layer and oversheath successively, inner sheath, the wire armoring layer.
As preferably, described insulating barrier is crosslinked polyethylene.
As a further improvement on the present invention, described conductor is made of some strands of hinged copper wires, is filled with glass fibre in the gap of copper wire.When improving shield effectiveness again by this kind setting, effectively prevent the conductor heating, and increase its ductility and torsional strength, improve useful life.
As preferably, the wire armoring layer is the netted or thin steel band of the staggered establishment of steel wire.Namely improve shield effectiveness by this setting and played the effect of protecting cable again, effectively prevented fracture.
Beneficial effect of the present invention: the present invention has improved shield effectiveness greatly by adding 3 screens, has increased useful life, is suitable for the strong environment of any interference signal.
Description of drawings
Fig. 1 is structural representation of the present invention.
