Abstract
A polyvinyl chloride sheath braided-shield control flexible cable comprises, from inside to outside, a conductor, an insulating layer, a filling layer and an outer protective sleeve. A conductor shielding layer is added between the conductor and the insulating layer; and an insulating shielding layer is additionally arranged between the insulating layer and the filling layer; and a non-woven fabrics layer, an inner sheath and a steel wire armor layer are sequentially added between the filling layer and an outer sheath. The added three shielding layers can substantially improve the shielding effect and increase the service life of the flexible cable, so that the flexible cable is suitable for any environment with strong interference signals.
Description
Technical field
The utility model relates to the equipment instrument power supply, cable is used in the signal controlling transmission, relates in particular to a kind of control flexible cable.
Background technology
Present control cables on the market generally comprises conductor, insulating barrier, packed layer and oversheath, simple in structure, shield effectiveness is not good, for improving shield effectiveness, is usually setting up a screen, 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 cables 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 utility model is for the deficiencies in the prior art, provides that a kind of shield effectiveness is good, the pvc sheath jacket braided-shield control soft cable of long service life.
Key problem in technology of the present utility model 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 jacket braided-shield control soft cable, comprise successively from inside to outside conductor, 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 successively nonwoven layer between packed layer and oversheath, inner sheath, the wire armoring layer.
As preferably, described insulating barrier is crosslinked polyethylene.
As further improvement of the utility model, 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 conductor temp .-elevating, 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 again the effect of protecting cable, effectively prevented fracture.
The beneficial effects of the utility model: the utility model 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 utility model.
