Abstract
The invention discloses an anti-interference sensor signal cable. The cable comprises an outer protective sleeve, an outer shielding sleeve and composite conductors. The outer protective sleeve is disposed outside the outer shielding sleeve. Three or six composite conductors are provided, and are disposed inside the outer shielding sleeve in a symmetrical manner. Each composite conductor comprises a conductive core body, a winding protection layer, a first insulating sleeve, an inner shielding sleeve and a second insulating sleeve, wherein the second insulating sleeve is arranged outside the conductive core body, the inner shielding sleeve is arranged outside the second insulating sleeve, the first insulating sleeve is arranged outside the inner shielding sleeve, and the winding protection layer is arranged outside the first insulating sleeve. Through the above way, dual-layer shielding effects are achieved, and the inner first insulating sleeves and the inner second insulating sleeves enable the conductive core bodies to be reinforced in structure. Therefore, the anti-interference sensor signal cable exhibits good bending resistance and is long in service life.
Description
Technical field
The present invention relates to signal cable design field, particularly relate to a kind of Anti-interference sensor signal cable.
Background technology
Cable is normally made up of several or several groups of wires, and often organize mutually insulated between wire, whole outside is surrounded by the cover layer of high-insulation, has interior energising, the feature of external insulation.According to purposes, cable is divided into power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, mining cable, aluminium alloy cable etc.Wherein, signal cable is a kind of Signal transmissions instrument, and the signal of general signal cable transmission is all very faint, is therefore very easy to by external interference.
In order to avoid signal is interfered, signal cable is generally provided with one deck screen in outside.Screen is made up of conductive metal material, screen needs grounding, external interference signal just can be imported ground by this layer and lose interference, in long-term use procedure, single screen is often unable to undergo repeatedly to bend, easy fracture and lose the effect of shielding, causes Signal transmissions disturbed.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Anti-interference sensor signal cable, and antijamming capability is strong, and resistance to bending, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of Anti-interference sensor signal cable, comprise: outer protection cover, exterior shield cover and composite electric conductor, described outer protection is set on the outside of exterior shield cover, described composite electric conductor is three or six, described composite electric conductor is symmetricly set in exterior shield cover respectively, described composite electric conductor comprises conductive core, winding protective layer, first insulating case, internal shield cover and the second insulating case, described second insulating case is arranged on the outside of conductive core, described internal shield is set on the outside of the second insulating case, described first insulating case is arranged on the outside of internal shield cover, described winding protective layer is arranged on the outside of the first insulating case.
In a preferred embodiment of the present invention, described exterior shield cover is conductive fabric cover.
In a preferred embodiment of the present invention, described internal shield cover is aluminium foil cylinder.
