Abstract
The utility model discloses a sensor signal cable comprising an external protective sleeve, a shielding net sleeve, a winding isolating layer, and a plurality of enclosed conductors. The external protective sleeve is disposed outside the shielding net sleeve. The winding isolating layer is disposed inside the shielding net sleeve. The plurality of enclosed conductors are symmetrically arranged in the winding isolating layer and do not contact one another. Each enclosed conductor comprises a sub-shielding layer, an insulating sleeve, and a conductor. The insulating sleeve is arranged outside the conductor. The sub-shielding layer is arranged outside the sub-shielding layer. By means of the above manner, the utility model provides the sensor signal cable. The enclosed conductors are respectively provided with an independent shielding layer and do not interfere mutually. The total shielding net sleeve is disposed outside the enclosed conductors so as to achieve double-layer interference prevention and a good shielding effect. The sensor signal cable is not liable to interference and not liable to be damaged by repeated bending, and is stable in signal transmission.
Description
Technical field
The utility model relates to signal cable design field, particularly relates to a kind of sensor signal cable.
Background technology
Cable is normally made up of several or several groups of wires, mutually insulated between every group of wire, and 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 delivery means, and the signal of general signal cable transmission is all very faint, is therefore very easy to by external interference.
Be interfered for fear of signal, signal cable is generally provided with one deck screen in outside.Screen is made up of metallic conduction material, screen needs grounding, and external interference signal just can be imported ground and lose interference by this layer, in long-term use procedure, single screen is often unable to undergo repeatedly to bend, and easily ruptures and loses the effect of shielding.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of sensor signal cable, stable signal transmission, and shielding effective, durability is good, is difficult for disturbed.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of sensor signal cable is provided, comprise: outer protection cover, shielding net, be wound around separator and several sealing conductors, described outer protection is set on the outside of shielding net, described winding separator is arranged on the inside of shielding net, described several sealing conductors are symmetricly set on respectively and are wound around in separator and do not contact mutually, described sealing conductor comprises respectively sub-screen, insulating case and electric conductor, described insulating case is arranged on the outside of electric conductor, described sub-screen is arranged on the outside of insulating case.
In preferred embodiment of the utility model, described shielding net is braiding copper mesh cover or conductive fabric cover.
In preferred embodiment of the utility model, described screen is Copper Foil cylinder or aluminium foil cylinder.
In preferred embodiment of the utility model, described outer protection cover and insulating case are respectively the rubber sleeve of insulation.
In preferred embodiment of the utility model, described winding separator is low-density polyethylene material.
In preferred embodiment of the utility model, the quantity of described sealing conductor is three or six.
In preferred embodiment of the utility model, described electric conductor is the silver-plated conductor of multicore.
The beneficial effects of the utility model are: a kind of sensor signal cable that the utility model is pointed out, every sealing conductor is all provided with independent screen, be independent of each other, and outside also has overall shielding net, double-deck anti-tampering, shielding effective, is difficult for disturbed, repeatedly bending be also difficult for destroyed, stable signal transmission.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
