Abstract
The invention discloses a signal cable for a high anti-interference sensor. The signal cable comprises a cable core, a plurality of insulated wire cores are stranded to form the cable core, each insulated wire core comprises a conductor and an insulated layer extruded outside the conductor, a filling layer is arranged at a gap in the cable core, a metal shielding layer is wrapped outside the cable core, an outer sheath is extruded on the outermost layer of the cable, and the metal shielding layer comprises a first double-layer aluminum foil shielding belt, a double-layer aluminum alloy wire woven belt and a second double-layer aluminum foil shielding belt which are combined. By the design of the signal cable, excellent shielding effects and cost performance can be ensured, a signal can be effectively and highly stably transmitted and is undistorted, and the signal cable meets strict requirements of high-precision facilities on shielding and has excellent bendability and use convenience.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of high anti-interference type inductor signal cable.
Background technology
Induction technology is the important technical basis of new technology revolution and information-intensive society.along with the highly sophisticated device instrument to photoelectric sensor, the harsh demand of the anti-electromagnetic interference performances of various inductors such as induction alarm device, this also has higher requirement to supporting anti-emi characteristics with the inductor cable simultaneously, and the supporting inductor cable of using traditionally, its structure is generally copper conductor polyethylene insulation proof copper-wire braided pvc sheath, thereby caused the anti-electromagnetic interference effect of product relatively poor, often have that " signal transmission is unstable, distorted signals, the instrument misoperation " phenomenon, obvious this individual layer brass wire shielding can not satisfy the harsh requirement of some inductor antagonism emi characteristics.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high anti-interference type inductor signal cable, can guarantee excellent shield effectiveness, effectively guarantee the highly stable transmission of signal and undistorted, satisfy high-accuracy facility to the strict demand of shielding, also had excellent bendability and ease of use and cost performance simultaneously.
A kind of high anti-interference type inductor signal cable of the present invention comprises cable core, and the gap in its cable core is provided with packed layer, the outer wrapped metal screen layer of cable core, and the cable outermost layer extrudes oversheath; Described metal screen layer is combined by double-layer aluminum-foil the first mask tape, double-layer aluminium alloy silk braid over braid and double-layer aluminum-foil secondary shielding band.
Further improve, described cable core is by stranded the forming of many eradications edge core; Its insulated wire cores is by conductor and is extruded in the outer insulating barrier of conductor and consists of.
Further improve, described conductor adopts the zinc-plated fine copper wire multiply of high conductivity that to have 16 filament diameters the be 0.20mm structure that tangles again, and its sectional area is 0.5mm
2
Further improve, described aluminium foil the first mask tape, aluminium foil secondary shielding tape thickness are 0.05mm again.
Beneficial effect of the present invention:
The present invention's design structurally can be guaranteed excellent shield effectiveness, effectively guarantees the highly stable transmission of signal and undistorted, has satisfied high-accuracy facility to the strict demand of shielding.Cable has excellent bendability and ease of use simultaneously.The a large amount of Halogen toxic gases that discharge when burning with traditional cable are compared with dense smoke, only produce the gas of a small amount of LSZH during this product burning, belong to environmentally friendly machine.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of high anti-interference type inductor signal cable of the present invention comprises cable core, and its cable core is by stranded the forming of many eradications edge core; Its insulated wire cores is to be 0.5mm by tangle the again sectional area of structure of the employing zinc-plated fine copper wire multiply of high conductivity that to have 16 filament diameters be 0.20mm
2Conductor 1 and the insulating barrier 2 that is extruded in the outer employing low density polyethylene (LDPE) insulating material of conductor 1 consist of.Gap in cable core is provided with packed layer 3, the metal screen layer that after stranding, the aluminium foil secondary shielding band 6 of the aluminum-alloy wire braid over braid 5 of overlapping wrapped aluminium foil the first mask tape 4 by double-deck 0.05mm thickness, bilayer and double-deck 0.05mm thickness combines extrudes soft low smoke halogen-free flame-retardant polyolefin oversheath 7 at the cable outermost layer.
The invention provides a kind of high anti-interference type inductor thinking and the implementation method of signal cable; concrete application approach is a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
