Description
Technical field
The utility model is related to electric wire field, in particular to a kind of high shielding anti-interference flexible cables.
Background technology
Currently, since China's economy grows continuously and fast, cause supply of electric power very nervous, causes power infrastructures and throw
Providing upsurge in construction, especially high voltage power cable, extensively hair uses in urban distribution network.During cable use, to cable
It is required that very high, it is necessary first to which cable has good heat resistance, intensity, tensile strength, it is also necessary to cable have good insulation performance,
Shielding properties and anti-interference ability.
Not only other electronic equipments of severe jamming work normally the electromagnetic wave of radiation and the leakage of cable, lead to functions of the equipments
Disorderly, error of transmission.Therefore the electromagnetic interference (EMI) for reducing cable has been the problem of must take into consideration.
But the effectiveness of current cable is poor, it is difficult to meet the needs of market.
Utility model content
The technical problem to be solved by the present invention is to provide one kind having good electromagnetic shielding effect, anti-interference
Strong high shielding anti-interference flexible cable.
A kind of high shielding anti-interference flexible cable described in the utility model, including PVC fill out core, PVC fillings
Center hole slot there are one setting, four insulated wire cores slots and a shielding core slot are filled out on core；Aluminium bar is laid in the hole slot of center,
Four insulated wire cores are placed in four insulated wire cores slots respectively, shields in core slot and lays shielding core；Core is filled out in PVC
It is externally provided with aluminium strip, wrapped semiconductive nylon tape, extrudes oversheath outside semiconductive nylon tape, gold is cased with outside sheath outside aluminium strip
Belong to bellows.
Be further improved, the insulated wire cores by aluminium conductor, the insulating layer being extruded in outside aluminium conductor, around insulating layer
The polyester fiber cloth of outer barium titanate film and the surface plating charcoal for being wrapped in barium titanate film surface is constituted.
It is further improved, the shielding core is by aluminium alloy conductor and the metallic shield being extruded in outside aluminium alloy conductor
Layer is constituted.
It is further improved, the metal screen layer is formed by tinned copper wire and fibrage, wherein fibrage number of spindles
Braiding number of spindles for 18 ingots, tinned copper wire is 18 ingots, and percentage of braiding coverage is not less than 85%.
It is further improved, which further includes fluorescence radiation colour band, and the fluorescence radiation colour band is along the metal bellows
Axis direction setting.
Compared with prior art, the beneficial effects of the utility model are：
The utility model increases an aluminium bar at original flexible cable center, cable will not be caused to draw in use
Power is excessive and is broken, and prolongs the service life, can also play shielding anti-jamming effectiveness；Aluminium strip along with outer layer and semiconductive Buddhist nun
Tengential belt plays three layers of shield effectiveness so that the shield effectiveness of cable greatly improves, and interference free performance also greatly enhances；Pass through
It is coated with charcoal on polyester fiber cloth surface, there is good electromagnetic shielding effect, and is combined with barium titanate film with high
Dielectric constant, when electromagnetic wave pass through barium titanate film when electromagnetic wave speed be reduced, have shorter wavelength so that electric field it is strong
Degree has considerable decline；Metal screen layer is formed by tinned copper wire and fibrage, and wherein fibrage number of spindles is 18 ingots, plating
The braiding number of spindles of tin copper wire is 18 ingots, and percentage of braiding coverage is not less than 85%, can effectively magnetic-field radiate, protect cable sheet
Body, the anti-interference ability for improving cable are equipped with metal bellows on oversheath, can inhibit passing through for electromagnetic wave well,
With outstanding shield effectiveness；Fluorescence radiation colour band is arranged in the axis direction of the metal bellows, can be in dark or light
It itself can shine under the environment of line deficiency, make people that can intuitively see cable position clearly in daily production and living, just
In effectively avoiding cable run, in order to avoid damage cable, is also prevented from and is hindered by impaired cable, more under dark surrounds maintenance, rob
Repair and safeguard etc. that related works provide a convenient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode：
As shown in Figure 1, a kind of high shielding anti-interference flexible cable described in the utility model, including PVC fill out core 1, institute
The PVC stated fill out on core set there are one center hole slot, four insulated wire cores slots and one shielding core slot；In the hole slot of center
Aluminium bar 13 is laid, places four insulated wire cores in four insulated wire cores slots respectively, shields in core slot and lays shielding core；
The insulated wire cores by aluminium conductor 2, the insulating layer being extruded in outside aluminium conductor 3, the barium titanate film 4 outside insulating layer with
And it is wrapped in the composition of polyester fiber cloth 5 of the surface plating charcoal on barium titanate film surface；The shielding core is by aluminium alloy conductor 6
And the metal screen layer 7 being extruded in outside aluminium alloy conductor is constituted, metal screen layer is formed by tinned copper wire and fibrage,
Middle fibrage number of spindles is 18 ingots, and the braiding number of spindles of tinned copper wire is 18 ingots, and percentage of braiding coverage is not less than 85%；It is filled out in PVC
Core is externally provided with aluminium strip 8, and wrapped semiconductive nylon tape 9, extrudes oversheath 10, outside sheath outside semiconductive nylon tape outside aluminium strip
It is cased with metal bellows 11.
The cable further includes fluorescence radiation colour band 12, axis direction of the fluorescence radiation colour band along the metal bellows
Setting itself can shine in the environment of dark or insufficient light, make people can be intuitive in daily production and living
See cable position clearly, convenient for effectively avoiding cable run, so as not to damage cable, be also prevented from and hindered by impaired cable, more
