Abstract
The invention discloses a waterproof soft cable which comprises a cable core. The cable core is formed by twisting three insulating wire cores. A stuffing layer formed by stuffing is arranged in a gap in the cable core. The outmost layer of the cable is coated with a polyurethane elastomer outer protective layer in an extruding mode. Each insulating wire core is composed of a copper conductor and insulating layers sequentially wound on outside the conductor. Compared with an existing waterproof cable, fundamental difference is that an outer protective sleeve is made of a different material, and therefore the waterproof soft cable has the functions of an ordinary waterproof cable, can work normally under the extremely cold condition of low temperature of -40 DEG C and is pressure resistant, anti-abrasion, anti-corrosion and capable of maintaining soft performance.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of low temperature resistant, wear-resistant, corrosion-resistant, waterproof flexible cable.
Background technology
Since entering for 21st century, electric wire is along with power industry, data communication, and the development that the industry sizes such as car industry and communications enlarge to the demand of electric wire with require also to improve rapidly, makes following cable industry that huge development potentiality be arranged.
Existing cable mainly is comprised of inner wire, insulating barrier, outer conductor and sheath at present; Because of its instructions for use; more be exposed to outdoor; and in outdoor construction; often can encounter as uncertain environment factor, sheath skins such as low temperature cold current, acid and alkali corrosion, greasy dirt, extruding and suffer damage or junction, cable two ends when poorly sealed; moisture and rainwater are very easily along the braided outer conductor leaking; outer conductor is corroded; thereby the shielding properties of outer conductor is descended; cause that attenuation constant becomes large, shielding attenuation reduces, degradation under insulation resistance; when the cable outer conductor seriously corroded, cable will be scrapped because losing transfer function.Even form the phenomenon that the globule infiltrates connector, rack, so that damage the serious consequence of a whole set of cabinet equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low temperature resistant, wear-resistant, corrosion-resistant, soft water-proof cable, meets the need of market.
A kind of waterproof flexible cable of the present invention comprises cable core, and cable core is by stranded the forming of some eradication edge cores; Cable core internal pore place is provided with packed layer, and the cable outermost layer extrudes outer jacket; Described insulated wire cores is by copper conductor and wrappedly successively consist of at the conductor external insulation layer.
Further improve, described insulated wire cores is three.
Further improve, described conductor is soft round copper stranded conductor.
Further improve, described insulating barrier is ethylene propylene rubber insulated.
Further improve, described packed layer is that polythene material is filled.
Further improve, described outer jacket is the polyurethane elastomer oversheath again.
Beneficial effect of the present invention:
1, insulating barrier is ethylene-propylene rubber (EPR) insulation, has excellent electrical property, and its specific insulation is high, have outstanding water resistant tree and corona-resistance property, stable anti-electric pulse intensity, very wide serviceability temperature, low thermal coefficient of expansion can prevent insulating barrier separation, joint or end retraction;
2, oversheath adopts polyurethane elastomer material, because of its polar macromolecule material that is formed by many soft segments and rigid chain segment, along with the raising of rigid chain segment ratio and the increase of polar group density, the former intensity of elastomer and the corresponding raising of hardness meeting, particularly water is being arranged, under the condition of work that the wet goods wetted media exists, its resistance to wear is several times to tens times of General Purpose Rubber material often, and its processing mode is various, can be the same with common plastics, use injection, extrude, calendering, the technological formings such as blowing, therefore polyurethane elastomer material is excellent, has oil resistant, anti-ozone, ageing-resistant, radiation hardness, low temperature resistant, the performances such as bonding force is strong, also have simultaneously biocompatibility and the good characteristics of blood compatibility.
3, be that from the fundamental difference of existing water-proof cable the jacket material of using is fully different, therefore the present invention is except answering performance of having common water-proof cable, still possess under extremely cold low temperature (40 ℃) condition and normally use, and withstand voltage, wear-resisting, corrosion-resistant, and keep flexible nature.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of waterproof flexible cable of the present invention comprises cable core, it is characterized in that, cable core is to thoroughly do away with stranded the forming of edge core by three; Cable core internal pore place is provided with fills the packed layer 3 of making, and the cable outermost layer extrudes polyurethane elastomer outer jacket 4; Described insulated wire cores is by copper conductor 1 and wrappedly successively consist of at conductor 1 external insulation layer 2.
The invention provides a kind of thinking and implementation method of waterproof flexible 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.
