Abstract
The utility model discloses a double-shield anti-disturbance communication cable, which comprises a plurality of conductors, insulation layers are wrapped on the conductors, and the conductors are stranded to form a cable core. The double-shield anti-disturbance communication cable is characterized in that a taped covering layer, a branch shielding layer, an inner sheath layer, a main shielding layer and an outer sheath layer are sequentially wrapped outside the cable core. The branch shielding layer and the main shielding layer are formed by knitting tin plated copper lines, knitting tightness of the branch shielding layer is not smaller than 90%, and the knitting tightness of the main shielding layer is not smaller than 93%. The double-shield anti-disturbance communication cable adopts the double-shield double-sheath structure, the knitting tightness of the branch shielding layer and the main shielding layer is increased gradually, capacity of resisting disturbance of outside signals is improved, and transmission quality is not affected in special environment.
Description
Technical field:
The utility model relates to traffic basic information collection in the intelligent transport technology, treatment facility and related software technology, specifically is a kind of anti-interference communication cable of the matched double shield of boats and ships detection system that is.
Background technology:
Satisfy boats and ships signal and communication cable, antijamming capability is strong, anticorrosion, anti-salt fog, waterproof, protection against rodents, fire-retardant, LSZH, mechanical strength are high with electrical insulating property, and long service life reaches can guarantee highly reliable service in complex environment.Adopt common this cable of materials processing to be difficult to reach the high standard requirement; The cable insulation and the sheath of traditional type are selected TPO for use; Though electric strength is high, anticorrosion, fire-retardant, resistance to ag(e)ing etc. are relatively poor, though rubber insulation and sheath are soft in addition; But weatherability, resistance to ag(e)ing, flame resistance are poor, more than two big types material all can not satisfy the instructions for use of particular surroundings.
Through searching interrelated data and to the consulting of how tame manufacture of materials producer; Material property is compared; Insulate with a kind of environment-protecting thermoplastic low-smoke halide-free fireproof composite polyolefine material through screening; Sheath is selected environment-friendly type polyethers flame-retardant thermoplastic elastomer for use, therefore the double shield boats and ships is developed with anti-interference communication cable.
The utility model content:
The purpose of the utility model provides the anti-interference communication cable of a kind of double shield, reasonable in design, and the interference of the electromagnetic field that reduces to come from the outside has guaranteed that communication quality is unaffected in rugged environment.
The technical scheme of the utility model is following:
The anti-interference communication cable of double shield; Include the mutual stranded formation cable core of conductor of several wrap insulate layers; It is characterized in that: cable core is enclosed with lapping layer, sub-shield, inner restrictive coating, total screen, external sheath layer outward successively; Described sub-shield is that the tinned wird braiding constitutes with total screen, and the sub-shield count is not less than 90%, and total screen count is not less than 93%.
The anti-interference communication cable of described double shield is characterized in that: described conductor adopts multiply tin-coated copper wire harness to close and forms.
The anti-interference communication cable of described double shield is characterized in that: described insulating barrier adopts the environment-protecting thermoplastic low smoke halogen-free flame-retardant polyolefin.
The anti-interference communication cable of described double shield is characterized in that: it is environment-friendly type polyethers flame-retardant thermoplastic elastomer that described inner restrictive coating, external sheath layer adopt material.
The utility model has the advantages that:
1, conductor is selected solderability tinned wird good, that resistance to corrosion is strong and performance is very stable in atmospheric environment for use, guarantees the communication quality of particular surroundings, adopts bundle zygonema cored structure to satisfy the pliability requirement.
2, insulating barrier adopts and has the dielectric strength height; Anticorrosion, superior, the low cigarette of anti-flammability; Smoke intensity is very few when environment-protecting thermoplastic low smoke halogen-free flame-retardant polyolefin, this material combustion, and non-corrosiveness gas is overflowed; Can not bring injury to environment, checkout equipment, vehicle electronic device, instrument and meter and personal safety, possess the service that in than rugged environment, provides highly reliable.
3, outside sub-shield, woven density and reached the total shielding more than 90%, adopted this double layer screen, improved anti-interference from outside signals ability more, made transmission quality unaffected in particular surroundings.
4, (interior) external sheath layer is selected mechanical strength and resistance to wear height for use; Anti-dilatory, ageing-resistant, endurance, mould proof, anti-salt fog, fire-retardant, protection against rodents, outstanding low temperature flexibility and low coefficient of friction, the good environment-friendly type polyethers flame-retardant thermoplastic elastomer of hydrolytic resistance; This material does not receive the salt fog, mouse in the environment, moist influence, guarantees the stability of transmission quality.
5, be the electric wire product of protection against rodents, waterproof, anti-salt fog and fire-retardant a new generation of the supporting research and development of boats and ships detection system.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The anti-interference communication cable of double shield; Include the conductor 1 mutual stranded formation cable core of several wrap insulate layers 2, cable core is enclosed with lapping layer 3, sub-shield 4, inner restrictive coating 5, total screen 6, external sheath layer 7 outward successively, and sub-shield is that the tinned wird braiding constitutes with total screen; The sub-shield count is not less than 90%; Total screen count is not less than 93%, and count increases gradually, and shielding properties has obtained reliable assurance.
Insulating barrier 2 adopts the environment-protecting thermoplastic low smoke halogen-free flame-retardant polyolefin.
It is environment-friendly type polyethers flame-retardant thermoplastic elastomer that inner restrictive coating 5, external sheath layer 7 adopt material.
