Abstract
The utility model discloses a corrosion-resistant and cold-resistant control cable. The cable comprises four inner conductors and a plurality of outer conductors. A fluoroplastic insulating layer is wrapped outside each of the four inner conductors so that four inner insulating cores are formed, and a fluoroplastic insulating layer is also wrapped outside each of the outer conductors so that a plurality of outer insulating cores is formed. The four inner insulating cores are intertwisted and clustered and then are wrapped in an elastic layer which is molded by a thermoplastic elastomer through plastic extrusion. After the plurality of outer insulating cores is evenly arranged outside the elastic layer, a cable core is formed. A taped layer, a copper wire woven shielding layer and a silicone rubber sheath layer are successively wrapped outside the cable core. The corrosion-resistant and cold-resistant control cable is reasonable in structure and design. The inner conductors of the cable are molded through plastic extrusion and then are placed in an anti-press layer, such that the cable is enhanced in terms of resistance to external extrusion. Moreover, the cable core is not liable to be damaged, information transmission is guaranteed to be smooth, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to control cable, relates in particular to a kind of anticorrosion cold-resistant control cable.
Background technology:
The soft control cable of using is manufactured the technological process of this type of soft control cable according to GB/T9330-2008 at present: conductor bundle strand-insulating exruded-stranding-extrude sheath, roughly four technologies are crossed and are become to finish.
Adopt the soft control cable bending radius of above-mentioned technology bigger (be not less than the outside diameter of cable 6 times), do not satisfy the installation needs of small space sometimes, bending radius is too small can the damage cable, influences the normal use of product.Because this type of soft control cable flexibility is not fine, frequently move around or crooked occasion shorter useful life, in use the cable conductor frangibility causes cable breakdown or broken string accident.
In addition, cable is easily disconnected core when most importantly the conductor in the cable core is squeezed, and it is impaired to make that cable transmits information, and how to address this problem is present problem demanding prompt solution.
The utility model content:
At the deficiencies in the prior art, the purpose of this utility model provides a kind of anticorrosion cold-resistant control cable, and the structural design novelty has improved the anti-extraneous extrusion capability of cable, protects cable core injury-free effectively.
The technical solution of the utility model is as follows:
Anticorrosion cold-resistant control cable, comprise four inner wires, several outer conductor, it is characterized in that: described four inner wires, several outer conductor outside are enclosed with the fluoroplastic insulation layer respectively and constitute four interior insulated wire cores, several external insulation core, outsourcing is wrapped in the elastic layer of thermoplastic elastomer (TPE) extrusion moulding behind four stranded bunchys of interior insulated wire cores, elastic layer constitutes cable core after being evenly distributed with several external insulation cores outward, and cable core is provided with lapping layer, copper wire woven shield, silicone rubber jacket layer outward successively.
Described anticorrosion cold-resistant control cable is characterized in that: described lapping layer adopts the high-temperature fibre band overlapping wrapped, and the wrapped rate of putting up is not less than 50%.
The utility model has the advantages that:
The utility model reasonable in design is positioned in the resistance to compression layer through extrusion moulding by the inner wire with cable, has improved the anti-extraneous extrusion capability of cable, and cable core is difficult for impaired, and it is unobstructed that guarantee information is transmitted, and increases the service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
