The high-elasticity bending-resistant cable is good in bending performance and good in high-frequency signal transmission effect.
Description
The technical field is as follows:
the utility model relates to a cable, specifically say that a high elasticity is able to bear or endure to bend cable.
Background art:
in cables used in the electric power communication and petroleum and petrochemical industries, high requirements are provided for the bending performance of the cables, and particularly, signal attenuation is easy to occur after bending, so that the transmission of high-frequency signals is affected. After bending, the elongation rate is reduced, and even the circuit is broken.
The utility model has the following contents:
the utility model aims to solve the technical problem that a high elasticity cable of bending that the performance of buckling is good, elasticity is high is provided, this high elasticity cable of bending is difficult for the degeneration of percentage elongation in the use, and the compliance is good.
The technical solution of the utility model is, a high elasticity cable of nai bending is provided, including the conductor, the conductor includes 1 zinc silk that is located the center, and the zinc silk is equipped with nickel coating and copper plate outward in proper order, and the conductor still has high temperature resistant layer and outer insulating layer including 6 copper nickel plating wires around the copper plate coiling outward in proper order, the cladding in proper order outside the conductor.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: plating nickel outside the zinc wire to improve the oxidation resistance of the wire and the binding force of a copper layer; the arrangement of the copper plating layer can match with current density and speed to obtain good conductivity and transmission performance; the wire rod cannot be hardened and embrittled when the drawing process is carried out, the elongation, the flexibility and the bending resistance of the wire rod are superior to those of copper, aluminum and steel, the elongation is not easy to degrade and cannot be broken, the copper-plated wire rod can play an anti-corrosion effect on copper wires and simultaneously enhance a signal transmission effect by combining a copper-plated layer and wound copper nickel plating outside the zinc wires.
Preferably, the high-temperature resistant layer is made of a polyurethane material, the outer insulating layer is made of a polyolefin halogen-free flame-retardant radiation-free material, and the thickness of the outer insulating layer is half of that of the high-temperature resistant layer.
Preferably, an elastic wire is further arranged between the high temperature resistant layer and the conductor, and the elastic wire is formed by twisting a plurality of glass fiber filaments.
Preferably, the nickel plating layer is uniformly distributed on the peripheral surface of the zinc wire at intervals.
Furthermore, the zinc wire is a zinc wire with 99% of zinc content. The zinc wire has the advantages of good elongation percentage, good flexibility, bending resistance and good corrosion resistance.
Description of the drawings:
fig. 1 is a schematic cross-sectional view of an embodiment of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in fig. 1, a high-elasticity bending-resistant cable comprises a conductor, wherein the conductor comprises 1 zinc wire 1 located at the center, a nickel plating layer 2 and a copper plating layer 3 are sequentially arranged outside the zinc wire 1, the conductor further comprises 6 copper nickel plating wires 4 wound around the copper plating layer 3, the conductor is sequentially coated with a high-temperature-resistant layer 5 and an outer insulating layer 6, in the embodiment, the high-temperature-resistant layer 5 is made of a polyurethane material, the outer insulating layer 6 is made of a polyolefin halogen-free flame-retardant radiation-free material, the thickness of the outer insulating layer 6 is half of the thickness of the high-temperature-resistant layer 5, the elasticity and the flexibility are good, the diameter of the zinc wire 1 is 3-6mm, the thickness of the nickel plating layer is 0.3-0.5mm, the thickness of the copper plating layer is 0.3-0.5mm, and the thickness. In order to reduce cost and be suitable for bending, the nickel-plated layers 2 are uniformly distributed on the outer peripheral surface of the zinc wire 1 at intervals, the nickel-plated layers 2 form 8 cm-long plating sections on the zinc wire 1, and the distance between every two adjacent nickel-plated layers 2 is 5 cm. In order to improve the strength, an elastic wire 7 is arranged between the high temperature resistant layer 5 and the conductor, and the elastic wire 7 is formed by stranding a plurality of glass fiber filaments. In the embodiment, the zinc wire 1 is a zinc wire with 99% of zinc content, and the zinc wire with the specification has the advantages of good elongation, good flexibility, bending resistance and good corrosion resistance.
