Background technique
Servo cable is mainly used in industrial electronic system, automatically generates line, storage facilities, robot, metallurgical industry etc.
Field.In the related technology, the restrictive coating of servo cable is frequently with polyurethane or extraordinary PVC material extrusion forming.Due to using
Need to move repeatedly drawing servo cable in the process, and restrictive coating does not do reinforcement protection, often will appear sheath fracture, influences to make
With.
The removal cable design feature of existing market:
(1) reinforced using tensile materials braiding: primarily serving and increase cable core tension effect, so that cable entirety tension effect
Enhancing, but sheath is not strengthened, and sheath is easily broken off during the process that moves repeatedly or dragging, is caused inside cable insulation
Dampness or water inlet phenomenon, lead to security risk.
(2) filled using tensile materials: principle and (1) are identical, only play and increase cable core tension effect, so that cable is whole
The enhancing of body tension effect, but sheath is not strengthened, and sheath is easily broken off during the process that moves repeatedly or dragging, causes electricity
Cable insulating inner dampness or water inlet phenomenon, lead to security risk.
Reinforcement material frequently with steel wire or cotton thread as cable in the related technology.Intensity of steel wire is high, high temperature resistant, is squeezing
Out under 180~200 DEG C of head or so processing temperatures, do not soften, indeformable, shape is uniform, is easily worked, but flexible bad, meeting
Decline cable bend performance, should not use in removal cable.Cotton thread intensity is high, and flexibility is good, and shape is uniform, but heatproof is not
It is good, between softening point temperature 130~160, in the case where squeezing out 180~200 DEG C of head or so processing temperatures, it is easily broken off, it is bad to add
Work.
Summary of the invention
For present inventor by finding after repetition test, well-chosen, the tensile strength for spinning synthetic fibre silk is all fibres
In best, high temperature resistant, intensity is 5~6 times of steel wire, and weight is only 1/5 of steel wire or so, 560 DEG C at a temperature of, regardless of
Solution, it is non-fusible, there is good insulating properties and anti-aging property, 367~370 DEG C of softening point, squeezing out 180~200 DEG C of head
It is not broken under the processing temperature of left and right；And it is small to spin synthetic fibre silk outer diameter, and uniformly, the aramid fiber yarn of 1 1500D, tensile strength is in 300N
Left and right, outer diameter is in 0.10mm or so, it is easy to be added in sheath, and can combine very well with sheath, without influencing jacket surface
Quality and outer diameter.
The present invention is directed to solve at least some of the technical problems in related technologies.
For this purpose, aramid fiber yarn is extruded in sheath an object of the present invention is to provide a kind of servo cable, to increase
The tensile capacity of strong sheath avoids servo cable from moving repeatedly in use, causing security risk since sheath is broken.
A kind of servo cable according to an embodiment of the present invention, comprising:
Cable body；
Restrictive coating, the restrictive coating are located on the outer peripheral surface of the cable body；
Multiple spinning synthetic fibre silks, multiple spinning synthetic fibre silks are located on the restrictive coating, and each spinning synthetic fibre silk is along the restrictive coating
The axially extending and multiple synthetic fibre silk that spins along the circumferential apart from one another by arrangement of the restrictive coating.
Advantageously, each spinning synthetic fibre silk is equal to each spinning synthetic fibre silk and institute at a distance from the periphery wall of the restrictive coating
State the distance of the internal perisporium of restrictive coating.
Advantageously, multiple quantity for spinning synthetic fibre silk are eight.
Advantageously, eight synthetic fibre silks that spin are arranged along the circumferential uniform intervals of the restrictive coating.
Advantageously, the restrictive coating includes the inner restrictive coating of first time extrusion forming and the outer shield of second of extrusion forming
Jacket layer, multiple spinning synthetic fibre silks are located between the inner restrictive coating and the external sheath layer.
Advantageously, the thickness of the inner restrictive coating is equal to the thickness of the external sheath layer.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of servo cable according to an embodiment of the invention.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings it is described in detail a kind of servo cable according to an embodiment of the present invention.
Firstly the need of explanation, present inventor spins the anti-of synthetic fibre silk by finding after repetition test, well-chosen
Tensile strength is best in all fibres, high temperature resistant, and intensity is 5~6 times of steel wire, and weight is only 1/5 of steel wire or so,
At a temperature of 560 DEG C, do not decompose, it is non-fusible, have good insulating properties and anti-aging property, 367~370 DEG C of softening point,
It squeezes out under 180~200 DEG C of head or so processing temperatures, it is not broken；And it is small to spin synthetic fibre silk outer diameter, and uniformly, the virtue of 1 1500D
Synthetic fibre silk, tensile strength is in 300N or so, and outer diameter is in 0.10mm or so, it is easy to be added in sheath, and can tie very well with sheath
It closes, without influencing jacket surface quality and outer diameter.
As shown in Figure 1, a kind of servo cable according to an embodiment of the present invention, comprising: cable body 100, restrictive coating 200,
Multiple spinning synthetic fibre silks 300.
Specifically, cable body 100 is by soft copper conductor 101, insulating layer 102, high intensity PP rope 103, the light-duty nothing of reinforcement
