Fig. 2 is the schematic diagram in the present invention before conductor-stretch；
Fig. 3 is the schematic diagram after conductor-stretch shown in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, Fig. 2 and Fig. 3, flexible robot's cable of one of present invention, including multiply conductor, multiple polyvinyl chloride insulation layer 3, shielding layer of copper wires 4 and PUR sheath 5.
Owing to the present invention is applied in super flexible robot, therefore the conductor that soft structure weaves need to be used, simultaneously weaving and increase its resist bending and weight capacity for convenience, per share conductor is by Fanglun 1414 1 and is placed in many copper free wires 2 of this Fanglun 1414 1 outer layer and carries out the count braiding more than 90% via braider and form.This structure can be effectively improved the draftability of whole conductor, tensile strength, flexibility and signal of telecommunication transmission performance, and conductor can shrink when stress as netted.Weave speed during braiding, the tension force of count line the most strictly controls.In the present embodiment, conductor is carried out the count braiding more than 90% formed by copper free wire and the Fanglun 1414 that equivalent diameter is 0.44mm of 20 a diameter of 0.08mm.It is 0.76mm that conductor calculates external diameter.
Each polyvinyl chloride insulation layer 3 is respectively coated by each conductor to form each core.In the present embodiment, use insulating exruded equipment, the high-performance poly vinyl chloride insulation layer that one layer of nominal thickness is 0.15mm outside conductor, will be extruded.It is 1.06mm that this core calculates external diameter, and during extrusion, the strict outside dimension that controls fluctuates.
Shielding layer of copper wires 4 is coated with all cores.In the present embodiment, shielding layer of copper wires 4 is carried out the count braiding not less than 85% by the copper free wire of many a diameter of 0.08mm and forms.
PUR sheath 5 coated copper wire screen layer 4.In the present embodiment, PUR sheath 5 thickness 1.0mm, finished product external diameter is 4.88.
The manufacture method of flexible robot's cable of the two of the present invention, comprises the following steps:
One, manufacture conductor, Fanglun 1414 1 is placed in center, more copper free wires 2 are placed in the outer layer of Fanglun 1414, then carry out count via braider and be knitted to form conductor more than 90%.Conductor can be flexible as netted when stress, will not be lost because of stretching stress, deform.
Two, manufacture core, outside conductor, extrude a strata vinyl chloride insulation layer 3 by insulating exruded equipment, form core.
Three, manufacture the shielding of cable, use braider closely to weave the last layer count shielding layer of copper wires 4 more than 85% to multiply core；
Four, PUR sheath 5 is extruded out at shielding layer of copper wires 4 outer employing sheathing machine.
To sum up, the big I of radical of the Fanglun 1414 1 in conductor is adjusted according to the requirement of the stretching frequency, tensile force, current-carrying capacity and the line footpath size of the robot cable of institute's use occasion.Conductor strictly controls Fanglun 1414 1 and the rounding property of knitted conductor and external diameter, it is ensured that the rounding property of conductor and degree of compaction, to improve the draftability of product, expansion and contraction, warp resistance and current-carrying capacity.Sheath uses PUR to be closely coated with, and improves the wearability of product, acid-alkali-corrosive-resisting and warp resistance.
Above example is used for illustrative purposes only, rather than limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, the technical scheme of the most all equivalents also should belong to scope of the invention, should be limited by each claim.
