Description
Technical field
This utility model relates to field of cable technology, particularly to the digital signal transmission cable in intelligent robot system.
Background technology
Along with the development of intelligent robot technology, the application of robot constantly expands extension, and plays increasing effect in the life and commercial production of people.Intelligent robot, in the application in the fields such as industry, agricultural, space flight, military affairs and medical science, has liberated labour force greatly, completes the excessive risk task that many people cannot complete.
Intelligent robot can complete many complicated work, the work of these complexity needs the movable parts such as robot arm constantly to bend and twist motion, and the digital signal transmission cable being installed in robot system allows for standing bending frequently and extruding force and twisting resistance produced by the teamwork such as torsion, therefore robot cable does not require nothing more than and has higher wearability and anti tear requirement, and there is fabulous softness requirements, the signal conveying capacity that so guarantee robot cable is powerful, guarantee robot plays preferable function.The applicant has applied for the utility model patent (application number: 201620079897.6) of " high antitorque robot signal cable " on January 27th, 2016, the signal cable of this application has preferable anti tear and anti-wear performance, but flexibility is not enough in actual use, and between each loom unit of composition cable core, easily form mutual signal disturbing and cross-talk, it is unfavorable for the safe transmission of signal and the properly functioning of robot.
Utility model content
Technical problem to be solved in the utility model is to provide one and can effectively prevent electromagnetic wave from invading and leaking, and has again the soft high secure digital signal cable of height of preferable flexibility.
In order to solve above-mentioned technical problem, the soft high secure digital signal cable of height of the present utility model, anti-skidding belting layer, inner sheath, cable core screen layer and the oversheath including cable core and being coated on cable core, described cable core is made up of core bundle and fiber strands, is coated with conductor screen and core insulating barrier on this core bundle successively；Described core bundle includes that intentionally portion's wire harness and stranded outer layer wire harness on heart portion wire harness, heart portion wire harness and outer layer wire harness are by some stranded bunchys of copper monofilament；The bundle strand direction of outer layer wire harness is in opposite direction with the bundle of heart portion wire harness strand, and the multiple strand direction of the outer layer wire harness layer being made up of six roots of sensation outer layer wire harness is identical with the bundle of outer layer wire harness strand direction.
After using said structure, owing to the heart portion wire harness of core bundle and outer layer wire harness are by some stranded bunchys of copper monofilament, in this structure, core bundle is not to use single conductor, but formed by some very thin tinsels are stranded, both can guarantee that the safe and reliable transmission of digital signal, make again cable core have splendid flexibility, it is simple to cable bend and torsion, more can preferably avoid producing extruding and twisting resistance because of bending and torsion to harmful effect produced by cable.Again owing to have employed core shielding and the dual shield structure of cable core shielding, core shielding construction the most effectively stops electromagnetic interference signal to invade core bundle screen unit, also the internal electromagnetic signal radiation of core screen unit is avoided to leak, cable core shielding construction the most effectively stops the impact on cable core of the external electromagnetic interference signal, there is the tightest shield effectiveness reliably, it is ensured that the security reliability of cable transmission signal.Due also to restraint strand direction with it identical in the multiple strand direction of outer layer wire harness, so beneficially the stress of every copper monofilament and degree of crook in uniform wire harness during multiple strand, more can realize very thinization of cable core monofilament, thus improve the flexibility of whole cable.And the bundle strand direction of outer layer wire harness is in opposite direction with the bundle of heart portion wire harness strand, the equilibrium of core bundle every copper monofilament stretching force can not only be realized, monofilament is avoided to rupture in pulling process, and the stranded compactness of monofilament and core bundle has been effectively ensured, avoid pine stock, prevent being excessively embedded of monofilament and adjacent lines interfascicular, it is ensured that the bending of wire is flexible.Owing to cable core is made up of core bundle and fiber strands, core bundle in cable core is filled in fiber strands, on the one hand fiber strands ensure that core bundle position in cable core, ensure that the rounding of cable core is stable, thus enhance the electrical property of cable, on the other hand fiber strands has again higher tensile resistance, makes cable have good tension and antitorque effect, it is ensured that core Shu Buhui occurs because of distortion mutually to extrude the breakage caused.
Conductor screen described in preferred implementation of the present utility model is foil screen layer, and described cable core screen layer is netted woven shield.The foil screen layer of described conductor screen is wrapped by plastic-aluminum shielding band, and the netted woven shield of described cable core screen layer is formed by tin plating soft proof copper-wire braided.This structure is easy to fabrication and processing, and shield effectiveness is good.
Further embodiment of the present utility model, described core bundle is filled in fiber strands, and this fiber strands is chemical fiber filament.It is strong that chemical fibre has pulling force, does not goes mouldy and the superperformance of corrosion resistant.
Further embodiment of the present utility model, described core insulating barrier is that PET mixture extrudes layer, and described oversheath is that polyester compound extrudes layer.Using PET mixing to extrude layer, its electrical insulation capability is excellent, and even in the case of high-temperature high-frequency, its electrical property is still preferable, and endurance, mar proof and good stability of the dimension.
