Two-by-two after pair twist, then whole stranding constitutes cable inner core with filling cotton yarn filling rounding；Between cable inner core and cable jacket
It includes inner sheath and oversheath to draw anti-interference layer and tinned copper wire shielded layer, the cable jacket equipped with high intensity aluminium foil wheat.
Preferably, the conductor is to add the compound superfine annealed copper wire of strand of anti-elater.
Preferably, the high flexibility insulation is that high flexibility thermoplastic polyester elastomer insulate.
Preferably, the inner sheath and oversheath are high elasticity abrasion-proof damage polyurethane thermoplastic elastomer sheath.
The robot arm of the utility model high flexibility high life drag chain cable, not only anti-tampering and shield effectiveness is good,
With better fire-retardant, water-fast, oil resistant, low temperature resistant, weather-proof, ozone resistance, the various complex environments that robot uses are adapted to,
Especially in resistance to torsion, resistant to bending, wear-resistant, more prominent in terms of service life, alternating bending frequency is more than 3000 in drag chain
Ten thousand times, bending property is more preferable, and the service life is longer, and use scope is wider.
The characteristics of the utility model, sees the detailed description of this case attached drawing and following preferable embodiment and obtains clear
Ground understands.
Description of the drawings
Fig. 1 is the structural schematic diagram of the robot arm high flexibility high life drag chain cable of the utility model.
Wherein, 1, conductor；2, high flexibility insulate；3, cotton yarn is filled；4, high intensity aluminium foil wheat draws anti-interference layer；5, tin-coated copper
Silk shielded layer；6, inner sheath；7, oversheath.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
The utility model is expanded on further in face in conjunction with specific embodiments.
As shown in Figure 1, a kind of robot arm high flexibility high life drag chain cable, including outside cable inner core and cable
Set.
Cable inner core includes insulation core wire and filling cotton yarn 3, and insulation core wire includes the high flexibility of conductor 1 and conductor outer cladding
Insulation 2, insulation core wire is two-by-two after pair twist, then whole stranding, fills rounding with filling cotton yarn 3, constitutes cable inner core.
Conductor is to add the compound superfine annealed copper wire of strand of anti-elater.Conductor selects superfine soft copper monofilament, after first bundle strand 7 strands it is regular
Structure twists again, when bundle strand the per share anti-elater 3 of addition 250D, cable-former is furnished with back-twist device when twisting again, can eliminate multiple strands generation
Stress, make wire rod more rounding, it is soft, ensured that copper wire is not broken after cable is moved back and forth at 30,000,000 times.
High flexibility insulation 2 uses high flexible TPEE (thermoplastic polyester elastomer) Insulation Material resistant to bending, TPEE to belong to
In high-performance engineering grade elastomer, there is good high mechanical strength, elasticity, shock resistance, creep resistance, cold-resistant, bending fatigue resistance, resistance to
The advantages that oil, chemical-resistant resistance and solvent corrode has good processability, so that the material is become multiple repeated loading and uses item
Ideal material under part.Cable can be made to meet the requirement of up to 30,000,000 times reciprocating motions.And it is with excellent heat resistance
Can, it can be used in -70 DEG C~200 DEG C operating temperatures.
It fills cotton yarn 3 and is used as packing material, the construction of cable more rounding, softness can be made.And play cable reciprocating motion
The frictional force between cable is buffered in the process.
Core wire pair twist and stranding and wrapped：Using cage winch, pair twist tooling is added before the forming, by pair twist process and stranding
Process is unified, be mesh avoid pair twist node from overlapping one side laying up diameter is smaller, and one side node is misaligned, when torsion
Will not influence each other leads to stress concentration point.And it is wrapped using aluminium foil in stranding, the cross-talk mitigated in signal transmission is played, is prevented
The only effect of outer signals interference.
It is equipped with high intensity aluminium foil wheat between cable inner core and cable jacket and draws anti-interference layer 4 and tinned copper wire shielded layer 5.It compiles
Knit the tin plating soft copper silk of shielded layer and be interweaved and be covered on wire products, become one layer of close protective layer with after stranding around alclad
Foil equally plays shielding and uses, and prevents other signals from being had an impact to the signal of cable transmission.
Cable jacket includes inner sheath 6 and oversheath 7.
Inner sheath and oversheath are high elasticity abrasion-proof damage polyurethane thermoplastic elastomer sheath.Its mechanical performance, electrically
The performances such as energy, wear-resisting, oil resistant, weather-proof, fire-retardant protrude, and glass transition temperature is relatively low, and good bullet is still kept in 40 degrees below zero
Property, compliance and other physical properties.Outer to use two layers of extrusion mode by extrusion, while ensureing wire rod rounding, oversheath is adopted
With the method for hollow extrusion make it is outer be formed as tubulose, play reserving certain space to internal core and prevent excessive friction from damaging core
Line further increases the flexibility and service life of wire rod entirety.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model the utility model also have respectively
