Description
Technical field
The present invention relates to a kind of data cable, more particularly to a kind of antistatic shielding data cable.
Background technology
The structure of traditional shield type data cable is wrapped one layer of polyester belt to gathering by 4 groups of symmetric signal lines, then
The wrapped one layer aluminium-plastic tape for being used to shield, outer layer extrusion PVC or other plastic covering layers.Symmetric signal is to being by two copper
The insulated wire set that high-density polyethylene layer is coated with outside conductor forms.The specification that properties of product meet TIA/EIA568 will
Ask.To solve electric property attenuation problem and electromagnetic interference problem under lower frequency, some product designs are in aluminium-plastic tape
One layer of brass wire shielding of outer braid.For requiring mobile shield type data cable, the conductor of symmetric signal pair is replaced by more
Root copper stranded conductor.The data cable of this kind of structure can ensure transmission performance in fixed laying and mobile occasion use.But
It is in the environment of mechanical arm etc. frequently movement, environmental condition rather harsh, the performance reliability of such product cannot expire
Foot requires, by the movement of hundreds of times, the problems such as conductor break, decay increase, interference free performance decline just occurs.In movement
During, friction be present between insulation, between insulation and outer layer band, shielding, on the one hand easily produce electrostatic, cause signal
Interference, while frequently rubbing can also cause the mechanical and physical performance of insulating materials to decline.In general mechanical arm can all require 10
The movement of more than ten thousand times, if the influence of the slip of cable core structure can not be solved, it is impossible to solve product endurance and shielding is stable
The problem of property, the signal transmission demand of mechanical arm cannot be ensured.In this point, traditional cable structure is it is difficult to ensure that conform to
Ask.
A kind of data cable how is designed, signal transmission guarantor during the type frequently reciprocating of more than 100,000 times can be ensured
Card is stable, turns into the direction of those skilled in the art's effort.
The content of the invention
The present invention provides a kind of antistatic shielding data cable, and this antistatic shielding data cable coefficient of friction is small, soft
Stretch-proof, produce without frictional static, it is frequently mobile after still can guarantee that constitutionally stable data cable, cable tensile strength carries

Eight copper conductor units are twisted form the symmetrical insulated wire pair of first, second, third and fourth and respective appearance two-by-two
Face is surrounded with the first teflin tape, and the symmetrical insulated wire pair twist of first, second, third and fourth is together in the aramid fiber
Reinforcer outer surface forms cable core；
The vertical bag cable core outer surface of one second polytetrafluoroethylene floor, second polytetrafluoroethylene floor and first, second, third
And the 4th gap between symmetrical insulated wire pair be filled with some cotton yarns；
Some one metal wires are abreast wound in the second polytetrafluoroethylene floor outer surface and form metal screen layer, this metal screen
Cover wire outer surface in layer and be surrounded with the 3rd teflin tape, this 3rd polytetrafluoroethylene (PTFE) belt winding direction and the cotton
Single winding direction is opposite；
One the 4th teflin tape is vertical to be wrapped in the metal screen layer outer surface；
One external sheath layer is coated on the 3rd polytetrafluoroethylene floor outer surface；
The cotton fiber line is dredged and is around in the second polytetrafluoroethylene floor outer surface；
The superposition that 3rd teflin tape is wound in wire junction is placed；
The a diameter of 200D of aramid fiber reinforcer.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. the antistatic shielding data cable of the present invention, the symmetrical insulated wire of its first, second, third and fourth is to respective outer surface
It is surrounded with the first teflin tape and is twisted and forms cable core, the vertical bag cable core outer surface of the second polytetrafluoroethylene floor,
Frequently in BENDING PROCESS, overcome between the symmetrical insulated wire of first, second, third and fourth and respective copper conductor unit
Distance and pitch change, so as to cause the change of electric property；And frequently in BENDING PROCESS, first, second, third
Be surrounded with the first teflin tape to respective outer surface with the 4th symmetrical insulated wire, and the second polytetrafluoroethylene floor pass through it is vertical
Symmetrical insulated wire pair of the packet mode cladding with four the first teflin tapes, because the first teflin tape and second gather

Category silk has enough shift positions to cause to break without producing stretching, while is easier to slide without producing between adjacent wire
Electrostatic interference, the structure both can guarantee that the pliability of cable, also ensure that the shield effectiveness after being frequently bended；On the other hand, its
Avoid in the reciprocating motion of cable, produce electrostatic interference between oversheath and screen layer wire, improve electric property；Together
When, the performance comparision of teflin tape is soft, smooth, does not interfere with the pliability of cable, and smooth surface causes curved
Slip is easily produced during song between cable core, metal screen layer and outer jacket, reduces stretching of the external force to cable, extends and use
Life-span.
3. the antistatic shielding data cable of the present invention, its copper conductor unit includes the aramid fiber positioned at center, by some
Root is twisted the inner conducting layer in the first copper conductor composition of aramid fiber outer surface, is twisted by some second copper conductors and is led in interior
Electric layer outer surface forms outer conductor layer, improves tensile strength, ensure that aramid fiber in the steady of construction of cable center
It is fixed；The symmetrical insulated wire pair twist of first, second, third and fourth forms cable core together in an aramid fiber reinforcer outer surface；It ensure that electricity
Cable structure is stable so that the tensile strength of product improves 50%, and counter-bending number lifts 300 ~ 500%, 10000 bending decay
Changing value is less than 2%.
4th, the shielding data cable of the suitable alternating bending of the present invention, its cable core stranding direction, cushion winding direction, shielding
Layer direction is successively on the contrary, form relatively parallel disc, the phase that is unlikely to be embedded in internal layer in bending and influences between different coverings
To sliding, so as to reduce the pulling force of cable core, bending resistance is improved.Different polytetrafluoroethylene (PTFE) band lapping directions and internal layer
Stranding or wire winding direction are on the contrary, can ensure the rounding of structure.So that the force of sliding friction of different interlayers is reduced to most
It is small, destruction when reducing cable bend to the construction of cable, so as to improve bend performance, attenuation change when reduction is frequently bended
Rate.
