Detailed Description

As shown in fig. 1, a high flexibility pair-twisting shielding data drag chain cable, including tinned copper core soft strand stranded conductor 1, crowded package has silicon rubber insulating layer 2 outside tinned copper core soft strand stranded conductor 1, the winding has polytetrafluoroethylene film 3 outside silicon rubber insulating layer 2, with two tinned copper core soft strand stranded conductor 1 pair twists the back, place an aramid fiber silk 4 respectively in both sides to woven tinned copper wire branch shielding layer 5 in the outside the tinned copper wire branch shielding layer 5 outside extrusion have soft polyvinyl chloride sheath 6 to constitute the sinle silk, strand many sinle silks into the cable core, extrude soft polyvinyl chloride inner sheath 7 outside the cable core, woven tinned copper wire shielding layer 9 outside soft polyvinyl chloride inner sheath 7, evenly placed four aramid fiber silks two 8 in tinned copper wire shielding layer, and the cladding has oversheath 10 outside tinned copper wire shielding layer 9.

The outer sheath 10 is an extruded PUR polyurethane outer sheath.

And twisting the four wire cores into a cable core.

The high-flexibility twisted-pair shielding data drag chain cable provided by the utility model adopts a tinned copper core soft strand twisted conductor, silicon rubber is extruded for insulation, a polytetrafluoroethylene film is wound outside an insulating layer, each two cores are twisted in pairs, aramid filaments I are respectively placed on two sides of each twisted-pair wire core, a tinned copper wire sub-shielding layer and a total shielding layer are woven, and a soft polyvinyl chloride protective layer and a PUR polyurethane material outer protective layer are extruded. Flexibility and flexibility are fully considered in the overall structural design of the cable, the insulating layer is protected, and the service life of the product can be effectively prolonged. The high-flexibility cable is suitable for industrial automation equipment such as mechanical arms, woodworking machines, glass machines, cutting machines, ceramic machines, spraying machines and the like, is used for an ideal cable of a drag chain, and is suitable for all areas needing frequent movement and rapid bending, including dry or humid rooms of all high-speed moving machine parts such as numerical control machines, robotics and the like. The sinle silk is to the hank, reduces the electromagnetic interference between the inside sinle silk of cable by a wide margin, and the shielding is woven to the tinned copper wire makes the cable have stronger anti external electromagnetic interference ability, guarantees cable system's stability. Extremely small bend radii may be desirable for use in a drag chain system. Is suitable for outdoor laying and is resistant to ultraviolet rays, oxidation, ozone and hydrolysis.

The product adopts super six types of multi-strand tinned copper core stranded soft conductors, and ensures that the cable has high softness and high conductivity. The insulating layer of product chooses the silicon rubber material for use, the silicon rubber not only has better insulating properties, its compliance is that other materials are incomparable, for preventing that the insulating layer from appearing damaging in long-term crooked in-process, overlap around the package one deck polytetrafluoroethylene film outside the insulating layer, this material has higher insulating properties, and is soft, high temperature resistant, play the guard action to the insulating layer in addition, even the insulating layer appears the damage, should can play insulating properties around the package equally, the life of product has effectively been improved. Every two insulation core carry out the pair twist, respectively put an aramid fiber silk one at two sides after the transposition, weave tinned copper wire branch shielding layer, the aramid fiber silk is a novel high-tech synthetic fiber, has super high strength, high-modulus and high temperature resistant, acid and alkali resistant, excellent properties such as light in weight, and its intensity is 5 ~ 6 times of steel wire, plays effective tensile and guard action for the cable in the use of warping repeatedly. The weaving density of the sub-shielding layer is controlled to be more than 85 percent so as to ensure higher anti-interference performance. The braided twisted wire core extrudes the soft polyvinyl chloride protective layer, the thickness is controlled to be 0.4mm, and the outer diameter of the product is controlled. And then, performing cabling and stranding on the cable cores after each pair of stranded and extruded protective layers, wherein filling materials are not used during stranding, and only non-woven fabrics are adopted for performing pattern winding to tighten the stranded cable cores. The inner protection layer is made of soft polyvinyl chloride plastics, the extrusion process is utilized, non-woven fabrics which are subjected to pattern winding on the cable core are taken off when the inner protection layer is extruded, and the extruded soft polyvinyl chloride plastics directly fill the gaps of the cable core, so that the cable core is very tight. The shielding layer is woven by adopting the tinned copper wires outside the inner protection layer, the weaving density is controlled to be more than 85%, and the four aramid fibers II are uniformly placed in the shielding layer, so that the tensile property of the product is improved. The outer sheath is made of polyurethane, and the PUR has the characteristics of wear resistance, softness, good weather resistance, excellent oil resistance, good toughness, wear resistance, cold resistance (low temperature resistance), water resistance, aging resistance, acid and alkali resistance, weather resistance, long service life, ultraviolet resistance, energy release and other excellent functions as those of rubber. The product has high flexibility, high toughness, bending resistance and distortion resistance, and effectively prevents the internal core breaking of the cable under the condition of frequent bending. The whole high shielding density of weaving and special structural design, the effectual external interference of resisting and the inside interference of cable have guaranteed signal transmission's stability. The tensile design of the product enables the product to bear tensile stress uniformly, and ensures that the cable does not break after long-term effective work.
