Definitions

  • the invention relates to a flexible electrical line for portable consumers having at least two each consisting of an electrical conductor and a surrounding insulation existing cores as Verseilieri which surround a core made of insulating material with extending in the longitudinal direction dents in which the stranding , are herumverseilt, and which are surrounded by a common sheath of insulating material ( EP 1041585 B1 ).
  • Such lines are used for example for connecting portable devices with a voltage or signal source.
  • Mobile devices may be, for example, cranes, machine tools and robots.
  • the cables must be mechanically strong, with a constant flexural strength for a long time. They should remain well bendable in a wide temperature range, for example, between -40 ° C and +80 ° C. If the lines are used, for example, as drag chain lines in automation technology, then they must also with larger lengths of up to 50 m movements with increased speeds of up to 5 m / sec in the horizontal direction and corresponding accelerations of up to 50 m / sec 2 on Survive unscathed. For example, "permanently" means up to 5 million bending cycles.
  • the well-known line after the above-mentioned EP 1041585 B1 is designed as a flexible power line, which has a central core, around the power core, at least one control line and at least one data line are herumversilt.
  • the core has a plastic central tension member over which a sheath of cross-linked material is mounted, in which for each umverseilte element one of the contour of the same adapted, is mounted over the entire axial length of the core extending indentation.
  • the invention has for its object to make the above-described line so that it maintains its functionality without damage even with greater length and movements with high speed and acceleration over time.
  • An essential element of this line is the lubricious coated, elastically compressible core, which is designed to be resistant to tension and resistant to compression.
  • the durably moved, for example, in a drag chain line withstands the permanently occurring tensile and compression loads without damage.
  • Such tensile loads can exceed values of 15 N / MM 2 to 20 N / mm 2 in the acceleration phase of up to 50 m / sec 2 for a cable which is freely movably arranged in a drag chain.
  • the deceleration phase of such a drag chain compression forces act on the line, for which to the specified Acceleration values analogue values apply.
  • the bending fatigue strength of the line is ensured by the core in the long term.
  • the core or the elastically compressible material of the layer of insulating material thereof completely fills the inner gussets between the stranding elements, wherein the stranding elements are pressed into the same and lie in corresponding dimples of the insulating material. This results in a stable guidance of the stranding and a compact construction of the line.
  • the stranding members are easy to slide on the same in the axial direction because of the sliding layer of the core, mechanical damage thereof can be excluded even after many bending cycles with high safety.
  • Fig. 1 is a flexible electrical line reproduced, which has a core K as a central element.
  • the core K consists of a centrally arranged non-metallic, tensile and compression stable support 1 and the same surrounding layer 2 of an elastically compressible and permanently elastic insulating material.
  • Around the core K are stranded four cores 3, 4, 5 and 6, of which the cores 3, 4 and 5, for example, energy wires and the core 6 may be a protective conductor.
  • the wires 3 to 6 are hereinafter referred to as "stranding 3 to 6". They are - regardless of other, yet to be explained layers - surrounded by a jacket 7 outside of insulating material, which consists for example of polyurethane.
  • the layer 2 of the core K is in the stranding of the stranding 3 to 6 pressed by the same in the radial direction.
  • K dents are formed in the core, as it is in the Fig. 1 and 3 is indicated.
  • the dents extend helically in the axial direction of the conduit.
  • the core K has accordingly Fig. 2 in its original form an approximately circular cross-section. Depending on the type and construction of the stranding elements 3 to 6, however, it can also have a different geometric shape, for example oval or rectangular.
  • the layer 2 of the core K may advantageously consist of a soft, gel-like thermoplastic elastomer (TPE-O) or of silicone or rubber, and also in foamed or cellular form.
  • the tensile and compression stable support 1 may advantageously consist of tensile strength fibers of aramid, glass or basalt.
  • the fibers are preferably completely embedded in a binder, for example in a polyester resin, in order to achieve the compression stability of the core K.
  • Such tensile and compression stable support 1 has a modulus of elasticity of 50,000 N / mm 2 to 100,000 N / mm 2 and a tensile strength of between 1000 N / mm 2 and 2000 N / mm 2 .
  • the layer 2 of the core K is surrounded by a sliding layer 8, the material of which has good sliding properties in relation to the stranding elements 3 to 6.
  • a sliding layer 8 are materials based on polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the sliding layer 8 produced in this way can subsequently be thermally treated in a heating zone equipped, for example, with infrared radiators. It adheres well to layer 2 and has a thickness advantageously between 5 ⁇ m and 25 ⁇ m.
  • a film of PTFE with a thickness of at least 25 microns can be wrapped around the layer 2 gapless.
  • a film is advantageously made of foamed PTFE, preferably a low density unsintered PTFE.
  • the sliding layer 8 is designed and arranged around the core K, that the elastic deformability of the layer 2 is not affected. On the other hand, the sliding layer 8 can follow any changes in shape of the layer 2 of the core K without problems.
  • the line according to the invention can according to Fig. 1 be equipped with an overall electrical screen 9, which is disposed above the existing of the stranding 3 to 6 soul.
  • a total screen 9 can be designed as a braid or as Umseilung.
  • To build the same tinned copper wires can be used in conventional technology. With particular advantage but wires are used with better resilient properties.
  • Such wires are advantageously tin-plated or nickel-plated copper-clad steel wires or high-strength chrome-nickel steel wires or tinned steel wires individually wrapped with tin-plated copper tapes.
  • an inner sheath 10 can be extruded around the stranding elements 3 to 6, around which a protective sheath 11 is formed, which is elastically compressible and advantageously consists of the same materials as the layer 2 of the core K.
  • the protective cover 11 is preferably surrounded by a thin sliding layer on which the overall screen 9 can slide well when moving the cable. It is advantageously constructed in the same way as the sliding layer 8 of the core K. Over the overall shield 9 of the aforementioned sheath 7 is attached.
  • the line according to the invention can according to Fig. 3 be executed for example as a supply line for servo drives.
  • a line has in addition to the related Fig. 1 explained stranding elements 3 to 6 (wires 3 to 6) as an additional stranding a shielded signal line 12.
  • the signal line 12 consists of two signal wires 13, which are surrounded by two filling elements 14 by an electrically effective screen 15.
  • the screen 15 is designed, for example, as a braiding or braiding of tinned or silver-plated copper wires. Before attaching the screen 15, a thin sliding layer made of a material is expediently formed around the signal wires 13, on which the screen 15 can slide well.
  • a film of PTFE is preferably used, which is formed around the signal wires 13 gapless.
  • Particularly suitable is a foamed, unsintered low density PTFE.
  • the Signal line 12 is pressed into the layer 2 of the core K.
  • the other structure of the line after Fig. 3 corresponds to that for the line after Fig. 1 described construction.
