Definitions
- the present invention relates to an electrical line according to the preamble of Claim 1.
- Electrical cables for connecting portable electricity consumers must be flexible and therefore have a fine or depending on the flexibility requirement fine-wire conductor.
- the diameter of the wires is particularly important for the stranding structure of the conductor. ever the shorter the stranding of the stranded wires and strands, the higher the mobility and fatigue strength.
- a method for producing a stranded conductor is known from when threading several individual wires together, a thread made of glass fiber twine with being stranded.
- the thread made of fiberglass thread is said to be used for strong gagging and high production speeds, adverse effects on the balance the mechanical properties of the copper wires.
- Glass silk twine has one around about five times higher tensile strength than a soft copper wire and an elongation at break of approx. 2% compared to an average elongation of 25 to 35% for copper wires.
- the Thread made of glass silk thread therefore absorbs all the tensile parameters that occur, both occur in the manufacture of the stranded conductor as well as in later practical use can.
- a disadvantage of this solution is that the electrically conductive cross section of the stranded conductor is reduced. Often it is not accepted that a there is no metallic element in the strand.
- Another proposed solution was to build a stranded wire in such a way that one hard drawn copper wire, soft copper wires were roped around. In this way could the tensile strength, the fatigue strength and the behavior of the strand Crimping process can be improved. These strands could be used for extreme applications but also not convincing.
- the present invention has for its object the known electrical To improve lines so that these compared to the previously known Cables have a significantly higher fatigue strength at lower costs.
- the line according to the invention by a line made of copper-cadmium or. Copper-tin alloys have comparable higher tensile strength.
- the electrical Conductivity is only slightly less than with a stranded wire of the known type.
- FIGS. 1 and 2 Exemplary embodiments explained in more detail.
- Figure 1 shows a section through an electrical line z.
- B. a sensor line from there are two wires 1 and 2 and a jacket 3 surrounding wires 1 and 2.
- each Core has a conductor 1a or 2a and core insulation 1b or 2b.
- the coat 3 is preferably an extruded polyurethane jacket.
- the core insulation 1b or 2b can consist of thermoplastic or cross-linked insulating materials. Prefers are cross-linked polyethylene, polyurethane and two-layer insulation such as is described for example in the earlier application 100 36 610.4.
- the conductor 1a or 2a is a multi-stranded strand, as shown in Figure 2.
- the strand 1a, 2a consists of seven wire bundles 4, with six wire bundles as a layer are stranded around a central wire bundle.
- Each wire bundle 4 has an inner one Core wire 5, around which six individual wires 7 are stranded.
- the individual wires 7 are preferably with alternating lay direction - in cable technology SZ stranding called - stranded.
- the core wire 5 is made of a material with high tensile strength and flexural fatigue strength.
- a chromium-nickel steel with a strength of 1770 N / mm 2 is preferably used.
- the individual wires 7 are copper wires which have a strength of approximately 280 N / mm 2 .
- a conductor shown in Figure 2 can be produced in one step, in which first by means of seven SZ stranding devices made of core wire 5 and Copper wires 6 existing wire bundles 4 are produced.
- the seven wire bundles 4 are then passed through a stranding nipple and wound on a rotating rewinder. By rotating the rewinder the wire bundle 4 stranded together to form the multi-wire conductor 1 a, 2a.
- Electrical lines according to the teaching of the invention can be used in the automotive field medical technology but also find application in compressor refrigerators.
- Typical dimensions of a line according to the invention are: Core wire diameter 0.12 mm Diameter copper wire 0.11 mm lay length 4.0 mm Lay length of the wire bundle 11.8 mm Outside diameter of the conductor 1.02 mm production speed 30 m / min
