Definitions
- the invention relates to a multi-layer foamed electric cable with a specific jacket structure and a method for manufacturing such a cable having such a jacket structure.
- the invention relates to a sheathed electrical line, comprising at least one electrical conductor with insulation and a sheath structure made of plastic.
- a line from the prior art that has long been known DE 30 05 615 A1 relates to an electrical flexible cable with a flexible basic cable made of a foamed material with a large pore volume, preferably based on PUR, which is wrapped in a spiral shape and a coaxial PUR plastic jacket is applied on the outside.
- the cable can be used in particular for anti-lock braking systems and sensors for speed measuring systems in motor vehicles and has proven itself in practice.
- the cable has a sheath made of polyurethane.
- the jacket consists in particular of PP, that is to say of polyether polyurethane, with a specific Shore hardness. This hardness is advantageously in the range of 75 to 95 Shore A.
- EVA ethylene-vinyl acetate copolymer
- the utility model mentioned also provides for the insulation of the conductor itself to be made from polyurethane, with this having a Shore D hardness in the range from 55 to 64.
- This polyurethane material is, in particular, a thermoplastic material that can be melted again and can therefore easily be recycled.
- the DE 202 15 523 U1 refers to the technical requirements placed on such cables to the Bosch regulation VS 18296-NKA (October 2001) and, in addition to recyclability, refers in particular to the technical parameters of heat resistance and bending fatigue strength according to VDE 0472-603/J.
- Other properties, particularly mechanical ones, which are important for the use of lines of the type mentioned at the outset, include not only the mass of the line but also the torsional behavior. For the processability of the lines, the requirement that the line should be able to be stripped easily, possibly also over larger line sections, also plays a role.
- the jacket is made up of several layers of foamed and non-foamed materials, in particular of at least one non-foamed layer of PP.
- the prior art also refers to the fact that the cover layer should be designed as a non-foamed PP layer in order to improve the stripping behavior.
- a porous top layer made of a non-foamed PP has various other disadvantages in addition to the porosity and also an adhesive bond between the non-foamed material and a foamed intermediate layer.
- the present invention is therefore based on the object of creating an electrical cable of the type mentioned at the outset, which has improved quality with regard to the above-mentioned mechanical and processing properties and, in particular, can be produced easily and inexpensively and has high mechanical stability to the outside, without the flexibility of the line suffering.
- a specific line structure with materials is used for this purpose, which bring particular advantages in the proposed combination.
- a first idea is to do without the actual inner jacket around the insulation of the multiple lines of the electrical line arrangement and to attach a jacket made of a foamed material directly around the insulation in this way. Among other things, this saves a production step and the problem of the connection between layers of foamed and non-foamed materials can be avoided.
- thermoplastic polymers with a foamed as well as non-foamed insulation is possible, with which a good adhesive bond can be achieved, while the mechanical and other properties remain easily controllable.
- a foamed jacket material is selected from a group of plastics that are both thermoplastic and elastic plastics at the same time, as they combine the cost-effective processability of thermoplastics with the elastic properties of elastomers.
- Thermoplastic vulcanizates are suitable for this.
- thermoplastic polymer with a polypropylene matrix for this purpose.
- EPDM particles ie ethylene-propylene-diene rubber particles
- thermoplastics can also be used as foamed variants as insulation material for the cables.
- Adhesives, binders and physical or mechanical connections that previously had to be used for such composite parts can be saved as a result. Another advantage that turned out to be that the process reduces the number of process steps and can thus reduce the cycle time of component production and the overall system costs.
- the proposed elastomeric, foamed jacket material can be bonded particularly firmly to plastics such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS), acrylonitrile styrene acrylate (ASA), polymethyl methacrylate (PMMA) and polyethylene terephthalate (PET).
- PC polycarbonate
- ABS acrylonitrile butadiene styrene
- ASA acrylonitrile styrene acrylate
- PMMA polymethyl methacrylate
- PET polyethylene terephthalate
- an electrical line comprising a plurality of electrical conductors, each with insulation and a common jacket made of plastic, the common jacket being applied directly to and around the insulation of the conductors without an intermediate layer and the jacket being selected is from the group of plastics which are both thermoplastic and elastic plastics at the same time and preferably have a polypropylene matrix or polyethylene matrix and furthermore a thin hard cover layer made of a non-foamed material is formed around the jacket.
- the invention advantageously reduces the specific mass of the cable, stripping the sheathing over larger and oversized cable lengths is made easier, and the torsional behavior improves as well as the mechanical properties due to a damping effect of the foamed layer pressure resistance and flexural fatigue strength.
- the material of the hard top layer consists of a thermoplastic PUR.
- a concept is achieved whose properties include dynamic resilience, high flexibility in a wide temperature range, high wear resistance as well as buckling and tear resistance with good resistance to the influence of oil, grease and solvents, the weather, ozone and UV radiation , and combine hydrolytic substances. Furthermore, such lines can be easily subjected to recycling.
- the material of the insulation can also consist of a foamed plastic according to the concept of the invention.
- no intermediate layer is arranged between the hard top layer and the jacket and in particular also no intermediate layer with the function of promoting adhesion or producing the mechanical connection to the jacket.
- the jacket is attached coaxially and preferably with a round cross-sectional contour around the conductors. It is also advantageous if the thin cover layer 4 is attached coaxially and preferably with a round cross-sectional contour around the jacket.
- other shapes, in particular non-round shapes, are also conceivable and possible.
- a sheathed electrical line 10 from a plurality of electrical conductors 1, all of which are provided with insulation 2 each.
- four electrical conductors 1 are shown.
- a common sheath 3 is provided around these four conductors 1, namely around their insulation 2, which sheath bears against the outer contour of the insulation 2 without an intermediate layer.
- the common jacket 3 consists of a specific plastic, namely a thermoplastic vulcanizate. In the exemplary embodiment shown, this is designed as a thermoplastic polymer with a polypropylene matrix. EPDM particles are embedded in the polypropylene matrix, so that a thermoplastic vulcanizate with ethylene-propylene-diene rubber particles is provided.
- the insulation 2 is made of a soft non-foamed material.
- the insulation 2 of the conductor 1 can be made of polyurethane or a material used for such insulation, e.g. B. from a thermoplastic elastomer (TPE), in particular styrene-containing TPE, a polyolefin such as polypropylene (PP), an ethylene-vinyl acetate copolymer (EVA) or a fluoropolymer such as FEP (tetrafluoroethylene-hexafluoropropylene copolymer) exist.
- TPE thermoplastic elastomer
- PP polypropylene
- EVA ethylene-vinyl acetate copolymer
- FEP tetrafluoroethylene-hexafluoropropylene copolymer
- FEP tetrafluoroethylene-hexafluoropropylene copolymer
- a thin, hard cover layer 4 made of a non-foamed TPU is applied directly around the jacket 3 .
- the conductor 1 can consist of an electrically conductive material in the form of strands or in the form of a wire.
- a wire used for the conductor 1 can also be formed from a plurality of individual wires 1a, and thus be designed as a stranded conductor.
