It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Examples
In order to solve the above-mentioned technical problems, the present embodiment provides a variety of near field communication carrier interaction harnesses, as shown in fig. 1, including two twisted pair first core wires 10, a plurality of second core wires 20 and filler strips 30. The first core wire 10, the second core wire 20 and the filler 30 are sequentially coated with a wrapping tape 40 and an outer coating layer 50. Wherein, two first heart yearns 10 are stranded from S to, and the ratio of the strand pitch of two first heart yearns 10 to the wire diameter is 15-20, and then avoids the pair twist ripple jump point. The first core wire 10 comprises a plurality of conductors 11 and fiber wires 13 which are stranded, and an insulating layer 12 is coated on the peripheries of the conductors 11 and the fiber wires 13. The conductors 11 are stranded mutually, under the premise of ensuring softness of the wires, the conductors are stranded to achieve higher roundness, and the fiber 13 is added, so that bending performance of a single first core wire 10 can be improved, the first core wire has tensile resistance, the tensile strength requirement of the wires can be ensured, and stable signal transmission is ensured in near field communication.
Further, the conductors 11 are annealed copper wires, the wire diameter of the conductors 11 is 0.05-0.08mm, the number of the conductors 11 is 4-6, and the wire diameter of the first core wire 10 is 0.3-0.6mm. On the premise of ensuring the softness of the wire, the A-type conductor is adopted for twisting so that the wire is higher in roundness. The insulating layer 12 is made of PP and PVC materials, so that the temperature resistance level can reach-60-105 ℃, the physical properties of the materials are excellent, the thickness of the insulating layer 12 can be designed to be smaller, the wire diameter can be designed to be smaller, the appearance is smooth and is not easy to adhere, and the processing and the crimping are easy.
Further, the number of the second core wires 20 is four, after the first core wires 10, the plurality of second core wires 20 and the filler strips 30 are cabled, the second core wires are stranded towards the wrapping belt 40, so that the rounding and compaction of the wires are ensured, and the overall wire diameter of the wires is further reduced. Further, the filler strips 30 are polyester fiber yarns, and the wire diameter of the polyester fiber yarns 30 is 0.15-0.2 mm, so that the stability of the wire structure is ensured, and the wire is kept soft and the breaking force is enhanced.
The outer coating 50 is made of elastomer polyvinyl chloride and TPE materials, and has the advantages of high temperature resistance, low temperature resistance, oil stain resistance and chemical reagent resistance. The outer coating 50 is extruded by a half extrusion tube to ensure that the wire skin is not elongated when the outer coating is cut. Because the installation space is narrow in the car, traditional on-vehicle line need be removed when the installation and then install, and the bending point is fixed, and R angle is less when buckling and is very destructive to the heart yearn wire rod. For this reason, the thickness of the outer coating 50 in this embodiment is 0.2-0.3 mm, and after the first core wire 10, the plurality of second core wires 20 and the filler strips 30 are cabled, the wires are twisted to the tape S, so as to ensure the rounding and compaction of the wires, and further reduce the overall wire diameter of the wires. Further, the outer coating 50 is kept during installation, so that the bending point is located on the outer coating 50, the bending performance is improved, and the wire damage is reduced.

The peripheries of the first core wire, the second core wire and the filling strip are sequentially coated with a wrapping belt and an outer coating. The two first core wires are twisted from S direction, and the ratio of the twisting pitch of the two first core wires to the wire diameter is 15-20, so that the twisted corrugated jump point is avoided. The first core wire comprises a plurality of conductors and fiber wires stranded mutually, and an insulating layer is coated on the peripheries of the conductors and the fiber wires. The conductors are twisted mutually, the conductors are twisted to achieve higher roundness on the premise of ensuring softness of the wires, and the fiber wires can increase bending performance of a single first core wire, so that the first core wire has tensile resistance, the tensile strength requirement of the wires can be ensured, and stable signal transmission is ensured in near field communication.
