Abstract
The utility model provides a low-voltage thin-wall cable used for a hybrid electric vehicle and belongs to the field of cables and wires. The low-voltage thin-wall cable used for the hybrid electric vehicle includes a conductor and an insulating sheath layer wrapping the conductor. The insulating sheath layer wraps the conductor in a firmly pressing manner. The conductor is formed through compound stranding of class-four or class-five conductors. According to the utility model, the safety performance and the environmental protection property of the low-voltage thin-wall cable used for the hybrid electric vehicle are improved, using requirements for comparatively high performance are satisfied, environmental aging is prevented and the service lifetime of the environmental aging is prolonged. The insulating sheath layer is made of high-elasticity composite polyester elastomer novel high polymer material, so that the using temperature range of the low-voltage thin-wall cable used for the hybrid electric vehicle is -60 DEG C to +125 DEG C, and the tensile strength of mechanical physical performance is larger than 30MPa and the elongation at break is larger than 400 percents. Since the material is halogen-free, the PH value is slightly larger than 7, the electric conductivity is smaller than 3 microsecond/mm and the toxicity index is smaller than 3. The low-voltage thin-wall cable used for the hybrid electric vehicle is ozone-aging-resisting and does not change practically in 72 hours in an environment with ozone concentration of 0.025 percent to 0.030 percent (by volume).
Description
Technical field
The utility model relates to the cable technology field, especially relates to a kind of Hybrid Vehicle low pressure thin-walled cable.
Background technology
The automobile cable of domestic production mostly is: the one, and common polyvinyl chloride insulation low-voltage cable, model is QVR, serviceability temperature-40 ℃～+ 80 ℃; The 2nd, heat-resistant polyvinyl chloride insulation low-voltage cable, model is QVR-105, serviceability temperature-40 ℃～+ 105 ℃ and polyvinyl chloride-butyronitrile compound low-voltage cable that insulate, model is QFR, serviceability temperature-40 ℃～+ 70 ℃.Ubiquitous problem: the one, temperature resistant grade is low, can not satisfy demand for development and the high-grade automobile requirement of new automobile, the power cable that the oil and electricity hybrid vehicle of at present domestic motor corporation's developments uses, serviceability temperature lowest range :-40 ℃～+ 125 ℃; And along with the development of automobile industry, the high request of serviceability temperature scope-40 ℃～+ 250 ℃ has been proposed; The 2nd, polyvinyl chloride cable insulating material toxicity index can not satisfy the environmental protection standard requirement up to 15.1.
Summary of the invention
The utility model mainly provides a kind of anti-flexibility, resistance to wear, and the oil resistant dirt, the high-low temperature resistant environment improves its electrical safety performance, and has a kind of Hybrid Vehicle low pressure thin-walled cable of good environmental protection characteristic and long service life.
For achieving the above object, the technical scheme that this utility model adopts is: a kind of Hybrid Vehicle low pressure thin-walled cable is characterized in comprising conductor and is coated on the outer insulating sleeve layer of conductor; Described insulating sleeve layer press packed bale overlays on the conductor, and described conductor adopts the 5th class or the 6th class conductor to twist again and forms.
The direction of twisting again described in the utility model adopts stranded in the same way.
Multiple strand described in the utility model adopts the 1+6+12+18 regular structure.
The pitch of twisting again described in the utility model adds " 2 " than inside every layer of " adding 2 rules " outermost layer, and namely 10,12,14.
Insulating properties sheath material described in the utility model is high resiliency complex polyester elastomer novel high polymer material, and its thickness is 0.35mm.
The effect that adopts above-mentioned engineering department to reach is: improved product fail safe, the feature of environmental protection, satisfy the instructions for use of superior performance, anti-environmental aging prolongs cable useful life; High resiliency complex polyester elastomer novel high polymer material is adopted in insulation, thereby cable serviceability temperature scope reaches-60 ℃～+ 125 ℃, in the mechanical and physical performance hot strength greater than 30MPa, elongation at break greater than 400%, material is that the Halogen pH value is slightly larger than 7, conductance is less than 3 μ s/mm, and poison exponent is lower than 3; Anti-ozone aging: ozone concentration is at 0.025% ~ 0.030% (by volume), and 72h is almost unchanged.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with structural scheme of mechanism this utility model is further elaborated: conductor (1) adopts the 5th class or the 6th class conductor, adopt 1+6+12+18 regular structure and pitch " to add 2 rules " with lay ratio, inside every layer of outermost layer adds " 2 " i.e. 10,12,14 mode multiple stranded forming in the same way, and the insulating barrier sheath (2) that then will adopt high resiliency complex polyester elastomer novel high polymer material to make presses on the coating conductor (1).
