Description
Technical field
This utility model relates to automobile cable field, is specifically related to a kind of polyurethane battery cable.
Background technology
Development along with auto industry, functional part and auxiliary device that in automobile, electric appliance and electronic is relevant are increasing, battery cable as tremulous pulse electric in car, its reliability directly affects the safety of vehicle and normal traveling, therefore along with the further development of auto industry, the requirement that the reliability of battery cable has been proposed higher.
Traditional battery cable adopts PVC(polrvinyl chloride mostly) insulation, but the mechanical strength of PVC insulated cable relatively low (12 ~ 20MPa), not only wear-resisting vibration resistance is poor, percentage elongation is little, poor flexibility, and the cable finished product produced is typically due to insulation thickness and causes greatly external diameter big, should not bend and lay inconvenience.Owing to inner space of vehicle bends than narrow and cable laying path very much, therefore the softness of cable has significantly high requirement.Polyurethane elastomer is had the advantages such as high mechanical strength, percentage elongation and resistance to ag(e)ing due to it, is widely used in cable industry.
Polyurethane elastomer insulated cable can significantly improve mechanical strength and the wearability of cable, and the size of product is little, good springiness, be easily installed and lay, but traditional solid insulation polyurethane elastomer cable is due to its mechanical strength superfluous (typically up to 30 ~ 50MPa), often result in difficulty of processing greatly even to be difficult to process so that it is be difficult to further genralrlization application.
Utility model content
In view of this, this utility model provides a kind of polyurethane battery cable, it is intended to while optimizing cable performance, reduces the difficulty of processing of cable.
The technical solution adopted in the utility model particularly as follows:
A kind of polyurethane battery cable, including core body and be coated on the composite insulation layer outside described core body；Wherein:
