Problems solved by technology

Traditional sensor cables generally use XLPE (cross-linked polyethylene) as the cable sheath and insulation layer. XLPE cables have excellent electrical properties. Although they can meet the transmission requirements, they still have the following defects: First, they have poor temperature resistance. The temperature grade ranges from -10 to 150°C, and the applicable environment is limited; second, the oil resistance is poor, and the sensor cable will be in contact with the gearbox oil during use. Over time, the cable will crack and seriously affect the service life; Poor bending resistance, hard cables, the minimum bending radius is eight times the outer diameter of the cable, unable to meet the 500,000 times bending test, and the service life is short

Abstract

A fluororubber cable for sensors belongs to the technical field of vehicle electric wires and cables. The fluororubber cable for sensors comprises multiple wire cores, and a taped covering and a sheath sequentially arranged outside the wire cores, wherein every wire core is composed of a conductor and an insulation layer. The fluororubber cable for sensors is characterized in that the insulation layer is made of polyperfluorinated ethylene propylene and is extruded outside the conductor, and the sheath is made of fluororubber and is extruded outside the taped covering. The fluororubber cable for sensors is excellent in oil resistance, corrosion resistance, temperature resistance and bending resistance, has good cable flexibility, long service life and wide application scope, and can be used in a harsh environment.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables for vehicles, and in particular relates to a fluorine rubber cable for a sensor, which is used for connecting an automobile engine to a sensor on a gearbox. Background technique [0002] One of the characteristics of the development of automobile technology is that more and more components are controlled electronically. Automotive sensors are input devices for automotive computer systems, and are mainly used in gearboxes, steering gears, and ABS systems. As cables used to connect sensors on automobile engines and gearboxes, not only good physical properties such as bending resistance are required, but also excellent chemical corrosion resistance such as heat resistance, oil resistance and radiation resistance are required. Traditional sensor cables generally use XLPE (cross-linked polyethylene) as the cable sheath and insulation layer. XLPE cables have excellent electrical prope...
