Abstract
The utility model discloses a data bus cable for a vehicle and belongs to the technical fields of wires and cables. The data bus cable comprises a cable core and an outer jacket positioned outside the cable core. The data bus cable is characterized by further comprising a thin film layer and a shielding layer, wherein the thin film layer is positioned outside the cable core; the shielding layer is positioned between the thin film layer and the outer jacket; in addition, the shielding layer is a metal shielding layer formed by knitting tin-plated metal wires; and the outer jacket is made of low smoke zero halogen cross-linked polyolefin. With the technical scheme, by arranging the shielding layer between the cable core and the outer jacket, the data bus cable has excellent anti-jamming capability; and the outer jacket is made of low smoke zero halogen cross-linked polyolefin, thus the data bus cable has a perfect flame-retardant effect to embody the safety.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of vehicle data bus cable.
Background technology
Along with developing rapidly and extensive use on vehicle of electronic technology, the automotive electronics degree is improved day by day, after particularly the microelectronics device enters field of automobile control, brought epoch-making variation to development of automobile, be embodied in: functional, the operational stability of vehicle (automobile), fail safe, fuel economy and the feature of environmental protection have all obtained significantly promoting.In recent years, along with the fast development that vehicle mounted multimedia and office equipment are used on vehicle, the consumption of data bus cable constantly increases.Abroad, especially European, the means that vehicle is networked as electronic controller at benz, BMW and Volvo etc. with data bus cable.China Department of Science and Technology proposes: new-energy automobile developing goal to 2012 year, domestic have a new-energy automobile of 10% nearly.In addition, reach 1,000,000 to the hybrid vehicle sales volume of the U.S. in 2015, therefore, the used in new energy vehicles data bus cable has vast market prospect and bigger actual demand.
Undoubtedly, as the vehicle data bus cable, to anti-interference as electromagnetic interference with fire-retardant extremely harsh requirement arranged, yet, in disclosed patent and non-patent literature, there is no all have be fit to be applied to technology enlightenment vehicle and data bus cable that have excellent anti-interference and flame retardant effect, the applicant has carried out good try for this reason, and technical scheme described below produces under this background.
Summary of the invention
Task of the present utility model is that a kind of vehicle data bus cable that had not only had excellent antijamming capability but also had desirable flame retardant effect will be provided.
Task of the present utility model is finished like this, a kind of vehicle data bus cable, comprise cable core and be positioned at the outer oversheath of cable core, be characterised in that and also include thin layer and screen, thin layer is positioned at outside the cable core, and screen is between thin layer and oversheath, and, the metal screen layer of described screen for constituting by the braiding of tin metal silk, and described oversheath is the low smoke and zero halogen cross-linked polyolefin.
In a specific embodiment of the present utility model, described cable core comprises at least one pair of lead and a ground wire.
In another specific embodiment of the present utility model, described cable core also includes packing.
In another specific embodiment of the present utility model, described thin layer is the single face aluminium-foil paper that a side surface is compounded with aluminium foil, and the side with aluminium foil is towards described cable core.
In another specific embodiment of the present utility model, described low smoke and zero halogen cross-linked polyolefin is anti-125 ℃ low-smoke non-halogen flame-retardant cross-linked polyolefin.
The technical scheme that the utility model provides is owing to be provided with screen between cable core and oversheath, thereby has excellent antijamming capability (transfger impedance≤225 Ω/km＜1MHz 〉); Because oversheath 2 has been adopted the low-smoke non-halogen flame-retardant cross-linked polyolefin, thereby have desirable flame retardant effect and embody fail safe.
Description of drawings
Fig. 1 is a specific embodiment schematic diagram of the present utility model.
Embodiment
Ask for an interview Fig. 1, provided the cable core 1 that constitutes vehicle usefulness data bus cable of the present utility model, this cable core 1 comprises couple of conductor 11, and each lead 11 comprises conductor 111 and overlayed on conductor 111 insulation-coated layer 112 outward.Cable core 1 also comprises a ground wire 12, and in order to make cable core 1 have the rounding effect, in the present embodiment, cable core 1 and then include a pair of but be not limited to illustrated a pair of packing 13, packing 13 is solid packing, it can be filled the post of by the mineral wool rope that is not limited to.Coat the thin layer 3 that single face is compounded with aluminium foil outside cable core 1, aforesaid ground wire contacts with aluminium foil.The screen 4 that is formed by zinc-plated monofilament (being the tin metal silk) braiding is set outside thin layer 3, plays the effect of anti-electromagnetic interference by this screen 4, the surperficial transfger impedance of metal screen layer 4 is preferably designed for :≤225 Ω/km (1MHz).It is the oversheath 2 that anti-125 ℃ low-smoke non-halogen flame-retardant cross-linked polyolefin forms that the extruder that adopts wires and cables industry widely to use outside screen 4 squeezes the cover material material.
The resulting vehicle of the utility model the foregoing description is tested under secrecy provision through the applicant with data bus cable, and the result shows to have very good antijamming capability and technique effects such as high temperature resistant, fire-retardant and environmental protection.
