Abstract
The utility model discloses an automobile reversing vision cable is morally marked to high performance, including the cable core, its cable core is formed by a data transmission cable and two power cord transposition that parallel from top to bottom, be equipped with outside and tegillum of first shielding layer that tegillum among the electrically conductive PVC, aluminium foil or copper wove, tin coating in proper order outside the cable core, wherein, the data transmission cable include by two data transmission lines and the cable core that the ground wire constitutes of pair twist side by side about being that the cable core directly is equipped with the secondary shielding layer that aluminium foil or copper were woven outward. The utility model discloses increased the conveying length of twisted pair wire, accomplished 100% shielding effect on the shielding layer, improved biography insemination degree, the quality of cable, in the deep -processing and using, because of the tin composition is the soft metal, be fit for using and the deep -processing simultaneously.
Description
Technical field
This utility model relates to electric wire field, is specifically related to a kind of high-performance moral mark reversing automobile vision cable.
Background technology
Prior art is applied, current reversing automobile vision cable, all uses following two structure transmission, and the first is that single core coaxial cable adds two power lines, and shielding uses braiding structure, and outermost layer is outer quilt；The second is that a pair twisted component wires adds two power lines, and shielding uses braiding structure, and outermost layer is outer quilt.
Both the above cable all has different defect, the first product structure is owing to using coaxial configuration, coaxial line transmission means analogue signal, although such signal transmitting range is long, but resolution is low, cannot meet the resolution of current superior automobile GPS, this series products highest resolution is 1280 × 720, so the first design is quickly withdrawn from the market at present.The second product structure uses differential digital transmission means, which resolution can reach 1080P, reaches as high as 4K at present, but owing to such design transmission range is shorter, 10 meters can be reached under disturbing without external magnetic field, more than 10 meters slowed-down videos increase, and reversing automobile vision cable uses length 8 ~ 10 meters, in the magnetic interference by automobile, use braid shielded ground connection, this shield effectiveness can only reach shielding 90%, and shielding cannot accomplish 100% shielding always, therefore the most restricted in transmission range.
Utility model content
In order to overcome the deficiencies in the prior art, it is provided that a kind of transmission length adding twisted pair wire, accomplish the high-performance moral mark reversing automobile vision cable of 100% shield effectiveness on the shielding layer.
For achieving the above object, this utility model provides a kind of high-performance moral mark reversing automobile vision cable, and including cable core, its cable core is formed by a data transmission cable and about two power lines arranged side by side are stranded；Tegillum in conduction PVC, aluminium foil or the first screen layer, tin coating and the serving of copper braiding it is sequentially provided with outside cable core；Wherein, described data transmission cable includes the cable core being made up of two single data transmission lines and the ground wire in pair twist arranged side by side up and down, is directly provided with aluminium foil or the secondary shielding layer of copper braiding outside cable core.
Preferably, described data line is made up of transmission conductor and the polyethylene foamed insulating barrier that is extruded in outside transmission conductor.
Preferably, described power line is made up of power conductor and the polyethylene layer that is extruded in outside power conductor.
The beneficial effects of the utility model are:
This utility model two core pair twist data line, uses polyethylene foamed insulation system, after polyethylene foam, the dielectric constant of polyethylene is diminished, increases data and transmit wavelength rate, reduce the electric capacity of twisted pair wire, thus reduce data transmitting attenuation, increase cable and transmit length；In pair twist data core peripheral hardware ground wire and aluminum foil shielded structure, reduce two power lines and data are transmitted interference；Middle tegillum not only increases shield effectiveness, the roundness of cable is increased as interstitital texture, also making place mat for tin coating, the aperture that woven shield cannot fill up is filled up by tin coating, and screen layer is made sealing pipe assembling structure, fully wrapped around cable internal structure, thus accomplish 100% shield effectiveness, improve the transmission precision of cable, quality, simultaneously in deep processing and using, because stannum composition is soft metal, it is suitable for using and deep processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As it is shown in figure 1, this utility model provides a kind of high-performance moral mark reversing automobile vision cable, including cable core, its cable core is formed by a data transmission cable and about two power lines arranged side by side are stranded；Wherein, described data transmission cable includes the cable core being made up of two single data transmission lines and the ground wire 3 in pair twist arranged side by side up and down, is directly provided with aluminium foil or the secondary shielding layer 4 of copper braiding outside cable core；
Described data line is made up of transmission conductor 1 and the polyethylene foamed insulating barrier 2 that is extruded in outside transmission conductor 1, use polyethylene foamed insulation system, after polyethylene foam, the dielectric constant of polyethylene is diminished, increase data and transmit wavelength rate, reduce the electric capacity of twisted pair wire, thus reduce data transmitting attenuation, increase cable and transmit length；
Described power line is made up of power conductor 5 and the polyethylene layer 6 that is extruded in outside power conductor；
Finally, tegillum 7 in conduction PVC, aluminium foil or the first screen layer 8, tin coating 9 and the serving 10 of copper braiding it is sequentially provided with outside cable core, middle tegillum not only increases shield effectiveness, as interstitital texture, also make place mat for tin coating, the aperture that woven shield cannot fill up is filled up by tin coating, screen layer is made sealing pipe assembling structure, fully wrapped around cable internal structure, thus accomplish 100% shield effectiveness, improve the transmission precision of cable, quality, simultaneously in deep processing and using, because stannum composition is soft metal, it is suitable for using and deep processing.
The above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of without departing from this utility model principle; can also make some modification and improvement, these also should be regarded as belonging to protection domain of the present utility model.
