Technical field

The utility model relates to a kind of cable, specially a kind of agriculture equipment integrated communication cable.

Background technique

The needs of China's modern agricultural development are answered, modern farm needs a large amount of electrical equipment to realize intelligent management, prison Control and equipment operation, these equipment are proposed very high requirement to the data transmission of cable and power transmission, however existing High frequency communications cable suffer a disadvantage in that

1, generally use that optical fiber cable, to surpass six classes and seven kinds of data grid line logical as high frequency in existing communication data cable Interrogate cable, in these communication cables in addition to optical cable due to shielding material using metal wire knitted or metal tape wrapped, this screen Shield structure becomes the channel inside liquid intrusion cable there are crack, is not suitable for so as to cause these cables long in field environment Phase uses；

2, existing fiber optical cable is very high to installation requirement, especially joint area, and in the occasion of static state wiring, optical fiber is produced Product have the clear superiorities such as flow big, long service life, signal stabilization, however in the mobile equipment used, fiber products are answered The defects of deficiency, the connector slight misalignment that optical signal refraction requires bending radius limited bring dispersion aggravation signal decaying obvious is just As technical problem insoluble in practical application；

3, optical fiber can be caused to generate added losses under hydrogen ion effect after cable is invaded by water body, here it is optical fiber The hydrogen loss phenomenon most paid attention to is produced, therefore avoiding water body intrusion optical fiber is also the most important key element of optic cable design, although light Cable prevents water body from invading using a large amount of factice for filling, but the equipment in field environment once has water body when using optical fiber Intrusion will result in loss of signal and increase even shortening optical cable service life.
