Abstract
The utility model discloses an environmental protection data type high-precision instrument cable, comprising a sheath, one or more intertwisted wire sets arranged inside the sheath, wherein each intertwisted wire set comprises an intertwisted shielding layer and two insulating wire cores arranged inside an intertwisted shielding layer, and each insulating wire core comprises a conductor, an inner insulating layer wrapping the conductor, and an outer insulating layer wrapping the inner insulating layer. The environmental protection data type high-precision instrument cable is scientific and reasonable in design, easy in production and manufacture, low in cost and good in cable application performance. Due to the design of the shielding layer and the material of the outer sheath, the environmental protection data type high-precision instrument cable has the characteristics of being low in capacitance, transmission attenuation and insulating medium loss, and high in signal transmission performance, precision and stability; the environmental protection data type high-precision instrument cable has a good shielding effect, thereby not only protecting the cable from being interfered by extraneous interference, but also preventing the cable interfering other electronic devices; and the cable is long in service life, is green and environment-friendly and pollution-free, and can satisfy the performance demands of the cable for the modern instruments and meters.
Description
Technical field
The utility model relates to a kind of environment protection digital type high-precise meter cable.
Background technology
China's instrument industry technology is relatively backward, and its supporting cable performance does not reach specification requirement and the instructions for use of instrument and meter.Under this instrument and meter development trend, its supporting cable is had higher requirement accordingly, as the stability, low-loss, high reliability, the anti-interference that require cable signal to transmit, the multifunctionality of using etc., and the existing traditional meters cable that sets gradually insulating barrier, screen and sheath etc. on conductor has been difficult to reach and has simultaneously above function.At present domestic demand to this type of cable is leaned on import basically.
The utility model content
Main purpose of the present utility model is to provide a kind of high-transmission stability, low-loss, high sensitivity, high resistance electromagnetic interference, low electric capacity, long environment protection digital type high-precise meter cable of life-span.
For addressing the above problem, the utility model adopts following technical scheme: a kind of environment protection digital type high-precise meter cable, comprise sheath, and be arranged in sheath, the twisted pair wire group more than, described twisted pair wire group comprises the pair twist screen, and is arranged on two eradication edge cores in the pair twist screen; Described insulated wire cores comprises conductor, and is coated on the inner insulating layer on conductor, and is coated on the external insulation layer on inner insulating layer.
Further, also be provided with foamed insulation between described inner insulating layer and external insulation layer.
Further, be provided with waterstop between described twisted pair wire group and sheath.
The beneficial effect of the utility model environment protection digital type high-precise meter cable is: design science is reasonable, manufactures easily, and cost is low, and the cable serviceability is good.Screen design and jacket material the measure such as select, make cable have low electric capacity, low transmission decays; The low insulation dielectric loss; High-performance, high accuracy, the high stability of signal transmission; Good shield effectiveness both can prevent the interference of outer bound pair cable, can prevent that also cable is to the interference of other electronic apparatus system; Long service life, environmental protection, pollution-free.Satisfy modern instrument instrument cable performance requirement.
Description of drawings
Fig. 1 is the schematic diagram of the utility model environment protection digital type high-precise meter cable.
Embodiment
See also shown in Figure 1, a kind of environment protection digital type high-precise meter cable of the present utility model comprises sheath 1, and be arranged in sheath 1, the twisted pair wire group 2 more than, described twisted pair wire group 2 comprises pair twist screen 20, and is arranged on two eradication edge cores 21 in pair twist screen 20; Described insulated wire cores 21 comprises conductor 22, and is coated on the inner insulating layer 23 on conductor 22, and is coated on the external insulation layer 24 on inner insulating layer 23.
Also be provided with foamed insulation 25 between described inner insulating layer 23 and external insulation layer 24.Be provided with waterstop 3 between described twisted pair wire group 2 and sheath 1.
The beneficial effect of the utility model environment protection digital type high-precise meter cable is: design science is reasonable, manufactures easily, and cost is low, and the cable serviceability is good.Screen design and jacket material the measure such as select, make cable have low electric capacity, low transmission decays; The low insulation dielectric loss; High-performance, high accuracy, the high stability of signal transmission; Good shield effectiveness both can prevent the interference of outer bound pair cable, can prevent that also cable is to the interference of other electronic apparatus system; Long service life, environmental protection, pollution-free.Satisfy modern instrument instrument cable performance requirement.
The above be only embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
