Abstract
The invention relates to a high shielding instrument cable for a communication device, which consists of a conductor, an insulating layer, an inner pad layer, an aluminum plastic compound strip shield, a shielding drainage wire, a braided shield and an outer jacket. The high shielding instrument cable is particularly characterized in that a plurality of 2*2*24 AWG tinned electrolytic copper wires are stranded to form the cable conductor; the surface of the conductor is coated with the insulating layer; the insulating material adopts the insulating material resisting the high temperature of +250 DEG C; the cable has the characteristics of high temperature resistance, acid and base resistance, corrosive gas resistance, water prevention and the like; the shielding material adopts a double shielding mode, namely 100 percent coverage of aluminum foil/polyester compound strip and 90 percent coverage of the tinned copper wires; and the high shielding instrument cable for the communication device is additionally provided with an independent earthing conductor.
Description
Technical field the invention belongs to the instrument cable field, a kind of specifically the signal transmission in instrument, instrument and other equipment and high shielding instrument cable for communication device of control circuit of relating to.
Technical background is present, needs a kind of a kind of cable that shield effectiveness, electric capacity are had relatively high expectations in the use field of instrument, instrument and other equipment.Traditional material can't satisfy the use needs of particular surroundings, therefore needs a kind of high shielding instrument cable for communication device of research and development.
Summary of the invention the present invention be provide in order to remedy above-mentioned deficiency point have characteristics such as heat-resisting radiation, acid and alkali-resistance and corrosive gas, waterproof, a high shielding instrument cable for communication device of advantages such as construction of cable softness.
Concrete technical scheme of the present invention is:
The present invention is made of conductor, insulating barrier, inner cushion layer, aluminium-plastic tape shielding, shielding drainage thread, braid shielded, oversheath.It specifically is characterised in that: the cable conductor conductor is that the zinc-plated cathode copper skein silk of 2*2*24AWG multiply closes and forms, coat a layer insulating at conductive surface, the insulating material of insulating material adopts high temperature resistant+250 degree have characteristics such as high temperature resistant, acid and alkali-resistance and corrosive gas, waterproof.Shielding material adopts aluminium foil/polyester composite band 100% covering+tinned copper wire 90% to cover two-fold shielding altogether, with independent grounding lead high shielding instrument cable for communication device.
When using high shielding instrument cable for communication device, for specific transmission line, main frame (calling measurement equipment together) is inversely proportional to the cable length between 485 mouthfuls of instrument and the baud rate of data; This length is influenced by the distortion of signal and The noise mainly.The transmission range of instrument cable can reach 1200 meters in theory, but transmission range is greater than 1200 meters in the practical application.
Project organization of the present invention is scientific and reasonable, has both improved the shield effectiveness of cable, can guarantee that again the flexibility of cable reaches requirement of client, and is almost nil to the damage type of cable, and has characteristics such as with low cost, handling safety, use be very convenient.
Description of drawings
Fig. 1 is a simplified schematic diagram of the present invention;
Embodiment is the communication equipment high capacitance as shown in Figure 1, shielding instrument cable, be by conductor 1, insulating barrier 2, inner cushion layer 3, aluminium-plastic tape shielding 4, shielding drainage thread 5, braid shielded 6, oversheath 7 is formed, it is characterized in that: conductor 1 forms for the zinc-plated cathode copper skein silk of 2*2*24AWG multiply closes, the pattern insulating sleeve is suitable for installs identification, overall 100% shielding of aluminium foil/polyester belt, additional independent strands tinned copper wire earthing conductor, industry grey PVC oversheath 7, the PE dielectric, cover two-fold shielding altogether by aluminium foil/polyester composite band 100% covering+tinned copper wire 90%, with independent grounding lead high shielding instrument cable for communication device.
Utilize good soft characteristics, the cable capacitance of thermoplastic elastomer (TPE) little, use aluminium plastic composite material as shielding, and the screening behavior of woven structure, enlarged the use occasion of instrument line, especially require jamproof occasion.
The above; preferable specific embodiments for the invention of this cable; but protection scope of the present invention is not limited thereto; all are familiar with those skilled in the art in technical scope disclosed by the invention; be equal to replacement or change according to technical scheme of the present invention and design of the present invention thereof, all should be encompassed within protection scope of the present invention.
