Abstract
A power radio frequency transmission combination cable includes a radio frequency cable (13) and a power line (14). Two power lines (14) are twisted to wrap a shielding layer I (10); a shielding layer II (9) is braided outside the shielding layer I (10); an inner sheath I (8) is extruded outside the shielding layer II (9), so that a power twisting group (15) is formed; the power twisting group (15) and the radio frequency cable (13) are twisted at a large pitch so as to form a spiral cable core which is used to wrap an aluminum base composite belt (2); and an outer sheath (1) is extruded outside the aluminum based composite belt (2). According to the utility model, the power line and the image transmission cable are combined together, so that the neat wiring, easy installation and little affect on the signal transmission are realized.
Description
Technical field
The utility model belongs to cable technology field, is specifically related to a kind of power supply radio frequency transmission combination cable.
Background technology
Microwave digital image transmission system transmitting terminal adopts feed cable and two groups of cables of signal cable to realize the transmission of Digital Microwave and image conventionally.But in wiring process, on the one hand can make circuit very in disorder, when through walls on the other hand, will pass from two holes, cause a lot of troubles to wiring punching and affect signal and transmit.
Summary of the invention
The technical problem that the utility model solves: design a kind of power supply radio frequency combining transmission cable, power line and image transmission cable are combined, not only wiring neatly, is easily installed but also is not affected signal transmission, the problem having existed while having solved existing microwave digital image transmission system transmitting terminal wiring.
Technical solution of the present utility model: a kind of power supply radio frequency transmission combination cable, comprise radio frequency cable and power line, coated screen I after two power line pair twists, the outer woven shield II of screen I, screen II extrudes inner sheath I outward, form power supply pair twist group, power supply pair twist group and radio frequency cable are stranding into wrapped aluminum-base composite band after spiral type cable core with coarse pitch, on aluminum-base composite band, extrude oversheath.
Described radio frequency cable by conductor wire core I, be coated on insulating barrier I in conductor wire core I, be coated on screen III outside insulating barrier I, be woven in the screen IV outside screen III and the inner sheath II that extrudes in screen IV forms.
Described power line is made up of conductor wire core II and the insulating barrier II extruding in conductor wire core II.
The advantage the utlity model has and effect:
1, the utility model always shielding again after shielding by grouping, reduces cross-talk, and stable signal transmission is accurate, and long-distance transmissions decay is little.
2, after two power line pair twists of the utility model, make power supply signal decay in transmission way little, guaranteed its characteristic impedance.
3, the utility model insulation and sheath material proportion are little, and the lightweight intensity of cable is good, and good looking appearance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model section structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
A kind of power supply radio frequency transmission combination cable, comprise radio frequency cable 13 and power line 14, coated screen I 10 after two power line 14 pair twists, the outer woven shield II 9 of screen I 10, the outer inner sheath I 8 that extrudes of screen II 9, form power supply pair twist group 15, power supply pair twist group 15 and radio frequency cable 13 are stranding into wrapped aluminum-base composite band 2 after spiral type cable core with coarse pitch, extrude oversheath 1 on aluminum-base composite band 2.
Described radio frequency cable 13 by conductor wire core I 7, be coated on insulating barrier I 6 in conductor wire core I 7, be coated on screen III 5 outside insulating barrier I 6, be woven in the screen IV 4 outside screen III 5 and the inner sheath II 3 that extrudes in screen IV 4 forms.
Described power line 14 is made up of conductor wire core II 12 and the insulating barrier II 11 extruding in conductor wire core II 12.
The core that the utility model is made up of single diameter 0.9mm circular copper wire, as conductor wire core I 7, is the main transmission channel of data-signal and analog signal.The aluminium-plastic tape that employing width is 12mm is with the overlapping wrapped one-tenth screen III 5 of 2-3mm, adopt the naked circular copper wire of 5 strand of 16 ingot to be woven into screen IV 4, form the screen of unlike material, shielding interference signal, then adopt pvc material to extrude inner sheath II 3 to form radio frequency cable 13.The core forming using 8+14+20 layer-strandings with 0.20mm circular copper wire is as conductor wire core II 12, the insulating barrier II 11 that extrudes 0.8mm with polytetrafluoroethylene forms power line 14, two power lines 14 are according to certain pair twist pitch pair twist, to reduce the decay of power supply signal transmission.After two power line 14 pair twists, be coated again the screen I 10 of plastic-aluminum composite, adopting 5 strands of diameters of 16 ingot is 0.15mm circular copper wire woven shield II 9 again, interference signal is shielded, and screen II 9 is outer extrudes that thickness is that 0.8mm environmental protection, fire-retardant, low temperature resistant, wear-resistant, radiation hardness, oil resistant are soaked, resistance to ozone, corrosion resistant polyurethane form power supply pair twist group 15 as inner sheath I 8.Radio frequency cable 13 adopts coarse pitch limit lining cotton yarn stranding with power supply pair twist group 15, form the one-tenth cable core of Stability Analysis of Structures rounding, and the outer wrapped aluminum-base composite band 2 of cable core is with shielding interference signal, and signal stabilization is accurately transmitted.It is 1.5mm that outermost layer extrudes a layer thickness, and environmental protection, fire-retardant, low temperature resistant, wear-resistant, radiation hardness, oil resistant soak, resistance to ozone, corrosion resistant polyurethane rubber-plastic protective cover 1 form desirable power supply radio frequency transmission combination cable.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, thus all equivalent variations of being done with content described in the utility model claim, within all should being included in the utility model claim scope.
