Abstract
The invention discloses an anti-interference combination cable for transmitting a digital signal. A data cable and a power cable are cabled by lining two tearing ropes at a coarse pitch to form a cable core of the combination cable, the cable core is coated with a total shielding layer formed by knitting a tinned round copper wire, and a low-temperature-resistant elastomer sheath is arranged outside the total shielding layer in an extruding manner; the data cable is cabled by a pair stranding group in a concentric layer stranding way to form a cable core, and the cable core is wrapped with two threads of aramid fiber yarn I and then is coated with a first shielding layer knitted from the tinned round copper wire; the pair stranding group is formed by stranding two data wires in pairs and is wrapped with an aluminum plastic belt shielding layer; the power cable is cabled by stranding four power wires in pairs to form a cable core, and the cable core is wrapped with two threads of aramid fiber yarn II and then is coated with a second shielding layer knitted from the tinned round copper wire. By adopting a combination mode of the data cable and the power cable, the data signal is transmitted, and meanwhile, a power signal can be provided for equipment; moreover, the anti-interference performance is strong.
Description
Technical field
The invention belongs to transmission cable technical field, be specifically related to a kind of anti-interference digital signal transmission combination cable.
Background technology
Existing digital signal transmission cable interference free performance is poor, along with the development that electron trade is maked rapid progress, interference signal source also becomes increasingly complex, data communication is subject to the interference of various electromagnetic signal, the digital signal transmission cable requiring it supporting can bear various adverse circumstances, and anti-electromagnetic field interference performance is strong, ensure that digital data transmission is accurately stable.And while digital data transmission, needs are given and device power supply (DPS) signal, and visible existing digital signal transmission cable is difficult to meet the demands.
Summary of the invention
The object of this invention is to provide a kind of anti-interference digital signal transmission combination cable, adopt the mode of data cable and power cables combination, while transmission of data signals, power supply signal can also be provided to equipment, and strong anti-interference performance.
The technical solution adopted in the present invention is: a kind of anti-interference digital signal transmission combination cable, described combination cable is served as a contrast two with coarse pitch limit and is torn rope stranding by a single data cable, power cables and formed cable core, and total screen of cable core outer cladding tin-plating round copper wire braiding, extrude low temperature resistant elastic body jacket outside total screen; Described data cable is formed cable core by pair twist group with concentric lay formula stranding, and the first screen of coated tin-plating round copper wire braiding after the outer wrapped two strands of aramid fiber yarns I of cable core; Described pair twist group is formed by two data lines pair twists, and the outer wrapped aluminum plastic belt screen of pair twist group; Described power cables forms cable core by four power line pair twist strandings, and the secondary shielding layer of coated tin-plating round copper wire braiding after the outer wrapped two strands of aramid fiber yarns II of cable core.
The conductor wire core I that described data wire is closed by tin-plating round copper wire bundle and the polyethylene layer extruded outside conductor wire core I are formed.
The conductor wire core II that described power line is closed by tin-plating round copper wire bundle and the teflon insulation layer extruded outside conductor wire core II are formed.
Beneficial effect of the present invention is: one is transmission of data signals while, can also provide power supply signal to equipment, and cable weight is light, and sheath material low temperature tolerance ability is strong, and cable strength is good, and adaptive capacity to environment is strong.Two is be provided with aluminum plastic belt screen and circular copper wire screen outside data signal line, by the mode that electric field shielding ripple and armoured magnetic field ripple combine, reach good effectiveness, in addition the third time shielding of total screen and the shielding of power line, make data line, power line interlocks at circuit, there is excellent interference free performance under interference signal complex environment, signal attenuation is little, and Signal transmissions is accurately reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is cross-sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1,2 and embodiment, the present invention is described in detail.
A kind of anti-interference digital signal transmission combination cable, serve as a contrast two by a single data cable 12, power cables 15 with coarse pitch limit to tear rope 13 stranding and formed cable core, and total screen 2 of cable core outer cladding tin-plating round copper wire braiding, extrude low temperature resistant elastic body jacket 1 outside total screen 2; Described data cable 12 is formed cable core by 4 pair twist groups 10 with concentric lay formula stranding, and the first screen 3 of coated tin-plating round copper wire braiding after the outer wrapped two strands of aramid fiber yarns I 11 of coarse pitch of cable core; Described pair twist group 10 is formed by two data lines 8 pair twists, and the outer wrapped aluminum plastic belt screen 7 of pair twist group 10; Described power cables 15 forms cable core by four power line 5 pair twist strandings, and the secondary shielding layer 4 of coated tin-plating round copper wire braiding after the outer wrapped two strands of aramid fiber yarns II 14 of coarse pitch of cable core.
Described data wire 8 by 7 and the conductor wire core I 9 that closes of the tin-plating round copper wire bundle that diameter is 0.16mm and the polyethylene layer that extrudes outside conductor wire core I 9 form.Described power line 5 by 19 and the conductor wire core II 6 that closes of the tin-plating round copper wire bundle that diameter is 0.16mm and the teflon insulation layer that extrudes outside conductor wire core II 6 form.
The outer wrapped aluminum plastic belt of pair twist group 10 of the present invention carries out electromagnetic shielding, and in cabling process, the outer wrapped two strands of 220DT aramid fiber yarns of cable core are not loose to ensure into cable core rounding, and its characteristic impedance is stablized and remains in the numerical value of regulation, damped impedance is stablized.The outer tin-plating round copper wire 8 strands by 0.10mm of described one-tenth cable core adopts 16 ingot braiding machines to weave the first screen 3, in order to shield the interference of interference source to digital signal, ensure that data cable transfer of data decay (ATTUNATION), near-end crosstalk attenuation (NEXT) reduce, return loss (RL) reduces, various types of signal transmission is good.Four power lines 5 form cable core according to certain pair twist pitch stranding, and the outer wrapped two strands of 220DT aramid fiber yarns of cable core are not loose to ensure into cable core rounding in cabling process, the outer tin-plating round copper wire 6 strands by 0.10mm of cable core adopts 16 ingot braiding machines to weave secondary shielding layer 4, in order to shield the interference of interference source to power supply signal.The tin-plating round copper wire 8 strands that total screen 2 is 0.12mm by diameter adopts 24 ingot braiding machines to weave and forms, and again shields the interference that interference source transmits digital signal and power supply signal.The low temperature elasticity body sheath 1 of low temperature resistant excellent effect still can ensure the intact use of cable at-40 DEG C.
The invention is not restricted to above-described embodiment, can increase or reduce the radical of holding wire and the radical of power line as required, and external diameter, holding wire color, power line color, conductor wire core diameter etc. all can change as required.
