Summary of the invention
The purpose of this utility model is to provide a kind of anti-interference digital signal transmission combination cable, adopts the mode of data cable and power cables combination, while transmission of data signals, can also provide power supply signal to equipment, and strong anti-interference performance.
The technical scheme that the utility model adopts 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.
The beneficial effects of the utility model are: 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 utility model;
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1,2 and embodiment, the utility model 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 the utility model pair twist group 10 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 utility model is not limited 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.
