Description
Technical field
The utility model relates to communication and electric power transfer field, but the particularly high frequency twisted pair conductors cable of transmitting high-frequency signal.
Background technology
In the communications field, on the power line of being everlasting, add the high-frequency carrier signal, be used for transmit communications signals, the number of it is believed that in full, clock signal, repeating signal, control signal or the like.Because the heart yearn of existing power cable is generally run-in index (two cores) and layer-twisted type (more than two cores), the distributed capacitance that forms between the insulating material of electric power cable and heart yearn absorbs very big to high-frequency signal.Simultaneously, signal cross-talk and environmental interference are also very big to the high-frequency signal transmission influence between heart yearn, cause common electric power cable to be not suitable for transmitting high-frequency signal, have influenced the effective utilization of electric power cable.As at present on power line the bandwidth of transmit communications signals narrower, only can reach 14Mpbs, can not satisfy the transmission demand of high speed networks such as local area network (LAN) far away.And in fact,,, improving the high-frequency insulation characteristic if can eliminate distributed capacitance and crosstalk because power line cable footpath is thicker, electric power cable can satisfy the transmission demand of high-frequency signal fully.Transmitting high-frequency signal in the electric power cable electric energy transmitting can effectively improve the effective utilization of electric power cable, reduces the usage quantity of network cable and lays work, and the utilization benefit that improves electric power cable is had very important significance.
Summary of the invention
The technical problems to be solved in the utility model is, at the narrow defective of existing power cable transmission frequency band, but proposes a kind of high frequency twisted pair conductors cable of transmitting high-frequency signal.
Implementation of the present utility model is: by the frame mode of communication twisted-pair feeder, structure high frequency twisted pair conductors cable makes its high-frequency transmission characteristic conforms communications cable requirement, and power transmission characteristics meets the electric power cable requirement.
High frequency twisted pair conductors cable, comprise that 1 or several heart yearns are right, every heart yearn comprises metallic conductor and the insulating case that is coated on the metallic conductor outside, it is characterized in that: described metallic conductor is sub-thread or multiply, per share diameter is not less than 0.3 millimeter, insulating case is the insulating material that meets requirement of communications cable insulating material and the requirement of electric power cable insulating material, heart yearn to by heart yearn by communication twisted-pair feeder stranded the forming of the stranded mode of heart yearn.
When heart yearn is that the metallic conductor of 1 pair and heart yearn is when being sub-thread or multiply bare wire, the core insulation cover is for meeting the insulating material of requirement of communications cable insulating material and the requirement of electric power cable insulating material, and heart yearn twisted together by communication multiple twin cabling mode, but form both transferring electric powers, high frequency twisted pair conductors that again can collinear transmitting high-frequency signal.For improving the performance of high frequency twisted pair conductors, outside the high frequency twisted pair conductors, add oversheath, just formed high frequency twisted pair conductors cable.Add that outside the high frequency twisted pair conductors metal screen layer and oversheath have just formed high frequency multiple twin shielding wire cable.
When heart yearn be several to and the metallic conductor of heart yearn when being sub-thread or multiply bare wire, the core insulation cover is for meeting the insulating material of requirement of communications cable insulating material and the requirement of electric power cable insulating material, and heart yearn twisted together by communication multiple twin cabling mode, simultaneously heart yearn is twisted together the heart yearn strand mode by the communication twisted-pair cable, formation can be transmitted the high frequency twisted pair conductors cable of multichannel civil power.For improving the performance of high frequency twisted pair conductors cable, also can outside every pair of heart yearn, add metal screen layer, or outside high frequency twisted pair conductors cable, add metal screen layer and oversheath, just formed high frequency multiple twin shielding wire cable.
Because it is less, on the high side to meet the insulating material kind of requirement of communications cable insulating material and the requirement of electric power cable insulating material simultaneously, make in order to reduce cost, to be convenient to, can adopt double hyer insulation cover mode, adopt the insulating material that meets the requirement of communications cable insulating material as internal layer, the outer insulating material that meets the requirement of electric power cable insulating material that adopts.
Another kind of high frequency twisted pair conductors cable, comprise 1 or several heart yearns, every heart yearn comprises metallic conductor and the insulating case that is coated on the metallic conductor outside, metallic conductor is made up of some twisted-pair feeders, it is characterized in that: described twisted-pair feeder is stranded by communication multiple twin cabling mode, twisted-pair feeder is to stranded by the right stranded mode of communication twisted-pair cable heart yearn, the insulating case of twisted-pair feeder is to meet the insulating material that communications cable insulating material requires, the conductor diameter of twisted-pair feeder is not less than 0.8 millimeter, and the insulating case of heart yearn is to meet the insulating material that the electric power cable insulating material requires.
Press the high frequency twisted pair conductors cable of said structure structure, a heart yearn can transmit the multichannel high-frequency signal simultaneously.In use, with the different high-frequency signal of different twisted-pair feeders transmission of root heart yearn, but all twisted-pair feeders and connect and form a power line.
In order to improve the high-frequency transmission performance, reduce external disturbance, can be at heart yearn added metal screen, or outside high frequency twisted pair conductors cable, add metal screen layer and oversheath, just formed high frequency multiple twin shielding wire cable.
In order to guarantee that electric power signal and signal of communication transmit simultaneously, are independent of each other, also to carry out Signal Separation and coupling in actual use at the communication equipment Transmitting and Receiving End, existing at present ripe method and technology do not repeat them here.
Benefit of the present utility model is, under the prerequisite of not obvious increase cost, utilizes stranded, the measures such as stranded and shielding that heart yearn is right of heart yearn, reduces the distributed capacitance between heart yearn and crosstalks; Adopt the insulating material that meets communications cable characteristic and electric power cable characteristic between heart yearn, both reduced the absorption of insulating material to high-frequency signal, improve the high-frequency transmission characteristic, the electric power cable characteristic that has also kept heart yearn, make high frequency twisted pair conductors cable in transferring electric power, can collinear carry high frequency signal of communication, effectively improve the electric power cable effective utilization, can be widely used in local communication networks such as family, school, Office Area, reduce cable consumption and wiring cost.
