Description
Technical field
The present invention relates to cable technique, more particularly to a kind of twisted-pair cable and preparation method thereof.
Background technology
Twisted-pair feeder (twisted pair, TP) is most common transmission medium in a kind of generic cabling engineering, is by two
Copper conductor composition with insulating protective layer.The copper conductor that edge is thoroughly done away with two is twisted mutually together by certain density, Mei Yigen
The electric wave that the electric wave that conducting wire radiates in the transmission can be sent out on another single line is offset, and the journey of signal interference is effectively reduced
Degree.
Twisted-pair feeder is generally mutually entwined by two 22~No. 26 insulated copper wires, thus the name of " twisted-pair feeder " is also
?.In actual use, twisted-pair feeder is wrapped together in an insulated cable casing by multipair twisted-pair feeder.If a pair of or
Multipair twisted-pair feeder, which is placed in an insulating sleeve, has become twisted-pair cable, but generally that " twisted-pair cable " is straight in daily life
It connects referred to as " twisted-pair feeder ".
In the prior art, there are multipair twisted-pair feeder, the direction of each pair of twisted-pair feeder pair twist and four pairs of twisted-pair feeders
It is identical that (or multipair) collection, which twists direction together, and the twisted-pair feeder produced in this way can occur, from torsional deformation, to lean on rubber packet
Cover makes four pairs of multiple twins be twisted together by force, and over time, difference variation and rubber aging, rubber is to the attached of twisted-pair feeder
Put forth effort to decline, such twisted-pair feeder, gradually to without from the transformation of the state of torsion, to keep pair twist string pitch elongated, makes biography in this way from the state of torsion
Defeated signal quality is greatly reduced, and keeps backbone network speed slack-off.
Invention content
The technical problem to be solved by the present invention is to：A kind of twisted-pair cable and preparation method thereof is provided, can avoid above-mentioned
The problem that signal declines and backbone network speed is slack-off is transmitted because caused by pair twist string pitch is elongated.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of preparation method of twisted-pair cable, includes the following steps：
(1) a plurality of twisted-pair feeder is taken, every two twisted-pair feeders are subjected to first time pair twist, obtain at least four pairs of twisted-pair feeder pair；
It (2), then will be second by every two pairs of twisted-pair feeders of at least four pairs of twisted pairs to carrying out second of pair twist
All twisted-pair feeders obtained after pair twist are twisted edge with second of pair twist side in the opposite direction；
(3) step (2) stranded twisted-pair feeder is obtained into the twisted-pair cable to carrying out insulating wrapped.
A kind of twisted-pair cable is prepared using the preparation method of above-mentioned twisted-pair cable.
The beneficial effects of the present invention are：
In the preparation of the twisted-pair cable of the present invention, each pair of twisted-pair feeder is to carrying out the direction and the of pair twist (second of pair twist)
The direction that all twisted-pair feeders obtained after secondary pair twist twist together concentration is twisted-pair feeder that is opposite, producing in this way
Nothing is at from torsion state.Insulating coating is little to the attachment force effect of twisted-pair feeder.Over time, difference variation and glue
Skin aging, so twisted-pair feeder is to being constantly in without from torsion state, the pitch of twisted-pair feeder not will produce variation, the transmission quality of signal
Also constant, network speed will not be slack-off.
Specific implementation mode
To explain the technical content, the achieved purpose and the effect of the present invention in detail, it is explained below in conjunction with embodiment.
The design of most critical of the present invention is：Each pair of twisted-pair feeder is designed to carrying out the direction and the of pair twist (second of pair twist)
The direction that all twisted-pair feeders obtained after secondary pair twist twist together concentration is opposite, makes twisted-pair feeder to being constantly in nothing
From the state of torsion.
The present invention provides a kind of preparation method of twisted-pair cable, includes the following steps：
(1) a plurality of twisted-pair feeder is taken, every two twisted-pair feeders are subjected to first time pair twist, obtain at least four pairs of twisted-pair feeder pair；
It (2), then will be second by every two pairs of twisted-pair feeders of at least four pairs of twisted pairs to carrying out second of pair twist
