Specific embodiment
The invention is further described with the following Examples.
In the present embodiment, the manufacturing method of collection twisted wire 2 successively includes the following steps.
Pair twist step: being shown in Fig. 1, (can be two conductor lines with insulating protective layer by copper with traditional pair twister
It is manufactured, it is also possible to conductor lines made of other conductive materials such as aluminium, as long as electric conductivity is met the requirements) along clockwise
The mutual back twist in direction is twisted, to form twisted pair 1.Wherein the multiple twin pitch of twisted pair 1 presses standard strict control.It is walked in pair twist
In rapid, the twisted mode of back twist is that two conductor lines are twisted back twist in the counterclockwise direction again along clockwise direction repeatedly, so
Repeatedly after n times, two conductor lines are twisted molding along clockwise direction again, to ensure every conductor lines during the twisting process not
It is produced from twisting strain, making twisted pair 1 is straight spiral path.
1 encapsulation steps of twisted pair: with aluminium film 11 wound on the outer layer of every twisted pair 1, so that twisted pair 1 is enveloped, with
Outer signals interference is isolated.
Collection twists step: seeing Fig. 1 and Fig. 2, the twisted pair 1 after taking four claddings is each passed through four twisted pairs 1 traditional
It after four capstan winches of four disk stranding machine A, is linked on traditional single-deck stranding machine B jointly, stranding machine B is four 1 edges of twisted pair
It is counterclockwise stranded on skeleton 3, realizes that collection twists, form collection twisted wire 2.Collect twisted wire 2 during twisted, stranding machine B is every
It is twisted once enclosing one collection strand pitch of formation on collection twisted wire 2, once being formed, stranding machine B is just from its line outlet handle for collection strand pitch
Collect twisted wire 2 and release the length that a collection twists pitch, realizes outlet.Collect twisted wire 2 constantly to move ahead during outlet to traction four
Twisted pair 1 moves ahead.
Since collection twists the direction of lay in step and the direction of lay in pair twist step on the contrary, the collection that collection twists step twists process
Back twist effect can be generated to every twisted pair 1, so that twisted pair 1 itself is scattered to change pair twist pitch, lead to the number of twisted pair 1
Decline according to transmittability.It in order to solve the problems, such as that above-mentioned pair twist pitch changes, is twisted in step in collection, needs plus turn round sub-step:
Stranding machine B release collection twist after pitch and not yet enter a new round it is twisted before, stranding machine A is to every twisted pair 1 for control
It is first twisted a circle (summary plus torsion) along clockwise direction.By first being enclosed to every twisted pair 1 plus torsion one, in stranding machine B along the inverse time
During the twisted circle in needle direction, the lucky back twist one under back twist effect of every twisted pair 1 is enclosed, and torsion is added mutually to support with back twist
Disappear, the pair twist pitch of every twisted pair 1 is made to keep full-length constant, to solve the problems, such as that above-mentioned pair twist pitch changes, protects
Hinder the data transmission capabilities of twisted pair 1.
Further, since collection twists the direction of lay in step and the direction of lay in pair twist step on the contrary, collection strand step will not
Cause twisted pair 1 from twisting strain, therefore can make twisted pair 1 keep straight, finally make whole collection twisted wire 2 keep straight, rather than
Tradition collection twisted wire 2 is easily bent in its natural state like that, this since collection twisted wire 2 often needs guiding through pipeline during the installation process
Straight collection twisted wire 2 just has big advantage in poling operation, worker can be facilitated to construct.
It should be noted that seeing Fig. 2, in order to ensure stranding machine A's plus a circle is turned round, stranding machine B just follows a twisted circle,
Be separately installed with encoder A1 and decoder B1 on stranding machine A and stranding machine B, encoder A1 and decoder B1 by data line into
Row communication.It is turned round in sub-step adding, encoder A1 twisted pair wire machine A's adds torsion circle number to be counted, and real-time Transmission is to decoder
B1, by being transferred to the electric-control system of stranding machine B itself after decoder B1 decoding, electric-control system item knows strand according to the data received
The capstan winch of line machine A after the twisted circle of direction S, just starts the capstan winch of stranding machine B along the twisted circle of direction N, to realize same
Step control.
Encapsulation steps: being the prior art due to being the step, herein in molding 2 external sheath insulated cladding of collection twisted wire
It does not repeat them here.
It is twisted in step in collection, four twisted pairs 1 are stranded on skeleton 3.See Fig. 2, middle skeleton 3 uses elastic rubber material
Material is made, and makes it have certain elasticity.Skeleton 3 is whole to be risen along spiral path, and pitch is equal with collection strand pitch, from
And it is adapted to.The shape of skeleton 3 specifically includes four mutually perpendicular support chips 33, and one end of each support chip 33 intersects at same
Place is supporting zone between adjacent support chip 33 to form the central axis of skeleton 3.The other end court of every support chip 33
Barrier flaps 32 are extended in its left side, and barrier flaps are tilted towards the direction close to central axis, and part covers support below
Region is embedded in supporting zone for twisted pair wire so that there are openings.Barrier flaps 32 can play the twisted pair 1 in supporting zone
Effect of contraction, accordingly even when the insulated cladding aging deformation that collection twisted wire 2 coats, barrier flaps 32 can also assist constraint twisted pair
1 does not depart from skeleton 3, to reduce deflection, ensures communication quality.Since barrier flaps 32 are only stretched from the left side of support chip 33
Out, the skeleton 3 of the present embodiment is ensureing that opening is sufficiently large compared with the skeleton in the first patent document CN206194409U of our company
In the case where, monolithic barrier flaps 32 can be made longer, since the material of barrier flaps 32 is elastic rubber, barrier flaps 32
Length is longer, and its elasticity is better, therefore twisted pair 1 directly can be pressed into supporting zone from opening, stops the wing during indentation
Piece 32 is first squeezed toward inner bending, the elastic reset after twisted pair 1 is successfully pressed into supporting zone, and telescopiny is very convenient.By
It elastic can be bent in telescopiny in barrier flaps 32, therefore its length can not make strict control, machining accuracy can suitably be put
Width, processing cost are lower.In addition, stranding machine B in the counterclockwise direction be twisted during, twisted pair 1 under effect of inertia according to
On the left side for leaning against support chip 33, at this time due to having barrier flaps 32 on the left side of support chip 33, barrier flaps 32 form one
A interior curved hook, avoids twisted pair 1 from skidding off outside skeleton 3.Further, barrier flaps 32 are specially arc-shaped, the circular arc
The center of circle is located on central axis, be on the one hand it is arc-shaped more can resistance to stress, on the other hand be then that will not externally generate water chestnut.It is preferred that
Ground sets the length of arc-shaped barrier flaps 32 enough to long to make the more than half Support covered below of barrier flaps 32
Domain, in this way, the point M on twisted pair wire periphery farthest away from central axis is also blocked fin 32 after twisted pair wire is embedded into supporting zone
It covers, barrier flaps 32 not only have effect of contraction at this time, moreover it is possible to twisted pair wire be protected to hit from external force as shell；Simultaneously
End after being extended through point M due to arc-shaped barrier flaps 32 can be collapsed to central axis, barrier flaps 32 can be convenient for toward inner bending.
Available with next part twisted wire 2 using the above production technology: the collection twisted wire 2 includes four pairs being embedded on skeleton 3
Twisted wire 1, every 1 themselves straight of twisted pair rise along spiral path, wherein the twisted direction of every twisted pair 1 and collection twisted wire 2
It is twisted contrary, to keep whole collection twisted wire 2 not bend straight.It is coated with aluminium film 11 on the outside of twisted pair 1, each item can be prevented
Mutual magnetic perturbation between twisted pair 1.The whole external sheath of collection twisted wire 2 has insulated cladding, the effect of its protection solid of insulated cladding.
It should be noted that four disk stranding machine A can change into more single-decks or double plate stranding machine carry out using.Due to twisted wire
Machine A, B are the prior arts, and the specific structure of stranding machine A, B and wherein capstan winch can refer to existing stranding machine and its capstan winch, this
Wen Buzuo is repeated.
