Feature can express or implicitly include one or more this feature.In the description of the invention, unless separately
It is described, " multiple " is meant that two or more.
, it is necessary to explanation, unless otherwise clearly defined and limited, term " is pacified in the description of the invention
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, or integratedly
Connection；Can mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary,
Can be two connections of element internal.For the ordinary skill in the art, can be by concrete condition understanding
State concrete meaning of the term in the invention.
Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of special deconcentrator of railway digital signal cable star quad stranding line, as shown in Figures 1 to 3, including support body；Described
Be symmetrically arranged with crossed beam trunking 2 on support body 1, and on the support body correspondence crossed beam trunking be provided with for star quadding machine on block
The positioning step 3 that groove coordinates.
Above-mentioned support body 1 is made of wolfram steel.In addition, supporting body structure in the form of annular discs, structural strength is high, symmetry
Good, stability is splendid, is difficult unstability, upset in cable stranding process.
It should be noted that compared to existing cross deconcentrator, its cross structure was both played a supporting role, was also risen
To the effect of separated time, the angle on cross leaves excessive activity to single line, therefore, easily occur during process
Rock, it is highly unstable.
The deconcentrator that the invention is provided, there is provided the crossed beam trunking passed through for single line, also, crossed beam trunking has been arranged on solely
On vertical support body, positioning step is played and positioned with star quadding machine and fixed effect, and supports the crossed beam trunking on body to play
The effect of separated time, on the premise of line was not influenceed, effective constraint is formed to single line, and single line will not be upper and lower in U-type groove
Left and right is random to rock.
The above-mentioned U-shaped structure of crossed beam trunking.It should be noted that crossed beam trunking and the transition junction of support body, use
Round-corner transition, it is to avoid single line weares and teares during process with the corner angle at support body fluting, it is to avoid incised wound single line.
Compared to traditional cross structure deconcentrator, the invention breaches technical limitation, be not as
Crossed beam trunking is directly opened up on cross structure shown in Fig. 3, but the line excessively of U-shape structure is separately provided on support body
Groove, the advantage of so design is that during twisted wire, crossed beam trunking position will not occur stress concentration, strong with structure higher
Degree and stability.
Above-mentioned support body is laid with 4 crossed beam trunkings along its circumferencial direction.In stranding process, 4 single lines of star quad stranding line
It is separately positioned in four U-type grooves, effectively separates.
Positioning step 3 described in one, correspondence and the draw-in groove of star quadding machine are equipped between crossed beam trunking described in every two, are supported on body
Positioning step be generally also what is be uniformly arranged, it is circular or polygonal locating dowel that positioning step 3 preferably uses cross section.
It is pointed out that the structural strength in order to further improve this deconcentrator, can will support body geometric center
Position Design into the bulge-structure 4 for thickening, as shown in Fig. 2 the middle part bump height highest of bulge-structure 4, to support this
External edge gradually transition, bump height is gradually reduced.
Specifically, above-mentioned bulge-structure 4 uses the transition of arc chord angle 5 with the groove bottom part of U-type groove.During process, respectively
Single line has to the trend moved at the geometric center of this deconcentrator, such structure design, single line and the circular arc for supporting body
Angle part contacts, it is ensured that single line accurate positioning on this deconcentrator, it is ensured that process operation is smoothed out, and single line is close to arc chord angle
Position, process process stabilization is efficient.
In stranding process, 4 single lines are separately positioned in four U-type grooves, and four steps on support body are fixed respectively
In the draw-in groove of high speed star quadding machine, compared with the deconcentrator of existing " ten " font, single line will not shake up and down in U-type groove
Dynamic, with Stability Analysis of Structures, symmetry is good, can be effectively improved the capacitive unbalance to earth and Capacitance Coupled of cable, to greatest extent
Cable crosstalk, the index such as decay are reduced, the performance such as interferes between strengthening heart yearn.In addition, the deconcentrator simple structure, it is easy to plus
Work, with larger practical value.
The preferred embodiment of the invention is the foregoing is only, creation is not intended to limit the invention, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
