Description
Technical field
The utility model is related to a kind of cable center's filler, more particularly to a kind of multicore cable center-filled thing.
Background technology
Cable is that power equipment majority uses polyphase source for transmitting electric energy or control signal, so power consumption
Cable needs many cores to work simultaneously.Many cores are twisted together in production multicore cable is made, this process is called
Stranding, the space-consuming of cable when the cumulative volume that stranding can reduce cable can also reduce work, and reduce material use
Amount, reduces production cost.In cable core stranding, there is larger space inside it, be at this moment accomplished by using packing material
Filled, to ensure the stabilization and rounding of the construction of cable.At present in multicore cable stranding, filled out used in center
Fill for circular packing or other circular materials, position, which easily changes, between so each core of cable cabling causes electricity
Cable structure is unstable, outward appearance not rounding.
Utility model content
The purpose of this utility model is that solving above-mentioned prior art is present at present in multicore cable stranding, center
It is used to be filled with position between circular packing or other circular materials, so each core of cable cabling and easily occur
Change causes that the construction of cable is unstable, outward appearance not rounding the problem of there is provided a kind of multicore cable center-filled thing.
The utility model solves the technical scheme that its technical problem used：A kind of multicore cable center-filled thing, makees
For the support of target cable core, it is characterised in that：The cross section of the filler is in polygon-shaped, and the polygonal side number is
Even number, the polygon includes some long sides and some short sides, and the two ends on the long side are connected with short side, the short side
Two ends Jun Yuchang sides are connected, and described long side is the arc caved inward, and described short side is the arc of evagination, described many
The arc caved inward of side shape and matching for target cable core, multicore cable include thick core electric wire and thin core electric wire, institute
Thick core electric wire is stated to fit with the arc caved inward；Every thin core electric wire is disposed between two thick core electric wires, institute
The central point of the central point of filler and the outermost distance value of thick core electric wire and the filler is stated with thin core electric wire most
The distance value in outside is equal.There is arc-shaped concave on the surface of the utility model statement, and core is just put into inside concave surface during stranding,
Just it is less likely to occur movement into the position of cable core, the structure of such cable will more stablize and roundness can also be improved.
Preferably, the outermost and the outermost of thick core electric wire of the oversheath of the target cable core and thin core electric wire
Abut.In this way, can be stuck in well in overcoat.
Preferably, the center of the filler offers a fixing hole, the fixing hole is triangular in shape, quadrangle or
Kidney ellipsoid.So setting can allow thin core electric wire and thick core electric wire properly to be fitted in horizontal positioned the utility model.
Preferably, the corresponding central angle angle of the arc caved inward is at least above 45 °.The utility model is so
Set, angle is too small to influence whether fixed effect.
Substantial effect of the present utility model is：There are arc-shaped concave, stranding in the filler surface of the utility model extrusion
When core be just put into inside concave surface, be just less likely to occur movement into the position of cable core, the structure of such cable will be more
Stable and roundness can also be improved.
Brief description of the drawings
The structural representation when one kind for the filler that Fig. 1 extrudes for the utility model is used；
Fig. 2 is another structural representation of the present utility model.
In figure：11st, filler, 12, thick core electric wire, 13, thin core electric wire, 14, oversheath, 21, fixing hole.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made further specifically
It is bright.
A kind of multicore cable center-filled thing (referring to accompanying drawing 1), as the support of target cable core, the filler 11
Cross section is in polygon-shaped, and the polygonal side number is even number, and the polygon includes some long sides and some short sides, institute
The two ends for stating long side are connected with short side, the two ends Jun Yuchang sides connection of the short side, and described long side is what is caved inward
Arc, described short side is the arc of evagination, and the polygonal arc caved inward matches with target cable core,
Multicore cable includes thick core electric wire 12 and thin core electric wire 13, and the thick core electric wire fits with the arc caved inward；
Every thin core electric wire is disposed between two thick core electric wires, the central point of the filler and thick core electric wire it is outermost away from
Central point from value and the filler is equal with the outermost distance value of thin core electric wire.The oversheath of the target cable core
14 abut with the outermost of thin core electric wire and the outermost of thick core electric wire.The center of the filler offers a fixing hole
21, the fixing hole is circle.The corresponding central angle angle of the arc caved inward is at least above 45 °.It is overall to include three
The long short side of side three, the three long side is arranged at intervals with three short side, and the three long side is the arc caved inward of equal length
Shape, three short side is the arc of the outwardly convex of equal length, and the arbitrarily long side and the angle of any short side are homogeneous
Deng.
In the present embodiment, there is arc-shaped concave on the filler surface of generation, and core is just put into inside concave surface during stranding, into
The position of cable core is just less likely to occur movement, and the structure of such cable will more stablize and roundness can also be improved.
Embodiment 2：
The present embodiment is substantially the same manner as Example 1, and difference is (referring to accompanying drawing 2), the fixing hole is triangular in shape,
Quadrangle or kidney ellipsoid 21.
In addition to above form, other various cable cores can also be corresponded to and be not limited to power line or signal wire,
Can also be ground wire, shielding line.Can be with correspondence 4 thick 4 carefully or in the form of other quantity in the present embodiment, corresponding modification
Reach.
Embodiment described above is a kind of preferably scheme of the present utility model, not makees any to the utility model
Formal limitation, also has other variants and remodeling on the premise of without departing from the technical scheme described in claim.
