Detailed description of the invention
Fig. 1 is a kind of anti-cross-section diagram for crossing electric heating cable of type variable of high deflection proposed by the present invention.
Specific embodiment
In the following, technical solution of the present invention is described in detail by specific embodiment.
As shown in FIG. 1, FIG. 1 is a kind of anti-cross-section diagrams for crossing electric heating cable of type variable of high deflection proposed by the present invention.
Referring to Fig.1, the embodiment of the present invention propose a kind of high deflection type variable it is anti-cross electric heating cable, comprising: cable core 1 with
And successively it is coated on wrapping layer 2, shielded layer 3, inner sheath 4 and the oversheath 5 of 1 periphery of cable core, in which:
Oversheath 5 is made by elastic material, so that oversheath 5 has good elastic property.Oversheath 5 is equipped with
Multiple circumferential directions are uniformly distributed and linear extension groove along its length；Groove is from the side wall of oversheath 5 to 1 direction concave shape of cable core
At equipped with the movable block 6 extended in the same direction with it in groove, and movable block 6 is solid close to the side of groove slot bottom and the bottom wall of groove
It is fixed；Spacing is reserved between the inner peripheral surface of oversheath 5 and the outer peripheral surface of inner sheath 4 to form ring cavity, and ring cavity is interior and is located at any
One groove is equipped with the deformable body 7 extended in the same direction with movable block 6 close to the side of inner sheath 4；Deformable body 7 is by thermal expansion material
It forms, and the two sides of 7 extending direction of deformable body are respectively equipped with the first limit plate 9, the second limit plate 10；First limit plate 9, second
Limit plate 10 is made by hard material, and the two side close to each other reclines with deformable body 7, and the two is close to inner sheath
4 side is fixed with inner sheath 4.
The present invention operates in such a way: movable block 6 is arranged in groove, protects outside by the way that groove is arranged on oversheath 5
Deformable body 7 is set between set 5 and inner sheath 4, and fixes movable block 6 and the bottom wall of groove, makes deformable body 7 by thermal expansion material
It forms, and the side of deformable body 7 and inner sheath 4 are fixed, the bottom surface of the other side and groove is fixed.In use, working as cable temperature
When more than predetermined value, 7 expanded by heating of deformable body is to push the bottom surface outwardly convex of groove, to increase cable heat dissipation area, simultaneously
The movable block 6 that the groove of evagination pushes it internal is displaced outwardly, with using the movable block 6 moved radially by its around the cable
He elapses cable to side, to guarantee that the cable periphery has certain airspace.In addition, by the two of deformable body 7
The first limit plate 9, the second limit plate 10 is arranged in side, to be cooperated using the first limit plate 9, the second limit plate 10 to deformable body
7 carry out circumferential limits so that deformable body 7 in expanded by heating can only circumferentially extending improved with enhancing the amount of movement of movable block 6
The effective rate of utilization of its span.
From the foregoing, it will be observed that a kind of type variable of high deflection proposed by the present invention is anti-to cross electric heating cable, it can be according to its internal heat
The variation of amount makes its external structure make corresponding change automatically, so that it accelerates heat dissipation, and topology layout is reasonable.
In addition, inner sheath 4 is made by hard material in the present embodiment, so that inner sheath 4 has good structure steady
It is qualitative, it is unlikely to deform.It, can only be to the lateral expansion of inner sheath 4, to further increase to deformable body 7 when so that deformable body 7 being heated
The effective rate of utilization of thermal expansion amount.
In the present embodiment, supporter 8 is equipped in ring cavity and between two deformable bodys 7 of arbitrary neighborhood；Supporter 8
Side and inner sheath 4 it is fixed, side and oversheath 5 far from inner sheath 4 are fixed.And in the present embodiment, supporter 8 is by warm
Shrink-down material is made, when cable temperature is more than predetermined value, 8 heat shrinkable of supporter pull oversheath 5 with to inner sheath 4
Direction bullet becomes, so that the outer peripheral surface in oversheath 5 forms several channels that are circumferentially uniformly distributed and extending longitudinally along the cable, with
Using the channel ventilation and heat of formation, to further speed up the cooling rate of cable.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
