Between deformable body is set, and fix the bottom wall of movable block and groove, deformable body made to be formed by thermal expansion material, and the one of deformable body
Side is fixed with inner sheath, and the bottom surface of opposite side and groove is fixed.In use, when cable temperature is more than predetermined value, deformable body
Expanded by heating is to promote the bottom surface outwardly convex of groove, and to increase cable heat dissipation area, while the groove of evagination is promoted inside it
Movable block be displaced outwardly, other cables around the cable to be elapsed to one side using the movable block that moves radially, with
Ensure that the cable periphery has certain airspace.Meanwhile by setting the first limiting plate, the second limit in the both sides of deformable body
Position plate carries out deformable body circumferential /V, so that deformable body is heated to cooperate using the first limiting plate, the second limiting plate
During expansion can only circumferentially extending, to enhance the amount of movement of movable block, improve the effective rate of utilization of its span.
In conclusion 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.
Description of the drawings
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 scheme is described in detail by specific embodiment.
As shown in Figure 1, 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.
With reference to Fig. 1, a kind of type variable for high deflection that the embodiment of the present invention proposes is anti-to cross electric heating cable, including：Cable core 1 with
And lapping layer 2, shielded layer 3, inner sheath 4 and the oversheath 5 of 1 periphery of cable core are coated on successively, wherein：
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
Into equipped with the movable block 6 extended in the same direction with it in groove, and bottom wall of the movable block 6 close to the one side of groove slot bottom and groove is consolidated
It is fixed；Spacing is reserved between the inner peripheral surface of oversheath 5 and the outer circumferential surface of inner sheath 4 to form ring cavity, and ring cavity is interior and positioned at arbitrary
One groove is equipped with the deformable body 7 extended in the same direction with movable block 6 close to the one side of inner sheath 4；Deformable body 7 is by thermal expansion material
It forms, and the both sides of 7 extending direction of deformable body are respectively equipped with the first limiting plate 9, the second limiting plate 10；First limiting plate 9, second
Limiting plate 10 is made by hard material, and the two one side close to each other reclines with deformable body 7, and the two is close to inner sheath
4 one side is fixed with inner sheath 4.
The present invention so works：By setting groove on oversheath 5, movable block 6 in groove is set, is protected outside
Deformable body 7 between set 5 and inner sheath 4 is set, and fixes movable block 6 and the bottom wall of groove, makes deformable body 7 by thermal expansion material
It forms, and the one side of deformable body 7 is fixed with inner sheath 4, the bottom surface of opposite side and groove is fixed.In use, work as cable temperature
During more than predetermined value, 7 expanded by heating of deformable body is to promote the bottom surface outwardly convex of groove, to increase cable heat dissipation area, simultaneously
The movable block 6 that the groove of evagination promotes it internal is displaced outwardly, with using the movable block 6 moved radially by its around the cable
He elapses cable to one side, to ensure that the cable periphery has certain airspace.In addition, by the two of deformable body 7
Side sets the first limiting plate 9, the second limiting plate 10, to be cooperated using the first limiting plate 9, the second limiting plate 10 to deformable body
7 carry out circumferential /Vs so that deformable body 7 in expanded by heating can only circumferentially extending, to enhance the amount of movement of movable block 6, improve
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, in the present embodiment, inner sheath 4 is made by hard material, so that inner sheath 4 is steady with good structure
It is qualitative, it is unlikely to deform.It, can only be to the lateral expansion of inner sheath 4, to further improve to deformable body 7 during so that deformable body 7 being heated
The effective rate of utilization of thermal expansion amount.
