Native mode is kept when normal.
The present invention proposes a kind of anti-electric heating cable excessively of type variable, including：Cable core and be coated on successively cable core periphery around
Covering, shielded layer, inner sheath and oversheath, wherein：
Oversheath is made by elastic material, and oversheath was equipped with multiple linear extensions along its length and around its week
The uniformly distributed recessed groove of face ring shape, the side wall of each recessed groove from oversheath is recessed to cable core direction to be formed, and in each recessed groove
It is equipped with the bar shaped pushing block extended in the same direction with it；Each bar shaped pushing block is consolidated close to bottom wall of the one side of recessed groove slot bottom with recessed groove
It is fixed；
Between oversheath and inner sheath and positioned at any one recessed groove expander is equipped with close to the one side of inner sheath；It is swollen
Swollen body is the strip structure extended in the same direction with recessed groove, and it is fixed close to the bottom surface of the one side of groove and recessed groove, close
The one side of inner sheath is fixed with inner sheath；Expander is formed by thermal expansion material.
Preferably, inner sheath is made by hard material.
Preferably, the gap between the inner peripheral surface of oversheath and the outer circumferential surface of inner sheath is equipped with obturator.
Preferably, obturator is made by heat-shrinkage material and is fixed respectively with oversheath and inner sheath.
Preferably, recessed groove is cambered surface close to the side of inner sheath one side.
In the present invention, by setting recessed groove on oversheath, bar shaped pushing block in recessed groove is set, and makes bar shaped pushing block
It fixes, makes between oversheath and inner sheath and equal close to the one side of inner sheath positioned at any one recessed groove with the bottom wall of recessed groove
Equipped with the expander being connected with the recessed groove groove bottom and inner sheath, it is the bar shaped knot extended in the same direction with recessed groove to make expander
Structure, and it is formed by thermal expansion material.In use, when cable temperature is more than predetermined value, expander expanded by heating is recessed to promote
The bottom surface outwardly convex of slot is fallen into, to increase cable heat dissipation area, while the recessed groove of evagination promotes bar shaped pushing block to be displaced outwardly, with
Other cables around cable are elapsed to one side, to ensure that cable periphery has certain airspace.The construction of cable
Setting according to the variation of its internal heat its external structure can be made to make corresponding change automatically so that its accelerate heat dissipation or
Recover original state.
Description of the drawings
Fig. 1 is a kind of anti-cross-section diagram for crossing electric heating cable of type variable 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 proposed by the present invention.
With reference to Fig. 1, a kind of type variable of proposition of the embodiment of the present invention is anti-to cross electric heating cable, including：It cable core 1 and coats successively
In the lapping layer 2 of 1 periphery of cable core, shielded layer 3, inner sheath 4 and oversheath 5, wherein：
Oversheath 5 is made by elastic material, and oversheath 5 is equipped with multiple linear extensions along its length and around it
The uniformly distributed recessed groove of circumferential surface annular, the side wall of each recessed groove from oversheath 5 is recessed to 1 direction of cable core to be formed, and each recess
The bar shaped pushing block 6 extended in the same direction with it is equipped in slot；Each bar shaped pushing block 6 close to the one side of recessed groove slot bottom with recessed groove
Bottom wall is fixed, so that bar shaped pushing block 6 can be moved with the movement of recess cell wall.Between oversheath 5 and inner sheath 4 and it is located at
Any one recessed groove is equipped with expander 7 close to the one side of inner sheath 4；Expander 7 is the bar shaped extended in the same direction with recessed groove
Structure, and it is fixed close to the bottom surface of the one side of groove and recessed groove, is fixed close to the one side of inner sheath 4 and inner sheath 4；It is swollen
Swollen body 7 is formed by thermal expansion material, so that it can generate certain stroke when heated.
It is of the invention in use, when cable temperature is more than predetermined value, 7 expanded by heating of expander is to promote the bottom of recessed groove
Towards outer lug, to increase cable heat dissipation area, while the recessed groove of evagination promotes bar shaped pushing block 6 to be displaced outwardly, to utilize item
Shape pushing block 6 elapses other cables around the cable to one side, to ensure that cable periphery has certain airspace；When
When cable heat is restored within predetermined value, expander 7 recovers to original state.
From the foregoing, it will be observed that the setting of the construction of cable can be such that its external structure does automatically according to the variation of its internal heat
Go out corresponding change, so that it is accelerated heat dissipation or recovers original state.
In addition, in the present embodiment, inner sheath 4 is made by hard material, can only be inside during so that expander 7 being heated
The lateral expansion of sheath 4, to improve the effective rate of utilization to 7 thermal expansion amount of expander.
In the present embodiment, the gap between the inner peripheral surface of oversheath 5 and the outer circumferential surface of inner sheath 4 is equipped with obturator 8, and
Obturator 8 is made by heat-shrinkage material and is fixed respectively with oversheath 5 and inner sheath 4, so that cable heat is more than predetermined
During value, obturator 8 can pull oversheath 5 to increase the space between the cable periphery and other cables to tightening on the inside of cable
Greatly, and then increase air circulation face, improve heat dissipation effect.
In the present embodiment, recessed groove is cambered surface close to the side of 4 one side of inner sheath, to facilitate it raised outward.
In addition, the both sides of the extending direction of expander 7 are equipped with for carrying out the limit body of circumferential /V to expander 7,
And the one side of limit body is fixed with inner sheath 4, opposite side and oversheath are against during so that expander 7 being heated, stroke is complete
Portion is used to that bar shaped pushing block 6 to be promoted to move.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
