Embodiment 1

[0037] Such as Figure 1 to Figure 3 As shown, the present invention provides a high-temperature constant power electric heating cable, including: an insulating filling tape 1, and a perforation 11 and a wire 12 are arranged at intervals in the insulating filling tape 1, and the outer surface of the wire 12 and the insulation A composite layer 13 is arranged between the filling strips 1, and a heat conduction layer 14 is arranged between the outer surface of the composite layer 13 and the insulating filling strip 1. In the length direction of the insulating filling strip 1, the perforation 11 It has a first port and the second port; an elastic contraction part 2, one end of the elastic contraction part 2 is connected to the first port of the perforation 11, and the other end of the elastic contraction part 2 is connected to the At the second port of the through hole 11, the elastic contraction member 2 is in a contracted state in the through hole 11.

[0038] It can be unders...

Embodiment 2

[0044] The difference between this embodiment and the foregoing embodiment is:

[0045] In some embodiments of the present invention, the inner wall of the perforation 11 is provided with a heat insulating layer 3 surrounding the elastic contraction member 2 . Thus, the heat generated by the wire 12 is prevented from damaging the elastic contraction member 2 .

[0046]In some embodiments of the present invention, in the length direction of the insulating filling tape 1, a plurality of first positioning portions 4 are arranged at intervals on the outer wall surface of the heat insulating layer 3, and each of the first positioning portions 4 all protrude into the insulating filling strip 1 to limit the displacement between the insulating filling strip 1 and the heat insulating layer 3 . Thus, the stability of the heating cable is improved.

[0047] In some embodiments of the present invention, each of the first positioning portions 4 includes a plurality of first positioning p...

Embodiment 3

[0051] The difference between this embodiment and the foregoing embodiment is:

[0052] In some embodiments of the present invention, there are a plurality of elastic contraction members 2, and a plurality of perforations 11 are provided at intervals in the insulating filling tape 1, and a plurality of elastic contraction members 2 are arranged in one-to-one correspondence. Inside a plurality of said perforations 11. Thus, the elastic force of the elastic contraction member 2 is improved to better protect the electric heating cable.

[0053] In some embodiments of the present invention, in the length direction of the insulating filling tape 1, a plurality of second positioning parts 5 are arranged at intervals on the outer wall surface of the heat conducting layer 14, each of the second positioning parts 5 Both protrude into the insulating filling strip 1 to limit the displacement between the insulating filling strip 1 and the heat conducting layer 14 . Thus, the stability o...

Abstract

The invention provides a high-temperature constant-power electric tracing band, and the electric tracing band comprises an insulating filling band which is internally provided with through holes and wires at intervals, wherein a composite layer is arranged between the outer surface of the wire and the insulating filling tape, a heat conduction layer is arranged between the outer surface of the composite layer and the insulating filling tape, and the through hole is provided with a first port and a second port in the length direction of the insulating filling tape; an elastic contraction piece,wherein one end of the elastic contraction piece is connected to the first port of the through hole, the other end of the elastic contraction piece is connected to the second port of the through hole, and the elastic contraction piece is in a contraction state in the through hole. According to the invention, the elastic contraction piece in a contraction state is arranged in the insulating filling tape, so the elastic contraction piece can counteract the part of tension through elastic force when the electric tracing tape bears the tension in the length direction of the insulating filling tape, thereby reducing the tension borne by the electric tracing tape, and achieving the purpose of protecting the electric tracing tape; therefore, the phenomenon that the heat tracing band is pulled inthe installation process is avoided.

Description

technical field [0001] The invention relates to the technical field of heating cables, in particular to a high-temperature constant power electric heating cable. Background technique [0002] In related technologies, the electric heating cable itself is a heating cable, which passes through a certain resistance and forms an effective loop to achieve the effect of heating or heat tracing. The electric heating cable is usually wound on the pipe to achieve the purpose of heating and heat preservation, but it is inevitable that the purpose of pulling the heating cable will appear during the installation process, which will cause the phenomenon of pulling the heating cable during the installation process and affect the work of the heating cable stability. [0003] Therefore, it is necessary to develop a high temperature constant power electric heating cable for solving at least one of the above technical problems. Contents of the invention [0004] The purpose of the present ...
