[0021] Reference Figure 1-2The present invention proposes a foldable electric heating tape assembly, including a plurality of sections of electric heating tape bodies 1 electrically connected in sequence and a connector 2 for sealingly electrically connecting two adjacent sections of the electric heating tape bodies 1. The connector 2 includes two rotatably electrically connected shells 3, and the two shells 3 are electrically connected to the two electric heating tape bodies 1 respectively.

[0022] When in use, for some objects to be heated with corners, place the connector 2 at the corners. Figure 2 , the two shells 3 are rotated relative to each other, so that the two electric heating tape bodies 1 connected to the two shells 3 can fit with the two side walls of the corner respectively, thereby expanding the use range of the electric heating tape body 1.

[0023] In the above embodiments, specific reference is made to Figure 3-4 In order to realize the rotational connection between the two shells 3, both sides of the shell 3 have protrusions 31, and the protrusions 31 on the two shells 3 are rotationally connected. In addition, in order to make the two shells 3 sealed, the two shells 3 are sleeved with the same flexible sealing sleeve 7, and the flexible sealing sleeve 7 is made of self-repairing material. One end of the flexible sealing sleeve 7 is sleeved on one shell 3, and the other end is sleeved on the other shell 3. In order to improve the sealing type of the flexible sealing sleeve 7, heat shrinkable films are also sleeved on both ends of the flexible sealing sleeve 7. After the two electric heating belt bodies 1 are connected, the heat shrinkable film is heated so that the heat shrinkable film is firmly sleeved on the shell 3 and the flexible sealing sleeve 7.

[0024] It should be further explained that, in order to achieve the connection between the shell 3 and the electric heating tape body 1, a chamber 32 for accommodating the electric heating tape body 1 is horizontally opened on the shell 3. After the installation is completed, sealant can be poured into the chamber 32 to relatively fix the electric heating tape body 1 and the shell 3 and to achieve the sealing between the electric heating tape body 1 and the shell 3. In addition, two conductive blocks 4 that can be in contact and electrically connected with the electric heating tape body 1 are fixed in the chamber 32. The outer end of the conductive block 4 on one shell 3 extends to the outside of the shell 3 through the notch on the shell 3 and is rotatably connected to the corresponding conductive block 4 on the other shell 3. The two copper core wires 11 on the two electric heating tape bodies 1 are electrically connected to the conductive blocks 4 respectively. The rotation axes of the two groups of conductive blocks 4 are colinear with the rotation axes between the two shells 3. Therefore, when the shell 3 is rotated, the conductive blocks 4 rotate together, and the bending of the electric heating tape body assembly is achieved without the need to bend the copper core wires 11, thereby better protecting the copper core wires 11 and avoiding bending and breakage of the copper core wires 11.

[0025] To facilitate the electrical connection of the two electric heating tape bodies 1, the chamber 32 includes a first slot portion 321 arranged in a horizontal direction and used to accommodate the tail end of the electric heating tape body 1, and two second slot portions 322 respectively used to accommodate the two copper core conductors 11 on the electric heating tape body 1. The inlet ends of the two second slot portions 322 are connected to the outlet end of the first slot portion 321, and the two conductive blocks 4 are respectively located in the two second slot portions 322.

[0026] In the above embodiment, two through holes 33 are vertically opened on the top wall of the shell 3, and the two through holes 33 are respectively connected to the two second groove parts 322. When injecting sealant into the chamber 32, it can be injected into the chamber 32 through one of the through holes 33, and the sealant flows in the chamber 32 toward the other through hole 33, and the air in the chamber 32 is discharged through the other through hole 33.

[0027] In order to make the copper core conductor 11 and the conductive block 4 fit more closely, the electric heating tape assembly proposed in the present invention further includes a fixing member 5 for relatively fixing the copper core conductor 11 and the conductive block 4 .

[0028] Specifically, the fixing member 5 can be a screw, and an internal thread that is adapted to be screwed with the external thread on the screw is provided in the through hole 33, and the conductive block 4 is located on the bottom wall of the second slot body portion 322. When in use, the screw is rotated, and the bottom end of the screw extends into the second slot body portion 322 through the through hole 33, and applies a downward force to the copper core wire 11, so that the copper core wire 11 fits tightly with the conductive block 4. In addition, when the screw is screwed in, the screw closes the through hole 33, and can also prevent the sealant from flowing out of the through hole 33 when the component is moved.

[0029] The electric heating tape assembly proposed in the present invention also includes a sealing ring 6, which is sleeved inside the inlet end of the first groove body portion 321, and the sealing ring 6 can be adaptably mounted outside the electric heating tape body 1. When pouring glue, the sealing ring 6 can prevent the glue from flowing out through the inlet end of the first groove body portion 321.

[0030] In the above embodiment, the inner ring of the sealing ring 6 has a tapered portion, and the end of the tapered portion is inclined toward the outlet end of the first groove portion 321, thereby reducing the friction force when the electric heating belt body 1 enters the chamber 32 and increasing the friction force when the electric heating belt body 1 goes out of the chamber 32. In addition, the glue can also give the sealing ring 6 an outward pressure, which can also increase the friction force when the electric heating belt body 1 goes out of the chamber 32, thereby reducing the possibility of separation between the electric heating belt body 1 and the shell 3.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
