Technical Field

[0001] The utility model relates to the technical field of electric heating tapes, in particular to an electric heating tape with variable bending distance at nodes. Background Art

[0002] At present, in the production process of parallel constant power electric heating cables, it is necessary to first manually dig an opening in the combination layer, and then connect the heating wire and the copper wire in parallel outside the combination layer. Then, high-temperature solder is used to increase the contact area at the intersection of the heating wire and the combination layer to achieve the purpose of parallel connection.

[0003] However, the traditional method of high-temperature soldering has some disadvantages. For example, the nodes cannot be bent excessively, which can easily cause the welding point between the heating wire and the copper wire to break, thus affecting the use effect of the electric heating tape.

[0008] A heating wire is spirally wound and arranged between the layer and the protective layer, and the heating wire is provided with a plurality of densified areas;

[0009] A plurality of node openings are evenly distributed on the insulating layer, and each node opening corresponds to a densified area, and the heating wire of each densified area is wound around the copper wire through the node opening to ensure full contact and connection with the copper wire.

[0010] Preferably, the insulating layer is made of a transparent material.
