This design provides a preferred insulation protection structure design, and the insulation pad is attached to the bottom surface of the bending connecting part, i.e., the side surface adjacent to the heating plate, thereby providing effective insulation, and the structure is simple and has good insulation protection effect. On this basis, a preferred structure is that the width of the insulation pad is greater than the width of the bending connecting part, and a certain cladding is formed on the bottom surface of the bending connecting part, thereby further improving the insulation performance.
[0008] As a preferred scheme, the insulation protection structure is an insulation protection sleeve sleeved on the outer periphery of the bending connecting part, and a preset interval is provided between the bottom end surface of the insulation protection sleeve and the heating plate of the heater.

[0025] The utility model provides a kind of heater connecting terminal design with better insulation safety, and the insulating protective structure is arranged between the bending connecting portion 2-3 position before connecting terminal and heating plate contact 1-1 contact conduction and heating plate 1, the protective property of the structure is improved by the structure, effectively blocks the abnormal ion migration channel that appears due to humidity change etc.
[0026] In the technical scheme provided by the embodiment, the insulating protective structure is an insulating gasket attached to the bottom surface of the bending connecting portion 2-3, and a preset distance is provided between the bottom end surface of the insulating gasket and the heating plate 1. This design provides a preferred insulating protective structure design, and the insulating gasket is attached to the side surface adjacent to the heating plate 1 on the bottom surface of the bending connecting portion 2-3. The structure provides effective insulation, and the structure is simple and has good insulating protective effect. On this basis, the preferred structure is that the width of the insulating gasket is greater than the width of the bending connecting portion 2-3, and a certain cladding is formed on the bottom surface of the bending connecting portion 2-3, further improving the insulation performance.
[0027] In the technical scheme provided by the embodiment, the insulating protective structure is an insulating protective sleeve 3 sleeved on the outer periphery of the bending connecting portion 2-3, and a preset distance is provided between the bottom end surface of the insulating protective sleeve 3 and the heating plate 1 of the heater. This design provides another preferred insulating protective structure design, which can be regarded as a further extension and optimization of the above structure. The insulating protective sleeve 3 can be integrally sleeved on the outside of the bending connecting portion 2-3, and provides insulating protection at different angles.
[0028] In the technical scheme provided by the embodiment, one side end surface of the insulating protective sleeve 3 abuts against the end surface of the insulating sleeve 2-2. This design further improves the insulation performance of the insulating protective sleeve 3. The end surface directly abuts against the end surface of the insulating sleeve 2-2, further reducing the area of the bending connecting portion 2-3, so that the entire structure of the bending connecting portion 2-3 is wrapped, greatly improving the insulation performance of this part.
[0029] In the technical scheme provided by the embodiment, the bending connecting portion 2-3 is provided with a through hole structure 2-4, and the inside of the insulating protective sleeve 3 is fixed to the through hole structure 2-4. In order to increase the connection firmness between the insulating protective sleeve 3 and the bending connecting portion 2-3, and avoid the insulating protective sleeve 3 from falling off the bending connecting portion 2-3, the complexity of the surface structure of the bending connecting portion 2-3 is increased, and the firmness of the fixation between the insulating protective sleeve 3 and the bending connecting portion 2-3 is effectively improved by the provision of the through hole structure 2-4.

The design provides a relatively simple insulating protective sleeve 3 design, which is directly sleeved on the bending connecting part 2-3 through the insulating film, and also has good insulation performance.

The design provides another optional insulating protective sleeve 3 design, which directly completes the insulation structure setting by spraying the insulating paint layer on the surface of the bending connecting part 2-3. The insulating film has better fixing ability, and is not easy to fall off after coating. However, due to the characteristics of the paint layer itself, the durability may be slightly inferior after long-term use.
[0033] In the technical scheme provided by the embodiment, the insulating protective structure is an insulating sheet layer attached and fixed to the surface of the heating plate 1, and the upper surface of the insulating sheet layer is provided with a preset distance from the bending connecting part 2-3. The design provides an insulation design different from the above various insulating protective sleeves 3. The insulation structure is not set on the pin structure, but is attached and fixed to the surface of the heating plate 1. The insulation ability can be equivalent, and the difference is that the processing and forming modes are different, which enhances the flexibility and diversity of the insulation structure processing and forming.

The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
