[0035] The following discloses various embodiments or examples of the subject matter technical solutions. To simplify the disclosure, specific examples of the elements and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of protection of the present invention. For example, the distribution of the first feature and the second feature as described later in the specification can include an embodiment in which the first and second features are distributed in a direct connection, or an embodiment in which an additional feature is formed between the first and second features, so that the first and second features are not directly connected. In addition, reference numerals and / or letters may be repeated in different examples in these contents. This repetition is for brevity and clarity and does not in itself indicate the relationship between the various embodiments and / or structures to be discussed. Furthermore, when the first element is described in a manner connected or combined with the second element, the description includes embodiments in which the first and second elements are directly connected or combined with each other, as well as embodiments in which one or more other intervening elements are added to indirectly connect or combine the first and second elements with each other.

[0036] It is important to note that Figures 1 to 14 These are merely examples and are not drawn to scale, nor should they be construed as limiting the scope of protection of the present invention.

[0037] Figure 14 A comparative example heater 800 is shown, including a driver assembly 81, a heating element 82, and a frame 83. The driver assembly 81 has a first terminal 81a. The heating element 82 has a second terminal 82a. There is an electrical connection between the first terminal 81a and the second terminal 82a. The driver assembly 81 is attached to the frame 83, possibly by snap-fit. Both the first terminal 81a and the second terminal 82a are made of metal and are joined together by riveting after alignment.

[0038] The frame 83 has a first limiting wall 831 and a second limiting wall 832 disposed opposite to each other, and the heating element 82 is disposed between the first limiting wall 831 and the second limiting wall 832. For ease of assembly, the heating element 82 has gaps between itself and the first limiting wall 831 and the second limiting wall 832, which facilitates the assembly of the heating element 82 into the frame 83. These gaps can be referenced... Figure 12 The gaps G1 and G2 in the middle.

[0039] Due to the gap, the heating element 82 will wobble after being assembled into the frame 83, especially in the width direction of the heating element 82. This causes the second terminal 82a to easily deviate from the first terminal 81a before riveting, that is, the second terminal 82a is not aligned with the first terminal 81a.

[0040] To solve the above problems, the frame 83 has an elastic structure to support the heating element 82, thereby eliminating the influence of the gap and preventing the heating element 82 from swaying within the frame 83. The elastic structure can be as follows: Figure 14 The elastic sheet 832a shown is disposed on the second limiting wall 832. The heating element 82 compresses the elastic sheet 832a in the frame 83. The elastic force of the elastic sheet 832a positions the heating element 82 without it wobbling. In particular, the heating element 82 is positioned so that the second terminal 82a can be aligned with the first terminal 81a, which is the position that meets the riveting requirements.

[0041] However, there are limitations to using the elastic sheet 832a to position the heating element 82, namely, there are requirements regarding the size of the heating element 82. If the heating element 82 is too narrow, it will be unable to compress or compress the elastic sheet 832a sufficiently, thus failing to achieve the aforementioned positioning process or resulting in inaccurate positioning. Furthermore, setting the compression elastic sheet 832a on the frame 83 also complicates the structure of the heater 800.

[0042] To solve the above-mentioned technical problems, the present invention provides a heater assembly system 900.

[0043] like Figure 1 , 2 As shown in Figure 3, the heater assembly system 900 includes: a heater 2, including a driver assembly 21 and a heating element 22; the driver assembly 21 has a first terminal 21a; the heating element 22 has a second terminal 22a; the heater assembly system 900 also includes a clamp 3; the clamp 3 is used to clamp the heating element 22 so that the second terminal 22a is aligned with the first terminal 21a. Since the heating element 22 is positioned by clamping it with the clamp 3, adjusting or replacing the clamp 3 can accommodate heating elements 22 of different sizes, such as heating elements 22 of different widths, thereby simplifying the positioning of the heating element 22 and providing the advantage of precise positioning compared to the positioning method of elastic structures.

[0044] like Figure 2 , 10 As shown, the clamp 3 is configured to clamp the heating element 22 along the width direction WW. This allows the clamp 3 to have a smaller size.

[0045] like Figure 7 , 8 As shown in Figures 9, 10, 11, 12, 13A, and 13B, the heater 2 also includes a frame 23; the driver assembly 21 is connected to the frame 23; the frame 23 has a first limiting wall 231 and a second limiting wall 232; the clamp 3 has a first head 31 and a second head 32; as shown in Figures 9, 10, 11, 12, 13A, and 13B, the heater 2 further includes a frame 23; the driver assembly 21 is connected to the frame 23; the frame 23 has a first limiting wall 231 and a second limiting wall 232; the clamp 3 has a first head 31 and a second head 32; as shown in Figures 9, 10, 11, 12, 13A, and 13B, the heater 2 also includes a frame 23; the driver assembly 21 is connected to the Figure 11As shown, the heating element 22, the first head 31, and the second head 32 are all disposed between the first limiting wall 231 and the second limiting wall 232; wherein, the first head 31 and the second head 32 are used to clamp the heating element 22.

This design makes the clamp 3 compact. In an embodiment not shown, the first limiting wall 231 has a first through hole allowing the first intermediate portion 33 to pass through, and the second limiting wall 232 has a second through hole allowing the second intermediate portion 34 to pass through.

This design allows the first intermediate portion 33 and the second intermediate portion 34 to enter the first groove 231a and the second groove 232a respectively along the height direction of the heating element 22. The height direction of the heating element 22 is perpendicular to the width direction W and the length direction L.
