[0015] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0017] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of an electrode provided in an embodiment of the utility model.

[0018] As shown in the figure, in a specific embodiment, the electrode 10 provided by the utility model is an integrated structure, and its main part is made of a whole conductive body in the shape of a strip, which can be a copper body so that it has good bending performance. It is easy to be processed and formed by bending, stamping and other processes during the manufacturing process, and has good conductive performance when used.

[0019] The main body has a relatively thin thickness, and is formed with multiple groups of relative first accommodating parts 11 and second accommodating parts 12 by continuous bending. In the figure, a total of four groups of first accommodating parts 11 and second accommodating parts 12 are formed. The first accommodating part 11 is located at the top and is semicircular with an opening downward, and the second accommodating part 12 is located at the bottom and is semicircular with an opening upward. A circular accommodating cavity 13 is formed between each group of first accommodating parts 11 and second accommodating parts 12. Since there are a total of four groups of first accommodating parts 11 and second accommodating parts 12, a total of four accommodating cavities 13 are formed, which can accommodate four applicable objects at the same time, such as the four heating tubes described below.

[0020] Of course, in other embodiments, the first accommodating portion 11 and the second accommodating portion 12 may also be in other shapes according to different applicable objects. For example, if the cross section of the applicable object is rectangular, the first accommodating portion 11 may be in a U-shape with an opening downward, and the second accommodating portion 12 may be in a U-shape with an opening upward; if the cross section of the applicable object is hexagonal, the first accommodating portion 11 may be in a trapezoid with an opening downward, and the second accommodating portion 12 may be in a trapezoid with an opening upward, as long as the accommodating cavity 13 formed between the first accommodating portion 11 and the second accommodating portion 12 can be basically consistent with the cross-sectional shape of the applicable object, no further examples are given here.

[0021] A first connecting portion 14 is provided between adjacent first accommodating portions 11, and a second connecting portion 15 is provided between adjacent second accommodating portions 12. The first connecting portion 14 and the second connecting portion 15 are generally in a planar shape with a relatively narrow width, and smoothly transition with the first accommodating portion 11 and the second accommodating portion 12 respectively. The corresponding first connecting portion 14 and the second connecting portion 15 are used to connect with each other so that the first accommodating portion 11 and the second accommodating portion 12 can hold the applicable object tightly. One end of the main body is a lead-out end 16, and the other end is a closed end 17. The closed end 17 is closed and connected to the position where the lead-out end 16 is led outward.

[0022] Specifically, the lead-out end 16 of the main body is bent upward from the right side of the first connection part 11 located at the top, in a vertical state, and then led outward. The closed end 17 of the main body is located between the first connection part 14 and the second connection part 15 corresponding to the lead-out end 16 of the main body. The first connection part 14, the closed end 17, and the second connection part 15 are partially overlapped and then connected by screws 18 and nuts 19.

[0023] Of course, the first connection part 14 and the second connection part 15 can also be connected by welding, or a part of the first connection part 14 and the second connection part 15 are connected by screws 18 and nuts 19, and the other part of the first connection part 14 and the second connection part 15 are welded. In other words, the first connection part 14 and the second connection part 15 can be connected entirely by screws 18 and nuts 19, or entirely by welding, or by a combination of screws 18 and nuts 19 and welding.

[0024] It can be understood that the lead-out end 16 of the main body can be led outward from any first connection part 14 located at the top, or from any second connection part 15 located at the bottom, and can be adjusted according to the connection position of the electrode to better meet actual use requirements.

[0025] In other embodiments, the lead-out end 16 of the main body may also be led outward from one of the first accommodating portions 11 or the second accommodating portions 12 , and then the closed end 17 of the main body is connected to the root of the lead-out end 16 .

[0026] In this embodiment, the lead-out end 16 of the electrode is further provided with a connection buffer structure, which is a first recessed portion 161 . The first recessed portion 161 is substantially C-shaped, with its opening facing one side.

[0027] By designing a connection buffer structure, the lead end 16 of the electrode can have a certain elastic margin in the length direction, which can not only be adjusted as needed during use, but also, after the lead end 16 of the electrode is connected to the PCB board 26, it can effectively resist the influence of factors such as vibration, ensuring that the lead end 16 of the electrode is not easy to fall off.

[0028] In other embodiments, two or more connection buffer structures may be designed, or the connection buffer structure may be in a U-shape with an opening toward one side, or the connection buffer structure may be in an S-shape or a Z-shape, and so on.

[0029] In addition, each second receiving portion 12 of the electrode is also provided with a locking buffer structure having a second recessed portion 121 , which is generally in a U shape with its opening facing the interior of the receiving cavity 13 .

[0030] By designing a locking buffer structure, the second accommodating portion 12 can have a certain elastic margin. On the one hand, the accommodating cavity 13 between the first accommodating portion 11 and the second accommodating portion 12 can adapt to the heating tube whose diameter size varies within a certain range. On the other hand, when locking the electrode, the first accommodating portion 11 and the second accommodating portion 12 can be elastically clamped to the outer surface of the heating tube to avoid damage to the heating tube due to excessive clamping. Moreover, it can effectively resist the influence of factors such as vibration.

[0031] In other embodiments, a symmetrical locking buffer structure may be designed on the first accommodating portion 11, or two or more locking buffer structures may be designed on the same first accommodating portion 11 or the second accommodating portion 12, or the locking buffer structure may be in a C-shape with its opening facing the interior of the accommodating cavity 13, and so on.

[0032] Please refer to Figure 2 , Figure 3 , Figure 2 for Figure 1 The electrode usage status reference diagram shown; Figure 3 for Figure 2 A schematic structural diagram of the electrodes shown in FIG. 1 further connecting to a circuit board.

[0033] As shown in the figure, when it is necessary to power four parallel and spaced heating tubes 22, two integrated electrodes 10 introduced in this embodiment can be used and installed at both ends of the four heating tubes 22 to form the electrodes required at both ends.

[0034] When in use, the one-piece electrode 10 that has not been fixed can be unfolded from the opening of the main body and then snapped onto the ends of the four heating tubes 22, and then the first connecting part 14 and the second connecting part 15 can be fixedly connected by the connection method described above, so that the one-piece electrode 10 is locked on the four heating tubes 22 at the same time; the first connecting part 14 and the second connecting part 15 can also be fixedly connected in advance by the connection method described above, and then the one-piece electrode 10 can be simultaneously sleeved on the four heating tubes 22 from the ends of the heating tubes 22, and the accommodating cavity 13 can be tightened by using the above-mentioned locking buffer structure, so that the electrode is locked on the four heating tubes 22.

[0035] The lead end 16 of the electrode vertically extends upward for a distance and is electrically connected to the PCB board 26 to achieve the conductive function.

[0036] Of course, this embodiment only introduces the structure of the integrated electrode 10 by taking four heating tubes 22 as applicable objects. The number of accommodating cavities 13 of the integrated electrode 10 can be further increased or decreased as needed, and the integrated electrode 10 can also be applicable to other electronic components of different devices.

[0037] The above embodiments are only preferred solutions of the utility model, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementations. For example, along the arrangement direction of the accommodating cavity 13, the first accommodating portion 11 and the second accommodating portion 12 located on the side are also provided with corresponding first connecting portions 14 and second connecting portions 15 on the outside, and the lead-out terminal 16 of the main body is led out from the first connecting portion 14 or the second connecting portion 15, etc. Since there are many possible implementation methods, they will not be described one by one here.

[0038] Please refer to Figure 4 , Figure 5 , Figure 4 A schematic diagram of the overall structure of a heating device provided in an embodiment of the utility model; Figure 5 for Figure 4 Schematic diagram of the exploded structure of the heating device shown.

[0039] As shown in the figure, in addition to the above-mentioned integrated electrode, the utility model also provides a heating device, which can be a vehicle-use round tube heater 20.

[0040] The shell 21 of the heater 20 is usually provided with four parallel heating tubes 22, and the two ends of the heating tubes 22 are provided with collectors 23, and the two collectors 23 are respectively connected to the inlet pipe 24 and the outlet pipe 25. In the process of the medium flowing from the inlet pipe 24 into the heating tube 22 and then flowing out from the outlet pipe 25, the medium is heated to the required temperature by the heating tube 22. In order to supply power to each heating tube 22, electrodes need to be installed at both ends of the heating tube 22. Here, the integrated electrode 10 introduced above is used, and the integrated electrode 10 is clamped and locked to the heating tube 22, and its lead end 16 is electrically connected to the PCB board 26, and supplies power to the four heating tubes 22 at the same time.

[0041] Since the integrated electrode 10 at each end has only one lead-out terminal 16, the two integrated electrodes 10 have two lead-out terminals 16 in total, and the four heating tubes can be powered simultaneously through the two lead-out terminals 16, thereby greatly reducing the number of electrode lead-out terminals 16, and effectively solving the problem of difficult positioning of the electrode lead-out terminals 16 during assembly. The positioning accuracy of the electrode lead-out terminals 16 is relatively low, and there is no need to add an electrode conversion plate to integrate the electrode lead-out terminals 16, which reduces the types and quantities of parts, reduces manufacturing costs, and improves assembly efficiency.

[0042] The electrodes and heating devices provided by the present invention are introduced in detail above. The principle and implementation method of the present invention are described in detail using specific examples herein. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
