Description

Technical Field

[0001] This utility model belongs to the field of thick film heating core technology, and specifically relates to a busbar connection structure. Background Technology

[0002] The control side and water chamber side of the thick film heating core are located on the left and right sides of the middle shell, respectively. The control board on the control side needs to be connected to the thick film heating plate on the water chamber side.

[0003] The existing connection method involves a single busbar connection. The copper conductor in the busbar connects to the thick-film heating plate at one end and the control board at the other. This busbar connection method places high demands on the wiring and structural strength of the control board, resulting in high control board costs. It also requires high flatness of the thick-film heating plate and the flatness of the area where the control board is fixed in the middle shell, leading to high component costs, uncontrollable supplier materials, and difficulty in ensuring consistency and pass rates in the production process. Furthermore, this busbar connection method requires a relatively long exposed copper conductor within the busbar, demanding high straightness and perpendicularity, resulting in high manufacturing costs, inconvenient transportation, and susceptibility to damage. Finally, this method requires additional positioning posts on the middle shell, complicating the middle shell mold and making it difficult to guarantee precision, while also increasing the overall weight of the thick-film heating core. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a busbar connection structure.

[0005] Therefore, this utility model provides a busbar connection structure, including a thick film heating plate and a control plate that are parallel to each other. A first busbar perpendicular to the control plate and a second busbar parallel to the control plate are provided between the thick film heating plate and the control plate. A first copper conductor assembly is also provided inside the first busbar. The first copper conductor assembly passes through the interior of the first busbar and is led out. The end of the first copper conductor assembly is bent toward the high voltage positive and negative poles of the thick film heating plate.

[0006] The second busbar is provided with a second copper conductor assembly. The end of the second copper conductor assembly extends perpendicularly from the second busbar toward the control board and is inserted into the corresponding high voltage positive and negative terminals on the control board. The tail of the second copper conductor assembly extends from one side of the second busbar and is connected perpendicularly to the tail of the first copper conductor assembly.

[0007] Furthermore, a slot is provided at one end of the thick film heating plate, and a first busbar is connected to the slot; a locking member is provided on the first busbar, the locking member including two outwardly protruding extensions, and a slot is formed between the two extensions to clamp the thick film heating plate inside.

[0008] Furthermore, the tail of the second copper conductor assembly is provided with a through hole for the tail of the first copper conductor assembly to pass through, for connecting the first copper conductor assembly and the second copper conductor assembly.

[0009] Furthermore, the bending shape of the first copper conductor assembly enables the first busbar to be snapped onto the thick film heating plate via the extension, and the end of the first copper conductor assembly to be connected to the high voltage positive and negative poles of the thick film heating plate.

[0010] Furthermore, fixing holes are provided around the first and second busbars for subsequent installation.

[0011] This utility model provides a busbar connection structure, which has the following advantages:

[0012] 1. Simple structure, easy to assemble, and more suitable for automated production lines.

[0013] 2. The connection method of the busbar assembly can simplify the wiring of the control board and reduce the cost of the control board.

[0014] 3. The requirements for the flatness of the thick film heating plate and the flatness of the middle shell fixing control plate are relatively low. The supplier's incoming materials are controllable, which can ensure the consistency of parts and the qualification rate of finished products during the production process.

[0015] 4. The exposed copper conductors in the busbar assembly are of moderate length, making it easier to meet the requirements for straightness and perpendicularity, reducing manufacturing costs, facilitating transportation, and minimizing losses. Furthermore, under long-term durability and vibration conditions, it effectively reduces bending and breakage of the copper conductors.

[0016] 5. The connection method of the busbar assembly does not require the addition of additional positioning posts on the middle shell, which simplifies the structure, facilitates incoming material inspection, and reduces the overall weight of the thick film heating core.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] like Figure 1-3 As shown, this utility model provides a busbar connection structure, including a thick film heating plate 1 and a control plate 2 that are parallel to each other. A first busbar 3 perpendicular to the control plate 2 and a second busbar 4 parallel to the control plate 2 are disposed between the thick film heating plate 1 and the control plate 2. A slot 5 is opened at one end of the thick film heating plate 1, and the first busbar 3 is connected to the slot 5.

[0025] The first busbar 3 is provided with a locking member 6, which includes two outwardly protruding extensions 8 forming a groove between them to clamp the thick-film heating plate 1 inside, thus providing a limiting position. A first copper conductor assembly 9 is also provided inside the first busbar 3, extending through the interior of the first busbar 3 and leading out. The end of the first copper conductor assembly 9 is bent towards the high-voltage positive and negative electrodes of the thick-film heating plate 1. The bending shape of the first copper conductor assembly 9 allows the end of the first copper conductor assembly 9 to connect with the high-voltage positive and negative electrodes of the thick-film heating plate 1 after the first busbar 3 is locked onto the thick-film heating plate 1 via the extensions 8.

[0026] like Figure 4 As shown in Figure 5, a second copper conductor assembly 10 is disposed within the second busbar 4. The end of the second copper conductor assembly 10 extends perpendicularly from the second busbar 4 toward the control board 2 and is inserted into the corresponding high-voltage positive and negative ports on the control board 2, thereby limiting the movement of the control board 2. The tail of the second copper conductor assembly 10 extends from one side of the second busbar 4 and is connected perpendicularly to the tail of the first copper conductor assembly 9. The tail of the second copper conductor assembly 10 has a through hole for the tail of the first copper conductor assembly 9 to pass through, for welding the first copper conductor assembly 9 and the second copper conductor assembly 10 together.

[0027] By setting up the connection between the first busbar 3 and the second busbar 4, the connection length of the copper conductor between the thick-film heating plate 1 and the control board 2 is extended, reducing the position requirements of the high-voltage positive and negative terminals on the control board 2 and simplifying the wiring of the control board 2. Furthermore, the busbars can externally form insulation and protection for the copper conductor components, improving structural safety.

[0028] It should be noted that during the production of the first busbar 3 and the second busbar 4, the shape and orientation of the first copper conductor assembly 9 and the second copper conductor assembly 10 are designed according to the positions of the high voltage positive and negative terminals on the thick film heating plate 1 and the control plate 2. Then, the first copper conductor assembly 9 and the second copper conductor assembly 10 are placed into the corresponding molds and integrally formed by injection molding.

[0029] Fixing holes 7 are also provided around the first busbar 3 and the second busbar 4 for subsequent installation.

[0030] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
