Description

Technical Field

[0001] This application relates to the field of switch technology, specifically to a contactor. Background Technology

[0002] A contactor is a versatile switching device that uses electromagnetic, pneumatic, or hydraulic principles to quickly disconnect or connect the circuit connected to it.

[0003] A contactor comprises a base, an iron core, and a circuit board, with the iron core and circuit board typically housed within the base. In existing technology, to increase the magnetic force of the iron core for better engagement when the contactor is energized, the common approach is to increase the magnetic pole area of ​​the iron core. This increases the space occupied by the iron core within the base, consequently reducing the space available for the circuit board.

[0004] Therefore, there is an urgent need to propose a contactor to solve the problems existing in the current technology. Utility Model Content

[0005] This application provides a contactor to reduce the possibility that the base in the prior art cannot provide sufficient mounting space for the circuit board.

[0006] To achieve the above objectives, this application provides a contactor comprising a base, a cover, a first circuit board, a second circuit board, and an electrical connection assembly. The base has a first receiving cavity. The cover is disposed on the base and includes an upper cover having a second receiving cavity. The first circuit board is disposed within the first receiving cavity. The second circuit board is disposed within the second receiving cavity. One end of the electrical connection assembly is electrically connected to the first circuit board, and the other end is electrically connected to the second circuit board.

[0007] When adopting the above technical solution, the contactor provided in this application includes two circuit boards, namely a first circuit board and a second circuit board. The first circuit board is disposed within a first receiving cavity, and the second circuit board is disposed within a second receiving cavity. That is, the first circuit board is disposed within the base, and the second circuit board is disposed within the cover.

[0008] Compared to existing contactors that have only one circuit board, which is located inside the base, the contactor provided in this application has two circuit boards. This ensures sufficient circuit board area. Furthermore, the second circuit board is located inside the cover, which reduces the area of ​​the circuit board located inside the base. This further reduces the space occupied by the circuit board located inside the base and lowers the possibility that the base in the prior art cannot provide sufficient installation space for the circuit board.

[0009] In one possible implementation, the second receiving cavity has an opening. The electrical connection assembly includes a first electrical connector, one end of which is electrically connected to the second circuit board. The first electrical connector is disposed on the top cover and located at the opening end of the second receiving cavity. In a direction perpendicular to the second circuit board, the second receiving cavity has a first side cavity wall and a second side cavity wall disposed opposite each other, and the first electrical connector extends from the first side cavity wall to the side of the second side cavity wall away from the first side cavity wall.

[0010] When the above technical solution is adopted, the first electrical connector is located at the opening end of the second receiving cavity, and in the direction perpendicular to the second circuit board, the second receiving cavity has a first side cavity wall and a second side cavity wall disposed opposite to each other. The first electrical connector extends from the first side cavity wall to the side of the second side cavity wall away from the first side cavity wall, so that the first electrical connector spans across the opening end of the second receiving cavity.

[0011] Thus, when the first electrical connector is electrically connected to the second circuit board, the first electrical connector can block and limit the second circuit board, reducing the possibility of the second circuit board sliding out of the second receiving cavity.

[0012] In one possible implementation, two first limiting bosses are provided on the first side cavity wall, protruding into the second receiving cavity. The two first limiting bosses are arranged opposite to each other, forming a first limiting space between them. One end of the first electrical connector is interference-fitted into the first limiting space.

[0013] When the above technical solution is adopted, the surfaces of the two first limiting bosses near the first limiting space are tightly fitted with the two opposing surfaces of the first electrical connector, so that the first electrical connector is interference-fitted with the upper cover. The first electrical connector is subjected to relatively uniform force, which can avoid stress concentration.

[0014] Meanwhile, the first electrical connector is connected to the two opposing first limiting bosses through their dimensional fit. During installation, simply inserting one end of the first electrical connector into the first limiting space is sufficient to connect one end of the first electrical connector to the top cover, eliminating the need for bolts, rivets, etc. This one-step connection simplifies the structure and reduces assembly steps.

[0015] Furthermore, the first electrical connector is interference-fitted with the top cover, allowing for disassembly under certain conditions to repair or replace both the first electrical connector and the top cover separately, thereby reducing maintenance costs.

[0016] In one possible implementation, a first slot is provided on the second side cavity wall, and the opening direction of the first slot is the same as the opening direction of the second receiving cavity. The first electrical connector includes a first body and a first latch, the first body extending from the first side cavity wall to the side of the second side cavity wall away from the first side cavity wall, and the first body is electrically connected to the second circuit board. The first latch extends into the first slot and is secured to the side wall of the first slot.

[0017] When the above technical solution is adopted, the first buckle extends into the first slot and is fastened to the side wall of the first slot, thereby making the first buckle fastened to the first slot.

[0018] During installation, simply insert the first clip into the first slot to connect the first clip to the top cover, thereby connecting the first electrical connector to the top cover. No bolts or rivets are needed, allowing for a one-step installation that simplifies the structure and reduces assembly steps.

[0019] Meanwhile, the first buckle is locked in the first slot, and can be disassembled under certain conditions to repair or replace the first electrical connector and the top cover, thereby reducing maintenance costs.

[0020] In one possible implementation, two opposing first limiting posts are disposed within the second receiving cavity. Each first limiting post has a first end and a second end disposed opposite to each other, with the first end disposed on the bottom cavity wall of the second receiving cavity. A second limiting space is formed between the two first limiting posts, and the second circuit board is inserted into the second limiting space.

[0021] When using the above technical solution, during specific installation, the second circuit board can be installed simply by inserting it into the second limiting space. There is no need to use bolts, rivets, etc., which can be done in one step, simplifying the structure and reducing assembly steps.

[0022] Meanwhile, the second circuit board is inserted into the second limiting space, and can be disassembled under certain conditions to repair or replace the second circuit board and the top cover respectively, which can reduce maintenance costs.

[0023] In addition, the first electrical connector and the first limiting post can limit the second circuit board, which can enhance the stability of the second circuit board on the top cover.

[0024] In one possible implementation, at least one first limiting post is provided with a first guide surface on the side near the other first limiting post, and the first guide surface is provided at the second end; the first guide surface is inclined towards the second limiting space along the direction from the second end to the first end.

[0025] When the above technical solution is adopted, during the process of inserting the second circuit board into the second limiting space, the first guide surface serves two purposes: firstly, it guides the second circuit board to be inserted between the two first limiting posts, facilitating the installation of the second circuit board; secondly, it prevents the second end from scratching the second circuit board, thus avoiding damage to the second circuit board.

[0026] In one possible implementation, the electrical connection assembly further includes a second electrical connector. One end of the second electrical connector is electrically connected to the other end of the first electrical connector, and the end of the first electrical connector used for electrical connection with the second electrical connector is provided with a first bend, which is used for elastic contact with one end of the second electrical connector.

[0027] When adopting the above technical solution, the electrical connection assembly includes a first electrical connector and a second electrical connector. With the positions of the first circuit board and the second circuit board relatively fixed, the second electrical connector can shorten the length of the first electrical connector. When the first electrical connector is damaged and needs to be replaced, the amount of material used can be reduced, helping to save costs.

[0028] The first electrical connector has a first bend at one end for electrical connection with the second electrical connector, and the first bend is for elastic contact with one end of the second electrical connector. When the first electrical connector is electrically connected to the second electrical connector, the first bend has a force that moves closer to the second electrical connector, which can improve the reliability of the electrical connection between the first electrical connector and the second electrical connector.

[0029] Meanwhile, the first electrical connector and the second electrical connector are detachable, which facilitates the repair or replacement of the first electrical connector and the second electrical connector respectively, thereby reducing maintenance costs.

[0030] In one possible implementation, the electrical connection assembly further includes a third electrical connector. One end of the third electrical connector is electrically connected to the other end of the second electrical connector. The end of the third electrical connector used for electrical connection with the second electrical connector is provided with two opposing second limiting posts, forming a third limiting space between the two second limiting posts. The end of the second electrical connector used for electrical connection with the third electrical connector is interference-fitted into the third limiting space.

[0031] When adopting the above technical solution, the electrical connection assembly includes a first electrical connector, a second electrical connector, and a third electrical connector. With the positions between the first and second circuit boards relatively fixed, the third electrical connector can shorten the length of the second electrical connector. When the second electrical connector is damaged and needs replacement, the amount of material used can be reduced, helping to save costs.

[0032] The second and third electrical connectors are plugged into each other, allowing for quick and convenient connection and disconnection. Furthermore, when either the second or third electrical connector is damaged and requires replacement or repair, it is easy to separate them for individual repair or replacement, thus reducing maintenance costs.

[0033] In one possible implementation, the electrical connection assembly further includes a fourth electrical connector. The fourth electrical connector is disposed on the base, and its two ends are electrically connected to the third electrical connector and the first circuit board, respectively. The end of the third electrical connector used for electrical connection with the fourth electrical connector is provided with two opposing third limiting posts, forming a fourth limiting space between the two third limiting posts, and one end of the fourth electrical connector is interference-fitted into the fourth limiting space.

[0034] When adopting the above technical solution, the electrical connection assembly includes a first electrical connector, a second electrical connector, a third electrical connector, and a fourth electrical connector. With the positions between the first and second circuit boards relatively fixed, providing a fourth electrical connector can shorten the length of the third electrical connector. When the third electrical connector is damaged and needs replacement, the amount of material used can be reduced, helping to save costs.

[0035] The third and fourth electrical connectors are plugged into each other, allowing for quick and convenient connection and disconnection. Furthermore, when either the third or fourth electrical connector is damaged and requires replacement or repair, it is easy to separate them for individual repair or replacement, thus reducing maintenance costs.

[0036] In one possible implementation, a mounting bracket is provided on the base, the mounting bracket having a third receiving cavity with one end open, the opening of the third receiving cavity facing the cover. The end of the third electrical connector for electrical connection with the fourth electrical connector is located in the third receiving cavity, and the end of the fourth electrical connector for electrical connection with the third electrical connector is located in the third receiving cavity.

[0037] In a direction perpendicular to the direction from one of the third limiting posts to the other, the two opposite side walls of the mounting bracket are respectively provided with through holes and limiting holes, and the fourth electrical connector is provided with a fourth limiting post that mates with the limiting holes.

[0038] The mounting bracket is also provided with a clearance hole, which is connected to the through hole, so that one end of the fourth electrical connector can extend into the third receiving cavity from the clearance hole and the through hole, and the fourth limiting post can extend into the limiting hole.

[0039] When adopting the above technical solution, the end of the third electrical connector used for electrical connection with the fourth electrical connector can extend into the third receiving cavity from the open end of the third receiving cavity. The end of the fourth electrical connector used for electrical connection with the third electrical connector can extend into the third receiving cavity through the clearance hole and the through hole, and the end of the fourth electrical connector is interference-fitted into the fourth limiting space, so that the third electrical connector and the fourth electrical connector are electrically connected. At the same time, the fourth limiting post extends into the limiting hole, which can enhance the firmness of the fourth electrical connector on the base. Attached Figure Description

[0060] Please refer to Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a contactor, which includes a base 1, a cover 2, a first circuit board 3, a second circuit board 4, and an electrical connection assembly 5. The base 1 has a first receiving cavity. The cover 2 covers the base 1 and includes an upper cover 21 with a second receiving cavity having an opening. The first circuit board 3 is disposed within the first receiving cavity. The second circuit board 4 is disposed within the second receiving cavity.

[0061] In fact, the cover 2 includes a base 22 and an upper cover 21. The base 22 has a receiving cavity with an opening at one end, and the opening of the base 22 is set towards the base 1.

[0062] The top cover 21 is located on the side of the base 22 away from the base 1. Figure 1 Taking the placement of the contactor as an example, the top cover 21 is located on top of the base 22.

[0063] The top cover 21 has a second receiving cavity with an opening at one end, and the opening of the second receiving cavity is disposed facing one side of the outer wall of the cover body 22.

[0064] The size of the second receiving cavity is not specifically limited here. The second receiving cavity can be a polygonal prism structure; in the embodiments provided in this application, the second receiving cavity is a cuboid structure.

[0065] The top cover 21 cooperates with the base 22 to block the opening of the second receiving cavity so that the second circuit board 4 is placed in a closed environment.

[0066] The connection method between the top cover 21 and the base 22 is not limited here.

[0067] For example, the top cover 21 and the base 22 can be connected by welding, snap-fitting or other means.

[0068] In the embodiments provided in this application, the base 22 has an installation space at its top, and the upper cover 21 is disposed within the installation space. Meanwhile, referring to... Figures 3 to 5 As shown, a protrusion 214 is provided on the outer wall of the upper cover 21 so that the upper cover 21 and the base 22 are interference fit, thereby enhancing the stability of the upper cover 21 on the base 22.

[0069] The base 1 has a first receiving cavity, and one end of the first receiving cavity is an open end, that is, the base 1 has a first receiving cavity with one end open.

[0070] In practice, the top cover 21 is mounted on the base 22. The opening of the first receiving cavity of the base 1 can be set to face the base 22, and the opening of the receiving cavity of the base 22 can be set to face the base 1, so that the cover 2 can be placed on the base 1.

[0071] The connection method between the base 1 and the cover 2 is not specifically limited here. For example, the connection method between the base 1 and the cover 2 can be snap-fit, welding, or screw connection, etc.

[0072] The base 1 and the cover 2 are matched to form the housing of the contactor provided in this application embodiment. The first circuit board 3 and the second circuit board 4 are both disposed inside the housing.

[0073] The housing can accommodate the first circuit board 3 and the second circuit board 4, providing a stable space for the first circuit board 3, the second circuit board 4, and other components disposed within the housing, ensuring that they can work normally without external interference.

[0074] Meanwhile, the housing can provide positioning and support for the first circuit board 3 and the second circuit board 4, preventing the components installed inside the housing from shifting or being damaged during operation. The housing can also withstand a certain amount of external pressure, protecting the first circuit board 3 and the second circuit board 4 from damage.

[0075] In addition, the housing has a protective function, which can prevent moisture, dust, dirt and other impurities from the outside of the housing from entering the inside of the housing, thereby avoiding corrosion or damage to components such as the first circuit board 3 and the second circuit board 4 installed inside the housing.

[0076] The method by which the first circuit board 3 is disposed within the first receiving cavity is not specifically limited here. For example, the first circuit board 3 can be disposed within the first receiving cavity by means of snap-fitting, bonding, etc., but of course, it is not limited to these methods in practice.

[0077] The method by which the second circuit board 4 is disposed within the second receiving cavity is not specifically limited here. For example, the second circuit board 4 can be disposed within the second receiving cavity by means of snap-fitting, bonding, etc., but of course, it is not limited to this.

[0078] The contactor provided in this embodiment includes two circuit boards, namely a first circuit board 3 and a second circuit board 4. The first circuit board 3 is disposed in a first receiving cavity, and the second circuit board 4 is disposed in a second receiving cavity. That is, the first circuit board 3 is disposed in the base 1, and the second circuit board 4 is disposed in the cover 2.

[0079] Compared to existing contactors that have only one circuit board, which is housed within the base 1, the contactor provided in this embodiment has two circuit boards, ensuring sufficient area for the circuit boards. Furthermore, the second circuit board 4 is housed within the cover 2, reducing the area of ​​the circuit board housed within the base 1. This further reduces the space occupied by the circuit board within the base 1, mitigating the possibility that the base 1 in existing technologies may not provide sufficient mounting space for the circuit board.

[0080] One end of the electrical connection component 5 is electrically connected to the first circuit board 3, and the other end is electrically connected to the second circuit board 4, thereby making the first circuit board 3 and the second circuit board 4 electrically connected.

[0081] The structural form of the electrical connection component 5 is not specifically limited here. For example, the electrical connection component 5 can be a wire or a conductive sheet, etc.

[0082] The connection method between the first circuit board 3, the second circuit board 4 and the electrical connection component 5 is not limited here, and the specific method shall be subject to the actual situation.

[0083] It should be noted that the contactor core provided in this application embodiment can be a combination of T-shaped core and U-shaped core, but it is not limited to this in practice.

[0084] In one possible implementation, such as Figures 2 to 5 As shown, the electrical connection assembly 5 includes a first electrical connector 51, one end of which is electrically connected to the second circuit board 4.

[0085] The first electrical connector 51 can be a plate-like structure. The first electrical connector 51 can be soldered to the second circuit board 4, but in practice it is not limited to this.

[0086] The first electrical connector 51 is disposed on the upper cover 21. In specific implementation, the first electrical connector 51 can be fixedly connected to the upper cover 21 by riveting or gluing.

[0087] The first electrical connector 51 is located at the opening end of the second receiving cavity, and in a direction perpendicular to the second circuit board 4, the second receiving cavity has a first side cavity wall and a second side cavity wall disposed opposite to each other. The first electrical connector 51 extends from the first side cavity wall to the side of the second side cavity wall away from the first side cavity wall, such that the first electrical connector 51 spans across the opening end of the second receiving cavity.

[0088] Thus, when the first electrical connector 51 is electrically connected to the second circuit board 4, the first electrical connector 51 can block and limit the second circuit board 4, reducing the possibility of the second circuit board 4 sliding out of the second receiving cavity.

[0089] It should be noted that when the electrical connection assembly 5 includes the first electrical connector 51, one end of the first electrical connector 51 is electrically connected to the second circuit board 4, and the other end of the first electrical connector 51 can be directly or indirectly electrically connected to the first circuit board 3.

[0090] In practice, the first electrical connector 51 can be soldered to the first circuit board 3, but in reality, it is not limited to this.

[0091] When there are two electrical connection assemblies 5, there are two first electrical connectors 51, and the two first electrical connectors 51 are arranged in parallel, such as... Figure 4 As shown.

[0092] Additionally, it should be noted that, in specific implementation, the opening direction of the second receiving cavity is not specifically limited here. The opening direction of the second receiving cavity can be perpendicular to the opening direction of the first receiving cavity.

[0093] by Figure 1 Taking the placement of the contactor as an example, the opening direction of the first receiving cavity is vertical, and the opening direction of the second receiving cavity is horizontal.

[0094] As one possible approach, such as Figure 5 As shown, two first limiting protrusions 211 are provided on the first side cavity wall. The first limiting protrusions 211 protrude into the second receiving cavity. The two first limiting protrusions 211 are arranged opposite to each other and are parallel. A first limiting space is formed between the two first limiting protrusions 211.

[0095] like Figure 4 As shown, one end of the first electrical connector 51 is interference-fitted into the first limiting space.

[0096] Thus, the surfaces of the two first limiting protrusions 211 near the first limiting space are tightly fitted with the two opposing surfaces of the first electrical connector 51, resulting in an interference fit between the first electrical connector 51 and the upper cover 21. The first electrical connector 51 is subjected to relatively uniform force, which can avoid stress concentration.

[0097] Meanwhile, the first electrical connector 51 is connected to the two opposing first limiting bosses 211 through their own dimensional fit. In actual installation, one end of the first electrical connector 51 only needs to be inserted into the first limiting space to connect one end of the first electrical connector 51 to the upper cover 21. There is no need to use bolts, rivets, etc., which can be done in one step, simplifying the structure and reducing assembly steps.

[0098] Furthermore, the first electrical connector 51 is interference-fitted with the upper cover 21, and can be disassembled under certain conditions to repair or replace the first electrical connector 51 and the upper cover 21 respectively, which can reduce maintenance costs.

[0099] Combination Figures 4 to 6 As shown, the first electrical connector 51 includes a first body 511 and a first latch 512 connected together. The first body 511 extends from the first side cavity wall to the side of the second side cavity wall away from the first side cavity wall. The first body 511 is electrically connected to the second circuit board 4.

[0100] Meanwhile, a second bend 514 is provided at one end of the first body 511 near the first side cavity wall, and one end of the second bend 514 extends toward the second receiving cavity.

[0101] In practice, the second bend 514 is interference-fitted with the two oppositely arranged first limiting bosses 211.

[0102] When there are two electrical connection components 5, there are four first limiting bosses 211, two of which are arranged opposite each other, and the other two are arranged opposite each other. The two oppositely arranged first limiting bosses 211 correspond to the second bend 514 of one first electrical connection 51.

[0103] In some embodiments, such as Figure 5 As shown, a first slot 212 is provided on the second side cavity wall, and the opening direction of the first slot 212 is the same as the opening direction of the second receiving cavity.

[0104] like Figure 4 As shown, the first buckle 512 extends into the first slot 212 and is fastened to the side wall of the first slot 212.

[0105] Thus, the first buckle 512 extends into the first slot 212 and is fastened to the side wall of the first slot 212, thereby making the first buckle 512 fastened in the first slot 212.

[0106] During installation, simply insert the first buckle 512 into the first slot 212 to connect the first buckle 512 to the top cover 21, thereby connecting the first electrical connector 51 to the top cover 21. No bolts or rivets are required, which can be done in one step, simplifying the structure and reducing assembly steps.

[0107] Meanwhile, the first buckle 512 is locked in the first slot 212, and can be disassembled under certain conditions to repair or replace the first electrical connector 51 and the top cover 21, thereby reducing maintenance costs.

[0108] In addition, the second bend 514 and the first buckle 512 of the first electrical connector 51 are both connected to the upper cover 21, which can enhance the stability of the first electrical connector 51 on the upper cover 21.

[0109] Understandably, the first latch 512 is elastic. Under a certain external force, the end of the first latch 512 that is away from the first body 511 can swing relative to the first body 511.

[0110] The shape and size of the first slot 212 are not specifically limited here, and shall be subject to the actual situation.

[0111] Accordingly, when there are two electrical connection components 5, there are two first slots 212.

[0112] In some embodiments, please refer to Figure 5 The second receiving cavity is provided with two opposing first limiting posts 213. The first limiting posts 213 have a first end and a second end that are opposite to each other. The first end is located on the bottom cavity wall of the second receiving cavity, that is, the first end is located at the end of the second receiving cavity away from the opening.

[0113] It should be noted that the bottom cavity wall of the second receiving cavity refers to the side cavity wall of the second receiving cavity away from the opening.

[0114] Combination Figure 4 and Figure 5 A second limiting space is formed between the two first limiting posts 213, and the second circuit board 4 is inserted into the second limiting space.

[0115] During installation, the second circuit board 4 can be installed simply by inserting it into the second limiting space. No bolts or rivets are required, and the installation can be completed in one step, which simplifies the structure and reduces assembly steps.

[0116] Meanwhile, the second circuit board 4 is inserted into the second limiting space and can be disassembled under certain conditions to repair or replace the second circuit board 4 and the top cover 21 respectively, which can reduce maintenance costs.

[0117] In addition, the first electrical connector 51 and the first limiting post 213 can limit the second circuit board 4, which can enhance the stability of the second circuit board 4 on the upper cover 21.

[0118] To enhance the stability of the second circuit board 4 within the second receiving cavity, two pairs of opposing first limiting posts 213 can be provided. These two pairs of opposing first limiting posts 213 can be respectively provided at both ends of the length direction of the second circuit board 4.

[0119] Additionally, it should be noted that the top cover 21 provided in this application embodiment can be an integral structure, that is, when the top cover body is processed, the first limiting boss 211, the first limiting post 213 and the first slot 212 are formed together.

[0120] As an optional approach, such as Figure 5As shown, at least one first limiting post 213 has a first guide surface 2131 on the side near the other first limiting post 213, and the first guide surface 2131 is located at the second end. Along the direction from the second end to the first end, the first guide surface 2131 is inclined toward the second limiting space, making the side of the second limiting space near the opening end of the second receiving cavity larger.

[0121] In this case, during the process of inserting the second circuit board 4 into the second limiting space, the first guide surface 2131 serves two purposes: firstly, it guides the second circuit board 4 to be inserted between the two first limiting posts 213, facilitating the installation of the second circuit board 4; secondly, it prevents the second end from scratching the second circuit board 4, thus avoiding damage to the second circuit board 4.

[0122] In practice, a first guide surface 2131 can be provided on each first limit post 213, but no specific limitation is made here.

[0123] In one alternative approach, combining Figure 2 , Figure 3 and Figure 6 The electrical connection assembly 5 provided in this application embodiment further includes a second electrical connector 52. One end of the second electrical connector 52 is electrically connected to the other end of the first electrical connector 51. The end of the first electrical connector 51 used for electrical connection with the second electrical connector 52 is provided with a first bending portion 513, which is used for elastic contact with one end of the second electrical connector 52.

[0124] At this time, the electrical connection assembly 5 includes a first electrical connector 51 and a second electrical connector 52. With the positions between the first circuit board 3 and the second circuit board 4 relatively fixed, the second electrical connector 52 can shorten the length of the first electrical connector 51. When the first electrical connector 51 is damaged and needs to be replaced, the amount of material used can be reduced, helping to save costs.

[0125] The first electrical connector 51 has a first bend 513 at one end for electrical connection with the second electrical connector 52. The first bend 513 is for elastic contact with one end of the second electrical connector 52. When the first electrical connector 51 and the second electrical connector 52 are electrically connected, the first bend 513 has a force that moves closer to the second electrical connector 52, which can improve the reliability of the electrical connection between the first electrical connector 51 and the second electrical connector 52.

[0126] Meanwhile, the first electrical connector 51 and the second electrical connector 52 are detachable, which facilitates the repair or replacement of the first electrical connector 51 and the second electrical connector 52 respectively, thereby reducing maintenance costs.

[0127] It should be noted that when the electrical connection assembly 5 includes a first electrical connector 51 and a second electrical connector 52, one end of the first electrical connector 51 is electrically connected to the second circuit board 4, the other end of the first electrical connector 51 is electrically connected to the second electrical connector 52, and the other end of the second electrical connector 52 can be directly or indirectly electrically connected to the first circuit board 3, thereby realizing the electrical connection between the first circuit board 3 and the second circuit board 4.

[0128] In practice, the second electrical connector 52 can be directly or indirectly soldered to the first circuit board 3, but in practice it is not limited to this.

[0129] The second electrical connector 52 can be fixedly installed on the base 22 to enhance the stability of the second electrical connector 52 and ensure the reliability of the electrical connection between the first electrical connector 51 and the second electrical connector 52.

[0130] In addition, it should be noted that the first body 511, the first buckle 512, the first bending part 513 and the second bending part 514 can be set separately. At the installation site, the first buckle 512, the first bending part 513 and the second bending part 514 can be set on the first body 511 by welding or riveting.

[0131] In the embodiments provided in this application, the first body 511, the first buckle 512, the first bent portion 513 and the second bent portion 514 can be processed together during processing.

[0132] In this way, stress concentration problems caused by welding or riveting can be avoided, higher dimensional accuracy and consistency can be guaranteed, the structural strength of the first electrical connector 51 can be improved, and there is no need to cut the first electrical connector 51, reducing material usage and avoiding material waste.

[0133] Furthermore, the integrated structure reduces connection points, lowering the risk of failure due to loose connections, corrosion, or fatigue, and improving fatigue resistance. Additionally, it reduces the number of parts and the assembly steps of the first electrical connector 51, simplifying the operation process.

[0134] The materials of the first electrical connector 51 and the second electrical connector 52 are not specifically limited here, but shall be subject to the actual situation. The structure of the second electrical connector 52 is also not specifically limited here.

[0135] In one example, combining Figure 2 , Figure 3 and Figure 6 The electrical connection assembly 5 provided in this application embodiment further includes a third electrical connector 53. One end of the third electrical connector 53 is electrically connected to the other end of the second electrical connector 52.

[0136] At this time, the electrical connection assembly 5 includes a first electrical connector 51, a second electrical connector 52, and a third electrical connector 53. With the positions between the first circuit board 3 and the second circuit board 4 relatively fixed, the third electrical connector 53 can shorten the length of the second electrical connector 52. When the second electrical connector 52 is damaged and needs to be replaced, the amount of material used can be reduced, helping to save costs.

[0137] It should be noted that when the electrical connection assembly 5 includes a first electrical connector 51, a second electrical connector 52, and a third electrical connector 53, one end of the first electrical connector 51 is electrically connected to the second circuit board 4, the other end of the first electrical connector 51 is electrically connected to one end of the second electrical connector 52, one end of the third electrical connector 53 is electrically connected to the other end of the second electrical connector 52, and the other end of the third electrical connector 53 can be directly or indirectly electrically connected to the first circuit board 3, thereby realizing the electrical connection between the first circuit board 3 and the second circuit board 4.

[0138] In practice, the third electrical connector 53 can be directly or indirectly soldered to the first circuit board 3, but in practice it is not limited to this.

[0139] Moreover, combined Figure 6 and Figure 7 As shown, the third electrical connector 53 has two opposing second limiting posts 531 at one end for electrical connection with the second electrical connector 52, forming a third limiting space between the two second limiting posts 531. The end of the second electrical connector 52 for electrical connection with the third electrical connector 53 is interference-fitted into the third limiting space.

[0140] Thus, the second electrical connector 52 and the third electrical connector 53 are plugged into each other, allowing for quick and convenient connection and disconnection. Furthermore, the second electrical connector 52 and the third electrical connector 53 are detachable. When either the second electrical connector 52 or the third electrical connector 53 is damaged and needs replacement or repair, it is easy to separate the two connectors for separate repair or replacement, thereby reducing maintenance costs.

[0141] Combination Figure 6 and Figure 7 As shown, one of the second limiting posts 531 has a first protrusion 5311 and a first recess 5312 alternately arranged on the side facing the third limiting space, and the other second limiting post 531 has a second protrusion 5313 and a second recess 5314 alternately arranged on the side facing the third limiting space.

[0142] When the end of the second electrical connector 52 used for electrical connection with the third electrical connector 53 is interference-fitted into the third limiting space, the first protrusion 5311 and the second protrusion 5313 respectively contact the two opposing surfaces of the second electrical connector 52.

[0143] This increases the contact area between the second electrical connector 52 and the third electrical connector 53, improves the stability of their contact, and reduces the contact resistance.

[0144] In another example, combining Figure 2 , Figure 3 and Figure 6 The electrical connection component 5 provided in this application embodiment further includes a fourth electrical connector 54, the two ends of which are electrically connected to the third electrical connector 53 and the first circuit board 3, respectively.

[0145] At this time, the electrical connection assembly 5 includes a first electrical connector 51, a second electrical connector 52, a third electrical connector 53, and a fourth electrical connector 54. With the positions between the first circuit board 3 and the second circuit board 4 relatively fixed, the fourth electrical connector 54 can shorten the length of the third electrical connector 53. When the third electrical connector 53 is damaged and needs to be replaced, the amount of material used can be reduced, helping to save costs.

[0146] It should be noted that, in the embodiments provided in this application, the electrical connection component 5 is also electrically connected to the control power supply to supply power to the first circuit board 3 and the second circuit board 4, and the number of electrical connection components 5 is generally two.

[0147] In practice, the control power supply is electrically connected to the second electrical connector 52, and the control power supply is electrically connected to the second circuit board 4 via the first electrical connector 51 and the second electrical connector 52. The control power supply is also electrically connected to the first circuit board 3 via the second electrical connector 52, the third electrical connector 53, and the fourth electrical connector 54.

[0148] like Figures 6 to 8 As shown, the third electrical connector 53 is provided with two oppositely arranged third limiting posts 532 at one end for electrical connection with the fourth electrical connector 54, and a fourth limiting space is formed between the two third limiting posts 532. One end of the fourth electrical connector 54 is interference-fitted into the fourth limiting space.

[0149] Thus, the third electrical connector 53 and the fourth electrical connector 54 can be plugged into each other, enabling quick and convenient connection and disconnection. Furthermore, when either the third electrical connector 53 or the fourth electrical connector 54 is damaged and needs replacement or repair, it is easy to separate the three electrical connectors 53 and 54 for separate repair or replacement, thereby reducing maintenance costs.

[0150] Combination Figure 6 and Figure 7 As shown, each of the third limiting posts 532 has a third protrusion 5321 on the side facing the fourth limiting space.

[0151] When the end of the fourth electrical connector 54 used for electrical connection with the third electrical connector 53 is interference-fitted into the fourth limiting space, the two third protrusions 5321 respectively contact the two opposing surfaces of the fourth electrical connector 54.

[0152] This increases the contact area between the fourth electrical connector 54 and the third electrical connector 53, improves the stability of their contact, and reduces the contact resistance.

[0153] It should be noted that the specific structures of the first electrical connector 51, the second electrical connector 52, the third electrical connector 53, and the fourth electrical connector 54 provided in the embodiments of this application are not specifically limited here, and the actual situation shall prevail.

[0154] In some embodiments, the fourth electrical connector 54 is disposed on the base 1, and the fourth electrical connector 54 may be disposed on the base 1 indirectly or directly. The manner in which the fourth electrical connector 54 is disposed on the base 1 is not specifically limited here.

[0155] Combination Figure 2 and Figure 8 As shown, a mounting bracket 11 is provided on the base 1. The mounting bracket 11 has a third receiving cavity with an opening at one end, and the opening of the third receiving cavity is oriented towards the cover 2.

[0156] In fact, the base 1 is provided with a coil frame for carrying the coil, and the mounting bracket 11 is set on the coil frame.

[0157] The end of the third electrical connector 53 that is electrically connected to the fourth electrical connector 54 is located inside the third receiving cavity, and the end of the fourth electrical connector 54 that is electrically connected to the third electrical connector 53 is located inside the third receiving cavity. That is, the connection position of the third electrical connector 53 and the fourth electrical connector 54 is located inside the third receiving cavity.

[0158] In a direction perpendicular to the direction from one of the third limiting posts 532 to the other, the two oppositely arranged side walls of the mounting bracket 11 are respectively provided with through holes 111 and limiting holes, and the fourth electrical connector 54 is provided with a fourth limiting post that cooperates with the limiting hole.

[0159] The mounting bracket 11 is also provided with a clearance hole 112, which is connected to the through hole 111. This allows one end of the fourth electrical connector 54 to extend into the third receiving cavity from the clearance hole 112 and the through hole 111, and allows the fourth limiting post to extend into the limiting hole.

[0160] In a specific implementation, the end of the third electrical connector 53 that is electrically connected to the fourth electrical connector 54 can extend into the third receiving cavity from the open end of the third receiving cavity. The end of the fourth electrical connector 54 that is electrically connected to the third electrical connector 53 can extend into the third receiving cavity through the clearance hole 112 and the through hole 111, and the end of the fourth electrical connector 54 is interference-fitted into the fourth limiting space, so that the third electrical connector 53 and the fourth electrical connector 54 are electrically connected.

[0161] At the same time, the fourth limiting post extends into the limiting hole, which can enhance the firmness of the fourth electrical connector 54 on the base 1.

[0162] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by fasteners, such as a connection fixed by screws, bolts, or other spacers; a physical connection can also be a detachable connection, such as a snap-fit ​​or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
