Electrical control devices generally consist of three main modules: a control module, a power supply module, and a communication module. In related technologies, multiple modules are typically connected via wires. This wiring process involves multiple steps, including cutting, stripping, soldering, and securing the wires, making the wiring of HVAC electrical control devices quite complex. Utility Model Content

[0023] In some embodiments, the insulating base is provided with a mounting structure that is adapted to the installation environment to fix the insulating base within the housing.
[0024] Secondly, embodiments of this application provide an electronic control device, comprising:
[0025] case;
[0026] Both the first circuit module and the second circuit module are housed within the casing;
[0027] In any of the above embodiments, the connector has two electrical contact protrusions connected to the first circuit module and the second circuit module respectively, so as to electrically connect the first circuit module and the second circuit module.
[0028] In some embodiments, the housing is provided with a first cavity and a second cavity, the first cavity and the second cavity being disposed at a distance from each other in the thickness direction of the housing, wherein the portion of the housing located between the first cavity and the second cavity is provided with a first opening, the first opening communicating with the first cavity and the second cavity;
[0029] A first circuit module and a second circuit module are disposed in a first cavity.
[0030] Both the insulating base and the electrical terminal are installed through the first opening.
[0031] In some embodiments, the housing includes a heat dissipation structure, a first cover, and a second cover. The first cover cooperates with the heat dissipation structure to form a first cavity, and the second cover cooperates with the heat dissipation structure to form a second cavity.
[0032] The heat dissipation structure has a first side and a second side, with the first cavity and the second cavity located on the first side and the second side of the heat dissipation structure, respectively, and the heat dissipation structure is provided with a first opening.
[0033] In some embodiments, the insulating base includes a base body and a limiting part and a latching part respectively connected to the base body. The power supply post passes through the base body, the limiting part protrudes from the outer wall surface of the base body, and the latching part and the limiting part are spaced apart along the depth direction of the first opening.
[0034] The heat dissipation structure also has a groove recessed in the inner wall of the first opening, wherein the limiting part abuts against the end face of the first opening, the snapping part snaps into the groove, and the limiting part and the snapping part cooperate to clamp the heat dissipation structure.
[0035] In some embodiments, there are multiple electrical terminals and multiple base portions. The periphery of the multiple base portions is connected in sequence. The multiple electrical terminals correspond one-to-one with the multiple base portions. Each electrical terminal passes through the corresponding base portion. A limiting portion is provided on at least one base portion.
[0036] In some embodiments, the number of latching portions can be multiple, and the multiple latching portions are arranged at intervals along the periphery of multiple seat portions;
[0037] The limiting part is arranged around the periphery of multiple seat parts.
[0038] In some embodiments, a guide protrusion is provided on one of the outer wall surface of the seat portion and the inner wall surface of the first opening, and a guide groove is provided on the other of the outer wall surface of the seat portion and the inner wall surface of the first opening. The guide groove extends along the insertion direction of the insulating seat, and the guide protrusion is inserted into the guide groove.
[0039] In some embodiments, the first circuit module includes a first circuit board and a second circuit board, wherein the first circuit board is a filter board and the second circuit board is a driver board.
[0040] In some embodiments, the electronic control device further includes:
[0041] The third circuit board is located inside the housing and has a second opening. The insulating base and the power connection post both pass through the second opening.
[0042] Thirdly, embodiments of this application provide a heating, ventilation, and air conditioning (HVAC) device, including a housing and an electrical control device according to any of the above embodiments, wherein the electrical control device is disposed within the housing.
[0043] In some embodiments, the housing is provided with an access port; the electronic control device is located at the access port.
[0044] The connector, electrical control device, and HVAC equipment provided in this application include an insulating base and a contact post. The insulating base is disposed within a housing, and the contact post is disposed within the insulating base. Each contact post has two connected contact ends, each with a contact protrusion at its end. Each contact protrusion protrudes radially from the periphery of the contact post. The two contact protrusions are respectively connected between a first circuit module and a second circuit module to electrically connect the first and second circuit modules. Thus, compared to electrical control devices in related technologies, the insulating base and contact post of the connector in this application can be pre-installed within the housing. The insulating base defines the connection position within the connector, and the operator only needs to align the first and second circuit modules with the two contact protrusions to complete the wiring process. This helps reduce the wiring difficulty of the electrical control device in HVAC equipment and also lowers the error rate. Furthermore, the connector in this application can be connected between the first and second circuit modules via the two contact protrusions of the contact post, which helps shorten the physical distance between the first and second circuit modules, thereby reducing the length of the contact post itself and saving manufacturing materials. Furthermore, the connector of this application connects to the first and second circuit modules respectively via two contact protrusions on the contact post, eliminating the need for the connector, the first circuit module, and the second circuit module to be on the same plane. This facilitates a more three-dimensional and miniaturized design of the electrical control device for HVAC equipment. Simultaneously, both ends of the contact post have radially protruding contact protrusions, which help increase the contact area between the contact post and the first and second circuit modules, thereby ensuring a stable connection between the connector and the first and second circuit modules.

[0063] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0064] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0065] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0066] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.
[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0068] Heating, ventilation, and air conditioning (HVAC) systems are used to regulate the indoor environment, including functions such as heating, ventilation, and air conditioning. Their main purpose is to provide users with a comfortable and healthy indoor environment by controlling parameters such as temperature, humidity, and airflow. Common HVAC equipment includes air conditioners, radiators, and ventilation systems. These devices are widely used in residential, commercial buildings, and industrial settings.
[0069] Taking HVAC equipment as an example, the air conditioning system can be a multi-split system for buildings, that is, multiple indoor units are connected in parallel relative to one or more outdoor units 10, forming a refrigerant circuit so that the refrigerant can circulate. Figure 1 The diagram shows the outdoor unit 10 of the air conditioning system. The outdoor unit 10 has a casing 20, inside which are housed a compressor, switching valve, outdoor heat exchanger, outdoor expansion valve, and oil separator, etc. These components are connected by refrigerant piping. Additionally, a blower fan is installed in the outdoor unit 10.
[0070] Furthermore, the outdoor unit 10 also includes an electrical control device 30, which can be box-shaped. The housing 20 is the external structure of the outdoor unit 10, protecting internal components, providing a mounting base, and optimizing airflow. The housing 20 can be made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance. The housing 20 can be cuboid and placed on the roof or ground. The housing 20 isolates internal live components from the outside environment, preventing direct contact by users and reducing the occurrence of electric shock and other safety accidents. The electrical control device 30 is the core control component of the HVAC equipment. Installed inside the housing 20, it facilitates maintenance and replacement, and also streamlines the installation and layout of the overall HVAC structure. The electrical control device 30 is responsible for precisely controlling the operation of the HVAC equipment. It is equipped with various control circuits and uses various electronic components and wiring to control the HVAC equipment's start-up, stop, temperature adjustment, mode switching, and other operations.
[0071] The housing 20 provides protection for the electronic components within the electronic control device 30, preventing dust, moisture, oil, and other external impurities from entering. It also protects the device from extreme environmental conditions (such as temperature, humidity, and chemical corrosion), ensuring normal operation in various environments and extending the device's lifespan. Since the electronic control device 30 contains high-voltage circuits and live components, housing it within the housing 20 prevents accidental contact, reduces the risk of electric shock, and improves safety. Furthermore, the housing 20 acts as a shield, reducing external electromagnetic interference to the electronic components within the device, thus ensuring the stability and reliability of the control system.
[0072] In this embodiment, the housing 20 is rectangular, and the electronic control device 30 has a length direction, which is arranged along the height direction (i.e., the vertical direction) of the housing 20. Therefore, the internal structure of the electronic control device 30 has a vertical arrangement. This vertical length arrangement can better meet the overall structural layout requirements of the equipment when the housing 20 has a large height and limited horizontal space, and is also conducive to heat dissipation and maintenance.
[0073] It should be noted that the present invention is not limited to the arrangement of the electronic control device 30 along the height direction of the housing 20 in the above embodiments. In other embodiments, the electronic control device 30 may also be arranged along the length direction of the housing 20, or the electronic control device 30 may also be arranged along the width direction of the housing 20. Furthermore, the electronic control device 30 may not be a single form extending along the length direction; it may also vary according to the internal space of the housing 20, for example, it may be configured as an approximate "U" shape, or a similar "U" shape.
[0074] In some embodiments, an air duct is formed within the housing 20. This air duct guides air to flow along a predetermined path, preventing disordered airflow within the housing 20 and thus improving heat dissipation efficiency. Specifically, as exemplarily shown in the figure, the air supply fan is located at the top of the housing 20, i.e., at the top of the air duct, and blows air upwards. Furthermore, the electronic control device 30 is located within the air duct, so that the airflow within the air duct can carry away the heat generated by the electronic control device 30, ensuring effective heat dissipation for the electronic control device 30.
[0075] Please continue reading. Figure 1 In some embodiments, the housing 20 is provided with an access port 20a. In one configuration, the housing 20 includes a housing body and an access door rotatably connected to the housing body, allowing maintenance personnel to expose the access port 20a by opening the access door. In another configuration, the housing 20 includes a housing body and a front panel connected to the housing body. The front panel is fixedly connected to the housing body by screws, allowing maintenance personnel to separate the front panel from the housing body by removing the screws to expose the access port 20a. This application does not impose specific limitations on the manner in which the access port 20a is exposed.
[0076] The electronic control device 30 is located at the access port 20a, allowing maintenance personnel to quickly access it without having to extend excessively into the housing 20, thus greatly improving the efficiency of maintenance and repair.
[0077] Please see Figure 2 In some embodiments, the electronic control device 30 includes a housing 100 and a drive frequency converter assembly. The housing 100 is the main structure of the electronic control device 30, and the drive frequency converter assembly is disposed inside the housing 100. The drive frequency converter assembly is housed within the drive frequency converter cavity, meaning that the housing 100 serves to support and protect the internal drive frequency converter assembly, preventing it from shifting or being damaged due to external vibration or collision during use. By using the housing 100, components such as the drive frequency converter cavity are integrated into a unified structure, which facilitates the overall design and assembly of the electronic control device 30, and makes production and maintenance easier.
[0078] Please see Figures 2 to 4In some embodiments, the drive frequency converter assembly includes a first circuit module 210 and a second circuit module 220. The drive frequency converter cavity includes a first cavity 101 and a second cavity 102. Understandably, the housing 100 is a frame structure with a certain thickness. The first cavity 101 and the second cavity 102 are arranged relatively spaced apart in the thickness direction of the housing 100, that is, a portion of the housing 100 separates the first cavity 101 and the second cavity 102. By setting the first cavity 101 and the second cavity 102, the partitioned layout of different functional modules is realized. For example, different functional circuit modules can be arranged in the first cavity 101 and the second cavity 102. In this embodiment, the first circuit module 210 is disposed within the first cavity 101, and the second circuit module 220 is disposed within the second cavity 102. The thickness direction of the first circuit module 210 and the second circuit module 220 is consistent with the thickness direction of the housing 100. When viewed from the thickness direction of the housing 100 (i.e., from one side to the other), the first circuit module 210 and the second circuit module 220 are arranged sequentially along the thickness direction of the housing 100, rather than being placed horizontally or diagonally. This layout allows the first circuit module 210 and the second circuit module 220 to fully utilize the space of the housing 100 in the thickness direction, making reasonable use of the internal space of the electronic control device 30 and resulting in a more compact overall structure. This design can achieve more functions within a limited space and is suitable for applications with high space requirements.
[0079] In some embodiments, the housing 100 includes a heat dissipation structure 110 and a cover. The cover is sealingly connected to the heat dissipation structure 110 to form a first cavity 101 and a second cavity 102. Specifically, the cover includes a first cover 120 and a second cover 130. The heat dissipation structure 110 is the main body of the housing 100, and a portion of the heat dissipation structure 110 can be made of a material with good thermal conductivity, such as aluminum alloy. The heat dissipation structure 110 can be designed with internal heat dissipation channels. The heat dissipation channels can be straight or curved, used to guide the flow of the heat exchange medium, such as air or liquid, i.e., to remove heat through air cooling or water cooling. The first cover 120 and the second cover 130 are both cover-shaped structures with an opening on one side. The first cover 120 and the second cover 130 can be respectively disposed on the front and rear sides of the heat dissipation structure 110, that is, along the thickness direction of the shell 100. The first cover 120 is disposed on the heat dissipation structure 110 and cooperates with the heat dissipation structure 110 to form the first cavity 101. The first cavity 101 is used to install and accommodate the first circuit module 210. The second cover 130 is disposed on the heat dissipation structure 110 and cooperates with the heat dissipation structure 110 to form the second cavity 102. The second cavity 102 is used to install and accommodate the second circuit module 220. The first cover 120 and the second cover 130, through their tight cooperation with the heat dissipation structure 110, can effectively prevent external pollutants such as dust and moisture from entering the interior of the first cavity 101 and the second cavity 102.
[0080] The heat dissipation structure 110 can serve as part of the cavity wall of the first cavity 101 and the second cavity 102, thereby more effectively conducting the heat dissipated by the first circuit module 210 and the second circuit module 220 installed in the first cavity 101 and the second cavity 102, increasing the heat exchange area, improving heat dissipation efficiency, and ensuring that the first circuit module 210 and the second circuit module 220 remain stable under high load operation.
[0081] Furthermore, the heat dissipation structure 110 is used as part of the cavity wall of the first cavity 101 and the second cavity 102. That is, the heat dissipation structure 110 directly participates in the formation of the outer shell wall of the housing 100. In this way, when the electronic control device 30 is located in the air duct, the airflow in the air duct can quickly flow through the outer wall surface of the electronic control device 30, thereby fully exchanging heat. This allows for a faster release of the heat generated by the electronic control device 30.
[0082] Understandably, the first circuit module 210 and the second circuit module 220 generate heat during operation. At least one side of each module faces the heat dissipation structure 110. Since the thickness direction of the first and second circuit modules 210 is consistent with the thickness direction of the housing 100, the side facing the heat dissipation structure 110 is usually the larger side of the first and second circuit modules 210. The heat from these sides is mainly transferred to the heat dissipation structure 110 through thermal conduction, and then dissipated to the external environment through the heat dissipation function of the heat dissipation structure 110. Through the thermal conduction and convection heat dissipation functions of the heat dissipation structure 110, the heat generated by the first and second circuit modules 210 can be quickly removed, maintaining the internal temperature of the electronic control device 30 within a reasonable range. The sides of the first and second circuit modules 210 that face away from the heat dissipation structure 110 face the first cover 120 and the second cover 130, respectively. These sides can dissipate heat to the surrounding environment through radiation. This comprehensive heat dissipation strategy not only improves the efficiency of heat transfer, but also ensures the stability and reliability of the equipment during long-term operation.
[0083] Please see Figure 3 , Figure 4 , Figure 7 and Figure 9The heat dissipation structure 110 has a first side 111 and a second side 112, namely the front and rear sides of the heat dissipation structure 110 along the thickness direction of the housing 100. The first cavity 101 and the second cavity 102 are located on the first side 111 and the second side 112 of the heat dissipation structure 110, respectively. The first cover 120 and the second cover 130 can be tightly fitted with the heat dissipation structure 110 by screws, clips or other fixing devices to form two relatively independent first cavities 101 and second cavities 102. The heat generation and heat dissipation requirements of the first circuit module 210 and the second circuit module 220 may be different. By placing them in independent cavities, customized designs can be made according to the specific heat dissipation requirements of the first circuit module 210 and the second circuit module 220. It also effectively avoids heat cross-interference between the first circuit module 210 and the second circuit module 220, ensuring that the first circuit module 210 and the second circuit module 220 each have better matching heat dissipation settings, thereby improving the heat dissipation efficiency of the entire electronic control device 30.
[0084] Please see Figures 4 to 6 The portion of the housing 100 located between the first cavity 101 and the second cavity 102 is provided with a first opening 113, which means that the portion of the housing 100 that separates the first cavity 101 and the second cavity 102 is provided with a first opening 113, and the first opening 113 connects the first cavity 101 and the second cavity 102.
[0085] The electronic control device 30 also includes a connector 40, which can electrically connect the first circuit module 210 and the second circuit module 220.
[0086] Connector 40 passes through the first opening 113 and connects to the first circuit module 210 and the second circuit module 220 at both ends, respectively, to electrically connect the first circuit module 210 and the second circuit module 220. The arrangement of the first opening 113 and connector 40 simplifies the connection between circuits and reduces the complexity and length of internal wiring. Although the first circuit module 210 and the second circuit module 220 are electrically connected through connector 40, they still maintain a certain degree of physical isolation, which helps to maintain their respective operating environments, such as temperature, vibration, and contamination.
[0087] By providing a first opening 113 and a connector 40 inside the housing 100, the connection between the first circuit module 210 and the second circuit module 220 can be completed inside the housing 100 without the need for external wiring. This reduces the need for external wiring between the first circuit module 210 and the second circuit module 220, making the overall layout of the electronic control device 30 simpler. Furthermore, due to the reduction in external wiring, the number and size of the wiring holes in the housing 100 can be reduced accordingly, which helps improve the sealing performance of the housing 100, thereby better protecting the internal circuit modules from the intrusion of dust, moisture, and other contaminants.
[0088] Since the first circuit module 210 and the second circuit module 220 in the first cavity 101 and the second cavity 102 have relatively independent functions and are connected by the connector 40, this cavity design makes the internal functional division of the electronic control device 30 clearer, which is convenient for management and maintenance. When it is necessary to maintain or repair a certain circuit module, the problem can be located more quickly, reducing the impact on the other circuit module and improving maintenance efficiency.
[0089] Furthermore, the first circuit module 210 and the second circuit module 220 are located in independent cavities and are electrically connected via connector 40. Their main bodies are isolated by housing 100. This layout effectively reduces signal interference between the first circuit module 210 and the second circuit module 220. In the electronic control device 30, signal interference is one of the important causes of equipment instability and malfunction. The cavity design significantly reduces this interference and improves the reliability of the electronic control device 30.
[0090] Among them, such as Figure 9 As shown, the heat dissipation structure 110 is provided with a first opening 113. The first opening 113 can be located in the middle part of the heat dissipation structure 110, allowing the connector 40 to pass directly through the heat dissipation structure 110 with a shorter path, connecting the first circuit module 210 and the second circuit module 220 within the first cavity 101 and the second cavity 102. This design not only reduces the length of the connector 40 and lowers material costs, but also reduces signal transmission losses and improves the efficiency and stability of the electrical connection. Because the connector 40 has the shortest path, the internal space of the electronic control device 30 can be utilized more efficiently, reserving more space for other electronic components or functional modules.
[0091] In some embodiments, the first circuit module 210 includes a first circuit board 211 and a second circuit board 221, wherein the first circuit board 211 is a filter board and the second circuit board 221 is a driver board.
[0092] The driver board is typically used to implement the main functions of the electronic control device 30, such as control and drive. In this embodiment, the driver board is located within the first cavity 101. The second circuit module 220 is a filter board, which is used to filter high-frequency noise in the power supply, smooth DC voltage, and suppress electromagnetic interference, that is, to filter the electrical signal, remove noise and interference, and ensure the purity of the electrical signal. In this embodiment, the filter board is located within the second cavity 102. Continuing from the above, the driver board is located on the side facing the inspection port 20a, and the filter board is located on the side away from the inspection port 20a. The driver board typically integrates multiple functional circuits. For example, the insulated-gate bipolar transistor (IGBT) commonly found in driver boards is a device with a high failure rate. Due to the complexity and high failure rate of the driver board, it requires more frequent maintenance. Therefore, placing it on the side facing the inspection port 20a makes it easier for maintenance personnel to maintain. Compared to the driver board, the filter board has a relatively low failure rate. Common problems are mostly related to electrical parameter adjustment or mechanical connection issues, which are relatively easy to solve, thus requiring less frequent maintenance. Furthermore, the heat generated by the driver board is higher than that of the driver board. Therefore, when the filter board is located on the back side, it can more effectively utilize the airflow of the air duct to remove the corresponding heat, resulting in better heat dissipation efficiency.
[0093] From a heat dissipation perspective, the filter board is located in the first cavity 101, while the drive board is located in the second cavity 102. This compartmentalized design avoids heat accumulation in a single cavity. A portion of the heat dissipation structure 110 forms a shared cavity wall between the first cavity 101 and the second cavity 102. This cavity wall not only serves as a physical separator but also acts as a heat conduction channel. Specifically, the material and structural design of the cavity wall allow heat to be efficiently conducted from higher-temperature components (such as the drive board) to the heat dissipation structure 110, thereby achieving rapid heat dissipation. This design not only effectively avoids localized overheating caused by heat accumulation but also further optimizes the heat dissipation performance of the entire electronic control device 30 by rationally distributing heat, ensuring the stability and reliability of the drive board and filter board during long-term operation.
[0094] Please see Figure 3 , Figure 4 , Figure 10 as well as Figure 11The connector 40 may include an insulating base 300 and a power contact post 400. The insulating base 300 is disposed within the housing 100, and the power contact post 400 is disposed within the insulating base 300. The power contact post 400 has two connected power contact ends 410. Each power contact end 410 has a power contact protrusion 420 at its end. Each power contact protrusion 420 protrudes radially from the periphery of the power contact post 400. The two power contact protrusions 420 are respectively connected between the first circuit module 210 and the second circuit module 220 to electrically connect the first circuit module 210 and the second circuit module 220. Thus, compared to the electrical control device 30 in the related technology, the insulating seat 300 and the power contact post 400 of the connector 40 can be pre-installed in the housing 100 to define the connection position in the connector 40 through the insulating seat 300. The operator only needs to connect the first circuit module 210 and the second circuit module 220 with the two power contact protrusions 420 to complete the wiring process, which helps to reduce the wiring difficulty of the electrical control device 30 of the HVAC equipment and also has a lower error rate.
[0095] Furthermore, the connector 40 of this application can be connected between the first circuit module 210 and the second circuit module 220 respectively through the two electrical protrusions 420 of the electrical contact post 400, which helps to shorten the physical distance between the first circuit module 210 and the second circuit module 220, thereby helping to reduce the length of the electrical contact post 400 itself, and thus helping to save the manufacturing materials of the electrical contact post 400.
[0096] Moreover, in related technologies, the modules of the electrical control device need to be set on the same plane. In this application, the connector 40 is connected between the first circuit module 210 and the second circuit module 220 through the two power-connecting protrusions 420 of the power-connecting post 400, so that the connector 40, the first circuit module 210 and the second circuit module 220 do not need to be set on the same plane, which helps to make the design of the electrical control device 30 of the HVAC equipment more three-dimensional and miniaturized.
[0097] Meanwhile, both ends of the power contact post 400 are provided with radially protruding power contact protrusions 420. The power contact protrusions 420 help to increase the contact area between the power contact post 400 and the first circuit module 210 and the second circuit module 220, so that the connector 40 can be stably connected to the first circuit module 210 and the second circuit module 220.
[0098] Each contact protrusion 420 is arranged in a ring shape. This ring-shaped contact protrusion 420 provides 360° omnidirectional contact, ensuring a stable electrical connection in any direction. Even under vibration, impact, or other external interference, the ring-shaped contact protrusion 420 maintains good contact, preventing open circuits or signal interruptions caused by poor local contact.
[0099] Each power-contacting protrusion 420 has a power-contacting plane 421 on its end face. The two power-contacting planes 421 are respectively attached to the first circuit module 210 and the second circuit module 220. By using the power-contacting planes 421 to attach and connect with the first circuit module 210 and the second circuit module 220, for example, by attaching the two power-contacting planes 421 to the first circuit board 211 and the second circuit board 221 respectively, a tighter and flatter connection interface can be achieved. This avoids problems such as signal fluctuations or power transmission interruptions caused by insufficient contact or unstable contact points, thereby improving the reliability and stability of the connector 40 during long-term use.
[0100] The two electrical contact protrusions 420 cooperate to clamp the two ends of the insulating base 300, thereby restricting the axial movement of the insulating base 300 along the electrical contact post 400, and thus preventing the insulating base 300 from separating from the electrical contact post 400 along the axial direction of the electrical contact post 400.
[0101] Please see Figure 10 and Figure 11 The insulating base 300 is provided with a mounting through hole 301, and the electrical connection post 400 passes through the mounting through hole 301. The two electrical connection ends 410 and the two electrical connection protrusions 420 are partially exposed outside the mounting through hole 301, so that the insulating base 300 can be fixedly engaged with the electrical connection post 400.
[0102] The insulating base 300 has mounting grooves 302 at both ends along its length, which communicate with the mounting through holes 301. Each mounting groove 302 corresponds to one of the two contact protrusions 420. Each contact protrusion 420 is partially embedded in its corresponding mounting groove 302, allowing the contact post 400 and the insulating base 300 to fit more tightly, thus helping to reduce the size of the connector 40. Furthermore, it also helps to increase the contact area between the contact post 400 and the insulating base 300, allowing the contact post 400 to be more securely positioned within the insulating base 300.
[0103] The inventors discovered that in order to further improve the stability of the connection between the power supply post 400 and the first circuit module 210 and the second circuit module 220, the power supply post 400 is generally connected to the power supply post 400 by bolt thread and together clamp the first circuit module 210 and the second circuit module 220. During the process of bolt thread connection to the power supply post 400, the insulating seat 300 is prone to relative rotation with the power supply post 400, which causes the bolt to not be effectively threaded to the insulating seat 300 during the assembly process.
[0104] Please see Figures 12 to 15The inner wall of the mounting through hole 301 is provided with a first anti-rotation structure 310, and the terminal post 400 is provided with a second anti-rotation structure 430 located within the mounting through hole 301. The second anti-rotation structure 430 and the first anti-rotation structure 310 are mutually restrictive to limit the rotation of the terminal post 400 relative to the insulating seat 300. By providing the first anti-rotation structure 310 on the inner wall of the mounting through hole 301 and the corresponding second anti-rotation structure 430 on the terminal post 400, the mutually restrictive cooperation effectively limits the rotation of the terminal post 400 relative to the insulating seat 300, thereby ensuring that the bolt can be smoothly and securely threaded onto the terminal post 400.
[0105] The first anti-rotation structure 310 includes multiple first limiting ribs 311, which are arranged sequentially at intervals around the circumference of the connecting post 400, and each first limiting rib 311 extends along the axial direction of the connecting post 400. The second anti-rotation structure 430 includes multiple second limiting ribs 431, which are arranged sequentially at intervals around the circumference of the connecting post 400, and each second limiting rib 431 extends along the axial direction of the connecting post 400. The multiple second limiting ribs 431 and the multiple first limiting ribs 311 are arranged alternately. This alternate arrangement design creates a multi-point limiting fit between the first limiting ribs 311 and the second limiting ribs 431, which helps to improve the accuracy and reliability of the first anti-rotation structure 310 and the second anti-rotation structure 430, thereby more effectively limiting the rotation of the connecting post 400 relative to the insulating base 300.
[0106] In other embodiments, the first anti-rotation structure 310 may be one or more keyways (which may be a single long slot or multiple short slots) machined on the inner wall surface of the mounting through hole 301 of the insulating base 300. The direction of the keyways is usually arranged along the axial direction of the contact post 400, but it can also be designed in a spiral shape to increase friction as needed. The second anti-rotation structure 430 may be a matching key (or a protrusion) provided at a corresponding position on the outer surface of the contact post 400. These keys can be precisely inserted into the keyways on the insulating base 300. When the contact post 400 is inserted into the insulating base 300, the fit between the key and the keyway can prevent the contact post 400 from rotating, thereby achieving the anti-rotation function.
[0107] Please see Figure 10 and Figure 11The connector 40 also includes two connectors 500, with two electrical contact protrusions 420 corresponding one-to-one with each connector 500. One connector 500 is connected to the corresponding electrical contact protrusion 420 and together they clamp the first circuit module 210. The other connector 500 is connected to the corresponding electrical contact protrusion 420 and together they clamp the second circuit module 220. The connectors 500 can be threaded or plugged into the corresponding electrical contact protrusions 420. Thus, the connectors 500 and the electrical contact protrusions 420 work together to firmly fix the first circuit module 210 and the second circuit module 220 by clamping, avoiding loosening of the first and second circuit modules 210 and 220 due to vibration, impact, or changes in the external environment. This ensures tight contact between the electrical contact post 400 and the first and second circuit modules 210 and 220, significantly improving the reliability of the electrical connection.
[0108] Each connector 500 includes a connecting portion 510 and a clamping portion 520 connected together; one power-connecting protrusion 420 is threadedly connected to the corresponding connecting portion 510 and cooperates with the corresponding clamping portion 520 to clamp the first circuit module 210; another power-connecting protrusion 420 is threadedly connected to the corresponding connecting portion 510 and cooperates with the corresponding clamping portion 520 to clamp the second circuit module 220. Each power-connecting end 410 and the corresponding power-connecting protrusion 420 cooperate to form a connecting hole. The inner wall of the connecting hole has an internal thread structure, and the connecting portion 510 has an external thread structure. The external thread structure of the connecting portion 510 can be threadedly connected to the internal thread structure of the connecting hole. Thus, the threaded connection (screw or bolt) between the connecting portion 510 and the power-connecting protrusion has a self-locking characteristic, maintaining stability when the equipment is subjected to vibration, impact, or other external interference. Simultaneously, the design of the clamping portion 520 provides additional mechanical support, forming a robust clamping structure between the power-connecting protrusion 420 and the circuit module, significantly enhancing the overall connection's vibration resistance, making it particularly suitable for applications in industrial environments or mobile devices.
[0109] Furthermore, the adjustability of the threaded connection between the connecting portion 510 and the power-connecting protrusion 420 allows the distance between the power-connecting protrusion 420 and the clamping portion 520 to be flexibly adjusted according to the thickness of the circuit module. This design provides reliable clamping force for both thinner flexible circuit boards and thicker rigid circuit boards, thus offering greater versatility and adaptability.
[0110] The insulating base 300 is equipped with a mounting structure that cooperates with the installation environment of the electronic control device 30 to fix the insulating base 300 within the housing 100. The installation environment can be the housing 100, the first circuit module 210, or the second circuit module 220, etc. The mounting structure can be customized according to different installation environments, for example, by using snap-fit, threaded holes, or sliding grooves for fixation. In this way, the mounting structure on the insulating base 300 can fit tightly with the housing 100 or the installation environment, ensuring that the connector 40 is firmly fixed within the housing 100, thereby effectively preventing loosening or displacement caused by vibration, impact, or other external factors, and improving the overall mechanical stability of the connector 40. Furthermore, by firmly fixing the insulating base 300 within the housing 100 through the mounting structure, it can effectively resist the effects of external vibration or impact.
[0111] Please see Figures 6 to 9 In some embodiments, the connector 40 includes an insulating base 300 and a contact post 400. The insulating base 300 is installed at a first opening 113. A plurality of latching slots 114 are spaced apart on the inner wall of the first opening 113. The insulating base 300 includes a latching portion 340 that mates with the latching slots. By latching the latching portion 340 into the latching slot 114, the insulating base 300 is securely installed at the first opening 113 of the heat dissipation structure 110. In other embodiments, the insulating base 300 can also be installed at the first opening 113 by riveting, bonding, or other methods. The insulating base 300 serves as insulation, preventing current leakage or short circuits and ensuring electrical safety. The contact post 400 is mounted on the insulating base 300. The contact post 400 can be fixed to the insulating base 300 by crimping, welding, or pre-embedded in the cavity via injection molding, connecting to the insulating base 300 as a single unit during molding. In other words, the insulating base 300 provides fixation and support for the contact post 400, maintaining connection stability and preventing loosening due to vibration or other reasons. The contact post 400 extends axially along the thickness direction of the housing 100, passing through the first opening 113, and connects to the first circuit module 210 and the second circuit module 220 at both ends. The contact post 400 is typically made of conductive material, such as copper or copper alloy, effectively conducting current to transmit electrical signals and ensure normal circuit operation.
[0112] Specifically, such as Figure 10As shown, the insulating base 300 includes a base body 320 and a limiting part 330 and a latching part 340 respectively connected to the base body 320. The base body 320 is the main body of the insulating base 300 and is used to support the power connection post 400. The power connection post 400 passes through the base body 320 and provides a basic structure for installing the limiting part 330 and the latching part 340. The limiting part 330 protrudes from the outer wall surface of the base body 320 and is arranged around the circumference of the base body 320. The latching part 340 and the limiting part 330 are spaced apart along the depth direction of the first opening 113. That is, the limiting part 330 is located on one side of the base body 320, while the latching part 340 is closer to the other side of the base body 320 than the limiting part 330. When the insulating base 300 is installed in the first opening 113, the limiting part 330 abuts against the end face connecting the first opening 113. The limiting part 330 can limit the position of the insulating base 300 in the depth direction of the first opening 113. This ensures that the insulating base 300 is accurately positioned on the heat dissipation structure 110 and prevents the insulating base 300 from shifting during installation.
[0113] Among them, such as Figures 5 to 8 As shown, the heat dissipation structure 110 also has a recessed groove 114 formed on the inner wall of the first opening 113. The latching part 340 is latched into the groove 114. The latching part 340 is usually designed to have a certain degree of elasticity, so that it can be latched into the groove 114 of the heat dissipation structure 110 through elastic deformation. Multiple latching parts 340 are provided, and multiple latching parts 340 are spaced apart along the outer periphery of the base part 320 to provide a more stable fixing force and prevent loosening caused by uneven local force. Moreover, the design of multiple latching parts 340 improves the reliability of the overall structure. Even if one latching part 340 fails due to external force or wear, the other latching parts 340 can still keep the insulating base 300 fixed.
[0114] Furthermore, the limiting part 330 and the snap-fit part 340 cooperate to clamp the heat dissipation structure 110. Specifically, the limiting part 330 restricts the position of the insulating seat 300 on one side of the depth direction of the first opening 113, while the snap-fit part 340 snaps into the snap-fit groove 114 on the other side of the depth direction of the first opening 113, so that the limiting part 330 and the snap-fit part 340 cooperate to clamp the wall in the depth direction of the first opening 113. This ensures that the insulating seat 300 is accurately positioned and firmly fixed on the heat dissipation structure 110, and will not loosen even under vibration or impact.
[0115] Furthermore, such as Figure 6As shown, in some embodiments, a guide protrusion 350 is provided on one of the outer wall surface of the base portion 320 and the inner wall surface of the first opening 113, while a guide groove 115 is provided on the other of the outer wall surface of the base portion 320 and the inner wall surface of the first opening 113. The guide groove 115 extends along the insertion direction of the insulating base 300, and the guide protrusion 350 is inserted into the guide groove 115. The cooperation between the guide protrusion 350 and the guide groove 115 can significantly improve the accuracy and efficiency of installation. The guide protrusion 350 and the guide groove 115 can smoothly guide the insulating base 300 to be inserted into the first opening 113 of the heat dissipation structure 110 in the correct direction, ensuring the smooth progress of the installation process.
[0116] In this embodiment, the guide protrusion 350 is disposed on the base portion 320, and the guide protrusion 350 extends along the depth direction of the first opening 113. The depth direction of the first opening 113 is the same as the thickness direction of the main body. The guide protrusion 350 is used to guide the insulating base 300 to be correctly inserted into the first opening 113 of the heat dissipation structure 110 during installation. The wire protrusion can be disposed between two adjacent snap-fit portions 340. During installation, the guide protrusion 350 of the insulating base 300 is aligned with the guide groove 115 of the heat dissipation structure 110 to ensure that the guide protrusion 350 can be inserted smoothly. At the same time, the snap-fit portion 340 is automatically aligned with the snap groove 114 on the heat dissipation structure 110. The snap-fit portion 340 is snapped into the snap groove 114 through elastic deformation to complete the fixation of the insulating base 300.
[0117] The guide protrusion 350 is located on one side of the base portion 320 along the height direction. This asymmetrical design gives the insulating base 300 a clear directionality during installation. Operators can easily determine the correct installation direction of the insulating base 300 by observing the positions of the guide protrusion 350 and the guide groove 115, avoiding installation failures due to incorrect orientation.
[0118] Both the insulating base 300 and the contact post 400 pass through the first opening 113. The contact post 400 can penetrate directly from one side of the housing 100 to the other, allowing circuit modules (such as the first circuit module 210 and the second circuit module 220) to be arranged more compactly in three-dimensional space, rather than being confined to the same plane. This makes the connector 40 fit more compactly with the housing 100 of the electronic control device 30, thereby helping to reduce the size of the electronic control device 30.
[0119] In some embodiments, the terminal post 400 is generally made of a metal material with good conductivity and mechanical strength, such as copper alloy or aluminum alloy. The insulating base 300 is usually made of engineering plastics, such as polycarbonate or nylon. During the injection molding process of the insulating base 300, a pre-drilled hole is generally provided in the mold for placing the terminal post 400. After the terminal post 400 is precisely placed in the designated position in the mold, molten plastic material is injected into the mold. The plastic completely fills the mold and tightly wraps the terminal post 400. After the injected plastic cools and solidifies, a solid insulating base 300 is formed, so that the terminal post 400 is firmly embedded inside the insulating base 300.
[0120] The terminal 400 can be made of conductive copper rod. Designing the terminal 400 as a conductive copper rod can significantly reduce resistance, reduce energy loss during current transmission, and improve the efficiency of electrical connection, making it especially suitable for high-power or high-frequency signal transmission scenarios.
[0121] Furthermore, due to the low resistance of copper, the terminal 400 generates less heat when transmitting large currents, thus reducing the temperature rise caused by resistive heating. This not only improves the operating efficiency of the electrical control device 30 but also reduces the potential risk of failure due to overheating, extending the service life of the equipment.
[0122] Furthermore, copper possesses excellent oxidation and corrosion resistance. Especially at room temperature, a dense oxide film forms on the copper surface, further protecting the internal materials from corrosion. This characteristic enables the contact post 400 to maintain stable electrical performance over long periods in humid or harsh environments, enhancing the reliability of the connector 40.
[0123] Please see Figure 10 The connector 400 has multiple terminals 400 and multiple base portions 320, with the peripheries of the multiple base portions 320 connected sequentially. The multiple base portions 320 can be arranged according to the connection requirements of the first circuit module 210 and the second circuit module 220. Each terminal 400 corresponds one-to-one with a base portion 320, and each terminal 400 passes through its corresponding base portion 320. A limiting portion 330 is provided on at least one base portion 320. Specifically, the two terminal protrusions 420 of each terminal 400 are respectively connected to the first circuit module 210 and the second circuit module 220. Thus, the design of multiple terminals 400 allows for multiple independent electrical connections to be made simultaneously. This not only increases the functionality of the connector 40 but also supports various different electrical requirements, such as power supply and signal transmission, improving the overall flexibility and adaptability of the device.
[0124] Furthermore, in applications requiring high-power or three-phase power transmission, using multiple terminals 400 can achieve more efficient and stable power transmission. For example, three-phase power supply is common practice in industrial automation equipment or large motor drive systems. By designing multiple terminals 400 to correspond to each line of the three-phase power supply, uniform current distribution can be ensured, reducing the stress on individual connection points and thus improving system reliability and safety.
[0125] Furthermore, the combined operation of multiple terminals 400 can distribute the total current load, reducing the current density on each individual terminal 400 and preventing overheating. This is particularly important for applications requiring high current handling, effectively improving the safety performance of the entire electronic control device 30.
[0126] In some embodiments, the number of latching portions 340 can be multiple, and the multiple latching portions 340 are arranged at intervals along the periphery of the multiple seat portions 320. The limiting portion 330 is arranged around the periphery of the multiple seat portions 320. That is, the multiple seat portions 320 form a whole, and the multiple latching portions 340 can be arranged at intervals along the periphery of this whole, and the limiting portion 330 is arranged at intervals around the periphery of this whole. In this way, the multiple latching portions 340 and the limiting portion 330 cooperate to clamp the heat dissipation structure 110, which helps to reduce the risk of the connector 40 becoming loose in the housing 100 due to the damage of a single latching portion 340, thereby helping to improve the firmness of the connector 40 fixed in the housing 100.
[0127] In some embodiments, the electronic control device 30 may further include a third circuit board, which may be a power board or an active board, etc. The third circuit board may be disposed within the housing 100, and can be installed in a suitable position within the housing 100. The connector 40 may pass through the second opening, and the connector 40 may be connected to the third circuit board by means of snap-fit connection or screw connection, thereby facilitating the fixed connection of the connector 40 to the third circuit board. The third circuit board may be stacked between the first circuit board 211 and the second circuit board 221.
