[0025] Please refer to the following in order. Figures 1 to 5This application provides a connection terminal 10 for connecting main power boards. The connection terminal 10 includes an insertion part 101 and a fixing part 102. The components are described below:

[0026] The insertion part 101, as a component of the overall connection terminal 10, has a plurality of pins 1011 formed on the side away from the fixing part 20. The pins 1011 are used to insert into the plug-in holes 201 on the first main power board 20 and achieve reliable electrical connection with the conductive circuit on the first main power board 20 by means of wave soldering or the like, thereby completing the first end connection of the power conduction path.

[0027] The fixing part 102, as another component of the integral connecting terminal 10, is perpendicular to the insertion part 101 and has a fixing structure 1021 formed on the side away from the insertion part 101. In this embodiment, the fixing structure 1021 can be a through hole, a threaded hole, or a snap-fit ​​structure, used to fix the connecting terminal to the second main power board 30 together by means of screws, studs, crimping parts, etc., to achieve mechanical and stable support and prevent the terminal from loosening during transportation or use.

[0028] In this way, the connection terminal 10 connects the insertion part 10 and the fixing part 20 together by means of integral molding or welding, so that the two main power boards (first main power board 20 and second main power board 30) can be connected in space through the terminal, avoiding the problems of large space occupation, high cost and complicated assembly caused by traditional cable solutions.

[0029] It should be understood that both the insertion part 101 and the fixing part 102 are made of conductive material to ensure that the connection terminal has complete current conduction capability while fixing the inter-board structure. The specific material can be copper, copper alloy or other metal materials with good conductivity and solderability. If necessary, the surface can be tin-plated, nickel-plated or other treatments can be applied to improve conductivity and corrosion resistance.

[0030] As can be seen, the connection terminal in this embodiment is used to establish a power connection between two main power boards that are roughly parallel to each other. It mainly adopts an integrated design of the insertion part and the fixing part. The insertion part is stably soldered to the first main power board through multiple pins, and the fixing part is fixedly connected to the second main power board through a structure with threaded holes. This enables a direct, compact, and reliable power connection between the two main power boards. Compared with traditional cable connection methods, this structure significantly saves space, simplifies the installation process, reduces manufacturing and labor costs, avoids poor contact caused by improper assembly or loosening in cable connections, and effectively improves the structural integration and electrical connection reliability of the system. It is suitable for power system board connection applications with high power density and compact space requirements.

[0031] In an optional embodiment of this application, the insertion part 10 is a first plate body perpendicular to the fixing part 20, that is, the insertion part 10 and the fixing part 20 form a generally "L-shaped" spatial structure, which makes the connection terminals more compact in spatial arrangement and easier to adapt to the stacked main power boards.

[0032] Specifically, multiple pins are provided on the side of the first plate away from the fixing part 20. The pins are arranged in an array or at intervals for insertion into the insertion holes of the first main power board and for soldering fixation. Through the above structural design, the insertion part can stably establish an electrical connection with the first main power board. At the same time, since the insertion direction is arranged perpendicular to the main power board facing the fixing part, connection space can be effectively saved, and the integration and compactness of the overall structure can be improved.

[0033] Furthermore, multiple pins are arranged at intervals along the length of the first plate, meaning the pins are arranged equidistantly or non-equidistantly along the extension direction of the insertion part, which helps to improve the current carrying capacity and soldering stability of the connection terminals. This arrangement not only facilitates alignment with multiple insertion holes on the first main power board, but also enables multi-point parallel conduction in high-current applications, effectively reducing the current load per pin and improving the overall electrical connection reliability and heat resistance.

[0034] In an optional embodiment of this application, a first outer edge portion 103 and a second outer edge portion 104 are respectively provided on opposite sides of the first plate. The first outer edge portion 103 is located on one side edge of the first plate, and the second outer edge portion 104 is located on its opposite side edge, both extending along the length direction of the first plate.

[0035] Specifically, the first outer edge 103 has at least one pin on the side away from the fixing part 20 for inserting into and electrically connecting to the insertion hole of the first main power board; and the second outer edge 104 also has at least one pin on the side away from the fixing part 20, forming a symmetrical or parallel arrangement with the pin on the first outer edge 103. This embodiment, by providing pins on the two outer edges of the first board, not only increases the electrical connection area but also improves the current carrying capacity and soldering strength of the connection terminals, helping to achieve a more balanced current distribution and a more stable mechanical fixing effect, suitable for the connection needs between main power boards in high-power, high-reliability scenarios.

[0036] Meanwhile, the height of the first plate is smaller than the distance between the first main power board 20 and the second main power board 30. Specifically, the first plate refers to the vertical structural part of the insertion section, and its overall height from the insertion pin end to the area connected to the fixing part is preferably designed to be slightly smaller than the effective installation space between the upper and lower main power boards. This height-adaptive design ensures that the connection terminals can be smoothly inserted and mated with the two main power boards during assembly without interference, thereby avoiding assembly difficulties or connection stress caused by dimensional redundancy.

[0037] It should be noted that each pin protrudes outward in a direction perpendicular to the fixing part, that is, each pin extends outward from the side of the first plate away from the fixing part to form an insertable structure. The pin arrangement direction is orthogonal to the plate surface of the fixing part, so that the connection terminal has a clear insertion direction and force transmission path during installation.

[0038] In an optional embodiment of this application, the fixing part is a second plate perpendicular to the first plate, that is, the insertion part and the fixing part are arranged in an L-shaped structure in space, which helps to achieve a compact connection between the connection terminals and the two vertically arranged main power boards, and at the same time facilitates the transmission of force and installation operation.

[0039] Specifically, a fixing structure is provided in the central area of ​​the second plate. Located in the middle of the second plate, this fixing structure helps maintain balanced force on the connection terminals during installation and ensures their positioning accuracy and fastening strength on the second main power board. This structure is compatible with various standard fasteners, such as screws, studs, or locating pins, facilitating batch assembly and maintenance.

[0040] In addition, the fixing structure can be a through hole or a threaded hole, depending on the assembly requirements of the application scenario.

[0041] When the fixing structure is a through hole, it can work together with the screw and the nut or embedded part on the back of the second main power board to form a detachable fixing; when the fixing structure is a threaded hole, it can be directly engaged with the screw, which is convenient for quick installation and disassembly and is suitable for occasions that require high assembly efficiency.

[0042] Regardless of whether the fixing structure is a through hole or a threaded hole, the fixing structure is set in the central area of ​​the second plate and is used to align and cooperate with the preset fixing position set on the second main power board, thereby ensuring that the connection terminal is reliably fixed to the second main power board in terms of structure, avoiding problems such as loosening and displacement, and improving the stability and shock resistance of the overall connection system.

[0043] In an optional embodiment of this application, the connection terminal 10, through the insertion part 101 and the fixing part 102, is used to conduct the current of the first main power board 20 to the second main power board 30, or to conduct the current of the second main power board 30 to the first main power board 20.

[0044] Specifically, the insertion part 101 forms an electrical connection with the first main power board 20 through its pin 1011, and the fixing part 102 establishes a conductive contact with the second main power board 30 through structural fixation, so that the terminal becomes a current conduction bridge between the two main power boards after insertion. This design is not only suitable for unidirectional power supply scenarios, but also for complex circuit structures such as bidirectional current exchange, parallel connection of power modules, and load sharing, exhibiting good adaptability and versatility. In other words, this structural design ensures high-current, low-impedance, and high-reliability inter-board power conduction under compact layout conditions, meeting the requirements of modern power systems for highly integrated and high-efficiency connection components.

[0045] Please see Figure 6 In one optional embodiment, two insertion portions 101 are formed at each end of the connecting terminal 10, and corresponding pins are formed thereon. These pins are electrically connected to the first main power board and the second main power board respectively. Compared with the conventional "one-side insertion, one-side fixing" connection method, this dual-insertion structure can further improve the stability and electrical continuity of the connection, making it suitable for applications with high requirements for conduction efficiency, seismic performance, or assembly consistency. Simultaneously, this structure achieves structural positioning and connection without additional fixing parts, simplifying the assembly process and enhancing the modular flexibility of the connecting terminal.

[0046] This application also provides a power supply device, including a first main power board, a second main power board, and connection terminals as described in the above embodiments. The number of connection terminals is multiple, and they are respectively disposed between the first main power board and the second main power board.

[0047] The connection terminals and power supply devices for connecting main power boards according to embodiments of this application adopt an integrated design of insertion and fixing parts. The insertion part achieves a stable soldered connection to the first main power board via multiple pins, while the fixing part is fixedly connected to the second main power board via a structure with threaded holes. This enables a direct, compact, and reliable power connection between the two main power boards. Compared to traditional cable connection methods, this structure significantly saves space, simplifies the installation process, reduces manufacturing and labor costs, avoids poor contact caused by improper assembly or loosening in cable connections, and effectively improves the structural integration and electrical connection reliability of the system. It is suitable for power system board connection applications with high power density and compact space requirements.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
