[0030] The present invention provides a bus terminal 100 .

[0031] See also Figures 1 to 4 In one embodiment of the present invention, the bus terminal 100 includes a body 1, the body 1 has a first bending arm 11 and a second bending arm 12, the first bending arm 11 is connected to the second bending arm 12; an extension section 111 is protrudingly provided at one end of the first bending arm 11 away from the second bending arm 12, and the extension section 111 is connected to the first bending arm 11; wherein the extension section 111 is provided with a connecting portion 111a, and the connecting portion 111a is used to connect the body 1 and the bus 3; the second bending arm 12 is provided with a welding foot 121, and the welding foot 121 is used to connect the circuit board 2, and when the welding foot 121 is connected to the circuit board 2, the connecting portion 111a is exposed on the circuit board 2.

[0032] In this embodiment, by optimizing the structural design of the bus terminal 100, the function of fixing the circuit board 2 and the bus bar 3 from the front and back directions is realized, thereby solving the problem of limited fixing direction of the bus bar 3 and the circuit board 2 in the prior art. Specifically, the body 1 of the bus terminal 100 is designed to have a structure with a first bending arm 11 and a second bending arm 12, wherein an extension section 111 extends from one end of the first bending arm 11, and a connecting portion 111a is provided on the extension section 111 for connecting with the bus bar 3, and the connecting portion 111a can be a threaded hole, a slot or other connecting structure adapted to the bus bar 3; the second bending arm 12 is provided with a welding foot 121, and the welding foot 121 is used to connect with the circuit board 2, and the welding foot 121 can be a cylinder, a cuboid or other fixed structure adapted to the circuit board 2. In practical applications, for example, in a low-voltage relay matrix, the bus terminal 100 can be installed on the bus 3 through the connecting portion 111a, and the circuit board 2 is fixed to the bus terminal 100 through the soldering foot 121. When the soldering foot 121 is connected to the circuit board 2, the connecting portion 111a is exposed to the circuit board 2. The user can directly disassemble the connecting portion 111a on one side of the circuit board 2, and then take out the circuit board 2 simultaneously. This design allows the user to no longer be limited to a single direction, thereby improving the flexibility and convenience of assembly. In addition, in order to further optimize the assembly process, a guide structure, such as a guide groove or a positioning pin, can be provided on the connecting portion 111a and the soldering foot 121 of the bus terminal 100 to ensure that the bus 3 and the circuit board 2 can be quickly and accurately installed in place, reducing assembly time and error rate.

[0033] By adopting a two-directional fixed structure, the bus terminal 100 can break through the limitations of traditional designs and greatly improve the flexibility and convenience of circuit board 2 assembly. In the application scenario of large-scale low-voltage relay matrix, this design makes the installation of the bus 3 and the circuit board 2 no longer limited to a single direction, reducing the assembly difficulties and maintenance inconveniences caused by directional restrictions. For example, in situations where frequent maintenance and replacement of the circuit board 2 are required, the operator simply stands on one side of the circuit board 2 to disassemble and assemble the bus terminal 100 and the circuit board 2 without disassembling the entire bus 3, thereby significantly shortening the maintenance time and reducing the maintenance cost.

[0034] In one embodiment of the present invention, see Figure 1 , Figure 5 as well as Figure 6 The second bending arm 12 is provided with at least two welding legs 121 . The second bending arm 12 is provided with at least one welding leg 121 on two opposite sides along the length direction of the bending line of the first bending arm 11 and the second bending arm 12 .

[0035] In one embodiment, at least two welding feet 121 are protruding from the second bending arm 12, and these welding feet 121 are used to firmly weld the bus terminal 100 to the circuit board 2 to ensure the stability and reliability of the electrical connection. Specifically, the second bending arm 12 is provided with at least one welding foot 121 on each of the opposite sides along the length direction of the bending line of the first bending arm 11 and the second bending arm 12. This layout can effectively disperse the welding stress and avoid cracking or loosening of the welding point due to stress concentration. For example, two welding feet 121 can be respectively provided on both sides of the second bending arm 12 to form a symmetrical welding structure, thereby further enhancing the connection strength between the bus terminal 100 and the circuit board 2. This design is not only suitable for low-voltage relay matrices, but can also be widely used in other scenarios that require high-reliability electrical connections, such as charging piles, energy storage systems, etc.

[0036] The bus terminal 100 of the present invention significantly improves the connection strength and reliability between the bus terminal 100 and the circuit board 2 by providing at least two welding feet 121 on the second bending arm 12. This design can effectively disperse the welding stress and avoid cracking or loosening of the welding point due to stress concentration, thereby extending the service life of the product and reducing the maintenance cost caused by welding point failure. In addition, the symmetrical welding structure can also improve the stability of the bus terminal 100 on the circuit board 2 and reduce electrical connection problems caused by vibration or impact. For example, in charging pile applications, this design can ensure the stable operation of the bus terminal 100 under high current load and improve the overall reliability of the system.

[0037] In one embodiment of the present invention, see Figure 1 , Figure 5 as well as Figure 6 A first connecting chamfer 122 is formed between all the welding legs 121 and the second bending arm 12 , and each first connecting chamfer 122 connects a welding leg 121 and the second bending arm 12 .

[0038] In this embodiment, each solder leg 121 provided on the second bending arm 12 of the bus terminal 100 is provided with a first connection chamfer 122 between the second bending arm 12. This design processes a chamfer at the connection between the solder leg 121 and the second bending arm 12, so that the solder can more smoothly fill the connection area between the solder leg 121 and the circuit board 2 during welding, thereby improving the welding quality. Specifically, the first connection chamfer 122 can be a 45-degree angle or a rounded chamfer to ensure that the solder can fully wet the solder leg 121 and the pad of the circuit board 2. For example, in a specific embodiment, four solder legs 121 are provided on the second bending arm 12, and a 45-degree first connection chamfer 122 is processed between each solder leg 121 and the second bending arm 12, and the size of these chamfers can be adjusted according to the actual welding process requirements to ensure the reliability and consistency of welding. Through this design, the bus terminal 100 can be better combined with the circuit board 2 during the welding process, and a stable electrical connection can be maintained even under high current loads or harsh environments.

[0039] The design of the first connection chamfer 122 enables the solder to more smoothly fill the connection area between the solder foot 121 and the circuit board 2, reducing welding defects such as cold solder joints, insufficient solder, etc. This design not only improves the reliability of welding, but also enhances the mechanical strength of the solder joint, so that the bus terminal 100 can maintain a stable electrical connection under high current load or vibration environment, thereby extending the service life of the product.

[0040] In one embodiment of the present invention, see Figure 1 , Figure 5 as well as Figure 6 A first angle A is formed between the plane where the first bending arm 11 is located and the plane where the second bending arm 12 is located, and the range of the first angle A is 85° to 95°.

[0041] In one embodiment, the angle (first angle A) between the first bending arm 11 and the second bending arm 12 is precisely controlled within the range of 85° to 95°. This design optimizes the spatial layout and mechanical stability of the bus terminal 100 by adjusting the bending angle. In a specific implementation, the precise processing of this angle can be achieved by processes such as stamping and bending. For example, in one embodiment, the first angle A is designed to be 90°. This right-angle design enables the bus terminal 100 to better adapt to the common circuit board 2 layout, while providing good mechanical support and stability. In another embodiment, the first angle A is designed to be 85°. This slightly inclined angle can further optimize the contact area between the bus terminal 100 and the circuit board 2, reduce stress concentration, and improve the reliability of the connection. This design is not only suitable for the standard circuit board 2 layout, but can also be adjusted according to specific application requirements to meet different installation and use scenarios. The present invention significantly improves the mechanical stability and electrical connection performance of the bus terminal 100 by controlling the first angle A between the first bending arm 11 and the second bending arm 12 within the range of 85° to 95°. The design of this angle range enables the bus terminal 100 to maintain a stable structure under different installation conditions, thereby reducing deformation or damage caused by mechanical stress.

[0042] In one embodiment of the present invention, see Figure 1 , Figure 5 as well as Figure 6 A second connecting chamfer 112 is formed between the first bending arm 11 and the second bending arm 12 , and the second connecting chamfer 112 connects the first bending arm 11 and the second bending arm 12 .

[0043] In this embodiment, the first bending arm 11 and the second bending arm 12 are connected by a second connecting chamfer 112. This design makes the stress distribution of the bending part more uniform by processing the chamfer at the bending part, thereby improving the mechanical strength and reliability of the bus terminal 100. In specific implementation, the second connecting chamfer 112 can adopt a 45-degree or arc-shaped chamfer to ensure the strength and stability of the bending part. For example, the second connecting chamfer 112 between the first bending arm 11 and the second bending arm 12 of the bus terminal 100 is designed to be 45 degrees, and the size and angle of this chamfer can be adjusted according to the actual machining capacity and use requirements. Through this design, the stress concentration problem of the bus terminal 100 at the bending part is effectively alleviated, and the overall structural strength of the bus terminal 100 is improved, so that it can better withstand mechanical stress and electrical loads. The present invention significantly improves the mechanical strength and reliability of the bus terminal 100 by setting the second connecting chamfer 112 between the first bending arm 11 and the second bending arm 12. The design of the second connection chamfer 112 makes the stress distribution at the bend more uniform, reducing the risk of cracking or deformation at the bend due to stress concentration. By optimizing the angle and size of the second connection chamfer 112, the processing accuracy and assembly efficiency of the bus terminal 100 can be further improved, and the production cost can be reduced.

[0044] In one embodiment of the present invention, see Figure 7 The main body 1 has two second bending arms 12 , and the two second bending arms 12 are both connected to the first bending arm 11 ; and the two second bending arms 12 are both protrudingly provided with at least one welding foot 121 .

[0045] In one embodiment, the body 1 includes a first bending arm 11 and two second bending arms 12, and the two second bending arms 12 are respectively connected to the first bending arm 11. This structural design enables the bus terminal 100 to provide more stable support and more reliable electrical connection. Specifically, each second bending arm 12 is provided with at least one welding foot 121, and these welding feet 121 are used to firmly weld the bus terminal 100 to the circuit board 2. For example, two welding feet 121 can be provided on each second bending arm 12 to form a symmetrical welding structure, thereby further enhancing the connection strength between the bus terminal 100 and the circuit board 2. This design is not only suitable for low-voltage relay matrices, but can also be widely used in other scenarios that require high-reliability electrical connections, such as charging piles, energy storage systems, etc. Through this structural design, the bus terminal 100 can better adapt to different installation requirements and improve the overall stability and reliability of the system.

[0046] This design enables the bus terminal 100 to provide more stable support and reduce deformation or damage caused by mechanical stress. At the same time, the symmetrical welding structure can effectively disperse the welding stress and avoid cracking or loosening of the welding points due to stress concentration, thereby extending the service life of the product and reducing maintenance costs. For example, in a charging pile or energy storage system, this design can ensure the stable operation of the bus terminal 100 under high current load and improve the overall reliability of the system. In addition, by optimizing the number and layout of the welding feet 121, the assembly efficiency and welding quality of the bus terminal 100 can be further improved, so that it can perform well in various application scenarios and meet different usage requirements.

[0047] In one embodiment of the present invention, see Figure 1 , Figure 5 as well as Figure 6 The connecting portion 111a is a connecting hole, and an inner peripheral wall of the connecting hole is provided with an internal thread.

[0048] In this embodiment, the connection portion 111a of the bus terminal 100 is designed as a connection hole, and the inner peripheral wall of the connection hole is provided with an internal thread. This design enables the bus terminal 100 to be fixed to the bus bar 3 or other external structures by threaded connection, thereby achieving stable mechanical connection and reliable electrical connection. In the specific implementation process, the internal thread of the connection hole can select different thread specifications according to actual needs, such as metric thread or imperial thread, to adapt to different application scenarios. For example, in a specific embodiment, the internal thread of the connection hole can be designed as an M5 thread, which is used to cooperate with a standard M5 bolt to achieve the fixation of the bus terminal 100 and the bus bar 3. In addition, the diameter and depth of the connection hole can also be adjusted according to the thread specification and the size of the bus bar 3 to ensure the stability and reliability of the connection. Through this threaded connection method, the bus terminal 100 can be easily installed and disassembled, while providing sufficient mechanical strength and electrical contact performance. The threaded connection method not only provides stable mechanical fixation, but also ensures good electrical contact, reduces contact resistance, and improves the efficiency and stability of electrical connection. The threaded connection method also has the advantage of being easy to install and disassemble, making the maintenance and replacement of the bus terminal 100 more convenient and reducing maintenance costs. By selecting appropriate thread specifications, the connection performance of the bus terminal 100 can be further optimized to adapt to different application scenarios and usage requirements.

[0049] In one embodiment of the present invention, see Figure 1 , Figures 5 to 7 The first bending arm 11, the second bending arm 12 and the extension section 111 are all integrally formed structures.

[0050] In one embodiment, the first bending arm 11, the second bending arm 12 and the extension section 111 of the bus terminal 100 adopt an integrally formed structure. This design eliminates the potential weaknesses caused by connection methods such as welding or riveting in the traditional split structure by forming these three parts at one time during the manufacturing process. In the specific implementation process, metal stamping or casting processes can be used to achieve one-piece molding to ensure the integrity and strength of the structure. For example, using high-strength copper or copper alloy materials, an integrated bus terminal 100 having a first bending arm 11, a second bending arm 12 and an extension section 111 is manufactured by a precision stamping process. This manufacturing method not only improves production efficiency, but also ensures precise matching and good electrical connection between the various parts. In practical applications, this integrally formed bus terminal 100 can be widely used in various electrical equipment, such as charging piles, energy storage systems, and low-voltage relay matrices, etc., to provide stable and reliable electrical connections for these devices. The one-piece design eliminates the contact resistance and mechanical weaknesses that may be generated by connection methods such as welding or riveting in the traditional split structure, thereby ensuring the stability of the electrical connection and the robustness of the mechanical structure. For example, in charging piles or energy storage systems, this design can effectively reduce electrical faults caused by loose connections or poor contact, and improve the overall reliability and safety of the system. In addition, the one-piece molding structure also simplifies the production process, reduces production costs, and reduces errors in the assembly process, thereby improving production efficiency. This design performs well in practical applications, can meet the high performance requirements of various electrical equipment for the bus terminal 100, and has broad application prospects.

[0051] The present invention also provides a power distribution module 200, see Figures 1 to 4 The power distribution module 200 includes a circuit board 2, a bus bar 3 and a bus terminal 100. The specific structure of the subject 1 refers to the above embodiment. Since the power distribution module 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the bus terminal 100 connects the circuit board 2 and the bus bar 3.

[0052] In this embodiment, a power distribution module 200 proposed by the present invention integrates a circuit board 2, a bus bar 3 and a bus terminal 100, and the core of the power distribution module 200 is the unique design of the bus terminal 100. Specifically, the bus terminal 100 achieves a stable connection with the circuit board 2 and the bus bar 3 through the one-piece structure of the first bending arm 11, the second bending arm 12 and the extension section 111. In practical applications, the connecting portion 111a of the bus terminal 100 (such as the connecting hole and its internal thread) is used to make a mechanical and electrical connection with the bus bar 3, while the welding foot 121 on the second bending arm 12 ensures reliable welding with the circuit board 2. This design enables the power distribution module 200 to maintain stable electrical performance and mechanical stability under high current loads and complex environments.

[0053] In one embodiment of the present invention, see Figure 2 and Figure 3 The circuit board 2 is provided with a welding hole 2a, which is welded to the welding foot 121, and the bus bar 3 has a matching portion 31, which is detachably connected to the connecting portion 111a.

[0054] In one embodiment, welding holes 2a are provided on the circuit board 2, and these welding holes 2a form a welding connection with the welding feet 121 on the bus terminal 100. The welding holes 2a can be designed as circular or square holes that match the shape of the welding feet 121. After the welding feet 121 are inserted into the welding holes 2a, they are fixed by welding. At the same time, a matching portion 31 is provided on the busbar 3, and the matching portion 31 forms a detachable connection with the connecting portion 111a (such as the connecting hole and its internal thread) of the bus terminal 100. This design allows the busbar 3 and the bus terminal 100 to be quickly assembled and disassembled by means of threaded connection, further improving the flexibility and maintainability of the module. The matching portion 31 can be an external threaded column that matches the internal thread of the connecting hole, and the busbar 3 is fixedly connected to the bus terminal 100 by tightening the threaded column. This detachable connection method is not only convenient for installation and maintenance, but also can quickly replace damaged parts when necessary, reducing maintenance time and cost.
