[0002] Copper-aluminum flexible connectors are suitable for use as flexible connections in various high-voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches, and related products such as automobiles and locomotives. They can improve conductivity, adjust installation errors between equipment, and also play a role in work compensation, facilitating testing and equipment maintenance. In addition, copper-aluminum flexible connectors have the advantages of being non-corrosive, having a long service life, good current carrying capacity, and good performance.

[0003] Traditional connection methods often rely on bolt fastening or simple mechanical clips. Under long-term vibration, temperature changes, and stress generated by battery charge and discharge cycles, these methods are prone to loosening or fatigue failure, resulting in increased connection resistance, affecting current transmission efficiency, and may even cause local overheating, accelerate battery aging, and reduce the safety of the battery module.

[0015] On the other side of the top of the connecting seat 2, there is a movable groove 3 25. The bottom of the movable groove 3 25 is slidably connected to a connecting plate 27. The top of the connecting plate 27 is fixedly connected to a connecting rod 26. The top of the connecting rod 26 extends through to the outside of the connecting seat 2 and is fixedly connected to the bottom of the lifting plate 3.

[0016] The front and rear sides of the lifting plate 3 are both provided with grooves 28.

[0017] The copper-aluminum sheet 1 has a slot 7 at the center of both sides. A card plate 8 is fixedly connected to the center of one side of the mounting groove 6. One side of the card plate 8 extends into the inside of the slot 7 and engages with the slot 7.

[0018] Both sides of the copper-aluminum sheet 1 are provided with slot 2 9 on one side of the top and bottom of slot 1 7. Slot 2 10 is fixedly connected to one side of the top and bottom of slot 1 8. The side of slot 2 10 away from slot 1 8 extends into the interior of slot 2 9 and engages with slot 2 9. A limiting groove 11 is provided in the center of one side of slot 1 8. A limiting plate 12 is fixedly connected to the center of the inner wall of slot 1 7. One side of the limiting plate 12 extends into the interior of the limiting groove 11 and engages with the limiting groove 11.

[0019] Positioning grooves 13 are provided at the four corners of the bottom of the copper-aluminum sheet 1. Movable grooves 14 are provided at the front and rear sides of the bottom of the mounting groove 6. An arc-shaped positioning block 16 is provided inside the movable groove 14. The top of the arc-shaped positioning block 16 extends into the interior of the positioning groove 13 and engages with the positioning groove 13. Sliding grooves 15 are provided inside the connecting seat 2 on both sides corresponding to the movable groove 14. Sliding blocks 17 are fixedly connected to both sides of the arc-shaped positioning block 16. The side of the sliding block 17 away from the arc-shaped positioning block 16 extends into the interior of the sliding groove 15 and slides in connection with the sliding groove 15.

[0020] Support grooves 18 are provided on both sides of the bottom of the arc-shaped positioning block 16. Support rods 19 are fixedly connected to both sides of the bottom of the movable groove 14. The top of the support rods 19 extends into the interior of the support grooves 18. A return spring 20 is sleeved on the outside of the support rods 19. The top and bottom of the return spring 20 are fixedly connected to the bottom of the arc-shaped positioning block 16 and the bottom of the movable groove 14, respectively.

[0021] Working principle: Place the copper-aluminum sheet 1 in the mounting groove 6 of the connector 2, aligning the first slot 7 with the first plate 8 and the second slot 9 with the second plate 10. Gently push the copper-aluminum sheet 1 so that the first plate 8 and the second plate 10 are respectively engaged in the first slot 7 and the second slot 9, achieving initial engagement and fixation. At the same time, the limiting plate 12 engages in the limiting groove 11, further enhancing the stability of the connection. After the copper-aluminum sheet 1 and the connector 2 are initially engaged, the arc-shaped positioning block 16, under the action of the return spring 20, moves automatically upward through the sliding of the slider 17 in the sliding groove 15 and engages in the positioning groove 13 at the bottom of the copper-aluminum sheet 1. The return spring 20... The elasticity ensures a tight engagement between the arc-shaped positioning block 16 and the positioning groove 13, effectively preventing the copper-aluminum sheet 1 from moving in the vertical direction. When further strengthening of the connection is required, the user can lift the lifting plate 3 upward through the pull groove 28. The lifting of the lifting plate 3 causes the fixing rod 5 to move upward, and the bottom of the fixing rod 5 disengages from the fixing groove 4. At the same time, the connecting rod 1 23 drives the movable block 22 to slide upward in the movable groove 21, compressing the reset spring 24. The connecting rod 26 moves upward with the lifting plate 3, and the connecting plate 27 slides in the movable groove 3 25. After confirming that the copper-aluminum sheet 1 and the connecting seat 2 are aligned correctly, the lifting plate 3 is released. The elastic force of the second return spring 24 pushes the movable block 22 and the first connecting rod 23 downward, and the fixed rod 5 re-clamps into the fixed groove 4, realizing the fixed connection between the lifting plate 3 and the connecting seat 2. At the same time, due to the descent of the lifting plate 3, the connecting plate 27 and the second connecting rod 26 also return to their original positions, further enhancing the stability of the connection. At this time, the copper-aluminum sheet 1 and the connecting seat 2 achieve a stable and reliable connection through various methods such as snap-fit, positioning block snap-fit, and lifting plate 3 fixation, which meets the high requirements of the new energy vehicle battery module for the connection structure.

[0022] In summary, this copper-aluminum flexible connection structure for the new energy vehicle battery module achieves multiple stable connections through the precise engagement of slots 7 and 9 on the copper-aluminum sheet 1 with slots 8 and 10 in the connecting seat 2, and the locking mechanism of the limiting plate 12 and the limiting groove 11. This design effectively avoids the loosening or fatigue failure problems of traditional bolt fastening or simple mechanical clips under long-term vibration, temperature changes, and battery charge-discharge cycle stress, significantly improving the stability and durability of the connection. The lifting plate 3, fixing rod 5, connecting rod 23, movable block 22, return spring 24, and connecting... The ingenious design of components such as the connecting plate 27 and the connecting rod 26 enables rapid assembly and disassembly of the connection structure. Users can complete the connection or disconnection simply by lifting the plate 3, which greatly simplifies the assembly process and improves maintenance convenience. The snap-fit ​​between the arc-shaped positioning block 16 and the positioning groove 13, as well as the sliding connection between the bottom slider 17 of the arc-shaped positioning block 16 and the sliding groove 15, makes the connection structure adjustable. This design not only improves the flexibility of the connection, but also enables the connection structure to adapt to the needs of battery modules of different sizes and shapes, enhancing its applicability and versatility.
