[0033] To make the objectives, technical solutions, and advantages of this application more clear, the following embodiments of this application will be further described in detail with reference to the accompanying drawings. Obviously, the described embodiment is only one embodiment of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0035] like Figure 1-5 As shown, it is a schematic diagram of the overall structure of the laminated energy storage connector provided in an embodiment of the present application, including a first connector 10 and a second connector 20. The first connector 10 and the second connector 20 are usually installed together with the battery panel, and the first connector 10 and the second connector 20 can achieve conduction between the two battery panels after being plugged in. In this embodiment, in order to achieve conduction between the two battery panels, connection terminals are respectively provided on the first connector 10 and the second connector 20. Specifically, the first connector 10 includes a first fixing plate 11, and a first signal terminal assembly 12 and a first power terminal assembly 13 are provided on the first fixing plate 11. The first signal terminal assembly 12 is Multiple first signal female terminals distributed in an array are installed in the plug-in block 14, and the plug-in block 14 is arranged on the side of the first fixed plate 11 close to the second connector 20. The first power terminal assembly 13 is arranged on both sides of the plug-in block 14, and multiple first mounting portions 15 are provided on the first fixed plate 11. The first mounting portions 15 are columnar, passing through the first fixed plate 11 and are respectively located on both sides of the first fixed plate 11. The first power terminal assembly 13 is installed in the first mounting portion 15. In this embodiment, the first power terminal assembly 13 is a torsion spring terminal 131, which has the function of adaptive adjustment and can adapt to more models of male terminals.

[0036] The second connector 20 includes a second fixed plate 21, a second signal terminal assembly 22, and a second power terminal assembly 23. A frame 24 is provided on the second fixed plate 21. The second signal terminal assembly 23 is provided in the frame 24. The size of the frame 24 is adapted to the size of the plug-in block 14. The second signal terminal assembly 22 is a second signal male terminal. After the first connector 10 and the second connector 20 are assembled, the frame 24 is mated with the plug-in block 14. At the same time, the second signal terminal assembly 22 is mated with the first signal terminal assembly 12 to achieve signal connection. The second power terminal assembly 23 is a second power male terminal. A plurality of second mounting portions 25 are provided, each of which is cylindrical. A second power terminal is provided in each cylindrical second mounting portion 25. The size of the second mounting portion 25 is configured to accommodate the first mounting portion 15 for mating. After the first connector 10 and the second connector 20 are assembled, the second power male terminal is mated into the torsion spring terminal 131, and the first mounting portion 15 is mated into the second mounting portion 25. During the mating process of the first mounting portion 15 and the second mounting portion 25, the first mounting portion 15 not only serves as a guide but also serves as an insulating layer for the power terminal, further reducing impedance and signal attenuation. This results in lower energy loss and higher system efficiency during the charging and discharging process of the energy storage system, thereby optimizing the performance of the energy storage system. In this embodiment, the first signal terminal assembly 12, the first power terminal assembly 13, the second signal terminal assembly 22, and the torsion spring terminal 131 are all made of copper alloy with a silver-plated surface, having low contact resistance and good electrical conductivity.

[0037] like Figure 6-7As shown, in one embodiment of the present application, a guide post 30 is further provided between the first connector 10 and the second connector 20, and the guide post 30 passes through the first connector 10 and the second connector 20 to achieve a guiding function during the assembly process of the first connector 10 and the second connector 20. Specifically, a first guide hole 16 is provided on the first connector 10, and the number of the first guide holes 16 can be 2-4, which are respectively located at the four corners of the first connector 10, and a second guide hole 26 is provided on the second connector 20, and the number of the second guide holes 26 can be 2-4, which are respectively located at the four corners of the first connector 10. The four corners of 20 are described in detail. In this embodiment, two guide posts 30 are used as an example. The specific implementation methods of other numbers of guide posts 30 are basically the same and will not be repeated here. The two guide posts 30 are respectively located in the first guide holes 16 that are diagonally distributed. Normally, one end of the guide post 30 is first installed in the first guide hole 16. During the assembly process of the first connector 10 and the second connector 20, the end of the guide post 30 away from the first connector 10 is first inserted into the second guide hole 26 to provide a guide for the assembly of the first signal terminal assembly 12, the first power terminal assembly 13, the second signal terminal assembly 22 and the second power terminal assembly 23. Mounting grooves 17 are further provided at both ends of the first connector 10. The mounting grooves 17 are semi-closed mounting grooves, and a step screw 40 is provided in the mounting groove 17. The nut diameter of the step screw 40 is larger than the inner diameter of the mounting groove 17, and the diameter of the step surface of the step screw 40 is smaller than the inner diameter of the mounting groove 17. The step surface of the step screw 40 passes through the mounting groove 17 and has a certain movable gap in the mounting groove 17. After the first connector 10 is connected to the battery panel, it is fixed to the battery panel by the thread at the end of the step screw 40. Since there is a certain assembly gap between the step screw 40 and the mounting groove 17, the first connector 10 and the battery panel can adapt to larger installation tolerances and have better adaptability.
