[0017] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0018] One challenge in the application of existing aluminum-based flexible circuit boards is the connection method with other modules. Therefore, a terminal block is designed as an intermediate medium to connect the aluminum-based flexible circuit board with other components.
[0019] Specifically, such as Figs. 1 to 3 The new energy battery terminal includes a terminal 2 and a connecting piece conductor 5 disposed inside the terminal 2. The two ends of the connecting piece conductor 5 are respectively provided with a first pin 4 and a second pin 6, and the first pin 4 and the second pin 6 are made of aluminum metal.
[0020] The first pin 4 is coated with a chemical gold plating layer 7 on the surface for soldering connection of the circuit board module 1. By coating the chemical gold plating layer 7 on the first pin 4, it can be conveniently soldered with the copper-based circuit board or other circuit board modules 1, ensuring stable and reliable electrical connection between the circuit board module 1 and the aluminum-based conductor 3, reducing the problems of poor welding, short circuit or virtual welding that may occur in traditional welding, and the circuit board module 1 can be a copper-based circuit board, a PCB circuit board, etc. which can be connected with the first pin 4.
[0021] The second pin 6 is laser welded with an aluminum-based conductor 3 at one end, and the aluminum-based conductor 3 is an aluminum-based flexible circuit board.
[0022] As described above, the first pin 4 is coated with a chemical gold plating layer on the surface, which is soldered with the copper-based circuit board or other components, and the connection is stable and reliable. The chemical gold plating is only on the pin, and the gold plating area is small, saving cost; the second pin 6 is made of aluminum metal material, which can be laser welded with the aluminum-based circuit board, and the connection is also stable and firm, so that the terminal plays a role in facilitating the connection of the aluminum-based flexible circuit board with other modules and firm connection.
[0023] As shown in Fig. 3 , the length of the first pin 4 and the second pin 6 is 2mm, and the width is 1mm.
[0024] By setting the length of the first pin 4 and the second pin 6 to 2mm and the width to 1mm, it meets the standard of new energy industry battery, improving the safety of the battery in use.
[0025] As shown in Fig. 3 , a plurality of first pins 4 and second pins 6 are provided, and the spacing between adjacent two first pins 4 and second pins 6 is consistent.
[0026] By a plurality of first pins 4 and second pins 6, the connection between the circuit board module 1 and the aluminum-based conductor 3 is more stable.
[0027] As shown in Fig. 3 , the shape of the second pin 6 is stepped.
[0028] By setting the second pin 6 to be stepped, efficient electrical connection is achieved in limited space, which helps to reduce the volume of electronic equipment and improve space utilization.
[0029] As shown in Fig. 3 , the surface of the end of the second pin 6 laser welded with the aluminum-based conductor 3 is provided with glue for protection and reinforcement.
[0030] Through dispensing, the connection between the second pin 6 and the aluminum-based conductor 3 can be further strengthened, and the insulation and stability of the connection can be improved. Meanwhile, dispensing can also provide additional protection functions such as waterproofing and dustproofing, so as to ensure that the electronic device can work normally in harsh environments.
[0031] Working principle: when the aluminum-based conductor 3 needs to be connected with other modules, first, one end of the second pin 6 is aligned with the aluminum-based conductor 3, then the one end of the second pin 6 is connected with the aluminum-based conductor 3 by laser welding, and then glue is dispensed on the laser welding part to improve the insulation of the connection. Meanwhile, the thickness of the aluminum-based conductor 3 is 0.1 mm, and the thickness of the aluminum-based conductor 3 is set to 0.1 mm, so that the aluminum-based conductor 3 is more flexible when bending and is not prone to defects such as micro-cracks and open welding, thereby improving the reliability and service life of the product. In order to ensure the strength, the PIN pin in the joint can be thicker, but the laser welding area overlapping with the aluminum-based conductor 3 is as thin as possible, preferably within 0.1-0.2 mm. A chemical gold plating layer 7 is coated at the first pin 4, so that it can be conveniently crimped and welded with the circuit board module 1. The circuit board module 1 can be a copper-based circuit board, a PCB circuit board or other circuit board that can be connected with the first pin 4. Then, one end of the first pin 4 is soldered with the circuit board module 1. The tin soldering technology can realize high-precision welding, ensuring the stable and reliable electrical connection between the circuit board module 1 and the aluminum-based conductor 3, reducing problems such as poor welding, short circuit or virtual welding that may occur in traditional welding. Meanwhile, aluminum metal is used as the conductor material of the flexible circuit board assembly, replacing the traditional copper metal. The cost of aluminum metal is much lower than that of copper metal, and aluminum metal has a more abundant storage, which greatly reduces the production cost of the entire battery information acquisition system.
