[0002] Battery production refers to the process of transforming raw materials into battery products with energy storage and power supply capabilities through a series of industrial processes and technologies. This process covers the entire chain from raw material preparation, electrode manufacturing, battery assembly to performance testing, involving interdisciplinary technologies such as chemistry, materials, mechanics, and electronics. Battery tabs are key conductive components in batteries that connect electrodes to external circuits. Their core function is to realize the input and output of electrical energy, while ensuring a safe and stable connection between the battery's internal and external circuits.

[0003] Currently, most battery terminals are insulated by spraying an insulating coating. However, the thin insulating layer is easily damaged by impacts. During battery assembly, transportation, or use, friction between the terminals and the casing or other components can cause the coating to peel off, exposing the conductive surface and posing a short circuit risk, thus reducing the safety of the battery during use. To solve these technical problems, it is necessary to design a battery terminal insulation module. Utility Model Content

It solves the problem that most existing battery tab insulation methods involve spraying an insulating coating on the tabs, which can cause the coating to peel off during battery assembly, transportation or use due to friction between the tabs and the casing or other components, exposing the conductive surface, causing a short circuit risk and reducing battery safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating module for a battery tab, comprising a module body, a receiving groove formed on the surface of the module body, a through hole formed on the inner wall of the receiving groove, a limiting structure integrally formed on the inner wall of the through hole, and a guide strip integrally formed on the inner wall of the receiving groove.

[0006] Preferably, there are two guide strips, which are located on both sides of the inner wall of the receiving groove.

[0007] Preferably, the outer surface of the module body is provided with an outer rounded corner, and the inner wall of the receiving groove is provided with an inner rounded corner.

[0008] Preferably, the inner cavity of the receiving groove is provided with a limiting plate, one side of which extends through to the outside of the module body and is connected to a connecting block.

[0009] Preferably, the inner wall of the receiving groove is provided with a slot, and one side of the limiting plate extends into the inner cavity of the slot.

[0010] Preferably, a damping sleeve is provided at the connection between the limiting plate and the module body, and the outer surface of the damping sleeve is fixedly connected to the module body.

[0011] Preferably, the surface of the module body is provided with a positioning groove, and a positioning rod is fixedly connected to the surface of the connecting block, with one end of the positioning rod extending into the inner cavity of the positioning groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model improves the safety of the wide-blade battery and reduces the possibility of short circuit by setting up a module body and receiving slot through holes, separating the tabs of the wide-blade battery with insulating material. The limiting structure can stably fix the tabs of the wide-blade battery in pairs, avoiding external impact from affecting the tab connection. The integrated structure design makes the installation and use process simple, greatly saving production and labor costs.

[0014] 2. The outer rounded corners of this utility model reduce the stress concentration coefficient at the edge of the module body, preventing the module body from breaking during assembly or drops, and extending the service life of the module body.

[0021] Please see Figures 1-5An insulating module for battery tabs includes a module body 1, a receiving groove 2 on the surface of the module body 1, a through hole 3 on the inner wall of the receiving groove 2, a limiting structure 4 integrally formed on the inner wall of the through hole 3, and a guide strip 5 integrally formed on the inner wall of the receiving groove 2. By setting the module body 1, the receiving groove 2 and the through hole 3, the tabs of the wide-blade battery are separated by insulating material, which improves the safety of the wide-blade battery and reduces the possibility of short circuit. The limiting structure 4 can stably fix the tabs of the wide-blade battery in pairs, avoiding external impact from affecting the tab connection. The integrated structure design simplifies the installation and use process, and greatly saves production and labor costs.

[0022] Please see Figures 1-3 There are two guide bars 5, which are located on both sides of the inner wall of the receiving groove 2. The two guide bars 5 form a symmetrical constraint to ensure that there is no axial deviation when the electrode is inserted, and to avoid the electrode edge from rubbing against the inner wall of the module due to offset, thereby reducing the risk of insulation layer wear.

[0023] Please see Figure 1 The outer surface of the module body 1 is provided with outer rounded corners, and the inner wall of the receiving groove 2 is provided with inner rounded corners. The outer rounded corners reduce the stress concentration coefficient at the edge of the module body 1, preventing the module body 1 from breaking during assembly or drop, and extending the service life of the module body 1. The inner rounded corners prevent the electrode tab from being scratched by sharp edges when inserted, keeping the electrode tab surface intact.

[0024] Please see Figures 4-5 The inner cavity of the receiving groove 2 is provided with a limiting plate 6. One side of the limiting plate 6 extends to the outside of the module body 1 and is connected to a connecting block 7. By setting the limiting plate 6, it can fit and limit the battery tabs, forming a double constraint with the limiting structure 4. By setting the connecting block 7, moving the connecting block 7 drives the limiting plate 6 to move, which facilitates the disassembly of the limiting plate 6 and the disassembly and recycling of the insulation module.

[0025] Please see Figure 5 The inner wall of the receiving groove 2 is provided with a slot 8, and one side of the limiting plate 6 extends into the inner cavity of the slot 8. By setting the slot 8, it is convenient to engage with the limiting plate 6, which improves the stability of the limiting plate 6 after installation.

[0026] Please see Figure 5 A damping sleeve 9 is provided at the connection between the limiting plate 6 and the module body 1. The outer surface of the damping sleeve 9 is fixedly connected to the module body 1. The damping sleeve 9 is made of high-damping silicone rubber and wraps around the connection area between the limiting plate 6 and the module body 1 to provide damping support for the limiting plate 6, thereby preventing the limiting plate 6 from shaking and displacing during use and improving the stability of the installation of the limiting plate 6.

[0027] Please see Figure 5The module body 1 has a positioning groove 10 on its surface, and a positioning rod 11 is fixedly connected to the surface of the connecting block 7. One end of the positioning rod 11 extends into the inner cavity of the positioning groove 10. By setting the positioning groove 10 and the positioning rod 11, the connecting block 7 is positioned, which makes it easier for the connecting block 7 to fit tightly with the module body 1, facilitates the quick installation of the connecting block 7, and improves the stability of the installation of the connecting block 7.

[0028] In use, the module body 1 is fitted onto the surface of the battery tabs, the battery tabs are placed in the inner cavity of the receiving groove 2, the limiting structure 4 limits the battery tabs and restricts them within the inner cavity of the receiving groove 2, the limiting plate 6 passes through the damping sleeve 9 and is inserted into the inner cavity of the slot 8 to position and install the limiting plate 6, the positioning rod 11 is inserted into the inner cavity of the positioning groove 10 to position and install the connecting block 7, the limiting plate 6 limits the battery tabs, the damping sleeve 9 covers the connection area between the limiting plate 6 and the module body 1 to provide damping support for the limiting plate 6 and prevent the limiting plate 6 from shaking or displacing during use.

[0029] In summary, this battery tab insulation module, through its main body 1, receiving groove 2, through hole 3, limiting structure 4, and guide strip 5, solves the problem that most existing battery tab insulation methods involve spraying an insulating coating on the tab. However, during battery assembly, transportation, or use, friction between the tab and the casing or other components can cause the coating to peel off, exposing the conductive surface, leading to a short circuit risk and reducing battery safety.
