[0027] As shown in Figure 2 And Figure 3 As shown in, the left and right ends of cap main body 1 are fixedly connected with fixed clamp 9 between inner walls to limit the position of waterproof layer a11 and waterproof layer b14, fixed groove 10 is formed in the inside of fixed clamp 9 to provide the installation position of waterproof layer a11 and waterproof layer b14.

[0028] The center of fixed clamp 9 is provided with another fixed sleeve inside, to limit the position of waterproof layer a11 and waterproof layer b14 by fixed sleeve and fixed clamp 9 together, the inside of fixed sleeve is provided with the same hole as fixed groove 10 and provides the installation position of waterproof layer a11 and waterproof layer b14 with fixed groove 10, fixed sleeve is welded on welding fixed boss 3.

[0029] As shown in Figure 3As shown, the upper end outer wall of the waterproof layer a11 is provided with an insulating layer 12, and the flashover outer wall of the insulating layer 12 is provided with a supporting layer 13 to keep the positions of the waterproof layer a11 and the waterproof layer b14 in a flush state. The waterproof layer a11 and the waterproof layer b14 are both made of nylon material, and the insulating layer 12 is mesh-shaped and attached to the mesh holes of the waterproof layer a11.

[0030] The insulating layer 12 reduces the generation of static electricity and prevents water or moisture from penetrating the waterproof layer a11. The waterproof layer a11 and the waterproof layer b14 made of nylon material are not water-absorbing and have strong hydrophobicity, which can avoid the penetration of water.

[0031] As shown in Figure 2 The waterproof layer a11, the insulating layer 12, the supporting layer 13, and the waterproof layer b14 are fixedly connected by a waterproof adhesive, and the fixed clamp 9 and the cap body 1 are fixedly connected by welding.

The welding method can stably limit the position of the fixed clamp 9 clamping the waterproof layer a11.

[0033] As shown in Figure 1 and Figure 2 The upper end outer wall of the clamping plate 2 is fixedly connected with a boss 3, the lower end outer wall of the explosion-proof sheet 4 is provided with a clamping groove 7 near the left and right sides, the left and right ends of the connecting aluminum sheet 5 are fixedly connected with a clamping tooth a6 which is upwardly clamped in the clamping groove 7 to limit the position of the connecting aluminum sheet 5, the left and right inner walls of the cap body 1 are fixedly connected with a clamping tooth b8 to limit the position of the clamping plate 2, the left and right sides of the clamping plate 2 are in a rolled edge shape to clamp and limit the position of the boss 3, and the lower end outer wall of the connecting aluminum sheet 5 is clamped with a prompt mark to prompt that the current cap body 1 is an S-shaped welding cap.

[0034] The combination of the clamping plate 2, the boss 3, and the clamping tooth b8 forms a relatively stable support structure, ensuring the stability of the internal components of the battery during operation. The clamping plate 2 in a rolled edge shape can effectively clamp the boss 3 to prevent displacement. The clamping tooth a6 of the connecting aluminum sheet 5 cooperates with the clamping groove 7 of the explosion-proof sheet 4 to achieve more reliable fixation through elastic cooperation, avoiding instability. The combination of the clamping tooth b8 and the clamping plate 2 ensures that the entire structure can still maintain the stability of the internal components of the battery when impacted.

[0035] The principle of the embodiment is that the cap body 1 and the clamping plate 2 work together to ensure that the components inside the battery are fixed and effectively sealed. In the event of a malfunction inside the battery, such as overheating or excessive pressure, the explosion-proof sheet 4 can quickly respond by rupturing or releasing pressure to reduce the risk, protecting the battery and its surroundings. The connection aluminum sheet 5 ensures that the battery's electrical energy is safely and effectively transmitted to external devices while maintaining the integrity of the entire structure. After the cap body 1 is welded and assembled into the battery, the waterproof layer a11 and the waterproof layer b14 double-block the moisture and humidity from entering the battery through the internal gap of the cap body 1, preventing the battery from being corroded by moisture and humidity, which can cause short circuits.
