The depth of the hole completely avoids the long-term operational difficulty of using the steel ball seal (the diameter of the sealed steel ball is very small, about 1 mm), and there is a technical problem that the sealing is not in place or too deep to cause poor sealing. 2)
- the sealing member with the hollow structure closed at the lower end has a lower requirement for the punching pressure than the solid sealing, and the hollow structure can fully exert the pressure generated by the interference fit, and is more favorable for the sealing member to be fully and uniformly pressed in the pressure. Inside the injection hole.
- the lower end ⁇ uses a spherical structure to make the punching operation easier.
- the use of a rod-type seal (cap or flat) with a cap has the advantages of easy manufacture and good sealing stability.
- the liquid injection hole adopts a countersunk hole, and the depression of the countersunk portion makes the limit flange of the sealing member difficult to be interfered by other components in the subsequent process of battery assembly, thereby ensuring the reliability of the sealing.
- the flange and the countersunk are tightly fitted to enable the double clamping function together with the sealing member located in the liquid injection hole to ensure the close fitting of the sealing member and the liquid injection hole, especially for the support portion.
- the flange In the case of a hollow structure, the flange is clamped and the outward elastic force of the hollow portion is increased.
- the elastic force is perpendicular to the sealing surface of the sealing member and the liquid injection hole, and the sealing ability of the sealing member can be effectively enhanced.
