In addition, the existing punching sealing structure works for a long time, and after the temperature of the product is raised too high, the effect is easy to lose efficacy, and oil immersion and leakage phenomena can occur. The existing punching sealing structure has the defects that one part of the structure is too simple, the sealing is not tight enough and the oil immersion and leakage phenomena occur easily, the other part of the structure is too complex, the requirement on the sealing structure production equipment is high, and the production cost is high.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) the sealing structure is not properly designed and is not properly matched with the punching structure, so that the efficacy is failed, the sealing is not tight, the sealing structure needs to be frequently replaced, and the production efficiency is greatly reduced

(2) The sealing structure has unstable performance, and the efficacy is easy to lose efficacy and oil immersion and leakage phenomena can occur after the product works for a long time and the temperature of the product rises too high.

(3) The structure is too complex, which results in high requirements for the production equipment of the sealing structure and, in fact, high production costs.
