COVER OF A POWER BATTERY AND METHOD OF MANUFACTURING THE SAME
First Claim
1. A manufacturing method of a cover of a power battery comprising the steps of:
- a preparing step, preparing a plate and two electrodes, wherein the plate has two through holes formed through and disposed on the plate at a spaced interval, the two electrodes are respectively a positive electrode and a negative electrode, and each electrode passes through a respective one of the two through holes; and
an injection-molding step, putting the plate and the two electrodes into a mold, wherein molten plastic materials form a sealing piece mounted between each electrode and the plate.

Abstract
A cover of a power battery has a plate, two electrodes, and two sealing pieces. The plate has two through holes disposed on the plate. The two electrodes are respectively engaged with the plate. The two sealing pieces are respectively mounted between the two electrodes and the plate, and are located between the two electrodes and the two through holes. Furthermore, the two sealing pieces are each formed integrally by an injection-molding step. The two sealing pieces allow the cover to isolate the outer space and the inner space of the power battery, and further to avoid air or liquid leakage. Moreover, the injection molding simplifies the assembly of the cover of a power battery, which makes the process of producing a cover of a power battery more efficient and more convenient. A manufacturing method of the cover of a power battery is also provided.
