COVER PLATE ASSEMBLY, MICROBATTERY, AND CAPSULE ENDOSCOPE

The present disclosure provides a cover plate assembly, a micro battery, and a capsule endoscope. The cover plate assembly includes a cover plate, an electrode post structure, and a sealing ring. The cover plate is configured to cover and seal the opening and in sealed cooperation with a side wall of the opening, thereby forming a seal between the cover plate and the housing. An outer peripheral side wall of the electrode post structure defines a sealing ring accommodation groove. The sealing ring is disposed on the outer peripheral side wall of the electrode post structure and accommodated within the sealing ring accommodation groove; the sealing ring is in sealed cooperation with the sealing ring accommodation groove, thereby enhancing the sealing performance between the sealing ring and the electrode post structure.
