ABSTRACT:
A battery pack for a sterilizable instrument, such as a medical endoscope. The battery pack includes batteries removably positioned within an enclosure which mounts a first grouping of electrical contacts engaged with the battery contacts. The enclosure includes an outer end wall which sealingly encloses the first grouping of contacts. The outer end wall mounts a second grouping of electrical contacts which are normally resiliently maintained in a first position spaced from the contacts of the first grouping. The contacts of the second grouping sealingly penetrate through the outer end wall. When the battery pack is engaged on the instrument, the contacts of the second grouping engage third contacts on the instrument, causing the contacts of the second grouping to move into a second position where they directly engage contacts of the first grouping to provide electrical power to the instrument. When the battery pack is removed from the instrument, the contacts of the second grouping are resiliently returned to the first position, whereupon the batteries can be sterilized.
