HOLLOW TYPE SECONDARY BATTERY

The present invention relate to a connector for a hollow core secondary battery, and in particular, to a connector of a hollow core secondary battery, which is configured to allow for a plurality of hollow core secondary batteries to be connected in parallel or series without any welding process and moreover to allow for hollows, which are formed to penetrate central portions of the secondary batteries, to be connected to each other. The present invention provides a connector for a hollow core secondary battery comprising a case having first and second openings formed through a sidewall of the case with a predetermined interval; a first connection portion provided at the first opening and coupled to a first terminal portion, which is provided at a side of the hollow core secondary battery, thereby connecting a hollow of the hollow core secondary battery to the first opening; a second connection portion provided at the second opening and coupled to a second terminal portion, which is provided at other side of the hollow core secondary battery, thereby connecting the hollow of the hollow core secondary battery to the second opening; and a conduit provided in the case to connect the first and second openings to each other.
