Electrical connecting member of assembling type and secondary battery pack containing the same

A connection member for electrically connecting a plurality of secondary battery cells arranged in the longitudinal direction and in the lateral direction in a physical contact fashion, when the secondary battery cells are mounted in a battery pack case, wherein

• the connection member comprises terminal connection parts for connecting the battery cells arranged in the longitudinal direction in series to each other, the terminal connection parts being connected to each other for achieving the connection in parallel between the battery cells arranged in the lateral direction, each terminal connection part including
• (a) a first contact part configured to correspond to the external shape of an electrode terminal of a lower battery cell, the first contact part contacting the electrode terminal of the lower battery cell at a region adjacent to the outer circumference of the electrode terminal, the first contact part having a predetermined width,
• (b) an elastic part tapered upward from the first contact part toward a central axis of each terminal connection part for elastically supporting the lower battery cell,
• (c) protruding coupling parts protruding upward from the elastic part to a predetermined height such that the protruding coupling parts are coupled to an electrode terminal of an upper battery cell, and
• (d) a second contact part disposed on the central axis of each terminal connection part such that the second contact part is depressed to a predetermined depth from the protruding coupling parts, the second contact part contacting the electrode terminal of the upper battery cell, and wherein
• the connection member is provided at one side thereof with a circuit connection terminal part.
