Preferably, the positive and negative electrode terminal board of the conductive board and the aluminum-shell battery be connected through a screw thread and in groups.
Preferably, the conductive board and the positive and negative electrode terminal board of the aluminum-shell battery by T shape pin with connect eyelet welding
Connect and in groups.
Preferably, the positive and negative electrode terminal board of the conductive board and the aluminum-shell battery passes through pin and connecting hole interference
Be cooperatively connected and in groups.
The both ends of positive and negative electrode terminal board are lengthened and are exceeded collector plate by the present invention, and are respectively provided at least on the both ends exceeded
One connecting hole greatly reduces exploitation this avoid screw hole or the outer stud of production is directly opened on the positive and negative terminals of top cover
Cost；The area of positive and negative electrode terminal board increases, so that contact area increases between battery and conductive board, internal resistance is reduced；Pass through
Multiple connecting holes of positive and negative electrode terminal board setting, can take a variety of connection types, e.g., be bolted, screw connection, self tapping
Screw connection, pin connection or pin are welded with and connect, and are effectively guaranteed the reliability of connection, loosen to prevent connection.The present invention
Structure it is simple, take full advantage of threaded connection and the groups of respective advantage of welding.
