Title: SECONDARY BATTERY
Abstract:
A secondary battery, which relates to the technical field of energy storage device production, is disclosed. One of a first terminal assembly and a second terminal assembly (30) is electrically connected to a top cover (10) by means of a resistor (90), the other of the first terminal assembly and the second terminal assembly is provided to be electrically insulated from the top cover (10); the first terminal assembly comprises a flip piece (40) and a connection board (20), the flip piece (40) is attached to the connection board (20), the connection board (20) is fixed on the top cover (10) by means of a fixing member (70); in a default state, a first pole piece is electrically connected, by means of the flip piece (40), to the connection board (20), and a second pole piece is electrically connected to the second terminal assembly (30); and when pressure within the secondary battery exceeds a reference pressure, the flip piece (40) can be flipped to disconnect a conducting plate (50), thereby disconnecting the electrical connection state between the flip piece (40) and the first pole piece. Said secondary battery enables the connection board (20) to be fixedly connected to the top cover (10) by means of the fixing member (70), thereby not only solving the problem caused by penetrating nails , but also guaranteeing the reliability of the connection between the connection board (20) and the top cover (10).
