Document Type and Number:
WIPO Patent Application WO/2020/199940
Kind Code:
A1
Abstract:
A top cover component (30) and a secondary cell (100). The top cover component (30) comprises a top cover plate (31), an electrode terminal, a fixing member (33), and a connecting member (34). The top cover plate (31) comprises an electrode extraction hole (311). The electrode terminal comprises a terminal plate (32) located at a side of the top cover plate (31) and covering the electrode extraction hole (311). The fixing member (33) at least partially encloses the terminal plate (32) so as to fix the terminal plate (32) at the fixing member (33). The connecting member (34) is isolated from the electrode terminal by means of the fixing member (33), and is connected to the top cover plate (31). The connecting member (34) comprises a body portion (341) provided with a first slot (341c) provided downwards along the top of the body portion (341). A part of the fixing member (33) is located in the first slot (341c). According to embodiments, the terminal plate (32) is firmly fixed onto the top cover plate (31) by means of the connecting member (34) and the fixing member (33), which reduces the possibility that the terminal plate (32) is separated from the top cover plate (31), thereby improving the safety of the structure of the secondary cell (100).
