Cylindrical batteries

Abstract

The useful solution refers to a cylindrical battery consisting of a battery casing (11), battery terminals (12), and a corner sealing mechanism (13). The battery casing (11) has a chamber (111) and is made with an assembly hole (113) connected to the chamber (111). The battery terminals (12) extend through the assembly hole (113). One end of the battery terminals (12) is placed in the chamber (111). The corner sealing mechanism (13) extends through the assembly hole (113) and is placed between the battery casing (11) and the battery terminals (12). One end of the corner sealing mechanism (13) is placed in the chamber (111). The battery casing (11) is made with a rounded edge (112) at the corner where the mounting hole (113) intersects with the housing (111). The corner sealing mechanism (13) is compressible and deformable to seal the gap between the battery terminals (12) and the battery casing (11) at the rounded edge (112).
