Sealable terminal for rechargeable battery

摘要

A terminal for a battery has a mounting section and a contacting section. There is a torque ring between the mounting section and the contacting section. The mounting section is for holding the terminal within a battery cover, into which it preferably is injection molded. The terminal is a hollow body, which has an outer surface and an inner surface. At the contacting section, the outer surface is conically shaped. At the mounting section, the outer surface has at least one labyrinth ring forming a labyrinth. The inner surface comprises at least two sections. An upper section is essentially surrounded by the contacting section, and preferably has a conical shape. A lower section is essentially surrounded by the mounting section. The lower section preferably has a concave cross-sectional shape. Between the upper section and the lower section, there is an edge. The edge at the inner surface may be essentially surrounded by the torque ring at the outer surface.
