Gas and liquid tight sealing structure of the metallic terminal of an enclosed type secondary cell |
摘要 |
<p>An enclosed type secondary-cell maintaining enclosed property and battery performance for a long period in a wide range of environments of use including high temperature, high humidity, and vibration is presented. A terminal pole 2 is composed of a current collector 2g, a flange 2b with a flat top surface, and a pole 2a formed on the flange upper surface 2bf projecting at right angle, a rotation arresting portion 18 of the terminal pole 2 is formed by the flange 2b and lower side of a lid 1, an annular packing 3 is disposed between the flange upper surface 2bf and lid 1 lower side so as to surround the pole 2a, an annular pressing spring 6 is pressed in from above the pole 2a, the annular packing 3 interposed between the flange upper surface 2bf and lid 1 lower side is compressed in the vertical direction by the elastic force of the annular pressing spring 6, the annular pressing spring 6 is stopped on the outer circumferential edge of the pole 2 at a position for sealing and fixing the terminal pole 2 in the lid 1, and thereby the battery jar 10 is enclosed.</p> |
