Mounting structure for temperature detecting member in rechargeable battery

摘要

A temperature detection hole 12 having a bottom, which is sealed against the inside of the battery case 3 while being open to the outside, is formed in the battery case. The bottom wall 12a of the temperature detection hole is in contact with or in close proximity to the elements for electromotive force. Engaging hooks 14 are formed on lateral portions of the temperature detection hole 12 of the battery case 3, while a temperature sensor 13 is provided with elastically deformable engaging flanges 21. When the temperature sensor 13 is mounted removably in the temperature detection hole 12, the elastic restorative force of the engaging flanges 21 that are engaged in elastic deformation with the engaging hooks 14 is applied to the temperature sensor 13. The sensor end 13a of the temperature sensor 13 is thereby pressed against the bottom wall 12a of the temperature detection hole 12.
