Connection structure for connecting batteries used in e.g. portable radio apparatus, has hook ring forming part allowing fixation of end of conducting part between round lid and negative electrode by being in contact with negative electrode

摘要

The structure has an anode (3) placed on a round cap (11) of a body (1), where the cap is fixed to support walls (12). The anode passes through a side of the cap. A protuberance for conducting electricity is placed near an edge of an end of a conducting part and tightened by the part. A negative electrode (4) is placed on the lid. A hook ring forming part is provided between another conducting part (8) and the electrode. The hook ring forming part allows fixation of an end of the latter conducting part between the lid and the electrode by being in contact with the electrode.
