Abstract
An improved terminal apparatus is provided for electrical connections to a coin-shaped battery of a kind which may be employed in portable electronic equipment. The terminal apparatus includes a positive terminal plate for engaging a side surface (i.e., a positive electrode) of the coin-shaped battery and a negative terminal plate for engaging the bottom (i.e., a negative electrode) of the battery. The positive terminal plate is geometrically oriented so as to establish constant engagement with the side surface of the battery when placed in a battery holder. In a preferred embodiment of the invention, the positive terminal plate is made of a spring member and is curved toward the battery holder to elastically urge the side surface of the battery for constant engagement therewith. Alternatively, the positive terminal plate includes a hook portion engaging the side surface of the battery when placed in the battery holder. Further, the positive terminal plate has formed thereon a magnetized portion for attracting the side surface of the battery when placed in the battery holder for establishing constant engagement therewith.
