IPC: H05K5/02
Filed: 1989-06-22
Abstract: PURPOSE:To reduce in size an electronic apparatus by providing a metal plate inside of a sheath member or therein, and providing a role of reinforcing the member and a role as a contact member at the plate. CONSTITUTION:Since metal plates 16, 18 are insert molded in a holder 12, the strength of the holder 12 can be sufficiently held. Since the protrusions 16B, 18B of the plates 16, 18 are brought into contact with the terminals 14A, 14B of a battery 14, the plates 16, 18 constitute a circuit between the battery 14 and an electronic board 20 to electrically connect them. Accordingly, it is not necessary to mount reinforcing metal plate in the holder as in the prior art. Since a pin for electrically connecting the battery 14 to the board 20 is eliminated, the holder can be reduced in thickness. Thus, an electronic apparatus can be reduced in size.
