Abstract
A button battery is installed in a electronic device such as a signal transmitter and electrically connected by a terminal contacting a flat electrode terminal of the button battery. The terminal has a circular spring-contact member surrounding a terminal base, and the spring-contact member is connected to the terminal base by a pair of connecting portions. The terminal base is fixed to a substrate by soldering. Since the spring-contact member is formed in a circular shape, its length can be made sufficiently long to make its spring modulus low and to reduce spring-load imposed thereon, thereby avoiding plastic deformation of the spring-contact member. The terminal base soldered to the substrate is prevented from being peeled off by eliminating twisting force applied to the spring-contact member.

A terminal for electrically connecting a button battery, the terminal comprising:
- a terminal base for mounting the terminal on a substrate;
- a spring-contact member continuously encircling the terminal base, the spring contact member being adapted to resiliently contact a flat electrode terminal of the button battery;
- and
- connecting portions connecting the spring-contact member to the terminal base, wherein the terminal base, the spring-contact member and the connecting portions are integrally formed from a conductive flat plate.
A terminal for electrically connecting a button battery, the terminal comprising:
- a terminal base for mounting the terminal on a substrate;
- a spring-contact member continuously encircling the terminal base;
- connecting portions connecting the spring-contact member to the terminal base, the connecting portions being disposed symmetrically with respect to the terminal base;
- and
- contacting portions formed on the spring-contact member, so that the contacting portions resiliently contact a flat electrode terminal of the button battery, wherein the terminal base, the spring-contact member, the connecting portions and the contacting portions are all integrally formed from a conductive flat plate.
A terminal for electrically connecting a button battery, wherein the terminal comprises:
- a terminal base for mounting the terminal on a substrate;
- an annular spring-contact member, which continuously surrounds the terminal base, wherein the spring contact member is constructed and arranged to resiliently contact a flat electrode terminal of the button battery;
- and
- connecting portions, which connect the spring-contact member to the terminal base, wherein the terminal base, the spring-contact member and the connecting portions are integrally formed from a conductive flat plate.
