  • Apparatus and method for preventing loss of electrical power in a portable electronic device
    Patent number: 7018736
    Abstract: An apparatus and method for preventing an interruption of electrical power to a portable electronic device, such as, for example, a call device, supplied by an internal battery when the portable electronic device is dropped or subjected to an external shock. A battery cover seals a battery compartment in which a negative battery terminal and a positive battery terminal, of a battery, are in contact with a respective compressible contact terminal and a fixed terminal. A battery fixing base plate, attached to an inner surface of the battery cover, includes a set flange that is inserted between a battery compartment wall to which one contact terminal is attached and an associated battery terminal in contact with the one contact terminal, thus providing a mechanism that prevents a longitudinal movement of the battery in the battery compartment.
