Title:
ELECTRICAL CONNECTION STRUCTURE BETWEEN VIBRATION GENERATOR OF MOBILE RADIO EQUIPMENT AND PRINTED CIRCUIT BOARD
Document Type and Number:
Japanese Patent JP3689675
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrical connection structure between a vibration generator in a mobile radio equipment and a printed circuit board wherein soldering of lead wires is eliminated and vibration of the vibration generator transferred to the printed circuit board is absorbed.
SOLUTION: A conductive spiral spring member is provided between an electrode provided to the vibration generator and an electrode provided to the printed circuit board. The electrical connection between the vibration generator and printed circuit board reduces the electrical resistance with elasticity of a conductive spiral spring member and the vibration generated by the vibration generator is absorbed and not easily transferred to the circuit components mounted on the printed circuit board.
