ELECTRONIC CIRCUIT UNIT HAVING CONNECTOR TERMINAL AND CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To prevent the conduction of noise to another signal or the frame ground of the signal through the common frame ground of a connector terminal. SOLUTION: An electronic circuit unit has a circuit board 10 on which a group of circuit elements are mounted, a plurality of connector terminals 41-47 used for outside connection, and a frame ground 30 provided in the circuit board 10. The frame ground 30 is arranged along the edge of the circuit board 10 in a state where the ground 30 is separated by a plurality of separating areas 31-37. The separating areas 31-37 are dispersedly arranged correspondingly to a plurality of connector terminals 41-47. In addition, at least part of the separating areas 31-37 is grounded through a limiting circuit 71. COPYRIGHT: (C)2006,JPO&NCIPI
