SIGNAL COUPLING DEVICE AND METHOD FOR FABRICATING THE SAME

摘要

In a signal coupling device for taking out or injecting a signal through a capacitor capacitively coupled to a power line, to prevent separation caused by thermal contraction stress during a molding operation from occurring at the interface between the capacitor (3) and an insulator (13) with which the capacitor (3) is encapsulated, the periphery surface of the capacitor (3) is previously coated with an insulating layer (11), and then the coated capacitor (3) and conductors (2a, 12a, 12b) connected to the capacitor (3) are encapsulated within the insulator (13) made of resin.
