Title:
CURRENT INJECTION DEVICE
Document Type and Number:
Japanese Patent JP2021165702
Kind Code:
A
Abstract:
To provide a current injection device that can inject a noise current into a printed circuit board while keeping down attenuation of a communication signal of the printed circuit board.SOLUTION: A current injection device for injecting a noise current into a printed circuit board includes: an air-core coil formed in an arc shape; and a signal generator connected to the coil via an input line, for passing an AC current through the coil. The signal generator passes the AC current through the coil to generate a magnetic flux that changes in the center of the coil, and current induced by the change in the magnetic flux is injected as the noise current into a circuit on the printed circuit board located in an inner diameter direction of the coil in a non-contact manner.SELECTED DRAWING: Figure 2
