Noise reduction device and bus bar module

摘要

A noise reduction device includes a magnetic core and an elastically deformable elastic sheet. The magnetic core surrounds an outer periphery of an electric cable, and reduces noise emitted from the electric cable. The elastic sheet is wrapped around the electric cable so as to surround the electric cable, and is sandwiched between an inner peripheral surface of the magnetic core and an outer peripheral surface of the electric cable and elastically deformed.

主权项

1. A noise reduction device for use with a bus bar module having a holder, the noise reduction device comprising:
a magnetic core configured to surround an outer periphery of an electric cable; an elastic sheet configured to wrap around the electric cable so as to surround the electric cable, the elastic sheet being disposed between an inner peripheral surface of the magnetic core and an outer peripheral surface of the electric cable and elastically deformed, and at least a first portion of the elastic sheet overlaps a second portion of the elastic sheet; and a guide portion of the holder disposed between the elastic sheet and the electric cable.
