First Claim
Patent Images
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.

Abstract
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.

8. A manufacturing method for a noise reduction device for use with a bus bar module having a holder, the noise reduction device including a magnetic core configured to surround an electric cable, the method comprising:
-
providing the electric cable and a holder having a guide portion; wrapping an elastically deformable elastic sheet around the electric cable and the guide portion so that the elastic sheet surrounds the electric cable and the guide portion, the elastic sheet having a first portion and a second portion where the first portion overlaps the second portion; and elastically deforming the elastic sheet by attaching the magnetic core to the electric cable that is surrounded by the elastic sheet. - View Dependent Claims (9)
