NOISE ABSORBER
Document Type and Number:
Japanese Patent JP2019186453
Kind Code:
A
Abstract:
To provide a noise absorber which can facilitate the process of winding multiple turns of a cable around a ferrite core.SOLUTION: A noise absorber 10 comprises: a rod-like ferrite core part 31 around which a cable 50 is directly or indirectly wound; and an outer peripheral ferrite part 32 covering the outer periphery of the ferrite core part 31. In this instance, the noise absorber 10 comprises: a bobbin part 20 having a cable wound part 21 around which the cable 50 is wound and a through-hole 22 formed inside the cable wound part; and a pair of ferrite parts 30 covering the bobbin part 20. Each of the pair of ferrite parts 30 may include: a rod-like part 31 which is inserted into the through-hole 22, while being equivalent to the ferrite core part 31 around which the cable 50 is indirectly wound; and an outer cylinder part 32 which is formed integrally with the rod-like part 31 and covers the bobbin part 20, while being equivalent to the outer peripheral ferrite part 32.SELECTED DRAWING: Figure 1
