Abstract
A ground conductor and a signal conductor are provided in an insulating magnetic body respectively. The insulating magnetic body is a compound member that combines ferromagnetic metal particles and an insulating resin. A signal transmission element, a connector or a circuit board with high frequency stopping and low pass characteristics which will ensure reliable absorption of high frequency components in the high frequency range, can be provided.
Claims7
A connector for suppressing signal noise components above 1 GHz, comprising:
- an insulating magnetic body having an insulating resistance of 10.sup.9 ohms or more and including a compound member in which ferromagnetic metal particles and an insulating resin are mixed;
- a cylindrically shaped signal conductor having a tensile property and penetrating and being in contact with said insulating magnetic body;
- a cylindrically shaped ground conductor mounted on and being in contact with said insulating magnetic body and having each of two ends formed as one of a cable connector and a circuit system connector wherein said ground conductor covers said insulating magnetic body.
