Abstract
In a connector having at least one contact (3a,3b) held by an insulator (2a), a high-frequency current suppressor (4a,4b) is provided on the contact or the insulator. The high-frequency current suppressor serves to attenuate a high-frequency current flowing through the contact and having a frequency within a frequency band between several tens MHz and several GHz.
Claims25
A connector comprising:
- an insulator;
- at least one contact held by said insulator;
- and
- a high-frequency current suppressor for attenuating a high-frequency current flowing through said at least one contact and having a frequency within a frequency band between several tens MHz and several GHz, said high-frequency current suppressor being made of a magnetic substance of a magnetic composition comprising M, X and Y, where M is a metallic magnetic material consisting of Fe, Co, and/or Ni, X being element or elements other than M and Y, and Y being F, N, and/or O, said M—X—Y magnetic composition having a concentration of M in the composition so that said M—X—Y magnetic composition has a saturation magnetization of 35-80% of that of the metallic bulk of magnetic material comprising M alone, said magnetic composition having the maximum value μ″max of imaginary part μ″ of relative permeability in a frequency range of 0.1-10 gigahertz (GHz).
1 more element
A connector as claimed in clam 1, wherein said high-frequency current suppressor is deposited on said insulator so as to shield said at least one contact when said connector is connected to a mating connector.
