Abstract

A connector with a sheet has a housing mated with another connector, a terminal secured to the housing and contacting another terminal on the other connector, and a sheet affixed to the housing. The sheet has a laminate structure which includes a soft magnetic layer having real parts of complex relative permeability at 100 MHz of from 20 to 45, and a conductive/dielectric layer having an electrical resistance of from 0.5 to 20 Ω·cm.

Claims

1. A connector, comprising:

a housing configured to be mated with another connector,

a terminal secured to the housing, the terminal including a contact configured to mate with a terminal of the another connector, and

a sheet affixed to the housing, wherein the sheet includes an electromagnetic interference suppressive sheet having a laminate structure of a soft magnetic layer and a conductive/dielectric layer, the soft magnetic layer including a soft magnetic powder and a resin being laminated on the conductive/dielectric layer, the conductive/dielectric layer including a conductive filler and a resin, the electrical resistance of the conductive/dielectric layer being from 0.5 to 20 Ω

·

cm, and the real parts of the complex relative permeability of the soft magnetic layer at 100 MHz being from 20 to 45.

2. A connector according to claim 1, wherein the sheet is affixed to an outer face of the housing so as to cover a portion directly above the contact.

3. A connector with a sheet according to claim 2, wherein the outer face is not a mating face or a mounting face.

4. A connector according claim 1, wherein the housing is made of a dielectric material, and a first dielectric constant of the conductive/dielectric layer is greater than an effective dielectric constant of the housing.

5. A connector according to claim 1, wherein the sheet is laminated so the conductive/dielectric layer is adjacent to the housing, and the soft magnetic layer is adjacent to the conductive/dielectric layer.

6. A connector according to claim 1, wherein the connector is a first connector, further comprising a second connector, the second connector being a cable connector.

7. A connector according to claim 1, wherein the soft magnetic powder used in the soft magnetic layer is a flaky soft magnetic metal powder, and the conductive filler used in the conductive/dielectric layer is conductive carbon fibers.
