Abstract

An electronic device includes a shielding member, an electric circuit, and a filter capacitor. The electric circuit has an output line and is arranged inside the shielding member. The filter capacitor is arranged outside the shielding member to be connected to the output line.

Claims

1. An electronic device, comprising:

a shielding member;

a terminal base main body attached to an outer side surface of the shielding member;

an electric circuit that has an output line and is arranged inside the shielding member; and

a filter capacitor that is embedded in the terminal base main body to be connected to the output line,

wherein the shielding member comprises a case.

2. The electronic device according to claim 1, further comprising a filter capacitor shielding member that shields the perimeter of the filter capacitor.

4. The electronic device according to claim 1 further comprising;

a fastening member fastening the terminal main body to the shielding member; and

an output terminal that is extended to the outside of the shielding member to be connected to the output line,

wherein a positive terminal of the filter capacitor is electrically connected to the output terminal, and

wherein a negative terminal of the filter capacitor is electrically connected to the fastening member.

5. The electronic device according to claim 4, wherein the negative terminal of the filter capacitor is electrically connected to the case to be earthed.

3. A power-supply unit, comprising:

a case, which serves as a shielding member;

a DC/DC converter that has an output line and is arranged inside the case;

a terminal base main body attached to an outer side surface of the case; and

a filter capacitor that is embedded in the terminal base main body to be connected to the output line.
