The connector includes: an axial member that is a cylindrical conductor; a central contact disposed inside along a central axis of the axial member; an insulating member interposed between the axial member and the central contact and which holds the central contact; a first flange and a second flange provided on an outer peripheral surface of the axial member; and a metal spring provided along an outer peripheral surface of the axial member. The metal spring includes: a C-shaped metal spring body; curved parts; elastic pieces that extend from the curved parts so as to face an outer peripheral surface of the metal spring body; inner protrusions provided on an inner peripheral surface of the metal spring body so as to protrude inside the metal spring body; and outer protrusions provided on outer peripheral surfaces of the elastic pieces so as to protrude outside the elastic pieces.

Resonance between outer conductors is prevented. A connector includes: a plurality of shield terminals each having an inner conductor surrounded by an outer conductor; and a resonance restriction member that restricts resonance between the shield terminals by connecting the outer conductors to each other and holding the outer conductors at the same potential. Resonance between the shield terminals can be prevented by preventing a potential difference from being generated between the outer conductors.

An apparatus for grounding a heatsink utilizing an EMC spring press-fit pin includes a printed circuit board, a logic chip, a heatsink, and a grounding member, where the grounding member includes an integrated spring and a first terminal pin at a first end of the grounding member.
