Connector

A connector comprising:

• a plug contact having a conductive property, having a tubular shape, and including a recessed portion extending along a fitting axis;
• and
• an inner contact constituted of a projection that is inserted in the recessed portion and has an outer peripheral surface entirely covered with a conductive layer,
• wherein the inner contact has contacting portions making contact with the plug contact within the recessed portion and pressing portions situated in a rotational position different from the contacting portions about the fitting axis, and
• a part of a connection object of sheet type having a flexible conductor exposed on at least one surface of the connection object is sandwiched between the pressing portions and an inner surface of the recessed portion in a direction perpendicular to the fitting axis, the inner surface of the recessed portion makes contact with a top surface of the connection object, and the pressing portions make contact with a bottom surface of the connection object, whereby the plug contact is electrically connected to the flexible conductor directly when the flexible conductor is exposed on the top surface of the connection object, and the plug contact is electrically connected to the flexible conductor via the inner contact when the flexible conductor is exposed on the bottom surface of the connection object,
• wherein the projection includes:
• four first protrusion portions disposed at 90-degree intervals about the fitting axis, the four first protrusion portions protruding in directions perpendicular to the fitting axis;
• and
• four second protrusion portions disposed at 90-degree intervals about the fitting axis and each spaced from an adjacent one of the four first protrusion portions at a 45-degree interval about the fitting axis, the four second protrusion portions protruding in directions perpendicular to the fitting axis,
• the conductive layer covering a tip of each of the four first protrusion portions forms each of the contacting portions, and
• the conductive layer covering a tip of each of the four second protrusion portions forms each of the pressing portions.

• wherein the projection includes:
• three first protrusion portions disposed at 120-degree intervals about the fitting axis, the three first protrusion portions protruding in directions perpendicular to the fitting axis;
• and
• three second protrusion portions disposed at 120-degree intervals about the fitting axis and each spaced from an adjacent one of the three first protrusion portions at a 60-degree interval about the fitting axis, the three second protrusion portions protruding in directions perpendicular to the fitting axis,
• the conductive layer covering a tip of each of the three first protrusion portions forms each of the contacting portions, and
• the conductive layer covering a tip of each of the three second protrusion portions forms each of the pressing portions.
