Connector and contact

A contact to be connected to a signal wire and a pair of ground wires formed on a board, the contact comprising:

• a ground terminal including
• a base that includes a first end and a second end,
• three first extension parts that extend from the first end of the base and include a first middle extension part and first side extension parts on sides of the first middle extension part, and
• three second extension parts that extend from the second end of the base and include a second middle extension part and second side extension parts on sides of the second middle extension part, the second extension parts being configured to contact a surface of the board and to be elastically bent when the contact is connected to the board;
• an insulating layer formed on a surface of the ground terminal;
• a signal line that is formed on the insulating layer and extends from an end of the first middle extension part to an end of the second middle extension part, wherein when the contact is connected to the board, the signal line on the second middle extension part is connected to the signal wire of the board and the second extension parts are elastically bent;
• and
• a pair of ground lines that are formed on the insulating layer, are connected to the ground terminal, and extend from ends of the first side extension parts to ends of the second side extension parts, wherein when the contact is connected to the board, the ground lines on the second side extension parts are connected to the ground wires of the board and the second extension parts are elastically bent.

A connector to be connected to a signal wire and a ground wire formed on a board, the connector comprising:

• a terminal including
• a base made of a conductive material,
• at least two first extension parts that extend from the base toward a first end of the connector, and
• at least two second extension parts that extend from the base toward a second end of the connector;
• an insulating layer formed on a surface of the terminal;
• a signal line that is formed on the insulating layer, is insulated from the terminal, and extends from an end of a first one of the first extension parts to an end of a first one of the second extension parts, the signal line being connected to the signal wire of the board when the connector is attached to the board;
• and
• a ground line that is formed on the insulating layer, is electrically connected to the terminal, and extends from an end of a second one of the first extension parts, which is adjacent to the first one of the first extension parts, to an end of a second one of the second extension parts, which is adjacent to the first one of the second extension parts, the ground line being connected to the ground wire of the board when the connector is attached to the board.
