Connector

A connector detachably fitted with a flexible printed circuit board, including a plurality of contacts each having a contact portion to contact said flexible printed circuit board, a housing holding and fixing said contacts and having a fitting opening into which the flexible printed circuit board is inserted, locking members adapted to engage said flexible printed circuit board, and a pivoting member causing said contacts and said locking members to be elastically deformed,

• wherein said flexible printed circuit board is provided with anchoring portions, and said locking members each comprise a first piece having an engaging portion, having a tip, at one end adapted to engage said anchoring portion of the flexible printed circuit board, a pressure receiving portion, having a tip, at the other end adapted to be urged by said pivoting member, and a projection inwardly extending from said tip of said pressure receiving portion;
• a second piece having a connection portion at one end to be connected to a substrate;
• and a jointing fulcrum portion for connecting said first piece and the other end of said second piece;
• said locking members being installed on said housing, and wherein said [second pieces are void of parts at positions facing to said engaging portions of said first piece when said pivoting member is pivotally moved to bring said engaging portions of the locking members into engagement with said anchoring portions of said flexible printed circuit board] first piece of said locking member is arranged such that a length from said jointing fulcrum portion to said tip of said engaging portion is greater than a length of a portion of said second piece extending from said jointing fulcrum portion to an end thereof, to thereby prevent contact between said engaging portion and said end of said second piece when said locking member engages said flexible printed board.
