Patent ID: 7448893

Claim:
A connector with which a flexible printed circuit board is detachably fitted, including a required number of contacts each having a contact portion adapted to contact said flexible printed circuit board, and a housing having inserting holes for arranging and fixing said contacts therein and having a fitting opening for inserting said flexible printed circuit board therein, wherein the contacts of three kinds (contact A, contact B, and contact C) are inserted into the same inserting hole of said housing in a manner that the contact (the contact A) of one kind is inserted into the inserting hole from the side of the fitting opening and the remaining contacts (the contact B and the contact C) of the two kinds are inserted in parallel with each other into the inserting hole from the opposite side of the fitting opening, wherein said contact (the contact A) of the one kind and one (the contact C) of the remaining contacts of the two kinds are arranged in alignment with each other, and said contact (the contact A) of the one kind and the other contact (the contact B) of the two kinds are arranged to be staggered relative to each other, and wherein upon insertion of said flexible printed circuit board into said fitting opening, said flexible printed circuit board becomes into contact with said contacts (the contacts A) of the one kind and said other contacts (the contacts B) of the two kinds, wherein said contacts A each comprise at one end a connection portion and at the other end a contact portion adapted to contact said flexible printed circuit board, wherein said contacts B each comprise a first piece having at one end a contact portion adapted to contact said flexible printed circuit board and at the other end a connection portion to be connected to a substrate, a second piece having at one end an urging portion facing to said contact portion of said first piece to sandwich said flexible printed circuit board, and an elastic jointing portion for connecting the first piece and the other end of the second piece, and wherein said contacts C each comprise a first piece having at one end an urging portion facing to the contact portion of said contact A for embracing said flexible printed circuit board, a second piece being substantially parallel to the connection portion of said contact B and in contact with the lower surface of said inserting hole of said housing, and an elastic jointing portion for connecting the other end of the first piece and the second piece, and upon insertion of said flexible printed circuit board into said fitting opening, the flexible printed circuit board comes into contact with said contacts A and said contacts B.
