| 1. A connector including a required number of contacts each having a contact portion adapted to contact a flexible board,
and a connection portion to be connected to a substrate, a housing having inserting holes for arranging and holding said contacts
inserted in said inserting holes and a fitting opening into which said flexible board is inserted, and a pivoting member mounted
on said housing on the opposite side of said fitting opening and causing said contacts to be elastically deformed so as to
push said contacts against said flexible board,
wherein said contacts consist of two kinds of first contacts and second contacts, and a first contact and a second contact
are arranged in one and the same inserting hole of said housing so that the contact portions of the first and second contacts
are facing each other,
wherein said first contacts each comprise the contact portion at one end and the connection portion at the other end, and
said second contacts each comprise a first piece having the contact portion at one end and a pressure receiving portion at
the other end, a second piece having the connection portion at an outer end, and an inclined elastic jointing-portion for
joining said first piece and the remaining end of said second piece,
wherein said pivoting member comprises an actuating portion for pivotally moving said pivoting member, pushing portions provided
continuously in the longitudinal direction of the pivoting member, and anchoring holes independent from one another for receiving
therein said pressure receiving portions, respectively, and said pushing portions are pivotally movable between said pressure
receiving portions and said connection portions of said contacts, during which pivotal movement, the axis of rotation of said
pushing portions is moved with their pivotal movement to achieve their compact rotation,
wherein said second contacts are each provided on said second piece with a fixing portion located substantially at the same
location as said elastic jointing-portion, thereby preventing said second contacts from being warped when said pivoting member
is being pivotally moved,
wherein said fixed portion extends outwardly from said second piece and spaced from said elastic jointing portion, and said
fixed portion gripping a bottom edge of the housing;
wherein said flexible board is provided with anchoring portions on both sides in its width direction, and locking members
each having engaging portion adapted to engage said anchoring portion are installed in said housing, and wherein said locking
members each comprise a first piece having said engaging portion at one end and a pressure receiving portion at the other
end, a second piece having a connection portion at an outer end, and an inclined elastic jointing-portion for joining said
first piece and the remaining end of said second piece, and each of said locking members are further provided on said second
piece with a fixing portion located substantially at the same location as said elastic jointing-portion; and
wherein said fixed portion of each of said locking members extends outwardly from said second piece of said each of said locking
members and spaced from said elastic jointing portion of said each of said locking members, and said fixed portion of said
each of said locking members gripping the bottom edge of the housing.
