Abstract:
1. A connector including: a plurality of contacts each having two contact portions adapted to contact a connecting object, a housing arranging and holding said contacts therein and having at its front portion a fitting opening into which said connecting object is inserted, and a pivoting member causing said contacts to be elastically deformed to push the contacts against said connecting object, wherein each of said contacts comprises a first piece having on one side of one end one of the two contact portions adapted to contact said connecting object and on one side of another end a pressure receiving portion adapted to be pushed by said pivoting member, a second piece having on one side of one end the remaining contact portion adapted to contact said connecting object and on one side of another end a connection portion adapted to be connected to a substrate, and a jointing portion for connecting said first and second pieces, and the contact portion of said first piece, said jointing portion, and said connection portion being arranged in the form of a crank, and wherein said contacts further comprise holding means permitting pushing portions of said pivoting member to pivotally move between said pressure receiving portions and said connection portions, wherein said pushing portions have oval shape, wherein said holding means comprises a projection provided on said pressure receiving portion of said first piece of at least every other contact to extend toward said connection portion, and a protrusion provided in the proximity of tip of the connection portion of said second piece of the at least every other contact to extend toward said pressure receiving portion, wherein said housing comprises a ceiling portion for covering the contact portions of said contacts and said pressure receiving portions, and said ceiling portion is provided with protection walls at least at both ends of said ceiling portion for preventing said ceiling portion from being raised when said connecting object is accidentally forced upwardly, and wherein said pivoting member comprises an actuating portion for pivotally moving the pivoting member, the pushing portions continuously arranged in the longitudinal direction of said pivoting member, and anchoring holes independent from one another for receiving therein said pressure receiving portions, respectively, said pivoting member being mounted on said housing so that said pushing portions are pivotally moved between said connection portions and said pressure receiving 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, and said actuating portion of the pivoting member is pivotally moved toward the fitting opening of said housing to bring the contact portions of said contacts into contact with said connecting object.
