Abstract: In a connector having a first and a second contact, the second contact has a portion covered with an insulating member. The insulating member causes contact timings of the first and the second contacts relative to a counterpart connector to be staggered from each other. The first and the second contacts are held by a housing which is attachable and detachable relative to the counterpart connector. It is preferable that the first and the second contacts have chamfered portions, respectively, and that one of the chamfered portions is covered with the foregoing insulating member.

Abstract: An electrical connector assembly (40) in which the elements (42, 44) providing electrical contact are separate from the element insuring sufficient normal contact force. The assembly is capable of operating at elevated temperatures by utilizing a stainless steel spring member (46) to provide the contact force, since stainless steel maintains its resiliency at high temperatures. The conducting elements (42, 44) are formed of a conductive material which maintains its conductivity over a wide range of temperatures. The assembly holds the conducting elements in a stack so that only a single spring member is required.

Abstract: In order to provide a single-sided, conductor-pinching connector suitable for connecting numerous conductors while reducing occupation space, it comprises an insulating body having a flat male projection extending on its mating side, contact pieces whose contact stems are laid on the opposite surfaces of the flat male projection of the insulating body, a shell enclosing the mating side of the insulating body, and a press plate to press the stripped ends of the insulated conductors against the conductor-pinching rear ends of the contact pieces. The conductor-pinching rear ends are bent at right angle relative to the contact stems of the contact pieces, and are directed in one and same direction. The arranging of upright conductor-pinching ends in one and same direction rather than the opposite directions permits reduction of the connector thickness to possible minimum.

Abstract: A quick connector includes a contact and a housing fitted thereon. The contact has a first contact piece, a second contact piece which cooperates with the first contact piece to hold a core wire of an electric wire, and leg portions which are electrically connected and mechanically fixed to a circuit board.
