Patent ID: 7766694

Claim:
An electrical connector comprising: a housing made of insulator and provided with an opening through which a circuit board is inserted into the housing, a plurality of conductive contacts provided to be arranged in the housing to be positioned to correspond respectively to connecting terminals provided on the circuit board when the circuit board is inserted into the housing through the opening provided thereon, and an actuator provided to be rotatable to the housing for taking up a first station and a second station selectively and for engaging with the conductive contacts to cause each of the conductive contacts to come into press-contact with one of the connecting terminals corresponding thereto when the circuit board is inserted into the housing through the opening provided thereon and the actuator is shifted from the first station to the second station and to cause each of the conductive contacts to get out of press-contact with the corresponding one of the connecting terminals when the circuit board has been inserted into the housing and the actuator is shifted from the second station to the first station, wherein each of the conductive contacts has a fixed beam fixed to the housing, a movable beam provided thereon with a contacting projection for coming into contact with the corresponding one of the connecting terminals and an engaging portion for engaging with the actuator and a connecting strut for connecting a portion of the movable beam between the contacting projection and the engaging portion with the fixed beam to support the movable beam, wherein a first side edge portion of the connecting strut on the side of the contacting projection of the movable beam is perpendicular to the fixed beam and a second side edge portion of the connecting strut on the side of the engaging portion of the movable beam slants from the movable beam to the fixed beam so that a first end portion of the connecting strut connected with the fixed beam is wider in a direction along which the fixed beam elongates than a second end portion of the connecting strut connected with the movable beam, and wherein the movable beam swings with a fulcrum at the second end portion of the connecting strut connected with the movable beam when the engaging portion receives the pressure from the actuator whereby the connecting strut is prevented from inclining toward the contacting projection of the movable beam.
