Connector with flexible beam providing uniform contact pressure

An electrical connector foe interconnecting a pair of generally parallel flat circuits, comprising:

• a generally flat molded dielectric housing adapter for mounting on a first flat circuit;
• and
• a plurality of terminals mounted on the housing and spaced there along, each said terminal including
• a base insert molded in the housing,
• a tail extending from one end of the base for connection to an appropriate conductor on said first flat circuit,
• a flexible cantilevered beam extending form an opposite end of the base and terminating in a U-shaped joint,
• a contact arm extending form the u-shaped joint back over the cantilevered beam and terminating in a contact portion for engaging an appropriate conductor on a second flat circuit, and
• said cantilevered beam including a first bowed portion nearer said base and projecting toward the first flat circuit and a second bowed portion nearer said U-shaped joint and projecting toward the second flat circuit, each bowed portion comprising straight lengths of the cantilevered beam meeting at an apex;
• wherein when said contact arm is pressed downwardly to compress the U-shaped joint, a moment of rotation will appearing in a forward length between the U-shaped joint and the second bowed portion, said moment of rotation will be countered by a stiffening of the second bowed portion and by resilience appearing in a rearward length of a beam between said second bowed portion and the base and the stiffening provided by the first bowed portion.
