ABSTRACT:
A low insertion force connection arrangement for establishing a connection between at least two printed wiring boards, each board of the type including at least one printed wiring board terminal. The connection arrangement includes at least one connection spring having a pivot point facing away from the printed wiring boards and located between two actuator engaging areas. The actuator engaging areas face the printed wiring boards and are located between two contacts. The contacts are located at opposite ends of the connection spring facing and in alignment a corresponding terminal of each of the printed wiring boards. A connector body is provided including a plurality of grooves each adapted to receive and retain one of the printed wiring boards in alignment with the other boards, and a plurality of spring receiving cavities, each cavity enclosing a pair of connection springs and including a molded-in fulcrum opposite each spring's pivot point. Recesses are formed in opposite cavity walls proximate each of the molded-in fulcrum ends. Each of the connection springs is retained within a respective cavity by means of the spring fingers acting against the recesses. Actuators engage the actuator engaging areas to pivot each connection spring and disengage the spring from the terminals to thus permit insertion of the printed wiring boards within their respective grooves. The actuators are then disengaged from the actuator engaging areas to permit the springs to restore and engage the printed wiring board terminals.
