ABSTRACT:
A low insertion force arrangement for establishing a connection to a printed wiring board of the type including at least one printed wiring board terminal. The arrangement includes at least one connection spring including at least one actuator and at least one pivot point. A first embodiment includes an actuator engaging area located centrally on the spring between two pivot points which are located between a contact and a connection spring terminal. A second embodiment includes at least one connection spring including a pivot point centrally located on the spring between an actuator engaging area and a second pivot point both of which are located between a contact and a connection spring terminal. In both embodiments the contact is located at one end of each connection spring in alignment with a corresponding printed wiring board terminal. A connector body is provided including a groove adapted to receive and retain a printed wiring board. The connector body includes at least one cavity in which the connector spring is retained. An actuator engages the actuator engaging area to pivot the connection spring about its pivot point to engage the spring contacts with or disengage the spring contacts from the printed wiring board terminal.
