Abstract: An electrical connector adapted to be mated with a terminal block of the type having a plurality of terminal contact blades upstanding therefrom. The connector comprises a rigid body of insulating material having a plurality of apertures in each of which a contact slug is suspended by a coil spring for spring-biased electrical contact with a contact blade received in the aperture. A spring end tine projects through and is soldered to conductive zones on a printed circuit board carried by the connector body for electrical connection of the individual contact blades with electronic circuitry. A pair of clamps are pivotally mounted on opposite side edges of the connector body and coupled to a rotatable elliptical cam for selective movement between a retracted position and a position for embracing a terminal block.
