ABSTRACT:
A connector is disclosed for electrically interconnecting the conductive pins of an electrical component to a printed circuit board. The connector includes a plurality of conductive contacts mounted within a non-conductive housing. Each contact includes first and second upwardly extending arms spaced apart a distance sufficient to permit a conductive pin of the electical component to be freely mounted therebetween. The first arm of the contact is generally V-shaped in configuration and defines an intermediate projecting section, extending away from the second arm. A cammed closure is provided for exerting a force on the projecting section of the first arm in a direction towards the second arm. By this arrangement, after a conductive pin is mounted between the arms of the contact, the actuation of the cam causes the first arm of the contact to be moved into electrical contact with the conductive pin of the component. Further movement of the cam causes the contact point of the first arm to travel upwardly, along the conductive pin, wiping oxidation residue from the pin. In the preferred embodiment, the cam is movable to a locked position wherein the contact point of the first arm is located at a position on the conductive pin which has been wiped clean during the locking action.
