Abstract

This is a card edge connector system for printed circuit cards utilizing relatively few component parts and featuring transverse card insertion, contact wipe, and a dust shield for environmental protection. The connector is a molded spring carrier employing beryllium copper or beryllium nickel spring contacts 1 and welded gold dots 2 for the contact points. The spring carrier 3 is attached to the printed circuit board member 4. The carrier 3 and spring contacts 1 are enclosed by a housing 5 which acts as a spring contacts separator, card guide, and environmental dust shield.

High Density Card Edge Connector

This is a card edge connector system for printed circuit cards utilizing relatively few component parts and featuring transverse card insertion, contact wipe, and a dust shield for environmental protection. The connector is a molded spring carrier employing beryllium copper or beryllium nickel spring contacts 1 and welded gold dots 2 for the contact points. The spring carrier 3 is attached to the printed circuit board member 4. The carrier 3 and spring contacts 1 are enclosed by a housing 5 which acts as a spring contacts separator, card guide, and environmental dust shield.

The spring contacts 1 are actuated by inserting a lift tool 6. The lift tool preferably is made of nylon or other appropriately strong material possessing slidable characteristics. The end portions la of the spring contacts 1 ride up the forward end of the lift tool 6 urging the spring contacts into an open state. The printed circuit card 7 can then be introduced between the spring contacts via transverse insertion or direct insertion. Once the printed circuit card 7 has been fully inserted, the lift tool 6 is removed. The resulting spring contact motion creates an electrical contact with the circuit conductive elements on both sides of the printed circuit card 7 with a contact wipe action being produced during the contact closure operation.
