Abstract

Figs. 1-4 illustrate a reliable, high density contact connector that utilizes minimum insertion force. The connector contact housing is mounted in a rigid, fixed location and employs a handle attached to a mechanism that clamps the card in place. The printed circuit card is installed by sliding it down into place, closing the connector lever, clamping the card, and enabling the electrical connection. Mechanical alignment pins are provided to insure proper alignment between the card and connector. The pins are mounted in the rubber and pass through the printed circuit card when the clamp is closed. The flexible connector is held in alignment against these pins, providing the necessary alignment with the circuit board pattern.

No Insertion Force Connector

Figs. 1-4 illustrate a reliable, high density contact connector that utilizes minimum insertion force. The connector contact housing is mounted in a rigid, fixed location and employs a handle attached to a mechanism that clamps the card in place. The printed circuit card is installed by sliding it down into place, closing the connector lever, clamping the card, and enabling the electrical connection. Mechanical alignment pins are provided to insure proper alignment between the card and connector. The pins are mounted in the rubber and pass through the printed circuit card when the clamp is closed. The flexible connector is held in alignment against these pins, providing the necessary alignment with the circuit board pattern. Electrical contact is established via a flexible foil pattern, with gold plated contact points, that matches art-work on the printed circuit board. The "flex-contact" is wrapped around the end of the printed circuit card and held in place by a rubber pad attached to a closed clamping device. The termination of the foil pattern is soldered to wire-wrap pins mounted through the rigid connector mount. Minimum space is required for card replacement; the connector is held in place, and the cards are inserted from one axis. This conserves valuable real estate in the planar or mother board area. Clamping the card with silicon rubber provides a sound mechanical hold. Gold plating of each connection provides gold to gold e...
