This article describes a method of connecting together printed circuit (PC) boards to PC cards and flexible PC cables using a low-cost, zero- insertion-force (ZIF) connector. The basic connector can be operated by various methods to apply a contact force after insertion. Options described are mechanical cam-operated or sliding-wedge operated using a solenoid or memory alloy compression springs. In all methods, a contact wiping action occurs when the connector is closed. The flexible cable is continuous; only one component is needed to connect several connectors together. The design allows the flexible cable to be omitted where expedient. The connector will then accept a single card. In this case, the design will provide output pins on the connector. Fig.
