Abstract

A combined action zero insertion force (CAZIF) connector is proposed, whose electrical contact-making springs are also used as hinges, about which the connector is opened and closed. This permits a rather compact overall connector design, offering, among others things, a low self-inductance as well as superior electrical shielding features and contamination protection. The CAZIF connector is schematically illustrated in the figures. Fig. 1 is a top view of the open connector, also indicating the contact in its closed position. Fig. 2 is a diagrammatic view of the connector, in which the above-mentioned shielding features are also indicated. Fig. 3 diagrammatically illustrates one possible latch design for this connector type. Contact springs 1, simultaneously serving as hinges 2 (Fig.

Combined Action Zero Insertion Force Connector

A combined action zero insertion force (CAZIF) connector is proposed, whose electrical contact-making springs are also used as hinges, about which the connector is opened and closed. This permits a rather compact overall connector design, offering, among others things, a low self-inductance as well as superior electrical shielding features and contamination protection. The CAZIF connector is schematically illustrated in the figures. Fig. 1 is a top view of the open connector, also indicating the contact in its closed position. Fig. 2 is a diagrammatic view of the connector, in which the above-mentioned shielding features are also indicated. Fig. 3 diagrammatically illustrates one possible latch design for this connector type. Contact springs 1, simultaneously serving as hinges 2 (Fig. 1), are held in a plastic block 3, so that they can be soldered to a printed circuit 4 (Fig. 2). Springs 1 keep the connector open, while a second printed circuit 5, arranged perpendicularly to the first, is inserted. Two plastic blocks 6, 7, molded around springs 1, are forced to close the connector. Springs 1 are fixed in these blocks adjacent to hinge 2. The pressure blocks 6, 7 exert on the electrical contacts ensures that printed circuits 4, 5 are reliably connected. Blocks 6, 7 serve to hold springs 1, so that, during contact making, contact wiper 8 is provided on facing pads of the inserted printed circuit 5. As indicated in Fig....
