ESD Spring for PCMCIA Cards

Title of disclosure: ESD/EMC Spring Clip for PCMCIA Adapter Cards

Disclosed is a mechanical clip designed to protect credit card sized adapters which conform to Personal Computer Memory Card International Association (PCMCIA) Standards. The disclosed clip design impedes direct contact of the PCMCIA card by users, thus eliminating the possibility of electro-static discharges (ESD) that could cause network system interruptions. The clip design also contains features to provide connection to frame ground so the clip seals gaps around the PCMCIA slot opening from electro-magnetic leakage. In summary, the design is compliant with Industry Standards for Electro-Static Discharge (ESD) and Electro-Magnetic Compatibility (EMC)
protection .

In the flat or blanked out state the spring clip is single piece of thin, precision sheet metal that is formed into a shape that possesses a number of beneficial features. In its finished or formed state the clip can be installed into a mechanical enclosure or standard adapter face
plate opening without the use of tools.

The clip consists of set of dimples (1) that provide retention of the spring clip in the opening of the mechanical enclosure or PCMCIA adapter face plate. Two horizontal flanges (2) provide an ESD discharge path to drain static energy onto the enclosure or face plate. Two vertical flanges
(3) provide an ESD discharge path to drain static energy onto the enclosure or face plate. The main body of...
