Abstract
The design of the present invention compiles EMI protection of two formerly separated filtering devices (coil and ferrite beads) in one optimal packaging. It consists of a coil wound around a cylindrical tubular ferrite bead and welded at one end to the terminal receptacle fed through the ferrite bead. The signal is routed through the coil and then through the ferrite bead providing added filtering effect. The design provides further performance improvement and significant reduction of the packaging size. The filtering system of the present invention has a superior performance and efficiency in the 100 to 300 MHz range. The present invention provides minimum packaging size for required electrical and mechanical performance. The filter consisting of a coil and a ferrite bead is packaged in the contact portion (or nozzle area) of the connector, eliminating the necessity of packaging space in the connector housing. Providing only one locking hook improves side-to-side packaging performance for serviceable connectors and provides more reliable locking.
