Abstract
A plug-in electrical connector includes a filter assembly formed by a printed circuit board supporting surface mounted capacitors. One electrode of each capacitor is soldered to a peripheral track that is in electrical contact with the outer metal shell of the connector. The other electrode of each capacitor is soldered to respective conductive regions around plated-through apertures. Each aperture contains a socket soldered to it and extending through the board. The sockets have several spring wire elements that establish electrical connection with respective pins 11 that extend through the sockets. One end of each pin is crimped to a respective conductor, the other end of each pin serving to make electrical connection with a cooperating connector. Electrical interference on signals passing via the pins is dissipated to ground via the capacitors.
