Abstract
An electrical connector for a medical instrument has a plug containing a plurality of pins in electrical communication with wires emanating from a shielded cable that is connected to a medical sensor detecting physiological data. The plug portion of the electrical connector substantially surrounds the connection of the pins with the cable in a plastic housing. When the plug is inserted in to a socket portion of the connector mounted to a medical instrument housing, the pins electrically communicate with a plurality of tubular sockets to communicate the signals to electronic devices in a medical instrument. Surface coatings on the connector are provided to shield the wire connections with the pins and tubular sockets from electromagnetic interference (EMI). A tubular shield is also provided in the medical instrument to shield the electrical connection between the internal cable and the tubular receptacles from EMI. The EMI shields on the connector and the EMI shielding on the connecting cables are all connected to a common ground. A significant reduction in EMI distortion of the sensor signals is achieved.
