Abstract:
An isolating connector is disclosed for isolating the center conductor of a shielded cable from DC and low frequency AC potentials. The connector includes a generally tubular shell which is connected to the cable's shield and within which a connector pin is located for coupling to a female plug. A capacitance inside the shell is connected in series with the pin and the cable's inner conductor. Also inside the shell are two bleeder resistances, one connected in parallel with the capacitance and another connected in series between the shell and the connector pin. With this arrangement, any DC or low frequency AC potential appearing on the cable's inner conductor is isolated from the connector pin, and a discharge path is provided for the capacitance in the shell and any capacitance serially coupled with the cable's shield.
