The present invention relates to electrical connectors, and in particular to an electrical connector providing a means for establishing an automatic grounded termination point for the connector upon disconnection of the connector from an external signal source or receiving device. In the absence of an external electrical connection, the connector will be configured to establishing an automatic grounded termination point to eliminate the effects of stray capacitances, spurious extraneous signals and signal reflections on the circuitry connected to conductor. When coupled to an external connector, the connector ground connection will be broken to permit establishing a signal path for external circuitry. Also, a capacitive material can optionally be placed in series with the grounding resistive element assembly to block direct current to the resistive element in its grounded state that would otherwise overheat and damage the electrical resistor material.
