Anti-Static Connector Structure

To minimize existence of damaging potential difference between conductors in a cable at time of connection to an electronic circuit, cable terminals should be constructed using a material between conductors which has a sufficiently low resistivity that charge may quickly equalize between conductors.

Referring to the figure, a cable has an outer conductive shield 2 and an inner conductive wire 4 separated by a very high resistance insulating material 8. A cable terminal is connected to the end of the cable which is comprised of an outer conductive shield connector 10 and an inner conductive pin 12 separated by relatively low resistivity insulating material 14, e.g. plastic with a conductive powder additive.

Electrical resistance between pin 12 and shield connector 10 should remain high relative to impedance of the circuit to which it will be connected but low enough to quickly pass sufficient charge that a high voltage between cable conductors 10 and 12 is quickly reduced.

Multi-pin connectors can be similarly constructed to reduce chance of a high voltage from electrostatic charge on cable doing damage to an electronic circuit when the cable is plugged into the circuit.
