  • Power connector ground polarization insert and connector used therewith
    Patent number: 6458000
    Abstract: The present invention provides a removable, “snap-in” ground polarization insert for a power connector that accommodates insertion of a corresponding ground polarization pin therein. The insert is molded from the same insulative material as the surrounding housing. The insert remains separate from the connector until assembly of the final product, enabling the user to determine the requisite combination of a proper insert configuration and a corresponding plug or receptacle that is currently available in the inventory. The ability to delay assembly of the connector and insert thereby allows use of the connector with pre-existing plugs and receptacles in view of available inventory and current customer demands.
