First Claim
Patent Images
1. A connector configured to engagingly mate with a power receptacle of a power source, the connector comprising:
- an electrically conductive shaft having a longitudinal axis, the shaft being moveable within the connector along the longitudinal axis and configured to contact the power receptacle;
an isolation ring protruding from an outer surface of the shaft, wherein the isolation ring comprises an electrically insulative material; and
an electrically conductive housing electrically coupled to a power supply, the housing comprising one or more electrically conductive fingers that are resiliently biased towards the longitudinal axis, wherein the shaft is moveable relative to the housing.

Abstract
A power supply connector including a spring loaded member that allows a connector to engage various power receptacles. This engagement of the connector and the power receptacle may reduce a contact resistance between the two components and heat dissipation associated therewith. Thus, the power supply connector reduces the risk of damage to the power supply due to heat dissipation in the power receptacle, power supply connector, or other portion of the power supply.

10. A method of activating a power supply to deliver power from a power source, the method comprising:
-
inserting a connector of the power supply into a power receptacle so that a force is applied to a shaft of the connector; in response to the force applied to the shaft of the connector, moving the shaft inward towards a body of the connector thereby causing a conducting finger of the connector to be moved from contact with an insulative portion of the shaft to contact a conductive portion of the shaft; transferring power from the power receptacle to the shaft; transferring power from the shaft to the conducting finger; and transferring power from the conducing finger to the power supply.

11. A method of disabling power delivered from a power source to a power supply, the method comprising:
-
engaging a connector portion of the power supply with a receptacle portion of the power source; changing a position of the connector so that a conducting finger of the connector is moved from contact with a conductive portion of the connector to contact an insulative portion of the connector; and blocking transfer of power from the power source to the power supply due to the contact of the conducting finger with the insulative portion of the connector, wherein the changing a position of the connector is caused by movement of a vehicle in which the power source is located.

12. A method of reducing contact resistance between a power receptacle and a power supply connector, the method comprising:
-
inserting the power supply connector into the power receptacle so that a shaft of the power supply connector contacts a portion of the power receptacle; engaging the power supply connector with the power receptacle so that the shaft is moved within the power supply connector; and creating an electrically conductive path through the power supply connector in response to movement of the shaft at least a predetermined distance within the power supply connector. - View Dependent Claims (13, 14)
