Patent ID: 8288986

Claim:
An electrical connection system, comprising: a socket extending longitudinally from a proximal socket end to a distal socket end, and including an inner socket-protrusion defining a longitudinally extending inner socket-aperture, an intermediate socket-protrusion concentrically extending around the inner socket-protrusion to form an intermediate socket-aperture therebetween, and an outer socket-protrusion concentrically extending around the intermediate socket-protrusion to form an outer socket-aperture therebetween, wherein each socket-aperture has an open distal end and an inward-facing electrical conductor that extends to a respective conductor-distance from the proximal end of the socket; and a plug extending longitudinally from a proximal plug end to a distal plug end, and including an inner plug-protrusion, an intermediate plug-protrusion concentrically extending around the inner plug-protrusion, and an outer plug-protrusion concentrically extending around the intermediate plug-protrusion, each plug-protrusion being configured with an outward-facing electrical conductor that extends a respective conductor-distance from the proximal end of the plug and is configured to be conformingly received within the respective socket-aperture by the inward-facing conductor of the respective socket-protrusion; wherein the sum of the conductor-distances of the outer plug-protrusion and the outer socket-protrusion is larger than the sum of the conductor-distances of the inner plug-protrusion and the inner socket-protrusion; wherein the sum of the conductor-distances of the inner plug-protrusion and the inner socket-protrusion is larger than the sum of the conductor-distances of the intermediate plug-protrusion and the intermediate socket-protrusion; wherein each socket-protrusion has an outward-facing electrical insulator that extends to an insulator-distance from the proximal end of the socket that is larger than the respective conductor-distance of that socket-protrusion; wherein the intermediate and outer plug-protrusions each have an inward-facing electrical insulator that extends to an insulator-distance from the proximal end of the plug that is larger than the respective conductor-distance of that plug-protrusion; and wherein each insulator extends radially to form an end-cap that covers the distal end of its respective socket-conductor.
