Abstract

A high-performance single barrel power connector for receiving electric power may be capable of receiving more than 330 W up to approximately 600 W of power. The V+ pin and V− pin may each be configured with a large plurality of contact points for connecting to a power plug. A connector body retaining the V+ pin and V− pin may configured with openings to expose more of the V+ pin and V− pin to air and allow the V+ pin and V− pin to extend out of the power connector for convective and conductive heat transfer. A shell having a high thermal conductivity may be connected to the V− pin and V− pin and further connected to a bracket for increased heat transfer away from the V+ and V− pins.
