An electrical connector having an active cooling system is described herein. The electrical connector can include a conductor having an electrically conductive pin, and a conductor receiver slidably coupled to the conductor. The conductor receiver can include a wall having an electrically conductive material forming a cavity into which the pin is received. The conductor receiver can also include an insulating sleeve mechanically coupled to the wall. The conductor receiver can further include a heat sink mechanically coupled to the insulating sleeve and a channel that collects heat absorbed by the heat sink. The heat collected by the channel can be vented outside the conductor receiver. Alternatively, the wall of the conductor receiver can be coupled to an insulator and have at least one aperture that vents heat from the cavity to the insulator.
