The present technology describes systems and methods for power coupling of a tractor-trailer system. The technology may include a robotic arm, an end effector, a coupling tool, and a tool resting rack. An electrical outlet on a trailer may be coupled with a tool under control of the end effector and positioning of the robotic arm. The end effector may include a housing, a motor, a clutch, and a drive shaft. A tool coupled to the end effector may include an electro-mechanical (EM) coupler. The EM coupler may include a housing, an electric plug, a lid lifter, a lead screw, and a servomotor.

An electrical connector assembly includes a connector housing defining a cavity in which an electrical busbar is disposed. The connector housing defines an opening to the cavity. The electrical connector assembly also includes a cover configured to enclose the cavity. The cover has an inlet port, an outlet port, and a coolant channel that is in fluidic communication with the inlet port and the outlet port. A portion of the cover is in intimate thermal contact with the electrical busbar.

A device for opening and closing a charging socket includes a flap element. Using a shaft, the flap element is movably disposed on a housing of the charging socket, and the shaft comprises a first notch and a second notch. The device further includes a retaining element. The retaining element is mechanically attached to the flap element and comprises a bolt. Using the shaft, the flap element is transferrable from a closed position to an opened position. In the closed position of the flap element, the bolt of the retaining element is latched in the first notch of the shaft. In the opened position of the flap element, the bolt of the retaining element is latched in the second notch of the shaft.

A connector assembly is configured to mate a first connector housing. The connector assembly includes a second connector, a second terminal, a second connector housing, an adaptor and a cover. The second connector housing accommodates the second terminal and includes an opening for providing access to the second terminal. The adaptor is coupled to the second connector housing. The cover is detachably mounted to the adaptor, wherein the adaptor is movable between a first position and a second position. In the first position the cover is separated from the opening of the second connector housing so as to provide access to the first terminal and the second terminal. In the second position the cover is closes the opening of the second connector housing.
