The coupling device includes a body including a fastening portion configured to be coupled to a connector protrusion provided to protrude from the connector toward a first direction, and a rotating shaft connected to the case and the body, and the connector cover is configured to be coupled to the connector along a second direction.

One example device includes a first housing portion defining a first coupling surface; a second housing portion defining a second coupling surface, the first housing portion coupled to the second housing portion to form a housing, the first housing portion and the second housing portion defining an opening, the opening intersecting the first coupling surface and the second coupling surface; a first gasket positioned between the first coupling surface and the second coupling surface, the first gasket providing a first seal between the first housing portion and the second housing portion, a printed circuit board (“PCB”) disposed within the housing and coupled to at least one of the first or second housing portions; an electrical connector electrically coupled to the printed circuit board and positioned within the opening; and a second gasket positioned between the electrical connector and the housing, the second gasket providing a second seal between the electrical connector and the housing, wherein the first gasket is positioned to abut the second gasket and wherein compression of the first gasket between the first and second housing portions provides a third seal between the first gasket and the second gasket. Another example device includes a wireless field driver comprising a first antenna coil and an electrical current source electrically coupled to the first antenna coil; an electromagnetic field (“EMF”) sensor comprising a second antenna coil, wherein the EMF sensor is configured to generate a sensor signal indicative of a signal strength from the first antenna coil; a non-transitory computer-readable medium; and a processor in communication with the non-transitory computer-readable medium, the processor configured to execute processor-executable instructions stored in the non-transitory computer-readable medium to: cause the electrical current source to output a current to the first antenna coil to generate a first EMF; estimate the signal strength of the first EMF based on the sensor signal; and adjust the current to the first antenna coil based on an estimated signal strength of the first EMF to maintain a power characteristic and generate a second EMF at the first antenna coil.

A grounding device for maintaining a ground path between a component of a connector and an interface port when the grounding device flexes includes a sealing member configured to form a conductive ground path between a component of a connector and an interface port. The sealing member comprises a sealing portion that is configured to overlie a grounding portion toward a radial direction of the connector when the connector is assembled, and the sealing portion and the grounding portion of the sealing member are configured to flex when a force is applied to the sealing member so as to maintain a ground path between the component of the connector and the interface port when the sealing portion and the grounding portion flex and when a force is applied to the sealing member during operation of the connector.

Disclosed are methods and devices for testing downhole connector electrical systems and cable integrity during installation of a permanent completion, including a customized retrievable plug arm assembly connectable to the completion during RIH, the tool mimicking a retrievable ESP, but without motor, and can be employed with or without pressure isolation. Another method employs a slidable starpoint located within the downhole wet mate connector of the completion to provide continuous electrical contact between the phases when no retrievable assembly is in place. When a retrievable assembly is later put in place, the slidable starpoint is moved into a second position that no longer provides electrical contact between the phases. Another method uses fusible links installed between two conductors within the downhole electrical connector system of the completion to provide similar electrical contact between phases, the fusible link configured to melt away once motor current is sent through the conductors.

A liquid-cooled charging system for a vehicle is configured to dissipate heat generated during charging (including fast-charging) of an electrically-powered vehicle. The liquid-cooled charging system includes a charging assembly having an interface assembly configured to support a charging plug of a charging station and an energy transfer assembly configured to electrically couple the charging station to the battery of the vehicle during charging. Components of the charging assembly and energy transfer assembly also define a fluid circuit. A coolant system of the liquid-cooled charging system is fluidly connected to the fluid circuit, allowing coolant to flow through the fluid circuit to dissipate heat from the charging assembly components during charging of the vehicle.
