A connector unit includes a first connector and a second connector. The first connector includes a first terminal fitting. The first terminal fitting includes a first connecting portion. The second connector includes a second terminal fitting, a housing and a shield shell. The housing includes an insertion hole, into which the first connecting portion is inserted, and a second connecting portion is arranged to be contactable with the first connecting portion in the insertion hole. The first terminal fitting integrally includes a resilient deforming portion for resiliently deforming the first connecting portion in a direction separating from the second connecting portion as contacting the second connecting portion. The first connecting portion is pressed against the second connecting portion and the second connecting portion is pressed against the shield shell via an insulating member by a resilient restoring force of the resilient deforming portion.

A high-voltage plug assembly includes a stationary first plug and a second plug that is movable along a connecting direction of the plugs. The plugs have mutually complementary plug contact elements. The second plug further has connection lines connected to its plug contact elements. An outlet direction of the connection lines extends perpendicular to the connecting direction. The second plug further has a position-securing element (PSE) that is displaceable along a displacement direction perpendicular to the connecting direction and that mechanically locks the plugs together when the plugs are connected while the PSE is displaced to a slide position. The PSE includes pairs of pins whose longitudinal axes are oriented in the PSE displacement direction and which are situated in pairs one behind the other in the PSE displacement direction. In the slide position in which the plugs are locked together, the pins respectively engage recesses of the plugs.

The present invention relates to a feedthrough (200) adapted for use within a passage (300). The feedthrough (300) has a body (202) having a first interface region (204) and a second interface region (206). The first interface region (204) comprises a platform region (214). At least one electrical conductor (212) extends through the body (202) and out of the body (202) to both the first interface region (204) and the second interface region (206). A printed circuit board (216) is attached to the platform region (214). At least one pin hole (234) defined by the printed circuit board (216) is configured to accept the at least one electrical conductor (212).

Provided is a liquid cooling system for a charging gun and a charging gun, relating to the technical field of charging guns. In the liquid cooling system for a charging gun, a head cooling assembly includes a head housing, a first head seal assembly, a second head seal assembly, and a third head seal assembly. The head housing is provided with a terminal port and a head inlet. The terminal passes through the terminal port and the connection end of the terminal is accommodated in the head housing. The head inlet is configured to enable a cable extend into the head housing to connect to the connection end of the terminal. The first head seal assembly is sealingly disposed at a joint between the connection end of the terminal and the cable. The second head seal assembly is sealingly disposed at the terminal port.
