An outer housing according to an aspect of the present disclosure has a first opening where the mating terminals are inserted along a first direction and a second opening for the wires to pass through along a second direction crossing the first direction. An inner housing is disposed inside the outer housing and holds the terminals therein. One of a first inner housing holder and a second inner housing holder is selectable as an inner housing holder to be attached to the second opening. The first inner housing holder includes a first mounting portion that is fitted into the second opening and a fixed leg that is fixed to a device to which a mating connector is attached. The second inner housing holder includes a second mounting portion fitted into the second opening.

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.

An electrical connector for coupling with a terminal conductive structure includes a terminal assembly that mates with a separate socket assembly in a rotational interface. The terminal assembly terminates in a conductive element, such as a tongue, configured for coupling with a conductive structure, such as a terminal block or power strip, for example. The separate socket assembly has a portion for receiving a conductor of a cable. The terminal assembly includes a pin that fits into a socket portion of the socket assembly for mating the terminal and socket assemblies to form a rotational interface. To secure the assemblies together an outer groove is formed on an outer surface of the terminal assembly and an inner groove is formed in an inner surface of the socket portion. An expandable ring is positioned in the outer groove and is compressed to fit inside of the outer groove for mating the terminal assembly pin and the socket portion. When the assemblies are mated, the grooves align for allowing the ring to decompress into at least part of the inner groove to secure the mated terminal and socket assemblies together in the rotational interface.
