Terminal and cable assembly and charging gun

A charging gun, comprising a terminal and cable assembly, wherein the terminal and cable assembly comprises a conductive terminal having a connecting end, a cooling chamber, a joint structure, and a liquid-cooled cable;

• wherein an end of the cooling chamber is hermetically sleeved on the conductive terminal, and the connecting end is located in the cooling chamber;
• the joint structure is connected hermetically to the other end of the cooling chamber;
• and
• the liquid-cooled cable comprises a cable conductor and a cable jacket, the cable jacket surrounds the cable conductor to form a cable cooling channel between the cable jacket and the cable conductor, an end of the cable conductor penetrates through the joint structure and is electrically connected to the connecting end, the cable jacket is hermetically connected to the joint structure, the cable cooling channel communicates with an interior of the cooling chamber via the joint structure, and a cooling medium is contained in the cable cooling channel and the cooling chamber.
