Abstract
This invention discloses a water-coolable DC plug terminal and charging gun with improved cooling and sealing performance. The technical solution includes: a DC plug terminal body, the front end of which is an electrical contact portion and the rear end is a wiring portion. An insulating heat sink is provided between the electrical contact portion and the wiring portion of the DC plug terminal body. The insulating heat sink includes an insulating heat exchange layer on the DC plug terminal body formed by encapsulation and a set of heat sinks integrally formed on the insulating heat exchange layer. The front end of the insulating heat exchange layer has a first annular sealing groove, and the rear end has an integrally formed mounting flange. The rear end of the electrical contact portion of the DC plug terminal body has a second annular sealing groove.
