The invention relates to the field of electric vehicles, and particularly provides a direct-current charging gun and charging pile. The invention aims to solve the problem that a user, when operating a current direct-current charging gun, needs to make round trips back and forth between a charging pile and a charging gun to stop charging, pull out the gun and return the gun, thereby degrading the user experience. For this purpose, the direct-current charging gun of the invention comprises an unlocking mechanism, a safety mechanism and a communication mechanism, wherein the safety mechanism is connected to the communication mechanism and the unlocking mechanism separately; the unlocking mechanism is used for locking when the direct-current charging gun is in use, and for unlocking when the direct-current charging gun is not in use; the communication mechanism is configured to interrupt a direct current in the charging gun when being triggered; and the safety mechanism is configured not to trigger the communication mechanism in an unarmed state and to lock the unlocking mechanism, and triggers the communication mechanism first and then unlocks the unlocking mechanism during arming. It can be avoided that the user makes round trips back and forth between the charging pile and the charging gun, thereby improving the user experience.
