Figure 1 The projection relationship of this utility model is consistent in the up, down, left, right, front and back directions. The charging safety high voltage protection device for charging piles includes a bracket 11. Rotating seats 16 are arranged on the upper and lower sides of the bracket 11. An insulating ceramic cylinder 12 is arranged between the rotating seats 16. Insulating ceramic cylinder ends 13 are arranged on both sides of the insulating ceramic cylinder 12. The insulating ceramic cylinder ends 13 are rotatably connected to the rotating seats 16. A locking hole assembly is arranged between the rotating seats 16 and the insulating ceramic cylinder ends 13 to lock the insulating ceramic cylinder ends 13 to the rotating seats 16. Multiple protrusions 14 are arranged around the insulating ceramic cylinder ends 13. A fuse 21 is arranged on one side of the protrusion 14. The fuse 21 is connected to one side of the protrusion 14 through a wire terminal assembly.

[0022] Advantageously, the locking hole assembly includes a through hole 15 disposed in the rotating seat 16, an inner cavity 32 disposed in the end 13 of the insulating ceramic cylinder, and a plurality of inner holes 31 disposed on the inner side wall of the inner cavity 32. The inner holes 31 penetrate the end 13 of the insulating ceramic cylinder. After the through hole 15 and the inner hole 31 are aligned, fasteners pass through the inner hole 31 and the through hole 15, thereby realizing a fixed engagement connection between the end 13 of the insulating ceramic cylinder and the rotating seat 16.

[0023] Advantageously, the wire end assembly includes a wire end 19 disposed on one side of the protrusion 14, and contact plates 22 are detachably connected to both sides of the fuse 21. The wire end 19 is provided with a wire end groove 18 at the top and bottom. The contact plates 22 extend into the wire end grooves 18 and are locked. The contact plates 22 are locked and fixed to the vacuum tube inside the fuse 21 by means of fastener locking.
