The second connector includes a plug located at one end of the second connector. The sealing device includes a sealing ring. The slot includes a groove and a retaining ring. The inner wall of the groove includes a fixing section and a sealing section. The fixing section is used to fix the retaining ring, and the sealing section is used to place the sealing ring. The sealing section is located between the bottom of the groove and the fixing section. The original outer diameter of the sealing ring is larger than the inner diameter of the retaining ring, and the pressing inner diameter of the sealing ring is smaller than the inner diameter of the front section of the plug.

[0007] By adopting the above technical solution, the original outer diameter of the sealing ring is larger than the inner diameter of the retaining ring. The original outer diameter of the sealing ring refers to the outer diameter of the sealing ring in its relaxed state when it is not placed in the slot. In this way, the retaining ring prevents the sealing ring from falling out of the slot. When repairing the charging device, the second connector is pulled out from the first connector. Since the retaining ring prevents the sealing ring from falling out of the slot, the sealing ring is not easy to fall off and be lost from the first connector, thus ensuring the waterproof performance of the charging device and avoiding the safety hazards of leakage or short circuit. The pressing inner diameter of the sealing ring is smaller than the inner diameter of the front section on the plug. The pressing inner diameter of the sealing ring refers to the inner diameter of the sealing ring after it is placed in the sealing section and before it is pressed by the front section.

[0019] Optionally, a compressing section is arranged at a position of the ring groove close to the extruding section.

[0020] By adopting the above technical scheme, the blocking ring enters the ring groove and is clamped and fixed in the ring groove, and the outer side of the blocking ring is compressed by the compressing section, so that the shaking of the blocking ring in the ring groove is further prevented, the blocking effect of the blocking ring on the sealing ring is ensured, and the situation that the sealing ring falls off from the plug-in groove is further prevented.

[0021] Optionally, the plug-in block further comprises a top section, the top section, the front section, the transition section and the rear section are sequentially connected, an outer diameter of the rear section is greater than an outer diameter of the front section, and the plug-in groove further comprises a second groove, and the second groove is in communication with the first groove.
