[0024] As Figure 2 And Figure 3As shown, the sealing assembly 2 comprises a sealing groove 21, which is arranged in the middle of one of the fixing rings 11 and is arranged close to the connecting groove 12. The other fixing ring 11 is fixedly connected with a sealing ring 22 in the middle. The sealing groove 21 corresponds to the position of the sealing ring 22. When the two fixing rings 11 are attached, the sealing ring 22 enters the middle of the sealing groove 21, so that the sealing ring 22 is tightly attached to the inner wall of the sealing groove 21. The gap between the two fixing rings 11 is sealed by the sealing ring 22. The above structure can effectively reduce the dust and small particles entering the connection position of the plug 1 and the socket 10, reduce the pollution of the dust to the contact points of the electrical appliances, reduce the damage and corrosion of the dust and small particles entering the gap of the connection position to the internal metal parts, and make the connector stable in operation in harsh environment.

The grooves 3 are arranged on one side of the connecting groove 12. The middle of the groove 3 is fixedly connected with a second spring 31. The end of the second spring 31 is fixedly connected with a buffer pad 32. When the plug 1 is connected with the socket 10, the buffer pad 32 first contacts the side wall of the corresponding fixing ring 11. When the two fixing rings 11 are continuously attached, the buffer pad 32 under pressure moves to the inside of the groove 3, and the second spring 31 elastically contracts.

During use, the metal rod 5 is isolated by the mesh cover 6, and when in use, the dust and impurities in the airflow are intercepted outside the mesh cover 6. The above structure can effectively block the dust and impurities in the external air from directly contacting the metal rod 5, effectively reducing the accumulation of dust and impurities adhering to the surface of the metal rod 5, and maintaining the cleanliness and heat dissipation effect of the surface of the metal rod 5.
