By arranging the protective shell 4 on the outside of the connector plug 1, and by the elastic force of the reset spring 3, the protective shell 4 can be automatically reset. When the connector plug 1 needs to be used, the end cover 15 is rotated to make the connector plug 1 leak out, and then the connector plug 1 is inserted into the socket. At this time, the reset spring 3 is in a compressed state, and the protective shell 4 moves to the rear end. When the connector plug is used and pulled out, the protective shell 4 is automatically reset under the elastic force of the reset spring 3 to protect the connector plug 1, and then the end cover 15 is rotated to cover the end of the protective shell 4 to achieve dustproof;
[0023] A driving gear 10 is provided at one end of the rotating shaft 14 away from the end cover, and a dustproof retaining ring 11 is rotatably provided on one side of the fixed retaining ring 7. An opening groove 8 is provided on the outer ring of the fixed retaining ring 7 and the dustproof retaining ring 11. A gear ring 12 is provided on one side of the dustproof retaining ring 11, and the gear ring 12 is meshed with the driving gear 10. There are five opening grooves 8, and the five opening grooves 8 are evenly arranged in the circumferential direction on the fixed retaining ring 7. The number of opening grooves 8 of the dustproof retaining ring 11 and the fixed retaining ring 7 is the same. The dustproof retaining ring 11 is consistent with the opening grooves 8 on the fixed retaining ring 7. When the dustproof retaining ring 11 rotates, the fixed retaining ring 7 remains stationary. When the end cover 15 is closed, the opening grooves 8 on the fixed retaining ring 7 and the opening grooves 8 on the dustproof retaining ring 11 are staggered, and the dustproof retaining ring 11 blocks the opening grooves 8 of the fixed retaining ring 7, thereby preventing the entry of external dust. When the connector plug 1 is inserted for use, the end cover 15 rotates so that the opening groove 8 on the dustproof retaining ring 11 corresponds to the opening groove 8 on the fixed retaining ring 7, so that the outside air can enter the side of the dustproof retaining ring 11 from the air inlet and outlet holes 6 to dissipate heat at the end of the connector plug 1.
[0024] The rotating shaft 14 is a damping rotating shaft, and the outer wall of the protective shell 4 is provided with a protective cover 9 outside the driving gear 10. The protective shell 4 has an air inlet and outlet hole 6, and the outer wall of the protective shell 4 is provided with an air guide cover 5 outside the air inlet and outlet hole 6, which is a rectangular shell with one end open.
[0025] The diameter of the end cover 15 is larger than the outer diameter of the protective housing 4, and the end cover 15 is fixedly connected to the rotating shaft 14. When the end cover 15 rotates, the rotating shaft 14 is driven to rotate together, thereby driving the driving gear 10 to rotate.
[0026] The size of the opening groove 8 is smaller than the spacing between the opening grooves 8. The air inlet and outlet holes 6 are located in the area between the fixed retaining ring 7 and the flange ring 2. There are six air inlet and outlet holes 6, which are evenly arranged circumferentially on the protective shell 4. The end cover 15 rotates so that the opening groove 8 on the dustproof retaining ring 11 corresponds to the opening groove 8 on the fixed retaining ring 7, so that the outside air can enter the side of the dustproof retaining ring 11 from the air inlet and outlet holes 6 to dissipate heat at the end of the connector plug 1.
[0027] When the electrical connector is in use, a protective shell 4 is arranged on the outside of the connector plug 1, and the protective shell 4 can be automatically reset by the elastic force of the reset spring 3. When the connector plug 1 needs to be used, the connector plug 1 is leaked out by rotating the end cover 15, and then the connector plug 1 is inserted into the socket. At this time, the reset spring 3 is in a compressed state, and the protective shell 4 moves to the rear end. When the connector plug is pulled out after use, the protective shell 4 is automatically reset under the elastic force of the reset spring 3 to protect the connector plug 1, and then the end cover 15 is rotated to cover the end of the protective shell 4 to achieve dust prevention;
[0028] When the connector plug 1 is used and placed, the end cover 15 needs to be rotated and closed. When the end cover 15 rotates, the rotating shaft 14 is driven to rotate together, thereby driving the driving gear 10 to rotate. Through the meshing of the driving gear 10 and the ring gear 12, the dustproof retaining ring 11 is driven to rotate. Since the dustproof retaining ring 11 is consistent with the opening groove 8 on the fixed retaining ring 7, when the dustproof retaining ring 11 rotates, the fixed retaining ring 7 remains stationary. When the end cover 15 is closed, the opening groove 8 on the fixed retaining ring 7 and the opening groove 8 on the dustproof retaining ring 11 are staggered, and the opening groove 8 of the fixed retaining ring 7 is blocked by the dustproof retaining ring 11, thereby preventing the entry of external dust. When the connector plug 1 is inserted and used, the end cover 15 is rotated, so that the opening groove 8 on the dustproof retaining ring 11 corresponds to the opening groove 8 on the fixed retaining ring 7, so that the outside air can enter the side of the dustproof retaining ring 11 from the air inlet and outlet holes 6, so as to dissipate the heat of the end of the connector plug 1.
