[0023] As shown in the figure, it is a structure schematic view of a Micro USB connector with a dustproof mechanism of a preferred embodiment of the utility model; Figs. 1-3

[0024] ​In the embodiment, the joint body 1 is provided with a joint hole 3 at the front end, and connecting blocks one 4 are arranged on both sides of the joint hole 3. The dustproof mechanism 2 comprises a dustproof plug 5 which is inserted into the joint hole 3. The dustproof plug 5 is inserted into the joint hole 3, thereby effectively preventing dust from entering the joint hole 3 and reducing the connection instability and connection effect. One end of the dustproof plug 5 is provided with a cover plate 6, and an inner cavity 7 is arranged on the end face of the cover plate 6 away from the dustproof plug 5. The inner cavity 7 is a circular cavity, and through grooves 8 are arranged on both sides of the inner cavity 7. A winding reel 9 is rotatably arranged in the inner cavity 7, and the winding reel 9 is circular. Connecting blocks two 10 are arranged on both sides of the inner wall of the winding reel 9. Through holes 11 are arranged on both surfaces of the cover plate 6. Pulling ropes 12 are connected to the connecting blocks one 4. One end of the pulling rope 12 passes through the through hole 11 and the through groove 8 and is connected to the connecting block two 10. A torsional spring is arranged in the inner cavity 7, and both ends of the torsional spring are connected to the inner cavity 7 and the winding reel 9. In use, the dustproof plug 5 is pulled out of the joint hole 3, the cover plate 6 is pulled to pull the pulling rope 12 out of the inner cavity 7, and the winding reel 9 is rotated to drive the torsional spring to contract. After the dustproof plug 5 is inserted into the joint hole 3, the torsional spring releases the rotating force to drive the winding reel 9 to rotate, and the winding reel 9 winds the pulling rope 12 to avoid occupying a large space outside.

[0025] In the embodiment, the pulling rope 12 is made of steel wire rope, which has good toughness and strength.

[0026] In the embodiment, wear-resistant rings 13 are arranged in the through holes 11, and the wear-resistant rings 13 are made of stainless steel. The wear-resistant rings 13 can prevent the pulling rope from causing more wear to the through holes 11.

[0027] The Micro USB joint with the dustproof mechanism has a common mechanical installation mode, connection mode or setting mode, and can be implemented as long as the beneficial effects are achieved.
