[0035] Reference Figure 4-Figure 6, a partition 16 is fixedly connected to the inner surface of the mobile shell 4, and a vent hole 17 is opened on the surface of the partition 16. A sealing ring 18 is threadedly connected to the inner wall of the mobile shell 4. The sealing ring 18 is detached from the mobile shell 4 by reversing, which is convenient for putting desiccant particles into the mobile shell 4 to prevent the interface 2 from getting wet. A sealing plug 19 is arranged at the bottom of the mobile shell 4, and a discharge port is opened at the bottom of the mobile shell 4.

[0036] Working principle: the fixed shell 3 and the mobile shell 4 shield the interface 2 to prevent dust from entering the interface 2 when it is not in use. Desiccant particles are placed inside the mobile shell 4 to absorb moisture around the interface 2 through the air vent 17 to prevent the interface 2 from getting wet. When the cable needs to be inserted into the interface 2, the mobile shell 4 is manually pushed toward one side of the fixed shell 3, the airbag 5 is forced to compress the reset spring 7, and the sealing block 10 is inserted into the inside of the air jet 9, so that the air in the airbag 5 can only enter the mobile shell 4 through the telescopic tube 8 until it passes through The air jet 9 contacts the port of the cable. Since the air jet 9 is tilted downward, the gas flows downward, reducing the dust attached to the port from entering the interface 2. When the movable shell 4 drives the fixed block 15 to be inserted into the groove 11, the squeezing force of the fixed block 15 causes the elastic member 12 to contract. When the movable shell 4 cannot move, the elastic force of the elastic member 12 causes the positioning block 13 to move toward the side of the fixed block 15 until the fixed block 15 is inserted into the inside of the jack 14, thereby positioning the movable shell 4 and improving the protection effect of the interface 2 on the chassis body 1.
