[0033] The dustproof mechanism is respectively arranged in the first connector 1 and the second connector 2, and is used to prevent dust from entering the first connector 1 and the second connector 2. The dustproof mechanism can prevent dust from entering the first connector 1 and the second connector 2, and can also protect the second conductive column 21 and the first conductive column 15, reduce corrosion from external factors, and increase service life.

[0034] In the utility model, the dustproof mechanism includes five sockets 8 opened at one end of the first connector 1, a first blocking plate 12 corresponding to the first conductive column 15 is arranged in the socket 8, a connecting plate 20 is fixedly connected between two adjacent first blocking plates 12, a groove corresponding to the connecting plate 20 is arranged inside the first connector 1, and first springs 9 are arranged inside the sockets 8 on both sides, and the two ends of the first spring 9 are respectively fixedly connected to the socket 8 and the side close to each other of the first blocking plate 12. Through the setting of the first blocking plate 12, the socket 8 can be blocked, the socket 8 can be dustproof, and the second conductive column 21 can be protected. The first blocking plates 12 on both sides are made of insulating material, and the remaining first blocking plates 12 are made of conductive material.

[0035] In the utility model, the inner wall of one side of the second connector 2 is fixedly connected to two connecting posts 18 corresponding to the first side blocking plate 12, the outer wall sliding sleeves of the connecting posts 18 and the first conductive posts 15 are provided with the same second blocking plate 14, the outer wall sleeves of the connecting posts 18 are provided with a second spring 13, and the two ends of the second spring 13 are respectively fixedly connected to the second blocking plate 14 and the side of the second connector 2 close to each other.

When the second plugging plate 14 contacts the first connector 1, the second plugging plate 14 will be driven to slide through the first connector 1, and the first plugging plate 12 will be driven to slide through the first conductive column 15, until the two ends of the first plugging plate 12 contact the first conductive column 15 and the second conductive column 21 respectively, and the card block 11 is stuck in the corresponding card slot 6, at which time the two corresponding connecting wires 3 are connected;

[0042] When the first connector 1 and the second connector 2 are separated, the first blocking plate 12 pops out under the force of the socket 8 to protect the conductive plate 10 from dust. At the same time, the second blocking plate 14 is pushed out under the force of the second spring 13 to protect the inside of the second connector 2 from dust.
