Magnetic attraction data line with dustproof structure

The utility model discloses a magnetic attraction data line with a dustproof structure. The magnetic attraction data line comprises a wire rod, a plugging connector and a magnetic attraction connector. A magnetic suction connector comprises a magnetic suction seat, a magnetic suction head and a dustproof cover, a dustproof cavity is formed in the magnetic suction seat, and the magnetic suction head is arranged on the magnetic suction seat, located in the dustproof cavity, matched with the dustproof cover and arranged on the magnetic suction seat in a back-and-forth rotating mode and covers an opening in the upper end of the dustproof cavity, so that the dustproof cover can be rotated under the condition that the magnetic suction connector is not used; the dustproof cover covers the opening in the upper end of the dustproof cavity, so that external dust is prevented from falling on the magnetic suction head, when the data line is used next time, only the dustproof cover needs to be rotated, the magnetic suctio
