Data transmission connection structure

The utility model relates to a data transmission connection structure, which comprises a plug, a socket, jacks, lantern rings and contact pins, a pushing structure is coaxially arranged on the outer side of each lantern ring, each pushing structure comprises a contact ring protruding out of the end face of the plug and a pushing piece fixedly connected to the back side of the contact ring, and the end part of each pushing piece is attached to the outer wall of the corresponding lantern ring; when the plug is in butt joint with the socket, the contact ring is completely pushed into the plug. According to the scheme, the movable grooves are coaxially formed in the outer sides of the jacks, the pushing structures are embedded in the inner sides of the movable grooves in a sliding mode, and the pushing pieces of the pushing structures are used for pushing the lantern rings to be close to the axis positions of the lantern rings when the plug and the socket are connected in an inserted mode, so that the lantern rin
