The invention provides an LNG (liquefied natural gas) filling pipe connector, and belongs to the technical field of ship machinery. By the aid of the LNG filling pipe connector, problems of frost condensed on the outer walls of pipelines during LNG filling at present and influence on the service lives of equipment and filling operation can be solved. The LNG filling pipe connector comprises an inner pipe and an outer pipe. The inner pipe and the outer pipe are integrally formed, an annular cavity is formed in a gap between the inner pipe and the outer pipe, liquid nitrogen connecting pipes which are communicated with the cavity are connected onto the outer pipe, a plurality of first superconducting coils are axially arranged on the outer pipe and are connected with current controllers by wires, a circular ring further sleeves the outer pipe, magnets are arranged on the circular ring, an inner ring of the circular ring is peripherally provided with a plurality of brushes, and the brushes can be in contact with the outer pipe wall of the outer pipe. The LNG filling pipe connector has the advantages that the LNG filling pipe connector comprises the first superconducting coils and the circular ring, the first superconducting coils on each row can be sequentially powered on and off under the control of the corresponding current controllers, accordingly, the circular ring can be attracted to move back and forth along the outer pipe, frost on pipelines can be scraped by the brushes, condensation can be prevented, and filling operation can be facilitated.
