The invention discloses a composite high-temperature superconductor connector compatible with forced flow cooling and electric connection. A compatible current transverse transmission and longitudinal cooling loop can be realized among multiple layers of parallel solenoid coils. An inner side step of the copper terminal is connected with an end part metal core pipe of the composite high-temperature superconducting conductor to realize internal positioning of the high-current-carrying superconducting joint, an outer side step-shaped structure and a low-temperature system forced flow cooling pipeline are assembled together, and a low-temperature tin material is welded to form a melting pool to form a complete closed loop; during welding, the front part of the metal plug is inserted into the through hole of the copper terminal and is connected with the metal core tube at the end part of the conductor, thereby ensuring that soldering tin does not immerse the forced flow cooling loop. The low-temperature forced fl
