The invention discloses a connection assembly of a crimping type low-temperature superconducting magnet pull rod and a manufacturing and mounting method thereof. The connection assembly comprises a carbon fiber pull rod main body (1), stainless steel metal sleeves (2) crimped on both ends of the carbon fiber pull rod main body (1), washers (3) installed on the stainless steel metal sleeves (2) andpre-tightening nuts (4) threaded on the stainless steel metal sleeves (2), wherein the diameter of a cylindrical hole of each stainless steel metal sleeve (2) is greater than that of the carbon fiberpull rod main body (1); the contact portions of the carbon fiber pull rod main body (1) and the stainless steel metal sleeves (2) are rough surfaces; and one sides, in contact with the carbon fiber pull rod main body (1), of the outlet end and the inlet end of each stainless steel metal sleeve (2) are provided with fillets chamfered at R1. According to the connection assembly of the crimping typelow-temperature superconducting magnet pull rod and the manufacturing and mounting method thereof, the structural design is reasonable, the energy loss is reduced, the strength is high without the sliding of the pull rod main body, the manufacturing cost is reduced, the manufacturing is convenient and fast, and the practicability is high.
