Bi-2212 super conductive conductor connector

The invention discloses a Bi-2212 super conductive conductor connector. The Bi-2212 super conductive conductor connector comprises an oxygen-free copper connector box, the oxygen-free copper connector box comprises a box body with an opened top and two ends, the bottom of the right side of the box body is provided with a groove, and a Bi-2212 super conductive conductor is installed in the groove in a embedded mode; a NbTi super conductive cable is placed in the box body, and the top of the box body is provided with a fixing plate in a pressed mode and is then integrally soldered, wherein the NbTi super conductive cable located at the upper portion of the Bi-2212 super conductive conductor is a NbTi super conductive cable core which is back twisted and of which an armor layer is removed. According to the Bi-2212 super conductive conductor connector, the contact resistance of the super conductive cable and the connector is effectively lowered, therefore the resistance value of the connector is lowered, when the connector runs at low temperature, the connector resistance should be smaller than 20 nano ohm, and big-current and low-loss running at 10 kA or above and performance test conditions are met.
