Abstract
The invention discloses a novel special clip for a transformer. The clip comprises a transformer connecting end and a conductor connecting end, wherein a conductor mounting hole and first threaded holes communicated with the conductor mounting hole and used for mounting pressing bolts are formed on the conductor connecting end; and the conductor mounting hole is a threaded hole. When the pressing bolts apply force and compress conductors, the threaded pointed parts can puncture oxide layers on the surfaces of the conductors to be embedded into the conductors so as to eliminate the influence on the contact between the clip and the conductors from the oxide layers, then the clip and the conductors can be in close contact and the contact resistance is reduced; disc-shaped pressing plates are arranged on the pressing bolts, so that the conductors and the clip can be connected in a constant-pressure state, and loose contact caused by thermal expansion and contraction of the conductors is effectively eliminated; and jaw structure on the transformer connecting end can ensure favorable close contact between the surface of a second threaded hole and the surface of the transformer terminal, and the contact resistance is reduced; and the conductor connecting end can be connected with power conductors of which the sectional areas range from 35mm<2> to 240mm<2>, so that the clip has strong universality.
