Abstract
The invention discloses a device capable of folding a wire. The device capable of folding the wire comprises a copper strip, wherein the copper strip is folded into N folds and arranged in a mounting rack. N is a positive integer, each fold of the copper strip is of a U shape. N short circuit units are connected with two sides of each fold of the copper strip in short circuit mode. A driving unit is used to drive the N short circuit units to move up and down along both sides of each fold of the copper strip. The N short circuit units are used to adjust the connecting length of folded copper strip so as to achieve inductance from 0.2 microhenry to 0.8 microhenry.
