Abstract
The invention discloses a wire clamping unit for a power device. The wire clamping unit comprises a screw, a connection board and a rack. The rack is formed by integration of a first press plate, a second press plate and a bending steel plate. The bottom of the screw at the top of the rack is connected with an upper surface of the connection plate with one end through the interior of the rack, via threaded holes provided in the central parts of the first and second press plates. One end of the second press plate is provided with two clamp blocks. One side of the inner wall of the rack is provided with slots corresponding to the two clamp blocks. The wire clamping unit for a power device prevents loose of threads at the top and is able to effectively press wires in the rack tightly, thereby guaranteeing the stability of the pre-tightening force of the wires in the rack and keeping the wires from heating. In addition, the wires are prevented from loosing or stripping off and high safety and reliability of wire joints are achieved, thereby guaranteeing normal operation of circuit breakers and protecting users from great hidden troubles or insecurity.
