Fig. 2 is a side view of a power take-out tab provided in an embodiment of the present disclosure. As shown in fig. 2, the electric segment 20 of the electric plug includes a plate portion 21 and a bending portion 22. The plate-like portion 21 is parallel or coplanar with the wire connection section 10. One side of the plate-shaped portion 21 is connected to the terminal block 10, and the bent portion 22 is connected to the other side of the plate-shaped portion 21 away from the terminal block 10. The bent portion 22 protrudes toward one side of the plane where the plate-like portion 21 is located.

The plate-shaped part 21 is parallel to or coplanar with the wiring section 10, so that the plate-shaped part 21 and the wiring section 10 can be conveniently stamped out through one plate, and the power taking insertion piece is easier to process. The bent portion 22 protrudes to one side of the plane where the plate-shaped portion 21 is located, so that the bent portion 22 has certain elasticity and is convenient to contact with a conductor plate in the bus duct.
