Structure for fixing lead wire by adopting upper support plate of clamping piece

The utility model relates to a structure for fixing a lead by adopting a clamping piece upper support plate, which belongs to the technical field of transformer low-voltage lead structures and comprises a connecting groove rod, a plurality of conducting bar clamping pieces are welded on the connecting groove rod, and each conducting bar clamping piece comprises a lead fixing mounting frame. The lead fixing and mounting rack is provided with a press-fit board which is connected and fixed with the lead fixing and mounting rack through a bolt, a board lead clamp is arranged between the press-fit board and the lead fixing and mounting rack, and a clamping groove integrated with the board lead clamp is arranged between the board lead clamp and the press-fit board. The device has the characteristics of good structural stability and long service life. The problem that a resin bent plate of the transformer is broken or a bolt falls off due to vibration of the conducting bar is solved. Transformer short circuit caused
