Transformer

The invention discloses a transformer which comprises an iron core, a primary winding and a secondary winding. The secondary winding comprises a first center tap seat, a second center tap seat and a secondary conductive column arranged at opposite ends of the first center tap seat and the second center tap seat, the iron core sleeves outside the secondary conductive column, a first through hole is formed in the middle of the first center tap seat, a second through hole is formed in the middle of the second center tap seat, and one end of the secondary conductive column penetrates the first through hole to be fixedly connected with the first center tap seat while the other end of the same penetrates the second through hole to be fixedly connected with the second center tap seat. The transformer is simple to process, simple and convenient to maintain, high in transformation rate and low in loss, and product processing difficulty, processing cost and using cost are lowered. 本发明公开了种变压器，包括铁芯、初级绕组及次级绕组，所述初级绕组绕制于所述铁
