Transformer and assembling method thereof

Abstract

A transformer includes a winding frame, a primary coil, an insulating cover, a secondary coil, and a core assembly. The winding frame has a winding portion formed with a first side portion and a second side portion oppositely. A plurality of first pins and second pins are disposed on the first and second side portions, respectively. The primary coil is wrapped around the winding portion of the winding frame and connected to the first pins. The insulating cover is fitted over the primary coil. The secondary coil is wrapped around the insulating cover and connected to the second pins. The core assembly is arranged on the winding frame. A transformer assembling method is also disclosed. The coil wrapping process for the transformer can be expedited and associated cost can be reduced.
