Description

[0002] The transformer in the prior art is composed of a frame wrapped with enameled wire turns and a plurality of magnetic cores. The semi-finished transformer assembled by the turns, the frame and the magnetic cores not only needs to be encapsulated by glue filling, but also needs to be fixed by fixing parts before the finished transformer can be formed.

[0003] Before the semi-finished transformer is encapsulated by glue, the electrical performance of the semi-finished transformer must be tested first, so as to reduce the waste of labor and materials caused by defective products entering the glue encapsulation, and reduce the waste of materials and labor losses caused by rework and disassembly of defective products after glue encapsulation.
