Problems solved by technology

However, since the primary coil and the secondary coil provided in the transformer should be isolated from each other in order to secure a space for the insulation distance required between the coils and satisfy safety standards, the process for manufacturing the transformer is complicated.
[0004] In addition, in the case of winding a coil, the number of turns of the coil and / or the winding position of the coil may not be uniform according to individual workers

Abstract

The invention provides a transformer and a plate coil molded body. The transformer includes a magnetic core, a primary coil module including a coil support arranged in the magnetic core and a primary coil formed on the coil support, an upper secondary coil module including an upper insulation molded body arranged on an upper portion of the primary coil module and an upper plate coil buried in the upper insulation molded body and arranged to face the primary coil, and a lower secondary coil module including a lower insulation molded body arranged on a lower portion of the primary coil module and a lower plate coil buried in the lower insulation molded body and arranged to face the primary coil.

Description

[0001] This application claims priority with Korean patent applications No. 10-2015-0109156 and 10-2015-0125713 filed at the Korean Intellectual Property Office on July 31, 2015 and September 4, 2015, respectively. The Korean patent application The public content of is included here by reference. Technical field [0002] The present invention relates to a transformer provided in a power supply device or the like. Background technique [0003] The power unit is provided in the power supply device. The size of the transformer provided in the power unit is approximately 1 / 3 of the total size of the power unit. Transformers have a small number of components (including cores, coil formers and coils). However, since the primary coil and the secondary coil provided in the transformer should be isolated from each other in order to ensure a space for the required insulation distance between the coils and meet safety standards, the process for manufacturing the transformer is complicated....
