The role of the skeleton in the transformer of the following main points:
1, to provide space for the transformer winding copper wire
2, fixed transformer core.
3, provided the backbone trunking path line transformer winding to produce.
4, the metal skeleton of the pin copper wire wound transformers pillars; after solder connected with the PCB board, play a role in conducting the work of the transformer.
5, skeleton bumps, pits or chamfer, may decide to place the pin direction or order of transformers.
