The BOBBIN refers to a skeleton, also known as a transformer skeleton, or a transformer BOBBIN, and is generally called BOBBIN in English, and is a main structural component of a transformer. Transformers are widely used in the modern society, and corresponding main bodies are indispensable, so that the framework has a function of no substitution. The skeleton plays a main role in the transformer in the following points: 1. providing winding space for copper wires in the transformer, and 2, fixing a magnetic core in the transformer. 3. The wire grooves in the framework provide wire passing paths for the winding of the transformer. 4. The metal pin in the framework is a pillar wound by copper wires of the transformer; after soldering tin, the transformer is connected with the PCB and plays a role in conducting electricity when the transformer works. 5. The convex points, concave points or chamfers in the framework can determine the placement direction or stitch sequence of the transformer when in use. The framework is generally classified according to the types of magnetic cores (or iron cores) used by the transformer, such as EI, EE, EF, EPC, ER, RM, PQ, UU and the like, and each type can be distinguished according to the size of the magnetic core (or iron core), such as EE5, EE8, EE13, EE19 and other types with different sizes.
