Function of transformer skeleton and introduction of names of various parts; Transformer skeleton, or transformer wire frame, is called Bobbin in English, which is the main structural component of transformer. "skeleton" vividly describes its role in transformer. Transformers are widely used in today's society, and the corresponding main body is also essential, so the skeleton plays an irreplaceable role at present. Function of skeleton in transformer and name of each part:
1. Provide winding space for copper wire in transformer, and the part where the skeleton provides this function is called winding slot.
2. Fix the magnetic core in the transformer. The part of the skeleton where the magnetic core is inserted is called the magnetic core hole. There are round holes, square holes and special-shaped holes, which are determined by the matching magnetic core.
3. The wire-passing slot in the skeleton provides a path for the transformer to pass through when it is wound in production.
4. The metal pins in the skeleton are the pillars wound by copper wires of the transformer; After soldering, it is connected to the PCB board, which plays a conductive role when the transformer works.
5. The retaining wall at the bottom of the skeleton can fix the PCB board; Provide a certain distance space for the tin stack and PCB board, and the magnetic core and PCB board generated during soldering; Isolate the magnetic core from the tin stack to avoid bad withstand voltage.
6. The convex points, concave points or chamfers in the skeleton can determine the placement direction or pin sequence of the transformer when in use.
