What Is The Role Of The Bobbins in The Transformer?

The shape of the transformer bobbins can be said to be changeable.

There are at least a dozen kinds of transformer bobbins of the same type. Some are different in the height of the retaining wall, and some are different in the size of the winding slot, especially the pin pitch and row pitch. If they are different, it will also cause difficulties for customers to choose.

As Shaanxi Gold -stone , we always encounter this situation when providing size is slightly different, the existing mold cannot be used. If it is simple, it must cooperate with a part of the newly opened mold, and if it is complex, the whole set of molds must be reopened. The manufacturing cost of the transformer is greatly increased,

In the industry, the transformer factory is unable to accept orders because it cannot find suitable molds. Many friends of the transformer factory have a consensus that among all the constituent materials of the transformer, the skeleton is hard to find. For the skeleton factory, many sets of molds have been developed by itself. Because there are no orders placed on the shelf, it is unknown that some transformer factories have given up their orders because they can not find the molds for such products.

What is the role of the bobbins  in the transformer?

1. Provide winding space for the copper wire in the transformer

3. The wire passing slot in the skeleton provides a wire passing path for the production and winding of the transformer.

4. The metal pin in the skeleton is the pillar wound by the copper wire of the transformer; After soldering, it is connected with the PCB board and plays a conductive role in the operation of the transformer.

5. The retaining wall at the bottom of the skeleton can fix the PCB;

6. The convex point, concave point or chamfer in the skeleton can determine the placement direction or stitch sequence of the transformer when it is used.

As the transformer is widely used in today's society, its corresponding main transformer bobbins  is also indispensable, which is the reason why bobbins  cannot be replaced.
