However, if the copper connector is pre-installed on the winding frame, the winding frame will be affected by the copper connector during the winding process, and the problem of unfavorable winding occurs due to the front opening . On the other hand, if the copper connector is assembled with the aluminum conductor and then installed on the bobbin, the aluminum conductor needs to reserve a longer line segment to facilitate the user to connect the aluminum conductor to the Copper connectors, in this way, the reserved long line will cause the winding to be loose and affect the electrical characteristics. In addition, the above-mentioned embodiments cannot be used on a wire reel that is relatively small or has too many pins, and there are limitations in use.

Therefore, the current wire frame structure is generally affected by the conductive pins during the implementation of the winding operation, and the winding cannot be carried out smoothly.
