| 摘要 | An improved structure of a transformer includes a bobbin covering at least a portion of a magnetic core set which has a magnetic loop passing through the bobbin, wherein winding grooves and at least one connecting portion extending sideways are provided on the outer peripheral side of the bobbin, and a plurality of notches with lateral openings are provided on the connecting portion. Coils are wound in the winding grooves of the bobbin. The coils have at least a plurality of line ends, each line end passing through a different notch. One positioning pin is embedded in each of the winding grooves near the lateral opening. The positioning pins hold the respective line ends in place by pressing against them. A casing is fitted on the outer peripheral side of the coils to create separation between the coils and the magnetic core set. The casing is provided with a hollow opening such that the outer peripheral side of the coils facing the airflow is exposed to improve the overall heat dissipating efficiency. | ||

| 主权项 | 1. An improved structure of a transformer, comprising: a magnetic core set composed of a plurality of magnetic cores; a bobbin covering at least a portion of the magnetic core set which has a magnetic loop passing through the bobbin, wherein winding grooves and at least one connecting portion extending sideways are provided on the outer peripheral side of the bobbin, and a plurality of notches with lateral openings are provided on the connecting portion, each notch being provided with a positioning pin near the later opening; coils wound in the winding grooves of the bobbin, wherein the coils have at least a plurality of line ends, each line end passing through a different notch and positioned by a positioning pin which pressed on a side thereof; and a casing fitted on the outer peripheral side of the coils to form an insulating shield between the coils and the magnetic core set, wherein the casing is provided with a hollow opening such that the outer peripheral side of the coils facing the airflow is exposed. | ||
