Technical Field

[0001] This utility model relates to the field of transformers, and more particularly to small transformers for electronic products. Background Technology

[0002] A transformer, a small transformer used in electronic products, consists of a frame, a core, and coils. The coils are wound around the core, which passes through the frame. The frame has bent terminals for connecting the coil leads. In actual production, to improve efficiency, automation is used, and the coils are automatically wound onto the frame. To avoid this automated winding process, the terminals are straight before winding and are bent afterward. The coil has several leads, each designed for a different voltage, making the transformer widely applicable. Utility Model Content

[0003] The technical problem solved by this utility model is: how to classify the coil leads to avoid mutual contact and achieve a neat and orderly effect.

[0005] According to the above technical solution, the lead-out end of the coil wound on the wire frame passes through the wire-passing notch, then through the wire-passing groove between the first-type and second-type protrusions, or the wire-passing groove between the second-type protrusion and the lower limit edge, and enters the wire-passing groove between adjacent first-type protrusions, finally winding onto the terminal. Due to the clearance and guidance provided by the wire-passing notch and wire-passing groove, multiple leads can be classified and guided, connecting to the corresponding terminals, avoiding contact between leads, and achieving a neat and orderly effect.

[0006] Type I and Type II protrusions, along with the lower limiting edge, are all located on the bottom surface of the wire frame. The lower limiting edge is V-shaped, and a pair of opposing lower limiting edges limit the T-shaped iron core. Each wire guide groove is located on the bottom surface of the wire frame, and the coil leads are distributed on the bottom surface of the wire frame. The terminals are bent upwards, so that the leads wound from bottom to top around the terminals can be taut on the terminals. The lower limiting edge has a dual function: it can guide and limit the coil leads, and it can also limit the T-shaped iron core.

[0007] The top of the wire frame is provided with an upper limit edge, which is V-shaped. A pair of opposing upper limit edges limit the T-shaped iron core.

[0008] The edge of the wire frame is provided with a core limiting notch, which is located between a pair of lower limiting edges. The T-shaped core fits between the pair of lower limiting edges and engages in the core limiting notch.

[0009] The core consists of a pair of T-shaped iron cores joined together facing each other, with tape wrapped around the periphery of the cores.

[0010] The technical effects of this utility model include:

[0011] First, the structure of the coil frame is suitable for automated coil winding, and after the coil is wound, the terminals are bent.

[0012] Secondly, the setting of Class I and Class II convex points and the lower limit edge can limit and guide the lead-out end of the coil, which is conducive to the neat and orderly structure of the transformer. Attached Figure Description
