Abstract

A power adapter including a first substrate, a second substrate, a transformer and an insulating frame is provided. The first substrate includes a first terminal set. The second substrate includes a second terminal set. The transformer includes a primary side connection terminal and a secondary side connection terminal, wherein the primary side connection terminal is connected to the first terminal set and the secondary side connection terminal is connected to the second terminal set. The insulating frame is disposed between the first substrate and the second substrate, and the transformer leans against the insulating frame.

Claims

1. A power adapter, comprising:

a first substrate, comprising a first terminal set;

a second substrate, comprising a second terminal set;

a transformer, comprising a primary side connection terminal and a secondary side connection terminal, wherein the primary side connection terminal is connected to the first terminal set and the secondary side connection terminal is connected to the second terminal set; and

an insulating frame, disposed between the first substrate and the second substrate, wherein the transformer comprises a first side surface and a second side surface opposite to the first side surface, the primary side and the secondary side are located on the first side surface, and the first substrate, the second substrate and the insulating frame lean against the first side surface of the transformer.

2. The power adapter as claimed in claim 1, further comprising at least one primary side component and at least one secondary side component, wherein the primary side component is disposed on the first substrate and coupled to the primary side connection terminal, the secondary side component is disposed on the second substrate and coupled to the secondary side connection terminal, and the insulating frame is configured to isolate the primary side component and the secondary side component from one another.

3. The power adapter as claimed in claim 1, wherein the first substrate and the second substrate are substantially parallel to each other, and the first substrate and the second substrate are located on two opposite sides of the transformer.

5. The power adapter as claimed in claim 1, wherein a creepage distance from the primary side connection terminal to the secondary side connection terminal is substantially greater than or equal to 6.5 mm.

6. The power adapter as claimed in claim 1, wherein a thickness of the insulating frame is substantially greater than or equal to 0.7 mm.

7. The power adapter as claimed in claim 1, further comprising a plurality of functional pins, and each of the functional pins connecting the first substrate and the second substrate.

8. The power adapter as claimed in claim 1, further comprising a plurality of fixed pins and a frame ground circuit, and the frame ground circuit being disposed on the second substrate.

9. The power adapter as claimed in claim 1, further comprising a connecting port disposed on the second substrate or the first substrate and electrically connected to an external electronic component.

10. The power adapter as claimed in claim 1, further comprising a shielding case covering at least a part of the transformer, the first substrate, and the second substrate.
