Abstract

A transformer with a connector is described, having a primary side and a secondary side and composed of a winding base, a core and windings, wherein the core is inserted into the winding base and the windings are wound on the winding base, and the transformer is characterized in that a connector is disposed at the secondary side of the transformer and connected to an external connector disposed at a load to which a signal fed through the primary side to the transformer is outputted when the connector and the external connector are connected to each other. In the transformer, the connector conventionally disposed on the circuit board is disposed on the transformer, saving the space that would otherwise be needed for connection wires between the transformer and the connector. Therefore, the circuit board has a reduced area, effectively saving the manufacturing cost for a product to which the circuit board is applied.

Claims

1. A transformer with a connector, the transformer having a primary side and a secondary side and composed of a winding base, a core and windings, wherein the core is inserted into the winding base and the windings are wound on the winding base, and characterized in that:

the connector is disposed at the secondary side of the transformer and connected to an external connector disposed at a load to which a signal fed through the primary side to the transformer is outputted when the connector and the external connector are connected to each other.

2. The transformer according to claim 1, wherein the transformer is an EE type core transformer.

3. The transformer according to claim 2, wherein the connector takes a form of a protrusion.

4. The transformer according to claim 2, wherein the connector takes a form of an indentation.

5. The transformer according to claim 3, wherein the connector is disposed at a side surface of the winding base located at the secondary side of the transformer.

6. The transformer according to claim 4, wherein the connector is disposed at a side surface of the winding base located at the secondary side of the transformer.

7. The transformer according to claim 3, wherein the connector is disposed at an upper side surface of the winding base located at the secondary side of the transformer.

8. The transformer according to claim 4, wherein the connector is disposed at an upper side surface of the winding base located at the secondary side of the transformer.

9. The transformer according to claim 1, wherein the transformer is a CI type core transformer.

10. The transformer according to claim 8, wherein the connector takes a form of a protrusion.

11. The transformer according to claim 10, wherein the connector is disposed at a side of the winding base located at the secondary side of the transformer.

12. The transformer according to claim 1, wherein the transformer is an EI type core transformer.

13. The transformer according to claim 12, wherein the connector takes a form of a protrusion.

14. The transformer according to claim 13, wherein the connector is disposed at two sides of the winding base located at the secondary side of the transformer.

15. The transformer according to claim 13, wherein the connector is disposed at two ends of a side of the winding base located at the secondary side of the transformer.

16. A transformer with a connector, the transformer having a primary side and a secondary side and composed of a winding base, a core and windings, wherein the core is inserted into the winding base and the windings are wound on the winding base, and characterized in that:

the connector is disposed at the winding base located at the secondary side of the transformer and vertically or horizontally connected to a load so that a signal from the transformer is outputted to the load.

17. The transformer according to claim 16, wherein the transformer is a CI type core transformer.

18. The transformer according to claim 17, wherein the connector takes a form of an indentation.

19. The transformer according to claim 18, wherein the connector is disposed at a side of the winding base located at the secondary side of the transformer.

20. The transformer according to claim 16, wherein the transformer is an EI type core transformer.

21. The transformer according to claim 20 wherein the connector takes a form of an indentation.

22. The transformer according to claim 21, wherein the connector is disposed at two sides of the winding base located at the secondary side of the transformer.

23. The transformer according to claim 22, wherein the connector is disposed at two ends of a side of the winding base located at the secondary side of the transformer.

24. The transformer according to claim 16, wherein the load is a lamp.

25. The transformer according to claim 16, wherein a resilient piece or a conductive rubber is disposed in the connector.
