Abstract

A transformer assembly structure includes a transformer and a carrying seat. The transformer includes a bobbin, a winding coil assembly and a magnetic core assembly. The winding coil assembly includes a primary winding coil and a secondary winding coil. The carrying seat includes a main body and a first lateral wing. The main body has an edge. The first lateral wing includes a first positioning structure. The edge of the main body of the carrying seat is located at an inner side of an outer edge of the magnetic core assembly. The outlet part of the primary winding coil is managed and positioned by the first positioning structure.

First claim

What is claimed is:

1. A carrying seat disposed on a bottom of a transformer, the transformer comprising a bobbin, a winding coil assembly and a magnetic core assembly, the winding coil assembly comprising a primary winding coil and a secondary winding coil, the primary winding coil and the secondary winding coil being wound around the bobbin, the bobbin being arranged between a first magnetic core and a second magnetic core of the magnetic core assembly, the carrying seat comprising:
a first lateral wing comprising a first positioning structure; and
a main body connected with the first lateral wing,
wherein an edge of the main body of the carrying seat is located at an inner side of an outer edge of the magnetic core assembly, wherein an outlet part of the primary winding coil is connected with the first positioning structure, so that the outlet part of the primary winding coil is managed and positioned by the first positioning structure.

2. The carrying seat according to claim 1 , further comprising a second lateral wing connected with the main body, wherein the first lateral wing and the second lateral wing are opposed to each other with respect to the main body, the second lateral wing comprises a second positioning structure, an outlet part of the secondary winding coil is connected with the second positioning structure, the first positioning structure and the second positioning structure are separated from each other by a specified distance so that the outlet part of the secondary winding coil is managed and positioned by the second positioning structure.

3. The carrying seat according to claim 2 , wherein the second lateral wing of the carrying seat further comprises a third positioning structure.

4. The carrying seat according to claim 3 , wherein each of the first positioning structure, the second positioning structure and the third positioning structure includes at least one perforation.

5. The carrying seat according to claim 3 , wherein the third positioning structure is a notch, and the outlet part of the secondary winding coil is locked in the notch, so that the outlet part of the secondary winding coil is positioned by the notch.

6. The carrying seat according to claim 2 , wherein the carrying seat further comprises a third lateral wing and a fourth lateral wing, wherein the third lateral wing and the fourth lateral wing are opposed to each other with respect to the main body, and the third lateral wing and the fourth lateral wing are arranged between the first lateral wing and the second lateral wing.

7. The carrying seat according to claim 6 , wherein the carrying seat comprises two auxiliary positioning parts, which are disposed on the third lateral wing and the fourth lateral wing of the carrying seat, respectively, wherein the two auxiliary positioning parts are protruded from a first surface of the carrying seat for assisting in positioning the magnetic core assembly.

8. The carrying seat according to claim 7 , wherein the main body, the first lateral wing, the second lateral wing, the third lateral wing, the fourth lateral wing and the two auxiliary positioning parts are integrally formed with each other.

9. The carrying seat according to claim 1 , wherein the carrying seat further comprises at least one supporting part, wherein the at least one supporting part is disposed on a second surface of the carrying seat, and an altitude of the carrying seat is increased by the at least one supporting part, so that an accommodation space is formed under the carrying seat.

10. The carrying seat according to claim 9 , wherein the at least one supporting part is integrally formed with the carrying seat.
