Description

Transformer structure

This creation is about a transformer structure.

A transformer is a device that raises or lowers the voltage by applying Faraday's law of electromagnetic induction. Transformers typically contain two or more coils. The main purpose is to raise and lower the voltage of the alternating current, change the impedance and separate the circuit. The ratio of current or voltage between the two transformers depends on the number of turns of the two circuit coils. The one with more turns has higher voltage but lower current, and vice versa. If the leakage and other factors are removed, the voltage ratio of the two sides of the transformer is equal to the ratio of the number of coil turns of the two sides, that is, the voltage is proportional to the number of turns.

In order to further improve the various characteristics of the transformer, the related fields are not exhaustively developed. How to provide a transformer with better characteristics is one of the current important research and development topics, and it has become an urgent target for improvement in related fields.

The electrically conductive winding comprises a plurality of windings spaced apart from each other and the plurality of windings are electrical or structurally continuous uninterrupted electrical conductors. The insulating sheet is disposed on the inner surface of the magnetic core group having the center pillar. The plurality of conductive copper sheets and the plurality of windings are alternately stacked to form a winding structure, and the winding structure is coupled to the insulating sheet.

In one or more embodiments of the present invention, the surface of the wound structure is bonded using an adhesive material to fix the conductive winding of the wound structure and the plurality of conductive copper sheets to each other.

In one or more embodiments of the present invention, the conductive winding of the wound structure is bonded to the plurality of conductive copper sheets using an adhesive material.

In one or more embodiments of the present invention, the outer surface of the winding structure is adhered to an insulating tape.

Next, the secondary winding 121 and the conductive copper sheet 110 are bonded using the bonding material 310, thereby fixing the secondary winding 121 and the conductive copper sheet 110 to each other to form the winding structure 200. Then, the conductive material support structure is removed. Thus, the winding structure 200 can have a stable fixed structure without requiring a conductive material supporting structure. Therefore, the transformer structure 100 does not require a conductive material support structure.

Since the transformer structure 100 does not require a conductive material support structure, the overall size of the transformer structure 100 can be reduced, while the transformer structure 100 can have a large converted output energy in a fixed space.

As shown in FIG. 2, in particular, the insulating sheet 141 directly contacts the inner surface 130i of the core group 130 and the winding structure 200. More specifically, the insulating sheet 141 directly contacts the conductive copper sheet 110.

Further, since the transformer structure 100 has no conductive material supporting structure, the conductive copper sheet 110 will be adjacent to the magnetic core group 130, in order to avoid a short circuit problem between the conductive copper sheet 110 and the magnetic core group 130, in the body The surface of the part 111 is coated with an insulating material, which will effectively avoid the cause. The problem that the main body portion 111 is in direct contact with the magnetic core group 130 causes a short circuit.

As shown in FIG. 1 , since the transformer structure 100 is fixed by the extension portion 112 and electrically connected to other circuit components (such as a circuit board), solder is pre-plated on the surface of the extension portion 112 to assemble the transformer structure 100. Solder can be used to secure and electrically connect the extension 112 to other circuit components in other circuit components.

When the transformer structure 100 is assembled, the conductive winding 120 may be fixedly wrapped around the conductive material supporting structure, and the conductive copper sheet 110 is passed through the conductive material supporting structure during the process of fixing the conductive winding 120 around the conductive material supporting structure. Thus, the conductive copper sheet 110 and the secondary winding 121 are alternately stacked, while the conductive winding 120 is fixed in shape. Next, the secondary winding 121 and the conductive copper sheet 110 are bonded using the bonding material 310, thereby fixing the secondary winding 121 and the conductive copper sheet 110 to each other to form the winding structure 200. Then, the conductive material support structure is removed. Thus, the winding structure 200 can have a stable fixed structure without requiring a conductive material supporting structure.
