Description

Stacked wire group transformer with adjustable leakage inductance

The present invention relates to a transformer, and more particularly to a transformer in which a laminated wire group can adjust leakage inductance.

According to the current electronic system or electronic device, in order to ensure the stability during the implementation of the power-on, a feedback circuit is generally added to the output end to transmit the working state of the output terminal to a control chip in a feedback signal to utilize the The feedback signal judges whether the overall circuit is normal or not, and performs moderate fine adjustment. Therefore, in addition to the first line cake and the second line cake used for transformer power, the current transformer also has an auxiliary coil that is only used to transmit electrical signals, just like the Republic of China new M491298 patent. case.

However, when the conventional transformer structure is wound around the auxiliary coil, the auxiliary coil is mostly wound on the same wire frame as the first wire cake and the second wire cake, since the auxiliary coil is wound on the first wire. Between the line cake and the second line cake, and the number of turns of the auxiliary coil is designed to be smaller than the first line cake or the second line cake, so that the auxiliary coil is formed after the winding of the transformer is completed. a sparsely wounded pattern creates a gap between the first line cake and the second line cake that affects the degree of magnetic coupling between the first line cake and the second line cake.

Therefore, the applicant of the present application has proposed a patent application for a combined transformer with a leakage inductance adjustment function, and a new patent of Chinese Patent No. 202871535, which includes a first bobbin, a second bobbin and a magnetic Core group.

In the patent case, the problem of the conventional transformer has been improved, and a transformer with adjustable leakage inductance is provided. However, the first line cake still needs to be pre-wound on the first bobbin, and then the first The assembly of the transformer can be completed by assembling a bobbin and the second bobbin. Therefore, the applicant of this case is based on the research and development of transformers, and finally proposed this new patent case, which is similarly used to solve the problem that the structure of the conventional transformer cannot adjust the leakage inductance value.

More specifically, the first wire 41 and the second wire 51 in the present invention are wound in a horizontal manner along a spiral line, so that the first wire 41 and the second wire 51 are wound after being finished. The first line cake 40 and the second line cake 50 are formed separately, so that the first line cake 40 and the second line cake 50 can be preliminarily modularized. Thereafter, the first line cake 40, the leakage inductance adjusting portion 60 and the second line cake 50 are sequentially stacked on the wire frame 30 to make the first sleeve hole 42 and the second sleeve hole 52. The third sleeve hole 62 is sleeved on the outer side of the socket portion 31, and the first wire cake 40, the leakage inductance adjusting portion 60 and the second wire cake 50 are respectively used by the socket portion 31 and the sleeve portion 31.

A first limiting portion 352 extends from the third sleeve hole 62 of the adjusting portion 60, and the second insulating seat 36 extends toward the third sleeve hole 62 opposite to the first limiting portion 352. The second limiting portion 362 extends the first limiting portion 352 and the second limiting portion 362 in the third sleeve hole 62 to achieve the limit effect of the leakage inductance adjusting portion 60. The leakage inductance adjusting portion 60 is effectively fixed between the first insulating seat 35 and the second insulating seat 36.

In summary, the first line cake 40 and the second line cake 50 of the present invention can be modularized, so that the first line cake 40, the leakage inductance adjusting portion 60 and the second line cake 50 can be quickly The wire frame 30 is assembled on the wire frame 30 and insulated from the iron core 20 to improve the assembly efficiency of the transformer.
