Embodiment Construction

[0016] A number of embodiments of the present invention will be disclosed below with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some known and commonly used structures and components will be shown in a simple and schematic way in the drawings.

[0017] A technical solution of the present invention is a transformer. More specifically, it can reduce the problems of mold errors and manual assembly differences mainly by sheathing the sleeve between the iron core set and the insulating cover and / or between the iron core set and the bobbin. The sleeve can not only solve the problem that the assembly skew of the iron core group affects the el...

Abstract

The invention relates to a transformer which comprises a reeling frame, an iron core set and a first sleeve, wherein the reeling frame comprises a body and a penetrating channel which penetrates through the body; the iron core set comprises a first iron core and a second iron core; a first tail end of the first iron core and a second tail end of the second iron core are arranged in positions close to a lateral edge of the reeling frame; the first sleeve is arranged in a first clearance between the first tail end and the second tail end, so that the first tail end and the second tail end are inserted into the first sleeve; and the first tail end is aligned with the second tail end.

Description

technical field [0001] The present invention relates to a transformer. Background technique [0002] With the advancement of technology, there are various types of home appliances. However, the voltage and power required to drive each type of appliance are different. Therefore, various transformers are required to provide different voltages and power. At present, there are two types of transformer products commonly used in the industry. One is a high-frequency transformer, which is generally a switching power supply power conversion transformer. The other is a low-frequency transformer, which is a general silicon steel sheet transformer. [0003] A known transformer includes a bobbin and a core set. The winding frame of the transformer can be used for overlapping winding of the primary winding coil and the secondary winding coil. The iron core group is partly installed on the winding frame, so that the iron core group and the primary winding and secondary winding wound o...
