Abstract

The invention discloses a transformer of a small power supply. The transformer comprises skeletons, wherein each skeleton comprises a first platform and a second platform, a conducting wire is wound between the first platform and the second platform, a communicating pipe for accommodating an iron core is connected between the first platform and the second platform, a first convex column for wire hanging is arranged on the first platform, the head of the first convex column extends in the direction away from the second platform to form a first blocking rib, a second convex column for wire hanging is arranged on the second platform, a second blocking rib is arranged on the head of the second convex column, a pin is arranged at the bottom of the second platform, the pin is a columnar square pin, and the iron core comprises an upper U-shaped iron core and a lower U-shaped iron core; the number of the skeletons is two; two ends of the upper iron cores are inserted into the communicating pipes of the two skeletons, two ends of the lower iron cores are inserted into the communicating pipes of the two skeletons, and the two ends of the upper irons cores and the two ends of the lower iron cores are spliced in the communicating pipes. The transformer has the advantage that the transformer is more convenient to wind, a wound coil is more regular, and the transformer is safer.

Description

【Technical field】 [0001] The invention relates to a small power transformer. 【Background technique】 [0002] At present, transformers are used in almost all electronic products. Its principle is simple, but the winding process of transformers will be different according to different usage occasions. The high frequency of the charger makes it the direction of development, the high frequency makes the charger more miniaturized, and makes the charger enter a wider range of applications, especially in the application of high-tech fields, which promotes the miniaturization of high-tech products, portability. In addition, the development and application of chargers are of great significance in saving energy, saving resources and protecting the environment. The development direction of the charger is high frequency, high reliability, low consumption, low noise, anti-interference and modularization. Commonly used charger transformers have too high safety distance requirements, ad...
