Abstract
The utility model provides a high -frequency switching mode power supply transformer, including skeleton, solid magnetic core, coil, the pin of coiling on the skeleton on the skeleton of cover, its characterized in that: the skeleton of the vice limit position of transformer is " L " font form, through the extension of pin on the skeleton, draws back the distance of the vice limit of transformer pin and magnetic core, when having dwindled whole high -frequency switching mode power supply transformer volume, guarantees the safe distance on former pair of limit. The utility model discloses simple structure, small, low in manufacturing cost, transformer stable performance.
Description
Technical field
The utility model belongs to transformer technology field, is specifically related to a kind of high-frequency switch power transformer.
Technical background
At present, the electronic product used in life gets more and more, so also very frequent for the use of power supply adaptor etc., along with the development of power supply industry, while requiring high-performance and safety, power supply appearance requirement is improved constantly, more and more toward small size, high safety, high-performance trend development.Usually can reaching by the volume reducing transformer the object reducing power volume, for reaching above requirement, therefore needing to improve high-frequency switch power transformer.
High-frequency switch power transformer is slightly different with other product transformers, due to frequent use, very high to the security requirement of transformer, and now widely used power transformer has EE13 horizontal type transformer, but still there is the potential safety hazards such as safe distance is less than normal.
Utility model content
Technical problem to be solved in the utility model is: when ensureing electric property safety and stability, and provide a kind of structure simple, volume is little, low cost of manufacture, the high-frequency switch power transformer of stable performance.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of high-frequency switch power transformer, comprise skeleton, the magnetic core be fixed on skeleton, the coil be wound on skeleton, pin, it is characterized in that: the skeleton of transformer secondary position Chengs “ ∟ " word shape; by the extension of pin on skeleton; pull open the distance of transformer secondary pin and magnetic core; while reducing whole high-frequency switch power transformer volume, ensure the safe distance of former secondary.
The distance of transformer secondary at least two pins and magnetic core is pulled open.
The described magnetic core be fixed on skeleton, in " mountain " font, inserts from skeleton both sides and is fixedly connected with.
In one word, the utility model has a few quantum jump point technically: structure is simple, volume is little, low cost of manufacture, stable performance.
What current power supply adopted usually is EE13 horizontal type transformer, but its to there is safe distance less than normal, then can cause safe distance wait series of security questions not when reducing volume of transformer.Volume of transformer cannot diminish, and cannot adapt to the miniaturized market demand.Compared with existing power supply miniature transformer structure, described high-frequency switch power transformer, the structure of skeleton is improved, “ ∟ is Chenged in skeleton secondary position " word shape; the design extended by pin on skeleton; pull open the distance of transformer secondary at least two pins and magnetic core, while reducing whole high-frequency switch power transformer volume, the safe distance of former secondary can be ensured.And this high-frequency switch power transformer structure is simple, be convenient in enormous quantities making and production.Reduce the area that high-frequency switch power transformer is shared in the circuit board, reach the object reducing whole power volume.

Embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model provides a kind of high-frequency switch power transformer to embodiment of the present utility model, comprises skeleton, the magnetic core be fixed on skeleton, the coil be wound on skeleton, pin 1.Magnetic core is fixed in skeleton periphery, pin is located at bottom skeleton, and coil is connected with pin by the wire lead slot on skeleton around with on skeleton, and skeleton base is provided with wire lead slot.
See Fig. 1, the skeleton 2 Cheng “ ∟ of transformer secondary position " word shape, adopt single injection-molded technique ， “ ∟ " word shape skeleton makes transformer secondary part Pin locations extend, the distance of transformer secondary pin and magnetic core is pulled open, and can ensure former secondary safe distance.During concrete enforcement, the distance of transformer secondary at least two pins and magnetic core is pulled open.The distance of preferred transformer secondary two pins and magnetic core is pulled open.
The described magnetic core be fixed on skeleton, in " mountain " font, inserts from skeleton both sides and is fixedly connected with.
Compared with existing power supply miniature transformer structure, described high-frequency switch power transformer, improves the structure of skeleton, skeleton secondary position in "
l" word shape, by the extension of pin position on skeleton, pull open the distance of transformer secondary pin and magnetic core, while reducing whole high-frequency switch power transformer volume, the safe distance of former secondary can be ensured.And this high-frequency switch power transformer structure is simple, be convenient in enormous quantities making and production.Reduce the area that high-frequency switch power transformer is shared in the circuit board, reach the object reducing whole power volume.
The utility model is not when affecting high-frequency switch power transformer electrical safety performance, improve for high-frequency switch power transformer skeleton secondary, solve and reduce high-frequency switch power transformer volume and bring inadequate the caused security hidden trouble of safe distance.This high-frequency switch power transformer has that structure is simple, volume is little, low cost of manufacture, stable performance, the advantage such as workable.
Comprise according to high-frequency switch power transformer described in the utility model: highly, thickness, length and direction, color etc., any one form wherein, also can select any one material making transformer.
It is understood that above-described embodiment is just to explanation of the present utility model.Instead of to restriction of the present utility model, any utility model do not exceeded in the utility model enforcement scope is created, and all falls within protection range of the present utility model.
