Abstract
Embedment parcel formula switching mode power supply transformer, including transformer skeleton coil, plastic housing is arranged in to transformer skeleton coil, fills the casting glue in the plastic housing to transformer skeleton coil fixed seal. The utility model discloses utilize the casting glue wrap up completely on the transformer exposing of short circuit probably to appear electrified, the emergence of the short circuit phenomenon having stopped completely to cause because of steam has simple structure, convenient to use and safe and reliable's advantage.
Description
Technical field
This utility model relates to a kind of transformator, is specifically related to a kind of embedding packaging type switching mode power supply transformer.
Background technology
At present, mains transformer is widely used to household electrical appliance, electronic machine, medical communication equipment and automation control system, the function of mains transformer is power transmission, voltage transformation and is dielectrically separated from, as a kind of main soft magnetism electromagnetic component, and Power Electronic Technique is widely used in power technology.Almost will use in all of electronic product, its principle is simple but technique for coiling of according to different use occasion (different purposes) transformators can be different requirement.
In existing technique, general switching mode power supply transformer uses the Open architecture without embedding, so will be affected in specific environment, such as easily causes transformator in moister environment and burns out because of short circuit.
Utility model content
This utility model provides a kind of embedding packaging type switching mode power supply transformer, to solve the problem easily occurring short circuit in wet environment that prior art exists.
This utility model includes transformer framework coil, solves its technical problem employed technical scheme comprise that transformer framework coil and is placed in plastic shell, and in plastic shell, perfusion casting glue is to transformer framework coil fixing seal.
Above-mentioned casting glue is silica gel or epoxy resin or polyurethanes glue.
This utility model utilize on the fully wrapped around transformator of casting glue be likely to occur short circuit expose charged point, stopped the generation of the short circuit phenomenon caused because of steam completely, there is simple in construction, easy to use and safe and reliable advantage.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1 plastic shell, 2 transformer framework coils, 3 casting glues in figure.
Detailed description of the invention
