Abstract
The utility model relates to switch power technologies.The utility model is to solve the problems, such as that existing Switching Power Supply be easy to cause magnetic element to damage because of working environment humidity, provide a kind of damp-proof type Switching Power Supply, its technical solution are as follows: damp-proof type Switching Power Supply, including magnetic element, power module and shell, magnetic element is fixedly connected with power module, enclosure lid magnetic element, outer casing bottom and power module are tightly connected.By installing insulating material housing additional in the magnetic element periphery of Switching Power Supply, gap between outer casing bottom and power module uses encapsulation process, magnetic element is fully sealed shell, realizes that magnetic element and external environment are completely isolated, is particularly suitable for using in long-term wet environment.
Description
Technical field
The utility model relates to power circuit technical field, in particular to a kind of Switching Power Supply.
Background technique
The magnetic element of Switching Power Supply is usually made of winding and magnetic core, it is energy storage, energy conversion and electrical isolation institute
Indispensable power electronic devices mainly includes transformer and inductor two major classes.In nearly all power circuit, it all be unable to do without magnetic
Property element, magnetic element is one of most important component part of power electronic technique.The magnetic elements such as electronic transformer, inductor
Although more only seeming unremarkable small part, in the products such as new-energy automobile, LED power, photovoltaic DC-to-AC converter but
It is to play indispensable role.In practical applications, Switching Power Supply is frequently necessary to work in long-term moist environment, such as
Intelligent closestool, magnetic element is because wet environment is easy to appear the foreign matters such as condensation droplet and forms magnetic element short circuit or gradually become rusty
Erosion, can be such that Switching Power Supply damages, and when serious, the safety devices creepage distance of insulation such as transformer is shortened, has and causes electric shock
Security risk.
Existing Switching Power Supply processing mode is package insulating tape, or to the processing of magnetic element surface encapsulating, is held in this way
Gap cavity is easily left, there are certain failure probabilities, cannot prevent magnetic element band due to wet environment damages completely
The performance issue and security risk come.
Utility model content
The purpose of this utility model is to solve existing Switching Power Supply because working environment humidity be easy to cause magnetic element to damage
Bad problem provides a kind of damp-proof type Switching Power Supply.
The technical scheme adopted by the utility model to solve the technical problem is as follows: damp-proof type Switching Power Supply, including magnetic member
Part, power module and shell, the magnetic element are fixedly connected with power module, enclosure lid magnetic element, outer casing bottom with
Power module is tightly connected；
The shell is made of insulating materials.
Specifically, the outer casing bottom with power module sealed connection is connect using sealant pouring and sealing.
Further, the interior of shell is also fixedly connected with magnetic element.
Specifically, the interior of shell is provided with buckle；
The magnetic element is provided with bayonet corresponding with buckle.
Optionally, the gap section encapsulating filling between the interior of shell and magnetic element, shell and magnetic element shape
It is into a single integrated structure.
The utility model has the beneficial effects that in the utility model, by outside the magnetic element of Switching Power Supply
Installation insulating material housing is enclosed, the gap between outer casing bottom and power module uses encapsulation process, and shell is complete by magnetic element
It is hermetically sealed, realize that magnetic element and external environment are completely isolated, magnetic element will not be because of the hair that works in wet environment for a long time
Raw damage.
Detailed description of the invention
Fig. 1 is the utility model damp-proof type switching power supply structure schematic diagram；
Fig. 2 is the vertical cross-section diagram of the utility model damp-proof type Switching Power Supply AA ' along Fig. 1；
Wherein, 1 is shell, and 2 be magnetic element, and 3 be power module.
Specific embodiment
Below with reference to examples and drawings, the technical solution of the utility model is described in detail.
Damp-proof type Switching Power Supply described in the utility model, including magnetic element, power module and shell, wherein magnetic member
Part is fixedly connected with power module, enclosure lid magnetic element, and outer casing bottom and power module are tightly connected, and shell here is
Using made of insulating materials；By installing insulating material housing, outer casing bottom and electricity additional in the magnetic element periphery of Switching Power Supply
Gap between source module uses encapsulation process, and magnetic element is fully sealed shell, realizes that magnetic element and external environment are complete
Full isolation, magnetic element will not be damaged because of working in wet environment for a long time, and Switching Power Supply will not be because of existing for a long time
It works in wet environment and generates performance issue and security risk.
Embodiment
The damp-proof type Switching Power Supply of the utility model embodiment, as shown in Fig. 2, include magnetic element 2, power module 3 and
Shell 1, magnetic element 2 are fixedly connected with power module 3,1 the cover magnetic element 2 of shell, the bottom of shell 1 and power module 3
Between gap sealing connection, encapsulating processing can be used, shell 1 and power module 3 is made to form the entirety of a sealing, this implementation
Shell 1 in example is made of phenolic resin, is one kind of plastics, has the characteristics that light, insulation effect is good.
In the present embodiment, shell 1 is also fixed with magnetic element 2, and a kind of embodiment is to be internally provided with card in shell 1
Button, magnetic element 2 are provided with bayonet corresponding with buckle, block after 1 the cover magnetic element 2 of shell；Another embodiment is
After 1 the cover magnetic element 2 of shell, the gap section encapsulating between 1 inside of shell and magnetic element 2 is filled, shell and magnetic
Property element formed integral structure.In this way, shell 1 would not fall off because of vibration.
Magnetic element 2 is fully sealed shell 1, and magnetic element 2 and external environment are completely isolated, when Switching Power Supply exists for a long time
When working in wet environment, magnetic element remains drying, will not be damaged because of external environment, avoid wet environment
To Switching Power Supply bring performance issue and security risk.
