Abstract
The utility model discloses a kind of PCB transformers, including pcb board and transformer, the transformer includes winding and magnetic core, the winding welding of the transformer is inside pcb board, the pin of winding is welded on the both ends of pcb board, for magnetic core by glue and pcb board fixed bonding, which is 18 laminates of 3.7mm thickness, and the specification size of 32x20x10mm may be selected in magnetic core.The utility model overall dimensions smaller, operation is convenient, and easy to operate, client is easy for installation, and it is big to bear electric current.
Description
Technical field
The utility model is related to a kind of PCB transformers.
Background technology
For PCB flat surface transformers using the track on printed circuit board as winding, printing line winding is known as PCB windings,
It is the flat surface transformer being most widely used at present.Conventional transformer winding is connected with circuit board by the pin on skeleton
, and PCB flat surface transformers do not use skeleton, winding output end can be PCB plates（The part not covered by magnetic core）On
Pad can also be contact pin pin.
EE types magnetic core is typically assembled together by current PCB transformers with pcb board, and EE type magnetic cores are mounted in pcb board table
The size in face, entire product is larger, can occupy more space, and assembly performance is not firm enough.
Invention content
The technical problem to be solved by the present invention is to provide a kind of PCB transformers, appearance and size smaller, operation is convenient,
Easy to operate, client is easy for installation, and it is big to bear electric current.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of PCB transformers, including pcb board and transformer, the transformer include winding and magnetic core, the transformer around
Group is arranged in inside pcb board, and the pin of winding is welded on the both ends of pcb board, and magnetic core passes through glue and pcb board fixed bonding.
The magnetic core is installed in the surface of pcb board.
The glue is epoxy resin.
The part that the magnetic core is contacted with pcb board is each coated with glue.
The pcb board is 18 laminates of 3.7mm thickness.
The magnetic core is arranged in the central area of pcb board.
The utility model keeps the space availability ratio of product high, makees by the way that each winding of transformer to be located to the inside of pcb board
Industry is convenient, and easy to operate, client is easy for installation, and it is big to bear electric current.
Description of the drawings
Attached drawing 1 is the utility model main structure diagram；
Attached drawing 2 is the utility model overlooking structure diagram.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in figure 1 and 2, the utility model discloses a kind of PCB transformers, including pcb board 3 and transformer, the change
Depressor includes winding and magnetic core 1, and for the winding welding of the transformer inside pcb board 3, the pin of winding is welded on pcb board 3
Both ends, magnetic core 1 pass through epoxy resin glue 2 and 3 fixed bonding of pcb board.By assembling each winding of transformer in pcb board
Inside promotes the space availability ratio of product, the smaller that can do the shape of entire product.
The magnetic core 1 is installed in the surface of pcb board 3, which is installed in the central area of pcb board.
In addition, the part that the magnetic core is contacted with pcb board is each coated with glue, it is ensured that magnetic core and pcb board are bonded,
The epoxy resin being capable of high temperature resistant.
The pcb board is 18 laminates of 3.7mm thickness, and magnetic core is the EE types of 32x20x10, and the pin of each winding is all in PCB
It is welded in both ends in plate manufacturing process.
Each winding of transformer by being directly arranged at the inside of pcb board by the utility model, to save external sky
Between, enable to the apparent size of entire product to be made smaller.Magnetic core is fixed by heat safe epoxy resin, and assembly is more firm
It leans on.Weight greatly reduces, and using effect is stablized, efficient.It is easy for installation.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
