Description
Technical field
The utility model relates to a kind of slab inductors.
Background technique
Inductance is widely used in the electronic device as energy storage and filter element, with the development of science and technology, inductance
Device increasingly tends to minimize, and volume weight requires to be increasingly stringenter, especially in electronic equipments such as computer, air-conditioning and communication products
The middle high current filter inductance for having used a large amount of high frequencies, since its electric current is big, number of ampere turns is high, and requires small size, has common
Chip inductor the characteristics of.Current many computer main boards, circuit board of mobile phone, air-conditioning control panel are made using heavy-current inductor group column
Filter circuit, stability with super strength, but the structure based on existing heavy-current inductor, after through a long time use, inductance is easy
Aging, resistance increase, magnetic permeability reduces, eddy-current loss increases and susceptible interference.Noise is larger, and thermal diffusivity is poor.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of slab inductors, and noise is small, and heat-sinking capability is strong, manufacture
At low cost, product using effect is stablized.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of slab inductor, including FERRITE CORE and winding, the winding are made of copper sheet, FERRITE CORE and copper sheet
Attaching, the two side ends of FERRITE CORE are equipped with air gap, and the periphery that air gap is located on FERRITE CORE is provided with permanent magnet, this is forever
Magnet is fixed on FERRITE CORE by epoxy resin glue, and copper sheet attaching has copper foot.
The FERRITE CORE is ER type magnetic core.
The winding is made of copper sheet coiling multi-layer winding, and insulating layer is equipped between two layers adjacent of winding.
The winding is formed using copper sheet through spot welding and centre tap series combination.
The FERRITE CORE bottom surface is equipped with promise U.S. paper.
The long side position that the FERRITE CORE is connect with permanent magnet adheres to epoxy resin glue.
The utility model noise is small, and heat-sinking capability is strong, and manufacturing cost is low, and product using effect is stablized, the whole body of product
Product is smaller.
Detailed description of the invention
Attached drawing 1 is the utility model schematic view of the front view；
Attached drawing 2 is the utility model side structure schematic view；
Attached drawing 3 is the utility model backsight structural representation.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As shown in attached drawing 1,2 and 3, the utility model discloses a kind of slab inductor, including FERRITE CORE 1 and around
Group, the winding are made of copper sheet 4, FERRITE CORE 1 and 4 attaching of copper sheet, and the two side ends of FERRITE CORE 1 are equipped with air gap, iron
Periphery on ferrite core positioned at air gap is provided with permanent magnet 3, which is fixed on ferrite by epoxy resin glue 2
On magnetic core 1,4 attaching of copper sheet has copper foot 5.By opening up air gap on FERRITE CORE, heat-sinking capability is improved, noise, benefit are reduced
With permanent magnet, magnetic saturation is reduced, to improve the overall performance of inductance.
The FERRITE CORE is ER type magnetic core.
The winding is made of copper sheet coiling multi-layer winding, and insulating layer is equipped between two layers adjacent of winding.Winding uses copper
Piece is formed through spot welding and centre tap series combination.Entire winding is composed using copper sheet with insulating layer closed assembly mode.Pass through
The structure, the design method of this structure compare small in size 1/2 or so of conventional products, greatly save the cost of complete machine.
1 bottom surface of FERRITE CORE is equipped with promise U.S. paper 6, plays a certain protective role.
The long side position that the FERRITE CORE is connect with permanent magnet adheres to epoxy resin glue, along the long side of permanent magnet
Direction sets epoxy resin glue, it is ensured that permanent magnet is firm to be fixed on FERRITE CORE.
It should be noted that it is practical new to be not limited to this above is only the preferred embodiment of the utility model
Type, although the utility model is described in detail referring to embodiment, for those skilled in the art, still
It can modify to technical solution documented by 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 protection scope of the utility model.
