Abstract
An assembled multi-polar magnetic core consists of a top plate, a bottom plate and a plurality of magnetic core columns, wherein all the magnetic core columns are arranged between the top plate and the bottom plate, and each magnetic core column is of a whole structure or a spilt structure; thread grooves are arranged on the bottom plate, and the number of the magnetic core columns can be arranged according to needs. As a plurality of magnetic circuits are assembled together and the spilt assembly structure is adopted, and all the magnetic core columns are arranged between the top plate and the bottom plate, the magnetic core with the assembled structure not only can optimize the distribution of the magnetic circuits, reduce the volume of electronic components, expand the functions of the electronic components and meet the requirements of miniaturization and multi-function of electronic devices, but also can improve the electromagnetic interference resistance capacity of the electronic components assembled together and reduce the electromagnetic interference generated by the electronic components to the outside simultaneously.
Description
Technical field:
The present invention relates to a kind of multi-pole combined magnet core that a plurality of inductance, transformer or other electronic devices and components are installed that is used for.
Background technology:
Fast development along with electronics industry, high-performance, miniaturization, multi-functional be electronic equipment developing direction from now on, in order to reach this purpose, the common way of people is that several electronic devices and components are made up intensive installation simply, like this, though volume dwindles to some extent, there is bigger interference between each components and parts mutually, and assembling is complicated, cost is high, and performance is also not ideal enough.If a plurality of components and parts that are provided with the difference in functionality of magnetic core can be combined, just can improve packaging density, the reduced volume of components and parts, reduce cost significantly, further accelerate the development speed of electronic equipment to high-performance, miniaturization, multifunctional direction.By retrieval, at present, relevant this respect does not also have relevant report, still is in blank both at home and abroad in this field.
Summary of the invention:
In order to satisfy people's above-mentioned requirements, the object of the invention provides a kind of multi-pole combined magnet core.
The technical solution used in the present invention is:
Described multi-pole combined magnet core, it is made up of top board 1, base plate 2 and several core post 3, and all core post 3 all are arranged between top board 1 and the base plate 2.
Embodiment one, described core post 3 is an overall structure, an end of core post 3 is fixedlyed connected with top board 1 or base plate 2.
Special case, described core post 3 is integrated with top board 1 or base plate 2.
Embodiment two, core post 3 is for dividing body structure, and core post 3 is made up of last core post 31 and following core post 32, and last core post 31 is fixedlyed connected with top board 1, and following core post 32 is fixedlyed connected with base plate 2.
Special case, last core post 31 and top board 1 are integrated, and following core post 32 is integrated with base plate 2.
Embodiment three, in all core post 3, some core post 3 is an overall structure, another part core post 3 is for dividing body structure, divide the core post 3 of body structure to form by last core post 31 and following core post 32, last core post 31 is fixedlyed connected with top board 1 or is integrated, and following core post 32 is fixedlyed connected with base plate 2 or be integrated; One end of one-piece magnetic core post 3 is fixedlyed connected with top board 1 or base plate 2, and is perhaps integrated with top board 1 or base plate 2.
Special case divides the core post 3 of body structure to be made up of last core post 31 and following core post 32, and is integrated with top board 1 and base plate 2 respectively; Integrally-built core post 3 is integrated with base plate 2.
In all embodiments, on base plate 2, be provided with threading hole slot 4, the quantity of described core post 3 is 3～1000.
Because a plurality of magnetic circuits are combined, and take the split package assembly, all core post all are arranged between top board and the base plate, the magnetic core of this combining structure not only can be optimized magnetic circuit and distribute, dwindle the volume of electronic building brick, expanded the function of electronic building brick, satisfied the miniaturization of electronic equipment, multi-functional requirement, and can improve the electronic building brick opposing electromagnetic interference capability of combining, reduced the electromagnetic interference that this electronic building brick externally produces simultaneously.
