Background technique

A large amount of different configurations of inductance electronic device are known in the prior art.Many biographies of such as transformer etc Inductive component of uniting uses the primary and secondary winding made of conductor insulated from each other.Be applied to the voltage of armature winding according to Number of turns of wire ratio between primary and secondary winding determines voltage that (dictate) is generated in secondary windings.But currently, Most slab inductor is unicoil slab inductor, and this product has the following problems: structure is simple, substantially one production Only one magnetic loop of product, performance is relatively low, is not able to satisfy high current high frequency requirements.Therefore, there are multiple flatwise coils on the market Altogether the same magnetic core structure, however the flatwise coil quantity of this inductor be it is fixed, for example, three/the tetra- of integral type A/five/six flatwise coil finished products etc., integral structure can only be used directly after making production, be can not be split.

Utility model content

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of multiple flat The high current inductor in high frequency of flat coil composition, according to needing to spell assembly and disassembly, flexibility is high, easy to use, thus Overcome the deficiencies in the prior art.

To achieve the above object, the utility model is using following technical solution:

A kind of high current inductor in high frequency of multiple flatwise coil compositions, is made of multiple inductors, each inductor Structure is identical, includes planar magnetic core and flatwise coil, and the planar magnetic core includes the upper core member that can be stacked together up and down Part and lower core element, the lower core element center are equipped with accommodation groove and newel, and the flatwise coil winds several circles around newel, The head and the tail both ends of flatwise coil are from the stretching of the two sides of lower core element and bending extends to the bottom formation patch type of lower core element Leg；The side of the lower core element is equipped with connection convex block, and the other side is equipped with gomphosis groove, and two adjacent inductors pass through that This connection convex block and gomphosis groove is installed together.

As a preferred embodiment, the flatwise coil has internal diameter and outer diameter, is albronze close to the side of internal diameter Conductor, close to the side of outer diameter be Kufil conductor, middle part is pure cu conductor, be gradually increased according to the diameter of flatwise coil, The conductivity of conductor is synchronous to be increased.

As a preferred embodiment, the outer peripheral surface of the flatwise coil covers insulating layer.

As a preferred embodiment, 5 inductors are in a row using mutual connection convex block and gomphosis groove shape.

As a preferred embodiment, the planar magnetic core is square body, and the accommodation groove is circular trough.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Scheme on inductor it is found that due to being provided with connection convex block and gomphosis groove, so that two adjacent inductors are by each other Connection convex block and gomphosis groove be installed together, that is to say can according to need rapidly by multiple inductors splice one Rise, and can fast quick-detach, flexible Application is very easy to use.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.

Specific embodiment

Please refer to figs. 1 to 4, that show the specific structures of the preferred embodiment of the utility model, are a kind of The high current inductor in high frequency of multiple flatwise coil compositions, is made of, the structure phase of each inductor 100 multiple inductors 100 It together, include planar magnetic core 10 and flatwise coil 20.It, can be with since the design of flatwise coil 20 is so that wire cross-section area is bigger Meet the conveying of high current high frequency voltage.

Wherein, the planar magnetic core 10 is formed by the magnetic permeable material of such as ferrite etc, and is wrapped in structure The upper core element 11 that can be stacked together up and down and lower core element 12 are included, is sandwiched in flatwise coil 20 therebetween.Under this 12 center of core element is equipped with accommodation groove 121 and newel 122, and the flatwise coil 20 winds several circles around newel 122, flat The head and the tail both ends of coil 20 are from the stretching of the two sides of lower core element 12 and bending extends to the bottom formation patch of lower core element 12 Formula leg 21, so directly using flat conductor as leg, remove from traditional round wires need to be arranged leg and by round wires with The process of leg welding.In the present embodiment, the planar magnetic core 10 is square body, and the accommodation groove 121 is circular trough.

The side of the lower core element 12 be equipped with connection convex block 123, the other side be equipped with gomphosis groove 124, adjacent two Inductor 100 is installed together by mutual connection convex block 123 and gomphosis groove 124.In the present embodiment, inductor in high frequency 100 quantity is 5, and 5 inductors 100 are in a row using mutual connection convex block 123 and 124 shape of gomphosis groove.In use, More inductors 100 can also be arranged according to needing, and each inductor 100 can be in the state of without splicing It is used alone.

The flatwise coil 20 has internal diameter and outer diameter, is albronze conductor 201, close to outer diameter close to the side of internal diameter Side be Kufil conductor 202, middle part is pure cu conductor 203, be gradually increased according to the diameter of flatwise coil 20, conductor Conductivity is synchronous to be increased.In this way, when electric current is flowed through from the side close to outer diameter, since outer perimeter is the several times of interior perimeter, if flat No matter inner circumferential or periphery are all made of the conducting medium of same material to flat coil 20, will cause all-in resistance of the all-in resistance than inner circumferential of periphery Greatly, so that periphery and inner circumferential form voltage difference.Therefore, the present embodiment, using the different materials for being sequentially increased conductivity from inside to outside Material, so that resistance value from the inside to the outside balances as far as possible, so that the voltage of flat wire entirety is uniform.In addition to this, described flat The outer peripheral surface of coil 20 covers insulating layer 204, and after winding lopping, the flatwise coil 20 of stacking is isolated in-between will not phase mutual conductance It is logical.

The high current inductor in high frequency 100 of the utility model is to be bolted together to form one by multiple 100 head and the tail of inductor Row, using connection convex block 123 can be with quick assembling with gomphosis groove 124 together with, can also fast quick-detach, combination multiplicity Change, it is very easy to use.Further, since coil designs different conducting mediums by interior radial outer diameter transition, so that flat wire The whole voltage homogenization of circle 20, improves the performance of inductance.

The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change Change and modify, is still within the scope of the technical solutions of the present invention.
