Abstract
The utility model discloses a kind of high-current inductor, comprise square core, the surface of three sides in interconnected four sides of square core has breach, square core is divided into interconnected two little magnetic cores by three breach, between two little magnetic cores, embed a snap ring that is first " protruding " font, snap ring embeds after two little magnetic cores, will open three sides jaggy and seal, and it is consistent with the appearance preservation of the square core before gap to make to seal rear square core.The utility model can increase the effective area of magnetic core, improves inductance and resistance to bias current ability in the situation that of identical prerequisite, thereby reduces core loss, improves power-efficient.In addition, the utility model can be made ladder breath as required, outputs a gap stating in four sides the not bottom of that side of gap, and regulate according to specific needs the degree of depth in gap, when ensureing underloading, inductance value is large, and efficiency is high, avoids magnetic core saturated fully loaded time.
Description
Technical field
The utility model relates to electric power firmware field, particularly a kind of high-current inductor.
Background technology
Inductance element is components and parts very important in electronic industry, and traditional electrical sensing unit is to wind the line and make in magnetic material element; Another kind of inductance element is at the made cladding of coil outer cladding one permeability magnetic material, thereby forms inductance element.Traditional inductance element, is formed by two magnetic cores and a coil combination one on the other, and the next magnetic core is provided with a groove, and for accommodating coil, upper magnetic core is corresponding with it to be covered, more gluingly connect through putting, the technique such as baking, make two magnetic cores be combined into a cladding., can there is space two magnetic core combinations place in this inductance element, this is a very large magnetic conduction defect, can produce thus vibration and noise, also can cause magnetic loss to strengthen, and affects the quality factor (quality factor is called for short Q value) of inductance.Meanwhile, inductance element is in the time making, and owing to doing breath with special bead, cost of manufacture is high.In addition, existing inductor is difficult to do ladder inductance, and when underloading, inductance is lower, and power-efficient is low, and easily saturated when large electric current.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of high-current inductor, has ladder breath function, increases dielectric capacity, increases inductance value, reduces costs, and raises the efficiency.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of high-current inductor, comprise square core, in interconnected four sides of described square core, on the surface of three sides wherein, have breach, and these three breach interconnect and make square core be divided into interconnected two little magnetic cores, between described two little magnetic cores, embed a snap ring that is first " protruding " font, the thickness of described snap ring is all lower than the thickness of three breach, and snap ring embeds after two little magnetic cores, in slightly outstanding described four sides, the bottom surface of described snap ring the side of gap not.
Further, described snap ring embeds after two little magnetic cores, will open three sides jaggy and seal, and it is consistent with the appearance preservation of the square core before gap to make to seal rear square core.
Further, describedly will open three sides jaggy while sealing, and adopt the mixture being formed by magnetic conduction powder and epoxy resin as encapsulant.
Further, in described four sides, a gap is not outputed in the bottom of that side of gap.
Further, the breach that has opened with two relative sides in described gap is communicated with.
Further, described square core material is ferrite.
The beneficial effects of the utility model are:
The utility model adopts a kind of high-current inductor, comprise square core, the surface of three sides in interconnected four sides of square core has breach, square core is divided into interconnected two little magnetic cores by three breach, embeds a snap ring that is first " protruding " font between two little magnetic cores.The utility model can increase the effective area of magnetic core, improves inductance and resistance to bias current ability in the situation that of identical prerequisite, thereby reduces core loss, improves power-efficient.The utility model is simplified inductance technological process, reduce costs, can make as required ladder breath, output a gap stating in four sides the not bottom of that side of gap, can regulate according to specific needs the degree of depth in gap, when ensureing underloading, inductance value is large, and efficiency is high, avoids magnetic core saturated fully loaded time.
Brief description of the drawings
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of snap ring described in the utility model;
Fig. 3 is that square core described in the utility model is outputed the structural representation behind three breach and gap;
Fig. 4 is the structural representation after breach sealing described in the utility model.
Embodiment
Shown in Fig. 1-Fig. 4, the utility model provides a kind of high-current inductor, comprise square core, in interconnected four sides of described square core, on the surface of three sides wherein, have breach, and these three breach interconnect and make square core be divided into interconnected two little magnetic cores, between described two little magnetic cores, embed a snap ring that is first " protruding " font, the thickness of described snap ring is all lower than the thickness of three breach, and snap ring embeds after two little magnetic cores, the side of gap not in slightly outstanding described four sides, the bottom surface of described snap ring.
Fig. 1 has shown that snap ring embeds the schematic diagram after two little magnetic cores, in figure, shows, the thickness of snap ring is less than the thickness of breach, and after embedding, and the bottom surface of snap ring is a little more than the side of gap not in described four sides.The structure of described snap ring is with reference to shown in Fig. 2, and described square core is outputed three structures after breach with reference to shown in Fig. 3.Afterwards, the utility model will be opened three sides jaggy and seal, and it is consistent with the appearance preservation of the square core before gap to make to seal rear square core.In order to ensure sealing effectiveness, split three sides jaggy while sealing, adopt the mixture being formed by magnetic conduction powder and epoxy resin as encapsulant.
The utility model can increase the effective area of magnetic core, improves inductance and resistance to bias current ability in the situation that of identical prerequisite, thereby reduces core loss, improves power-efficient.The utility model is simplified inductance technological process, reduces costs.
In addition, can make as required ladder breath, output a gap stating in four sides the not bottom of that side of gap, can regulate according to specific needs the degree of depth in gap, when ensureing underloading, inductance value is large, and efficiency is high, avoids magnetic core saturated fully loaded time.
For further in order to be effective, described gap is in the time arranging, and the breach that has opened with two relative sides in described gap is communicated with.
Side's row magnetic core of the present utility model is made up of ferrite, and encapsulant is made up of magnetic conduction powder and epoxide resin.
The actual test of herbal classic, initial inductance can promote more than 60%, and saturation current improves approximately 15%, at least saves more than 10% cost simultaneously.
The above, be preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
