Abstract
The utility model provides a laminated sheet magnetic bead which includes a plurality of loops that are isolated; a plurality of loops share an end electrode and are connected in parallel and integrated inside the magnetic bead; the laminated sheet magnetic bead integrates a plurality of groups of loops inside the magnetic bead by adopting an parallel connection and integration structure; the integral resistance is reduced; the rated current of the bead is greatly improved; a plurality of beads do not to be connected in parallel; the problem of not matching between laminations caused by overlarge section area of a lead can be effectively avoided and the rate of lamination cracking or short current caused by the problem can be reduced.
Description
[technical field]
The utility model relates to a kind of lamination sheet type magnetic bead, relates in particular to a kind of high-power lamination sheet type magnetic bead.
[background technology]
As shown in Figure 1, lamination sheet type magnetic bead 1 ' commonly used is single coil a 2 ' structure, and magnetic bead 1 ' rated current is limited by the size of magnetic bead sectional area of wire, can not reach very high.In circuit design,, adopt a plurality of magnetic bead 1 ' mode in parallel, cause the increase with element employing amount of reducing in wiring board space usually for to satisfy the high-power requirement at power supply position.
For the rated current that improves magnetic bead need increase sectional area of wire.Cause not matching between layer and the layer easily but increase sectional area of wire, the damage of cracking or interlayer insulating film between cambium layer, road or short circuit thereby cambium layer splits, rate of finished products is lower, especially for the wet method laminated process.Therefore, this design can not be applicable to all technologies, and can not deal with problems fully.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of lamination sheet type magnetic bead, and it can reduce slabbing or short circuit that interlayer does not match and causes.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lamination sheet type magnetic bead is provided, comprises a plurality of isolated coils, described a plurality of coils are same termination electrode altogether; Described many group coils from parallel connection of coils are integrated in magnetic bead inside.
Compared with prior art, above-mentioned lamination sheet type magnetic bead adopts integrated morphology in parallel, to organize coil more and be integrated in magnetic bead inside, overall electrical resistance reduces, improved the rated current of magnetic bead greatly, do not need a plurality of magnetic bead parallel connections, can effectively avoid the excessive interlayer mismatch problem that causes of sectional area of wire, reduced the slabbing that therefore causes or the probability of short circuit.

[embodiment]
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Seeing also Fig. 2 to Fig. 5, is a preferred embodiment of the utility model lamination sheet type magnetic bead, and described magnetic bead 1 comprises many group coils 2, and 2 parallel connections of described many group coils are integrated in the inside of magnetic bead 1, can greatly improve the rated current of whole magnetic bead 1.Described many group coil 2 shared termination electrode (not shown)s, isolated between the described coil 2.
Parallel way between described many group coils 2 has vertical parallel connection, level is in parallel or make up three kinds of parallel waies.
Please consult Fig. 2 and Fig. 3 once more, described vertical parallel way is meant that many group coils 1 are arranged above and below, and will organize coil 2 stacked on top parallel connections in vertical direction by laminated process more, isolate fully with the insulating barrier (not shown) between the described coil 2 or not exclusively isolate.If the D.C. resistance of single coil 2 is designated as R
L, adopt this parallel-connection structure can make the D.C. resistance of magnetic bead be reduced to 1/2R
L, improved the rated current of product relatively.
Please consult Fig. 4 once more, described horizontal parallel way is meant that many group coils 1 are horizontal, and will organize the parallel connection of coil level in the horizontal direction by laminated process more, isolates fully with insulating barrier between the described coil 2 or not exclusively isolates.Many group coils 2 are in parallel in the horizontal direction, and the D.C. resistance of magnetic bead is reduced to 1/2R
L, improved the rated current of product relatively.
Please consult Fig. 5 once more, described combination parallel way is meant vertical parallel way and horizontal parallel way is combined, and will organize coil 2 stacked on top parallel connections in vertical direction more, and will organize coil 2 stacked on top parallel connections in the horizontal direction more.Level and the integrated magnetic bead of vertical parallel-connection structure combination, main feature are how group coils 2 can easier reach needed rated current respectively in level and vertical direction parallel connection.
Above-mentioned lamination sheet type magnetic bead adopts integrated morphology in parallel, to organize coil 2 more and be integrated in magnetic bead 1 inside, overall electrical resistance reduces, improved the rated current of magnetic bead 1 greatly, do not need a plurality of magnetic bead parallel connections, the excessive interlayer mismatch problem that causes of sectional area of wire be can effectively avoid, the slabbing that therefore causes or the probability of short circuit reduced.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
