Abstract
The utility model provides a novel magnetic core which comprises two magnetic core bodies. The novel magnetic core is characterized in that the two magnetic core bodies are connected through a central column; a pair of symmetrical leading grooves for leading out coils is opened in the edge side wall of the magnetic core bodies, and electrodes for welding a circuit board are arranged at the ends of the magnetic core bodies close to the leading grooves. According to the novel magnetic core, the magnetic core central column is circular, the effective cross-section area of the central column is increased, a plurality of problems to surface mounting power inductors caused by the central column polygon shape and large size fluctuation are solved, the surface mounting power inductor overlapping performance can be improved, the core bending strength and the hem bending strength of finished products are improved, and accordingly, the product reliability is greatly improved, and during manufacturing of inductance elements, costs are greatly reduced, and benefits are improved.
Description
Technical field
The utility model relates to the magnetic ferrite magnetic core field, refers in particular to a kind of novel magnetic core.
Background technology
Current paster power inductance is general to be adopted enamel covered wire around the mode on the I-type magnetic core center pillar, but the external diameter shape of I-type magnetic core is divided: toroidal and irregular cycle, elliptical shape.When the I-type magnetic core external diameter is shaped as irregular cycle, elliptical shape, cut magnetic core product in the pin process in processing the shake action is arranged, thereby in producing, many ribs appear in post shapes, in identical product, column dimension maximum and minimum value differ 0.1-0.35mm and do not wait, large pendulum folding and the core folding intensity that affects finished product of center pillar size fluctuation, the center pillar corner angle cause paster power inductance coiling process easily break and hinder copper cash enamel-cover film, cause the short circuit of inductance finished product or open circuit.
Summary of the invention
The purpose of this utility model is to provide a kind of can overcome above-mentioned defect, improves the product yields, reduce production costs, and the novel magnetic core of increasing economic efficiency.
For achieving the above object, technical scheme provided by the utility model is: a kind of novel magnetic core, and it includes magnetic core array, it is characterized in that: described magnetic core array is two, between two magnetic core arrays, by newel, connects; On magnetic core array edge sidewall, offer a pair of symmetrically for drawing the wire lead slot of coil, the magnetic core array end is provided with the electrode for soldered circuit board near the wire lead slot place.
The cross section of described magnetic core array is for circle or have the circle of trimming.
The shape of cross section of described newel is circular.
The beneficial effects of the utility model are: the magnetic core center pillar that this programme adopts is for circular, thereby the effective cross section that has increased center pillar is long-pending, the problems that many prismatics of center pillar shape and size fluctuation are brought the paster power inductance have greatly been solved, can improve the stack performance of paster power inductance, improve core folding intensity, the pendulum folding intensity of finished product, thereby greatly improved the product reliability, and greatly reduce costs when making inductance element, increase the benefit.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is newel schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, the described novel magnetic core of the present embodiment includes magnetic core array 1, it is characterized in that: described magnetic core array 1 is two, between two magnetic core arrays 1, by newel 2, connects; The shape of cross section of the newel 2 of the present embodiment is circular.Offer a pair of symmetrical wire lead slot 3 for drawing coil on magnetic core array 1 edge sidewall, magnetic core array 1 end is provided with the electrode 4 for soldered circuit board near wire lead slot 3 places.The cross section of the magnetic core array 1 of the present embodiment is the circle with trimming, certainly, also can adopt according to actual needs circle or other geometry.Magnetic core product one end is fixed in the smelting tool consistent with shape of product, and the smelting tool is to be fixed on the direct current machine main shaft, and the other end is pushed down magnetic core product with the thimble that is less than middle column dimension.Then utilize motor 360 degree to rotate without acceptance of persons, emery wheel processing cutter 8000-10000 rev/min run up under, utilize the cam progression, product process to the operation of slotting, the magnetic core of producing by the method, center pillar is shaped as circle and center pillar size fluctuation scope is little.Thereby the effective cross section that has increased center pillar is long-pending, has solved the problems that many prismatics of center pillar shape and size fluctuation are brought the paster power inductance greatly, can improve the stack performance of paster power inductance, improve core folding intensity, the pendulum folding intensity of finished product.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection range of the present utility model.
