The utility model discloses a flat flat line encloses the design that front and back pin opposite direction bent, comes the binding face of co -product and base plate, can save the base material, and the coil is the conduct electrode directly, simple process, and easy the operation, occupation space is little, processes manual work and material cost greatly reduced.
Description
Technical field
The utility model relates to inductor, relates to a kind of vertical thin high-current inductor specifically.
Background technology
Inductance is as energy storage and filter element, be widely used in the electronic device, along with the development of science and technology, inductor is more and more tending towards miniaturized, volume weight requires more and more stricter, especially at computer, air-conditioning and communication products, employ the withstand large current filtering inductance of a large amount of high frequency in the electronic equipments such as wireless base station power supply, inductance has that operating current is large, number of ampere turns is high, have the advantages such as common chip inductor encapsulation.
The vertical high-current inductor of tradition coiling needs bonding base bottom magnetic core to come as electrode surface mostly, general technology is that after coiling, coil is assembled bonding with magnetic core, after drying, coil two is welded with the electrode slice of base by bending, bonding by needs glue between magnetic core with base, baking forms, technics comparing is complicated, loaded down with trivial details, material cost is high, base takes up room greatly, design also needs fully take into account magnetic core, coil, cooperation between base three, because assembling cooperation causes, product is bad accounts for major portion.The utility model design can effectively solve these difficult problems.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of vertical thin high-current inductor.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of vertical thin high-current inductor, this inductor comprises magnetic core, lower magnetic core and be arranged on magnetic core, inductance coil between lower magnetic core, described inductance coil is by after the coiling of platypelloid type copper lines, two the flat pins up and down stretched out are bent into 90 degree, and two flat pin directions are relative direction, the described upper magnetic core side of being body, lower magnetic core is provided with storage inductance coil groove, one is arranged for the reference column of fixed inductance coil in the middle part of groove, reference column in the middle part of described groove controls inductance value by grinding air gap.
Further, described lower magnetic core groove is provided with two breach placing flat pin.
Further, described upper magnetic core, lower magnetic core, coil are adhesively fixed by epoxy glue, after cooperation, and the global shape side of being body.
Further, two flat pins of described inductance coil are exposed to the upper magnetic core after covering, lower magnetic core is outside, and the end of its bending part is close on the sidewall of magnetic core.
Further, described lower magnetic core two raised brim height is identical, and in guarantee, smooth covering be close to by magnetic core, lower magnetic core.
Further, described inductance coil bending length is greater than the height in spiral space, extends to the bottom on magnetic core, and the end of firm coil uses as electrode, and the flatness of control electrode in the reasonable scope, can not tilt.
Relative to prior art, the beneficial effects of the utility model are: the utility model is by the design of pin rightabout bending before and after flatwise coil, carry out the binding face of co-product and substrate, submount material can be saved, coil is directly as electrode, and technique is simple, easy to operate, take up room little, the artificial and material cost of processing reduces greatly.
