Abstract
The invention relates to a high-frequency inductor, which comprises an annular magnetic core, a printed circuit board and an insulating sheet, wherein the printed circuit board is in a rectangular body; a round through hole is arranged on the surface of the rectangular body; the bottom surface and two lateral surfaces at four corners of the rectangular body are respectively coated by one layer of copper sheet; semicircular grooves are respectively arranged on the copper sheets on the two symmetrical lateral surfaces; the annular magnetic core is adhered in the round through hole in the printed circuit board; four weld legs of the annular magnetic core are respectively arranged in four semicircular grooves and are welded together with the four copper sheets; and the insulating sheet is stuck at the top of the annular magnetic core. The high-frequency inductor has the beneficial effects that: due to the use of the printed circuit board which has the same height with the wound magnetic ring and is provided with the round through hole, the height of the product is minimized; and meanwhile, the printed circuit board is produced without opening a die, so that the supply of small-batch products to customers becomes possible and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of field of electronic devices, particularly a kind of inductor in high frequency that is used for electronic equipment.
Background technology
Inductor in high frequency in the electronic equipment under the prerequisite of guaranteed performance, requires its size more and more littler, and especially height is for mobile phone, this series products of panel computer, harsher to the requirement for height of inductor.Mostly the structure of present inductor in high frequency is coiling on " I-shaped " magnetic core, bottom stickup metal electrode.Because the magnetic circuit of " I-shaped " magnetic core is open, for reaching the requirement of inductance value, use larger-size magnetic core; " I-shaped " magnetic core is made flat pattern, and the production difficulty is big, qualification rate is low, and therefore mostly " I-shaped " magnetic core is square, and height can not meet the demands.Use toroidal core, have flat ceiling advantage, but need be placed on the base plate of metal electrode, highly still unsatisfactory.
Summary of the invention
Deficiency in view of prior art exists the invention provides a kind of inductor in high frequency toroidal core, highly little that uses.
Invention is for realizing above-mentioned purpose; The technical scheme of taking is: a kind of inductor in high frequency; It is characterized in that: comprise toroidal core, printed circuit board (PCB), insulating trip, said printed circuit board (PCB) is a cuboid, on the face of cuboid, is provided with round tube hole; On the bottom surface at place, four angles of cuboid and two sides, coat one deck copper sheet, on the copper sheet of two sides of symmetry, be respectively equipped with semi-circular groove; Said toroidal core is bonded in the round tube hole on the printed circuit board (PCB), and four legs of toroidal core are separately positioned in four semi-circular groove and weld together with four copper sheets, and said insulating trip sticks on the toroidal core top.
The beneficial effect of the invention: used with coiling after magnet ring height (hollow out) printed circuit board (PCB) that equate, that be with round tube hole; Product height has been reduced to minimum (having reduced product height); Simultaneously, make printed circuit board (PCB), do not need die sinking tool (not producing the mould expense); Making provides the customed product of small lot to become possibility to the client, has reduced production cost.
