Abstract
The utility model relates to a high frequency inductor comprising an annular magnetic core, a printed circuit board and an insulating strip, wherein the printed circuit board is a rectangular body, a circular through hole is formed on the surface of the rectangular body, a layer of copper pieces is respectively wrapped on the bottom surface and the two side surfaces on four corners of the rectangular body, and semicircular grooves are respectively arranged on the copper pieces on the two symmetrical side surfaces; and the annular magnetic core is adhered in the circular through hole on the printed circuit board, four welding pins of the annular magnetic core are respectively arranged in the four semicircular grooves to be welded with the four copper pieces, and the insulating strip is adhered on the top part of the annular magnetic core. The high frequency inductor provided by the utility model has the beneficial effects that the printed circuit board having equal height as a coiled magnetic ring and provided with the circular through hole is applied to reduce the product height to minimum, and meanwhile, no mold is necessary for being opened for preparing the printed circuit board, so that small batch customized product provision for clients become possible and the production cost is reduced.
Description
Technical field
The utility model 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
In view of the deficiency that prior art exists, the utility model provides a kind of inductor in high frequency toroidal core, highly little that uses.
The utility model 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 utility model: 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.

Embodiment
Like Fig. 1,2,3, shown in 4; Inductor in high frequency; Comprise toroidal core 1, printed circuit board (PCB) 2, insulating trip 3, printed circuit board (PCB) 2 is a cuboid, on the face of cuboid, is provided with round tube hole 2-1; On the bottom surface at place, four angles of cuboid and two sides, coat one deck copper sheet 2-2, on the copper sheet 2-2 of two sides of symmetry, be respectively equipped with semi-circular groove 2-3; Toroidal core 1 after the coiling; Put into the round tube hole 2-1 (hollow out) on the printed circuit board (PCB) 2; In the gap between toroidal core 1 and printed circuit board (PCB) 2; Spacing is clicked and entered epoxy resin 4 and is bonded together the printed circuit board (PCB) 2 of toroidal core 1 with hollow out; Four legs (enamel-cover stitch) of toroidal core 1 are separately positioned among four semi-circular groove 2-3 and weld together with four copper sheet 2-2 (electrode), with epoxy resin 4 insulating trip 3 are sticked on toroidal core 1 top, form complete inductor in high frequency.Height such as toroidal core 1, printed circuit board (PCB) 2 highly are: 2.5mm.Insulating trip 3 is Nomex (Nomex (Nomex nylon)).
During use, four copper sheet 2-2 (electrode) of inductor in high frequency bottom are sticked on the base plate of metal electrode and get final product.
