Description
Technical field
The utility model belongs to inductor field, especially relates to a kind of annular inductor in high frequency.
Background technology
Inductor in high frequency in electronic equipment, under the prerequisite of guaranteed performance, requires size more and more less, and especially height, for mobile phone, this series products of panel computer, harsher to the requirement for height of inductor.Current inductor in high frequency structure, mostly is on " I-shaped " magnetic core and winds the line, and metal electrode is pasted in bottom.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 production difficulty is large, and qualification rate is low, therefore " I-shaped " magnetic core mostly is square, and height can not meet the demands.In addition, the heat accumulation of the bottom of power inductor is not considered in the design of existing most of inductor, but the area that adds cloth copper on large circuit board when user uses dispels the heat, and has caused the increase of cost to user side.
Summary of the invention
The problems such as the technical problems to be solved in the utility model is to provide a kind of annular inductor in high frequency, large to solve existing inductor dimensions, and cost is high, and radiating effect is poor.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of annular inductor in high frequency,
Comprise toroidal core, shielding magnetic cover, insulating trip, it is characterized in that: on described toroidal core, be arranged with inductance coil, between described inductance coil, leave space, the input and output joint of described inductance coil is provided with connector, the described shielding magnetic enclosure is located at described toroidal core outside, described toroidal core is connected by glue layer with described shielding magnetic cover, and described shielding magnetic cover is laterally disposed two blow vents, and described insulating trip is arranged at the top of described toroidal core.
Further, described shielding magnetic cover is cylindric.
Further, described blow vent is arranged at the edge of opening of described shielding magnetic cover.
The utility model has been used toroidal core, has reduced the height of inductor, makes inductor miniaturization; In shielding magnetic cover bottom, offer blow vent simultaneously, make the bottom of inductor form cross-ventilation, the heat that toroidal core produces when work is to inductor bottom, the blow vent of offering is not in the situation that affecting inductor characteristic, reduce the heat of inductor body, thereby reached the effect of cooling.Compare inductor similar with other, the utlity model has simple in structure, the feature such as size is less, and dependable performance is convenient for production, and weight and cost are all lower, and safety in utilization is reliable, and fitness is high, cooling successful.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of annular inductor in high frequency of the utility model, comprises toroidal core 1, shielding magnetic cover 2, insulating trip 7, on toroidal core 1, be arranged with inductance coil 3, leave space between inductance coil, the input and output joint of inductance coil 3 is provided with connector 6, shielding magnetic cover 2 is sheathed on toroidal core 1 outside, toroidal core 1 is connected by glue layer 4 with shielding magnetic cover 2, and shielding magnetic cover 2 is laterally disposed two blow vents 5, and insulating trip 7 is arranged at the top of toroidal core 1.
Blow vent 5 has been offered in the bottom of the shielding magnetic cover 2 at toroidal core 1 of annular inductor in high frequency, and blow vent 5 can be that through hole can be also edge groove, and offering two blow vents 5 can be so that cross-ventilation be formed on the bottom of inductor.The heat that toroidal core produces when work is to inductor bottom, and the blow vent of offering, in the situation that not affecting inductor characteristic, has reduced the heat of inductor body, thereby reaches the effect of cooling.
Preferably, toroidal core 1 is annular, has reduced the height of inductor, makes inductor miniaturization.
Preferably, shielding magnetic cover 2 is cylindrical, and blow vent 5 is arranged on the edge of opening of shielding magnetic cover 2, and convenient processing directly forms blow vent 5 between mounting panel and shielding magnetic cover 2, realizes cross-ventilation, realizes the effect of cooling.
The utlity model has simple in structure, the feature such as size is less, and dependable performance is convenient for production, and weight and cost are all lower, and safety in utilization is reliable, and fitness is high, cooling successful.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
