Abstract
The utility model relates to a magnetic core for low-power devices, which is mainly used on low-power devices. At present, most of the magnetic cores used on low-power devices are of hollow cylindrical structures, the performance of the magnetic cores is poor, material consumption is high, and use is inconvenient. The magnetic core is characterized in that: the magnetic core comprises a vertical bar, a top bar, a bottom bar and a middle bar, the left and the right sides of the vertical bar are respectively provided with a left notch and a right notch, both of which are of trapezoidal structures, both the top bar and the bottom bar are of trapezoidal structures, one end of the vertical bar is fixed on one end of the top bar, the other end of the vertical bar is fixed on one end of the bottom bar, the middle bar is of a cylindrical structure, one end of the middle bar is fixed on the vertical bar, the top bar, the middle bar and the bottom bar are sequentially arranged on the front of the vertical bar, and are perpendicular to the vertical bar, and the surfaces of the top bar and the bottom bar, which face the middle bar, are of circular arc-shaped structures. The utility model has the advantages of reasonable structure design, low material consumption, convenient use and reliable performance.
Description
Technical field
The utility model relates to a kind of magnetic core, especially relates to a kind of magnetic core that is used for low-power device, is mainly used on the low-power device, as is used for high-frequency power transformer, choke and filter.
Background technology
Be used for the cylindrical structural that magnetic core on the low-power device mostly is hollow greatly at present, as be used for low-power device, as the structure that is used for the magnetic core of high-frequency power transformer, choke and filter is exactly columniform usually, this class magnetic core is poor-performing not only, and spillage of material is bigger, lead is wound into also comparatively inconvenience on the magnetic core, thereby greatly reduces the overall performance of magnetic core.
Summary of the invention
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and consumptive material is economized, and is easy to use, the magnetic core that is used for low-power device of dependable performance.
The technical scheme in the invention for solving the above technical problem is: these characteristics that are used for the magnetic core of low-power device are: this magnetic core is by vertical bar, the top bar, sill strip and central strip are formed, the left and right sides of described vertical bar has left breach and right breach, this left side breach and right breach are trapezium structure, described top bar and sill strip are trapezium structure, one end of described vertical bar is fixed on the end of top bar, the other end of this vertical bar is fixed on the end of sill strip, described central strip is a cylindrical structural, one end of this central strip is fixed on the vertical bar, described top bar, central strip and sill strip are sequentially arranged on the front of vertical bar, this top bar, central strip and sill strip are all perpendicular with vertical bar, and the one side towards central strip in described top bar and the sill strip is arc-shaped structure.
Magnetic core described in the utility model is an integral structure.
The length of vertical bar described in the utility model between 14-29mm, the length of described top bar between 2.9-6.6mm, the length of described sill strip and central strip all with the equal in length of top bar.
The utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, the left and right sides of vertical bar has the left breach and the right breach of trapezium structure, top bar and sill strip also are trapezium structure, outside lead can very easily be wound on the utility model, thereby has reduced workload, has improved the quality of product.
Dependable performance of the present utility model, production cost is low, and is very easy to use, is mainly used on the low-power device, as is used for high-frequency power transformer, choke and filter, can effectively promote the overall performance of high-frequency power transformer, choke and filter.
