Abstract
The utility model relates to a magnetic core, particularly to a magnetic core for small power devices. The magnetic core is mainly used in high frequency power transformers, chokes, electronic transformers and electronic ballasts. The magnetic cores used on small power devices at present basically adopt hollow cylindrical structures, and have the defects of poor properties, inconvenient use and poor integral properties. The utility model is characterized in that the magnetic core consists of a vertical strip, a top strip, a bottom strip and a middle strip; a trapezoid opening is arranged at the right side of the vertical strip, both the top strip and the bottom strip are in cuboid structures, one end of the vertical strip is fixed on one end of the top strip, the other end of the vertical strip is fixed on one end of the bottom strip, one end of the middle strip is fixed on the vertical strip, the top strip, the bottom strip and the middle strip are all arranged on the front surface of the vertical strip, and the top strip, the bottom strip and the middle strip are all perpendicular with the vertical strip. The utility model has the advantages of reasonable structure design, material saving, 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, electronic transformer and electric ballast.
Background technology
Be used for the cylindrical structural that magnetic core on the low-power device mostly is hollow greatly at present, as the structure that is used for the magnetic core of high-frequency power transformer, choke, electronic transformer and electric ballast 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 right side of described vertical bar has a trapeze cut, described top bar and sill strip are rectangular 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, one end of described central strip is fixed on the vertical bar, described top bar, sill strip and central strip all are positioned on the front of vertical bar, this top bar, sill strip and central strip are all perpendicular with vertical bar.
Magnetic core described in the utility model is an integral structure.
The length of vertical bar described in the utility model between 14-21mm, the length of described top bar between 7-18mm, 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: top bar and sill strip are rectangular structure, have a trapeze cut on the right side of vertical bar, make that use is very convenient, outside lead can very easily be wound on the utility model, the utility model is mainly used on the low-power device, as be used for high-frequency power transformer, choke, electronic transformer and electric ballast, can effectively promote the overall performance of high-frequency power transformer, choke, electronic transformer and electric ballast.
Of the present utility model simple in structure, reasonable in design, dependable performance, production cost is low, and is easy to use, thereby reduced workload, improved the quality of product.
