Abstract
The utility model relates to a low-temperature-rise and high-power inductor, and belongs to the field of high-frequency power source inductors. The low-temperature-rise and high-power inductor is provided with a skeleton, and pins are installed on the skeleton. The low-temperature-rise and high-power inductor is characterized in that a winding part of the skeleton is of a cylindrical structure, an annular boss is machined in the outer side wall of the middle of the winding part of the skeleton, a wire duct is axially machined in the boss, a varnished wire is wound around the portion, on one side of the annular boss, of the skeleton, penetrates through the wire duct in the boss and is wound around the portion, on the other side of the annular boss, of the skeleton, the two ends of the varnished wire are welded to the skeleton, the varnished wire wound around the skeleton is packaged though insulating rubber tape, and center posts of two E-shaped magnetic cores are inserted from the two sides of the skeleton. The varnished wire is positioned through the boss on the skeleton, and the powerful magnetic force wire on the boss will not perform magnetic force cutting and heating on copper wires, so that the temperature rise of the inductor is effectively reduced, and the overall efficiency of a switch power source is improved.
Description
Technical field
The utility model relates to high frequency electric source inductor field, at length says it is a kind of high-frequency high-power PFC inducer using for high frequency switch power inside.
Background technology
Well-known: along with the development of Switching Power Supply, power requirement constantly increases, the storage power of the PFC inducer in Switching Power Supply is also increasing, the air gap that requires like this magnetic material to need also strengthens, the high-frequency magnetic leakage producing will bombard the enamelled wire on side, produce high temperature, consumed power, lowers efficiency.
Summary of the invention
The purpose of this utility model is just to overcome the deficiencies in the prior art, and a kind of low-temperature-rise large power, electrically sensor is provided, and reduces temperature rise, improves power efficiency.
The utility model adopts following technical solution: a kind of low-temperature-rise large power, electrically sensor, be provided with skeleton, be provided with skeleton, pin is installed on skeleton, it is characterized in that, the coiling position of skeleton is cylinder-like structure, on the lateral wall in the centre position, coiling position of skeleton, be processed with annular boss, boss be axially processed with wire casing, on the skeleton of annular boss one side, be wound with enamelled wire, enamelled wire is wound around on the skeleton of annular boss opposite side through the wire casing on boss, the two ends of enamelled wire are welded on skeleton, the enamelled wire being wound around on skeleton is encapsulated by insulating tape, the center pillar of two " E " font magnetic cores inserts from skeleton both sides.
The utility model also can be achieved by the following measures: the gap position between two " E " font magnetic core center pillars is just positioned at boss middle part.Two " E " font magnetic cores are fastened together by insulating tape.
The beneficial effects of the utility model are, by skeleton boss, enamelled wire are located, and the strong magnetic line of force at boss position can not carried out magnetic force cutting heating to copper cash, effectively reduces the temperature rise of inductor, improves the whole efficiency of Switching Power Supply.
