The invention provides a closed-loop magnetic core structure which comprises a magnetic core body, the magnetic core body comprises a bottom plate and a top plate, the left end and the right end of the bottom plate are connected with the left end and the right end of the top plate through side walls respectively, and the two side walls are sequentially connected with the bottom plate and the top plate to form a closed loop; a middle column is further arranged between the bottom plate and the top plate, the two ends of the middle column are connected with the side walls respectively, and the middle column divides the space between the bottom plate and the top plate into two independent magnetic cavities; the top plate, the bottom plate, the middle column and the side walls are integrally formed. According to the closed-loop magnetic core structure, on the premise that a magnetic circuit structure is not changed, a gap in the middle of a magnetic core in the prior art is moved to the two ends of a coil, the process of grinding a low middle column is omitted, manpower and equipment cost is reduced, environmental pollution is avoided, meanwhile, the magnetic leakage phenomenon is avoided, and the electromagnetic conversion rate is improved.
Description
technical field [0001] The invention relates to the electromagnetic field, in particular to a closed-loop magnetic core structure. Background technique [0002] figure 1 It is a common split magnetic core structure in the center of the prior art. It is composed of two symmetrical E-shaped bodies 1', and a coil is arranged in the middle. At present, in the actual production process of soft ferrite cores used in inductors, gap processing is required. The way to form the gap is generally to use a grinding wheel to grind the center column 2' in the middle of the E-shaped body of the magnetic core to shorten its size when it is released from the mold, while the size of the legs on both sides of the magnetic core body remains unchanged, thus forming in the middle. The gap used to adjust the inductance of the transformer. [0003] The magnetic core in the prior art usually includes two magnetic core units, and the two magnetic core units are combined to form a pair of magnetic c...
