Description

Combined inductor with reduced magnetic vibration and noise

The present invention is related to providing a combined inductive device that can significantly reduce magnetic vibration and noise effects when an inductance is energized to generate electromagnetic force.

The principle of inductance is to use different numbers of current-carrying metal frames added to the magnetic components, so that when the inductance passes current, electromagnetic force is generated and the current and voltage values are changed, thereby outputting various DC power supplies that require current and voltage values.

The so-called combined inductor is mainly an inductor composed of one or more magnetic iron core components and at least one metal conductive sheet. Metal frame including input and output.

The combination of the combined inductor is to put the metal frame into the accommodation space reserved on the inner edge of the magnetic iron core, and add adhesive bonding to complete the combined electrical inductor. When the inductor is energized, the magnetic iron core and the load The current metal frame generates electromagnetic force after electrical interaction, so as to achieve the expected inductance performance.

As shown in Figures 1 and 2, the conventional metal frame (1) sandwiched inside a conventional block inductor has a neat straight line on its bent horizontal or vertical surface, and is connected to the adjacent magnetic iron core when the current passes through it. When the components interact with each other and generate electromagnetic force, an obvious magnetic resonance effect will be produced, which will lead to serious magnetic vibration and noise, so that the finished product has defects of different severity.

In view of the above-mentioned lack of traditional combined inductors, we developed and created the product with the target of "combined inductors with reduced magnetic vibration and noise".

The present invention provides a combined inductor with reduced magnetic vibration and noise, which is characterized in that the metal frame in the combined inductor is provided with a deflection at an oblique angle on its horizontal section or upright section.

The above-mentioned upright sections of the metal frame of the inductor are symmetrical on both sides, and the deflections set on them can be set as deflections in the same direction or opposite directions.

The method of setting the deflection on the metal frame in this creation can be implemented on a single main metal frame in the inductor, or in a plurality of main metal frames and sub-metal frames, one or all of the deflection structures can be implemented.

According to the above, the technical content of the object of this creation can obviously reduce the magnetic resonance and noise effects commonly caused when the inductor is energized and operated.

Please refer to Fig. 2-5. The present invention has a combined inductor that reduces magnetic vibration and noise. In addition to the conventional set of magnetic iron cores (2, 3), a main metal frame (4) and a secondary metal frame ( 5) In addition, the improvement is characterized in that the horizontal section (41) and the symmetrical vertical section (42) of the main metal frame (4) or the auxiliary metal frame (5) are provided with an angled deflection (411). , 421), when the inductor is energized and operated, the magnetic resonance and noise effects are reduced accordingly.

The upright sections (42) of the main metal frame (4) or the secondary metal frame (5) of the above-mentioned inductor are symmetrical on both sides, and the deflections (421) established thereon can be set as deflections in the same direction or opposite directions.

The main metal frame (4) or the sub-metal frame (5) in this creation, the way of setting deflections (411, 421) on it, can be implemented on a single main metal frame (4) in the inductor, or it can be implemented on a plurality of main metal frames. In (4) and the sub-metal frame (5), one or more of the deflection structures are selected to implement the deflection structure, so as to achieve the expected reduction of magnetic resonance and noise effects commonly caused when the inductor is energized and operated.
