Description
Technical field
The present invention relates to inductance element manufacture and technical field of structures, particularly relate to a kind of inductance element.
Background technology
Inductor is developed so far the application of existing suitable broad range, comprises communication system, signal processing system, filter, resonant circuit (tank circuit) etc., all needs inductor to reach the object of circuit.Along with lower bound time stamp, electronic system reduces gradually, makes electronic component also necessary scaled, therefore, when not getting rid of inductor in circuit design, engineers is just devoted to the size reducing inductor, increases compressive resistance and the generation probability of electric arc of preventing.
Inductance element is the passive device in electronic circuit, and basic building block comprises magnetic core and coil.In order to adapt to different electronic circuits, just design multi-form inductance element, multi-form inductance element has different inductance attributes, just has different characteristics than if any the inductance element in gap and gapless inductance element.Compared to the inductance element having gap, gapless inductance element ferromagnetic very close to each other, inductance element can be made to have higher value of inductance and small electric stream, and have the inductance element in gap, gap on this is ferromagnetic can prevent when electric current flows through inductance element, causes inductance element enter magnetic saturation state and cannot use.
Please refer to Fig. 1, is the three-dimensional structure diagram of existing inductance element of demonstrating.Existing inductance element comprises an a wound portion P11 and two flange portion P12, each flange portion P12 has again four enamelled wire holding part P121, so, in existing inductance element processing procedure, be that four enamelled wire P2 are first wound in this wound portion P11, then the two ends of each enamelled wire P2 are arranged on these enamelled wire holding parts P121 respectively.
