Problems solved by technology

[0003] The inductance of coils made of metal sheets has been used in many applications, but the inductance of ordinary metal sheets as coils cannot meet the electrical requirements because of the limitation of only a single turn and the low inductance, or in order to achieve electrical requirements. Requirements to increase the volume to increase the inductance
[0004] Moreover, due to the simple structure of the traditional inductance, it is impossible to achieve low power (if the inductance is high at this time, the ripple current will be small and the efficiency is high) and high power (inductance) when the product is applied in the circuit by controlling different gaps. Stable, if the reliability is high in the case of overload) performance in different operating environments

Embodiment Construction

[0033] refer to figure 1 As shown, the assembled laminated inductor device of the present invention includes an approximately 8-shaped metal sheet coil 1 formed by stamping, three iron core bodies 2, 3, 4 and two sheet bodies 5, upper, middle, and lower. 6.

[0034] The above-mentioned approximately 8-shaped metal sheet coil 1 is generally made of copper sheet by stamping, and of course it does not exclude the use of other types of electrical conductor materials. The ends of the two vertical surfaces 12 are staggered and then bent inwardly to form a lower plane 13, and the ends of the lower plane 13 are respectively bent downwards to form upright electrical conductive pins 14 and bent legs 15 at the ends.

[0035] The stamping structure of the approximate 8-shaped sheet metal coil 1 forms a multi-layered coil mechanism with an approximate 8-shaped shape and an upper-layer accommodating space 16 and a lower-layer accommodating space 17 .

[0036] The upper iron core body 2, t...

Abstract

The invention provides an assembled stacked inductor device, and particularly relates to a power-type inductor. The assembled stacked inductor device comprises an approximately 8-shaped sheet metal coil formed through stamping, three iron core bodies and two sheet bodies; after the iron core bodies are assembled in the upper, middle and lower spaces of the approximately 8-shaped sheet metal coil, the assembled stacked inductor device of two or three inductance coils is formed on the periphery of the iron core bodies. The inductor device of the structure can realize promotion of the inductance value and adjusts the size of the inductance value by means of the control for the gaps of the iron core bodies, so that flexible combination of various inductance characteristics is achieved.

Description

technical field [0001] The invention relates to an assembled laminated inductance device, in particular to a power type inductance device with low voltage and high current. Background technique [0002] In recent years, for power supply products or power modules in circuit systems, the pursuit of high-power inductors has always been where design engineers and component manufacturers spend the most effort, especially in low-voltage and high-current circuit applications, such as DC To the DC power supply module (DC-DCModule) and the circuit and other components of the voltage rectification module (VRMs) in the server. [0003] The inductance of coils made of metal sheets has been used in many applications, but the inductance of ordinary metal sheets as coils cannot meet the electrical requirements because of the limitation of only a single turn and the low inductance, or in order to achieve electrical requirements. Requirements to increase the volume to increase the inductanc...
