Description

I-shaped inductor

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the electronic component field, concretely relates to I-shaped inductance.

[ background of the invention ]

The inductor is an element capable of converting electric energy into magnetic energy for storage, the structure of the inductor is similar to that of a transformer, but only one winding is provided, and the inductor has certain inductance and only blocks the change of current. When the circuit is in a state of no current passing, the circuit tries to block the current passing, and when the circuit is in a state of current passing, the circuit is switched off and tries to keep the current unchanged; the inductor has the characteristic of preventing alternating current from passing through and allowing direct current to pass through smoothly.

The shielding outer cover in the inductor is a part for avoiding external interference and simultaneously improving magnetic flux, but the existing shielding outer cover has large space gap due to the connection structure with the magnetic core, so that the assembly is relatively inconvenient on one hand, and space waste and material waste are caused in a relatively small internal row plate on the other hand.

[ Utility model ] content

In order to solve the existing problem that exists among the background art, the utility model provides a I-shaped inductance.

The utility model adopts the following technical proposal:

the utility model provides a I-shaped inductance, includes shield cover, I-shaped magnetic core, enameled wire and copper sheet, the cavity that leads to in the inside middle formation of shield cover, the enameled wire around establishing the multilayer and forming the coil cladding in I-shaped magnetic core outside just adorn in the cavity, two concave positions that are used for the installation are seted up to shield cover one end surface, the enameled wire both ends are connected respectively the copper sheet.

Further, the I-shaped magnetic core is a ferrite powder core.

Further, the enameled wire is wound in a close winding or interval winding mode.

Furthermore, a vertical pin is formed at one end of the bottom surface of the copper sheet and is positioned outside the shielding case, and the bottom surface of the copper sheet is bonded on the concave position through glue.

Further, the pins are located on the diagonal line of the end face of the shielding case.

Further, the I-shaped magnetic core is bonded in the cavity of the shielding case through glue.

Furthermore, two ends of the enameled wire are welded and connected to the copper sheet.

The utility model has the advantages as follows:

the utility model discloses dwindle the distance between shield cover and the magnetic core, strengthened corresponding magnetic flux and promoted the inductance value, also satisfied arranging of littleer internal circuit module simultaneously, saved space and material, the assembly is simple and convenient.
