Description

Technical Field

[0001] The present application relates to the field of inductor technology, and in particular to an integrated flat wire anti-vibration inductor. Background Art

[0002] One-piece molded inductors generally include a seat body and a winding body. The seat body is die-casted by burying the winding body inside metal magnetic powder, and the SMD pins are the lead-out pins of the winding body directly formed on the surface of the seat body.

[0003] Traditional integrated inductors use round wires to lead out soldered sheets as terminal patches. The soldered ends of the round wires and the sheets are prone to falling off and opening, especially when affected by some vibrations. Therefore, the overall seismic performance of the inductor is relatively weak, and its usage scenarios are also subject to corresponding restrictions. Utility Model Content

[0006] In the above implementation process, this solution uses flat wires as patch terminals, and the flat wire body is led out as patch points. There is no need for soldering sheets as terminal patches. In addition, the flat wire has a large area and can absorb a large amount of tin, is not easy to fall off during vibration movement, and has a more solid and safer anti-seismic effect, thereby effectively improving product quality, making it suitable for more demanding usage scenarios and increasing its scope of application.

[0007] Preferably, the wire body and the magnetic core body are hot pressed;

[0008] In the above implementation process, the traditional round wire is formed by cold pressing, and this solution adopts flat wire hot pressing powder die casting, which has low molding pressure, high product safety factor and excellent electrical characteristics.

[0009] Preferably, a groove is provided on the magnetic core body along the winding direction of the wire body, and the wire body is embedded in the groove;

[0010] In the above implementation process, the groove can limit the wire body, thereby further improving the anti-vibration performance of the inductor.

[0011] Preferably, it further comprises an outer shell in the form of a rectangular parallelepiped, wherein the outer shell is provided with a receiving groove suitable for receiving the magnetic core body;

[0012] When the magnetic core body is accommodated in the outer shell, the first side surface of the magnetic core body is exposed outside the outer shell.

[0013] Preferably, the wire body at the corner of the magnetic core body is in an arc-shaped chamfered shape.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows: the present solution uses a flat wire as a patch terminal, and the flat wire body is led out as a patch point, and there is no need for welding sheet as a terminal patch. In addition, the flat wire has a large area and can absorb a large amount of tin, is not easy to fall off during vibration movement, and has a more solid and safer anti-seismic effect, thereby effectively improving product quality, making it suitable for more demanding usage scenarios, and improving its scope of application.

The base system buries the winding body in metal magnetic powder by die-casting, and the SMD pins are the lead pins of the winding body directly formed on the surface of the base body. The traditional one-piece inductor uses round wire to lead out the welding sheet as the terminal patch. The welding end of the round wire and the sheet is easy to fall off and open circuit, especially when affected by some vibrations.

[0031] In the above scheme, the traditional round wire is formed by cold pressing, while this scheme adopts flat wire hot pressing powder die casting, which has low molding pressure, high product safety factor and excellent electrical characteristics.
