Plug-in type integrally-formed inductor

Abstract

The invention discloses a plug-in type integrally-formed inductor, comprising a coil and a magnetic main body wrapping the outer side of the coil. A first welding pin and a second welding pin which extend downwards are arranged at the two ends of the coil respectively, a plurality of bosses are arranged at the bottom of the magnetic main body, and a plurality of heat dissipation grooves are formedbetween the bosses. According to the invention, the connector directly passes through the PCB in a plugging manner. The first welding pin and the second welding pin are firmly welded with the bottomsurface of the PCB, pseudo soldering is avoided, a high-requirement drop test can be passed, and the inductor is good in EMI resistance, large in saturation current, long in service life and small insize, and can be widely applied to automobile navigation, mobile phones, liquid crystal televisions, notebook computers, communication equipment and instruments.

Description

technical field [0001] The invention relates to the technical field of inductors, in particular to a plug-in integrated inductor. Background technique [0002] Inductors are components that can convert electrical energy into magnetic energy and store them. Inductors currently on the market mainly include assembled inductors and integrated inductors. The production cost of assembled inductors is low, but the inductance value tolerance is large, the products are fragile, the anti-EMI effect is poor, the labor-intensive production is labor-intensive, and the size is difficult to achieve miniaturization. One-piece inductors have good anti-EMI performance, large saturation current, automatic production, long service life, flattened and small volume. At present, most of the integrated inductors on the market are chip inductors, and the products are directly welded on the PCB surface. However, this chip inductor cannot pass the high-demand drop test because the electrode welding i...

The production cost of assembled inductors is low, but the inductance value tolerance is large, the product is fragile, the anti-EMI effect is poor, the labor-intensive production is difficult to achieve miniaturization

One-piece inductors have good anti-EMI performance, large saturation current, automatic production, long service life, flattened and small volume. At present, most of the integrated inductors on the market are chip inductors, and the products are directly welded on the PCB surface. However, this chip inductor cannot pass the high-demand drop test because the electrode welding is directly welded on the PCB board, and the contact area is small.
