A Welded Firm Flat Wire Vertical Wound Inductor and Its Packaging Method

Abstract

The invention provides a vertically wound inductor with welded firm flat wire and its packaging method, which comprises an inductor housing, the inner wall of the inductor housing is fixedly connected with a shielding layer, and the upper end surface of the inductor housing and the shielding layer An injection port and a vent hole are opened through, and an epoxy plate is fixedly connected to the lower end surface of the inductor shell and the shielding layer, and a magnetic core is fixedly connected to the upper end surface of the epoxy plate, and the magnetic core is located on the shielding layer. Inside the layer, the core includes a core body, a first extension leg, a second extension leg, a first communication slot, a fixing slot, a limit block, a second communication slot and a conductive insert, and the first extension leg and the second extension foot are fixedly connected to the end of the magnetic core body, the fixed groove is opened on the outer surface of the magnetic core body, and the limit block is fixedly connected to the inner wall of the fixed groove. The present invention uses a sheet guide plate instead of a flat wire process The difficulty of coil winding is reduced while the thermal stability of the inductor is improved, and the structure of the inductor is more excellent.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a welded solid flat wire vertical wound inductor and a packaging method thereof. Background technique [0002] Inductor is a component that can convert electrical energy into magnetic energy and store it. Inductors are similar in construction to transformers, but with only one winding. Inductors have a certain inductance, which only resists changes in current. If the inductor is in a state where there is no current flowing, it will try to block the current flow through it when the circuit is on; if the inductor is in a state where current is passing, it will try to maintain the current when the circuit is off. Inductors are also called chokes, reactors, and dynamic reactors. [0003] Inductors can be made of a coiled core of electrically conductive material, typically copper wire, or the core can be removed or replaced with a ferromagnetic material. A core material with a ...

Problems solved by technology

[0004] Existing vertically wound inductors are usually wound with enameled wire, which is prone to skin effect when passing high-frequency current, and then wound with flat wire, but the winding process of flat wire is more difficult and the process is more complicated, and the existing vertically wound inductor Inductors are inconvenient to solder. When soldering, there are generally two soldering methods: pin type and patch type. Existing inductors can only support a single soldering method. Existing inductors leave air inside after packaging. It is easy to aggravate the aging of the coil and affect the service life of the inductor
