Problems solved by technology

[0004] However, the aforementioned conventional one-piece inductor still has many shortcomings in its own structure and performance.
First of all, when the coil and the electrode piece are connected by welding, the free end of the coil and the electrode piece are simply overlapped together for welding operation, and there is no corresponding fixed structure, which makes the connection strength between the coil and the electrode piece weak and easy Looseness will affect the normal connection, and even cause the product to be scrapped
Secondly, the welding

Abstract

The invention discloses an integrally formed inductor and a manufacture process thereof, comprising a coil, two electrode pins and a magnetic solid body formed by press powder. The coil is embedded in the magnetic solid body; first end parts of the two electrode pins are embedded in the magnetic solid body with electric clearances and are electrically connected with two pins of the coil; second end parts of the two electrode pins are bent and tightly attached to the surface of the magnetic solid body; the first end part of each electrode pin is provided with two vertical clamping pieces which are integrally bent and formed; and the pins of the coil are clamped in the two vertical clamping pieces and are welded and electrically connected. By adopting the structure, the connection strength between the coil and the electrode pins is enhanced, the connection reliability between the coil and the electrode pins is ensured, thereby avoiding the quality hidden trouble and finally greatly improving the quality of products. In addition, through reasonably arranging the manufacture process of the inductor and simplifying the manufacture flow, the invention ensures that the manufacture of the inductor can be finished automatically, simply and fast, and has the remarkable characteristics of high efficiency and high quality.

Description

technical field [0001] The invention relates to the field of inductors for electronic devices, in particular to an integrated inductor with better quality, more beautiful appearance, and higher manufacturing efficiency and its manufacturing process. Background technique [0002] Inductors, also known as inductance coils, are one of the basic components of electronic circuits. In an AC circuit, the inductance coil has the ability to hinder the passage of AC, but it has no effect on DC (except for the DC resistance of the coil itself), so the inductance coil plays the role of blocking, step-down, cross-connection coupling and load etc. When the inductance and capacitance cooperate, it can be used for tuning, filtering, frequency selection, decoupling, etc. [0003] In terms of the development process of inductors, the early inductors were mainly wire-wound inductors. The structure of wire-wound inductors is to wind the enameled wire around the outside of the magnetic conduct...
