Title:
COMPOSITE WIRE AND PREPARATION METHOD THEREFOR, AND PREPARATION METHOD FOR POWER INDUCTOR
Document Type and Number:
WIPO Patent Application WO/2017/185345
Kind Code:
A1
Abstract:
Disclosed in the present invention are a composite wire and a preparation method therefor, and a preparation method for a power inductor, the composite wire comprising a metal core, an easily-passivated metal layer covering the surface of the metal core, and a self-adhesive resin layer covering the surface of the easily-passivated metal layer; the insulating layer of the composite wire is a metal passivation layer formed by oxidisation of the easily-passivated layer after sintering processing. The preparation method is used for manufacturing the composite wire. The preparation method for the power conductor is used for preparing a novel power inductor containing the composite wire. The composite wire of the present invention is resistant to high temperature and easy to wind; the easily-passivated metal layer cannot easily fall off during the winding process, thus ensuring that the insulating layer formed by passivation of same will have excellent weather resistance and pressure resistance.
