Abstract
A method for manufacturing coil holders aims to improve the disadvantages of complicated fabrication processes and undesirable production efficiency of the conventional techniques. The method includes: providing a bobbin and a conducting wire and winding the conducting wire on the bobbin, encasing the bobbin wound with the conducting wire with a molding material and reserving a through hole in the molding material corresponding to the bobbin to form a coil rack, and inserting a magnetic core into the through hole to hold on the coil rack to become a finished product of a coil holder. The present invention can finish fabrication of the coil holder through only one injection molding process. It greatly simplifies fabrication process and can reduce cost and increase production yield.
