Abstract
An improved structure of inductance core and wire frame mainly provides a center post at the center portion of the core. A containing circumferential channel is also provided at the periphery of the center post to make the outer circumference of the containing circumferential channel form a surrounded circumferential side wall that has small area of indentation openings at the end corners only. A center hole is also provided at the center portion of the wire frame that accommodates the center post, and a bobbin for the winding of the coil is further provided at the outer circumference of the center hole. A salient lead-out seat is provided at the end corner of the wire frame, and brazing posts are also provided on the same side at the upper edge of each of the lead-out seat to connect to the drawing head of the coil. By the use of the center post of the core embedding into the center hole of the wire frame, as well as making use of the containing circumferential channel to contain the wire frame, each of the lead-out seat of the wire frame can stretch out through the openings of the core. The magnetic leakage can be lessened and the inductance efficiency can be improved by making u…
