Production manner and production device null of lead/read frame and wire-wound tip/chip inductor for wire-wound inductor

摘要

PURPOSE: To enhance productivity to a large extent and to decrease the installation cost greatly by strikingly achieving the reduction in tact time for both a linking winding step and a remaining-wire removing step with the end processing of the wiring as the central point, and by making it possible to achieve the operation of a flyer winding machine sufficiently only with the operating mechanism along simply the Y axis in the traverse direction. ;CONSTITUTION: A magnetic core 12 is arranged on a pair of terminals. Both ends of a winding 13 applied around the magnetic core are connected to terminals. The magnetic core, the winding and the end parts of a pair of the terminals including the connecting parts of both ends are made to remain, and resin molding is performed in an inductor. In this inductor, the magnetic core is connected and fixed on a lead frame 11, to which both ends of the terminal are linked in the strip shape. One linking part is cut, respectively, and a comb-shaped linking body is formed. The connection of the winding and the ends is continuously performed in this manufacturing method of the inductor. In this method, the connecting body of the terminals and the magnetic core is formed in the slant pattern with respect to the sending direction (a) of the lead frame.;COPYRIGHT: (C)1994,JPO&Japio
