线圈装置;COIL DEVICE

摘要

本发明提供一种可减少组装步骤之工时的线圈装置。;本发明之线圈装置系具有：在筒部的两端分别突出设置有凸缘部而成之合成树脂制的线圈架1；贯通该线圈架1之内部的磁性铁芯30；及卷装在该线圈架1之筒部的周围之线圈5。线圈架1系朝前述筒部的轴方向分割为复数个线圈架区段，互相邻接之2个线圈架区段彼此系藉由卡止构造而互相连结。在该等复数个线圈架区段之中之位于两端的2个线圈架区段突出设置有前述凸缘部，在前述凸缘部系以朝向另一方的凸缘部之方式突出设置有突片14、15，前述突片14、15系在从前述线圈5拉出之2条引线51、52的基端部中分别覆盖一方的基端部而阻止前述基端部从线圈5离开。;The coil device of the present invention comprises: a bobbin 1 made of synthetic resin and provided with flanges on both ends of a cylinder; a magnet core 30 penetrating the interior of the bobbin 1; and a coil 5 rolled up around the cylinder of the bobbin 1. The bobbin 1 is divided into a plurality of bobbin sections in the axis direction of the cylinder, and two mutually adjacent bobbin sections are connected to each other by a engaging structure. In the plurality of bobbin sections, the flanges are provided in a projection fashion at the two bobbin section on both ends. A plurality of tabs 14 and 15 are provided in the flange to project toward the other flange, wherein the tabs 14 and 15 cover one base end of two leads 51 and 52 pulled out from the coil 5 respectively, so as to prevent the base end from going off the coil 5.
