摘要： PROBLEM TO BE SOLVED: To provide a low-cost ignition coil for internal-combustion engines which can supply high electrical energy to a spark plug required for spark discharge, which can be attached into a plug tube, and which can be miniaturized. SOLUTION: The ignition coil for an internal combustion-engine primarily comprises a transformer 5, a control circuit 7 and a joint 6. The transformer 5 comprises an open magnetic path structure comprising an iron core 502, magnets 504, 506, a secondary spool 510, a secondary coil 512, a primary spool 514, and a primary coil 516. Primary energy generated in the primary coil 516 can be increased, without increasing an outer diameter A of a case 100, by setting the cross-sectional area SC of the magnetic core 502 to 39 to 54 mm 2 , a ratio between the cross-sectional area SM of the magnets 504 and 506 and that SC of the iron core 502 is set to 0.7 to 1.4, and a ratio between the axial length Lc of the magnetic core 502 and the winding width L of the primary and secondary coil is set to 0.9 to 1.2, and the spool width L to 50 to 90 mm.

摘要： PROBLEM TO BE SOLVED: To suppress the generation of cracks (flange leakage) in a stick coil due to thermal stress. SOLUTION: The dimension L of a part of a projection 121b which is parallel to the axial direction of a primary spool 121 is set larger than the dimension T of a part parallel to a direction perpendicular to the axial direction of the primary spool 121. Due to this dimensional relationship, the front projected area of the projection 121b viewed from the direction of a resin flow becomes small, hardly causing the disordered flow of the resin and the generation of entrainment voids and welding when the resin is caused to flow between parts corresponding to the projections 121b during forming. Consequently, a decline in the mechanical strength of a base of the projection 121b can be prevented, resulting in preventing the generation of cracks in the base of the projection (flange) 121b due to thermal stress.

摘要翻译：要解决的问题：抑制由于热应力引起的棒状线圈中的裂纹（凸缘泄漏）的产生。
解决方案：突起121b的与初级线轴121的轴向平行的部分的尺寸L被设定为大于与垂直于主线轴的轴向方向的方向平行的部分的尺寸T. 由于这种尺寸关系，从树脂流动方向看的突起121b的前投影面积变小，当树脂流动时，几乎不引起树脂的无序流动和产生夹带空隙和焊接在成形期间对应于突起121b的部分。因此，可以防止突起121b的基部的机械强度的下降，从而防止由于热应力而在突起（凸缘）121b的基部中产生裂纹。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic coil which improves the insulation quality and production efficiency, and reduces the electromagnetic coil in size. SOLUTION: A traverse shaft section 609 shifts in response to the rotation of a bobbin rotating section 604 at a predetermined winding pitch P1, for example, equivalent to two to ten times of the diameter of a wire rod 520. With this shift movement of the traverse shaft section 609, the wire rod 520 extracted from a winding nozzle section 610 shifting together with the traverse shaft section 609 is wound spirally along a slant surface 530 formed by a primary winding section 541 at the winding pitch P1 equivalent to two to ten times of the diameter of the wire rod. As a result, an advancing-side wire rod 520a and a reversing-side wire rod 520b cross over each other at opposing inclinations. Hence, it becomes possible to prevent the reversing-side wire rod 520b, when wound on the advancing-side wire rod 520a, from pulling and dislocating the advancing-side wire rod 520a from its regular winding position, thereby eliminating undesirable winding collapse.

摘要翻译：要解决的问题：提供提高绝缘品质和生产效率的电磁线圈，并减小电磁线圈的尺寸。解决方案：横动轴部分609响应筒管旋转部分604的旋转而以预定的卷绕间距P1移动，例如等于线材520的直径的2至10倍。随着这种移动横动轴部分609的移动，从卷绕喷嘴部分610抽出的线材520与横动轴部分609一起移动，沿着由初级绕组部分541形成的倾斜表面530以相当于两个的卷绕间距P1卷绕到线的直径的十倍。结果，前进侧线520a和反转侧线520b在相对的倾斜处彼此交叉。因此，可以防止反转侧线520b在行进侧线520a上卷绕时使前方侧线520a脱离其规定绕线位置，从而消除不希望的卷绕塌陷。版权所有（C）2007，JPO＆INPIT
