    摘要： Disclosed is a transformer bobbin with hipot-protect structure. The bobbin is integrally formed from plastic material through injection molding and includes a central shaft portion and an outer frame portion at two ends of the central shaft portion. When the bobbin is formed during molding, the outer frame portion is extended from one or two lateral outer ends thereof for a length and therefore forms one or two extended portions on the bobbin. Upright rib or ribs may be additionally provided on top surface of the extended portion. The extended portion provide increased creepage distance between pins connected to outer end surfaces of the bobbin and the core of the transformer to effectively prevent hipot from transiting from pins at one end to pins at the other end by crossing over the core directly.

    摘要： A hipot barrier structure for a transformer for preventing instantaneous hipot from transiting from pins at high-tension side to pins at low-tension side directly via a conductive core of the transformer, so that damages to the whole circuitry can be avoided to comply with required safety code. The barrier structure includes a barrier member made of insulating material and having a generally C-shaped cross-section for fitly covering the high-tension side of the core in a tight fit relation and forming an outer layer of the core at the high-tension side. The barrier member increases a creepage distance between the pins and the conductive core and therefore effectively prevents a hipot from directly crossing over the core.

    摘要： A coil rack for transformer including a coil winding seat around which an inner and an outer coil windings are sequentially provided. Axially extended through holes are formed on a bottom of the coil winding seat at positions spaced below the inner coil winding. Stoppers are provided to separately locate radially outside the through holes. Each of the stoppers is provided at a bottom surface with a radially extended open channel of which one end leads to the through hole and another end to an outer end of the coil rack. Free ends of the inner coil winding are separately guided downward via the axially extended through holes and then outward via the radially extended open channels on bottom surface of the stoppers to avoid contact with the outer coil winding and any possible short circuit.

    摘要： A miniature transformer is provided at each end surface of a bobbin thereof with two spaced principal pins and two spaced dummy pins located between the two spaced principal pins. The dummy pin each is an integral extension from a rear end of an extended rear section of one adjacent principal pin embedded in the bobbin. The extended rear section extends obliquely forward toward a central area of the end surface of the bobbin and then turns straight forward to project from the end surface to form the dummy pin. The dummy pin each is provided at an inner side with a curved notch for a lead from windings on the miniature transformer to wind around there without further reducing a small distance between two adjacent dummy pins. Since the dummy pins are located between and shorter than the principal pins, they are protected by the principal pins without being easily touched or pulled to cause broken leads that would result in high bad yield in the production of the miniature transformer.

    摘要翻译： 在其线轴的每个端面处设置有两个间隔开的主销和位于两个间隔的主销之间的两个分开的虚拟销的微型变压器。 虚拟销各自是从嵌入在线轴中的相邻主销的延伸后部的后端的整体延伸。 延伸的后部部分向着筒管端面的中心区域倾斜地向前延伸，然后直接向前转动以从端面突出以形成虚拟销。 虚拟针各自在内侧设置有用于来自微型变压器上的绕组的引线的弯曲凹口，以在其周围缠绕，而不会进一步减小两个相邻虚拟引脚之间的小距离。 由于虚拟引脚位于主引脚之间并且短于主引脚，所以它们被主引脚保护，而不会容易地被触发或拉动，导致断线，导致微型变压器的生产中的高产率。
