摘要： An electromagnetic contactor includes an iron core members formed of a first core bent in a U-shape, and a second L-shaped core contacting the first core. A coil is wound around a spool disposed on an upper arm of the first core and the second core to form a main leg while a lower arm of the first core constitutes a yoke. Thus, the iron core members can be processed by a press machine operating at a normal cutting speed, and welding and polishing operations can be eliminated to thereby reduce the number of processing steps required.

摘要： A terminal device for an electric equipment is formed of a frame having a terminal housing, a fixed terminal situated in the terminal housing, and a terminal screw having a male screw to be coupled to a tapped hole of the fixed terminal and an inverse L-shaped washer. The inverse L-shaped washer includes one side for rotatably holding the male screw and a guide plate section bent relative to the one side. A guide groove is formed in the terminal housing for receiving the guide plate section therein to vertically guide the same. Also, the terminal device includes an engagement section having a first engaging part formed on the guide plate section and a second engaging part formed at a portion facing the guide groove and engaging the first engaging part to temporarily hold the guide plate section in the guide groove. Thus, the terminal screw can be held directly above the tapped hole, which enables the male screw to be stably and easily inserted into the tapped hole, and which facilitates simple rewiring.
摘要翻译： 电气设备的终端装置由具有端子壳体，位于端子壳体中的固定端子和具有连接到固定端子的螺纹孔的外螺纹的端子螺钉的框架形成， 形垫圈。 反向L形垫圈包括用于可旋转地保持阳螺纹的一侧和相对于一侧弯曲的引导板部分。 引导槽形成在端子壳体中，用于在其中容纳引导板部分，以垂直地引导引导槽。 此外，终端装置还具备：接合部，其具有形成于导板部的第一卡合部和与导向槽相对的部分形成的第二卡合部，与第一卡合部卡合，将引导板部暂时保持在引导槽 。 因此，端子螺钉可以直接保持在螺纹孔的正上方，这使得外螺纹能够稳定且容易地插入到螺纹孔中，并且便于简单的重新布线。

摘要： A terminal device for connecting contacts to terminal strips fixed on respective terminal housing portions of an electrical apparatus, each of the terminal strips having a screw hole, the terminal housing portions being separated by insulating walls from one another. The terminal device includes a plurality of terminal screws, each including a male screw, and an L-shaped washer supported loosely and rotatably on the male screw and having a guide plate portion extending opposite to the terminal strip; a terminal cover covering the terminal housing portions and having round holes for handling the respective terminal screws; a guiding portion each including a vertical trench formed on a side plate of the terminal cover and having an opening facing the round hole, for guiding the guide plate portion slidably to and from the terminal strip along the vertical trench; a plurality of coupling claws, each disposed between the round hole and the male screw, for holding the terminal screw such that a tip of the male screw is spaced from the terminal strip for a certain distance; and a swinging mechanism for releasing the guide plate portions from the guiding portions, respectively, when the tips of the male screws are coupled to the respective terminal strips, to allow the washers to swing.
摘要翻译： 一种用于将触点连接到固定在电气设备的相应端子壳体部分上的端子条的端子装置，每个端子条具有螺纹孔，所述端子壳体部分被绝缘壁彼此分离。 端子装置包括多个端子螺钉，每个端子螺钉均包括一个外螺纹和一个L形垫圈，其松动地和可旋转地支撑在外螺纹上并具有与端子条相对延伸的引导板部分; 覆盖端子壳体部分并具有用于处理各个端子螺钉的圆孔的端子盖; 引导部分，每个引导部分包括形成在终端盖的侧板上的垂直沟槽，并且具有面向圆孔的开口，用于沿着垂直沟槽可滑动地引导引导板部分和从端子条引导; 多个联接爪，每个设置在圆孔和外螺纹之间，用于保持端子螺钉，使得外螺纹的末端与端子板间隔一定距离; 以及用于当所述外螺纹的末端联接到相应的端子条时分别从所述引导部分释放所述引导板部分的摆动机构，以允许所述垫圈摆动。
