摘要： A dust preventing device for an electromagnetic contactor prevents foreign matters accumulated on a foreign matter preventing wall from slipping off the wall due to vibrations of electromagnetic contactor. In a case where an arc extinguishing chamber cover is disposed to cover a fixed contact and a movable contact, and includes a foreign matter preventing wall provided under a gas discharging opening formed on the cover, the foreign matter preventing wall is formed with ribs provided therearound in a shape of an embankment. Therefore, foreign matters having entered through the gas discharging opening can be positively trapped in a hollow portion surrounded by ribs, so that the foreign matters do not fall into the electromagnetic contactor from the foreign matter preventing wall due to vibrations of the contactor.

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： 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： An electromagnetic contactor is formed of upper and lower cases. Recesses are formed on opposite sides of the upper case, while guide walls that fit the recesses are provided on two opposite sides of the lower case to extend toward the upper case. The recesses and the guide walls can be fitted together even when the upper case is rotated by 180.degree. relative to the lower case. Therefore, the upper and lower cases can be attached to each other even if the upper case is rotated by 180.degree. relative to the lower case.
