Patent number: 11862424Abstract: The main body frame includes a first frame including a flexible protruding plate portion, a second frame facing the first frame in a first direction to form the housing section, and a snap-fit mechanism connecting the first frame to the second frame. The snap-fit mechanism includes a fitted portion provided on the flexible protruding plate portion and a fitting projection portion provided on a side wall of the second frame and fitting with the fitted portion. The fitting projection portion and the fitted portion are fitted by bringing the first and second frames into relative proximity in the first direction, and the fitting is released by relatively displacing the first and second frames in a second direction orthogonal to the first direction.Type: GrantFiled: November 23, 2021Date of Patent: January 2, 2024Assignee: FUJI ELECTRIC FA COMPONENTS & SYSTEMS CO., LTD.Inventors: Masashi Sekiya, Kouetsu Takaya, Koumei Hazawa, Shouta Kikuchi

Patent number: 11810743Abstract: A mechanical latching device of an electromagnetic contactor eliminates a need to adjust a gap between portions mechanically preventing returning of a latch support. A latch support includes a protrusion protruding laterally and formed with a latch surface facing a released side. A rotating member has one end side rotatably supported and the other end side biased toward the protrusion. When the latch support is on the released side, an outer peripheral surface of the other end side contacts with a tip of the protrusion to allow the latch support to be displaced to a closed side. When the latch support is on the closed side, the other end side rotates according to a position of the latch support in a displacement direction, and a tip surface faces the latch surface to mechanically prevent the latch support from returning to the released side at plural positions along the displacement direction.Type: GrantFiled: May 27, 2022Date of Patent: November 7, 2023Assignee: FUJI ELECTRIC FA COMPONENTS & SYSTEMS CO., LTD.Inventors: Koumei Hazawa, Ryotaro Ninagawa

Publication number: 20230016517Abstract: This auxiliary contact unit includes a case and a case that are divided from each other in the width direction. The case includes a side wall portion and a partition wall portion protruding from a wall surface of the side wall portion toward the case. The case includes a side wall portion having a wall surface with which a tip end of the partition wall portion comes into contact when the case is assembled to the case. A space surrounded by the side wall portion, the partition wall portion, and the side wall portion serves as a contact housing portion. The side wall portion includes a pass-by wall portion protruding from a wall surface toward the side wall portion along the partition wall portion.Type: ApplicationFiled: September 27, 2022Publication date: January 19, 2023Applicant: FUJI ELECTRIC FA COMPONENTS & SYSTEMS CO., LTD.Inventors: Shouta KIKUCHI, Kouetsu TAKAYA, Koumei HAZAWA, Ryotaro NINAGAWA
