Patent number: 11587751Abstract: An electromagnetic relay and a terminal block each include a voltage converter. The voltage converter is located adjacent to a coil and electrically connected to first coil terminals and second coil terminals. The voltage converter converts a power supply voltage input through one of the first coil terminals to a set value different from the input power supply voltage and outputs the power supply voltage to an electromagnet through one of the second coil terminals.Type: GrantFiled: December 26, 2018Date of Patent: February 21, 2023Assignee: OMRON CORPORATIONInventors: Seiki Shimoda, Kenshi Hayashida, Takeshi Noguchi

Patent number: 10964504Abstract: The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.Type: GrantFiled: November 16, 2016Date of Patent: March 30, 2021Assignee: OMRON CorporationInventors: Seiki Shimoda, Yuichiro Teshima, Akira Tsurusaki

Patent number: 10714291Abstract: The pressing member is configured to move to an off-position and an on-position. When the pressing member is located at the off-position, the first contact and the second contact come into a non-contact state. When the pressing member is located at the on-position, the first contact and the second contact come into a contact state by press of the pressing member against the contact piece. The actuator moves the pressing member from the off-position to the on-position via an overshoot position located beyond the on-position. The contact piece includes a body, and a low rigidity portion having rigidity lower than rigidity of the body. The pressing member presses the low rigidity portion.Type: GrantFiled: November 16, 2016Date of Patent: July 14, 2020Assignee: OMRON CorporationInventors: Seiki Shimoda, Akira Tsurusaki
