Publication number: 20230005692Abstract: In an electromagnetic relay device, a mover includes a movable contact movable to abut onto and separate from a stationary contact through a contact region defined between the movable and the stationary contacts. A plunger causes the mover to reciprocate to accordingly cause the movable contact to abut onto or separate from the stationary contact. A solenoid unit of the electromagnetic relay device includes an electromagnetic coil, a movable core, and a support member that slidably supports an outer peripheral surface of a slidable contact portion of the movable core. A movable wall member is located between the slidable contact portion and the contact region. The movable wall member reciprocates together with the plunger. The movable wall member is arranged to occupy a region in the electromagnetic relay device. The region contains at least the slidable contact portion when viewed in the reciprocation direction.Type: ApplicationFiled: September 8, 2022Publication date: January 5, 2023Applicants: DENSO CORPORATION, DENSO ELECTRONICS CORPORATIONInventors: Masahiro TANIMOTO, Mitsugu FUJIWARA, Hiroshi NAGURA, Makoto KAMIYA

Patent number: 10916398Abstract: An electromagnetic relay includes a mobile component movable at time of energization and de-energization of a coil, and a fixed component immovable at the time of energization and de-energization of the coil. A damping space is provided between the mobile component and the fixed component and changes in volume with the movement of the mobile component. A gap provided between the mobile component and the fixed component serves as a passage that allows gas to flow into or out of the damping space when the damping space changes in volume. A size of the gap is set such that a pressure is generated in the damping space to cause a damping force acting on the mobile component when the damping space changes in volume.Type: GrantFiled: January 16, 2019Date of Patent: February 9, 2021Assignee: DENSO ELECTRONICS CORPORATIONInventors: Wataru Mizuno, Tomoaki Tanaka, Makoto Kamiya
