An interior of the housing has an accommodation space, and each contact module includes a terminal assembly, a movable contact plate, and a drive assembly. The terminal assembly includes two terminals spaced apart and disposed on the housing. The terminal at least partially extends into the accommodation space to form a static contact. The movable contact plate is movably disposed in the accommodation space, and is configured to contact two static contacts to conduct the two terminals. The drive assembly includes a drive shaft and a drive unit that drives the drive shaft. The drive shaft is connected to the movable contact plate, and the drive unit is configured to drive the movable contact plate via the drive shaft. Multiple drive shafts corresponding to the multiple contact modules are disposed coaxially, and are relatively movable in their axial direction.

Abstract: A relay includes: a housing, a base plate, and a driving device, connected to the base. At least one stationary contact group is provided on the housing. The stationary contact group includes two stationary contacts insulated from each other. At least one stationary contact in the stationary contact group includes an upper terminal and a lower contact are included. The upper terminal and the lower contact are isolated from each other and electrically connected by a fuse. The base plate is provided in the housing and can switch between on and off positions. The base plate, when being in the on position, contacts the stationary contact group for the electrical conduction of the two stationary contacts in the stationary contact group, and, when being in the off position, is isolated from the stationary contact group for disconnecting the electrical conduction of the two stationary contacts in the stationary contact group.

Abstract: A relay includes a housing, a contact assembly and an auxiliary contact assembly. The contact assembly includes the movable contacts adapted to move towards or away from the stationary contacts under the driving of the movable contact bridge. The auxiliary contact assembly includes an auxiliary contact bridge and auxiliary contacts. At least portion of each of the auxiliary contacts extends into the housing. The auxiliary contact bridge moves synchronously with the movable contact bridge to be selectively and electrically connected to the auxiliary contacts. The housing includes a top surface spaced apart from the stepped portion in the movement direction of the movable contact bridge or the auxiliary contact bridge. The stationary contacts are arranged on the top surface of the housing. The portion of each of the auxiliary contacts arranged outside the housing is arranged on each of the stepped portions.
