RELAY
Document Type and Number:
WIPO Patent Application WO/2022/228346
Kind Code:
A1
Abstract:
A relay (99), comprising a housing (10) and a plurality of contact modules (21, 22). The interior of the housing has an accommodating space, and each contact module comprises a terminal assembly (211, 221), a movable contact plate (213, 223), and a driving assembly (215, 225). The terminal assemblies each comprise two terminals (2111, 2112, 2211, 2212) which are disposed at an interval on the housing, and the terminals at least partially extend into the accommodating space to form a static contact. Each movable contact plate is movably arranged within the accommodating space and used for making contact with two static contacts, so as to connect two terminals. The driving assemblies each comprise a driving shaft (2151, 2251) and a driving unit (2153, 2253) which drives the driving shaft, the driving shafts are connected to the movable contact plates, and the driving units are used for driving, by means of the driving shafts, the movable contact plates to make contact with or separate from the two terminals. The plurality of driving shafts corresponding to the plurality of contact modules are coaxially arranged, and the plurality of driving shafts may be relatively moved in the axial direction. The relay can separately control, by means of different driving units, different movable contact plates to move, individually control the on-off of different control loops, and merely occupy the space occupied by approximately one original relay, facilitating being lightweight and reducing costs.
