Title:
MONOSTABLE CLAPPER RELAY HAVING PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2023/035151
Kind Code:
A1
Abstract:
Disclosed in the present invention is a monostable clapper relay having a permanent magnet. A technical solution is characterized by comprising an armature group, an iron core group, a yoke group and a base. A permanent magnet is provided in the yoke group, the permanent magnet being placed in a reserved hole of an armature fixing support. By means of using the hole in the armature fixing support to limit the permanent magnet, the permanent magnet and the yoke are closely attached, and fixation is achieved by magnetic attraction between the permanent magnet and ferromagnetic material. In the present invention, a permanent magnet structure is added to a magnetic circuit to provide release and retention force by means of the permanent magnetic circuit. After the armature starts to rotate, the permanent magnet holding force can be reduced rapidly due to a change of an air gap, facilitating the relay to increase pick-up speed. Moreover, a position limiting support is provided on the base, and when a contact has a sticking fault, this prevents simultaneous closing of normally open and normally closed contacts. Furthermore, a barrier wall is disposed on the position limiting support, which confines each set of moving and static contacts to separate compartments, thereby preventing contact bridging due to the breakage of a moving reed.
