Problems solved by technology

[0002] The article "Magnetic Latching Relays and Its Application in Portable Devices" published by Wang Xiaohong et al. in the second issue of "Magnetic Materials and Devices" in 2004 introduced pulse-controlled relays with self-holding functions and all magnetic latching relay products such as JE22 -B, WJ301-1A and other products do not have arc extinguishing devices such as grids, so the breaking capacity and electrical life of the products are relatively low

Abstract

The related magnetic latching relay with grating sheet comprises: a body; on the body, a moving and fixed contact head, an electromagnetic drive mechanism with permanent magnet to conduct or separate two contact heads. Wherein, some iron grating sheets are set between contact heads along running direction of the moving contact head. This invention generates cathode effect to accelerate arc-extinguishing, and improves performance of the relay.

Description

Technical field: [0001] The invention relates to a magnetic latching relay with a grid sheet, which belongs to the technical field of low-voltage electrical appliances. Background technique: [0002] The article "Magnetic Latching Relays and Its Application in Portable Devices" published by Wang Xiaohong et al. in the second issue of "Magnetic Materials and Devices" in 2004 introduced pulse-controlled relays with self-holding functions and all magnetic latching relay products such as JE22 -B, WJ301-1A and other products do not have arc extinguishing devices such as grids, so the breaking capacity and electrical life of the products are relatively low. Invention content: [0003] The object of the present invention is to provide a magnetic latching relay with a grid, which can strengthen the arc extinguishing ability of the contact system of the magnetic latching relay, thereby improving the breaking capacity and electrical life index of the magnetic latching relay. [000...
