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:
The present invention relates to a kind of magnetic latching relay with the grid sheet, present technique belongs to the low voltage electrical apparatus technology field.
Background technology:
" magnetic latching relay and the application in portable equipment thereof " literary composition that Wang Xiaohong etc. are published in " magnetic material and device " the 2nd phase in 2004 has been introduced and has been adopted pulse controlled relay and all magnetic latching relay product such as JE22-B with self-retaining function, products such as WJ301-1A, all do not have arc-control devices such as grid sheet, so indexs such as the breaking capacity of product and electric life are lower.
Summary of the invention:
The objective of the invention is to provide a kind of magnetic latching relay with the grid sheet, this device can be strengthened the arc extinguishing ability of magnetic latching relay contact system, thereby improves the breaking capacity and the electric life index of magnetic latching relay.
The object of the present invention is achieved like this, it comprises body, be located at the dynamic and static contact on the body, with the electromagnetic drive mechanism that has permanent magnet of connecting or separating in order to drive moving contact and fixed contact, it is characterized in that, be provided with between dynamic and static contact iron railings sheet in order to arc extinguishing at the side of moving contact traffic direction line.
Separate with fixed contact when the electromagnetic drive mechanism that has permanent magnet makes moving contact, the electric arc that open circuit produces is attracted by the iron railings sheet, enters the iron railings sheet, is cooled off by the iron railings sheet, and produces cathode effect, thereby can quicken arc extinction, cuts off circuit.
The electric arc that magnetic latching relay contact open circuit of the present invention produces attracts through the iron railings sheet, enter the iron railings sheet, cooled off, and produce cathode effect by the iron railings sheet, so can quicken arc extinction, indexs such as the breaking capacity of magnetic latching relay of band grid sheets and electric life have been improved; Have characteristics such as high breaking capacity, long electric life and reliable operation.
