Abstract

The invention discloses a straight-pulling type magnetic latching relay, comprising an electromagnetic system, a contact group and an anti-magnetic cover, wherein the electromagnetic system comprises a cover shell, an upper cover, a coil skeleton, a first yoke iron, a second yoke iron, an iron core, a connecting rod, a terminal pin, a first pushing piece, a second pushing piece, an auxiliary reed and a movable reed, wherein the coil skeleton, the first yoke iron and the second yoke iron are arranged in a cavity enclosed by the anti-magnetic cover; the anti-magnetic cover is arranged in a cavity enclosed by the cover shell and the upper cover; two pieces of magnetic steel are arranged at the middle part of the coil skeleton; the connecting rod is fixed in the iron core; the terminal pin penetrates through the coil skeleton; the iron core is inserted into the coil skeleton; and a coil on the coil skeleton is connected with an external power supply by the terminal pin. The straight-pulling type magnetic latching relay manufactured by adopting the technical scheme has the advantages that strong-magnetic interference can be effectively prevented; and since the magnetic latching relay is a straight-pulling type electromagnetic system, the strong-magnetic interference can be effectively prevented by adding the anti-magnetic cover, and the condition that the work can not be carried out due to strong-magnetic interference can not occur under the standard of the state grid.

Description

technical field

[0001] The invention relates to the field of relays, in particular to a straight-pull magnetic latching relay. Background technique

[0002] Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. At present, the core of the magnetic latching relay drive system used in the market is the rotary conversion magnetic circuit mode. This kind of working mode makes it inconvenient to add a magnetic shield inside, and a lot of materials are needed to add a magnetic shield outside. Therefore, there is an urgent need for an effective Latching relays that prevent strong magneti...
