Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Refer to Fig. 1 to Fig. 5, this utility model magnetic latching relay magnetic structure includes: a coil rack 1, is sheathed on the solenoid 2 in the middle part of described coil rack 1 and is individually fixed in two yokes 3 at described coil rack 1 two ends, described magnetic structure also includes iron core 4 and at least two lead pin 5, described iron core 4 wears described coil rack 1 and two yokes 3, each yoke 3 is fillet near the end of iron core 4, and described coil rack 1 offers the blind hole 6 for described at least two lead pin 5 grafting.
Wherein, described coil rack 1 includes first side plate the 12, second side plate 14 of being oppositely arranged and is connected to the connection axle 16 between described first side plate the 12, second side plate 14, described solenoid 2 is sheathed on described connection axle 16, and described iron core 4 is fixing with two yokes 3 after running through described connection axle 16 to be connected.
Specifically, each yoke 3 includes bottom side portion 32 and by the vertically extending side portion 34 in described bottom side portion 32 one end, and described side portion 34 is partially housed in the first side plate 12 or the second side plate 14, and the end of described side portion 34 is fillet.Described iron core 4 is fixing with the side portion 34 of yoke 3 after running through described connection axle 16 to be connected.In the present embodiment, described bottom side portion 32 is parallel to described connection axle 16 and arranges.
Described blind hole 6 is opened on the second side plate 14, and described blind hole 6 is extended towards the medial surface of the second side plate 14 by the end face of described second side plate 14.In order to facilitate the grafting of described lead pin 5 to position, the blind hole 6 of described second side plate 14 end face is internal is additionally provided with hole 7, location.In the present embodiment, the width of described blind hole 6 and the width of lead pin 5 adapt, and described at least one lead pin 5 is two.
Referring to Fig. 1 to Fig. 5, this utility model magnetic latching relay magnetic structure is as follows in installation lead pin 5 process:
