Embodiment

To combine the accompanying drawing in the utility model below, the technical scheme in the utility model is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of relay, and this relay dielectric strength is high, and the anti shock and vibration performance is high, good reliability.

Describe in detail below in conjunction with description of drawings.

See also Fig. 1, Fig. 2, the structural representation of a kind of relay that Fig. 1 provides for the utility model; Fig. 2 is the end view of the A-A ' direction of relay shown in Figure 1.Like Fig. 1, shown in Figure 2, this relay can comprise: iron core 1, yoke 2, armature 3, coil 4, moving contact 5, fixed contact 6, M terminal assemblies 7 and movable contact spring 8.

For the stability and the reliability that increase relay, relay can also comprise:

Base plate 9.As shown in Figure 1, spacing module 90 is arranged on the base plate 9, the position that spacing module 90 is provided with is near armature 3 places.Spacing module 90 is used to limit the position of armature 3, prevents that armature 3 breaks away from yoke 2, avoids relay the phenomenon of leakage field to occur, reduces magnetic loss.Spacing module 90 guarantees effectively that through the position of restriction armature 3 armature 3 and yoke 2 fit tightly, thereby has strengthened the reliability and stability of relay.

Wherein, the contour structures of spacing module 90 can be any regular shape, does not break away from yoke 2 as long as spacing module 90 can limit the position of armature 3, and the utility model does not limit.Preferably, spacing module can be a cuboid.
