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, the structural representation of a kind of relay that Fig. 1 provides for the utility model.Relay as shown in Figure 1, that the utility model provides comprises: iron core 1, yoke 2, armature 3, coil 4, moving contact 5, fixed contact 6 and movable contact spring 7.This relay can also comprise:

Push rod 8.See also Fig. 2, Fig. 2 is the structural representation of the push rod of relay shown in Figure 1.As shown in Figure 2, push rod 8 is designed to the block structure, can increase dielectric strength, compares with conventional means of relay, and the relay dielectric strength that the utility model provides has increased more than the 1000V.

See also Fig. 3, Fig. 3 is the structural representation of the movable contact spring of relay shown in Figure 1.As shown in Figure 3, movable contact spring 7 is provided with turnup structure 71.Particularly, be that push-rod hole on the movable contact spring 7 is designed to turnup structure 71.Wherein, an end of push rod 8 is inserted on the push-rod hole 70 of movable contact spring 7, and the other end is connected with armature 3.Turnup structure 71 on the movable contact spring 7 can reduce the friction between movable contact spring 7 and the push rod 8, has significantly reduced the break flour that produces because of friction between movable contact spring 7 and the push rod 8, has avoided the situation of relay loose contact to occur, and has strengthened the reliability of relay.And make the action of push rod 8 when drive movable contact spring 7 moves more flexible.

In the utility model, movable contact spring 7 can be formed by the copper alloy compacting.

Need to prove that the utility model does not limit the material of movable contact spring 7.It is a preferred embodiment that movable contact spring 7 is formed by the copper alloy compacting, only gives an example, and does not limit.
