The structure, connection manner and functional relationship of each main component of the relay proposed in the present disclosure will be described in detail below with reference to the above-mentioned drawings.

As shown in fig. 1 to 6, in an embodiment of the present disclosure, one end of the first reed 210 in the second direction Y is provided with a movable contact 213 toward one side of the second reed 220, and the other end of the second reed 220 in the second direction Y is provided with a movable contact 221 toward one side of the first reed 210, the two movable contacts 213, 221 and the opposite reeds respectively form two sets of contact structures, i.e., each set of contact structures includes one movable contact and one end of the one reed in the second direction Y arranged corresponding to each other, and the two sets of contact structures are arranged at both ends of the first reed 210 and the second reed 220 at intervals in the second direction Y. One set of contact structures is used for current carrying and the other set of contact structures is used for arc extinguishing. On this basis, the movable contact 213 of the first reed 210 and the end of the corresponding second reed 220 together form an arcing terminal contact set M1, the movable contact 221 of the second reed 220 and the end of the corresponding first reed 210 together form a current-carrying terminal contact set M2, and hereinafter, for convenience of description and reference, the movable contact 213 of the contact structure for arc extinction (i.e., the arcing terminal contact set M1) is referred to as a first movable contact, a position of the side of the first reed 210 facing away from the second reed 220 corresponding to the movable contact 213 is provided with an anti-shake elastic member 300, and the anti-shake elastic member 300 includes a connecting portion 310 and a first abutting portion 321. The connection portion 310 is connected to the first reed 210. The first contact portion 321 extends obliquely from the connecting portion 310, and on the reference surface, the front projection of the first contact portion 321 is located outside the front projection of the connecting portion 310, with the surface of the first reed 210 facing away from the second reed 220. Accordingly, the relay according to the present disclosure can be abutted against the groove wall 111 of the accommodating groove 110 by the first abutment portion 321 of the anti-shake elastic member 300 when the first reed 210 breaks a load. Through the above design, the present disclosure can be applied to the relay in which the contact assembly 200 adopts the double-contact structure, on this basis, the elastic buffering and anti-shake functions of the contact structure on the arc extinguishing side are realized, and the anti-shake elastic member 300 adopts the design that the first abutting portion 321 extends obliquely and abuts against the groove wall 111 of the accommodating groove 110 formed in the housing 100 when the first reed 210 breaks the load, thereby being capable of optimizing the anti-shake buffering effect. In addition, since the anti-shake elastic member 300 is only disposed at the contact structure of the arc extinguishing side, the number of parts can be further reduced and the structural complexity can be simplified on the basis of realizing the function of preventing arcing. It should be noted that, in an embodiment of the present disclosure, in order to further satisfy the respective functional requirements of the arcing terminal contact set M1 and the current-carrying terminal contact set M2, the contact gap of the arcing terminal contact set M1 may be larger than the contact gap of the current-carrying terminal contact set M2, that is, the gap between the moving contact 213 and the stationary contact 222 is larger than the gap between the stationary contact 214 and the moving contact 221.

Specifically, fig. 4 shows the engagement of the pusher card with the second abutment 322 during assembly, and fig. 5 shows the positional engagement relationship with the second abutment 322 when the pusher card 400 is assembled in place. The abutting part of the second abutting part 322 and the pushing card 400 may adopt a bilateral guiding structure, for example, the second abutting part 322 may have a bending part, further the bending part may be an arc bending structure, and the corresponding position of the pushing card 400 may be provided with a guiding inclined plane, and the second abutting part 322 abuts against the guiding inclined plane with the bending part, thereby forming a bilateral guiding function, so that the assembly process of the pushing card 400 is more convenient. In addition, the push card 400 is not shown in the structure shown in fig. 1 and 2 due to the shielding of the housing 100, and the push card 400 may be partially accommodated in a slot of the housing 100, for example. Through the above structural design, the present disclosure can enable the first reed 210 to realize deformation with guiding function by using the abutment of the anti-shake elastic member 300 and the push card 400 during the assembly process, thereby ensuring that the first reed 210 is assembled in place.
