The relay is an automatic control device with the function of controlling larger current output by using smaller input current, and is widely used in an electromechanical integrated automatic control system. Most of the existing relays adopt a pair of fixed contacts and a pair of movable contacts to realize the opening and closing of the relay in a matched mode, and further control of the relay on a circuit system is realized. However, when the contacts in the relay are opened and closed, arc sparks are easily generated, the contacts are easily ablated under the action of the arc sparks, so that the contacts are oxidized to increase the contact resistance of the contacts, further the electric repulsive force among the contacts is increased, and the connection stability of the contacts is affected. In the related art, the contact of the relay can be protected by a plating layer, so that ablation and oxidization of the contact are reduced, but the cost of the plating layer is higher, and the contact is easy to fail and fall off due to repeated opening and closing of the contact under the long-time operation of the relay, so that the service life of the relay is lower, and the practicability and reliability of the relay are reduced. In view of the above, the present utility model proposes a relay 100.

When the lifting mechanism 50 drives the conducting structure 30 to move along the direction away from the terminals 10 to disconnect the relay 100 from the circuit loop, the second conducting member 33 may be driven to leave the second abutting platform 13 of the terminals 10 and keep the first conducting member 31 abutting the first abutting platforms 11 of the two terminals 10, and after the second conducting member 33 completely leaves the second abutting platform 13 of the two terminals 10, the first conducting member 31 may be driven to leave the first abutting platforms 11 of the two terminals 10. At this time, after the first conducting member 31 completely leaves the first abutting platform 11 of the two leading-out ends 10, the two leading-out ends 10 are separated from each other by abutting and conducting the conducting structure 30, so that the power failure of the relay 100 is realized, and as the second conducting member 33 is away from the two leading-out ends 10 before the first conducting member 31, the electric arc generated when the conducting structure 30 and the leading-out ends 10 are separated acts between the first conducting member 31 and the first abutting platform 11, the second conducting member 33 is effectively prevented from being ablated and oxidized, the second conducting member 33 is further beneficial to mainly playing the role of current carrying, and the electric arc acts on the first conducting member 31 when the relay 100 is opened and closed, so that the first conducting member 31 is utilized to protect the second conducting member 33 from being oxidized, the contact resistance of the second conducting member 33 is prevented from being increased, the electric repulsive force between the conducting structure 30 and the leading-out ends 10 is effectively kept in a small range, the electric stability and the reliability of the relay 100 are improved, and the practicability and the structural reliability of the relay 100 are further improved.

When the lifting mechanism 50 drives the conducting structure 30 to move along the direction away from the leading-out end 10 to disconnect the relay 100, the lifting mechanism 50 can drive the second conducting member 33 of the conducting structure 30 to leave the second abutting platform 13 of the leading-out end 10 to disconnect the second conducting member 33 from the two leading-out ends 10, and then after the second conducting member 33 is stably disconnected from the two leading-out ends 10, the lifting mechanism 50 can further drive the first conducting member 31 to leave the first abutting platform 11 of the leading-out end 10 to disconnect the first conducting member 31 from the two leading-out ends 10. By using the lifting mechanism 50 to drive the first conducting element 31 and the second conducting element 33 of the conducting structure 30 to conduct the two leading-out ends 10 sequentially, the contact area between the conducting structure 30 and the two leading-out ends 10 can be increased under the connection and conduction action of the two conducting elements, and the contact resistance of the conducting structure 30 can be reduced; meanwhile, when the relay 100 is closed, the leading-out ends 10 are conducted by the first conducting piece 31, then the second conducting piece 33 is abutted against and conducted with the two leading-out ends 10, and when the relay 100 is disconnected, the second conducting piece 33 is separated from the two leading-out ends 10, and then the first conducting piece 31 is separated from the leading-out ends 10, so that an electric arc effect generated when the relay 100 is opened and closed can be generated between the first conducting piece 31 and the leading-out ends 10, the second conducting piece 33 only plays a current carrying effect, and the second conducting piece 33 is reduced to generate arc oxidation, stable connection conduction between the conducting structure 30 and the two leading-out ends 10 is guaranteed, contact resistance of the conducting structure 30 is smaller under the stable conduction effect of the second conducting piece 33, electric repulsive force between the conducting structure 30 and the leading-out ends 10 is reduced, and structural stability and reliability of the relay 100 are effectively improved.

Referring to fig. 2 and 4, in one embodiment of the present utility model, the first abutment platform 11 and the second abutment platform 13 are not on the same plane.

In this embodiment, the elastic pieces 311 and the connection contacts 313 may be made of materials with certain conductive properties, and the two elastic pieces 311 are respectively connected to opposite sides of the second conductive member 33, so that the two elastic pieces 311 and the second conductive member 33 form an integral conductive structure 30, thereby guaranteeing the integral current-carrying effect of the conductive structure 30. In the process that the lifting mechanism 50 drives the conducting structure 30 to move, the connecting contacts 313 on the elastic sheets 311 on both sides of the second conducting member 33 can be abutted to the first abutting platforms 11 of the two leading-out ends 10, so that the two leading-out ends 10 can realize the electrical conduction of the two leading-out ends 10 under the communication action of the two connecting contacts 313 and the conducting structure 30. After the two connection contacts 313 are respectively abutted to the first abutting platforms 11 of the two outgoing terminals 10, at this time, an arc action between the conducting structure 30 and the outgoing terminals 10 can act between the connection contacts 313 and the first abutting platforms 11, and further along with further movement of the lifting mechanism 50, the elastic sheet 311 can be compressed under the acting force of the lifting mechanism 50 and the outgoing terminals 10, so that the connection contacts 313 are stably abutted to the first abutting platforms 11 of the outgoing terminals 10, and at this time, the second conducting piece 33 can be driven to move to the second abutting platforms 13 abutted to the two outgoing terminals 10, so that the second conducting piece 33 conducts the two outgoing terminals 10, the contact area between the conducting structure 30 and the two outgoing terminals 10 is increased, the conducting structure 30 can stably and reliably realize electrical conduction of the two outgoing terminals 10, and the structural stability and reliability of the relay 100 are further improved.

Secondly, when the relay 100 realizes the outage of the circuit loop, the lifting structure drives the conducting structure 30 to descend, so that the elastic piece 311 can recover elastic deformation to drive the second conducting piece 33 to be away from the second abutting platforms 13 of the two leading-out ends 10, and then the connecting contact 313 is driven to be away from the first abutting platforms 11 of the two leading-out ends 10 under the further moving action of the lifting mechanism 50, so that the second conducting piece 33 is further prevented from being ablated and oxidized, the normal open and close control of the relay 100 is ensured, and the practicability and reliability of the relay 100 are further improved.

Further, in one embodiment of the present utility model, a portion of the connection contact 313 is exposed on a plane of the surface of the second conductive element 33 facing the terminal 10.
