Description

Technical Field

[0001] The utility model relates to the technical field of relays, and more specifically, to a connection structure of an electromagnetic relay push piece.

Background Art

[0002] In recent years, with the rapid development of the electronic information industry, relays, as basic components, have been widely used in automation control fields such as home appliances, communications, automobiles, instrumentation, machinery, and aerospace. The latest statistical data shows that among electronic component products, relays have become the largest product in terms of annual sales. The magnetic latching relay is a connection structure of an electromagnetic relay push piece developed in recent years. As one of the important components for intelligent control, it plays an important role. Like other electromagnetic relays, it automatically connects and disconnects the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay completely depends on the action of the permanent magnet, and the conversion of its switch state is triggered by a pulse electrical signal with a certain width and completed. It has the characteristics of power saving, stable performance, small size, large load capacity, and superior performance compared with other relays. Therefore, magnetic latching relays are increasingly widely used.

[0003] An existing magnetic latching relay that is convenient for maintenance, with a publication number of CN 115440539 A, includes a housing. One side of the housing is provided with an insertion interface, and a mounting seat is detachably arranged inside the housing. The mounting seat is inserted into the housing through the insertion interface. The mounting seat is provided with an armature assembly, a coil for controlling the swing of the armature assembly, and a moving contact piece and a static contact piece arranged opposite to each other. A connecting piece is arranged between the armature assembly and the moving contact piece. The armature assembly is connected to the moving contact piece through the connecting piece, and the armature assembly is used to drive the moving contact piece to swing. The connection performance between the armature assembly and the connecting piece of this kind of magnetic latching relay is poor. The connecting piece is easy to move at the connection point and will fall when suspended, resulting in the destruction of the integrity of the relay and affecting its use.
