Problems solved by technology

[0002] The electromagnetic relay mainly includes a shell, a contact system, a magnetic circuit system, etc. There is an armature connected between the magnetic circuit systems. After the magnetic circuit system is energized, the iron core in it will be attracted to the armature to realize the conduction of the internal circuit of the electromagnetic relay. A button that is in movable contact with the armature is often installed on the shell corresponding to the armature. The button of the electromagnetic relay is a switch for the debugger to detect whether the load end circuit of the relay is normal,

Abstract

The invention relates to the technical field of relays, and particularly relates to an electromagnetic relay with a button buffer mechanism. The electromagnetic relay comprises a shell, a button assembly and a contact system positioned in the shell, the shell is provided with a mounting seat for mounting the button assembly, the button assembly comprises a button and an elastic piece matched with the button, the bottom of the button is provided with a buffer key rod, and the buffer key rod can extend into the shell to be in movable contact with an armature so that a contact system is connected or disconnected, and the test work of a load end circuit of the electromagnetic relay is completed. The buffer key rod is provided with an action end which is in contact with the armature so that the buffer key rod can buffer and disperse the pressure generated by the action end and the armature which are pressed against each other. And the failure of the detection function of the on-off of the circuit of the electromagnetic relay caused by the breakage of the button due to overlarge and concentrated pressure is prevented.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an electromagnetic relay with a button buffer mechanism. Background technique [0002] The electromagnetic relay mainly includes a shell, a contact system, a magnetic circuit system, etc. There is an armature connected between the magnetic circuit systems. After the magnetic circuit system is energized, the iron core in it will be attracted to the armature to realize the conduction of the internal circuit of the electromagnetic relay. A button that is in movable contact with the armature is often installed on the shell corresponding to the armature. The button of the electromagnetic relay is a switch for the debugger to detect whether the load end circuit of the relay is normal, but the button in the prior art is a solid structure without buffering Function, when the button is subjected to external force, the button is directly in conflict with the armature rigidity, at this time,...
