The free end of the armature is also provided with a hooked salient for hooking the second face of the dynamic spring. The structure ensures that force arm of the dynamic spring created when a normally-closed contact is closed is longer than that of the dynamic spring created when a normally open contact is closed, provides auxiliary contact pressure when the normally open contact is closed, or provides pre-pressure when the normally-closed contact is closed, thereby improving performances of electromagnetic relays.
Description
Technical field
The present invention relates to a kind of electromagnetic relay, particularly relate to a kind of moving spring armature component of electromagnetic relay.
Background technology
Electromagnetic relay is widely used in the automatic control equipment, because the needs of development in science and technology require relay construction compacter, volume is littler, and sensitivity is higher, and functional reliability is higher.Usually the electromagnetic relay that links together for armature and moving spring, when the closing of contact, the arm of force of moving spring divides two kinds: a kind of is after coil powers up the relay execution, when relay is in operate condition, this moment the normally opened contact closure, the moving spring arm of force for the tie point of moving spring and armature to the distance between moving contact; Another kind is after the execution of coil cut-off relay, when relay is in the release condition involution state of magnetic latching relay (or for), this moment the normally-closed contact closure, the arm of force of moving spring be the armature end of close contact to the distance between moving contact, or identical with first.General this situation is for normally-closed contact, can be short, rigidity is strong because of the moving spring arm of force, and have the contact bouncing of severity when making normally-closed contact closed; And for normally opened contact, can be long, flexible big because of the moving spring arm of force, and need moving spring deflection could guarantee that enough pressure is arranged on the normally opened contact greatly.Make the normally-closed contact end of relay not control than heavy load like this, and be to guarantee normally opened contact pressure, need the armature motion distance longer, thereby need coil power dissipation bigger to guarantee that armature can grow apart from moving.Fig. 1 is the structural representation of the moving spring armature component of prior art, this moving spring armature component comprise drive contact 61 ' moving spring 6 ' and armature 3 ', moving spring 6 ' and armature 3 ' by tie point 63 ' be fixed together, when relay is in operate condition, this moment the normally opened contact closure, the moving spring arm of force for the tie point 63 of moving spring and armature ' arrive moving contact 61 ' distance; When relay is in release condition, this moment the normally-closed contact closure, moving spring 6 ' the arm of force be near the contact armature end 64 ' arrive moving contact 61 ' distance, or for the tie point 63 of moving spring and armature ' arrive moving contact 61 ' distance, weak point when therefore, the arm of force during release condition is than action or identical.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of moving spring armature component of electromagnetic relay is provided, it is bigger when the arm of force of moving spring is more closed than normally opened contact when making normally-closed contact closed, or when normally opened contact is closed, provide auxiliary contact force, or when normally-closed contact is closed, provide precompression, thereby the performance of electromagnetic relay is improved.
