Description
Technical field
The present invention relates to contactor technical field, more particularly between the wire connection terminal and coil rack of a kind of contactor
Connection structure.
Background technology
Contactor is that one kind flows through current induced magnetic field using coil, makes contact closure, to reach the electric appliance of control load.
After contactor coil is powered, coil current can produce magnetic field, and the magnetic field of generation makes static iron core produce the dynamic iron of electromagnetic attraction attraction
Core, and drive ac contactor contact to act, normally-closed contact disconnects, normally opened contact closure, both are linkages.Work as coil blackout
When, electromagnetic attraction disappears, and armature discharges under the action of release spring, restores contact, and normally opened contact disconnects, and normally-closed contact closes
Close.
A kind of contactor of the prior art generally includes wire connection terminal and coil rack, and Fig. 1 is the contactor of the prior art
Coil rack D structure schematic diagram, Fig. 2 is the section view of the slot position in the coil rack of the contactor of the prior art
