Process introduction
The working principle of ac contactor is to make use of electromagnetic force and spring force to realize the connection and break of contact.There are two working states of ac contactor: power loss state (release state) and power gain state (action state).When the attraction coil is energized, the static iron core generates electromagnetic suction, the armature is attracted, and the connecting rod connected with the armature drives the contact, so that the normally closed contact contact is in the state of electricity.When the suction coil is cut off, the electromagnetic suction disappears, the armature is re-opened, the normally open contact is closed, the position spring is released, all contacts are then reset, and the contactor is in a state of loss of power.
This type of contact is more, the current range is also relatively wide, there are rivet contact, sheet contact
Production capacity
Rivet contacts typically have a period of 7 to 10 days,
The production cycle of sheet contact is 15 to 20 days
We have 300 sets of rivet production machine, more than 40 sets of punch, production capacity is sufficient
Packaging and service
we have a special grinding and polishing process for the post-treatment to ensure that the contact is free of burr and copper chips. At the same time, we use imported contact protective agent to improve the contact resistance
The packing method of the contact is vacuum, the contact is in line with the international environmental protection ROHS and REACH standards, the packaging bag is in accordance with ROHS and REACH standards for purchase
Quality guarantee
The raw materials of each batch will be selected during the incoming inspection, and the daily production status will be recorded during the process inspection and finished product inspection to ensure the qualified rate
