It touches and is contradicted on limited block in the upper end of fixing bracket lower end, compression spring, the moving contact is set in fixing bracket, and dynamic tactile
Card slot is provided on the upper surface of head, support bracket fastened upper end is installed in card slot, and moving contact can be pressed on by fixing bracket
On contact rack.
The advantageous effect of above structure is：The A.C. contactor have it is simple in structure, stable and reliable for performance, assembling it is convenient,
Moving contact can be compressed on contact rack, when assembling moving contact, only needed by the advantages of maintenance cost is low, the fixing bracket of fixation kit
Fixing bracket is pulled upwardly, fixing bracket compression press spring, then moving contact is set in fixing bracket, fixing bracket is touched with dynamic
Card slot on head fastens, and unclamps fixing bracket, and moving contact is pressed on contact rack by compression spring driving fixing bracket, you can is completed
The assembling of moving contact, consequently facilitating the dismounting of moving contact, after moving contact damages, it is also very convenient to replace moving contact.
Particularly, the static contact includes the connecting portion and contact site that are fixed on the terminal plate of pedestal, contact site
Upper surface is provided with stationary contact, and supporting rack is provided on the upper surface of the connecting portion, contact is corresponded on one end of supporting rack
Blocked hole is provided at portion, the contact site of the static contact is installed in blocked hole and forms the clamping of static contact and supporting rack
Cooperation.Supporting rack can play a supporting role to the contact site of static contact, avoid contact with portion and deform when by external impacts,
So as to improve the reliability of A.C. contactor work.
