Positive stop lug boss, the contact are supported to be equipped with to two sides extension and buffer insulation partition corresponding with dynamic iron core, the insulation
Dynamic iron core and positive stop lug boss are spaced by buffer dividing plate.
The buffer insulation partition is equipped with two limit ribs disposed in parallel, the dynamic iron core be located at two limit ribs it
Between, it limits and cooperates with limit rib.
The contact supports to be equipped with the arc baffle perpendicular to buffer insulation partition, the positive stop lug boss be equipped with every
The corresponding groove of arc baffle, the arc baffle and groove form mating structure.
The contact supports to be equipped with several contact supportings being set side by side for installing moving contact, on the contact is supported
It is additionally provided with each contact supporting first partition spaced apart from each other.
The pedestal is equipped with each static contact second partition spaced apart from each other, the first partition and second partition phase
Mutually it is staggered.
The contact is additionally provided with indicating arm on supporting.
The beneficial effects of the utility model are: buffer insulation partition is wholely set in contact support using above scheme,
Dynamic iron core and positive stop lug boss are spaced, therefore when dynamic iron core reset, cooperated by buffer insulation partition and positive stop lug boss limit,
Buffer insulation partition can extenuate significantly impact force when dynamic iron core and positive stop lug boss collision using itself toughness, to improve product
Mechanical life, while the buffer insulation partition can also completely cut off dynamic iron core and dynamic/static contact, electricity when preventing dynamic/static contact disjunction
Arc is moved to dynamic iron core direction.

Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, a kind of A.C. contactor, including pedestal 1 and the electromagnetic system being arranged in pedestal 1 and contact system
System.
The electromagnetic system includes dynamic iron core 2, magnetic yoke, coil rack, coil, reset spring, and 2 activity of dynamic iron core is set
It sets, when the coil is energized, magnetic yoke can generate a suction and be adsorbed on magnetic yoke so that dynamic iron core 2 overcomes the elastic force of reset spring
On, when the coil is de-energized, dynamic iron core 2 then resets under the action of reset spring.
The contact system includes that contact supports 3, moving contact 4, static contact 5, and the static contact 5 is fixedly mounted on pedestal 1
On, the moving contact 4 is installed contact and is supported on 3, and corresponding with static contact 5, and the contact supports 3 settings movable up and down
It is connected in pedestal 1, and with dynamic iron core 2, contact supports that 3 can move up and down with dynamic iron core 2, so that moving contact 4 is driven to act,
Realize the connection and disconnection with static contact 5.
The pedestal 1 is equipped with positive stop lug boss 11 corresponding with 2 both ends of dynamic iron core, to dynamic when for contactor release
The limit that iron core 2 acts, the contact support 3 to be equipped with to two sides extension and buffer insulation partition corresponding with dynamic iron core 2
31, dynamic iron core 2 and positive stop lug boss 11 are spaced by the buffer insulation partition 31, therefore when the reset of dynamic iron core 2, slow by insulating
It rushes partition 31 and the limit of positive stop lug boss 11 cooperates, buffer insulation partition 31 can extenuate significantly the reset of dynamic iron core 2 using itself toughness
When with positive stop lug boss 11 collide impact force, to improve the mechanical life of product.
Meanwhile the buffer insulation partition 31 can also completely cut off dynamic iron core 2 and dynamic/static contact, electricity when preventing dynamic/static contact disjunction
Arc is moved to 2 direction of dynamic iron core, is improved product service performance, is improved service life.
Further, two limit ribs 32 disposed in parallel, the dynamic iron core 2 are equipped on the buffer insulation partition 31
It between two limit ribs 32, limits and cooperates with limit rib 32, dynamic iron core 2 is limited by limit rib 32, reduce and produce
2 mode of dynamic iron core is swung product when in use, further increases product service performance.
As shown, the contact supports 3 to be equipped with the arc baffle 33 perpendicular to buffer insulation partition 31, the limit
Boss 11 is equipped with groove 12 corresponding with arc baffle 33, and the arc baffle 33 forms mating knot with groove 12
Structure.
Arc baffle 33 and positive stop lug boss 11 can not only play the effect of arc, prevent electric arc string arc, and arc is kept off
Plate 33 and groove 12 form grafting limit and cooperate, and further support 3 up and down action to play the work of a positioning and guiding contact
With movement is more steady to stablize, and further increases product service performance.
Further, it supports to be equipped with several contact supportings being set side by side for installing moving contact 4 on 3 in the contact
34, the contact is supported to be additionally provided on 3 by each contact supporting 34 first partition 35 spaced apart from each other, and the pedestal 1 is equipped with
By each static contact 5 second partition 13 spaced apart from each other, the first partition 35 and the interlaced setting of second partition 13 pass through
Each group contact is isolated jointly with second partition 13 in first partition 35, greatly improves arc effect, prevents electric arc string arc, improves product
Service performance.
In addition, the contact is supported to be additionally provided with indicating arm 36 on 3, support 3 settings integrated indicating arm 36 and contact
Structure, the structure greatly simplified, cost is lower.
Embodiment is not construed as the limitation to utility model, but any spiritual improvements introduced based on the utility model,
