The strong clapper-type great-power electromagnetic relay being mainly used in large-scale truck, motorcycle and high-power start equipment of ability
Device.
Background technology
Existing clapper-type electromagnetic relay uses a pair of contact, and because structure limits, relay contact gap can not mistake
Greatly, when relay disconnects, due to the phenomenon of arc discharge between contact, contact easily sticks together, it is impossible to drives high power load.
The content of the invention
It is to be solved by this invention to be:When relay disconnects, due to the phenomenon of arc discharge between contact, contact easily occurs
Adhesion, it is impossible to drive the technical problem of high power load.
In order to solve the above technical problems, the present invention is realized using following technical scheme：
A kind of clapper type relay with arc extinguishing auxiliary contact, include seat board, outer cover, motion-limiting sheet, active contact, reed, master
Stationary contact, armature, iron core, coil block, iron yoke, return spring, winding wiring piece and the piece that confluxes；Wherein, it is unshakable in one's determination to pass through coil
The hole of component is connected with iron yoke, and reed rivets with armature, and winding wiring piece is connected with coil block, return spring and armature and iron
Yoke connects, and active contact rivets with reed, main stationary contact and piece riveting of confluxing；Also riveting has an auxiliary is dynamic to touch on the reed
Point, an auxiliary stationary contact is additionally provided with above the main stationary contact.
Using the beneficial effect of above-mentioned technical proposal:
1st, the present invention is protected main contacts, is made it in large-scale truck, motorcycle and high-power using auxiliary contact carrying electric arc
In starting device, starting and control action are served, realizes application of the relay in powerful device.
2nd, the load current passage of present invention optimization electromagnetic relay, is effectively improved contact current interruption ability, relay is reliable
Property it is high, resistance to electric arc ability is strong, and overload capability is strong.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As Figure 1-4, the present invention includes electromagnet system and contact system；Electromagnet system makes relay by exciting current
Device, which completes closure or disconnection action, electromagnet system, to be included：Iron core 8, coil block 9, iron yoke 10 and armature 7, they are constituted
The magnetic circuit of coil and magnet.Contact system includes：Motion-limiting sheet 3, active contact 4, reed 5, main stationary contact 6, return spring 11, remittance
Flow 13, auxiliary movable contact 14 and auxiliary stationary contact 15.Remaining is the seat board 1 and outer cover 2 for two systems of fixing.
The present invention has respectively installed an auxiliary contact additional near two main contacts, and during relay adhesive, main contacts first closes,
Auxiliary contact are closed again, and when relay discharges, main contacts first disconnects, and auxiliary contact disconnect again, and the arcing between contact mainly exists
Carried out between auxiliary contact, so as to protect main contacts, improve the use reliability of relay.Reed 5 is limited by motion-limiting sheet 3,
Rested on when reed 5 is returned every time in defined location.Contact current passage is：3 → active of motion-limiting sheet contact 4 → auxiliary is dynamic
Conflux 14 → reed of contact 5 → main stationary contact 6 → auxiliary stationary contact 15 → piece 13.
When leading to rated voltage to winding wiring piece 12, coil obtains electric, generation electromagnetic field, 8 pairs of armature of the iron core being magnetized
7 produce suction, and armature 7 moves with movable contact spring 5, auxiliary movable contact 14 is first connected with auxiliary stationary contact 15, then active contact
4 connect with main stationary contact 6, load to obtain electric work.
When being powered off to winding wiring piece 12, the electromagnetic field of coil block 9 disappears, 8 degaussings unshakable in one's determination, to being inhaled caused by armature 7
Power disappears, and armature 7 moves with movable contact spring 5, active contact 4 is first disconnected with main stationary contact 6, then auxiliary movable contact 14 with it is auxiliary
Stationary contact 15 is helped to disconnect again, load circuit power-off.Electric arc is not produced between the active contact 4 first disconnected and main stationary contact 6, then
Electric arc is produced between the auxiliary movable contact 14 and auxiliary stationary contact 15 of disconnection, therefore protects main contacts.
When relay is off, coil both end voltage is gradually risen, relay is converted to suction by off-state
Conjunction state, after relay adhesive, contact loop is connected, and is specially：Auxiliary movable contact 14 first connects with auxiliary stationary contact 15, then
Active contact 4 connects with main stationary contact 6, loads to obtain electric work.Coil both end voltage is gradually reduced, relay is turned by attracting state
Off-state is changed to, active contact 4 first disconnects with main stationary contact 6, then aids in movable contact 14 to break again with auxiliary stationary contact 15
Open, load circuit power-off.Electric arc is not produced between the active contact 4 first disconnected and main stationary contact 6, the auxiliary then disconnected is dynamic to be touched
Electric arc is produced between point 14 and auxiliary stationary contact 15, therefore protects main contacts.
