Description
Technical field
The utility model relates to a kind of relay, particularly relates to a kind of clapper-type electromagnetic relay.
Background technology
Existing clapper-type electromagnetic relay generally adopts pair of contact, because structural limitations, the relay contact gap can not be excessive; When relay broke off, because the arcing phenomenon between the contact, the contact sticked together easily; Can not drive high power load; Particularly its contact is prone to take place sticking limit in large-scale truck, motorcycle and high-power start equipment, and relay is stable inadequately, and anti-vibration and impact capacity are not strong.
The utility model content
For solving the problem that exists in the prior art, the utility model design provides a kind of clapper type relay, has solved the arcing phenomenon between the contact, improves the load capacity of clapper-type electromagnetic relay.
The technical scheme of the utility model is: a kind of clapper type relay, include seat board, outer cover, motion-limiting sheet, moving contact, reed, break, soft whipping wire, magnet steel, armature, iron core, carriage, coil block, iron yoke, spring, and the winding wiring sheet, sheet confluxes; The Kong Yutie yoke that passes coil block wherein unshakable in one's determination connects; Moving contact and reed riveted joint, reed and armature riveted joint, the break and the sheet riveted joint of confluxing; The winding wiring sheet is connected with coil block; Soft whipping wire is connected with motion-limiting sheet with reed, and spring is connected with the iron yoke with armature, above moving contact and break, is provided with magnet steel.
The relay operation principle of the utility model mainly is: when relay is in off-state; Coil voltage gradually raises; Relay converts attracting state into by off-state, and after the relay adhesive, the loop, contact is connected; Be specially: the motion-limiting sheet → moving contact → reed → fixed contact → sheet that confluxes, thereby make contact loop.Reduce the coil voltage gradually; Relay converts off-state into by attracting state, and contact current flows to fixed contact by moving contact, and the electric arc direction is from moving contact and flows to fixed contact; The magnetic field that provides by the permanent magnet magnet steel on contact next door; Electric arc when blowing the disconnection of disconnected loop, contact, the motion of motion-limiting sheet restriction reed realizes its conversion and control effect.
The beneficial effect of the utility model relay is: the clapper-type electromagnetic relay that the strong high-power band magnetic blow-out of a kind of overload capability is provided; Utilize the magnetic field of contact annex; Effectively blow the outage arc; And have the movable contact spring stopping means, and make it in large-scale truck, motorcycle and high-power start equipment, played starting and control action.Realized the application of relay in powerful device.
Description of drawings
Fig. 1 is the overall structure figure of the relay of the utility model;
Fig. 2 is the relay seat board sketch map of the utility model,
Among the figure: the 1-seat board, the 2-outer cover, the 3-motion-limiting sheet, the 4-moving contact, the 5-reed, the 6-break, the 7-soft whipping wire, the 8-magnet steel, 9-armature, 10-is unshakable in one's determination, 11-bracket, 12-coil block, 13-iron yoke, 14-return spring, 15-winding wiring sheet, 16-backflow sheet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further to detail.
A kind of clapper type relay includes seat board 1, outer cover 2, motion-limiting sheet 3, moving contact 4, reed 5, break 6, soft whipping wire 7, magnet steel 8, armature 9, unshakable in one's determination 10, carriage 11, coil block 12, iron yoke 13, spring 14, and winding wiring sheet 15, sheet 16 confluxes; Wherein iron core 10 passes Kong Yutie yoke 13 connections of coil block 12; Moving contact 4 and reed 5 riveted joints, reed 5 and armature 9 riveted joints, the break 6 and sheet 16 riveted joints of confluxing; Winding wiring sheet 15 is connected with coil block 12; Soft whipping wire 7 is connected with motion-limiting sheet 3 with reed 5, and spring 14 is connected with iron yoke 13 with armature 9, above moving contact 4 and break 6, is provided with magnet steel 8.
The relay operation principle of the utility model is: by motion-limiting sheet 3 restriction reeds 5, rest on definite position when reed 5 is returned at every turn, the contact current passage is: motion-limiting sheet 3 → moving contact 4 → reed 5 → fixed contact 12 → sheet 16 confluxes.When leading to rated voltage for winding wiring sheet 15, coil gets electric, generates an electromagnetic field; 10 pairs of armature of the iron core that is magnetized 9 produce suction, and armature 9 drives reed 5 motions, and moving contact 4 is communicated with fixed contact 6; At last, motion-limiting sheet 3 is connected with the sheet 16 that confluxes, and load gets the electrician and does.When giving 15 outages of winding wiring sheet, coil block 12 magnetic field diminishes, 10 degaussings unshakable in one's determination; The suction that armature 9 is produced disappears, and armature 9 drives reed 5 motions, and moving contact 4 and fixed contact 6 are broken off; Motion-limiting sheet 3 breaks off with the sheet 16 that confluxes, and the load circuit outage produces electric arc between moving contact 4 and the fixed contact 6; The electric arc direction under the effect in magnet steel 8 magnetic fields, promptly forms the magnetic blowout phenomenon from moving contact 4 to fixed contact 6.
