Abstract

The utility model relates to an electromagnetic relay, which is composed of a seat composed of a winding barrel and the whole body of a base, a cover plate, an iron core, yoke iron, an armature, a pressure spring, a reed, a coil, and a casing. The yoke iron which is provided with a convex bract passes through an installing hole of the seat, and the yoke iron is riveted with the iron core which is inserted from the upper part of the winding barrel; the yoke iron is riveted with the pressure spring which causes the armature to be fixed onto a knife edge of the yoke iron; the reed is arranged on the seat, and the installing hole of the seat is covered by the cover plate and is filled and sealed. The pressure spring and the yoke iron are reliably fixed; filling and sealing materials do not penetrate the seat, however, the filling and sealing materials flow into the position of the pressure spring, and favorable sealing performance can be ensured.

Description

Electromagnetic relay

The utility model relates to a kind of electromagnetic relay.

Electromagnetic relay is a kind of electromechanical compo that is widely used in various electromechanical equipments, electrical equipment.Conventional electromagnetic relay comprises base, coil, yoke, armature, stage clip, reed and shell etc., and coil is wrapped on the spool (or skeleton), inserts iron core, contact-carrying on the reed in the spool.Existing a kind of relay product as shown in Figure 1, it has one by spool 11 and pedestal 12 integrally formed bases 1.In assembling, coil is wrapped on the spool 11 of base 1, yoke 4 is utilized protruding luxuriant 41 on it and stage clip 6 rivetings together, installing hole 13 from base 1 bottom passes again, and link together with the iron core 3 that inserts from spool 11 tops, armature 5 is placed on yoke 4 edges of a knife by stage clip 6 effects, form the magnetic circuit part.Again reed part 7 is fixed on the base 1.By excitatory, the degaussing of magnetic circuit part, making armature 5 is the rotating shaft rotation with the edge of a knife of yoke 4, promotes the folding of contact part 71.Be to guarantee the sealing and the fail safe of relay, the installing hole 13 of base 1 is carried out embedding, make potting compound 10 fill up installing hole 13 fully.But in above-mentioned relay,,, has a fixed gap between installing hole 13 and the yoke 4 for guaranteeing that stage clip 6 passes through smoothly because stage clip 6 and yoke 4 rivetings pass the installing hole of base after together.After the embedding, potting compound passes base 1, flow into stage clip 6 positions, influences the embedding effect.

Another kind of relay such as Fig. 2 after yoke 4 passes base installing hole 13, are installed on stage clip 6 on the yoke 4, and stage clip 6 does not fix by riveting with yoke 4.The installing hole 13 of this relay cooperates better with yoke 4, helps embedding.But 4 of stage clip 6 and yokes are fixing unreliable.

The purpose of this utility model provides a kind of energy secure fixation stage clip, can realize the relay of good seal performance again.

The utility model is made up of spool and the integrally formed base of pedestal, cover plate, iron core, yoke, armature, stage clip, reed, coil and shell by one, the yoke that has protruding bud passes the base installing hole, and be riveted together with the iron core that inserts from spool top, yoke is riveted together with stage clip again, stage clip is fixed in armature the knife-edge part of yoke, armature is free to rotate, forms the magnetic circuit part.Reed is loaded on the base, and the base installing hole is covered and embedding by cover plate.

The base installing hole can all be covered by cover plate, also can locally cover.

The yoke that the utility model will have protruding bud passes the base installing hole, is riveted together with the iron core that inserts from the spool top, and yoke is riveted together with stage clip again, and stage clip is fixed on the yoke knife-edge part with armature, makes the fixing very reliable of stage clip and yoke.In addition, after magnetic circuit part and reed installation, live parts such as yoke expose in the air, the protruding bud of the yoke of base installing hole passes part and still is through hole, no matter the base installing hole is adopted covering fully or local the covering, can both make potting compound not pass base, and flow into the stage clip position, thereby guarantee the utlity model has excellent sealing performance.

Fig. 2 is the structure chart of existing another kind of electromagnetic relay.

Fig. 3 is a structure chart of the present utility model.

Fig. 4 is yoke of the present utility model and stage clip riveted joint figure.

Fig. 5 is a understructure schematic diagram of the present utility model.

Fig. 6 is the upward view of base installing hole of the present utility model when not covered by cover plate.

Upward view when Fig. 7 is covered by cover plate fully for the base installing hole.

Fig. 8 is the base installing hole by the upward view that cover plate is local when covering.

As shown in Figure 3, yoke 4 passes installing hole 13 and is fixed together with the iron core 3 that inserts from spool 11 tops from the bottom surface of base 1, again with stage clip 6 (see figure 4)s with have protruding luxuriant 41 yoke 4 rivetings together, armature 5 is fixed in the edge of a knife of yoke 4 by stage clip 6, can freely rotate, more than promptly constitute the magnetic circuit part.The base 1 of again reed part 7 being packed into.Excitatory and the degaussing of magnetic circuit part is rotated armature 5, guarantees contact part 71 foldings.

As shown in Figure 5, base 1 is by pedestal 12 and spool 11 whole formation, and base 1 has an installing hole 13, and wherein 14,15 is the through hole that guarantees that yoke passes through smoothly.

After magnetic circuit system and reed part 7 installed, as shown in Figure 6, yoke 4 live parts such as grade exposed in the air, and the protruding bud of the yoke of installing hole 13 passes part 15 and still is through hole.For guaranteeing the sealing and the fail safe of relay, must carry out embedding to base installing hole 13.As shown in Figure 7, base installing hole 13 usefulness cover plates 2 are covered fully, around cover plate 2, carry out embedding again, guarantee that potting compound does not pass base 1, flow into stage clip 6 positions.Another kind of execution mode with base installing hole 13 usefulness cover plates 2 local coverings, reduces the gap of base 1 and yoke 4 as shown in Figure 8, again base installing hole 13 is carried out embedding, guarantees that potting compound does not pass base 1, flows into stage clip 6 positions.

Claims

1, a kind of electromagnetic relay, form by spool and the integrally formed base of pedestal, iron core, yoke, armature, stage clip, reed, coil and shell by one, it is characterized in that the yoke that has protruding bud passes the base installing hole, and be riveted together with the iron core that inserts from spool top, yoke is riveted together with stage clip again, stage clip is fixed in the knife-edge part of yoke with armature, and armature is free to rotate, forms the magnetic circuit part; Reed is loaded on the base, and the base installing hole is covered and embedding by cover plate.
