Abstract
The utility model discloses a high anti-vibration electromagnetic relay which comprises a contact system, a bracket, an electromagnetic system, an anti-vibration plate and a shell. The clearance between the electromagnetic system and the internal side of the shell is provided with the anti-vibration plate made of flexible material. The anti-vibration plate is pressed into the clearance between the electromagnetic system and the internal side of the shell; the central platform on the anti-vibration plate is fixed on a yoke of the electromagnetic system through spot welding; the size of the anti-vibration plate is larger than the clearance between the electromagnetic system and the internal side of the shell so as to flexibly deform the anti-vibration plate; the two ends of the anti-vibration plate flexibly contact the internal side of the shell respectively so as to further enhance the anti-vibration performance of the overall relay.
Description
One, technical field
The utility model relates to a kind of relay, relates in particular to a kind of high antivibration electromagnetic relay.
Two, background technology
The effect of electromagnetic relay is circuit switched and signal transmission.Generally, electromagnetic relay is in the influence of transporting and length of life is all vibrated, under the effect of extraneous exciting force, electromagnetic system that it is inner and contact system will produce vibration along with the motion of relay, cause closing contact to disconnect voluntarily, or make break contact closed voluntarily, influence reliability of products.
The electromagnetism relay that continues comprises outer cover, contact system, electromagnetic system and is configured to.Do not have between the electromagnetic system of existing electromagnetic relay and the outer cover and directly contact, be connected with contact system formation by support, formation with between contact system and the outer cover be welded as fixing point, be the cantilever beam structure that beam, center of gravity (electromagnetic system) are positioned at the cantilever end with the support, make the antivibration ability of electromagnetic relay low.
Two, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high antivibration electromagnetic relay is provided.
High antivibration electromagnetic relay of the present utility model, it is made up of contact system, support, electromagnetic system, antivibration sheet and outer cover, the antivibration sheet is in the gap that is fixed between electromagnetic system and the outer cover inboard, wherein antivibration sheet halfpace part is fixed on the yoke of electromagnetic system by spot welding, two ends of antivibration sheet and outer cover Elastic Contact, the antivibration sheet is an elastomeric material.
Adopting the beneficial effect of technique scheme is to improve the contact system resistance to shock effectively, has retrained the resonance of electromagnetic mechanism effectively, has improved the vibration resistance of electromagnetic mechanism, has improved the relay resistance to shock effectively.
Four, description of drawings
Fig. 1 is the structural representation of the high antivibration electromagnetic relay of the utility model.
Among the figure: 1-contact system, 2-support, 3-electromagnetic system, 4-antivibration sheet, 5-outer cover 6-yoke.
Fig. 2 is the structural representation of the antivibration sheet of the high antivibration electromagnetic relay of the utility model.
Among the figure: 4a-antivibration sheet end, 4b-antivibration sheet end, 4c-antivibration sheet halfpace.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
High antivibration electromagnetic relay of the present utility model, it is made up of contact system 1, support 2, electromagnetic system 3, antivibration sheet 4, outer cover 5, and as shown in Figure 1, antivibration sheet 4 is pressed in the gap between electromagnetic system 3 and outer cover 5 inboards.As shown in Figure 2, antivibration sheet 4 is made up of antivibration sheet two end 4a, 4b and antivibration sheet halfpace 4c, wherein antivibration sheet halfpace 4c point is welded on the yoke 6 of electromagnetic system, because the size of antivibration sheet 4 is big than the gap between electromagnetic system 3 and the outer cover 5, make antivibration sheet 4 that strain take place, its two end 4a, 4b just form Elastic Contact with the inboard of outer cover 5 respectively, the reaction force that this strain produces directly acts on electromagnetic system 3, reaches the purpose of the resistance to shock that improves the relay complete machine.
