Description
Technical field
The utility model belongs to adaptive polarizing memory voltage time constant field, and in particular to a kind of relay of the anti-contact splash structure of band.
Background technology
Relay is a kind of electric control device.It has control system (also known as input circuit) and (is also known as by control system
Output loop) between interactive relationship.In the control circuit for being commonly used to automation, it is actually that control is gone with low current
One kind " automatic switch " of high current running.Therefore play in circuit automatically adjust, safeguard protection, the effect such as change-over circuit, electricity
What magnetic relay was typically made up of iron core, coil, armature, contact reed etc..As long as adding certain voltage, line at coil two ends
Certain electric current is will pass through in circle, so as to produce galvanomagnetic-effect, armature will overcome return in the presence of electromagnetic attracting force
The pulling force of spring is drawn to iron core, so that the movable contact with moving armature and stationary contact (normally opened contact) adhesive.After coil blackout, electricity
The suction of magnetic also disappears therewith, and armature will return to original position in the reaction force of spring, make movable contact and originally quiet
Contact (normally-closed contact) discharges.So adhesive, release, so as to reach conducting in circuit, the purpose of cut-out.
Relay contact during electric life is influenceed moment to reach silver point by temperature rise, is touched under the impact of mechanical movement
Point coating produces silver particles to around splashing, and (iron core and stationary contact) sets up " electric bridge " between load disconnecting circuit, makes load
Creep age distance between disconnecting circuit shortens, after certain electric life cycle, when dielectric withstanding voltage is equal to or less than load voltage, bears
Persistence drag arc produces high temperature in the presence of electric current between load disconnecting circuit, makes contacts welding caused by the overheat of contact.Cause contact
Rupture capacity, which declines, causes contact adhesion to fail, or core insulation punctures and causes relay to damage caused by climbing electricity.
Utility model content
The utility model is in order to solve above-mentioned problems of the prior art, and it is anti-tactile that the utility model provides a kind of band
The relay of point splash structure, can effectively stop that silver particles are splashed, it is to avoid arcing, improve relay life.
The utility model use concrete technical scheme be：
A kind of relay of the anti-contact splash structure of band, including shell and the skeleton that is arranged in shell, described bone
Set to be provided with movable contact, skeleton on cored, armature, armature on frame and be provided with stationary contact, armature is hinged to be formed with skeleton
The free degree is swung, movable contact is engaged by armature with stationary contact formation, and barricade plate, barricade plate are had additional on described skeleton
It is horizontally installed between stationary contact and iron core, described barricade plate is hollow platy structure.
Described barricade plate includes the work department being separately positioned between the connecting portion at two ends and connecting portion, described connection
Portion horizontal cross-section shape in a rectangular trapezoid, work department is arranged at the right angle stringcourse of both sides connecting portion, and work department is highly less than connection
Portion's height.
The hollow cavity width of described barricade plate is not more than 1/3rd of barricade plate thickness.
Along the curved structure of vertical section in described work department.
The beneficial effects of the utility model are：
The utility model, by the way of barricade plate is set up, splash is stopped, when adding disconnecting circuit climb electricity away from
From, be conducive to preventing arcing from producing, stop splash conducting bridge is formed between contact and iron core, it is ensured that the safety of iron core makes
With preventing core insulation from puncturing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of skeleton part；
In accompanying drawing, 1, skeleton, 2, iron core, 3, armature, 4, movable contact, 5, stationary contact, 6, barricade plate, 7, connecting portion, 8, work
Make portion.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail：
The utility model is a kind of relay of the anti-contact splash structure of band, including shell and the bone that is arranged in shell
Set to be provided with movable contact 4, skeleton 1 on cored 2, armature 3, armature 3 on frame 1, described skeleton 1 and be provided with stationary contact 5,
Armature 3 is hinged to form the swing free degree with skeleton 1, and movable contact 4 is engaged by armature 3 with the formation of stationary contact 5, described bone
Barricade plate 6 is had additional on frame 1, barricade plate 6 is horizontally installed between stationary contact 5 and iron core 2, described barricade plate 6 is hollow
Platy structure.
Described barricade plate 6 includes the work department 8 being separately positioned between the connecting portion 7 at two ends and connecting portion 7, described
The horizontal cross-section of connecting portion 7 shape in a rectangular trapezoid, work department 8 is arranged at the right angle stringcourse of both sides connecting portion 7, the height of work department 8
Less than the height of connecting portion 7, the described width of work department 8 is more than the width of connection sheet between movable contact and armature 3, and work department 8 is high
When degree is less than the dynamic and static closing of contact, the distance between connection sheet and iron core upper surface.
The hollow cavity width of described barricade plate 6 is not more than 1/3rd of the thickness of barricade plate 6, advantageously ensures that gear
The both sides intensity of wallboard 6 and the effect transmitted by cavity blocking temperature.
Along the curved structure of vertical section in described work department 8, work department hardness is reduced whereby, and softening contacts effect,
Mutually damage is produced when avoiding connection sheet because of inertial impaction work department 8.
As shown in Figures 1 and 2, the utility model is additionally arranged barricade plate 6 to specific embodiment, in the case where armature 3 is attracted by iron core 2
During shifting, sound contact is collided to the splash produced and stopped, it is ensured that preferably isolates and insulate, be arranged on the sky in barricade plate 6
Chamber, helps to reduce deflection when barricade plate 6 is hit by air-flow and splash, improves reliability, and cavity can hinder
Keep off heat transfer, it is to avoid the high temperature of splash causes the overall temperature rise and deformation of barricade plate 6.
