Abstract
The utility model discloses a relay, which comprises a pedestal, a main rack, an iron core, a movable spring sheet, a yoke and an armature, wherein a coil is wound on the external surface of the iron core, the yoke, the armature and the iron core wound with the coil form a closed magnetic circuit, a wiring sheet penetrates through the pedestal, woven leads are connected to the movable spring sheet, and connected to the wiring sheet. When in use, interference among the three woven leads can be prevented through arranged projection blocks, the armature can overcome pulling force of the spring through an electromagnetic effect generated through coil electrifying so as to drive attracting of a movable contact and a stationary contact of the armature, when the coil powers off, the armature returns to an original position, and the movable contact and the stationary contact enable release, such that attracting and release are performed, and purposes of conduction and cut-off in the circuit are achieved. The relay has the beneficial effects of simple structure, convenient usage and installation, simple operation, safety, reliability, good overpressure resistant effect, wide scope, large magnetic strength and low cost.
Description
Technical field
The utility model relates to a kind of relay.
Background technology
Relay is a kind of electric control device, it has control system and by the interactive relationship between the control system, usually be applied in the control circuit of automation, he is actually a kind of automatic switch that goes to control big electric current running with little electric current, and its magnetic intensity of existing relay is big inadequately, and meeting phase mutual interference between the braided wire, this all brings inconvenience to the user.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model provides a kind of relay, compare with existing relay, difference is by set projection, can place the mutual interference of three braided wires, the galvanomagnetic effect that produces by coil electricity, the pulling force that makes armature overcome spring is inhaled to iron core, drive the dynamic and static contact adhesive of armature, behind coil blackout, armature is got back to original position, moving contact and original fixed contact are discharged, adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.
(2) technical scheme
For addressing the above problem, the utility model adopts following technical scheme:
A kind of relay, comprise base, body frame, iron core, movable contact spring, yoke and armature, described body frame is installed on the base, described body frame external seal fixedly has shell, described core exterior surface is wound with coil, described yoke and armature and twine the iron core of being full of coil and form a closed magnetic circuit, described armature links to each other with yoke, the cross-sectional area of described armature and yoke junction is identical with the cross-sectional area of yoke, be penetrated with the line sheet on the described base, described movable contact spring is connected with braided wire, and described braided wire links to each other with lug plate.
As optimized technical scheme, described braided wire is provided with three, and described enclosure is provided with the projection of isolating adjacent braided wire, and described projection is provided with two.
As optimized technical scheme, the cross-sectional area of described iron core increase be twice above.
As optimized technical scheme, the coil on the described iron core reduces more than 1/4th.
As optimized technical scheme, the cross-sectional area of described yoke increase be twice above.
(3) beneficial effect
The utility model is compared to prior art, has following beneficial effect: 1. and simple in structure, use, easy for installation, simple to operate, safe and reliable; Withstand voltage effective, scope is wide, magnetic intensity is big, cost is low.
Description of drawings
Fig. 1 is the structural representation of a kind of relay of the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of relay of the present utility model, comprise base 1, body frame 2, iron core 4, movable contact spring 5, yoke 7 and armature 8, described body frame 2 is installed on the base 1, described body frame 2 external seals fixedly have shell 3, described iron core 4 outer surfaces are wound with coil 6, described yoke 7 and armature 8 with twine the iron core 4 of being full of coil 6 and form a closed magnetic circuit, described armature 8 links to each other with yoke 7, the cross-sectional area of described armature 8 and yoke 7 junctions is identical with the cross-sectional area of yoke 7, be penetrated with line sheet 9 on the described base 1, described movable contact spring 5 is connected with braided wire 10, and described braided wire 10 links to each other with lug plate 9.
Described braided wire 10 is provided with three, and described shell 3 inside are provided with the projection 11 of isolating adjacent braided wire 10, and described projection 11 is provided with two, by set projection 11, can effectively solve the phase mutual interference of 10 of braided wires.
The cross-sectional area of described iron core 4 increases and is twice abovely, and in this enforcement example, the cross-sectional area of described iron core 4 increases twice than the cross-sectional area of common iron core.
The cross-sectional area of described yoke 7 increases and is twice abovely, and in this enforcement example, the cross-sectional area of described yoke 7 increases twice.
Add certain voltage at coil 6 two ends, will flow through certain electric current in the coil 6, thereby generation galvanomagnetic effect, armature 8 will overcome the pulling force of return spring and inhale to iron core 4 under the effect of electromagnetic attracting force, thereby drive moving contact and the fixed contact adhesive of armature 8, after coil 6 outages, the suction of electromagnetism also disappears thereupon, armature 8 will return original position at the reaction force of spring, moving contact and original fixed contact are discharged, adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.
The beneficial effects of the utility model have: 1. and simple in structure, use, easy for installation, simple to operate, safe and reliable; Withstand voltage effective, scope is wide, magnetic intensity is big, cost is low.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
