Abstract
The utility model discloses a relay which comprises an iron core, a yoke and an armature. A coil is wound on the iron core. The yoke is used for enhancing the adhesive force of a solenoid. The armature can be combined with the yoke to be a closed magnetic circuit and can move in an axial manner. The cross section area of the iron core is more than one times increased so that the magnetic intensity is enhanced. Therefore, compared with a conventional general power GH-1C-12L type relay, the relay of the utility model is 2\3 of the GH-1C-12L type relay under a condition that the same functions are provided, thereby reducing the amount of enamelled wires and terminal copper material, and reducing the cost of material.
Description
Technical field
The utility model relates to the electric control device, particularly a kind of relay.
Background technology
Relay is a kind of electric control device.It has the interactive relationship between control system (claim not only input circuit) and the Be Controlled system (but also claiming output loop).Usually be applied in the control circuit of automation, it is actually a kind of " automatic switch " that goes to control big electric current running with little electric current.So in circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit, electromagnetic relay generally is made up of iron core, coil, armature, contact reed etc.As long as add certain voltage at the coil two ends; Will flow through certain electric current in the coil; Thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of electromagnetic attracting force inhales to iron core, thereby drives the moving contact and fixed contact (normally opened contact) adhesive of armature.Behind coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return original position at the reaction force of spring, and moving contact and original fixed contact (normally-closed contact) are discharged.Adhesive like this, release, thus reached the conducting in circuit, the purpose of cut-out.Relay generally has two strands of circuit, is low-voltage control circuit and high-pressure work circuit.But the cost of existing relay is higher relatively.
The utility model content
The utility model technical problem to be solved is: the coil consumption of relay is reduced, terminal copper material consumption reduces and save cost, and a kind of relay cheaply is provided.
The utility model proposes a kind of relay, comprise around by the iron core of coil, strengthen the yoke of solenoid the suction-combining force and can form closed magnetic circuit with said yoke and also can make axially movable armature, the cross-sectional area of said iron core increase be twice above.
Preferably, the cross-sectional area of said yoke increase be twice above.
Preferably, the cross-sectional area of contact area between said armature and the said yoke and said yoke is big or small identical and adaptive.
Preferably, the coil of said iron core reduces more than 1/3.
The cross-sectional area of the utility model iron core increase be twice above; The cross-sectional area of said yoke also increase be twice above; With existing universal power relay GH-1C-12L contrast, under the prerequisite that does not influence its identical function, the relay of the utility model only is 2/3 of GH-1C-12L; Reduce the consumption of enamelled wire and terminal copper material, on material, reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model relay one embodiment.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1, an embodiment of the relay of the utility model is proposed, this relay comprises has skeleton 1, shell 2, iron core 3; Armature 4, reed 5, yoke 6 and enamelled wire 7 are wound with coil on the iron core 3; Coil, iron core 3, armature 4, yoke 6 has constituted a magnetic circuit system with reed 5; Because this relay has in height been done change; Be 2/3 of existing universal power relay GH-1C-12L model relay only; Skeleton 1 window will dwindle accordingly like this, causes diminishing of magnetic intensity, in order not influence the function of use of this relay; Need to strengthen magnetic intensity, strengthen the suction-combining force of solenoid; In order to strengthen the solenoid the suction-combining force, said cross-sectional area around the iron core 3 that coil is arranged increases and is twice abovely, and the cross-sectional area of said yoke 6 also increases and is twice abovely, and to reduce the consumption of coil, coil reduces more than 1/3; Can form closed magnetic circuits with said yoke 6 and can do cross-sectional area big or small identical and adaptive of contact area and said yoke 6 between axially movable armature 4 and the said yoke 6; The relay of the utility model has reduced the consumption of enamelled wire and terminal copper material, on material, has reduced cost.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
Claims (4)
1. a relay is characterized in that, comprise around by the iron core of coil, strengthen the yoke of solenoid the suction-combining force and can form closed magnetic circuit with said yoke and also can make axially movable armature, the cross-sectional area of said iron core increase be twice above.
2. relay according to claim 1 is characterized in that, the cross-sectional area of said yoke increase be twice above.
3. relay according to claim 2 is characterized in that, the contact area between said armature and the said yoke and the cross-sectional area of said yoke big or small identical and adaptive.
4. according to each described relay in the claim 1 to 3, it is characterized in that the coil of said iron core reduces more than 1/3.
