Embodiment
Providing the detailed introduction of a kind of switch of the utility model below in conjunction with accompanying drawing, but should be pointed out that embodiment of the present utility model is the preferred embodiment for task of explanation, is not the restriction to the utility model scope.
Referring to accompanying drawing 1, the structural representation of a kind of switch one embodiment of the utility model, described switch comprise a switch element 11 and are integrated in device for under-voltage releasing equipment 12, armature 13, the first elastomeric element 14, lever 15 and the second elastomeric element 16 in same box body (not shown) with described switch element 11.
Described switch element 11 is connected with the master switch 19 of outside and outside electrical equipment (electric light 18 as shown in the figure) respectively, after master switch 19 closures, can or disconnect by the closed of switch element 11, controls the opening and closing of electric light 18.Wherein, switch element described in the present embodiment 11 is push switch.
Described device for under-voltage releasing equipment 12 is arranged between outside master switch 19 and described switch element 11; An electric wire part that namely is connected between outside master switch 19 and described switch element 11 is wrapped in described device for under-voltage releasing equipment 12.When the circuit of described switch element 11, master switch 19, electric light 18 and external power source 17 compositions is path, described device for under-voltage releasing equipment 12 can produce the described armature 13 that the suction-combining force attraction is attached thereto, and above-mentioned circuit is when opening circuit, and described device for under-voltage releasing equipment 12 the suction-combining forces disappear.
Described armature 13 1 ends are flexibly connected with described device for under-voltage releasing equipment 12 with passing through connecting axle 131, and the other end is connected on described lever 15; Described armature 13 is made for metal material.
Described the first elastomeric element 14 1 ends are fixedly connected with described armature 13, and the other end is fixed in described box body; Be that the first elastomeric element 14 that described armature 13 is fixed in described box body is hung up.Described the first elastomeric element 14 can be spring.
During 12 energising of described device for under-voltage releasing equipment to the suction-combining force of described armature 13 pulling force greater than 14 pairs of described armature 13 of described the first elastomeric element, described armature 13 is attracted and described lever 15 is not produced pressure by described device for under-voltage releasing equipment 12 when power on circuitry like this, and described armature 13 is pushed described lever 15 by described the first elastomeric element 14 pull-ups when down circuitry.
Described the second elastomeric element 16 1 ends are fixedly connected with described lever 15, the described switch element 11 of other end butt.When described armature 13 extrusion lever 15, can drive described the second elastomeric element 16 and push described switch element 11 open like this, make described switch element 11 recover off-state.Described the second elastomeric element 16 can be spring.
Referring to accompanying drawing 2, the structural representation of a kind of another embodiment of switch of the utility model, different from last embodiment is that in the present embodiment, switch element 11 adopts stay wire type switch.Described stay wire type switch comprises the first sheet metal 21, be arranged on a plurality of the second sheet metals 22 on the ratchet of stay wire type switch and the bracing wire 23 of drawing from ratchet, good in order to ensure contact, when the first sheet metal 21 contacts with the second sheet metal 22, have a bit of overlapping between the two.Adopt 6 the second sheet metals 22 to be evenly distributed on ratchet in the present embodiment.Wherein, the first sheet metal 21 and a plurality of the second sheet metal 22 all can adopt copper sheet.
Described the first sheet metal 21 be fixed in circuit and butt to described the second elastomeric element 16.Device for under-voltage releasing equipment 12 is arranged between the ratchet of master switch 19 and stay wire type switch, is connected with master switch 19 through electric wire one end in described device for under-voltage releasing equipment 12, and the other end is connected with respectively second sheet metal 22 on being arranged on ratchet.
When described master switch 19 was closed, when pulling bracing wire 23 1 times, wherein second sheet metal 22 was near the first sheet metal 21, but both do not contact; Again pull bracing wire 23 to make above-mentioned the second sheet metal 22 contact with the first sheet metal 21, power on circuitry, armature 13 is attracted by device for under-voltage releasing equipment 12, and lever 15 is kept normal condition.After master switch 19 disconnected, device for under-voltage releasing equipment 12 dead electricity discharged 13, the first 14 moments of elastomeric element of armature with armature 13 pull-ups; Thereby armature 13 extrusion levers 15 make the second elastomeric element 16 push the first sheet metal 21 open; The first sheet metal 21 separates with the second sheet metal 22, and stay wire type switch recovers off-state.
The occupation mode of a kind of switch of the utility model is:
1. when have electricity night, when indoor have people's Closing Switch element 11(push type or stay wire type switch all can), power on circuitry, armature 13 is attracted by device for under-voltage releasing equipment 12, lever 15 is kept normal condition, electric light 18 normal operation.
2. when when outage, device for under-voltage releasing equipment 12 dead electricity discharge 13, the first 14 moments of elastomeric element of armature with armature 13 pull-ups; Thereby armature 13 extrusion levers 15 make the second elastomeric element 16 push switch element 11 open, make switch element 11 recover off-state.
3. when switching on morning, because switch element 11 disconnects, can't light electric light 18; Only have when people's Closing Switch element 11 is arranged, electric light 18 just can be reworked.Then repeat the work of front.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
