Abstract
The utility model relates to an electric locked switch. The electric locked switch is composed of a switch body, a rotating device controlled by a key, and a switch terminal used to connect input and output conducting wires. The axis of the rotating device is provided with an insulator. The insulator can rotate to switch on or switch off power supply. The electric locked switch suggested by the utility model has the advantages of safe and easy use, low cost, and easy manufacture. The electric locked switch plays effective control action for minors to use electric apparatus.
Description
The utility model relates to a kind of electrolock fixed pattern switch.
Electric switch is control power turn-on and the fexible unit of closing, and range of application is extremely extensive.And the electric switch that generally adopts at present mainly contains button and stay-supported, this type of switch uses easily, as long as press button or spur backguy and get final product conducting or powered-down, but this shirtsleeve operation is really powerless concerning restriction minor or other should not make the people of electrical appliance, sees TV or uses other household electrical appliance etc. such as the control student.
In order to reach effective control to electric use, a kind of electrolock fixed pattern switch has as shown in Figure 3 appearred on the market, this switch has a body 1, front end at body 1 is provided with two switch terminals 2, by the tumbler 4 of key 3 control, and the metallic laminas 5 that is provided with at the front end of tumbler 4.During use, rotate tumblers 4, when forwarding metallic laminas 5 to and join, get final product turn-on power with switch terminal 2 by key 3; When forwarding sheet metal 5 to and do not join, get final product powered-down with switch terminal 2.Taking off key can lock previous status.But contact for a long time between the sheet metal 5 of this kind switch and the switch terminal 2 can the generation spark, the material of electric arc or dust, particulate, deposit and so on, and in addition, the plug that household electrical appliance are drawn can not directly join, and it is not too convenient to use.
The purpose of this utility model be design a kind of by key control, can directly be applied in the electrolock fixed pattern switch on power lead or the attaching plug.
Electrolock fixed pattern switch provided by the utility model, be by the electric switch body, with the tumbler of key control, and the switch terminal that is used to connect the input and output lead constitutes, and be provided with an insulator on the axle of tumbler, the rotation of this insulator can disconnect or closed two switch terminals.For the overlapping ends that guarantees switch terminal be not subjected to external force to do the time spent can tight closure, be provided with a spring in the bottom of the switch terminal overlapping ends that connects the input and output lead.Tumbler is constituted by key and by the axle that key is controlled, this goes up the insulation consideration that is provided with and is placed on the switch terminal that joins with spring, the insulator that is provided with on this is a cuboid, half Cylinder or triangular prism, and this insulator is vertical mutually with switch terminal.For the attaching plug that makes former electrical equipment can directly be used on this switch, be provided with two grooves at an end of Switch main body, each groove is provided with a securing member.
The utility model proposes a kind of electric switch with key control, this switch adopts the closure of a rotatable insulator control power supply, and is not only esy to use, safe and reliable, and cost is low, and easily processing makes electrical appliance play control action to the minor.
The cross-sectional view of an embodiment of accompanying drawing 1 the utility model
Accompanying drawing 2 is cross-sectional view of another embodiment of the utility model
Accompanying drawing 3 is cross-sectional view of prior art
The utility model is described in further detail below in conjunction with embodiment.
As shown in Figure 1, there is shown the electrolock fixed pattern switch of an embodiment of the utility model, the body external form of switch is like attaching plug, and by base plate (1) and the similar loam cake formation of base plate therewith, loam cake is closed bottom (1) from top to bottom.A tumbler (3) is fixed in a side of base plate (1), is provided with a rotation axis (2) in this tumbler.Rotation axis (2) one ends are arranged in the tumbler (3), and are complementary with key (8), and the other end is put into the axis hole (9) of base plate (1) opposite side.Key (8) inserted tumbler (3) and rotate this key (8) and can drive rotation axis (2) and rotate.Fix an insulation board (4) on rotation axis (2), this insulation board can be designed to longitudinal bodies, half Cylinder or triangular prism, and its meaning is when rotating insulation board (4) switch terminal (5) is moved down.
An entrance hole (10) and an exit of electric wire (12) are arranged in the base plate (1), exit (12) can be directly and power lead join, also can be designed to sheet metal (11) form among the figure, it is to make this switch application in attaching plug that present embodiment adopts this kind design.
Lead (6) in the entrance hole among the figure (10) joins with switch terminals (5).Another lead and sheet metal (11) join.Switch terminal (5) one ends are unsettled to be fixed on the base plate (1), promptly leaves certain space between switch terminal (5) and the base plate (1).The sheet metal (11) of switch terminal (5a) end and exit joins, and the other end freely is placed on the top of switch terminal (S).A spring (7) is equipped with in the bottom of the free end (5b) of switch terminal (5), and this spring (7) is given power that makes progress of free end (5b) of switch terminal (5), so that the overlapping ends of two switch terminals can fluid-tight engagement under the effect that is not subjected to external force.
Insulator in the present embodiment (4) is arranged to longitudinal bodies, two faces that longitudinal bodies is adjacent are unequal, when insulator (4) rotates, give the downward power of free end (5b) of switch terminal (5), so that the overlapping ends of two switch terminals disconnects, this moment, switch was in closed condition.The rotation of insulator (4) must be controlled by key (8), to reach the purpose of this utility model.
Accompanying drawing 2 has provided another embodiment of the present utility model, its design principle and the foregoing description are basic identical, just the end at body (1) is provided with two grooves (101), one end of this groove respectively is provided with a screw (102), the sheet metal (104) of the attaching plug of electrical equipment (103) can directly insert in the groove (101), at this moment, screw (102) is advanced, and insert in the hole (105) of sheet metal (104), as the loam cake of not opening body (1) screw (102) is extracted, attaching plug (103) is fixed in the body (1).Present embodiment provides a kind of method of this switch and appliances power source plug being united use, so that existing attaching plug also can directly be used the locking of this switch.
