Abstract
The utility model discloses a kind of safety power switch, comprise: pedestal, be formed at the container cavity in pedestal, be fixed on pedestal and connect the terminal of electric wire, be placed in the button of pedestal indentation, there, be placed in container cavity and be connected in the rotating seesaw coupling assembling of button, corresponding to seesaw coupling assembling and for the connector of connection circuit, be placed in container cavity and control the humidity sensor that seesaw coupling assembling rotates.The utility model provides one can respond to humidity, if humidity exceedes set point, just can automatic shutoff circuit, not only can waterproof avoid short circuit to cause the potential safety hazards such as electric leakage, fire, it is aging that dry part also can delay circuit, increases useful life.
Description
Technical field
A kind of electric equipment, particularly a kind of mains switch.
Background technology
Mains switch of the prior art all can not waterproof, protection against the tide, in infiltrating mains switch, water is easily short-circuited, and electric leakage or breaking out of fire etc., the security performance of mains switch cannot ensure, prior art is unresolved such problem also.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide one can respond to humidity, if humidity exceedes set point, just can automatic shutoff circuit, not only can waterproof avoid short circuit to cause the potential safety hazards such as electric leakage, fire, also can delay circuit aging, increase useful life.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
Safety power switch, comprise: pedestal, be formed at the container cavity in pedestal, be fixed on pedestal and connect the terminal of electric wire, be placed in the button of pedestal indentation, there, be placed in container cavity and be connected in the rotating seesaw coupling assembling of button, corresponding to seesaw coupling assembling and for the connector of connection circuit, be placed in container cavity and control the humidity sensor that seesaw coupling assembling rotates.
Aforesaid safety power switch, seesaw coupling assembling composition has: one end is connected in the spring of button, and the first contact chip of the linking springs other end is placed in the rotating part between spring and the first contact chip.
Aforesaid safety power switch, connector is the second contact chip corresponding to the first contact chip.
Aforesaid safety power switch, rotating part is rotating shaft.
Aforesaid safety power switch, also comprises: be embedded in pedestal and be communicated in the dry part of container cavity.
Aforesaid safety power switch, dry part is silica-gel desiccant.
Aforesaid safety power switch, be fixed on pedestal and connect container cavity and dry part between ventilative web plate.
Usefulness of the present utility model is: the utility model provides one can respond to humidity, if humidity exceedes set point, just can automatic shutoff circuit, not only can waterproof avoid short circuit to cause the potential safety hazards such as electric leakage, fire, it is aging that dry part also can delay circuit, increases useful life.
Brief description of the drawings
Fig. 1 is the sectional view of a kind of embodiment of the present utility model;
The implication of Reference numeral in figure:
1 pedestal, 2 terminals, 3 container cavities, 4 dry parts, 5 buttons, 6 springs, 7 first contacts, 8 the second wafers, 9 humidity sensors, 10 rotating shafts, 11 ventilative web plates.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Safety power switch, comprise: pedestal 1, be formed at the container cavity 3 in pedestal 1, be fixed on pedestal 1 and connect the terminal 2 of electric wire, be placed in the button 5 of pedestal 1 indentation, there, be placed in container cavity 3 and be connected in the rotating seesaw coupling assembling of button 5, corresponding to seesaw coupling assembling and for the connector of connection circuit, be placed in container cavity 3 and control the humidity sensor 9 that seesaw coupling assembling rotates.
Seesaw coupling assembling composition has: one end is connected in the spring 6 of button 5, and the first contact chip of linking springs 6 other ends is placed in the rotating part between spring 6 and the first contact chip.Connector is the second contact chip corresponding to the first contact chip.Preferred as one, rotating part is rotating shaft 10.By stirring dial type button 5, drive the first contact 7 to do contact that " seesaw motion " realize the first contact 7 and the second wafer 8 and separate through spring 6, and then realize the break-make of mains switch; Humidity sensor 9 connects controller, and controller control rotating shaft 10 is rotated, and the first contact 7 and the second wafer 8 of contact are originally separated, thereby circuit is disconnected.
Safety power switch, also comprises: be embedded in pedestal 1 and be communicated in the dry part 4 of container cavity 3; Preferred as one, dry part 4 is silica-gel desiccant; Dry part 4 can absorb the moisture in container cavities 3, makes to keep dry in container cavity 3, thereby slows down the circuit aging speed of making moist; Also comprise: be fixed on pedestal 1 and connect container cavity 3 and dry part 4 between ventilative web plate 11; The design of ventilative web plate 11 makes circulation of air between dry part 4 and container cavity 3.
The utility model provides one can respond to humidity, if humidity exceedes set point, just can automatic shutoff circuit, not only can waterproof avoid short circuit to cause the potential safety hazards such as electric leakage, fire, it is aging that dry part 4 also can delay circuit, increases useful life.
More than show and described general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
