Abstract
The utility model belongs to the technical field of electric appliance switches, and more specifically, the utility model provides a safety type double-wire switch. The utility model is characterized in that the utility model is provided with a lever connecting wire and a concave body of a switch body which is composed of a pair of inclined gears, wherein, both sides of the concave body are respectively abutted on a driving wheel, the driving wheels are connected with an elastic copper sheets by a turning point of an input binding post, and the two end contacts of the elastic copper sheet are respectively abutted on conductive copper sheets of the input binding post and an output binding post. The utility model has the advantages of high safety, high flexibility, high durability, etc.
Description
The utility model belongs to the appliance switch technical field, particularly is applicable to the circuit appliance switch in the daily life.
In technique known, be installed in the switch in the circuit, or, all be to be serially connected in the effect of opening and closing in the alternating current single line as the switch of electrical appliance.Because the wearing and tearing of thin copper fin, oxidation then forms short circuit easily, and electric leakage or contact resistance such as increase gradually at phenomenon, and the safety effect of switch was lost efficacy.Even cross strong scaling loss electric wire because of transient current sometimes, and damage electrical equipment, also may injure catastrophe failure and accidents such as personal safety, the consequence that is produced is hardly imaginable often.
The purpose of this utility model provides a kind of lever principle of utilizing, and two-wire cuts off circuit fully simultaneously, outside the insulation property of each parts, resets flexibly, makes whole switch reach safety, flexibly, and the safety type two-wire switch of usefulness.
Realize that the scheme that the purpose of this utility model is taked is improved on the basis of original switch, this switch has a lever wiring, the switch body concave body that a pair of inclined gear is formed, the both sides of the concave body driving wheel of having conflicted respectively, driving wheel a little is connected with elastic copper sheet by turning back on the lead-in clamp, two terminal contacts of elastic copper sheet can be respectively with lead-in clamp and output wiring terminal on conductive copper sheet inconsistent.
Because the utility model has been taked above-mentioned technical approach, compared with prior art, it is characterized in that utilizing the action of lever drives helical gear, change the position distance between concave body and driving wheel, reach safe, flexible, durable purpose with the connecting and disconnecting that realize switch.
Utilize accompanying drawing to further describe embodiment of the present utility model below.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, this switch has following element: lever backguy 1, inclined gear 2 (a pair of), reseting groove 3, the identical body 4 of reseting groove, concave body 5, driving wheel 6, lead-in clamp 7, output wiring terminal 8, elastic copper sheet 9 and conductive copper sheet 10, wherein, driving wheel 6 adopts the electro-insulating rubber material.Position as shown is the circuit on-state, when the needs open circuit, draw rod-pulling type backguy 1, the inclined gear that drives in the switch body rotates, and reseting groove 3 is overlapped with the identical body 4 of reseting groove, and related concave body 5 raises, electro-insulating rubber driving wheel 6 is outwards opened, be with elastic copper sheet 9 inwardly to shrink, causing the contact on it to be separated, thereby reach the outage purpose with the conductive copper sheet on the output wiring terminal 8.In the utility model, embodiment can change push type into, only needs the backguy in the lever backguy 1 is removed, and directly presses lever can play on-off action.
The safety type two-wire switch of making by such scheme, have the safety effect that cuts off double-current simultaneously, overcome the deficiency that the single line switch exists, switch starting partly adopts the inclined gear to intersect, reseting performance is good, thus make whole switch totally reach flexibly, safely, purpose such as be difficult for blocking.
Claims (1)
1, a kind of safety type two-wire switch, be characterised in that altogether and have a lever wiring, the switch body concave body that a pair of inclined gear is formed, the both sides of the concave body driving wheel of having conflicted respectively, driving wheel a little is connected with elastic copper sheet by turning back on the lead-in clamp, two terminal contacts of elastic copper sheet can be respectively with lead-in clamp and output wiring terminal on conductive copper sheet inconsistent.
