Description
Technical field:
The utility model relates to line protective device technical field, is specifically related to a kind of novel overcurrent protection switch.
Background technology:
In electric wiring, permission, continuously by the magnitude of current that is unlikely to make electric wire overheated, is called safe carrying capacity or safe current.The electric current flowing through as wire has surpassed safe carrying capacity, is just wire overloading.The general the highest permission working temperature of wire is 65 ℃.During overload, temperature surpasses this temperature, can make the rapidly aging burning of circuit even of insulation.In machinery, when axle surpasses the load can bear, overload protection can prevent overload and the apparatus that causes damages.
Illuminating line in building, likely causes the power line of wire or cable long term overloading, and adopts and have when prolonging the insulated conductor that burns sheath and being laid on flammable or difficult burning building element, all should take overload protection.The overload protection of circuit should adopt automatic switch.During operation, automatic switch long delay action tuning current should not be greater than circuit and allow for a long time load current.
But current automatic switch contact performance is poor, cause stability, electric conductivity all poor, good protection can not be provided in circuit overload.
Utility model content:
The purpose of this utility model is to provide a kind of novel overcurrent protection switch, and its design science is reasonable, can better contact, and increases stability, better conduction.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises button 1, switch housing 2, indicator light 3, power spring 4, L level binding post 5, N level binding post 6, E level binding post 7, fixed contact 8, armature contact 9, metal clips 10, connecting rod 11, shell buckle 12 and shell baffle plate 13, the rear end of switch housing 2 is provided with shell baffle plate 13, the bilateral symmetry of switch housing 2 is provided with shell buckle 12, the upper end of switch housing 2 is provided with button 1, button 1 lower end is connected with metal clips 10 by connecting rod 11, armature contact 9 is riveted on the little shell fragment of metal clips 10 intermediate projections, armature contact 9 lower end correspondences are provided with fixed contact 8, the lower end of switch housing 2 is provided with L level binding post 5, N level binding post 6, E level binding post 7, fixed contact 8 is connected with E level binding post 7, L level binding post 5, N level binding post 6 is all connected with the indicator light 3 of button 1 lower end by power spring 4.
Principle of the present utility model is: button 1 is connected with connecting rod 11, connecting rod 11 is connected with metal clips 10 again, armature contact 9 is riveted on the little shell fragment of metal clips 10 intermediate projections, off-state, press the button at 1 o'clock, connecting rod 11 drives metal clips 10, makes armature contact 9 and fixed contact 8 in closure state, energising.When power supply transships, metal clips 10 heatings, utilize principle of expanding with heat and contracting with cold, and metal clips 10 flicks, and armature contact 9 and fixed contact 8 is separated, power-off.In this process, metal clips 10 drives connecting rod 11, and button 1 is resetted.
Utilizing power spring 4 connection indicator lights 3 and L level binding post 5, N level binding post 6, is in order can better to contact, and increases stability, better conduction.
The utility model design science is reasonable, can better contact, and increases stability, better conduction.
