Problems solved by technology

[0004] (a) There is no device or function for displaying abnormal states. When the circuit loop is powered off or other abnormal states, the existing power breaker will automatically trip and power off. The user or manager does not know that the power is off, or it is caused The appearance of the power breaker is difficult to distinguish whether it has tripped, and of course it is impossible to eliminate the abnormal circuit in real time and quickly;
[0005] (b), especially in a complex circuit system with more than two or more circuit loops, when one of the circuit loops is tripped or powered off, it is difficult to distinguish the abnormal state of the circuit, increasing the time and difficulty of troubleshooting

Embodiment 2

[0051] The constituent components of embodiment two are the same as those of the foregoing embodiment ( Figure 1 ~ Figure 3 ) are almost the same, the difference is: the side height H of the extension portion 312 ′ of the second contact terminal 31 in the second embodiment is larger than the side height h of the extension portion 312 of the second contact terminal 31 in the embodiment, and the The side height H of the extension portion 312 ′ is greater than the up and down displacement distance of the connecting piece 55 of the indicator light 50 . During the actuation process of the second embodiment, the free end 551 of the connector 55 at the lower end of the second pin 52 of the indicator light 50 and the extension part 312' of the second contact terminal 31 are always in contact with each other, as shown in FIG. Image 6 , Figure 7 shown.

[0052] When implemented, in Image 6 In the normal power-on (ON) state, see also Figure 4A , 4B The current passes through th...

Embodiment 3

[0055] The components of the third embodiment are the same as those of the foregoing embodiments ( Figure 1 ~ Figure 3 ) are almost the same, the difference is: the lower end of the second pin 52' of the indicator light 50 of the third embodiment is fixedly connected and electrically communicated with the second contact terminal 31. In specific implementation, in order not to affect the up and down movement of the button 20 or the indicator light 50, the second pin 52' in the third embodiment is a soft conductive wire body, and the soft conductive wire body is a flexible conductive wire body. Easy to bend material. In this embodiment, the lower end of the second pin 52' is directly welded to the extension portion 312 of the contact terminal 31.

[0056] The operation and principle of the third embodiment are the same as those of the second embodiment above. Regardless of whether the city circuit is in the normal power-on (ON) state or in the power-off (OFF) state when the cu...

Embodiment 4

[0062] Embodiment 4 mainly lies in arranging a third contact terminal 32, so that the circuit loop connected to the indicator light 50 is a current from the first contact terminal 30 to the third contact terminal 32, which is different from the normal current in the general power-on (ON) state from the first contact terminal 32 to the third contact terminal 32. The normal circuit loops from the first contact terminal 30 to the second contact terminal 31 are different. Embodiment 4 is mainly to completely separate the current of the normal circuit loop of power failure and tripping from the current of the indicator light 50 in abnormal state, so as to ensure the safety of electricity consumption, and is more suitable for tripping, power failure or Display of other abnormal states.

[0063] As explained in the above embodiment, in the general normal power-on (ON) state of the present invention, the indicator light 50 is not powered on and does not emit light; Power (OFF) can en...

Abstract

The invention discloses a power disconnecting device capable of displaying abnormal conditions, comprising a box body, a button, at least two contact terminals, a conductive clip and an indicating lamp; wherein the button is arranged in the box body, the button can be penetrated through by light, the indicating lamp is arranged inside the button, the two contact terminals are connected with a circuit loop, the conductive clip deforms when being heated and then bends in a reversed direction, so that a free terminal of the conductive clip bounces towards the other side. In normal power-up state, normal state current of the circuit loop is on, the circuit loop of the indicating lamp is not connected or current thereof levels off to zero, the indicating lamp does not give out light; when current is overloaded or the environment is overheated, the free terminal of the conductive clip trips to disconnect the normal state current of the circuit loop, at the moment, the circuit loop of the indicating lamp is conducted and the indicating lamp gives out light to display the abnormal state of power disconnection.

Description

technical field [0001] The invention relates to an electric device, in particular to a power-off device capable of displaying an abnormal state. Background technique [0002] Existing power breakers usually have an alloy metal sheet composed of two or more metal materials inside. The metal sheet is deformed by overheating. When the current is overloaded and overheated, it can be deformed and automatically turn in the opposite direction. Bounce to cut off the circuit loop to ensure the safety of electricity use. [0003] However, existing power breakers have the following common disadvantages: [0004] (a) There is no device or function for displaying abnormal states. When the circuit loop is powered off or other abnormal states, the existing power breaker will automatically trip and power off. The user or manager does not know that the power is off, or it is caused The appearance of the power breaker is difficult to distinguish whether it has tripped, and of course it is i...
