Second fork tongue 32 connects lug plate a41 and lug plate c61, and when control switch 2 is in the open state, third fork tongue 33 is contacted
Connect lug plate b51 and lug plate c61.
2 side of control switch is equipped with cylindrical protrusions 22, is arranged in the cylindrical protrusions 22 and restrains part 23, restrains part
23 peripheries are equipped with connection ring 24, and 1 other side of breaker body is equipped with fixed idler whell 11 and tightener sheave 12, the connecting line 9 one
End is connected and fixed with connection ring 24, and the other end bypasses fixed idler whell 11 and tightener sheave 12, and is connect admittedly with the shaft of motor 8
Fixed, power part 104 is equipped with the ellipse hole 1041 passed through for connecting line 9
The tightener sheave 12 includes fixing seat 121 and the holding part 122 for being equipped with idler wheel 11, and 121 two sides of fixing seat are set
There is the fixed-wing 123 with 1 screw connection of breaker body, 121 bottom of fixing seat is equipped with the ellipse matched with holding part 122
Groove 124.
Specific working principle are as follows:
By axis a13 activity, the first fork tongue 31 passes through axis b21 and control switch for trident tongue connector 3 and breaker body 1
2 are connected and fixed；During control switch 2 opens or closes, the first fork 31 model- following control switch 2 of tongue moves together, makes three
The whole axis rotation around axis a13 of tongue connector 3 is pitched, the position of the second fork tongue 32 and third fork tongue 33 that make changes；
Further, when control switch 2 is in the open state, i.e. the route of breaker connection is powered；At this point, third fork tongue
The contact point 34 of 33 one end touches lug plate b51 and lug plate c61, as shown in Fig. 1, makes power supply 6 and inductor b51 circuit
Connection, inductor b5 transmit a signal to control chip 7, and control chip 7 is made to learn that control switch 2 is in the open state；As at this time
Motor 8 is currently running, then can stop the operation of motor 8；
Further, when control switch 2 is in close state, i.e. the route of breaker connection, which disconnects, to be powered, at this point, second
The contact point 34 of fork 32 one end of tongue touches lug plate a41 and lug plate c61, makes power supply 6 and inductor a41 circuit communication, feels
It answers device a4 to transmit a signal to control chip 7, so that control chip 7 is learnt that control switch 2 is in close state, then start motor 8；
Further, motor 8 rotates, will be around fixed idler whell 11 and action roller 12 and the connection for connecting connection ring 24
The winding of line 9 is got up, and is fulcrum with fixed idler whell 11 and action roller 12, is pulled and is restrained part 23, by matching with containing part 23
Cylindrical protrusions 22 drive control switch 2, keep control switch 2 again in the open state, at this point, 3 turns of trident tongue connector
Dynamic, 33 one end of third fork tongue touches lug plate b51 and lug plate c61 again, makes to control the closing motor 8 of chip 7；
Further, auto-tensioning of the action roller 12 to connecting line 9, when control switch 2 becomes to close from open state
During conjunction state, control switch 2 can make rotating motion around axle center, will drive connection ring 24 in the process of movement, cause
The connecting line 9 being wound on motor 8 is drawn out, have it is certain hang, at this point, being connected by fixed-wing 123 and breaker body 1
Fixed fixing seat 121 plays the role of guide rail, makes the holding part 122 for being equipped with idler wheel along the ellipse of 121 bottom surface of fixing seat
The movement of 124 direction of connected in star that is, between fixing seat 121 and breaker body 1, is connected by the gravity tensioning of holding part 122 itself
Wiring 9 avoids connecting line 9 from being detached from fixed idler whell 11 and action roller 12, and next motor 8 is caused to lose fulcrum when starting
Pull connection ring 24；
Further, the arcuate movement face 106 of contacting part 101 reserves the movable space of trident tongue connector 3, partition 105
To separate the cooperation route of inductor a4 and inductor b5, the two is avoided to pitch tongue 32, the matching of third fork tongue 33 respectively at second
It is interfered when conjunction.
Further, the ellipse hole 1041 on power part 104 limits the motion range of connecting line 9, guarantees connecting line 9
It is wound in the rotary shaft of motor.
By adopting the above-described technical solution, a kind of automatic reset breaker, is connected to inductor by trident tongue connector 3
The route of a4 or inductor b5 make control chip 7 learn that control switch 2 is in the open state or closed state, to control
The starting and closing of motor 8 processed pull control switch 2 to open by connecting line 9, and breaker is made to realize auto-reset function, section
About manpower, effectively avoids the danger that can occur under no illumination condition.
Obviously, above-described embodiment is just for the sake of clearly illustrating done citing, and does not limit the embodiments.
To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
It moves still in the protection scope of the utility model.
