1065。
By using technique scheme, the setting of arc extinction part 6 and arc extinguishing inserted sheet 91 can be to moving contact 2 when action
Produce electric arc play inhibitory action, striking catch 8 between arc extinguishing face 61 and silver contact 21, due to arc extinguishing face 61 in curved
Folding is arranged, and therefore the electric arc produced during silver contact 21 switching action is served guiding function, and electric arc is served stop
Effect, the generation of arc phenomenon is climbed in suppression.Cooperation arc extinction part 6 own material properties that arranges of folding line 81 enables to striking catch
8 have the good effect that automatically resets.Arc extinction part 6 and moving contact 2 are coaxially fixed, and it is firm more to stablize, and meanwhile, are assembling
During dismounting the most convenient.Moving contact 2 is fixed on contact rack 1 with coordinating of fixing axle 7 by sidewall 11, assembles simple and convenient
Fast, time saving and energy saving, and fixed effect stablize firm.The setting of metal reinforced part 9 can be to contact rack 1 and moving contact 2
The overall structure constituted plays good reinforcement effect.The both sides of moving contact 2 can abut with both sides sidewall 11 respectively, and this is right
Sidewall 11 can play the effect of clamping moving contact 2.
Propelling piece 105 uses V-arrangement shell fragment and is positioned between static contact 104 and moving contact 2, the one of propelling piece 105
End abuts with moving contact 2, and the other end abuts with the inwall of the pedestal 101 at static contact 104 place, it is possible to propelling piece 105 is had
Have and strut static contact 104 and the active force of moving contact 2, hence in so that moving contact 2 is more quickly and effectively away from stationary contact during disjunction
104 so that breaking speed is promoted.The setting of propelling piece 105 can be accelerated moving contact 2 and separate speed with static contact 104
Degree, when moving contact 2 is during static contact 104 moves until abutting, the active force of propelling piece 105 savings is also increasing, directly
Abut with static contact 104 to moving contact 2, this active force to peaking, there is certain potential energy, thus reach moving contact 2 and dividing
The when of disconnected, speed has been accelerated；Pre-fixing groove 1066 makes pedestal 101 be connected more with upper cover 102 with the setting of fixing raised line
Stable firm.The setting of screwed hole 1063 and tool insert hole 1064 makes pedestal 101 and upper cover 102 connect more stable jail
Lean on.
Owing to its volume of frame body 10 in open frame circuit breaker is relatively big, heavier-weight, it has not been convenient to operator take
Handling, therefore the setting of grip part 103 makes the operator can be convenient taking frame body 10 when, it is simple to execute
Power.Grip part 103 is arranged to groove simpler, convenient, fast.The degree of depth of grip part 103 is at least 5mm, and width is extremely
Drawing through applicant's test of many times for 15mm less so that user is more convenient when touching to be held, force more conforms to people office
System.The electric arc that moving contact 2 produces when action can be played inhibitory action by arc extinction part 6, the setting of arc extinguishing inserted sheet 91, and striking keeps off
Sheet 8 is between arc extinguishing face 61 and silver contact 21, owing to arranging in bending, therefore to silver contact 21 switching action with arc extinguishing face 61
Time the electric arc that produces serve guiding function, and electric arc is served the effect of stop, the generation of arc phenomenon is climbed in suppression.
Owing to silver contact 21 produced electric arc when action has certain impact dynamics, striking catch 8 can be released to,
Cooperation arc extinction part 6 own material properties that arranges of folding line 81 enables to striking catch 8 and has the good effect that automatically resets.Go out
The electric arc that moving contact 2 produces when action can be played inhibitory action by the setting of arc inserted sheet 91.The setting of connector 106 makes
Pedestal 101 is connected with upper cover 102 more closely, firmly.Axle sleeve 1061 end face different from inserts 1062 can give full play to several
What figure is the feature of structure so that upper cover 102 and pedestal 101 connect effect and strengthen further.
The structure that contact rack 1 and moving contact 2 entirety are constituted can be played good adding by the setting of metal reinforced part 9
Gu effect.The both sides of moving contact 2 can abut with both sides sidewall 11 respectively, and sidewall 11 can be played clamping moving contact 2 by this
Effect.Locking piece 73 and latch recess 721 can lock the axial length of fixing axle 7.Clamping salient point 732 and latch recess 721
Snap-fit engagement produce axial spacing so that moving contact 2 is securely fastened on the sidewall 11 of contact rack 1.Fixed groove and
The setting reinforcing male member makes spring 3 have a dual fixing guarantee at moving contact 2 and contact rack 1, the outer surface at spring 3 two ends with
Fixed groove clamping, reinforces male member and inserts spring 3, the center of spring 3 being played fixation, so can be greatly improved dynamic
Contact 2, when divide-shut brake duty switches, is greatly improved the stability of spring 3.The setting of chamfered section 722 enables to operation
Personnel are more prone to fixing axle 7 through through hole.Chamfered section 722 more convenient installation is set.
