Description
Technical field
The utility model is related to a kind of miniature circuit breaker, specifically, be related in a kind of miniature circuit breaker it is manual with
It is automatically brought into operation transition components.
Background technology
Miniature circuit breaker is most popular a kind of terminal protection electrical equipment during building electrical terminal power distribution equipment is drawn.It is miniature
Breaker is made up of close/open machine, contact portion, protection device, arc quenching system etc..Its operation principle is：Utilize protection device
(electrical apparatus release) and electrical current heat component realize overload and short-circuit protection, when the electric current that the coil in electrical current heat component passes through is more than setting
Current value when, magnetictrip dynamic iron core action, promote strike bar hit operating mechanism, unlock operating mechanism, make to break
Road device separating brake and then disconnecting circuit, so as to realize overload and short-circuit protection to circuit.After fault is discharged, then by dividing
Switching-on mechanism carries out closing operation so as to connect circuit.At present, most miniature circuit breakers that China uses now are manual point
Combined floodgate formula, manually stir close/open machine can and make-break operation is carried out to circuit.Manual divide-shut brake formula miniature circuit breaker

Refering to Fig. 5, the bridgeware body 282 of bridgeware 280 is sleeved in Handle axis 210, and tabletting 283 and handle dial portion
281 are connected to the periphery of bridgeware body 282.
The utility model also provides a kind of operator's hand that increases from the structure of operating handle when changing, and makes hand more suitable from operating
Freely, conveniently.
As shown in Figure 1 to Figure 3, hand also includes the tumbler 292 being rotatably connected on steady pin 291 from transition components 200,
Steady pin 291 can be for example fixed on the housing of miniature circuit breaker.Bridgeware body 282 and tumbler 292 pass through an elastic card
Component 293 is flexibly connected.Elastic card component 293 include first engaging while and second engaging while, first engaging side and second engaging
The distance between side changes according to the bridgeware body 282 of bridgeware 280 and the relative distance of tumbler 292, is turned with fixed
Change the relative position of part 280 and tumbler 292.
The axle center O1 of the axle center O2 (i.e. the center of rotation of handle our department 220) of Handle axis 210 to steady pin 291 has one to connect
Line, for bridgeware 280 when manual position and automated location, the center O3 of elastic card component 293 is located at the both ends of the line respectively.
Specifically, refering to Fig. 3, bridgeware 280 is located at automated location, and the center O3 of elastic card component 293 is located at handle
On the axle center of axle 210 to the line between the axle center of steady pin 291.When it is manual mode to need by automatic mode switch,
Dialling shank 281 by hand and stir makes bridgeware 280 be located at manual position as shown in Figure 3, now, in elastic card component 293
Heart O3 is located at the axle center O2 of Handle axis 210 under the line between the axle center O1 of steady pin 291.In elastic card component 293
Heart O3 is moved to during the manual position under line by the automated location on line has a centre position, such as Fig. 2
It is shown, now, the center O3 of elastic card component 293 and the axle center O2 of Handle axis 210 to the company between the axle center O1 of steady pin 291
Line is conllinear, i.e. the center O3 of elastic card component 293 is located at the axle center O2 of Handle axis 210 between the axle center O1 of steady pin 291
On line.When centre position, due to the both sides of elastic card component 293 respectively stress in Handle axis 210 and steady pin 291 to reach
Balance.When bridgeware 280 is changed between manual position and automated location, the centre position must be passed through, elasticity
Fastener 293 can pass through stress to be increased suddenly, then stress and the suddenly process of reduction.The process is brought different to operator
Feel, by the conversion of the feel, operator is prompted to be successfully made patten transformation.
From conversion method, it comprises the following steps the hand of miniature circuit breaker of the present utility model：
Under manual mode, bridgeware 280 is located at manual position, and now bridgeware 280 forces in swinging hanger 230 so that pendulum
Dynamic hook 230 swings and can not hung away from rotational hook 240, the rotational hook 240 of electric drive assembly driving with swinging hanger 230
Connect；
Under automatic mode, bridgeware 280 is located at automated location, and now bridgeware 280 is away from swinging hanger 230, electric drive
The rotational hook 240 of Component driver rotate and with swinging hanger 230, moved with band fixed handle our department 220.
Wherein, also comprise the following steps：Set the hand of bridgeware 280 to dial shank 281 to extend among handle our department 220
Outside miniature circuit breaker.
Wherein, also comprise the following steps：Elastic card component 293 is set to connect bridgeware 280 and steady pin 291, handle sheet
The axle center O1 of the center of rotation O2 in portion 220 to steady pin 291 has a line, and bridgeware 280 is in manual position and automated location
Between when being changed, the center of elastic card component 293 moves to conllinear with line from the side of line, then moves to the another of line
Side.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art work as can make various corresponding changes and deformation according to the utility model, but these
Corresponding change and deformation should all belong to the scope of the claims appended by the utility model.
