Upper end position, and static contact has breaker breaking capacity and stability tremendous influence, and design is rational quiet
The structure of contact is always the direction studied.
The content of the invention
In view of this, the purpose of this utility model is that solution operating mechanism is complicated, static contact structure is reasonably moulded
Case circuit breaker.
In order to achieve the goal above, the utility model use such a breaker of plastic casing, including pedestal, operating mechanism,
Contact system and arc quenching system, the contact system include moving contact component and static contact, and the operating mechanism includes base
Frame, with pedestal rotation connection rotational handle, the pedestal include symmetrically arranged two blocks of side plates, the rotational handle include pair
Claim the two pieces of rocking arms set, the locating part and round boss that oriented side plate lateral direction is set on the side plate, the locating part
" work " word through hole is formed between round boss, described locating part one end is connected with through hole edge, and the locating part is with leading to
Form a /V gap between hole, the rocking arm center bottom forms a U-shaped opening being adapted to round boss, side plate and
Connection between rocking arm is that an integrally formed round boss is directly set on side plate, the U formed with rocking arm center bottom
Type opening adaptation realizes rotation connection, changes previous shaft connection, reduces the increase of attachment, and set finite place piece
Improve the reliability and stability of rocking arm rotation.
The utility model further set static contact include connecting portion, connecting portion include symmetrically arranged first it is long-armed and
Second is long-armed, first it is long-armed with second it is long-armed between form cavity, be provided with contact platform below cavity, set on the platform of contact
There is a contact, contact platform is by the way that semicircle changeover portion and first be long-armed and the second long-armed integrally connected.Contact platform is arranged on
The lower section of connecting portion cavity changes the structure of current static contact, and when dynamic/static contact touches, moving contact component stretches into cavity
Interior, the contact between dynamic and static contact is relatively reliable.
The utility model further sets the lower end of pedestal to be provided with the first cursor and the second cursor, described first turn
It is realized by shaft between swing arm and the second cursor and is rotatablely connected with moving contact component, the shaft is arranged in intermediate
Moving contact component.It is more simple in structure by the connection of the first cursor and the second cursor realization pedestal and moving contact component
It is single.
The utility model further sets the pedestal to be integrally formed part.Integrated formed structure is more reasonable, and into
This is low.
Description of the drawings
Fig. 1 is the sectional view of the utility model embodiment.
Fig. 2 is the structure diagram of the utility model embodiment rocking arm and pedestal.
Fig. 3 is the utility model embodiment pedestal and the schematic diagram of moving contact component assembling.
Fig. 4 is the structure diagram of the utility model embodiment static contact.
Specific embodiment
The utility model is described further below in conjunction with attached drawing.
As shown in Figs 1-4, the utility model is a kind of breaker of plastic casing, including pedestal 1, operating mechanism 2, contact system 3
And arc quenching system 4, contact system 3 include moving contact component 31 and static contact 32, operating mechanism 2 includes pedestal 21 and base
The rotational handle 22 that frame 21 is rotatablely connected, the part integrated formed structures that are integrally formed of pedestal 21 are more reasonable and at low cost,
Pedestal 21 includes symmetrically arranged two blocks of side plates 23, and rotational handle 22 includes symmetrically arranged two pieces of rocking arms 24, has on side plate 23
To 23 lateral direction of side plate set locating part 231 and round boss 232, round boss 232 may be configured as it is hollow or solid,
" work " word through hole 233 is formed between locating part 231 and round boss 232,231 one end of locating part connects with 233 edge of through hole
It connects, a /V gap is formed between locating part 231 and through hole 233,24 center bottom of rocking arm forms one and fitted with round boss
The U-shaped opening 241 matched somebody with somebody, the connection between side plate 23 and rocking arm 24 are directly to set integrally formed circle convex on side plate 23
Platform is adapted to realization rotation connection with the U-shaped opening 241 that 24 center bottom of rocking arm is formed, and changes previous shaft connection, reduces
The increase of attachment, structure is more simple, and finite place piece is set to improve the reliability and stability of the rotation of rocking arm 24, base
The lower end of frame 21 is provided with the first cursor 211 and the second cursor 212, between the first cursor 211 and the second cursor 212
It is realized by shaft and is rotatablely connected with moving contact component 31, shaft is arranged in intermediate moving contact component 31.Static contact 32
Including connecting portion 321, connecting portion 321 include symmetrically arranged first long-armed 322 and second long-armed 323, first long-armed 322 with
Cavity 324 is formed between second long-armed 323,324 lower section of cavity is provided with contact platform 325, contact is provided on the platform of contact
326, contact platform 325 is set by long-armed 322 and second long-armed 323 integrally connected of semicircle changeover portion and first, contact platform
The structure in the lower section of connecting portion cavity, changing current static contact is put, when dynamic/static contact touches, moving contact component stretches into
In cavity, the contact between dynamic and static contact is relatively reliable.
