The utility model discloses a kind of overload protection arrangement, including yoke, it is placed in the housing of breaker；Yoke suction piece, it is placed in above yoke, and one end of yoke suction piece is hinged by jointed shaft and yoke, and jointed shaft is provided with reduction torsion spring；Lug plate, in yoke, static contact is set in its one end；Dropout part, it is rotatably arranged on the housing of breaker is engaged with yoke suction piece, and the moving contact being oppositely arranged with static contact is provided with dropout part；When excessive suddenly by the electric current of terminal plate; yoke can produce electromagnetic force; so that yoke suction piece moves under electromagnetic force towards yoke direction; now yoke suction piece can press dropout part so that moving contact is separated with static contact, reaches the purpose of overload protection; the technical program; it is connected by terminal plate with external power supply, effectively avoids electric current excessive and damage, improve its performance and life-span.
Description
Technical field
Field of circuit breakers is the utility model is related to, more specifically, it relates to a kind of overload protection arrangement.
Background technology
Breaker is a kind of equipment for being used to be switched off and on circuit and have defencive function, and the quality of its performance is directly
It is related to the safety of electricity consumption；Wherein overload protection arrangement as breaker in electric current excessive situation lower static contact and moving contact suddenly
And the executing agency of disconnecting circuit, it is the chief component that open circuit is protected.Wherein electromagnetic overload protection device includes being used to produce
The coil of raw electromagnetic force, it is slidably mounted on the armature that can be moved in coil and under electromagnetic force；It is connected with armature
Support body, driven by armature and moved between the first position and the second position along the axis of coil, support body makes movable contact spring and stationary contact
Piece separates or contact, but its coil is typically to be made of wire, if electric current crosses conference so that coil blows, limitation is disconnected
Road device use range.
Utility model content
, can be with view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of overload protection arrangement
Effectively avoid electric current excessive and damage, improve its performance and life-span.
To achieve the above object, the utility model provides following technical scheme：
A kind of overload protection arrangement, including
Yoke, it is placed in the housing of breaker；
Yoke suction piece, it is placed in above yoke, and one end of yoke suction piece is hinged by jointed shaft and yoke, be hinged
Axle is provided with reduction torsion spring；
Lug plate, in yoke, static contact is set in its one end；
Dropout part, it is rotatably arranged on the housing of breaker is engaged with yoke suction piece, be provided with dropout part with
The moving contact that static contact is oppositely arranged；
When yoke suction piece moves under electromagnetic force towards yoke direction, yoke suction piece can press dropout part so that dynamic
Contact is separated with static contact.
The utility model is further set：One end of the lug plate is connected with terminal screw, the other end of lug plate
The bending part for installing static contact is formed through yoke bending.
The utility model is further set：The dropout part is provided with press section, when static contact and moving contact are in contact,
The press section is placed in the lower section of yoke suction piece.
The utility model is further set：The yoke is placed on arc-chutes.
The utility model beneficial effect：When excessive suddenly by the electric current of terminal plate, yoke can produce electromagnetic force so that
Yoke suction piece under electromagnetic force towards yoke direction move, now yoke suction piece can press dropout part so that moving contact with it is quiet
Contact is separated, and reaches the purpose of overload protection, the technical program, is connected by terminal plate with external power supply, effectively avoids electricity
Flow through big and damage, improve its performance and life-span.
Brief description of the drawings
Fig. 1 is that a kind of overload protection arrangement of the utility model installs sectional view on breaker；
Fig. 2 is a kind of structural representation of overload protection arrangement of the utility model.
Description of reference numerals：1st, yoke；2nd, yoke suction piece；3rd, lug plate；4th, static contact；5th, dropout part；51st, press section；

Embodiment
1 to Fig. 2 a kind of overload protection arrangement of the utility model is described in further details referring to the drawings.
A kind of overload protection arrangement, including yoke 1 are placed in the housing of breaker, and the yoke is placed on arc-chutes, can
With its security performance；Yoke suction piece 2 is placed in the top of yoke 1, and one end of yoke suction piece 2 is cut with scissors by jointed shaft and the phase of yoke 1
Connect, jointed shaft is provided with reduction torsion spring；Lug plate 3, in yoke 1, one end and the terminal screw phase of the lug plate 3
Connection, the other end of lug plate 3 pass through the bending of yoke 1 to form the bending part for installing static contact 4, are easily installed；Dropout part
5, it is rotatably arranged on the housing of breaker is engaged with yoke suction piece 2, is provided with dropout part 5 relative with static contact 4
The moving contact 6 of setting, the dropout part 5 are provided with press section 51, when static contact 4 and moving contact 6 are in contact, the press section
51 are placed in the lower section of yoke suction piece 2；
When excessive suddenly by the electric current of terminal plate, yoke 1 can produce electromagnetic force so that yoke suction piece 2 is in electromagnetic force
Being moved under effect towards the direction of yoke 1, now yoke suction piece 2 can press dropout part 5 so that moving contact 6 is separated with static contact 4,
Reach the purpose of overload protection, the technical program, be connected by terminal plate with external power supply, effectively avoid electric current excessive and damage
It is bad, its performance and life-span are improved, after moving contact 6 separates with static contact 4, the yoke suction piece 2 can be made in reduction torsion spring
With lower reset.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
