Description
Technical field
A kind of RCCB is the utility model is related to, particularly relates to the experimental rig power taking knot inside RCCB
Structure.
Background technology
Existing RCCB structure is typically because wiring board and experimental rig take in the upper end of RCCB or lower end
Electricity, the side of wiring board power taking is load-side, and the side of not power taking is enter line side, if reversed, line when product disconnects
Road plate is also at on-state, its service life of the long-term charging effect of wiring board, if pressing test button, because product has broken
Open but still there is electric current test loop, cause product to burn phenomenon, and user consolidates with product because of distribution line or distribution box design
When some modes of connection is inconsistent, causes to design or change loss.And layman can not carry out wiring installation well.Have
With L phases and handle mechanical linkage when portioned product wiring board and experimental rig power taking, i.e., L phases are broken when handle is in open position
Open, L phases are closed when handle is in closing position, but product has been threaded off, but handle locking is in "on" position, product circuit plate L
Mutually and experimental rig is constantly in electriferous state, therefore can equally cause product to burn phenomenon.When separately having a kind of product disconnection, examination
Experiment device can not band conduct, but wiring board is powered all the time, and no matter product is closure or open-circuit line plate all the time in powered old
Change state, therefore have a strong impact on the service life of product.Separately have a kind of product, mechanism links with N poles, but L poles always with circuit
Plate and experimental rig conducting, because there is higher voltage L poles, also exists equivalent to ageing state to wiring board and shorten service life
Risk.Therefore very big risk and deficiency be present with upper type.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides one kind, and L phases have electricity i.e. when product is in and closed a floodgate
Source is that wiring board and experimental rig are powered, RCCB energy normal work.When product is in gate-dividing state or when threading off, nothing
By handle be in where, L phases power supply is disconnected, and wiring board and experimental rig are powered without L phases power supply.Therefore no matter wire is just connect
Or reversal connection wire is on the experimental rig power taking structure of new RCCB of the product without influence.
Above-mentioned purpose is realized, the technical solution adopted in the utility model is：A kind of experimental rig power taking of RCCB
Structure, includes button, torsion spring, N poles moving contact, L poles moving contact and extension spring, and described extension spring one end is connected to RCCB
On housing or the parts fixed with housing, the other end is connected on the L poles moving contact of RCCB, it is characterised in that：Also
Include power taking post or power taking spring, slide the push rod being arranged on RCCB housing, one end of the push rod and N are extremely dynamic
The be hinged swinging end of contact coordinates, and the first torque arm of the other end and torsion spring coordinates, and the second torque arm of torsion spring and the lower end of button are supported
Touching and coordinate, the power taking post or power taking spring electrically connect with L poles moving contact or extension spring, when N poles switch on of moving contact, the first torque arm
