Description
Technical field
This utility model and a kind of RCCB, particularly it is a kind of can positive and negative wiring RCCB.
Background technology
Existing RCCB structure is typically because wiring board and assay device take in the upper end or lower end of RCCB
Electricity, the side of wiring board power taking is load-side, and the side of not power taking is into line side, if reversed, even if the line when product disconnects
Road plate is also at on-state, the long-term charging effect of wiring board its service life, 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 because distribution line or distribution box are designed with product
When some modes of connection is inconsistent, cause to design or change loss.And layman can not well carry out wiring installation.Have
L phases are broken when being in open position with L phases and handle mechanical linkage, i.e. handle when portioned product wiring board and assay device power taking
Open, L phases are closed when handle is in closing position, but product is threaded off, but handle locking is in "on" position, product circuit plate L
Mutually electriferous state is constantly in assay device, therefore can equally cause product to burn phenomenon.When separately having a class product to disconnect, 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.Therefore there is very big risk and deficiency with upper type.
The content of the invention
This utility model overcomes the shortcomings of that prior art is present, there is provided a kind of L phases have electricity i.e. when product is in combined floodgate
Source is that wiring board and assay device are powered, RCCB energy normal work.When product is in gate-dividing state or when threading off, nothing
By handle in where, L phases power supply disconnects, and wiring board and assay device are powered without L phase power supplys.Therefore no matter wire is just being connect
Or reversal connection wire on product without affect it is new can positive and negative wiring RCCB.
