Application.The relay of prior art in use, if the unexpected power-off of mains-supplied system, it is impossible to be switched to standby electricity
Source, it is impossible to keep continuing power supply to load, make troubles to productive life.Particularly in the area of power supply instability, such as print
The ground such as degree, the mains-supplied often power-off without omen are stopped the power supply to loading immediately, are brought inconvenience.
The content of the invention
In order to overcome shortcoming and defect present in prior art, it is an object of the invention to provide a kind of switchable power supply
Relay, while civil power is connected, connection stand-by power supply all the way, when civil power is stopped power supply, stands the relay of the present invention
Switch to stand-by power supply to power, normal power supply is continued for load by stand-by power supply, it is ensured that the normal work of load.
Technical scheme is as follows：
A kind of relay of switchable power supply, including it is the first push jack, the second push jack, the first armature, the second armature, first quiet
Piece, the second still, the first moving plate, the second moving plate, First Line bag, the second line bag,
Control is, the logical low-voltage direct electric drive armature of coil, and armature drives push jack, push jack act on sound piece and
Switch, realizes break-make.
First armature drives the motion of the first push jack so as to control the closed and disconnected of the first moving plate and the first still；
Second armature drives the motion of the second push jack so as to control the closed and disconnected of the second moving plate and the second still；
Also include first switch and second switch；One end of the first switch is connected to the first push jack, the other end and
One end electrical connection of two wires bag；One end of the second switch is connected to the second push jack, and the other end is electric with one end of First Line bag
Connection；When first still and the first moving plate are closed, first switch disconnects；When first still and the first moving plate disconnect,
First switch is closed；When second still and the second moving plate are closed, second switch disconnects；Second still and the second moving plate
During disconnection, second switch closure.

Two wires bag route disconnects cannot be conductive.When civil power power-off, the first armature drives the motion of the first push jack to make the first moving plate and first
Still disconnects, while first switch makes first switch moving plate close with first switch still in the presence of push jack, the second moving plate
Or second still connect stand-by power supply power, the second line bag be powered, produce magnetic force, the second armature promote the second push jack, make second
Switch moving plate is separated with second switch still, keeps First Line bag no power.It is worth mentioning that, a kind of changeable electricity of the present invention
After the first switch closure of the relay in source, the conducting of the second coil, the second coil produce the second armature of magnetically-actuated and drive second
Push jack, make the second still and the second moving plate conducting complete stand-by power supply connection, while second switch disconnect guarantee First Line bag without
Method is powered, it is ensured that at civil power, circuit is off.I.e. mains-supplied when, standby electricity is not powered, when standby electricity is powered, civil power
Do not power, it is ensured that Electrical Safety.
Beneficial effects of the present invention：
The relay of the present invention has a circuit of connection stand-by power supply, first switch and second switch respectively with the first push jack
Cleverly connect with the second push jack, the switching being achieved between mains supply and stand-by power supply, during mains-supplied, standby electricity is broken
Open, when civil power has a power failure suddenly, the relay of the present invention can be rapidly switched to stand-by power supply, it is ensured that load is instantly available standby electricity
Source powers, and does not affect to load normal work, so as to ensure being normally carried out in mains failure productive life.
