Switch on wall with overcurrent protection function
Technical field
The present invention relates to switch, is especially switch on wall of the tool with overcurrent protection function.
Background technology
At present, switch on wall all only possesses the function of control circuit switch on the market, but home circuit is in use,
It can cause to use spread of voltage due to a variety of causes, i.e., when in use, electric current has fluctuation to electrical equipment, influences electrical equipment use, very
To damage electrical equipment, although family sets air switch generally at total lock, this air switch is directed to whole home circuit,
And with the electrical equipment quantity increase used in family, the rated current that air switch limits is bigger, does not have but to single electrical equipment
Flow defencive function.
The content of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and offer is a kind of simple and reasonable for structure,
Overcurrent protective device is provided with switch on wall, flows through the wall of automatic shutoff circuit when the electric current of switch on wall exceedes preset value
Wall switch.
The object of the present invention is achieved like this:
Switch on wall with overcurrent protection function, including housing, and the conducting wire and on & off switch being arranged on housing, are also wrapped
Overcurrent protector is included, overcurrent protector is connected in conducting wire, and the electric current for flowing through overcurrent protector equals or exceeds electric current
During preset value, overcurrent protector disconnects the connection with conducting wire;Such switch on wall with overcurrent protection function, by leading
Overcurrent protector is set in electric line, automatically powered off in overcurrent, is effectively protected the electricity being used in series with switch on wall
Device, use are safer.
The purpose of the present invention can also use following technical measures to solve:
As the scheme more optimized, the on & off switch is offseted with overcurrent protector or adjacent, overcurrent protector action pull switch
Key acts, and on & off switch is disconnected electric line, and overcurrent protector is in normally off all the time in conducting wire, when overcurrent protector is examined
Actively triggering and the action of pull switch key when measuring conducting wire excessively stream, disconnects conducting wire by & off switch, realizes that excessively stream is protected
The purpose of protective function.
As more preferably scheme, the overcurrent protector is overcurrent protection bimetal leaf, is set on overcurrent protection bimetal leaf

Shell fragment, electroconductive elastic sheet is set to reach the purpose for disconnecting conducting wire, overcurrent protection movable contact and conduction away from overcurrent protection movable contact
Shell fragment is the service life that Elastic Contact can extend switch on wall.
As more preferably scheme, jump ring is provided with the on & off switch, the jump ring other end offsets with housing, and jump ring makes switch
There is paragraph sense during key pressing, usage experience is more preferably.
As more preferably scheme, the bottom of the on & off switch is provided with push rod, and push rod offsets or close with electroconductive elastic sheet, pushes away
Bar pushes electroconductive elastic sheet and realizes the purpose for disconnecting conducting wire.
As more preferably scheme, jack assemblies, microswitch and microswitch are additionally provided with the conducting wire and is touched
Component, one end connection jack assemblies of the microswitch triggering component, the other end is adjacent or close with microswitch, and fine motion is opened
Pass is connected in the conducting wire, and microswitch is open in usual, and microswitch and microswitch triggering component form socket
One safety device of component, improve jack assemblies security performance.
As more preferably scheme, the jack assemblies include three resilient socket jump rings, and they are installed in a manner of isosceles triangle
On housing, microswitch triggering component includes fixed seat, briquetting, extension spring and Contact plate, and fixed seat is connected to one of bullet
Property socket jump ring on, extension spring is arranged between fixed seat and Contact plate with oblique direction, and Contact plate one end and fixed seat pivot connect
Connect, briquetting is placed in described resilient socket jump ring bottom with upper and lower manner, and briquetting bottom surface offsets with extension spring, Contact plate with it is micro-
Dynamic switch is adjacent or offsets, and in 3-phase plug insertion resilient socket jump ring, when foreign matter inserts resilient socket jump ring, foreign matter can not be complete
Complete to push briquetting, Contact plate is in microswitch and is mutually in obstructed electricity condition from state, i.e. resilient socket jump ring, avoids occurring
The contingency of electric shock.
As more preferably scheme, the housing includes overcurrent protection drain pan, socket outlet adapter, and panel, and the excessively stream is protected
Overcurrent protection bimetal leaf, the first wiring copper post and the second wiring copper post are provided with river bottom protection shell, is set in the socket outlet adapter
There are jack assemblies, microswitch and microswitch triggering component, panel side is provided with the movable on & off switch, and panel is another
Side is provided with jack assemblies hole, on the socket outlet adapter below the panel, is provided with above one of resilient socket jump ring

One back-moving spring, the back-moving spring other end offset with socket outlet adapter, and protection against electric shock insulation protection frame avoids foreign matter from inserting resilient socket
In jump ring, the security of switch on wall is improved.
Beneficial effects of the present invention are as follows:
(1)Such switch on wall with overcurrent protection function, by setting overcurrent protector in conducting wire, in overcurrent
When automatically power off, be effectively protected the electrical equipment being used in series with switch on wall, use is safer.
(2)Secondly, overcurrent protector is overcurrent protection bimetal leaf, and overcurrent protection bimetal leaf is in conducting wire excessively stream
When, cut-off by deformation pull switch key and convince electric line by patient analysis, overcurrent protection bimetal leaf can also self-resetting, or pass through switch
Key resets, such a to design the function of not only making switch on wall have overcurrent protection, and user can also pass through the change of on & off switch
Recognize the phenomenon of conducting wire overcurrent, eliminate safe hidden trouble in time.
(3)Further, such switch on wall with overcurrent protection function is additionally provided with jack assemblies, i.e. three-phase socket, socket
The resilient socket jump ring of component, is not only protected by microswitch triggering component and microswitch, and be additionally provided with can
Resetting protection against electric shock insulation protection frame prevents foreign matter insertion from getting an electric shock, and multilayer protects the security for being greatly improved product.
