Description
Technical field
The present invention relates to a kind of socket, more particularly, to a kind of protection against electric shock and arc protection safety socket.
Background technology
The security protection of socket needs to solve Railway Project：One is to solve child finger or conductive thread are inserted into socket
The protection question got an electric shock is caused in hole, two be to solve the electric shock that the accidental false touch plug pins of hand are caused when hand takes plug insertion to ask
Topic.
In addition to the safety problem in above-mentioned two use, the problem of also there is another service life in socket, because
Socket is powered plug under many circumstances, that is, when plug is inserted or is transferred to, the power supply of the electrical appliance of plug one end
Often it is open, at this moment when plug is in insertion or dial-out, contacts or depart from the wink of the sleeve of socket in the latch of plug
Between can produce electric arc, electric spark occur, and the generation of this electric spark not only can ablation socket and bush surface and can be on surface
Oxide is formed, causes the loose contact between sleeve and plug pins, causes and even results in fire using process heating, so that greatly
Amplitude shortens the service life of plug and socket, is that this has special regulation to require that the socket installed is using one in some countries
Determining must involuntary conversion after the time.
Current safety socket is mainly the use safety problem for solving first two especially former, universal solution
Be socket aperture install shielding plate, this shielding plate mounted in socket sleeve and jack between, only when plug latch simultaneously
Shielding plate can just be opened during insertion, cause that gets an electric shock to ask in socket so as to solve child and be inserted into finger or conductor wire, piece
Topic；
Finger false touch plug pins cause the method got an electric shock to be then in a kind of cannon plug latch when solving plug insertion
One section of root wrapped up with insulating barrier, this method is only suitable for protection of the latch for the partial plug of cylinder, and China uses
Mainly flat latch plug, therefore protective effect has certain limitation.
Electric arc is produced so as to the problem of producing electric spark, at present still without substantial solution in socket plug for plug
Certainly measure.
Sheet mode is blocked for what current safety switch was generally used, although with suitable security, in actual use
In still there is the sex chromosome mosaicism of facilitating used in fact：If three hole plugs do not have ground wire latch, plug can not just be opened
The screening contact pin of another two jack, plug can not just be inserted, and this problem also often occurs during Double-hole plug, the use to user
Cause puzzlement.
Meanwhile, this safety socket using screening contact pin is usually powered due to socket, when in use to the psychology of people
On there is also certain influence.
Current safety socket can not also solve another question, when being exactly that a kind of danger in some cases is used
Safety problem.In some occasions, the occasion especially in some not bery specifications, when no plug needs to use electric power,
Some people can be wrapped with live wire and zero line the end of a thread a small wooden, small bamboo chip etc. using these small woodens or small bamboo chip will with from
Live wire and the zero line that electrical equipment is drawn are inserted into power taking in the jack of socket, even directly with hand by the live wire drawn from electrical equipment with
Zero line, which is inserted into the jack of socket, carries out power taking, and this nonstandard way to take power is breakneck, exists sizable
Potential safety hazard, easily occur electric shock accidents, but exist conscientiously again in actual life, it is impossible to prevent.
The danger of this use way to take power lack of standardization is, if on the one hand operator both threads are inserted into it is slotting
If finger contacts live wire the end of a thread during seat, electric shock accidents will can be directly caused, on the other hand, if operator's finger is contacted
To be zero line the end of a thread, when both threads are inserted into socket, electricity on live wire, electric current can also result in electric shock by electrical appliance conducting
Generation, therefore this is each breakneck non-standard operation mode, but is often often occurred again in practical work life.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of safety socket for preventing personnel from getting an electric shock, safety socket
By setting an open type micro switch mechanism between fire line terminal and live wire sleeve, the open type micro switch mechanism is only
There is the live wire sleeve that can just close, make socket after the zero line latch of plug is inserted into the zero line sleeve of socket to be powered, otherwise insert
The live wire sleeve of seat is simultaneously not charged, so as to prevent personnel from getting an electric shock.
The safety socket of the present invention prevents that the further principle that personnel get an electric shock from being：Child etc. inserts finger or conductive filament
When being played into socket aperture, a finger generally can be only inserted, therefore insert whether being inserted into live wire socket aperture, or insertion zero line
Bore, will not get an electric shock, because when being inserted into live wire socket aperture, due to not there is plug pins insertion in zero line, therefore
Live wire sleeve is not charged, will not cause electric shock, and when being inserted into null line hole, although live wire sleeve may be caused powered, but
Zero line sleeve is not charged in itself, therefore will not also get an electric shock.Even if zero line can be inserted into finger or conductive filament and insert simultaneously by having
In hole and firewire jack, but the micro switch mechanism of safety socket needs and reaches shapes of national standard plug pins and intensity etc.
The triggering push rod of micro switch mechanism could be triggered, therefore will not also cause the generation of electric shock accidents.
The reason for plug produces electric arc in socket plug is when the latch of plug is contacted or departed from the sleeve of socket
Moment, acted on that latch is contacted with sleeve or air ionization occurs in the tip that departs from and produces atmospherical discharges by 220 alternating voltages
Phenomenon.An indirect open type microswitch in zero line sleeve promotion of the present invention in live wire sleeve and hot terminal son
Mechanism, the latch and latch that the microswitch only inserts plug in zero line sleeve just closes conducting after in place, is inserting
Head zero line latch in place it is preceding be always disconnect, and plug zero line latch insertion sleeve during, before this zero line insert
Pin and live wire latch contacted respectively with socket and bush, then zero line latch just insert in place, promotion micro switch mechanism close, make
Live wire is turned on binding post and is powered, and sleeve of the latch before live wire sleeve is turned on binding post on plug with socket enters
Gone abundant contact, thus close in micro switch mechanism, the live wire sleeve of socket moment that is powered would not produce electric arc.Plug
Then it is first to disconnect open type microswitch in zero line latch extraction, followed by zero line and live wire when being transferred to from socket
Latch departs from sleeve, and due to latch, when departing from sleeve, open type microswitch is already off, therefore generation electric arc is also not present
The problem of, thus safety socket successfully solves plug the problem of electric arc is to the ablation of sleeve occurs in socket plug, and
Ripe microswitch technology ensures that there is enough service life its contact, thus successfully solves socket because plug plug is produced
Caused by raw electric arc the problem of service life.
