Description
Technical field
A kind of socket is the utility model is related to, more particularly, to a kind of protection against electric shock and arc protection safety socket.
Background technology
The security protection of socket needs solve Railway Project：First, solve child is inserted into socket by finger or conductive thread
The protection question to get an electric shock is caused in hole, is asked second, solving to get an electric shock caused by the accidental false touch plug pins of hand when hand takes plug insertion
Topic.
In addition to the safety problem in above-mentioned two use, also there is the problem of another service life in socket, because
Socket is powered plug under many circumstances, that is, when plug inserts or transfers 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 as to big
Amplitude shortens the service life of plug and socket, has special regulation to require the socket of installation using one in some countries for this
Determining must involuntary conversion after the time.
Safety socket mainly solves the problem safe to use of first two especially former, universal solution method at present
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, be inserted into so as to solving child by finger or conductor wire, piece and cause that gets an electric shock to ask in socket
Topic；
The method that finger false touch plug pins cause to get an electric shock when solving plug insertion is then in a kind of cannon plug latch
One section of root wrapped up with insulating barrier, this method be only suitable for latch for cylinder partial plug protection, and China use
Mainly flat latch plug, therefore protective effect has certain limitation.
The problem of electric arc is so as to produce electric spark is produced in socket plug for plug, at present still without substantial solution
Certainly measure.
Sheet mode is blocked for what current safety switch generally used, although with suitable security, is being actually used
In in fact or there is the sex chromosome mosaicism of facilitating used：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 insert, and this problem also often occurs during Double-hole plug, the use to user
Cause to puzzle.
Meanwhile this use hides the safety socket of contact pin because socket is usually powered, 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 one kind danger use in some cases
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, and there is sizable
Potential safety hazard, electric shock accidents easily occurs, but exist conscientiously again in actual life, can not prevent.
It is this it is lack of standardization be using the danger of way to take power, 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 contacts
To be zero line the end of a thread, when both threads be inserted into socket, it is electric on live wire when, electric current can be turned on by electrical appliance and also result in electric shock
Generation, therefore this is each breakneck non-standard operation mode, but is often often occurred again in practical work life.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safety socket for preventing personnel from getting an electric shock, safety
Socket between fire line terminal and live wire sleeve by setting an open type micro switch mechanism, the open type microswitch machine

Moment, acted on the tip that latch contacts or depart from sleeve by 220 alternating voltages and air ionization occur and produce atmospherical discharges
Phenomenon.An indirect open type fine motion in zero line sleeve promotion of the utility model in live wire sleeve and hot terminal son
Switching mechanism, the microswitch only inserts the latch of plug in zero line sleeve and latch just closes conducting after in place,
Preceding in place in the zero line latch of plug is always what is disconnected, and plug zero line latch during sleeve is inserted, before this zero
Line latch and live wire latch contact with socket and bush respectively, then zero line latch just insert in place, promote micro switch mechanism close
Close, live wire is turned on energization with binding post, the latch before live wire sleeve turns on binding post on plug with socket
Sleeve has carried out abundant contact, therefore would not produce electricity in the live wire sleeve energization moment of micro switch mechanism closure, socket
Arc.Then it is open type microswitch first to be disconnected in zero line latch extraction, followed by zero line when plug is transferred to from socket
Depart from sleeve with live wire latch, open type microswitch is already off when departing from sleeve due to latch, therefore production is also not present
The problem of raw electric arc, thus safety socket successfully solve plug asking for ablation of the electric arc to sleeve occur in socket plug
Topic, and ripe microswitch technology ensures that there is enough service life its contact, thus successfully solves socket because plug
Caused by plug produces electric arc the problem of service life.
