Technical field
The utility model is related to electronic fields, and in particular to a kind of charger for preventing metal joint exposed.
Background technology
Phone charger can substantially be divided into traveling charger, base charger and maintenance type charger, general user and connect
Tactile mainly two kinds of front.Domestic civilian rated voltage is 220V, and the voltage that mobile phone is born is 2-10V, therefore is not
It can directly be charged the phone with civilian electricity.The use of phone charger is exactly that the high-voltage pulse of 220V is converted to the low of 5V
Alternating current is become 5V stable DCs by pressure pulse using rectification, regulator circuit.That is, the charger of mobile phone rises
Become the effect of low-voltage direct to one from High Level AC Voltage.
It but will be directly that not will produce any electric current on mobile phone charging bottom device to socket, only mobile phone connected, is filled
Electric appliance can just start to work, and size of current depends on the state of load：As long as within one's power, load needs much
Electric current, charger is provided with great electric current.If the electric current that load needs has been more than on the electric current that charger is capable of providing
Limit, then charger will export always this maximum electric current.This is because charger internal would generally design protection electricity
Road, once output current is excessive, will trigger protection mechanism, pause electric current output, avoid causing danger, that is to say, that even if
Charger can export the electric current of 50A, and the recharge logic of your interior of mobile phone is controlled if it is 2A, and charging current still can be limited
In 2A, charging rate is unaffected system substantially.
Using charger charge during, when on electric socket board clamp plug metal connector intermediate plate clamping force not
The distance of jack of the enough or intermediate plate on electric socket board is less than normal, after charger being caused to be inserted on the jack of electric socket board, metal
One end on connector close to plug is exposed to outside, since metal joint is in conduction state, is exposed to external metal
Connector has great security risk, is easy to happen electric shock accidents.
Utility model content
