Require also more and more higher.Charger is connected with electronic equipment by charge connector, realizes electron equipment charge, such as schemes
Shown in 1, the charging modes of electronic equipment include following several ways: the attaching plug of charger obtains to be inserted from conventional electric power
The electric power of seat, charger converts alternating current to the unidirectional current of predetermined voltage using general components, and this predetermined voltage is applied to
Via normal charge adapter, electronic equipment is charged；Or, attaching plug can be the routine including general components
Dc attaching plug, by the dc electric current entering and voltage, it is suitable for be charged to electronic equipment to be transformed into for this general components
Dc electric current and voltage, such that it is able to be charged to electronic equipment by charge connector；Again or, charger can wrap
Containing battery, this battery be used for do not have can using ac power supply or charger do not include providing in the case of attaching plug
Charging current.

Extraneous introduce conductive foreign body on charging plug or charging socket, as shown in accompanying drawing 2a and 2b, conductive foreign body is just across filling
When between charging socket power supply (power) shell fragment of the charging plug of electric connector or electronic equipment and ground connection (gnd) shell fragment, will
Can make to be formed path between power shell fragment and gnd shell fragment.
Specifically, conductive foreign body can be equivalent to a resistance, be connected between power shell fragment and gnd shell fragment it is assumed that
The conductive foreign body introducing on the charging plug of charge connector is equivalent to resistance rp202, and equivalent circuit diagram as shown in Figure 2 c fills
Power shell fragment in the charging plug of electric connector is connected with gnd shell fragment by resistance rp202, thus forming leakage path, and
Resistance rp202 is caused to generate heat.And the conductive foreign body introducing in the charging socket of electronic equipment is equivalent to resistance rp301, such as scheme
Equivalent circuit diagram shown in 2d, its leakage path is that charging socket power shell fragment passes through resistance rp301 to gnd shell fragment, causes electricity
Resistance rp301 heating.
And according to heating power p=u2/ r understand, u is the voltage being carried in conductive foreign body two ends, r be conductive foreign body etc.
Effect resistance, for example, when conductive foreign body resistance is 2.5 ω, the normal contact impedance of negligible charge connector, now conductive foreign body
Resistance both end voltage u is equal to the voltage at power shell fragment two ends.With the modal maximum output of current smart mobile phone charger
To calculate as a example the voltage 5v at power 10w, power shell fragment two ends, now leakage current i=u/r=2a, charging will not be caused to set
Standby overcurrent protection, and now calculate to obtain p=(5 × 5)/2.5=10w, that is, the heating power of conductive foreign body reaches 10w, if with current
Gradually popularize fill soon charger calculate, the voltage at power shell fragment two ends up to 12v, when the resistance of conductive foreign body is some
During scope, the heating power of conductive foreign body is likely to be breached tens of watts, the heating power of the such rank contact flat spring to small area
For be very huge, can lead to its high temperature quickly, constitute and burn charge connector and electronic equipment charge port material nearby
Risk, be that the use of electronic equipment brings very big potential safety hazard.
