Comprising battery, the battery is used to carry in the case where the AC power supplies or charging equipment that can not use do not include attaching plug
For charging current.
When exception occurs in connection or charge connector shell fragment occurs abnormal, for example：1. in charge connector power supply shell fragment
Or when between the power supply shell fragment or grounding elastic part in the charging socket of grounding elastic part and electronic equipment introducing conductive foreign matter, quite
A resistance is additionally introduced between the corresponding shell fragment in charging socket of the charge connector shell fragment with electronic equipment, equivalent to
Contact impedance between charge connector shell fragment corresponding with the charging socket of electronic equipment becomes big, i.e. Rs231 and Rs232 increases；
2. when charge connector shell fragment is abnormal due to its reflexed angle of change in shape, cause the shell fragment in the charging socket with electronic equipment
(shell fragment reflexed angle is too small to cause the contact point minimum with socket shell fragment formation area) or electronics are set when the area of contact point is too small
(such as shell fragment surface metal oxidization), charge connector shell fragment and electronics when shell fragment surface in standby charging socket has abnormal
Impedance when shell fragment in the charging socket of equipment is contacted also just is increased, and also contact impedance can be increased, is also equivalent to
Rs231 and Rs232 increases.
It will be produced than just between corresponding shell fragment of the charge connector with the charging socket of electronic equipment in the case of above-mentioned
The contact impedance of even more than hundred times of high tens times of number when often connecting, caused abnormal contact impedance summation is Rs23, Rs23=
Rs231+Rs232, the heating power of abnormal contact impedance is directly proportional to Rs23.
Equivalent circuit diagram as shown in Figure 1B, electric current passes through equivalent resistance by power supply (Power) shell fragment of charge connector
Rs231 flows to the Power shell fragments of charging socket, then is flowed by ground connection (GND) shell fragment and equivalent resistance Rs232 of charging socket
Recharge the GND shell fragments of electric connector.When introducing foreign matter between charge connector and the corresponding shell fragment of the charging socket of electronic equipment,
With shell fragment in the charging socket of electronic equipment it is abnormal when, it will cause pair of the charging socket of charge connector and electronic equipment
Increased dramatically for the contact impedance between shell fragment is answered, the caloric value of charging socket is also increased dramatically, charging socket is there is burning
The hidden danger ruined.And the small heat dispersion of charging jack connector shell fragment area is poor, therefore charging socket overheat is burnt during contact impedance exception
Ruin dangerous so that the security of electronic equipment charging is substantially reduced.
