The charger 100 according to the utility model embodiment is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, according to the charger 100 of the utility model embodiment, comprise housing, pin, circuit board 10, female seat 20, detector unit 30 and charger break-make processor; Wherein, described pin is located on housing, and it is connected with power electric, and circuit board 10 is arranged on enclosure interior, and it is electrically connected with pin, and female seat 20 is established on the circuit board 10 and is electrically connected with circuit board 10, and female seat 20 is suitable for being electrically connected with terminal.Detector unit 30 is located in female seat 20, and detector unit 30 can detect the temperature of female seat 20 and send feedback signal.Wherein, housing, pin are not shown, and are technology known in those skilled in the art, do not repeat them here, charger break-make processor is electrically connected with detector unit 30, and charger break-make processor can receiving feedback signals control the break-make of female seat 20 and terminal according to feedback signal.Particularly, when the temperature of female seat 20 is lower than safe temperature, female seat 20 and terminal can keep being communicated with, and terminal charge process keeps normal; When the temperature of female seat 20 is higher than safe temperature, charger break-make processor can make female seat 20 and terminal disconnect, and charging process is interrupted.
According to the charger 100 of the utility model embodiment, by detector unit 30 is located in female seat 20, and detector unit 30 is electrically connected with charger break-make processor, detector unit 30 can detect the temperature of female seat 20, and by feedback signal transmission to charger break-make processor, make charger break-make processor can according to the break-make of feedback signal control terminal and female seat 20.
When the temperature of female seat 20 is higher than safe temperature, charger break-make processor can make female seat 20 and charger disconnect, and charging process is interrupted, and avoid the damage of too high the caused wiring board of temperature of female seat 20 or charger etc., charging process is safer; And when the temperature of female seat 20 drops to below safe temperature, can charging process be proceeded, and without the need to changing each device, safeguard procedures are more proper, practical.
Be understandable that, charger 100 is provided with charger break-make processor, and this processor can control charger to the disconnection of terminal charge and continuation; Wherein said processor is technology known in those skilled in the art, does not repeat them here.
The kind of detector unit 30 can have multiple, and such as, detector unit 30 can be thermistor.Particularly, thermistor can be semistor or negative tempperature coefficient thermistor.The volume of thermistor is very little, also relatively rapid to the response of variations in temperature, can detect the variations in temperature of 6 DEG C-10 DEG C.
When the temperature of female seat 20 can charge normal lower than during safe temperature, when the temperature of female seat 20 exceedes safe temperature, such as 80 DEG C time, thermistor can feed back resistance variations signal, charger break-make processor can receive resistance variations signal, and make corresponding emergency processing, to disconnect charging circuit.
Particularly; the mode that charger break-make processor controls charging circuit break-make can be: when the change of temperature causes the resistance of thermistor to change; the voltage in charging circuit can be caused to change; can using voltage signal as the signal transmission in circuit; charger break-make processor can process voltage; to control the break-make of charging circuit, play the object of safeguard protection.
As shown in Figure 1, in embodiments more of the present utility model, detector unit 30 can be located on the outer surface of female seat 20, to detect more easily and delicately the temperature of female seat 20.Charger break-make processor can be established on the circuit board 10, and detector unit 30 is electrically connected with charger break-make processor by diode, detector unit 30 by diode by feedback signal transmission to charger break-make processor.
Alternatively, female seat 20 can be formed as box like structure, and one end of female seat 20 can be opened wide to form charging port 21.Female seat 20 is electrically connected by charger with charger, and particularly, one end of charger is connected with power electric, and the charging port 21 of the female seat 20 on the other end of charger can be connected with terminal, to ensure that female seat 20 is connected with the stable of terminal.
As shown in Figure 2, the upper surface of female seat 20 also can be provided with the bayonet socket 22 be communicated with charging port 21, a part of clamping of terminal can be lived by bayonet socket 22, make the connection of terminal and female seat 20 more firm, avoid the female seat 20 that causes because of reasons such as collisions in charging process and terminal to disconnect and then make the problem that charging process interrupts and occur, make charging process more steady, fail safe is good.
Detector unit 30 can be fitted on the upper surface of female seat 20.Particularly, detector unit 30 can be weldingly connected with female seat 20.Thus, detector unit 30 is by the change of the direct contact induction temperature with female seat 20.When temperature exceedes certain safe temperature, charger break-make processor can disconnect live part according to feedback signals.
As shown in Figure 2, leg 40 can be provided with between detector unit 30 and circuit board 10, detector unit 30 is electrically connected with circuit board 10 by leg 40, the setting of leg 40 can be fixed detector unit 30 further, avoids detector unit 30 be connected insecure with female seat 20 and cause detector unit 30 to depart from charger 100.
The shape of detector unit 30 can have multiple, and such as, detector unit 30 can be formed as circular lamellar body, and the detector unit 30 of circular demihull shape is large with the contact area of female seat 20, and temperature-sensitive is more accurate.For convenience of connecting, a part for detector unit 30 can exceed female seat 20, to be electrically connected with leg 40.Certainly, the structure of detector unit 30 is not limited only to the circular lamellar body shown in figure, and also can be formed as other structure, this is readily appreciated that.
In a word, according to the charger 100 of the utility model embodiment in charging process, when live part abnormal heating time, send signal by charger break-make processor stop charging, avoid overheated caused charger or terminal is damaged, and when on charger 100 for after dropping to safe temperature with the temperature of the female seat 20 be electrically connected, charging process can be proceeded, each device in whole process in charger 100 or terminal can not be damaged, therefore without the need to changing each device, charger 100 is suitable for actual use.
Preferably, charger of the present utility model is USB charger, and detector unit is arranged on USB end.
