Abstract
The invention discloses a mobile phone charger with a temperature sensor. The mobile phone charger with the temperature sensor comprises a cable (3). The two ends of the cable (3) are connected with a transformer (1) and a connecting plug (5) respectively. A plug pin (2) connected with a socket is arranged on the transformer (1). A line controller (4) is located on the portion, between the transformer (1) and the connecting plug (5), of the cable (3). A thermistor (6) is electrically connected to the line controller (4) through the cable (3). The mobile phone charger has the advantages of being safe in charging.
Description
Technical field:
The present invention relates to the charger for mobile phone technical field, more specifically to a kind of charger for mobile phone with temperature sensing device.
Background technology:
Charger for mobile phone is the daily necessities of using in our daily life, its effect mainly charges the phone, in actual life, people exist many nonstandard places when using charger for mobile phone to charge to mobile phone, even there will be sometimes and also can forget mobile phone is pulled out after mobile phone has charged, therefore the phenomenon that there will be mobile phone to overcharge, this will cause the battery of mobile phone heating battery to be burnt out or causes the phenomenons such as mobile phone deadlock, and because now most batteries of mobile phone is lithium battery, because lithium battery is the responsive type battery, therefore under the excessive situation of generating heat, the phenomenons such as spontaneous combustion or blast can occur, therefore there will be many potential safety hazards.
Summary of the invention:
Purpose of the present invention just is to provide a kind of charger for mobile phone with temperature sensing device, and it has the safer characteristics of charging.
For achieving the above object, a kind of charger for mobile phone with temperature sensing device of the present invention comprises cable, the two ends of described cable are connected with respectively potential device and attachment plug, be provided with the pin be connected with socket on described potential device, be connected with line controller on the cable between potential device and attachment plug, thermistor is electrically connected on line controller by cable.
As technique scheme preferably, a collet is installed on the cable between described line controller and thermistor.
As technique scheme preferably, described thermistor is PTC type thermistor.
As technique scheme preferably, described thermistor is NTC type thermistor.
As technique scheme preferably, be provided with the charging display lamp on described potential device.
As technique scheme preferably, described potential device is arranged in a plastic casing and is made by a voltage control circuit, described charging display lamp is electrically connected in the voltage control circuit.
As technique scheme preferably, be coated with the layer of metal housing on described thermistor.
Beneficial effect of the present invention is: the present invention can automatically cut off charging circuit in the battery of mobile phone excess Temperature; can play first the effect of protection battery of mobile phone; another makes charging safer; prevent battery of mobile phone and cause blast or dieseling because heating is excessive, can protect the safety of the person and property.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is perspective view of the present invention
Fig. 2 is perspective view of the present invention
In figure: 1, potential device; 2, pin; 3, cable; 4, line controller; 5, attachment plug; 6, thermistor; 7, collet; 8, charging display lamp
Embodiment:
Therefore the following stated, only for embodying the preferred embodiment of the principle of the invention, does not limit protection scope of the present invention
Be a kind of embodiment with charger for mobile phone of temperature sensing device of the present invention as shown in Figure 1, 2, it comprises cable 3, the two ends of described cable 3 are connected with respectively potential device 1 and attachment plug 5, be provided with the pin 2 be connected with socket on described potential device 1, be connected with line controller 4 on the cable 3 between potential device 1 and attachment plug 5, thermistor 6 is electrically connected on line controller 4 by cable 3.
One collet 7 is installed on the cable 3 between line controller 4 and thermistor 6, this collet 7 is positioned at the end near thermistor 6, the effect of this collet 7 is clamped in it on mobile phone when being charging, makes thermistor 6 can fully contact with battery of mobile phone or mobile phone back.
In the present embodiment, thermistor 6 can be PTC type thermistor or NTC type thermistor.
Be provided with charging display lamp 8 on potential device 1, potential device 1 is arranged in a plastic casing and is made by a voltage control circuit, described charging display lamp 8 is electrically connected in the voltage control circuit, and this charging display lamp 8 consists of two LED lamps, for showing the state of charging.
Be coated with the layer of metal housing on thermistor 6, this metal shell plays the effect of protection thermistor 6.
Operation principle of the present invention: when the battery of mobile phone temperature raises, thermistor 6 is sensed temperature and is raise, when temperature is greater than the limiting value of setting, line controller 4 control cables lines 3 are in off-state, charged state has also just stopped, and can prevent like this that battery of mobile phone from overcharging and the potential safety hazard brought.
