Wherein, described alarm module is provided with alarm tone volume adjuster.
Wherein, on described shell 2, be also provided with the operating position of the volume adjusting of alarm tone.
Wherein, described alarm module also has, and can export the warning lamp 7 of alarm light when the lead-out terminal 12 that above-mentioned voltage transitions portion detected in described connection detection module 21 disconnects with above-mentioned e-machine displaying merchandise.
Wherein, described electronic product, a kind ofly as displaying merchandise, for the mobile phone of showing or camera or IPAD electronic product Anti-theft charger 1, to there is warning function, when electronic product is pulled out or when charger electric wire is cut off, electronic product Anti-theft charger 1 will automatically send chimes of doom or alarm lamp lights from charger connector 5 as mobile phone.
A kind of electronic product Anti-theft charger 1 has warning function, electronic product Anti-theft charger 1 contacts with electronic product interface 52 by connector 5, charge as mobile phone to electronic product, when connector 5 is pulled out from electronic product interface 52, or charger electric wire is cut off or cuts off etc., the connection detection module 21 in electronic product Anti-theft charger 1 can detect automatically, thereby alarm module is started, buzzer 6 gives a warning automatically, and warning lamp 7 lights automatically.
Voltage transformation module 11 one end are connected with attaching plug 3, and be fixed on shell 2 one sides, the other end is connected with power line, and be fixed on a side of shell 2, described connector 5 is connected with power line, described voltage transformation module 11 consists of lead-out terminal 12 and switching power circuit, described switching power circuit can be primary side rectification circuit, smoothing circuit, the change-over circuit of primary coil and secondary coil, secondary commutation circuit, secondary smoothing circuit, Switching Power Supply control integration circuit etc., the alternating voltage (as 220 volts) that described voltage transformation module 11 can be come in attaching plug 3 transmission converts galvanic current to and presses (as 3 volts or 5 volts), then by lead-out terminal 12, to electronic product, charge.
Whether connection detection module 21 can detect charger by voltage transformation module 11 and to electronic product, power, and connection detection module 21 can be by comparator 22, resistance 23,24 and 25 and the formation such as triode 26.
Alarm module, when charger stops to electronic product power supply, voltage transformation module 11 is to connection detection module 21 output signals, and connection detection module 21 is to alarm output module transmission of signal simultaneously, and buzzer 6 just sends chimes of doom, and warning lamp 7 just lights.Alarm output module is provided with buzzer 66 and warning lamp 77, variable resistor 32, triode 33, change over switch 34, integrated circuit 35 etc., also can set up volume operation portion 8 in alarm output module, volume operation portion 88 is comprised of variable resistor 32 and control switch 34, can be switched and control the resistance of variable resistor 32 by control switch.
First, when attaching plug 33 is connected on the power supply of daily electricity consumption (as 220V), voltage transformation module 1111 converts alternating current to the direct current of default pressure value, the lead-out terminal 1212 of voltage transformation module 1111 is connected as handset port by power line and connector 5 and electronic product with 13, to mobile phone, provide working power, in the instant uncharged situation of battery of mobile phone, also enough mobile phone normal operations.
When charger connector 5 inserts mobile phone, the lead-out terminal 12 of voltage transformation module 11 is connected with mobile phone, the resistance of the resistance 23,24 in mobile phone internal resistance and connection detection module 2121 and 25 combinations becomes very large, be enough to make the magnitude of voltage of comparator 22 outputs very little, making triode 26 collector currents is 0, and alarm module circuit disconnects.
When charger connector 5 is extracted from mobile phone, or charger power cord is when disconnecting or being cut off or cut off (being mobile phone and charger circuit disconnection), lead-out terminal 12 and the mobile phone of voltage transformation module 11 disconnect, the output voltage of comparator 22 becomes high level, make triode 26 open-minded, alarm module circuit is opened, buzzer 6 starts and sends the sound, can allow salesman know that mobile phone stolen by people the very first time, can take relevant action at once, warning lamp 7 is opened, and can allow salesman know the position of stolen mobile phone the very first time, can accurately locate.
A kind of electronic product Anti-theft charger 1 is generally used in occasions such as hypermarket or fairs, in case electronic product is stolen.For example, in a mobile phone shop, mobile phone charges by Anti-theft charger, by control switch, open alarm function, regulate warning volume, mobile phone is placed on showing stand, charger is placed in to the untouchable place of client (other people), client can carry out practical operation to mobile phone, strengthens and uses impression.When mobile phone is pulled out from the connector 5 of charger by people, or have people to attempt with scissors or pocket knife, the power line of charger being cut off, the burglary-resisting system of charger starts, and buzzer 6 devices of charger are horn blew just, and warning lamp 7 lights simultaneously.
In the present embodiment, electronic product Anti-theft charger 1 has buzzer 6 and warning lamp 7, both can sound the alarm and also can send warning lamp 7, but Anti-theft charger also can only provide buzzer 6 or warning lamp 7 is only provided, can remind equally electronic product everyone know that whether product stolen.
Above execution mode is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection range of claims of the present utility model.
