Abstract
The utility model discloses a kind of convenient multiplex roles USB charger; comprise the power line of charger body and connecting charger main body; this charger built-in has circuit board; it is characterized in that: described charger body is provided with multiple USB interface, described circuit board is built-in with and prevents from overcharging and the intelligent protection system of short circuit and intelligent circuit breaking protective system.The convenient multiplex roles USB charger of the one that the utility model obtains, this charger adopts multiple USB interface, user's instructions for use can be met, save space, circuit board is installed intelligent protection system effectively to prevent from overcharging and short circuit, the inside is provided with intelligent circuit breaking protective system simultaneously, if when finding that certain mouth of charger can not charge, intelligence circuit breaking protective system can according to its current limliting chip that automatically resets, the situation that Real-Time Monitoring electric current exports, can by complete for charger power-off once there is the output of abnormal electric current, and then connect, normal power supply can be recovered.
Description
Technical field
The utility model relates to a kind of power supply adaptor, particularly a kind of convenient multiplex roles USB charger.
Background technology
Many electronic equipments such as mobile phone, Mp 3 player and digital camera etc. charge by the USB port in computer or by USB alternating current (AC) adapter that can be inserted in wall socket or supply socket.Computer is required to open by the charging device of the USB port on computer and what also prevent other is such as the ancillary equipment access port in use of mouse and memory device.By using USB AC adapter, electronic equipment can charge on wall socket or supply socket.A part for adapter has the AC plug joined in the AC jack of wall socket, and another part of adapter has USB port to be connected with the USB connector of electronic equipment to be charged or electrical equipment simultaneously; The USB charger that distinct device is different, can find that this voltage is excessive, and another charging is too slow in use procedure.Insert row always forcibly occupy by different chargers, namely will to reach the ratio of anticipation very fast for charging rate, needs multiple different charger to be remembered and is inserted in that insert row makes can be more unordered, compares to account for area and also use inconvenience.
Current charger easily produces electric shock simultaneously, dangerous, overheated, can fire-prone.
Utility model content
The purpose of this utility model provides a kind of structure simple, easy for installation and the convenient multiplex roles USB charger of the one of safety to solve above-mentioned the deficiencies in the prior art.
To achieve these goals; the convenient multiplex roles USB charger of one designed by the utility model; comprise the power line of charger body and connecting charger main body; this charger built-in has circuit board; it is characterized in that: described charger body is provided with multiple USB interface, described circuit board is built-in with and prevents from overcharging and the intelligent protection system of short circuit and intelligent circuit breaking protective system.
Preferably, described charger body adopts ABS flame resistant material to make.
Preferably, described charger body upper and lower surface has the radiating groove for radiating convection.
The convenient multiplex roles USB charger of the one that the utility model obtains, this charger adopts multiple USB interface, user's instructions for use can be met, save space, circuit board is installed intelligent protection system effectively to prevent from overcharging and short circuit, the inside is provided with intelligent circuit breaking protective system simultaneously, if when finding that certain mouth of charger can not charge, intelligence circuit breaking protective system can according to its current limliting chip that automatically resets, the situation that Real-Time Monitoring electric current exports, can by complete for charger power-off once there is the output of abnormal electric current, and then connect, normal power supply can be recovered.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of the USB interface in Fig. 1.
Fig. 3 Fig. 1 has radiating groove schematic diagram.
Fig. 4 is the schematic diagram of circuit board.
In figure: charger body 1, power line 2, USB interface 3, circuit board 4, intelligent protection system 5, intelligent circuit breaking protective system 6.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figures 1 to 4; the convenient multiplex roles USB charger of the one that the utility model provides; comprise the power line 2 of charger body 1 and connecting charger main body; this charger body 1 is built-in with circuit board 4; described charger body 1 is provided with multiple USB interface 3; every two USB interface 3 form the USB interface of a group, described circuit board 4 is built-in with and prevents from overcharging and the intelligent protection system 5 of short circuit and intelligent circuit breaking protective system 6.
Further, described charger body 1 adopts ABS flame resistant material to make, and can stop potential safety hazard.
Further, described charger body 1 upper and lower surface has the radiating groove 10 for radiating convection, and good heat radiating improves fail safe.
For the convenient multiplex roles USB charger of one that above-mentioned design obtains, this charger adopts multiple USB interface, user's instructions for use can be met, save space, charger body 1 outer surface can process one deck frosted layer, increase texture, the input current of USB interface 3 mainly contains the charging requirement that 1.5A or 2.1A meets different electronic product, electric current plate also can install a voltage-stabilizing protection system, the further safety and stability of work can be made, circuit board is installed intelligent protection system 4 effectively to prevent from overcharging and short circuit, the inside is provided with intelligent circuit breaking protective system 6 simultaneously, if when finding that certain mouth of charger can not charge, intelligence circuit breaking protective system can according to its current limliting chip that automatically resets, the current limliting that automatically resets chip can adopt MAXIX485 in the market, the situation that Real-Time Monitoring electric current exports, can by complete for charger power-off protection once there is the output of abnormal electric current, connect again after extracting charging device, normal power supply can be recovered.
For utility model person of an ordinary skill in the technical field; under the prerequisite not departing from utility model design; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that claims of being submitted to by utility model are determined.
