Abstract
A kind of 2.0 interface of USB AF with quick charge conversion function, is related to the 2.0 interfacing field USB AF.Solving existing 2.0 interface of USB AF cannot achieve the technical deficiency of adaptive switching quick charge, include metal shell, glue core and terminal；Terminal and the injection molding of glue core are fixed, and metal shell is placed on outside glue core；The terminal includes a pair of of data and a pair of power source terminals；It is conductively connected it is characterized by: the terminal is also a pair of for cooperating USB male end, switches the power supply terminal output electric current for power output circuit and the inspection terminal of detection signal is provided.Pass through the respective terminal and inspection terminal connection in electrical contact on docking device Male end connector, power output circuit is to can get the control signal that a need switch to fast charge mode, power output circuit increases original a pair of power source terminals and exports electric current, realizes quick charge, good compatibility.
Description
Technical field
The utility model relates to arrive the 2.0 interfacing field USB AF.
Background technique
The power supply terminal of existing 2.0 interface of USB AF for data transmission generally uses the electric current of 500mA to export,
Electric current is relatively small, is unable to satisfy the demand of quick charge, does not have and is switched over according to docking device size of current demand, fits
Answering property is poor.
Utility model content
In conclusion utility model aims to solve existing 2.0 interfaces of USB AF cannot achieve adaptive switching
The technical deficiency of quick charge, and propose a kind of 2.0 interface of USB AF with quick charge conversion function.
To solve the technical issues of the utility model is proposed, the technical solution of use are as follows:
A kind of 2.0 interface of USB AF with quick charge conversion function, includes metal shell, glue core and terminal；End
Son is fixed with the injection molding of glue core, and metal shell is placed on outside glue core；The terminal includes a pair of of data and a pair of power source terminals；
It is conductively connected it is characterized by: the terminal is also a pair of for cooperating USB male end, switches the electricity for power output circuit
Source terminal exports electric current and provides the inspection terminal of detection signal.
Preferred scheme includes:
The conductive contact surfaces of the inspection terminal, which are placed on glue core, is located at data terminal forward position.
The width of the power supply terminal is 1.5mm.
Data terminal, power supply terminal and the inspection terminal is L-shaped structure, and glue core tail end is equipped with coating data terminal
Son, power supply terminal and inspection terminal vertical tails.
The utility model has the following beneficial effects: the utility model increases a pair on the basis of traditional 2.0 interface of USB AF
Inspection terminal passes through docking device male end when docking device needs high current to carry out quick charge with the utility model grafting
Respective terminal and inspection terminal connection in electrical contact on connector, power output circuit switch to fastly to can get a need
The control signal of fast charge mode, power output circuit increase original a pair of power source terminals and export electric current, realize quick charge,
Good compatibility.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is structural schematic diagram when the utility model is free of metal shell；
Fig. 3 is that the utility model is free of another angled arrangement schematic diagram when metal shell；
Fig. 4 is the decomposition texture schematic diagram of the utility model.
Specific embodiment
The structure of the utility model is made further below in conjunction with attached drawing and the utility model preferred specific embodiment
Explanation.
Referring to figs. 1 to shown in Fig. 4, the utility model has 2.0 interface of USB AF of quick charge conversion function, packet
Metal shell 1, glue core 2 and terminal 3 are included；Terminal 3 and the injection molding of glue core 2 are fixed, and metal shell 1 is placed on outside glue core 2；Described
Terminal 3 includes a pair of of data 31 and a pair of power source terminals 32；Also a pair of of inspection terminal 33 of the terminal.
In application process, inspection terminal 33 is connected the utility model with the power output circuit on PCB, in sense terminal
Son 33 detects when having the terminal for cooperating conductive connection with it in the USB male end of docking device, two survey resistance value between terminals 33 or
Current value will generate variation, provide control signal, power supply to provide for power output circuit and switch to quick charge module
Output circuit controls the output electric current for increasing power supply terminal 32 according to the control signal, such as original 500mA is exported, and increases
Electric current to 1A or 1.5A or bigger exports, and realizes quick charge.
Preferable scheme is that: the conductive contact surfaces of the inspection terminal 33, which are placed on glue core, is located at 31 front side of data terminal
Position that is to say the front row USB3.0 terminal position.
The width of the power supply terminal 32 increases to 1.5mm by traditional 1.0mm, is required with meeting big galvanic electricity output.
Data terminal 31, power supply terminal 32 and the inspection terminal 33 is L-shaped structure, and 2 tail end of glue core is equipped with coating
The vertical tails 21 namely the utility model of data terminal 31, power supply terminal 32 and inspection terminal 33 are applicable not only to direct plugging-in
2.0 interface of USB AF is also applied for 2.0 interface of bend cutting type USB AF.
