Description
Technical field
The utility model relates to a kind of terminal charge technology, especially a kind of USB-C connector turns terminal charge interface arrangement.
Background technique
Currently based on USBTYPE-C (USB-C) interface and the terminal device that is applicable in USB PD charge protocol it is more and more, phase
The charger based on USB PD agreement answered is also more and more.Mainstream is the USB-C interface charger of 45W, 65W at present, such as
Apple macbookpro standard configuration charger is 65W.But traditional laptop, printer, desktop computer or rechargeable LED lamp etc.
Charger does not support newest USB PD agreement to charge, and the charging interface of most all criteria of right and wrongs, while adapter is heavy
It is and big, it has not been convenient to which that user carries, such as the big round end charging connector of thinkpad.
Summary of the invention
The purpose of this utility model is to provide a kind of USB-C connectors to turn terminal charge interface arrangement, so that traditional pen
Remember that this charger is also applied for USB-C charger.
A kind of USB-C connector turns common computer charging interface device, including main body, is set to the USB-C of one end face of main body
If interface, the common computer charging interface for being set to main body other end, the dry circuit for being set to body interior；Wherein circuit packet
Power circuit, protection circuit, USB PD protocol circuit, control circuit are included, power circuit is positive and negative on USB-C interface for connecting
The positive and negative anodes of pole contact and common computer charging interface, protection circuit are set on power circuit, set in USB PD protocol circuit
It sets USB PD agreement and is connect respectively with common computer charging interface and power circuit, control circuit is for controlling power circuit
Connection or disconnection.
The utility model compared with prior art, has the following advantages that：(1) by traditional notebook computer or other terminals
Charging connector links together with the adapter with USB PD agreement, and power increases；(2) device uses USB PD agreement,
Volume is smaller compared with traditional notebook computer or other terminal adapters, easy to carry；(3) the device charging end is connect using USB-C
Mouthful, with most data lines matchings on the market, solve inconsistent confusion of powering.
The utility model is further described with reference to the accompanying drawings of the specification
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model interface is USB-C female.
Fig. 2 is the structural schematic diagram that the utility model interface is USB-C male connector.
Fig. 3 is the principles of the present invention schematic diagram.
Specific embodiment
USB Power Delivery Specification (USB PD) is one can be supplied to using USB interface realization
The standard of 100W electric power.The utility model is based on the agreement and makes a kind of switching device, and conventional terminal disunity type may be implemented
The problem of number adapter and adapter can not carry out fast charge.
In conjunction with Fig. 1, Fig. 2, Fig. 3, a kind of USB-C connector turns terminal charge interface arrangement, including main body 1, is set to main body 1
If the USB-C interface 2 of an end face, is set to inside main body 1 the common computer charging interface 3 for being set to 1 other end of main body
Dry circuit.Circuit includes power circuit, protection circuit, USB PD protocol circuit, control circuit.Power circuit is suitable for converting
Orchestration power supply to the circuit of common notebook computer interface, fill by the positive and negative anodes contact and common computer connected on USB-C interface 2
The positive and negative anodes of electrical interface 3.Protection circuit is set on power circuit, and overvoltage crowbar, overcurrent protection electric current, short can be set
Protect one of circuit or several in road.USB PD agreement is set in USB PD protocol circuit and is charged respectively with common computer
Interface is connected with power circuit, triggers the circuit of USB PD agreement, and user and USB PD protocol adaptor carry out protocol, produce
Raw voltage.Control circuit is used for the opening and closing of control access
USB-C interface 2 can be USB-C female described in Fig. 1, or male connector shown in Fig. 2.
Circuit further includes the indicating circuit being connected with control circuit.
Specifically, the core chips of PD protocol circuit can choose FUSE302, and the core chips of control circuit can choose
AT89C2051, controls the agreement flowchart process of USE302, and agreement is to suitable supply voltage and electric current, built-in over-voltage/overcurrent
Deng protection circuit, uplink and downlink equipment is protected not to be damaged.
