Detailed Description

Conventional data line devices typically have a USB connector at one end and various communication connectors at the other end. Taking the data line of the mobile phone as an example, one end of the data line is a USB connector, and the other end of the data line can be a lighting connector commonly used by apple cell phones, a Mircro connector commonly used by cell phones such as huashi and the like, a TypeC connector which appears recently, and the like.

And the current TypeC connector has the advantages of stable performance, strong compatibility, fast data transmission, fast charging, difficult damage, capability of being inserted into the front and the back, and the like, so that the TypeC connector is gradually and widely applied to various electronic devices. For example, in the latest computer products, it is gradually appearing to replace the original USB interface with a TypeC interface; in the power plug of some mobile phone devices, the interface of the data line device is also changed from a USB connector to a TypeC interface. However, the devices with the TypeC interfaces replaced can only be used by the matched data lines, and the data lines sold in the market are still USB connectors, so that if the originally matched data lines are lost or forgotten to be carried in the process of using the electronic devices, the charging of the mobile phone or the connection of the mobile phone and the computer and other devices cannot be realized, and great inconvenience is brought to the use of the electronic devices by the users.

Therefore, the multi-joint data line equipment is provided in the application, the connection between the equipment with the TypeC interface and the equipment with other various common interfaces can be realized, the use of the electronic equipment by a user is facilitated, and the use experience of the user is improved.

In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a multi-tap data line device provided in an embodiment of the present application, where the device may include:

a data line 1;

the first end of the data line 1 is provided with an input terminal TypeC connector 2 used for being connected with a TypeC interface of the electronic equipment, and the second end of the data line is provided with a conversion connector 3 electrically connected with a pin of the input terminal TypeC connector 2;

and the device also comprises a lightning connector 4, a TypeC connector 5 and a Mirro connector 6 which can be connected with the conversion connector 3 and are electrically connected with pins of the TypeC interface through the conversion connector 3 and the TypeC interface respectively.

For the adapter 3 arranged at the second end of the data line 1, three branches can be arranged, and each branch is fixedly connected with a lightning connector 4, a TypeC connector 5 and a Mircro connector 6; the lightning connector 4, the type c connector 5 and the micro connector 6 may be detachably connected to the adapter 3, and when a user needs to use any one of the lightning connector 4, the type c connector 5 and the micro connector 6, one of the connectors may be connected to the adapter 3, and when a different connector needs to be used, the connector may be replaced. For example, only one adapter 3 is provided at the second end of the data line 1, and the lightning connector 4, the TypeC connector 5, and the Mircro connector 6 are alternatively connected to the adapter 3.

Alternatively, the crossover sub 3 may be magnetically connected to the lightning sub 4, the type c sub 5, and the Mircro sub 6 respectively, for example, permanent magnets may be disposed on the crossover sub 3 and the lightning sub 4, the type c sub 5, and the Mircro sub 6, and the magnets on the crossover sub 3 and the lightning sub 4, the type c sub 5, and the Mircro sub 6 are opposite in magnetism, so as to increase the magnetic force between the crossover sub 3 and the lightning sub 4, the type c sub 5, and the Mircro sub 6 to the maximum extent, so that the crossover sub 3 and the lightning sub 4, the type c sub 5, and the Mircro sub 6 are connected to each other by attraction; of course, the technical solution of the present application may be realized by merely providing the magnet on the adapter 3 and providing the metal on the lightning connector 4, the TypeC connector 5, and the Mircro connector 6.

Of course, in this application, the adaptor 3 and the lightning joint 4, the TypeC joint 5, and the Mircro joint 6 may be set to be in a structure that they can be plugged into or pulled out of each other, so as to realize detachable connection between the lightning joint 4, the TypeC joint 5, and the Mircro joint 6 and the adaptor 3, respectively.

In addition, in order to avoid the lightning connector 4, the TypeC connector 5 and the Mirro connector 6 from being lost, movable connectors can be arranged on the adapter connector 3 and the lightning connector 4, the TypeC connector 5 and the Mirro connector 6 respectively. For example, the adaptor connector, the lightning connector 4, the TypeC connector 5, and the Mirro connector 6 are respectively provided with a collar to be sleeved on the data line, so that the lightning connector 4, the TypeC connector 5, and the Mirro connector 6 are prevented from being lost when not needed.

As shown in fig. 1, an input terminal TypeC connector 2 is arranged at a first end of a data line 1, so that the first end of the data line 1 can be connected with a power socket with a TypeC interface, a mobile power supply, a computer and other devices; and the second end of the data line 1 is provided with a lightning connector 4, a type c connector 5 and a micro connector 6, so that the second end of the data line 1 can be connected with a mobile phone device, a Pad device or other devices with the lightning connector 4, the type c connector 5 or the micro connector 6. That is to say, the data line 1 one end that provides in this embodiment can with the equipment such as power, the computer that has the type C interface, the other end can be connected the electronic equipment that has various different communication connectors, and then realize having the connection of the equipment of type C interface and various electronic equipment that do not use communication interface, realized to a great extent that the user uses electronic equipment's convenience, promote the user and use the experience of electronic equipment.

There are differences in the wiring pins for the lightning 4, TypeC 5 and Mircro 6 connectors. In order to connect three different connectors to the same adapter, as shown in fig. 2 to 4, fig. 2 is a schematic diagram of a lightning connector provided in an embodiment of the present application, fig. 3 is a schematic diagram of a TypeC connector provided in an embodiment of the present application, and fig. 4 is a schematic diagram of a Mircro connector provided in an embodiment of the present application.

The wiring pins for the end where the lightning connector 4 and the converting connector 3 are connected can be sequentially arranged as follows:

an ID0 pin, an NC pin, a CC1 pin, a D + pin, a D-pin, a Vout pin, and a GND pin.

The wiring pin of the one end that is connected to typeC joint 5 and crossover sub 3 can set gradually:

an NC pin, a first Vout pin, a CC1 pin, a D + pin, a D-pin, a second Vout pin, and a GND pin.

The connection pins to the end where the Mircro connector 6 and the adapter connector 3 are connected can be arranged in sequence:

The pins for the Mircro connectors and the pins for the TypeC connectors are the same. The data line 1 to which the lightning connector 4 is connected is generally used for connecting a power supply to a device such as a mobile phone or an iPad, or a device such as a computer. If the electronic terminal equipment such as the apple cell phone and the iPad is connected with other equipment through the data line 1, the subsequent operation can be realized by firstly sending out an authentication signal through the equipment such as the apple cell phone and the iPad and then finishing authentication based on the authentication chip U1. Therefore, the lightning connector 4 needs to be provided with an ID0 pin for transmitting an authentication signal, so that the apple brand electronic terminal device can output an authentication signal through the ID0 pin, and subsequent communication connection can be performed after the authentication is passed.

While the conventional type c connector 5 and the Mircro connector 6 do not need to be provided with the ID0 pin, in order to ensure the consistency of the number of the three connector pins, the NC pin may be provided in the pin of the type c connector 3 and the Mircro connector 6 corresponding to the ID0 pin position of the lightning connector 4.

In addition, the TypeC connector 5 and the Mirro connector 6 have one more Vout pin relative to the lightning connector 4, so that the accessed current can be shunted, and the electronic equipment is protected.

Further, a protocol resistor R0 is further connected to the CC1 pins of the Mircro connector 6 and the lightning connector 4. The protocol resistor R0 may be sized to be about 5.1K Ω and may be 10% floating around 5.1K Ω.

It should be noted that, the data line provided in the present application is generally applied to charging an electronic terminal device such as a mobile phone, or to communicatively connect two different electronic terminal devices. When the data line 1 is used to connect a charger to an electronic terminal, i.e. to charge the electronic terminal, the charging voltage output via the data line is generally relatively large, typically 9V to 20V, because the charger with the TypeC interface is used to charge the electronic terminal more quickly.

Then, after the data line device is connected to the charger first, if the connector of the data line device, which needs to be connected to the electronic terminal device, is not connected to the electronic terminal device yet and is in a high voltage state, the electronic terminal device may be damaged or even burned due to an excessive voltage at the moment of connecting the connector of the data line device.

For this reason, a charging protocol exists in the charger with the TypeC interface, and when the charger detects that the other end of the data line device is connected with the electronic terminal device through the data line device, the charger starts to access voltage to the electronic terminal device through the data line device. The process of identifying whether to connect the electronic terminal equipment is judged by whether the connector connected with the data line device and the electronic terminal equipment is connected to the protocol resistor R0 through the CC1 pin of the connector.

For electronic terminal equipment such as a mobile phone with a TypeC interface, a protocol resistor R0 communicated with a CC1 pin of the TypeC connector 5 is arranged in the electronic terminal equipment, so that the problem that when a data line is connected with the electronic terminal equipment with the TypeC interface, the instantaneous voltage is too high to damage when a charger is connected can be avoided.

However, the electronic terminal device connected to the Mircro connector 6 and the lightning connector 4 does not have the protocol resistor R0 therein, so that the effect of ensuring the safety of the electronic device can be achieved. A protocol resistor R0 may be further connected to the CC1 pins of the Mircro connector 6 and the lightning connector 4, and one end of the protocol resistor R0 is connected to the CC1 pin, and the other end is grounded.

In practical applications, since the lightning connector 4 and the Mircro connector 6 can be detached from the adapter 3, the lightning connector 4 and the Mircro connector 6 can be directly kept on the charging interface of the electronic terminal device, and when the electronic terminal device needs to be charged, the lightning connector 4 and the Mircro connector 6 are directly connected to the adapter 3 when being connected to the electronic terminal device.

Based on the above discussion, to realize the integration application between three different connectors, it is necessary to provide a circuit capable of simultaneously satisfying the operation of the three connectors on the circuit board of the adapter 3.

In another alternative embodiment of the present application, as shown in fig. 5, fig. 5 is a schematic circuit structure diagram of the crossover connector provided in the embodiment of the present application. The crossover joint 3 may include:

first contacts P1 for connection to the pins of lightning 4, TypeC 5 and Mircro 6 connectors, respectively;

a second contact P2 for connection to a pin of an input TypeC header 2;

the MCU control chip U2; an authentication chip U1 and a switch circuit 7.

Referring to fig. 2 to 5, in order to be able to be electrically connected with the lightning connector 4, the TypeC connector 5 and the Mircro connector 6 in a matched manner, the first contact P1 connectable with the lightning connector 4, the TypeC connector 5 and the Mircro connector 6 in the conversion connector 3 may be sequentially set as an ID0 pin, a Vout pin, a CC1 pin, a D + pin, a D-pin, a Vout pin and a GND pin, and the two Vout pins of the first contact P1 are connected with each other.

The second contact P2 is typically in communication with a charger, or other electronic device. As shown in fig. 6, fig. 6 is a pin diagram of the second contact provided in the embodiment of the present application. For the second contact P2, there are many pins, but since the present application mainly relates to several pins corresponding to the first contact P1, only the GND pin, the D + pin, the D-pin, the CC1 pin, and the Vin pin of the second contact are shown in fig. 5, and details of other pins are not repeated.

Referring to fig. 5, the GND pin, the D + pin, the D-pin, and the CC1 pin for the first contact P1 and the second contact P2 may be directly connected in a one-to-one correspondence, respectively, while the Vin pin of the second contact P2 is connected to the Vout pin of the first contact P1 for supplying power to the Vout pin of the first contact P1.

As described above, when the second contact P2 and the charger are connected, if the charger detects that the CC1 pin of the first contact P1 is grounded through the protocol resistor R0 through the CC1 pin of the second contact P2, a charging voltage is input to the Vout pin of the first contact P1 through the Vin pin of the second contact P2, and the charging voltage is gradually increased from a small value to a specific high charging voltage, which may be generally 9V to 20V; otherwise, the Vin pin of the second contact P2 always inputs no voltage signal.

Further, as described above, for the apple brand electronic product, whether the Vin pin of the second contact P2 and the Vout pin of the first contact P1 can be connected in communication or not requires the electronic device accessed through the lingering connector 4 at the second end of the data line to be authenticated and then can be connected in communication. The charger or other non-matching electronic devices generally do not have the authentication function, so that the electronic products of the apple brand cannot be connected with the chargers or electronic terminal devices of other brands. For this purpose, in the present application, an authentication chip U1 is further disposed in the circuit board of the data line, and the Vin pin of the second contact P2 and the Vout pin of the first contact P1 are electrically connected through the intermediate switch circuit 7, and when the authentication is passed and the switch circuit 7 is turned on, the Vin pin of the second contact P2 and the Vout pin of the first contact P1 are turned on, and the electronic device connected to the first end of the data line 1 and the electronic device connected to the second end can be connected in signal communication through the Vin pin and the Vout pin.

Therefore, in an alternative embodiment of the present application, referring to fig. 5, the switching circuit may further include:

the wiring pins of the authentication chip U1 are respectively connected with the ID0 pin of the first contact P1 and the first input end of the MCU control chip U2, and the first output end of the MCU control chip U2 is connected with the control input end of the switch circuit 7. The input terminal of the switch circuit 7 is connected to the Vin pin of the second contact P2, and the output terminal of the switch circuit 7 is connected to the Vout pin of the first contact P1.

The authentication chip U1 is used for controlling the switch circuit 7 to connect the Vin pin of the second contact P2 to input a communication signal to the Vout pin of the first contact P1 through the MCU control chip U2 when the correct authentication signal is input to the ID0 pin of the first contact P1 through the pin of the lightning connector 4.

Referring to fig. 5, the first connection pin of the authentication chip U1 is connected to the ID0 pin of the first contact P1 and the PA1/ICSPDAT pin of the MCU control chip U2, the second connection pin of the authentication chip U1 is grounded through the second capacitor C2, and the third connection pin is directly grounded. The first input terminal of the MCU control chip U2 may be a PA1/ICSPDAT pin, and the first output terminal of the MCU control chip U2 may be a PA2/TOCKI/INT pin.

In addition, no matter which of the lightning connector 4, the TypeC connector 5 and the Mircro connector 6 is connected to the first contact P1, as long as the second contact P2 is connected to the charging power source, the switch circuit 7 is kept closed in the initial state and charges the electronic terminal device connected to the first contact P1.

When the first contact P1 is connected to a lightning connector, as shown in fig. 5, the ID0 pin of the first contact P1 is connected to the ID 1 pin of the authentication chip U1 and the PA1/ICSPDAT pin of the U2 at the same time, when the lightning connector 4 pin inputs an authentication signal to the ID0 pin of the first contact P1, the MCU control chip U2 controls the switch circuit 7 to disconnect the Vin pin of the second contact P2 from the Vout pin of the first contact P1, and the authentication chip U1 authenticates the authentication signal, and when the authentication chip U1 confirms that the authentication signal is correct, the MCU control chip U2 controls the switch circuit 7 to connect the Vin pin of the second contact P2 to the Vout pin of the first contact P1 again, thereby charging the electronic terminal device connected to the first contact P1.

When the first contact point P1 is accessed through one of the TypeC connector 5 and the Mircro connector 6, the electronic terminal device accessed through the TypeC connector 5 and the Mircro connector 6 does not have the authentication signal input through the ID0 terminal. At this time, the MCU control chip U2 does not need to control the switch circuit 7 to be turned off, and only the switch circuit 7 is kept closed to charge the electronic terminal device connected to the first contact P1, so that different electronic terminal devices can use the data line device of the present application.

The structure of the switching circuit will be described in detail below in a specific embodiment, and with reference to fig. 5, the switching circuit 7 may include:

the transistor comprises a first MOS transistor Q1, a second MOS transistor Q2, a triode Q3, a first resistor R1, a second resistor R2 and a first diode D1;

the cathode of the first diode D1, the second end of the second resistor R2, the source of the first MOS transistor Q1, the source of the second MOS transistor Q2 and the first end of the first resistor R1 are all connected with the Vin pin of the second contact P2;

the drain of the first MOS transistor Q1, the drain of the second MOS transistor Q2, and the second terminal of the first resistor R1 are connected to the Vout pin of the first contact P1.

In fig. 5, the transistor Q3 is an NPN transistor, and the first MOS transistor Q1 and the second MOS transistor Q2 are both PMOS transistors. It can be understood that the transistor and the MOS transistor are used as the switching device, and in practical applications, the NPN transistor, the PNP transistor, the NMOS transistor, and the MMOS transistor may be replaced with each other, and only the magnitude of the electrical signal for turning off and on needs to be adaptively adjusted, so that specific types of the transistor Q3, the first MOS transistor Q1, and the second MOS transistor Q2 are not specifically limited in this application.

For convenience of description, in this embodiment, the transistor Q3 is considered to be an NPN-type transistor by default, and the first MOS transistor Q1 and the second MOS transistor Q2 are both PMOS transistors.

When the MCU control chip U2 inputs a low-level control signal to the base of the transistor Q3 of the switch circuit 7, the transistor Q3 is turned on, so that the first MOS transistor Q1 and the second MOS transistor Q2 are turned on, and the Vin pin of the second contact P2 and the Vout pin of the first contact P1, which are connected to the switch circuit 7, are turned on.

Further, considering that the Vin pin of the second contact P2 may be a power supply device such as a charger, the current signal received by the Vin pin may be relatively large, which causes a large current signal to be received at the instant when the Vout pin of the first contact P1 and the Vin pin of the second contact P2 are turned on, resulting in damage to the electronic device received by the second end of the data line 1. For this purpose, a first resistor R1 may be further connected in parallel between the input and output of the switching circuit 7. Referring to fig. 2, both ends of the first resistor R1 are connected to a Vin pin of the second contact P2 and a Vout pin of the first contact P1, respectively.

Before the switching circuit 7 is connected with the Vin pin of the second contact P2 and the Vout pin of the first contact P1 through the transistor Q3, the first MOS transistor Q1 and the second MOS transistor Q2, the conduction of current is reduced through the first resistor R1 with a large resistance value, so that even if the current connected to the Vout pin of the first contact P1 is increased due to the connection of the transistor Q3, the first MOS transistor Q1 and the second MOS transistor Q2, the problem of damage to electronic equipment caused by sudden increase of current can be avoided.

Optionally, in another optional embodiment of the present application, a power supply circuit 8 for supplying power to the MCU control chip U2 may be further included, where the power supply circuit 8 may include:

a third resistor R3, a second diode D2, a third diode D3,

the cathode of the second diode D2 and the cathode of the third diode D3 are both connected with the VDD pin of the MCU control chip U2, the anode of the second diode D2 is connected with the first end of a third resistor R3, and the second end of the third resistor R3 is connected with the second end of a first resistor R1; the anode of the third diode D3 is grounded.

As shown in fig. 5, when the second contact P2 is connected to a powered device, the current of the Vin pin of the second contact P2 flows to the third resistor R3 through the first resistor R1, and then flows to the VDD pin of the MCU control chip U2 through the second diode D2, and the second diode D2 protects the MCU control chip U2 when the MCU control chip U2 is powered off.

In another optional embodiment of the present application, the power indication circuit 9 may further include a light emitting diode D4 and a fourth resistor R4;

The power indicator circuit 9 is connected to a Vin pin of the second contact P2, that is, a Vin pin, and when the Vin pin is connected to a voltage, the light emitting diode D4 is turned on to emit light, so that a user can determine that the data line device is powered on according to the light emitted by the light emitting diode D4.
