[0049] The Type-C input plug 10 is provided with an E-Mark chip module 15 which can automatically identify the voltage and current required by the electronic product to be charged; the E-Mark chip module 15 can read the properties of the wire 30, power transmission capability, data transmission capability, ID and other information using the PD fast charging protocol; thus, it can automatically identify the voltage and current required by the electronic product, and output a current of 2A-5A; and achieve a transmission power of 100W (20V / 5A) between the Type-C input plug 10 and the Type-C output plug 20.

[0050] The Type-C output plug 20 is mainly used to connect electronic devices, such as mobile phones, tablets and other power-demanding devices and data transmission devices.

The D+_1 pin 12 and the D-_1 pin 13 of the Type-C input plug 10 and the D+_1 pin 23 and the D-_1 pin 24 of the Type-C output plug 20 are connected in the manner of the PD fast charging protocol; the CC1 pin 22 of the Type-C input plug 10 and the CC1 pin 22 of the Type-C output plug 20 are connected in the manner of the QC fast charging protocol.

[0052] The above-mentioned E-Mark chip module 15 has a VCON1 pin 151, a VCON pin 152 and a CC1 pin 153, the VCON1 pin 151 is connected to the VCON1 pin 14 of the above-mentioned Type-C input plug 10, the VCON pin 152 is connected to the VCON pin 25 of the above-mentioned Type-C output plug 20, and the CC1 pin 153 is connected to the CC1 pin 11 of the Type-C input plug 10 and the CC1 pin 22 of the Type-C output plug 20 respectively.

[0053] The adapter plug 40 is a square-port plug (Lenovo square-port notebook) or a DC plug for a laptop computer 80. A plug interface 41 matching the plug end 21 of the Type-C output plug 20 is provided at the rear end of the adapter plug 40. The plug end 21 of the Type-C output plug 20 is detachably matched with the plug interface 41. A connecting strip 50 is provided between the adapter plug 40 and the Type-C output plug 20. One end of the connecting strip 50 is fixedly connected to the Type-C output plug 20, and the other end is movably connected to the adapter plug 40. The specific connection method is as follows: the adapter plug 40 includes a plug body 44 and an insulating sleeve 45 covering the outside of the plug body 44. A longitudinal groove 441 is provided on the side wall of the plug body 44 along its plugging direction. A notch 442 for the connecting strip 50 to pass through is provided at one end of the longitudinal groove 441 close to the plug interface 41. The connecting strip 50 is inserted through the notch 442. After passing through, it can be retracted and located in the longitudinal groove 441 (with the movement of the adapter plug 40, the connecting strip 50 can be retracted and slid in the longitudinal groove 441, and after the plug end 21 of the Type-C output plug 20 is matched with the plug interface 41 of the adapter plug 40, the connecting strip 50 is completely hidden in the longitudinal groove 441), and a limit block 51 is set at one end of the connecting strip 50 passing through the gap 442, and the limit block 51 is blocked on the inner side of the gap 442 to prevent the connecting strip 50 from escaping from the longitudinal groove 441; the above-mentioned insulating sleeve 45 covers the longitudinal groove 441, so that the connecting strip 50 is hidden. It should be noted that the connection method of the above-mentioned connecting strip 50 is as follows: Figure 5 , 6 The Chinese-port adapter plug is used as an example for demonstration, and the connection method of the connecting strip 50 on the DC adapter plug is the same.

[0054] The adapter plug 40 and the output plug 20 can also be matched in the following manner: the adapter plug 40 is matched with the output plug 20 in a magnetic attraction manner. Specifically, the opposing surfaces of the adapter plug 40 and the output plug 20 are designed to be magnetic attraction surfaces that can be attracted to each other. The adapter plug 40 and the output plug 20 are separably matched by attracting each other with the magnetic surfaces. Figure 7 , 8 As shown in FIG. 1 , the advantage of this design is that different adapter plugs 40 can be replaced as needed to meet the charging requirements of different electronic devices. In addition, the output plug 20 and the adapter plug 40 can retain the Type-C interface while having magnetic properties. Fig. 9 shown.

[0055] The adapter plug 40 is provided with a decoy chip module 42 (the decoy chip module 42 is a U2PD protocol chip, and CC1 and CC2 of the U2PD protocol chip support forward and reverse insertion), which can be used to decoy the voltage value. A voltage regulating resistor 43 for adjusting the decoy voltage value is provided outside the decoy chip module 42. The voltage regulating resistor 43 is connected to the decoy chip module 42, and the decoy voltage value can be adjusted to PD 9V, 12V, 15V or 20V through the voltage regulating resistor 43. For example, the decoy voltage is adjusted to 20V through the voltage regulating resistor 43, and the 20V voltage can be directly induced from the Type-C output plug 20 end for power supply through the U2PD protocol chip, and the U2PD protocol chip supports forward and reverse insertion.

[0056] The usage and principle of the data cable are as follows:

[0057] This product is a dual-purpose data cable that can be used as a Type-CFor Type-C fast charging cable with a built-in E-MAR chip module 11; it can also be used as a data cable that supports Lenovo square-port notebook power supply (an adapter plug 40 is added to the Type-C output plug, and the adapter plug 40 is a square-port output interface that can support Lenovo square-port notebook power supply).

[0060] 2: The E-Marker chip module 11 will pre-write the specifications, current carrying capacity, data transmission capacity and other parameters of the wire 30. The electronic device 70 can obtain the information of the wire 30 through the E-Marker chip module 11, so as to determine the power supply or data transmission mode to achieve the fastest power transmission under the premise of achieving protection effect.

[0061] 3: Circuit principle: The E-Marker chip module 11 is connected to the Type-C input plug 10, so that the electronic device 70 can use the PD fast charging protocol to read the properties of the cable: power transmission capability, data transmission capability, ID and other information, and match the required voltage, current and data transmission capability.

[0062] 4: The Type-C to Type-C fast charging cable part supports the PD / QC fast charging protocol. According to the input power of the charger 60 , it can support up to 100W device charging. It can power Type-C interface notebooks and low-power Type-C interface electronic devices 70 , solving the problem of fast charging of various electronic devices 70 .

[0063] 2: When the adapter plug 40 is matched with the plug end 21 of the Type-C output plug 20, it can be used as a data cable to support the power supply of Lenovo square-port notebooks.

[0064] The decoy chip module 42 sets the parameter value of the voltage regulating resistor 43 and directly decoys a voltage of 9V, 12V, 15V or 20V from the charger 60 end through the PD fast charging protocol for power supply (power-on is the mode of outputting 20V voltage), meeting the power supply requirements of Lenovo square port / DC port laptops.

[0065] The design focus of the present invention is to add a square port / DC adapter plug that can support laptop charging on the basis of a conventional fast charging data cable, so that the data cable can be used to charge low-power electronic devices such as mobile phones, mobile power supplies, 3C digital accessories, and laptops, thereby achieving the purpose of dual-purpose data cables and providing convenience for users to charge their electronic products.
