[0043] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0044] The following is for reference. Figures 1-7 The present application describes a charging cable 10 and a charging system according to embodiments thereof.

[0045] like Figure 1 and Figure 2 As shown, the charging cable 10 includes: a first connector 100, a branch connection 200, a second connector 300, and a cable 400.

[0046] One end of the cable 400 is provided with a first connector 100 and a branch connection part 200, and the other end of the cable 400 is provided with a second connector 300.

[0047] The second connector 300 is electrically connected to the first connector 100 and the branch connection part 200 via a cable 400. The charging power of the branch connection part 200 is greater than that of the first connector 100.

[0048] It should be noted that the first connector 100 can be a Lightning connector, and the second connector 300 can be a Type-C connector.

[0049] The relevant technology connects the Lightning connector to the charging device and the Type-C connector to the device being charged. However, due to the limitations of the Lightning charging protocol, the Lightning connector can only support a maximum charging power of 27W. When the Lightning connector supplies power to the Type-C connector, it cannot meet the fast charging power requirements of the device being charged, which are greater than 27W.

[0050] The above embodiments of this application can be implemented in the following two ways:

[0051] Firstly, when the charging cable 10 is configured to connect to the charging device via the first connector 100, the branch connection 200 is electrically connected to the charging device and supplies power to the device to be charged connected to the second connector 300.

[0052] In this embodiment, the input power of the branch connection part 200 is greater than the input power of the first connector 100. When the branch connection part 200 supplies power to the second connector 300, it can meet the fast charging power requirement of the device to be charged, which is greater than 27W.

[0053] For example, the branch connection 200 can be a POGOPIN structure, and the first contact group 210 of the POGOPIN structure is connected to the second contact group of the charging device 20, which can enable the second connector 300 to output 30 / 45W power.

[0054] It should be noted that the first connector 100 is connected to the charging device but does not supply power; instead, the charging device supplies power to the second connector 300 only through the branch connection 200. This is equivalent to bypassing the control circuit on the connector circuit board 112 of the first connector 100 and directly supplying power to the second connector 300.

[0055] Secondly, when the second connector 300 is connected to the charging device, the second connector 300 is electrically connected to the charging device and supplies power to the device to be charged connected to the first connector 100.

[0056] In this embodiment, if the device to be charged cannot be electrically connected to the second connector 300, that is, the interface type of the device to be charged does not match the type of the second connector 300 but matches the type of the first connector 100, the first connector 100 is electrically connected to the device to be charged and the second connector 300 is electrically connected to the charging device 20.

[0057] Under the limitations of the 100 charging protocol at the first connector, the maximum charging power supported for the device to be charged is 27W.

[0058] It should be noted that when the first connector 100 is electrically connected to the device to be charged, the branch connection part 200 can be installed on the device to be charged, but the branch connection part 200 does not supply power to the device to be charged. This can prevent the branch connection part 200 from being suspended and protect the electrical connection end of the branch connection part 200.

[0059] In summary, compared with related technologies, this application, by setting up a branch connection part 200 and making the input power of the branch connection part 200 greater than the input power of the first connector 100, can meet the fast charging power requirements of the device to be charged when the branch connection part 200 is electrically connected to the charging device 20, the second connector 300 is electrically connected to the device to be charged, and the branch connection part 200 supplies power to the second connector 300.

[0060] In actual operation, the output power of the second connector 300 when it is electrically connected to the device to be charged is greater than the output power of the first connector 100 when it is electrically connected to the device to be charged.

[0061] like Figure 3 As shown, in some embodiments, the branch connection portion 200 includes a first contact group 210 and a branch line core 220 correspondingly connected to the first contact group 210; the first contact group 210 is adapted to be correspondingly connected to a second contact group provided on the charging device 20.

[0062] The branch core 220 is connected to the conductive wire core in the cable 400, and is electrically connected to the second connector 300 through the conductive wire core.

[0063] It should be noted that the first contact group 210 includes multiple contacts, and the contacts of the second contact group on the charging device 20 correspond one-to-one with the contacts of the first contact group 210; the contacts of the first contact group 210 are connected one-to-one with the branch line core 220.

[0064] In specific design, the branch connection part 200 can be at least one of the following structural forms:

[0065] Firstly, such as Figure 2 and Figure 3 As shown, the first contact group 210 of the branch connection part 200 is provided on one side of the main body part 110 of the first connector 100.

[0066] In this embodiment, the first contact group 210 of the branch connection portion 200 can be arranged side by side with the main body portion 110 of the first connector 100, and the first contact group 210 of the branch connection portion 200 and the electrical connector 120 of the first connector 100 are oriented in the same direction.

[0067] Secondly, the branch connection part 200 is provided on the main body part 110 of the first connector 100, and the first contact group 210 of the branch connection part 200 is provided on the end face of the main body part 110 of the first connector 100 (not shown).

[0068] In this embodiment, the end face of the main body portion 110 of the first connector 100 is the end face of the main body portion 110 of the first connector 100 facing the electrical connector 120 of the first connector 100, and the first contact group 210 of the branch connection portion 200 is aligned with the electrical connector 120 of the first connector 100.

[0069] It should be noted that the branch connection part 200 can be integrally formed with the main body part 110 of the first connector 100, or it can be separately set from the main body part 110 of the first connector 100. This embodiment does not impose any restrictions.

[0070] like Figure 2 and Figure 3 As shown, in actual implementation, the main body 110 includes: a covering layer 111 and a connector circuit board 112.

[0071] The covering layer 111 is sleeved on the outside of the connector circuit board 112, and the first contact group 210 protrudes from the outside of the covering layer 111; the end of the branch line core 220 connected to the wire core of the cable 400 is located on the side of the connector circuit board 112 away from the electrical connector of the first connector 100; the electrical connector 120 of the first connector 100 is electrically connected to the connector circuit board 112, and is electrically connected to the second connector 300 through the connector circuit board 112.

[0072] In actual implementation, the first connector 100 includes a first connector, and the second connector 300 includes a second connector.

[0073] The first connector is connected to the second connector. The first connector is a Lightning connector, and the second connector is a USB Type-C connector.

[0074] like Figures 4-7 As shown, this application also proposes a charging system including the charging cable 10 of any of the above embodiments.

[0075] The charging device 20 is provided with a branch output section 21, a first female connector 22 and a second female connector 23; the charging device 20 is adapted to be electrically connected to the branch connection section 200 through the branch output section 21.

[0076] The charging device 20 is adapted to be fixedly connected to the first connector 100 via the first female connector 22; the charging device 20 is adapted to be electrically connected to the second connector 300 via the second female connector 23.

[0077] The above embodiments of this application can be implemented in the following two ways:

[0078] First, the branch connection part 200 at one end of the charging cable 10 is electrically connected to the branch output part 21 of the charging device 20, and the second connector 300 at the other end of the charging cable 10 is electrically connected to the device to be charged.

[0079] In this embodiment, when the branch connection part 200 is a POGOPIN structure, the first contact group 210 of the POGOPIN structure is connected to the second contact group of the charging device 20, which can enable the second connector 300 to output 30 / 45W power.

[0080] Secondly, if the device to be charged cannot be electrically connected to the second connector 300, that is, the interface type of the device to be charged does not match the type of the second connector 300, but matches the type of the first connector 100, the first connector 100 at one end of the charging cable 10 is electrically connected to the device to be charged, and the second connector 300 is electrically connected to the second female connector 23 of the charging device 20.

[0081] In actual operation, when the branch connection 200 is electrically connected to the charging device 20, the first connector 100 and the first female connector 22 are not electrically connected. That is, the first connector 100 is physically installed on the first female connector 22 of the charging device 20, but does not supply power. The first connector 100 and the first female connector 22 do not form an electrical path, thus allowing the charging device 20 to supply power to the second connector 300 only through the branch connection 200. This is equivalent to bypassing the control circuit on the connector circuit board 112 of the first connector 100 and directly supplying power to the second connector 300.

[0082] like Figures 4-6 As shown, in some embodiments, the outer wall surface of the charging device 20 is provided with a groove 24 that mates with the branch connection portion 200; the branch output portion 21 is provided in the groove 24.

[0083] The groove 24 on the outer wall of the charging device 20 provides support for the insertion of the branch connection part 200, so as to facilitate a more stable connection between the branch connection part 200 and the branch output part 21.

[0084] In actual implementation, the branch output section 21 includes a second contact group, and the branch connection section 200 includes a first contact group 210, which is adapted to be connected to the second contact group.

[0085] The second contact group is arranged side by side on the bottom surface of the groove 24 of the charging device 20, and the second contact group is correspondingly arranged with the first contact group 210.

[0086] In actual operation, the first contact group 210 includes a first contact, a second contact, a third contact, a fourth contact, and a fifth contact; the second contact group includes a sixth contact, a seventh contact, an eighth contact, a ninth contact, and a tenth contact.

[0087] The first contact is connected to the sixth contact, the second contact is connected to the seventh contact, the third contact is connected to the eighth contact, the fourth contact is connected to the ninth contact, and the fifth contact is connected to the tenth contact.

[0088] like Figure 7 As shown, in some embodiments, the charging device 20 includes: a power module 25, a main control chip 26, and an output module 27 that are electrically connected to each other; the output module 27 includes: a power positive terminal, a power negative terminal, a data positive terminal, a data negative terminal, and a protocol communication terminal.

[0089] The positive power terminal of the output module 27 is electrically connected to the sixth contact and the first pin of the second female connector 23; the negative power terminal of the output module 27 is electrically connected to the seventh contact and the second pin of the second female connector 23; the positive data terminal of the output module 27 is electrically connected to the eighth contact and the third pin of the second female connector 23; the negative data terminal of the output module 27 is electrically connected to the ninth contact and the fourth pin of the second female connector 23; and the protocol communication terminal of the output module 27 is electrically connected to the tenth contact and the fifth pin of the second female connector 23.

[0090] The power module 25 is responsible for converting the DC or AC power supplied by an external power source into a stable DC power suitable for charging output. In actual implementation, the power module 25 may include a battery or an AC-to-DC module; the output module 27 may include a DC-to-DC module.

[0091] The main control chip 26 is responsible for the management and control of the entire charging system, including detecting charging needs, coordinating charging protocols, and adjusting output parameters. For example, by communicating with a protocol communication terminal (such as the SBU port), it can identify whether the device supports fast charging protocols (such as USB Power Delivery) and adjust the power output parameters (voltage and current) according to the needs of the device being charged.

[0092] The output module 27 is responsible for adjusting the DC power transmitted by the power module 25 to the DC power required by the device to be charged according to the power output parameters adjusted by the main control chip 26, and then transmitting it to the device to be charged through the charging cable 10.

[0093] The positive terminal of the power supply of the output module 27 is used to transmit the current from the power supply module 25 to the device to be charged, thereby powering the device. The negative terminal of the power supply of the output module 27 is used to allow the current output by the power supply module 25 to flow back, forming a closed loop.

[0094] The positive terminal of output module 27 transmits the positive signal of data, providing an uplink data channel for communication between devices. The negative terminal of output module 27 transmits the negative signal of data, serving as a return channel for data transmission, forming a complete data transmission path with the positive terminal.

[0095] The protocol communication terminal of output module 27 is responsible for the negotiation and communication of the charging protocol between the charging device and the device to be charged.

[0096] It should be noted that, in this embodiment, the first pin of the second female connector 23 is the VBUS pin; the second pin of the second female connector 23 is the GND pin; the third pin of the second female connector 23 is the positive data pin D+; the fourth pin of the second female connector 23 is the negative data pin D-; and the fifth pin of the second female connector 23 is the protocol communication pins SBU1 and SBU2.
