[0019] Hereinafter, embodiments will be described in detail with reference to the attached drawings. In the description with reference to the attached drawings, identical components are given the same reference numeral regardless of the drawing number, and redundant descriptions thereof will be omitted.

[0020] FIG. 1 is a schematic diagram of a cable assembly (300) and peripheral devices (e.g., electronic device (101) of FIG. 1) according to various embodiments.

[0021] The cable assembly (300) may include a cable (340), a first connector (310) connected to one side of the cable (340), and a second connector (320) and a third connector (330) respectively connected to the other side of the cable (340).

[0022] The first connector (310) can be connected to an electronic device (101). The second connector (320) can be connected to a power supply unit (200). For example, the power supply unit (200) may be a charger that supports fast charging. For example, the power supply unit (200) may be a power supply unit (PD source) that uses USB Type C power delivery (PD) technology. The third connector (330) can be connected to an additional electronic device (1011) (e.g., the electronic device (1011) of FIG. 1). The additional electronic device (1011) may be an electronic device (101) of the same type as the electronic device (101) or an electronic device of a different type.

[0023] Referring again to FIG. 1, the cable assembly (300) includes a second connector (320) and a third connector (330), thereby allowing the electronic device (101) connected to the first connector (310) to be simultaneously connected to the power supply device (200) and an additional electronic device (1011).

[0024] For example, even if an additional electronic device (1011) connected to the electronic device (101) via a cable assembly (300) does not support high-speed charging, the electronic device (101) can be high-speed charged via a power supply device (200) connected via a second connector (320).

[0025] For example, the cable assembly (300) can enable the electronic device (101) to communicate data with an additional electronic device (1011) while simultaneously enabling the electronic device (101) to be charged at high speed.

[0026] According to various embodiments, the cable (340) of the cable assembly (300) may include one or more sub-cables (340). For example, the cable (340) may include a first sub-cable (341) and a second sub-cable (342). For example, one or more wires (not shown) connecting a first connector (310) and a second connector (320) may be disposed in the first sub-cable (341), and one or more wires connecting a first connector (310) and a third connector (330) may be disposed in the second sub-cable (342). Alternatively, the wires connecting the first connector (310) and the second connector (320) and the wires connecting the first connector (310) and the third connector (330) may be integrated and covered by a single cable (340). Alternatively, for example, the first sub-cable (341) and the second sub-cable (342) may be covered externally with a reinforcing sheath.

[0027] Alternatively, the cable (340) may be branched at any point to form two sub-cables (e.g., the first sub-cable (341) and the second sub-cable (342) of FIG. 1).

[0028] Meanwhile, the length of the cable (340) may vary. For example, the length of the cable (340) may be 1.5 m or less.

[0029] Additionally, the thickness or cross-sectional area of ​​the cable (340) may vary. For example, the thickness or cross-sectional area of ​​the cable (340) may be specified to carry more than 65 W of power.

[0030] The first connector (310), the second connector (320), and the third connector (330) may be in the form of plugs that can be inserted into a receptacle provided in an electronic device (101) or a power supply device (200).

[0031] The first connector (310), the second connector (320), and the third connector (330) may include pins for various purposes.

[0032] For example, the first connector (310), the second connector (320), and the third connector (330) may be USB Type C connectors. In this regard, FIG. 2 is a drawing showing the pins constituting the USB Type C connector of the cable assembly (300) according to various embodiments.

[0033] Referring to FIG. 2, the first connector (310) of the cable assembly (300) according to various embodiments may be a USB Type C connector, and the first connector (310) may have 24 pins.

[0034] For example, the first connector (310) may include a first connector (310) CC (configuration channel) pin (314). The first connector CC pin (314) can detect the mounting status of the power supply (200) and whether high-speed charging is possible when connected to the power supply (200) using a USB Type C connector.

[0035] For example, the first connector (310) may include a first connector power pin (311). The first connector power pin (311) is indicated as VBUS in the drawing. As illustrated, there may be multiple first connector power pins (311). The first connector power pin (311) can transmit power to an electronic device (e.g., electronic device (101) of FIG. 1) through a pin that contacts the first connector power pin (311) of the receptacle into which the first connector (310) is inserted.

[0036] For example, the first connector (310) may include a first connector data transmission pin (312). The first connector data transmission pin (312) may be multiple. For example, the first connector data transmission pin (312) may be labeled as a D+ pin and / or a D- pin. The D+ pin and / or the D- pin can perform USB 2.0 interface communication. Additionally, the first connector data transmission pin (312) may further include pins labeled as TX1+, TX1-, TX2+, TX2-, RX1+, RX1-, RX2+, and RX2- pins. These can form a high-speed data path. Meanwhile, the pin names may be expressed in the form where SS is attached to TX and / or RX, i.e., SSTX and / or SSRX, where SS stands for super speed and TX and SSTX can be understood as referring to the same pin. This is the same in all drawings below.

[0037] For example, the first connector (310) may include a first connector ground pin (313) for ground, which may be indicated as a GND pin.

[0038] For example, the first connector (310) may include a first connector auxiliary pin. For example, the first connector (310) auxiliary pin may further include an SBU2 pin and a VCONN pin.

[0039] The above description regarding the pins that the first connector (310) may include may be applied equally to the second connector (e.g., the second connector (320) of FIG. 1) and / or the third connector (e.g., the third connector (330) of FIG. 1). For example, the second connector may include a second connector power pin (e.g., the second connector power pin (321) of FIG. 4), a second connector data transmission pin (e.g., the second connector data transmission pin (322) of FIG. 5), a second connector ground pin (e.g., the second connector ground pin (323) of FIG. 4), and a second connector auxiliary pin, and the third connector may include a third connector power pin (e.g., the third connector power pin (331) of FIG. 4), a third connector data transmission pin (e.g., the third connector data transmission pin (332) of FIG. 6), a third connector ground pin (e.g., the third connector ground pin (333) of FIG. 4), and a third connector auxiliary pin.

[0040] Meanwhile, referring to FIG. 3, the third connector (330) may be a Type A connector. The third connector (330), which may be a Type A connector, may include nine pins. In this regard, FIG. 3 is a drawing showing the pins constituting the Type A connector of the cable assembly (300) according to various embodiments.

[0041] For example, the third connector (330) may include a third connector power pin (331), which may be indicated as a VBUS pin.

[0042] For example, the third connector (330) may include a third connector data transmission pin (332). The third connector data transmission pin (332) may be multiple. For example, the third connector data transmission pin (332) may be labeled as a D+ pin and / or a D- pin. The D+ pin and / or the D- pin can perform USB 2.0 interface communication. Additionally, the third connector data transmission pin (332) may further include pins labeled as SSRX-, SSRX+, SSTX-, and SSTX+ pins. These can form a high-speed data path and can perform USB 3.1 interface communication through them.

[0043] For example, the third connector (330) may include a third connector ground pin (333) for ground, which may be indicated as a GND pin.

[0044] Meanwhile, the first connector, the second connector, and the third connector (330) may be modified forms of the type C connector or type A connector described above.

[0045] For example, the second connector may not include a second connector data transmission pin. For example, the third connector (330) may not include a third connector power pin (331). In addition to the described form, the presence or absence and arrangement of pins of the first connector, the second connector, and the third connector (330) may be modified to the extent understood by a person skilled in the art.

[0046] FIG. 4 is a diagram showing the connection relationship of the pins of the connectors of a cable assembly (300) according to various embodiments. FIG. 5 is a table showing the connection relationship between the pins of the first connectors (310) of the cable assembly (300) according to various embodiments and the pins of the second connector (320), and FIG. 6 is a table showing the connection relationship between the pins of the first connectors (310) of the cable assembly (300) according to various embodiments and the pins of the third connector (330).

[0047] As described above, the presence or absence and arrangement of the pins of the first connector (310), the second connector (320), and the third connector (330) may vary, but FIG. 4 illustrates the case where the first connector (310) and the second connector (320) are Type C connectors and the third connector (330) is Type A connector.

[0048] A cable assembly (300) according to various embodiments may include a first connector (310), a second connector (320), and a third connector (330). The first connector (310) may include a first connector power pin (311), a first connector data transmission pin (312), a first connector CC pin (314), and a first connector ground pin (313). The second connector (320) may include a second connector power pin (321), a second connector CC pin (324), and a second connector ground pin (323).

[0049] The first connector power pin (311) can be connected to the second connector power pin (321). For example, the VBUS pins of the first connector power pin (311), such as B9, B4, A9, and A4, can be connected to the VBUS pins of the second connector power pin (321), such as A4, A9, B4, and B9. These can be connected individually one-to-one by wire. Alternatively, the wires connected to the first connector power pin (311) can be combined into one and integratedly connected as a single wire.

[0050] The first connector data transmission pin (312) can be connected to the third connector power pin (331). For example, the first connector data transmission pins (312), such as pins A7, A6, A3, A2, B10, and B11, can be connected to the third connector data transmission pins (332), such as pins 2, 3, 5, 6, 8, and 9. For example, the first connector data transmission pins (312) and the third connector data transmission pins (332) can be configured in the same number and can be connected individually in a one-to-one manner.

[0051] The first connector ground pin (313), the second connector ground pin (323), and the third connector ground pin (333) can all be connected. For example, the first connector ground pins (313), such as B12, B1, A12, and A1, the second connector ground pins (323), such as A1, A12, B1, and B12, and the third connector ground pins (333), such as pins 4 and 7, can all be connected.

[0052] The first connector (310) CC pin and the second connector CC pin (324) can be connected to each other.

[0053] Although not shown in FIG. 4, as described above, the second connector (320) may include a second connector data transmission pin (e.g., the second connector data transmission pin (322) of FIG. 5), and the third connector (330) may include a third connector power pin (e.g., the third connector power pin (331) of FIG. 6). For example, the second connector data transmission pin may be open so as not to be connected to the pins of the first connector (310), and the third connector power pin may be open so as not to be connected to the pins of the first connector (310).

[0054] Unlike the above, the third connector power pin may be connected to the first connector power pin (311). For example, the first connector power pin (311), the second connector power pin (321), and the third connector power pin may all be connected. In this case, the third connector (330) may be connected to an additional electronic device (1011) equipped with a reverse voltage protection design.

[0055] The connection relationships of the pins of the first connector (310), the second connector (320), and the third connector (330) illustrated in FIG. 4 are shown in the table in FIG. 5 and FIG. 6. FIG. 5 shows the connection relationships between the pins of the first connector (310) and the second connector (320). As described above, the data transmission pin (312) of the first connector and the transmission pin of the second connector (320) may not be connected, and this is indicated as NC (Not Connected) in the table. FIG. 6 shows the connection relationships between the pins of the first connector (310) and the third connector (330). As described above, the power pin (311) of the first connector and the power pin (331) of the third connector may not be connected, and this is indicated as NC in the table.

[0056] FIG. 7 is a diagram showing the connection relationship of the pins of the connectors of a cable assembly (400) (e.g., the cable assembly (300) of FIG. 1) according to various embodiments. As described above, the presence or absence and arrangement of the pins of the first connector (410) (e.g., the first connector (310) of FIG. 1), the second connector (420) (e.g., the second connector (320) of FIG. 1), and the third connector (430) (e.g., the third connector (330) of FIG. 1) may vary, but FIG. 7 illustrates the case where the first connector (410), the second connector (420), and the third connector (430) are Type C connectors.

[0057] A cable assembly (400) according to various embodiments may include a first connector (410), a second connector (420), and a third connector (430), and the first connector (410) may include a first connector power pin (411) (e.g., the first connector power pin (311) of FIG. 4), a first connector data transmission pin (412) (e.g., the first connector data transmission pin (312) of FIG. 4), a first connector CC pin (414) (e.g., the first connector CC pin (314) of FIG. 4), and a first connector ground pin (413) (e.g., the first connector ground pin (313) of FIG. 4), and the second connector (420) may include a second connector power pin (421) (e.g., the second connector power pin (321) of FIG. 4), a second connector CC pin (424) (e.g., the second connector CC pin (324) of FIG. 4), and a second It may include a connector ground pin (423) (e.g., the second connector ground pin (323) of FIG. 4), and the third connector (430) may include a third connector data transmission pin (432) (e.g., the third connector data transmission pin (332) of FIG. 4) and a third connector ground pin (433) (e.g., the third connector ground pin (333) of FIG. 4).

[0058] The first connector power pin (411) can be connected to the second connector power pin (421). For example, the VBUS pins B9, B4, A9, and A4 of the first connector power pin (411) can be connected to the VBUS pins A4, A9, B4, and B9 of the second connector power pin (421). These can be connected individually one-to-one by wire. Alternatively, the wires connected to the first connector power pin (411) can be combined into one and integratedly connected as a single wire.

[0059] The first connector data transmission pin (412) can be connected to the third connector data transmission pin (432). For example, the first connector data transmission pins (412), such as A6, A7, B11, B10, A2, A3, A11, A10, B2, and B3, can be connected to the third connector data transmission pins (432), such as A6, A7, A2, A3, B11, B10, B2, B3, A11, and A10. For example, the first connector data transmission pins (412) and the third connector data transmission pins (432) can be configured in the same number and can be connected individually in a one-to-one manner.

[0060] The first connector ground pin (413), the second connector ground pin (423), and the third connector ground pin (433) can all be connected. For example, the first connector ground pins (413), such as B12, B12, and A1, the second connector ground pins (423), such as A1, A12, B1, and B12, and the third connector ground pins (433), such as A1, A12, B1, and B12, can all be connected.

[0061] The first connector CC pin (414) and the second connector CC pin (424) can be connected to each other.

[0062] Additionally, as described above, the second connector (420) may include a second connector data transmission pin (e.g., the second connector data transmission pin (322) of FIG. 5), and the third connector (430) may include a third connector power pin (e.g., the third connector power pin (431) of FIG. 8) and a third connector CC pin (e.g., the third connector CC pin (434) of FIG. 8). For example, the second connector data transmission pin may be open so as not to be connected to the pins of the first connector (410), the third connector power pin may be open so as not to be connected to the pins of the first connector (410), and the third connector CC pin may be open so as not to be connected to the pins of the first connector (410).

[0063] Unlike the above, the third connector power pin can be connected to the first connector power pin (411). For example, the first connector power pin (411), the second connector power pin (421), and the third connector power pin can all be connected. In this case, the third connector (430) can be connected to an electronic device equipped with a reverse voltage protection design.

[0064] The connection relationship of the pins of the first connector (410) and the third connector (430) shown in FIG. 7 is shown in a table in FIG. 8. The connection relationship of the pins of the first connector (410) and the second connector (420) is the same as that shown in FIG. 5. The description of the table shown in FIG. 8 is the same as the description of the table in FIG. 6.

[0065] FIG. 9 illustrates the usage logic of a cable assembly (300) according to various embodiments. After the cable assembly (300) according to various embodiments is prepared (S510), the first connector (310) can be connected to an electronic device (101) (S520). The third connector (330) can be connected to an additional electronic device (1011) (S560). The second connector (320) can be connected to a power supply device (200) (S530). Meanwhile, the order in which the first connector (310), the second connector (320), and the third connector (330) are connected to the aforementioned counterpart (e.g., electronic device (e.g., electronic device (101) of FIG. 1)) may be reversed.

[0066] After the first communication is established between the electronic device (101) and the power supply device (200) (S540), high-speed charging can be performed through the first connector (310) and the second connector (320) (S550). For example, the first communication may be CC communication.

[0067] Separately, a second communication between the electronic device (101) and an additional electronic device (1011) can be made through data communication between the third connector (330) and the first connector (310) (S570). For example, the second communication may be data communication.

[0068] Meanwhile, even if the third connector (330) is not connected to the additional electronic device (1011), if the second connector (320) is connected to the power supply unit (200), power can be supplied to the electronic device (101) from the second connector (320) through the first connector (310). However, if the second connector (320) is not connected to the power supply unit (200), data communication between the electronic device (101) and the additional electronic device (1011) may not be possible even if the third connector (330) is connected to the additional electronic device (1011). This is because the third connector power pin (e.g., the third connector power pin (331) in FIG. 4) may be open, so the additional electronic device (1011) may not be able to recognize the electronic device (101).

[0069] FIG. 10 shows a connection situation of a cable assembly (300) according to various embodiments, FIG. 11 shows a connection situation of a cable assembly (300) according to various embodiments, and FIG. 12 shows a connection situation of a cable assembly (300) according to various embodiments.

[0070] Referring to FIG. 10, this connection situation is such that a power supply device (200) is connected to the first connector (310), an electronic device (101) is connected to the second connector (320), and a third connector (330) is connected to an additional electronic device (1011).
