The FPCB (530) can include a protection circuit (540) and a bending portion (545). For example, power stored in the battery (550) can be provided to elements (e.g., PMIC) included in the PCB (510) through the protection circuit (540) and the bending portion (545) (or a power transmission line included in the bending portion (545)).

[0104] According to one embodiment, the protection circuit (540) may perform a function of protecting the FPCB (530) during the step of assembling the battery (550) or the step of repairing the battery (550). For example, the protection circuit (540) may prevent carbonization of the FPCB (530) (e.g., the second connector (C2) portion) when the connector of the FPCB (530) (e.g., the second connector (C2)) is not completely connected or fixed to the PCB (510). For example, the protection circuit (540) may be disposed in the first housing (501) or the second housing (502). However, the position at which the protection circuit (540) is disposed may be variously changed, and the features of the present invention may not be limited thereto.

[0105] According to one embodiment, the bending portion (545) can provide or transmit power stored in the battery (550) to elements (e.g., a PMIC) included in the PCB (510). For example, the bending portion (545) can include at least one line (e.g., a power transmission line) through which power can be transmitted or provided. For example, the bending portion (545) can be implemented with a flexible material. For example, the bending portion (545) can be implemented with a material that can be bent.

[0106] In one embodiment, when the electronic device (101) includes a rollable display (or slideable display), the FPCB (530) may be implemented to be longer than a specified length associated with sliding (or sliding movement) of the rollable display (e.g., a length by which the rollable display is extended). For example, the length of the bending portion (545) may be longer than the length by which the rollable display is extended.

[0107] According to one embodiment, when the electronic device (101) includes a foldable display or a rollable display, the FPCB (530) (or the bending portion (545)) may be folded at least once. For example, when the FPCB (530) (or the bending portion (545)) is folded multiple times, the folded axes of the FPCB (530) (or the bending portion (545)) may be orthogonal to each other. At least some of the folded axes of the FPCB (530) (or the bending portion (545)) may be in the same direction or different directions.

[0108] Previously, electronic devices could connect multiple divided mounting areas (e.g., a first housing (501) and a second housing (502)) via FPCBs. However, the FPCB structure may have greater fluidity than a PCB structure without a folding axis. For example, during the manufacturing stage (or assembly process) of an electronic device or a battery repair stage, if the line of the FPCB that provides power from the battery is not completely connected or fixed to the corresponding connector, the power provided from the battery may be short-circuited to the surrounding ground. In this case, carbonization due to overcurrent may occur in the relevant part, which may damage the electronic device.

[0109] According to one embodiment, the protection circuit (540) may be configured to supply, provide or apply battery power or battery voltage to the PCB (510) (or power management circuit (PMIC)) through the second connector (C2) only after the first connector (C1) of the FPCB (530) is fully connected or engaged with the battery (550) and the second connector (C2) of the FPCB (530) is fully connected or engaged with the PCB (510). In addition, the protection circuit (540) may perform the above-described operation without providing a separate power source, unlike the conventional method.

[0110] Through this, according to one embodiment, the FPCB (530) can supply, provide or apply the battery voltage to the PCB (510) (or elements included in the PCB (510)) only when the connectors of the FPCB (530) (e.g., the first connector (C1) and / or the second connector (C2)) are completely (or normally) connected or engaged with the battery and the PCB (510) without separate software control. In addition, according to one embodiment, the FPCB (530) can block the supply, provide or apply the battery voltage to the PCB (510) (or elements included in the PCB (510)) when the corresponding connectors of the FPCB (530) (e.g., the first connector (C1) and / or the second connector (C2)) are not completely connected or engaged with the PCB (510) and / or the battery (550) without separate software control. Accordingly, according to one embodiment, the FPCB (530) can solve a problem (e.g., carbonization) that may occur when power provided from the battery (550) is short-circuited to ground.

[0111] FIG. 6 is a block diagram of a protection circuit of an FPCB connecting a battery disposed in a first housing and a printed circuit board (PCB) disposed in a second housing according to one embodiment of the present disclosure.

[0112] Referring to FIG. 6, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a printed circuit board (PCB) (510), a battery (550), and an FPCB (530) connecting the PCB (510) and the battery (550).

[0113] According to one embodiment, a PCB (510) may be placed in a second housing (e.g., the second housing (502) of FIG. 5). The PCB (510) may include a power management circuit (PMIC) (515) and a plurality of loads (a first load (517), a second load (518), and an Nth load (519), where N is a natural number of 3 or greater). For example, the power management circuit (515) may receive power from a battery (550). The power management circuit (515) may supply or provide the received power to the plurality of loads (517, 518, and 519). For example, the plurality of loads (517, 518, and 519) may be elements that require power included in the electronic device (101).

[0114] According to one embodiment, the PCB (510) may include a receptor that can receive or be connected to a second connector (C2). The receptor may include a plurality of pin connection portions that can receive or be connected to a plurality of pins included in the second connector (515), respectively. Based on the plurality of pins included in the FPCB (or the second connector (C2)) being connected to the plurality of pins of the receptor, power provided from the battery (550) may be supplied or provided to the power management circuit (515) through the second connector (C2). For example, a first pin connection portion that receives (or is connected to) a first pin (521) and a second pin connection portion that receives (or is connected to) a second pin (522) may form a part of an electrical loop when connected to the first pin (521) and the second pin (522), respectively. For example, the first pin connection portion and the second pin connection portion of the receptor may be directly connected within the receptor. Alternatively, the first pin connection portion and the second pin connection portion of the receptor may be connected via a path on the PCB (510). For example, the first pin connection portion and the second pin connection portion may form part of an electrical loop within the PCB (510) (or within the receptor).

[0115] According to one embodiment, the FPCB (530) may include a second connector (C2), a protection circuit (540), and a banding portion (e.g., the banding portion (545) of FIG. 5). Depending on the implementation, the protection circuit (540) may not include the first connector (C1). In this case, the FPCB (530) may further include the first connector (C1).

[0116] For convenience of explanation, below, it will be explained that the protection circuit (540) allows or blocks power to be supplied from the battery (550) to the PCB (510) on the assumption that the battery (550) is connected to the first connector (C1).

[0117] According to one embodiment, the second connector (C2) may include a first pin (521), a second pin (522), and a third pin (523). For example, the first pin (521) and the second pin (522) may be pins for applying a voltage to turn on the switch (Q1). For example, the first pin (521) and the second pin (522) may be electrically loop-connectable to each other. For example, when the first pin (521) and the second pin (522) are connected to a PCB (e.g., a receptor of the PCB), the first pin (521) and the second pin (522) may form an electrical loop (or an electrical loop circuit). For example, the electrical loop may be formed at a portion corresponding to the first pin (521) and the second pin (522) of the second connector (C2). At this time, the switch (Q1) included in the protection circuit (540) may form part of an electrical loop with the first pin (521) and the second pin (522). The third pin (523) may be a pin for receiving power from the battery (550) and supplying the received power to elements (e.g., power management circuit (515)) arranged on the PCB (510). For example, the third pin (523) may be arranged outside the electrical loop. For example, the third pin (523) may be connected to the power management circuit (515). Power provided through the battery (550) may be provided to the power management circuit (515) through the third pin (523).

[0118] In one embodiment, the protection circuit (540) may allow power from the battery (550) to be supplied to the PCB (510) (or power management circuit (515)) through the third pin (523) when each of the first pin (521), the second pin (522), and the third pin (523) is connected to the PCB (510).

[0119] In one embodiment, the protection circuit (540) may block power from the battery (550) from being supplied to the PCB (510) (or power management circuit (515)) through the third pin (523) when at least one of the first pin (521), the second pin (522), and the third pin (523) is not connected to the PCB (510).

[0120] In one embodiment, when only the first pin (521) is connected to the PCB (e.g., a receptor of the PCB), the voltage provided from the battery (550) may not be applied to the second pin (522). Alternatively, when only the second pin (522) is connected to the PCB (e.g., a receptor of the PCB), the voltage provided from the battery (550) may not be applied to the first pin (522) and the second pin (522). In this case, a voltage converging to 0 V may be applied as a gate voltage to the switch (Q1).

[0121] In one embodiment, when both the first pin (521) and the second pin (522) are connected to a PCB (e.g., a receptor of the PCB), power (or voltage) provided from the battery (550) may be provided to the third pin (523). At this time, a voltage corresponding to a value of the battery voltage (VBAT) distributed by the first resistor (R1) and the second resistor (R2) may be applied to the switch (Q1) (or the gate of the switch (Q1)).

[0122] According to one embodiment, the banding portion may connect between the protection circuit (540) and the second connector (C2). For example, the banding portion may include a plurality of lines that are respectively connected to pins (522, 523, and 524) of the second connector (C2). For example, a first line may be connected to a first pin (521), a second line may be connected to a second pin (522), and a third line may be connected to a third pin (523).

[0123] According to one embodiment, the protection circuit (540) may include a first resistor (R1), a second resistor (R2), a switch (Q1), and a first connector (C1). Depending on the implementation, the first connector (C1) may not be included in the protection circuit (540). Alternatively, at least one of the first resistor (R1) or the second resistor (R2) may not be included in the protection circuit (540).

[0124] According to one embodiment, the first connector (C1) may be connected to the battery (550). For example, the first connector (C1) may include at least one pin for connection with the battery (550). When the battery (550) is connected to the first connector (C1) (or a corresponding pin of the first connector (C1)), power (or battery voltage (VBAT)) provided from the battery (550) may be transferred (e.g., supplied, provided, or applied) to the switch (Q1).

[0125] According to one embodiment, the first resistor (R1) may be connected in series to a first line of the bending portion, which is configured to be connected to a first pin (521) of the second connector (C2). For example, one end of the first resistor (R1) may be connected to the first pin (521) through the first line, and the other end of the first resistor (R1) may be connected to the first connector (C1). The second resistor may be connected in parallel to a second line of the bending portion, which is configured to be connected to a second pin (522) of the second connector (C2). For example, one end of the second resistor (R2) may be connected to ground, and the other end of the second resistor (R2) may be connected to the second pin (522) and the switch (Q1) (or the gate of the switch (Q1)) through the second line.

[0126] According to one embodiment, the switch (Q1) can be turned on or off based on a gate voltage obtained by dividing a voltage provided (or applied) from the battery (550) by the first resistor (R1) and the second resistor (R2). For example, the gate voltage can be a voltage obtained by dividing (e.g., voltage dividing) a battery voltage (VBAT) by the first resistor (R1) and / or the second resistor (R2). The gate voltage can be applied to the switch (Q1) as a gate signal of the switch (Q1). For example, when the gate voltage is greater than or equal to a threshold voltage (or threshold voltage) of the switch (Q1), the switch (Q1) can be turned on. Alternatively, when the gate voltage is less than the threshold voltage of the switch (Q1), the switch (Q1) can be turned off. For example, the switch (Q1) can include an N-type metal oxide semiconductor field effect transistor (MOSFET).

[0127] According to one embodiment, when the first pin (521) of the second connector (C2) is connected to the PCB (510) and the second pin (522) of the second connector (C2) is connected to the PCB (510), a second voltage higher than the threshold voltage of the switch (Q1) may be applied to the switch (Q1). For example, when the first pin (521) of the second connector (C2) is connected to the PCB (510) and the second pin (522) of the second connector (C2) is connected to the PCB (510), the second voltage may be expressed as in Mathematical Expression 1 below. For example, R2 may represent the resistance value of the second resistor (R2), R1 may represent the resistance value of the first resistor (R1), VG may represent the second voltage, and VBAT may represent the battery voltage.

[0128]

[0129] Meanwhile, when the first pin (521) of the second connector (C2) is connected to the PCB (510) and the second pin (522) of the second connector (C2) is connected to the PCB (510), the voltage applied to the first pin (521) can be expressed as in mathematical expression 2. For example, R2 may represent the resistance value of the second resistor (R2), R1 may represent the resistance value of the first resistor (R1), V1 may represent the voltage applied to the first pin (521), and VBAT may represent the battery voltage.

[0130]

[0131] Considering the above mathematical expressions 1 and 2, the first resistor (R1) and the second resistor (R2) can be set so that the second voltage (VG) is greater than the threshold voltage of the switch (Q1). In addition, when the first pin (521) (or the second pin (522)) is not connected or engaged with the PCB (510) (or the receptor of the PCB (510)) (e.g., when the pin is short-circuited to ground), the first resistor (R1) and the second resistor (R2) can be set so that the R1 / R2 value has a sufficiently large value to minimize overcurrent or leakage current to the pin.

[0132] In one embodiment, when the first pin (521) of the second connector (C2) is not connected to the PCB (510) (or the receptor of the PCB (510)) or the second pin (522) of the second connector (C2) is not connected to the PCB (510) (or the receptor of the PCB (510)), a first voltage lower than the threshold voltage (or threshold voltage) of the switch (Q1) may be applied to the switch (Q1). Alternatively, when the first pin (521) of the second connector (C2) is not connected to the PCB (510) (or the receptor of the PCB (510)) and the second pin (522) of the second connector (C2) is not connected to the PCB (510) (or the receptor of the PCB (510)), a first voltage lower than the threshold voltage (or threshold voltage) of the switch (Q1) may be applied to the switch (Q1). For example, the first voltage may be 0 V or a voltage that converges to 0 V.

[0133] According to one embodiment, when the switch (Q1) is turned on, power provided from the battery (550) may be supplied or provided to the second connector (C2) (or the third pin (523)). At this time, the battery voltage (VBAT) applied to the switch (Q1) may be supplied or applied to the second connector (C2) (or the third pin (523)).

[0134] According to one embodiment, when the switch (Q1) is turned off, power provided from the battery (550) may be blocked from being supplied or provided to the second connector (C2) (or the third pin (523)). That is, when the switch (Q1) is turned off, power provided from the battery (550) may not be supplied or applied to the second connector (C2) (or the third pin (523)). At this time, the battery voltage (VBAT) applied to the switch (Q1) may not be provided to the second connector (C2) (or the third pin (523)).

[0135] Based on the above-described method, the electronic device (101) can prevent or minimize the occurrence of carbonization of the pins of the second connector (C2) even when the connection or engagement between the PCB (510) and the second connector (C2) is incorrect, without separate control or separate power, by using the protection circuit (540).

[0136] Meanwhile, at least some of the operations of the electronic device of FIG. 7 described below may be performed by the protection circuit (540). The operations of the protection circuit (540) may be performed without separate control by a processor or control circuit. Furthermore, the operations of the protection circuit (540) may be performed without a separate power supply. That is, the operations of the protection circuit (540) described below may be performed based on circuit characteristics.

[0137] FIG. 7 is a flowchart illustrating a schematic operation of a protection circuit included in an electronic device according to an embodiment of the present disclosure.

[0138] Referring to FIG. 7, according to one embodiment, in operation 701, a battery (e.g., battery (550) of FIG. 5) and a first connector (e.g., first connector (C1) of FIG. 5) may be connected. For example, during an assembly step or a repair step of an electronic device (101), the battery (550) may be connected to the first connector (C1).

[0139] According to one embodiment, in operation 703, an operation may be performed in which all of the first pin (521), the second pin (522), and the third pin (523) of the second connector (e.g., the second connector (C2) of FIG. 5) are connected to a PCB (e.g., the PCB (510) of FIG. 5). For example, at least one of the first pin (521), the second pin (522), and the third pin (523) of the second connector (C2) may be incorrectly connected to the PCB (510). Alternatively, each of the first pin (521), the second pin (522), and the third pin (523) of the second connector (C2) may be normally connected to the PCB (510).

[0140] In one embodiment, when all of the first pin (521), the second pin (522), and the third pin (523) of the second connector (C2) are not connected to the PCB (510) (NO of operation 703), the power may be blocked from being supplied from the first battery (e.g., the battery (550) of FIG. 5) to the power management circuit (e.g., the power management circuit (515) of FIG. 5) based on the switch (Q1) being turned off by a first voltage (e.g., a voltage converging to 0 V) ​​applied to the switch (Q1). For example, the protection circuit (540) may block the supply or provision of the first battery voltage (e.g., the battery voltage VBAT of FIG. 5) from the first battery (e.g., the battery (550) of FIG. 5) to the second connector (C2) (e.g., the third pin (523)). For example, the first voltage may be a voltage applied to the gate of the switch (Q1) when the first pin (521) and / or the second pin (522) of the second connector (C2) is not connected to the PCB (510). For example, the first voltage may be lower than the threshold voltage (or threshold voltage) of the switch (Q1).

[0141] In one embodiment, when the first pin (521), the second pin (522), and the third pin (523) of the second connector (C2) are all connected to the PCB (510) (example of operation 703), power may be allowed to be supplied from the first battery (e.g., the battery (550) of FIG. 5) to the power management circuit (e.g., the power management circuit (515) of FIG. 5) based on the switch being turned on by a second voltage applied from the first battery (550) to the switch (Q1). For example, the protection circuit (540) may supply or provide the first battery voltage from the first battery (550) to the second connector (C2). For example, the second voltage may be a voltage applied to the gate of the switch (Q1) when each of the first pin (521) and the second pin (522) of the second connector (C2) is connected to the PCB (510). For example, the second voltage may be higher than or equal to the threshold voltage (or threshold voltage) of the switch (Q1).

[0142] In one embodiment, when the first pin (521) and the second pin (522) of the second connector (C2) are connected to the PCB (510) and the third pin (523) is not connected to the PCB (510), the switch (Q1) may be turned on, but power (or the first battery voltage (VBAT)) may not be supplied or provided to the third pin (523).

[0143] Based on the above-described method, the electronic device (101) can prevent or minimize the occurrence of carbonization of the pins of the second connector (C2) even when the connection or engagement between the PCB (510) and the second connector (C2) is incorrect, without separate control or separate power, by using the protection circuit (540).

[0144] FIGS. 8A, 8B, 8C, and 8D are drawings for explaining operations of a protection circuit for connection states between a second connector disposed in a second housing and a PCB according to one embodiment of the present disclosure.

[0145] Referring to FIGS. 8A to 8D , according to one embodiment, a battery (e.g., battery (550) of FIG. 5 ) may be connected to a first connector (C1), and a third pin (523) of a second connector (C2) may be connected or bonded to a PCB (e.g., PCB (510) of FIG. 5 ). The following FIGS. 8A to 8D will explain that a switch (Q1) is turned on / off depending on whether the first pin (521) and the second pin (522) of the second connector (C2) and the PCB (510) are connected or bonded.

[0146] Referring to FIG. 8A, according to one embodiment, the first pin (521) and the second pin (522) of the second connector (C2) may not be connected or bonded to the PCB (510). The first pin (521) and the second pin (522) may be short-circuited to ground. As a result, a gate voltage converging to 0 V may be applied to the switch (Q1). As a voltage lower than the threshold voltage of the switch (Q1) is applied to the gate of the switch (Q1), the switch (Q1) may be turned off. The battery voltage (VBAT) may or may not be provided to the third pin (523) as the switch (Q1) is turned off. For example, even if the first pin (521) and the second pin (522) are not connected or incorrectly connected to the PCB (510), the battery voltage (VBAT) may not be applied to the third pin (523). Due to this, even if the first pin (521) and the second pin (522) are not connected or incorrectly connected to the PCB (510), the third pin (523) may not be carbonized.

[0147] Referring to FIG. 8B, according to one embodiment, the first pin (521) and the third pin (523) of the second connector (C2) may be connected (or bonded) to the PCB (510), and the second pin (522) of the second connector (C2) may not be connected (or bonded) to the PCB (510). The second pin (522) may be short-circuited to ground. As a result, a gate voltage converging to 0 V may be applied to the switch (Q1). As a voltage lower than the threshold voltage of the switch (Q1) is applied to the gate of the switch (Q1), the switch (Q1) may be turned off. The battery voltage (VBAT) may or may not be provided to the third pin (523) as the switch (Q1) is turned off. For example, even if the second pin (522) is not connected or incorrectly connected to the PCB (510), the battery voltage (VBAT) may not be applied to the third pin (523). As a result, even if the second pin (522) is not connected or incorrectly connected to the PCB (510), the third pin (523) may not be carbonized.

[0148] Referring to FIG. 8C, according to one embodiment, the first pin (521) of the second connector (C2) may not be connected (or bonded) to the PCB (510), and the second pin (522) and the third pin (523) of the second connector (C2) may be connected (or bonded) to the PCB (510). The first pin (521) may be shorted to ground. As a result, a gate voltage converging to 0 V may be applied to the switch (Q1). As a voltage lower than the threshold voltage of the switch (Q1) is applied to the gate of the switch (Q1), the switch (Q1) may be turned off. The battery voltage (VBAT) may or may not be provided to the third pin (523) as the switch (Q1) is turned off. For example, even if the first pin (521) is not connected or incorrectly connected to the PCB (510), the battery voltage (VBAT) may not be applied to the third pin (523). As a result, even if the first pin (521) is not connected or incorrectly connected to the PCB (510), the third pin (523) may not be carbonized.

[0149] Referring to FIG. 8D, according to one embodiment, the first pin (521), the second pin (522), and the third pin (523) of the second connector (C2) may be connected or bonded to the PCB (510). The first pin (521) and the second pin (522) may form an electrical loop. The first pin (521) and the second pin (522) may be connected to a first line and a second line of a bending portion of the FPCB. The switch (Q1) may form a part of the electrical loop. As a result, a second voltage, which is a battery voltage (VBAT) divided by the first resistor (R1) and the second resistor (R2), may be applied to the gate of the switch (Q1). For example, the second voltage may be higher than a threshold voltage (or threshold voltage) of the switch (Q1). When a voltage higher than the threshold voltage (or threshold voltage) of the switch (Q1) is applied to the gate of the switch (Q1), the switch (Q1) can be turned on. Power (or battery voltage (VBAT)) from the battery can be supplied, provided, or applied to the third pin (523) when the switch (Q1) is turned on. For example, when the first pin (521) and the second pin (522) are normally (or completely) connected or engaged with the PCB (510), the battery voltage (VBAT) can be provided or applied to the third pin (523). Therefore, the battery voltage (VBAT) can be applied to the third pin (523) only when the first pin (521) and the second pin (522) are normally connected or engaged with the PCB (510).

[0150] Based on the above-described method, the electronic device (101) can prevent or minimize the occurrence of carbonization of the pins of the second connector (C2) even when the connection or engagement between the PCB (510) and the second connector (C2) is incorrect, without separate control or separate power, by using the protection circuit (540).

[0151] In the following Figures 9 through 15, embodiments in which a protection circuit is applied in various form factors will be described. However, these are exemplary, and the features of the present invention may not be limited thereto.

[0152] FIG. 9 is a block diagram of an FPCB connecting a plurality of batteries arranged in a first housing and a printed circuit board (PCB) arranged in a second housing according to one embodiment of the present disclosure.

[0153] Referring to FIG. 9, according to one embodiment, a battery (550) of an electronic device (e.g., the electronic device (101) of FIG. 5) may include a plurality of batteries (e.g., a first battery (551) and a second battery (552)). Alternatively, the battery (550) of FIG. 5 may be replaced with a plurality of batteries (e.g., a first battery (551) and a second battery (552)). For example, the plurality of batteries (551, 552) may be implemented as a single battery package. Alternatively, the plurality of batteries (551, 552) may be implemented as separate battery packages.

[0154] According to one embodiment, when at least one of the first pin (521) or the second pin (522) of the second connector (C2) is not connected to a PCB (e.g., PCB (510) of FIG. 5), the switch (Q1) may be turned off by a first voltage (e.g., 0 V or a voltage converging to 0 V) ​​provided by the first battery (551). For example, the first voltage may be lower than a threshold voltage of the switch (Q1). Based on the switch (Q1) being turned off, the provision of the first battery voltage (VBAT1) and the second battery voltage (VBAT2) from the first battery (551) and the second battery (552) to the second connector (C2) (or the third pin (523)) through the banding portion (545) may be blocked. For example, the first battery voltage (VBAT1) may be a voltage of power provided by the first battery (551). The second battery voltage (VBAT2) may be the voltage of the power provided by the second battery (552).

[0155] According to one embodiment, when each of the first pin (521) and the second pin (522) of the second connector (C2) is connected to the PCB (510), the switch (Q1) may be turned on by the second voltage provided by the first battery (551). For example, the second voltage may be higher than the threshold voltage of the switch (Q1). Based on the turning on of the switch (Q1), it may be allowed to supply or provide the first battery voltage (VBAT1) and the second battery voltage (VBAT2) from the first battery (551) and the second battery (552) to the second connector (C2) (or the third pin (523)) through the FPCB (520) (or the bending portion (545) of the FPCB (520)).

[0156] Based on the above-described method, the electronic device (101) can prevent or minimize the occurrence of carbonization of pins of the second connector (C2) even when the connection or engagement between the PCB (510) and the second connector (C2) is incorrect, without separate control or separate power, even if it includes multiple batteries (551, 552).

[0157] FIGS. 10A, 10B, and 10C are drawings of a first battery disposed in a first housing, a printed circuit board (PCB) disposed in a second housing, and an FPCB connecting the second battery according to one embodiment of the present disclosure.

[0158] Referring to FIG. 10A, according to one embodiment, an electronic device (e.g., electronic device (101) of FIG. 1) may include a rollable display (or slideable display).

[0159] Referring to (a) of FIG. 10A, according to one embodiment, an electronic device may include a first housing (1001) and a second housing (1002).

[0160] Referring to (b) of FIG. 10A, according to one embodiment, the FPCB (1030) may include a second connector (C2), a protection circuit (1040), and a bending portion (1045). Depending on the implementation, the protection circuit (1040) may not include the first connector (C1). In this case, the FPCB (1030) may further include the first connector (C1). For example, the protection circuit (1040) may be disposed in the first housing (1001). For example, the FPCB (1030) (e.g., the bending portion (1045)) may be folded multiple times. For example, at least some of the folded axes of the FPCB (1030) (e.g., the bending portion (1045)) may be in the same direction or different directions. Depending on the implementation, the folded axes of the PCB (1030) (e.g., the bending portion (1045)) may be orthogonal to each other.

For example, the protection circuit (1041) may be disposed in the first housing (1003). For example, the FPCB (1030) (e.g., the bending portion (1046)) may be folded multiple times. Depending on the implementation, the FPCB (1030) (e.g., the bending portion (1046)) may be folded at a position corresponding to an area where the foldable display is folded.

[0164] According to one embodiment, the protection circuit (1040 or 1041) described in FIGS. 10a and 10b may be implemented identically or similarly to the protection circuit described in FIG. 10c.

[0165] Referring to FIG. 10C, according to one embodiment, a protection circuit (1040) and a first battery (1050) (e.g., the first battery (1051) of FIG. 10A or the first battery (1053) of FIG. 10B) may be disposed in a first housing (e.g., the first housing (1001) of FIG. 10A or the first housing (1003) of FIG. 10B). A PCB (1010) and a second battery (1060) (e.g., the second battery (1052) of FIG. 10A or the second battery (1054) of FIG. 10B) may be disposed in a second housing (e.g., the second housing (1002) of FIG. 10A or the second housing (1004) of FIG. 10B).

[0166] According to one embodiment, the PCB (1010) may include a power management circuit (515), a plurality of loads (517, 518, 519), a first resistor (R1), and a third connector (C3). For example, the power management circuit (515) and the plurality of loads (517, 517, 519) may be implemented identically or similarly to the power management circuit (515) and the plurality of loads (517, 517, 519) described in FIG. 6.

[0167] In one embodiment, the third connector (C3) may be connected to the second battery (1060). For example, the third connector (C3) may include at least one pin that may be connected to the second battery (1060).

[0169] According to one embodiment, the second connector (C2) may include a first pin (1021) and a second pin (1022). For example, the first pin (1021) may be connected to the third connector (C3) via a line including a first resistor (R1).

The second pin (1022) may be a pin for receiving power provided from the first battery (550) and supplying the received power to elements (e.g., a power management circuit (515)) arranged on the PCB (1010). For example, the second pin (1022) may be connected to the power management circuit (515). Power provided through the first battery (1050) can be provided to the power management circuit (515) through the second pin (1022).

[0170] According to one embodiment, when the first pin (1021) is not connected to the PCB (1010), a first voltage may be applied to the switch (Q1) (or the gate of the switch (Q1)). For example, the first voltage may be lower than the threshold voltage of the switch (Q1). For example, the first voltage may be 0 V or a voltage that converges to 0 V. The switch (Q1) may be turned off by the first voltage. Based on the switch (Q1) being turned off, the first battery voltage (VBAT) may be blocked from being provided from the first battery (1050) to the second connector (C2) (or the second pin (1022)) through the bending portion (1045) (or the second line of the bending portion (1045)). That is, power provided from the first battery (1050) may not be provided to the first pin (1021).

[0171] According to one embodiment, when each of the first pin (1021) and the second pin (1022) is connected to the PCB (1010), a second voltage may be applied to the switch (Q1) (or the gate of the switch (Q1)). For example, the second voltage may be higher than or equal to a threshold voltage of the switch (Q1). For example, the second voltage may be a voltage provided by the second battery (1060) divided (or voltage divided) by the first resistor (R1) and the second resistor (R2). The switch (Q1) may be turned on by the second voltage. Based on the turning on of the switch (Q1), the first battery voltage (VBAT) may be provided from the first battery (1050) to the second connector (C2) (or the second pin (1022)) through the bending portion (1045) (or the second line of the bending portion (1045)). That is, power provided from the first battery (1050) can be provided to the second pin (1022). In addition, power provided from the first battery (1050) can be supplied to the power management circuit (515) through the second pin (1022).

[0175] According to one embodiment, the FPCB may include a second connector (C2), a protection circuit (1140), and a banding portion (e.g., 1045 in FIG. 10a). Depending on the implementation, the protection circuit (1140) may not include the first connector (C1). In this case, the FPCB may further include the first connector (C1). For example, the banding portion (e.g., 1045 in FIG. 10a) may include a first line connected to the first pin (1121) and a second line connected to the second pin (1122).

[0176] According to one embodiment, when the first pin (1121) is not connected to the PCB (1110), a first voltage may be applied to the switch (Q1) (or the gate of the switch (Q1)). For example, the first voltage may be lower than a threshold voltage (or threshold voltage) of the switch (Q1). For example, the first voltage may be 0 V or a voltage that converges to 0 V. The switch (Q1) may be turned off by the first voltage. Based on the switch (Q1) being turned off, the supply or provision of power (e.g., the first battery voltage (VBAT)) from the first battery (1050) to the second connector (C2) (or the second pin (1122)) through the bending portion (or the second line of the bending portion) may be blocked. That is, power provided from the first battery (1050) may not be provided to the second pin (1122).

[0177] According to one embodiment, when each of the first pin (1121) and the second pin (1122) is connected to the PCB (1110), a second voltage may be applied to the switch (Q1) (or the gate of the switch (Q1)). For example, the second voltage may be higher than or equal to a threshold voltage (or threshold voltage) of the switch (Q1). For example, the second voltage may be a voltage provided by the second battery (1060) divided (or voltage divided) by the first resistor (R1) and the second resistor (R2). The switch (Q1) may be turned on by the second voltage. Based on the switch (Q1) being turned on, power (e.g., the first battery voltage (VBAT)) may be provided from the first battery (1050) to the second connector (C2) (or the second pin (1122)) through the bending portion (or the second line of the bending portion). That is, power provided from the first battery (1050) can be provided to the second pin (1122). In addition, power provided from the first battery (1050) can be supplied to the power management circuit (515) through the second pin (1122).

[0178] FIGS. 12A and 12B are drawings of an FPCB connecting a battery disposed in a first housing and a printed circuit board (PCB) disposed in a second housing according to one embodiment of the present disclosure.

[0179] Referring to FIG. 12A, according to one embodiment, a protection circuit (1240) of an FPCB (e.g., protection circuit (540) of FIG. 6) may be placed in a second housing of the electronic device (e.g., second housing (502) of FIG. 5). For example, the protection circuit (1240) may be placed near the second connector (C2).

[0180] Referring to FIG. 12b, according to one embodiment, the PCB (510) and the protection circuit (1240) may be placed in a second housing of the electronic device (e.g., the second housing (502) of FIG. 5). For example, the PCB (510) may be implemented in a manner identical to or similar to the PCB (510) described in FIG. 6.

[0181] According to one embodiment, the first connector (C1) and the battery (550) may be disposed in a first housing of the electronic device (e.g., the first housing (501) of FIG. 5). The bending portion of the FPCB (e.g., the bending portion (545) of FIG. 5) may electrically connect the protection circuit (1240) and the second connector (C2). In addition, the bending portion of the FPCB (e.g., the bending portion (545) of FIG. 5) may electrically connect the protection circuit (1240) and the first connector (C1). For example, the battery (550) may be connected to the first connector (C1). In addition, the battery (550) may provide power (or battery voltage (VBAT)) to the switch (Q1) through the first connector (C1) and the bending portion of the FPCB.

[0182] According to one embodiment, when at least one of the first pin (521) or the second pin (522) is not connected to the PCB (510), the switch (Q1) may be turned off by a first voltage applied to the switch (Q1). For example, the first voltage (e.g., 0 V or converging to 0 V) ​​may be lower than a threshold voltage (or threshold voltage) of the switch (Q1). Based on the switch (Q1) being turned off, the battery voltage (VBAT) may be blocked from being provided from the battery (550) to the second connector (C2) (or the third pin (523)). That is, as the switch (Q1) is turned off, the battery voltage (VBAT) may not be applied to the third pin (523). That is, as the switch (Q1) is turned off, 0 V (or a voltage converging to 0 V) ​​may be applied to the third pin (523). Through this, when at least one of the first pin (521) or the second pin (522) is not connected to the PCB (510), the third pin (523) may not be carbonized.

[0183] According to one embodiment, when each of the first pin (521), the second pin (522), and the third pin (523) is connected to the PCB (510), the switch (Q1) may be turned on by a second voltage applied from the battery (550) to the switch (Q1). Based on the turning on of the switch (Q1), the battery voltage (VBAT) may be provided from the battery (550) to the second connector (C2) (or the third pin (523)). That is, as the switch (Q1) is turned on, the power provided from the battery (550) may be provided to the power management circuit (515). Through this, when all of the first pin (521), the second pin (522), and the third pin (523) are connected to the PCB (510), the power (or the battery voltage (VBAT)) provided from the battery (550) may be applied to the third pin (523).

[0184] FIG. 13 is a diagram of a protection circuit included in a battery disposed in a first housing according to one embodiment of the present disclosure.

[0185] Referring to FIG. 13, according to one embodiment, a protection circuit (1340) of an FPCB (e.g., the protection circuit (540) of FIG. 6) may be included in a protection circuit module (PCM) of a battery (550). For example, the battery (550) may be placed in a first housing (e.g., the first housing (501) of FIG. 5) of an electronic device (e.g., the electronic device (101) of FIG. 1). The PCB (510) may be placed in a second housing (e.g., the second housing (502) of FIG. 5) of the electronic device. The PCB (510) may be implemented in the same or similar manner as the PCB (510) of FIG. 6.

[0186] According to one embodiment, the first connector (C1) may be arranged in the first housing (e.g., the first housing (501) of FIG. 5). For example, the FPCB (or the bending portion of the FPCB (e.g., the bending portion (545) of FIG. 5)) may connect between the second connector (C2) and the first connector (C1). For example, the first connector (C1) may include a plurality of pins for connecting the protection circuit (1340) and the second connector (C2). The plurality of pins may be connected to a plurality of pins (521, 522, 523) of the second connector (C2), respectively. Depending on the implementation, the first connector (C1) may be omitted.

[0187] According to one embodiment, the protection circuit (1340) may be implemented identically or similarly to the protection circuit (540) described in FIG. 6. Accordingly, the method by which the protection circuit (1340) operates will be omitted as it overlaps with the description of FIG. 6.

[0188] FIG. 14 is a drawing of a protection circuit included in an FPCB connecting a battery disposed in a first housing and a printed circuit board (PCB) disposed in a second housing according to one embodiment of the present disclosure.

[0189] Referring to Fig. 14, the manner in which the switch (Q2) is turned on may be different from that of Fig. 6. For example, the switch (Q2) may be implemented in a low active manner (e.g., turned on at a voltage lower than the threshold voltage and turned off at a voltage higher than the threshold voltage). For example, the switch (Q2) may be implemented as a P-type MOSFET.

[0190] According to one embodiment, the PCB (1410) may include a power management circuit (515) and a plurality of loads (517, 518, 519). For example, the power management circuit (515) and the plurality of loads (517, 517, 519) may be implemented identically or similarly to the power management circuit (515) and the plurality of loads (517, 517, 519) described in FIG. 6.

[0191] According to one embodiment, the FPCB (1420) may include a second connector (C2), a protection circuit (1440), and a banding portion. Depending on the implementation, the protection circuit (1440) may not include the first connector (C1). In this case, the FPCB (1420) may include the first connector (C1).

[0192] According to one embodiment, the second connector (C2) may include a first pin (1421) and a second pin (1423). For example, the first pin (1421) may be a pin for applying a voltage to turn on (or off) the switch (Q2). One end of the first pin (1421) may be connected to the ground (1435). The other end of the first pin (1421) may be connected to the switch (Q2) (e.g., the gate of the switch (Q2)) through a bending portion of the FPCB. The second pin (1423) may be a pin for receiving power provided from the first battery (550) and supplying the received power to elements (e.g., the power management circuit (515)) arranged on the PCB (1410). The second pin (1423) can be connected to a protection circuit (1440) (or switch (Q2)) through the banding portion of the FPCB. For example, the second pin (1423) can be connected to a power management circuit (515). Power provided through the first battery (550) can be provided to the power management circuit (515) through the second pin (1423).

[0193] In one embodiment, the protection circuit (1440) may allow power from the first battery (550) to be supplied to the PCB (1410) (or power management circuit (515)) through the second pin (1423) when each of the first pin (1421) and the second pin (1423) is connected to the PCB (1410).

[0194] In one embodiment, the protection circuit (1440) may block power from the first battery (550) from being supplied to the PCB (1410) (or the power management circuit (515)) through the second pin (1423) when at least one of the first pin (1421) and the second pin (1423) is not connected to the PCB (1410).

[0195] According to one embodiment, the protection circuit (1440) and the battery (550) may be placed in a first housing of the electronic device (e.g., the first housing (501) of FIG. 5). The banding portion of the FPCB may electrically connect the protection circuit (1440) and the first connector (C2). For example, the battery (550) may be connected to the first connector (C1). In addition, the battery (550) may provide power (or battery voltage (VBAT)) to the switch (Q2) through the first connector (C1).

[0196] According to one embodiment, when the first pin (1421) is not connected to the PCB (1410), the switch (Q2) may be turned off by a third voltage applied to the switch (Q2). For example, the third voltage may be a voltage that is higher than or equal to a threshold voltage (or threshold voltage) of the switch (Q2). Based on the switch (Q2) being turned off, the battery voltage (VBAT) may be blocked from being supplied from the battery (550) to the second connector (C2) (or the second pin (1423)). That is, when the switch (Q2) is turned off, the battery voltage (VBAT) may not be applied to the second pin (1423). Accordingly, when the first pin (1421) is not connected to the PCB (1410), the second pin (1423) may not be carbonized.

[0197] According to one embodiment, when each of the first pin (1421) and the second pin (1423) is connected to the PCB (1410), the switch (Q2) may be turned on by a fourth voltage applied from the battery (550) to the switch (Q2). At this time, the fourth voltage may converge to 0V or 0V by the ground (1435) connected to the first pin (1421). That is, the fourth voltage may be lower than the threshold voltage (or threshold voltage) of the switch (Q2). Based on the switch (Q2) being turned on, the battery voltage (VBAT) may be provided from the battery (550) to the second connector (C2) (or the second pin (1423)). That is, as the switch (Q2) is turned on, power provided from the battery (550) may be provided to the power management circuit (515). Through this, when both the first pin (1421) and the second pin (1423) are connected to the PCB (1410), power (or battery voltage (VBAT)) provided from the battery (550) can be applied to the second pin (1423).

[0198] Based on the above-described method, the electronic device can prevent or minimize the pins of the second connector (C2) from being carbonized even when the connection or engagement between the PCB (1410) and the second connector (C2) is incorrect, without separate control or separate power, by using the protection circuit (1440).

[0199] FIG. 15 is a drawing of electronic devices of various form factors included in a protection circuit according to one embodiment of the present disclosure.

[0200] Referring to (a) of FIG. 15, according to one embodiment, an electronic device (201-2) may include a multi-foldable display. For example, the electronic device (201-2) may include a first housing (1501), a second housing (1502), and a third housing (1503). For example, a first battery (1551) may be placed in the first housing (1501), a second battery (1552) may be placed in the third housing (1503), and a PCB (1530) may be placed in the second housing (1502).

[0201] Referring to (b) of FIG. 15, according to one embodiment, the first housing (1501) and the second housing (1502) can be folded or unfolded using the first hinge (1510).
