Abstract
Description
TECHNICAL FIELD
[0001] The present disclosure relates generally to a flexible circuit board disposed in a foldable electronic device. BACKGROUND
[0002] As the degree of integration of electronic devices has increased and ultra-high speed and large capacity radio frequency (RF) communication has become common, recently it has become to provide a plurality of functions in a single electronic device such as a mobile communication terminal. For example, various functions such as an entertainment function (e.g., a game function), a multimedia function (e.g., a music / video reproduction function), a communication and security function for mobile banking, a dispatch management function, an electronic wallet function, and a communication function can be integrated in a single electronic device. In addition, electronic devices are increasingly equipped with wider display panels so that users have less inconvenience in using multimedia services.
[0003] Recently, a foldable electronic device having a flexible display panel has been developed. The foldable electronic device can refer to an electronic device including a plurality of housing structures that rotate with respect to each other.
[0004] A circuit board disposed in an electronic device can be classified into a rigid circuit board and a flexible circuit board according to physical characteristics related to flexibility. A rigid-flexible circuit board (hereinafter referred to as a "flexible circuit board") in which a rigid circuit board and a flexible circuit board are combined can be provided in order to increase reliability of electrical connection of an electronic device and implement three-dimensional wiring.
[0005] Because of the commercialization of a fourth generation (4G) communication system, in order to meet the increasing demand for wireless data traffic, a fifth generation computer (5G) communication system has been actively developed and released. In order to achieve a high data rate, the 5G communication system uses several tens of gigahertz (GHz) or higher ultra-high frequencies (or referred to as "millimeter wave communication"). However, in an electronic device including an ultra-high frequency communication module, the performance exhibited by the communication module can be affected by a path (e.g., a wiring) through which a communication signal is transmitted due to high frequency characteristics.
[0006] Therefore, for a foldable electronic device, it can be necessary to provide a flexible circuit board capable of preventing degradation of RF characteristics of a signal. SUMMARY
[0007] TECHNICAL PROBLEM
[0008] In an electronic device, various electronic elements (or electronic components) and printed circuit boards on which various electronic elements are mounted can be disposed inside a cradle on which the components are mounted. In the case of a foldable electronic device, the electronic elements and the printed circuit boards can be individually disposed in a plurality of housing structures based on various factors such as a space for installation, communication performance, and heat dissipation performance. A flexible circuit board that is easily bendable can be used to connect the electronic elements.
[0009] Because at least a portion of the flexible circuit board is flexibly bendable, the flexible circuit board can be highly utilized in a narrow space and is suitable for use in a configuration in which electronic elements contained inside a housing structure are connected. However, aspects of durability and lifespan can need to be additionally considered.
[0010] According to some embodiments, when the foldable electronic device is repeatedly folded and unfolded, stress caused by frictional force with the housing, the components, or another board is accumulated in the bent portion of the flexible circuit board, which can result in damage.
[0011] In addition, according to some embodiments, when the bent portion of the flexible circuit board moves within a designated area (i.e., when a designated shape of the bent portion is not maintained), the shape (and / or position) of the bent portion can not be able to be invariably maintained. In addition, the designated shape of the bent portion can be deformed during repeated use of the foldable electronic device, and thus the lifespan can be shortened.
[0012] When the foldable electronic device is equipped with an ultra-high frequency communication module (e.g., ultra-high communication in the range of 6 GHz or more and less than 100 GHz), for example, when a flexible circuit board including an RF signal line is included, because the flexible circuit board designed in consideration of RF characteristics is formed to have a narrower width than a board including a general signal line, it can be difficult to maintain the designated shape of the bent portion. In addition, when the designated shape of the bent portion is deformed without being maintained, the impedance of the flexible circuit board including the RF signal line can change, resulting in a decrease in RF characteristics and an increase in signal loss.
[0013] Various embodiments of the disclosure are capable of providing a foldable electronic device that is capable of maintaining the shape of a flexible circuit board even when the foldable electronic device is repeatedly folded and unfolded, so that damage to the flexible circuit board, a decrease in the lifespan of the flexible circuit board, and deterioration of RF characteristics of the flexible circuit board can be prevented.

The communication module 190 can include one or more communication processors that are operable independently from the processor 120 (e.g., an AP) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 can include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device, via a first network 198 (e.g., a short-range communication network, such as BluetoothTM, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or a second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules can be implemented as a single component (e.g., a single chip), or can be implemented as separate components (e.g., separate chips) from each other. The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0082] The sensor module 209 can generate an electrical signal or data value corresponding to an internal operating state or an external environmental state of the electronic device 101. The electronic device 101 can include another sensor module in addition to the sensor module 209 disposed on the second surface 310b of the first housing 310, or can include another sensor module instead of the sensor module 209. The electronic device 101 can include, for example, at least one of a proximity sensor, a fingerprint sensor, a heart rate monitor (HRM) sensor, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an IR sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor, as the sensor module.

The electronic device 101 can not include some or all of the above-mentioned key input devices 211, 212, and 213, and the key input devices not included in the electronic device 101 can be implemented on the display 200 in another form such as a soft key. The key input device can be configured such that key input is implemented through the sensor module.
[0084] The connector hole 214 can be configured to accommodate a connector (for example, a USB connector) configured to transmit and receive power and / or data to and from an external electronic device, and to accommodate a connector configured to transmit and receive an audio signal to and from an external electronic device in addition to or instead of the connector.
[0085] The foldable housing 300 can include a first housing structure 310, a second housing structure 320, a first rear cover 380, a second rear cover 390, and a hinge structure 440. The foldable housing 300 of the electronic device 101 can be implemented by a combination and / or assembly of different shapes or components. For example, the first housing structure 310 and the first rear cover 380 can be integrally formed, and the second housing structure 320 and the second rear cover 390 can be integrally formed. The term "housing structure" can be a combination and / or assembly including various components of a housing.
[0086] The first housing structure 310 can be connected to the hinge structure, and can include a first surface 310a facing in a first direction and a second surface 310b facing in a second direction opposite the first direction. The second housing structure 320 can be connected to the hinge structure 440, and can include a third surface 320a facing in a third direction and a fourth surface 320b facing in a fourth direction opposite the third direction. The second housing structure 320 can be rotatable with respect to the first housing structure 310 about the hinge structure (or the folding axis A-A').
[0087] The first housing structure 310 and the second housing structure 320 can be disposed on opposite sides (or upper and lower sides) with respect to the folding axis A-A', and can have substantially symmetrical shapes with respect to the folding axis A-A'. The first housing 310 and the second housing 320 can form an angle or a distance therebetween, which can be variable depending on whether the electronic device 101 is in the unfolded state, the folded state, or the intermediate state. Unlike the second housing structure 320, the first housing structure 310 can further include various sensors. However, the first housing structure 310 and the second housing structure 320 can have mutually symmetrical shapes in other regions.
[0088] At least a portion of the first housing structure 310 and at least a portion of the second housing structure 320 can be made of a metal material or a non-metal material having a degree of rigidity selected to support the display 200. The portion made of at least a metal material can provide a ground plane of the electronic device 101, and can be electrically connected to a ground line formed on the printed circuit board 430.
[0089] The first rear cover 380 can be disposed on one side of the folding axis A-A' on the rear surface of the electronic device 101, and can have a substantially rectangular periphery that can be surrounded by the first housing structure 310, for example. Similarly, the second rear cover 390 can be disposed on the other side of the folding axis A-A' on the rear surface of the electronic device 101, and a periphery of the second rear cover 390 can be surrounded by the second housing structure 320.
[0090] The first rear cover 380 and the second rear cover 390 can have substantially symmetrical shapes with respect to the folding axis A-A'. However, the first rear cover 380 and the second rear cover 390 are not necessarily necessarily have mutually symmetrical shapes, and the electronic device 101 can include the first rear cover 380 and the second rear cover 390 having various shapes. Additionally, the first rear cover 380 can be integrally formed with the first housing structure 310, and the second rear cover 390 can be integrally formed with the second housing structure 320.
[0091] The first rear cover 380, the second rear cover 390, the first housing structure 310, and the second housing structure 320 can define a space in which various components (e.g., a printed circuit board or a battery) of the electronic device 101 can be disposed. One or more components can be disposed or visually exposed on the rear surface of the electronic device 101. For example, at least a portion of the sub display 210 can be visually exposed through the first rear cover 380. Additionally, one or more components or sensors can be visually exposed through the first rear cover 380. The sensors can include a proximity sensor and / or a rear camera. One or more components or sensors can be visually exposed through the second rear cover 390.
[0092] The front camera 207 exposed to the front surface of the electronic device 101 through one or more openings or the rear camera 208 exposed through the first rear cover 380 can include one or more lenses, image sensors, and / or ISPs. The flash 209 can include a light emitting diode or a xenon lamp. Two or more lenses (e.g., an infrared camera lens, a wide-angle lens, and a telephoto lens) and image sensors can be disposed on one surface of the electronic device 101.
[0093] Figure 3A represents a fully unfolded state of the display portion, Figure 3B represents a partially unfolded state (or a partially folded state) of the display portion.
[0094] The display portion of the electronic device 101 can include a configuration of a display screen and a configuration connected to the display and moving as a whole with the display. Referring to Figure 3A , the display portion can include the display panel 200c and the touch panel 200d disposed adjacent to the display panel 200c.
[0095] The electronic device 101 can be adjusted to a folded state or an unfolded state. The electronic device 101 can be a "inward folding" type in which the front surface of the electronic device 101 is folded to form an acute angle when viewed in the direction of the folding axis (e.g., Figure 2 , and an "outward folding" type in which the front surface of the electronic device 101 is folded to form an obtuse angle when viewed in the direction of the folding axis. For example, in the electronic device 101, in the inward folding type, in a state in which the electronic device 101 is in a folded state, the first surface 310a can face the third surface 320a, and in a fully unfolded state, the third direction can be the same as the first direction. In another example, in the outward folding type, in a state in which the electronic device 101 is folded, the second surface 310b can face the fourth surface 320b.
[0096] The inward folding type can mean a type in which the display 200 is not exposed to the outside in the fully folded state. The outward folding type can mean a type in which the display 200 is exposed to the outside in the fully folded state. Figure 3B An intermediate state in which the electronic device 101 is partially unfolded in a process in which the electronic device 101 is folded in the inward folding type is illustrated. Hereinafter, for convenience, the electronic device 101 will be described focusing on a state in which the electronic device 101 is folded in the inward folding type, but it should be noted that the descriptions can be applied to a state in which the electronic device 101 is folded in the outward folding type with necessary modifications.
[0097] The display 200 can include a display panel 200c, a polarizing layer 200b disposed on the display panel 200c, and a window member 200a forming an appearance of the display. The display panel 200c, the polarizing layer 200b, and the window member 200a form one display 200, and can be formed of a flexible material. Thus, as Figure 3A As shown in FIG. 2B, when an external force is applied in a state in which the display 200 is unfolded, the display 200 can be bent, as Figure 3B As shown in FIG. 2B, when an external force is applied in a state in which the display 200 is unfolded, the display 200 can be bent, as Figure 3B As shown in FIG. 2B, when an external force is applied in a state in which the display 200 is unfolded, the display 200 can be bent, as Figure 3A As shown in FIG. 2B, when an external force is applied in a state in which the display 200 is unfolded, the display 200 can be bent, as
[0098] The electronic device 101 can detect an input (e.g., a user's input or an input via the input device 150) on a surface of the display 200 using the touch panel 200d. Here, the input recognizable by the touch panel 200d can include not only an input by direct contact with the surface of the display 200, but also an input by hovering. The touch panel 200d can have substantially the same area as the display 200. The touch panel 200d can be disposed on a top surface or a rear surface of the display 200. Figure 3A and Figure 3B A state in which the touch panel 200d is attached to the rear surface of the display 200 is illustrated.
[0099] The display device 200 can be at least partially composed of a material that transmits radio waves or a magnetic field. Because the display 200 can be equipped with a display panel 200c and / or a touch panel 200d, the display 200 can serve as an output device that outputs a screen and as an input device that is provided with a touch screen function. The display panel 200c can include a display element layer (which includes one or more pixels) and a thin film transistor (TFT) layer connected to the display element layer. The display panel 200c can correspond to a panel such as a liquid crystal display (LCD), a light emitting diode (LED), or an organic light emitting diode (OLED), and can display various images according to various operation states of the electronic device 101, an application being executed, and content.
[0100] The touch panel 200d can include various types of touch pieces. For example, various touch panels such as a capacitive touch panel that detects a change in capacitance, a pressure touch panel that detects a position by detecting pressure applied to the panel, an optical touch panel that uses infrared rays, and a transparent electrode type touch panel that uses contact of a transparent conductive film can be used. In addition, various types of input position detection panels such as an electromagnetic resonance type touch panel can be used.
[0101] The window member 200a can serve as a protective film for protecting the display panel 200c. As the protective film, the window member 200a can be made of a material that protects the display panel 200c from external influences (i.e., scratch resistance) and causes less wrinkles even in a folding area when the foldable housing is repeatedly folded and unfolded. A pure polyimide (CPI) film or ultra-thin glass (UTG) can be included as a material of the window member 200a.

[0115] Figure 5 is a view showing a portion of the interior of the electronic device 101 according to the embodiment. Figure 6 is a diagram showing the Figure 5 FIG. 5 is a diagram showing a state in which the hinge structure 540 is removed in the embodiment shown in FIG. Figure 5 and Figure 6 In the embodiment shown, the interior of the electronic device is magnified to focus on the Figure 4 The flexible connecting member 450 is shown when multiple components (eg, the flexible connecting member 450 and the foldable housing 420) are coupled.

[0117] refer to Figure 5 , the flexible connecting member 550 can be positioned across at least a portion of the interior of the first housing structure 310 and at least a portion of the interior of the second housing structure 320. Here, the phrase "positioning the flexible connecting member 550 across the interior of the housing structure" can mean that the flexible connecting member 550, which has a relatively long, elongated shape, is positioned above or below the housing structure. As described above, the housing structure can include a housing and can be assembled in a configuration that includes at least one of a bracket assembly, a printed circuit board, and a battery disposed within the housing. Therefore, the phrase "positioning the flexible connecting member 550 across at least a portion of the interior of the housing structure" can mean that the flexible connecting member 550 is positioned across at least some of the components included in the housing structure. For example, the flexible connecting member 550 can be positioned across at least a portion of the first bracket assembly 523 and at least a portion of the second bracket assembly 524.

In this case, a portion of the flexible connection member 550 can be configured to pass through the opening 540h in the hinge structure 540.
[0120] The plurality of flexible connection members 551 and 552 will be described in detail later in the embodiments of Figure 10 .
[0121] Hereinafter, the movement of the flexible connection member 550 in the hinge space will be described with reference to Figure 7 and Figure 8 . Here, the dotted line B-B' represents a virtual surface perpendicular to the folding axis A-A' shown in Figure 5 and Figure 6 .
[0122] Figure 7 is a cross-sectional view illustrating the hinge structure 540 and the flexible connection member 660 in a state in which the electronic device 500 is unfolded, according to an embodiment. Figure 8 is a cross-sectional view illustrating the hinge structure 540 and the flexible connection member 550 in a state in which the electronic device is folded, according to an embodiment.

The surface of the first area 201 and the surface of the second area 202 of the display can form an angle of approximately 180 degrees therebetween and can face the same direction (e.g., the forward direction of the electronic device). The folding area 203 formed between the first area 201 and the second area 202 can form the same plane as the first area 201 and the second area 202.
[0125] refer to Figure 8 When the electronic device 500 is in the folded state, the first surface 421a of the first shell 510 and the second surface 422a of the second shell 520 are arranged to face each other. The first surface 421a and the second surface 422a can form an acute angle (for example, an angle between approximately 0 degrees and 10 degrees) relative to the virtual plane BB' perpendicular to the folding axis A-A'. The surface of the first area 201 and the surface of the second area 202 of the display can also face each other while forming a narrow angle (for example, an angle between approximately 0 degrees and 10 degrees) with respect to each other. At least a portion of the folding area 203 can have a curved surface having a predetermined curvature.
[0126] refer to Figure 8 , will describe Figure 3B The electronic device 500 is shown in an embodiment in an intermediate state. The first surface 421a of the first housing 510 and the second surface 422a of the second housing 520 can be arranged at a certain angle to each other. The surface of the first area 201 and the surface of the second area 202 of the display 200 can form an angle that is greater than the angle in the folded state and less than the angle in the unfolded state. At least a portion of the folding area 203 can have a curved surface (the curved surface has a predetermined curvature), and the curvature in this state can be less than the curvature in the folded state.
[0127] Reference together Figure 7 and Figure 8 The hinge structure 540 includes a first hinge structure 541 and a second hinge structure 542. Each of the first hinge structure 541 and the second hinge structure 542 may include a hinge plate. The first hinge structure 541 may support at least a portion of the flexible connection member 550, and the second hinge structure 542 may also support at least a portion of the flexible connection member 550. In the above structure, the hinge structure 540 may be coupled to the hinge cover 570 to define a hinge space S at least partially surrounded by the hinge structure 540 and the hinge cover 570.

Each of the first rotation support surface 511a and the second rotation support surface 521a can include a curved surface corresponding to a curved surface included in the hinge cover 570.
[0129] When the electronic device 500 is in an unfolded state (e.g., the embodiment illustrated in FIG. 1A), the first rotation support surface 511a and the second rotation support surface 521a can cover the hinge cover 570 so that the hinge cover 570 cannot be exposed to the rear surface of the electronic device 500 or can be minimally exposed to the rear surface of the electronic device 101. When the electronic device 500 is in a folded state (e.g., the embodiment illustrated in FIG. 1B), the first rotation support surface 511a and the second rotation support surface 521a can be rotated along the curved surface included in the hinge cover 570 so that the hinge cover 570 can be exposed to the rear surface of the electronic device 500. Figure 7 Figure 8
[0130] Figure 9 is a view illustrating a disturbed (e.g., appearing irregular) designated shape of the flexible connection member 650 in a state in which the electronic device is unfolded.
[0131] Referring to Figure 9 , the shape of the flexible connection member 650 in the hinge space S can be disturbed due to repeated operations of folding and unfolding the foldable electronic device. The expression "designated shape is disturbed" can include a case in which the designated shape of the flexible connection member 650 is permanently deformed, or a case in which the shape of the flexible connection member 650 is deformed due to the foldable electronic device being repeatedly folded and unfolded.
[0132] According to an example in which the designated shape is disturbed, when a plurality of flexible connection members are disposed in the hinge space S, the designated shape of each flexible connection member 650 can be more easily disturbed, and disturbance to the designated shape of any one flexible connection member can affect signal transmission performance and the service life of other flexible connection members.
[0133] Referring to Figure 9 When the designated shape of the two flexible connection members 651 and 652 is not maintained while the electronic device is in the unfolded state, at one side P1 of the hinge side S, the flexible connection members 651 and 652 can come into excessive close contact with the structure (e.g., the hinge cover 670) side of the foldable electronic device. On the other side P2, at least one of the flexible connection members 651 and 652 can come into excessive close contact with the structure (e.g., the hinge cover 670) side of the foldable electronic device, and can be spaced apart from the other flexible connection member. If the designated shape of the two flexible connection members 651 and 652 is not maintained, the shape of the flexible connection members 651 and 652 at one side P1 and the shape of the flexible connection members 651 and 652 at the other side P2 can be different from each other. Furthermore, in another portion P3, the flexible connection members 651 and 652 can rub against the structure (e.g., the hinge cover 670) of the foldable electronic device while the electronic device is in the unfolded state, which can cause damage due to accumulated stress or rapid reduction in the service life.
[0134] In the following description, various embodiments for preventing the designated shape of the flexible connection member from being disturbed will be described.
[0135] First, various embodiments of the flexible connection member 550 will be described. Figure 10 is a view showing a flexible connection member according to an embodiment.
[0136] Referring to Figure 10 , the flexible connection member 550 can include a plurality of flexible connection members. For example, the flexible connection member 550 can include a first flexible connection member 551 and a second flexible connection member 552. In addition, the flexible connection member 550 can further include three or more flexible connection members.
[0137] In Figure 10 , the first flexible connection member 551 and the second flexible connection member 552 are completely separated from each other and are illustrated as two separate flexible connection members.
[0138] Basically, one flexible connection member can be divided into a first flexible connection member 551 and a second flexible connection member 552. For example, one flexible connection member which is not physically divided basically can be divided into a first flexible connection member 551 and a second flexible connection member 552 according to the type of a signal line, and can be branched into two or more branches in some areas where the flexible connection member is located only. The first flexible connection member 551 and the second flexible connection member 552 can have the form of an integrated flexible connection member inside the first housing structure 310, and can be branched into two different flexible connection members 551 and 552 inside the second housing structure 320. As described above, it should be noted that the shape of the flexible connection member can be variously provided in different embodiments. In the following description, for the convenience of description, the case where two flexible connection members 551 and 552 which are physically spaced apart from each other and have different shapes will be described, but it should be noted that the scope of the present disclosure is not necessarily limited thereto.
[0139] Referring to Figure 10 The first flexible connection member 551 can be placed across at least a portion of the inside of the first housing structure 310 and at least a portion of the second housing structure 320. The second flexible connection member 552 can also be placed across at least a portion of the first housing structure 310 and at least a portion of the second housing structure 320.
[0140] Each of the first and second flexible connection members 551 and 552 can include a means to connect to the first or second printed circuit board 431 or 432. The first flexible connection member 551 can electrically connect the first and second printed circuit boards 431 and 432 via connection ends 551a and 551b disposed at opposite ends thereof. The second flexible connection member 552 can also electrically connect the first and second printed circuit boards 431 and 432 via connection ends 552a and 552b disposed at opposite ends thereof. Here, the connection ends can each include a receptacle or header in which at least one pin is formed. The first and second flexible connection members 551 and 552 can be connected to at least one of the first and second printed circuit boards via various other means as well as the receptacle or header configuration. For example, the flexible connection members 551 and 552 can be connected to at least one of the first and second printed circuit boards 431 and 432 via soldering using a hot-bar process formed by hot-bar soldering. The shape of the connection ends and the method of manufacturing thereof are not limited to any particular configuration. Based on the shape of the connection ends, the first and second flexible connection members 551 and 552 can include, for example, a flexible printed circuit (FPC) or flexible flat cable (FFC) type connector configuration, a board-to-board (B-to-B) type connector configuration, a zigzag type connector configuration, a solder type connector configuration formed by a hot-bar soldering process, a low insertion force (LIF) connector configuration, or a zero insertion force (ZIF) connector configuration.
[0141] Each of the first and second flexible connection members 551 and 552 can include at least one conductive path connecting the first and second printed circuit boards 431 and 432 to each other. Power or control signals provided from the power management module or the processor can be transmitted via the conductive path. The flexible connection members 551 and 552 can each include an RF wire (which is a high frequency signal line) as a conductive path for transmitting a communication signal provided from an RF transceiver or received via a communication device to another RF transceiver. For example, the first flexible connection member 551 can include a wire (or conductive path) for transmitting a communication signal including an RF signal. Also, the second flexible connection member 552 can include a wire for transmitting an electrical signal less sensitive to impedance variation than the wire included in the first flexible connection member 551. The second flexible connection member 552 can include a power line. In addition to or instead of the power line, the second flexible connection member 552 can include a wire for transmitting data and / or a wire (conductive path) for transmitting a control signal. Depending on the RF signal characteristics, the first flexible connection member 551 can be formed thinner and narrower than the second flexible connection member 552. Thus, when the first flexible connection member 551 including a conductive path for transmitting an RF signal is repeatedly used in a state in which its designated shape is disturbed in the hinge space, the durability of the first flexible connection member 551 will be relatively weak compared to the second flexible connection member 552, and it can be difficult to exhibit a smooth communication performance because the first flexible connection member 551 is vulnerable to impedance variation.
[0142] Figure 11 is a view illustrating a flexible connection member and an adhesive member according to an embodiment.
[0143] Referring to Figure 11 The foldable electronic device includes an adhesive member 553 attached to the first flexible connection member 551. The adhesive member 553 can be a component for maintaining the first flexible connection member 551 in a constant shape within a designated area when the foldable housing 300 is folded and unfolded. A tape portion (e.g., an insulating tape portion) can be used as the adhesive member 553. The first and second flexible connection members 551 and 552 can maintain their designated shapes through the adhesive member 553 even when the foldable electronic device is repeatedly folded and unfolded.
[0144] The adhesive member 553 can be disposed to cover at least a partial area of the first flexible connection member 551. Here, the portion 450c (or "flexible portion") of the flexible connection member described with reference to Figure 4 may correspond to the "at least partial area" of the first flexible connection member 551.
[0145] Each portion of the flexible connection member will be described. Reference is made toFigure 10 and Figure 11 The first flexible connection member 551 can include a rigid portion 551c fixed to the first housing structure 310 side, a rigid portion 551d fixed to the second housing structure 320, and a flexible portion 551e between the rigid portion 551c and the rigid portion 551d along the longitudinal direction of the first flexible connection member 551. The second flexible connection member 552 can include a rigid portion 552c fixed to the first housing structure 310 side, a rigid portion 552d fixed to the second housing structure 320, and a flexible portion 552e between the rigid portion 552c and the rigid portion 552d along the longitudinal direction of the flexible connection member 551. Here, the wording "the rigid portion 551c and the rigid portion 551d of the first flexible connection member 551 are fixed to the first housing structure side and the second housing structure side" can include the case where the rigid portion 551c of the first flexible connection member 551 is fixed to the first hinge structure 441, the first printed circuit board 431, or the first cradle assembly 423 arranged inside the first housing structure 310. The rigid portion 551d of the first flexible connection member 551 can be fixed to the second hinge structure 442, the second printed circuit board 432, or the second cradle assembly 424 arranged inside the second housing structure 320. The wording "the rigid portion 552c and the rigid portion 552d of the second flexible connection member 552 are fixed to the first housing structure side and the second housing structure side" can be similarly applied to the embodiment in which the rigid portion 551c and the rigid portion 551d of the first flexible connection member 551 are fixed to the first housing structure side and the second housing structure side.
[0146] The flexible portions 551e and 552e can be portions movable in a space inside the hinge structure (for example, the hinge space S in FIG. 11). The adhesive member 553 can be stacked on the flexible portion 551e of the first flexible connection member 551 and can guide the flexible portion 551e to be movable within a designated area (for example, the hinge space S) while maintaining its shape (and / or position) unchanged. Figure 7
[0147] The first flexible connection member 551 can include a cover layer in order to improve the rigidity of the first flexible connection member 551 and thus maintain the designated shape of the flexible connection member 551. However, when the cover layer is added to the first flexible connection member 551, the flexibility of the flexible portion 551e can decrease. Accordingly, an embodiment can be provided which maintains the designated shape of the first flexible connection member 551 without the cover layer using the adhesive member 553.
[0148] Figure 12 is a view illustrating a flexible connection member and an adhesive member 554 connecting the flexible connection member according to an embodiment. Figure 13 is a view showing a state in which one or more slits 555 are formed in the adhesive member 554 according to an embodiment.
[0149] Referring to Figure 12 , the foldable electronic device includes an adhesive member 554 connecting the flexible connection members 551 and 552 to each other. The adhesive member 554 can be a component configured to fix the positions of the two different flexible connection members 551 and 552 together and to maintain the specified shapes (and / or positions) of the first flexible connection member 551 and the second flexible connection member 552 unchangeably within a specified area when the foldable housing 300 is folded and unfolded. The adhesive member 554 can serve to connect the first flexible connection member 551 and the second flexible connection member 552 as if they are a single flexible connection member.
[0150] The first flexible connection member 551 and the second flexible connection member 552 can be connected to each other using a tape portion as the adhesive member 554. The first flexible connection member 551 and the second flexible connection member 552 can maintain their specified shapes through the adhesive member 554 even when the foldable electronic device is repeatedly folded and unfolded.
[0151] Referring to Figure 13 , the adhesive member 554 can be disposed to cover at least a partial area of the first flexible connection members 551 and 552. Here, the portion (or "flexible portion") 450c of the flexible connection member described above with reference to Figure 4 may correspond to the "at least partial area" of the flexible connection members 551 and 552. Hereinafter, with respect to each portion of the adhesive member 554, the description of the portion repeated with respect to Figure 11 will be omitted.
[0152] The flexible portions 551e and 552e can be portions movable in a space inside the hinge structure (e.g., the hinge space S in Figure 7 ). The adhesive member 554 can be stacked on the flexible portions 551e of the first flexible connection member 551 and 552e of the second flexible connection member 552 and can guide the flexible portions 551e and 552e to be movable within a specified area (e.g., the hinge space S) while maintaining their shapes (and / or positions) unchangeable.
[0153] Referring to Figure 13The opposite side of the adhesive member 554 can be connected to the rigid portions 551c and 551d of the first flexible connection member 551 and the rigid portions 552c and 552d of the second flexible connection member 552, respectively. For example, the adhesive member 554 can have a shape that completely covers the flexible portions 551e and 552e. Alternatively, the adhesive member 554 can have a shape that covers only a portion of the flexible portions 551e and 552e.
[0154] The shape of the adhesive member 554 can be variously set. For example, in addition to completely covering the portions of the flexible portions 551e and 552e, the adhesive member 554 can include a handle portion 553a that allows a user to directly attach the adhesive member 554 to the first and second flexible connection members 551 and 552.
[0155] One or more slits can be formed in the adhesive member 554 to maintain a designated shape of the flexible connection members 551 and 552. One or more slits 555 can be used to equalize movement of the flexible portions when the flexible connection members 551 and 552 are bent.
[0156] A longitudinal direction of the one or more slits 555 can be parallel to the folding axis A-A' of the electronic device 101. When a plurality of slits are included, the arrangement direction of the plurality of slits can be formed perpendicular to the folding axis A-A'.
[0157] Figure 14 FIG. 5B is a view illustrating a state in which the flexible connection members 551 and 552 and the adhesive member 554 are coupled to each other according to an embodiment.
[0158] Referring to Figure 14 In the adhesive member 554, a handle part 554a included in the adhesive member 554 can be disposed at different portions of the adhesive member 554 to form different shapes of the adhesive member 554. In contrast to Figure 13 In contrast, only one side of the adhesive member 554 is connected to the rigid portions 551d and 552d of the first and second flexible connection members 551 and 552, and the other side is stacked on the flexible portions 551e and 552e in a state spaced apart from the rigid portions 551c and 552c by a predetermined distance.
[0159] In addition, the shape and / or number of one or more slits 555 provided in the adhesive member 554 can vary. In the following description of Figure 15A to Figure 15E According to various embodiments, one or more slits are disclosed.
[0160] Figure 15A FIG. 5B is a view illustrating a state in which the flexible connection members 551 and 552 and the adhesive member 554 are coupled to each other according to an embodiment. Figure 15Bis a view showing the shape of one or more slits 555 according to an embodiment. Figure 15C is a view showing the shape of one or more slits 556 according to an embodiment. Figure 15D is a view showing the shape of one or more slits 557 according to an embodiment. Figure 15E is a view showing the shape of one or more slits 557 and 558 according to an embodiment.
[0161] The one or more slits formed in the adhesive member 554 can have various forms, numbers, and various widths and lengths. For example, as shown in Figure 15A , a plurality of slits 555 having the same width t and length l can be formed in the adhesive member 553, and the intervals d1 and d2 between the slits can be variously set according to the positions of the slits provided in the adhesive member 554. The slits close to the center of the adhesive member 554 can have a small interval d1 so that the slits are densely arranged, and the slits away from the center can have a relatively large interval d2 so that the density of the slits is relatively sparsely arranged.
[0162] Alternatively, as shown in Figure 15B , a plurality of slits 555 having different widths t1 and t2 or different lengths can be formed in the adhesive member 554. For example, narrow slits 555a can be arranged close to the center of the adhesive member 554, and relatively wide slits 555b can be arranged away from the center of the adhesive member 554.
[0163] Alternatively, as shown in Figure 15C , the one or more slits 556 can have a very narrow width like a thin line shape and a very long length compared to the width. Some of the one or more slits 556 can extend to the handle portion 554a.
[0164] Alternatively, as shown in Figure 15D , a cross-shaped pattern can be repeated in the form of at least one slit 557.
[0165] Alternatively, as shown in Figure 15E , one or more slits 557 and 558 having two or more different shapes can be used in combination. Among the one or more slits 557 shown in Figure 15E , some slits 557 can adopt a cross-shaped pattern, and the other slits 558 can adopt an open shape pattern formed by punching.
[0166] Additionally, the one or more slits can include a reference Figure 15A to Figure 15EVarious embodiments other than the described embodiments. When one or more slits are capable of acting to make the movement of the flexible portion uniform as the flexible connection members 551 and 552 are bent, the slits can include similar patterns such as holes, grooves, notches, and openings.
[0167] In the above-described embodiments, the adhesive member for maintaining a designated shape when two or more flexible connection members are bent and the slit structure formed therein have been described. Hereinafter, the description will focus on the slit structure for maintaining a designated shape when a multi-layer flexible connection member is bent.

Figure 17 is a conceptual view illustrating a flexible connection member 750 and one or more slits 755 formed in the flexible connection member 750 according to an embodiment. Figure 18A is a view illustrating a cross-sectional view of a flexible connection member 750 and one or more slits 755 formed in the flexible connection member according to an embodiment. Figure 17 is a view illustrating a cross-sectional view of a flexible connection member 750 and one or more slits 755 formed in the flexible connection member according to an embodiment. Figure 18B is a view illustrating a cross-sectional view of a flexible connection member 750 and one or more slits 755 and 755' formed in the flexible connection member according to an embodiment. Here, Figure 18A and Figure 18B each illustrate a cross-sectional view of a flexible connection member 750 according to an embodiment taken in the direction of line C-C'. Figure 17 is a view illustrating a cross-sectional view of a flexible connection member 750 according to an embodiment.
[0169] The flexible connection member 750 can be substantially formed of one flexible connection member. Referring to Figure 16 , the flexible connection member 750 can be made as a single flexible connection member, and include a plurality of connection ends 750aa, 750ab, 750ba, and 750bb branched out from at least one of the first and second housing structures 310 and 320. Figure 16 The flexible connection member 750 illustrated in
[0170] Referring to Figure 17The flexible connection member 750 includes rigid portions 750c and 750d fixed to the housing, the bracket assembly, or the printed circuit board along the longitudinal direction thereof. In addition, a flexible portion 750e can be disposed between the rigid portions 750c and 750d. Here, when the flexible connection member 750 is installed inside the foldable housing 420 or the foldable housing structure 330, the flexible portion 750e can be disposed in a hinge space S surrounded at least partially by the hinge structure 440 and / or the hinge cover 470.
[0171] Referring to Figure 18A and Figure 18B The flexible portion 750e of the flexible connection member 750 has a plurality of layered structures. In addition, at least one slit 755 can be formed in the outermost layer of the plurality of layered structures, for example, in the uppermost layer and / or the lowermost layer. Figure 18A A plurality of slits 755 formed in the uppermost layer of the flexible connection member 750 is illustrated. As Figure 18B indicated, a plurality of slits 755 can be formed in the uppermost layer of the flexible connection member 750, and a plurality of slits 755' can also be formed in the lowermost layer.
[0172] The flexible connection member 750 can include a plurality of conductive layers and a plurality of insulating layers as the plurality of layered structures. The plurality of conductive layers and the plurality of insulating layers included in the flexible portion 750e can integrally extend from the rigid portions 750c and 750d. The flexible portion 750e can include a first cover layer 751, a stacked structure 752 of at least one conductive layer and at least one insulating layer, and a second cover layer 753. Here, the stacked structure 752 of at least one conductive layer and at least one insulating layer can be a first conductive layer, a first insulating layer, a second conductive layer, and a second insulating layer sequentially stacked. At least a portion of the flexible connection member 750 (for example, the upper surface of the first conductive layer) can be visible to the outside, and can be covered by the first cover layer 751. Similarly, the lower end of the flexible connection member 750 can also be covered by the second cover layer 752. By forming a slit 755 in at least one of the first cover layer 751 and the second cover layer 753, for example, by forming one or more slits in a portion corresponding to a hinge structure (or a hinge space) in the multi-layered flexible connection member, a designated shape can be maintained when the multi-layered printed circuit board is bent. Accordingly, the service life of the flexible connection member can be improved.
[0173] One or more slits 755 can also be formed in a direction parallel to the folding axis A-A'. In addition, the one or more slits 755 can also have various shapes, numbers, and various widths and lengths similar to the slits formed in the adhesive member 553.
[0174] Figure 19is a view illustrating a flexible connection member 950 according to an embodiment and one or more slits formed in the flexible connection members 951 and 952.
[0175] Referring to Figure 19 , the multi-layer flexible connection member includes a first multi-layer flexible connection member 951 disposed across at least a portion of the first housing structure 310 and at least a portion of the second housing structure 320 and configured to electrically connect the first printed circuit board 431 and the second printed circuit board 432 via connection ends located at opposite ends of the first multi-layer flexible connection member 951, and a second multi-layer flexible connection member 952 disposed across at least a portion of the first housing structure 310 and at least a portion of the second housing structure 320 and configured to electrically connect the first printed circuit board 431 and the second printed circuit board 432 via connection ends arranged at opposite ends of the second multi-layer flexible connection member 952.
[0176] One or more slits 955 and 956 can be formed in each of the first multi-layer flexible connection member 951 and the second multi-layer flexible connection member 952. The one or more slits 955 and 956 can be formed in at least one of the uppermost layer and the lowermost layer of the first multi-layer flexible connection member 951, and can be formed in at least one of the uppermost layer and the lowermost layer of the second multi-layer flexible connection member 951. The one or more slits 955 and 956 can be formed in a portion of at least one of the uppermost layer and the lowermost layer of the first multi-layer flexible connection member 951, for example, between the rigid portions 951c, 952c, 951d, and 952d.
[0177] As Figure 19 indicated in the above, when a plurality of multi-layer flexible connection members are provided, the specified shape of the multi-layer flexible connection members can be maintained by forming one or more slits in each of the multi-layer flexible connection members.
[0178] In the case where a plurality of flexible connection members are provided in the foldable housing, the method of maintaining the specified shape using the adhesive member 553 described above with reference to Figure 10 to Figure 15E may be applied together, and the method of forming the slit directly in the multi-layer flexible connection member described above with reference to Figure 16 to Figure 18B may be applied.
[0179] Figure 20 is a view illustrating a state in which the specified shape of the flexible connection member 1051 is maintained when the foldable electronic device is unfolded according to an embodiment.
[0180] Referring to Figure 20When the adhesive member 1053 is attached to the first flexible connection member 1051, it can be seen that the designated shape of the first flexible connection member 1051 is maintained even when the foldable electronic device is repeatedly folded and unfolded.
[0181] With Figure 20 comparing the embodiment shown in Figure 9 , it can be seen that the uniformity of the designated shape of the first flexible connection member 1051 is significantly improved in the embodiment shown in Figure 9 , for example, in the embodiment shown in Figure 20 , it can be seen that the designated shape of the first flexible connection member 1051 is not disturbed in the portion corresponding to P1 in Figure 20 , in addition, in the embodiment shown in Figure 9 , it is possible to prevent or significantly reduce friction with the structure (e.g., the hinge cover 1070) of the foldable electronic device. Figure 20
[0182] Figure 21 is a view showing a state in which the designated shapes of the flexible connection members 1151 and 1152 are maintained when the foldable electronic device is unfolded according to an embodiment.
[0183] Referring to Figure 21 , when the adhesive member 1154 is attached on two different flexible connection members 1151 and 1152, the designated shapes of the flexible connection members 1151 and 1152 are maintained even when the foldable electronic device is repeatedly folded and unfolded. In addition, by forming a plurality of slits 1155 in the adhesive member 1154, the uniformity of the designated shapes of the flexible connection members 1151 and 1152 can be further improved. When Figure 21 comparing the embodiment shown in Figure 9 , it can be seen that the uniformity of the designated shapes of the first flexible connection member 1151 and the second flexible connection member 1152 is significantly improved in the embodiment shown in Figure 9 , for example, in the embodiment shown in Figure 21 , it can be seen that the designated shapes of the first flexible connection member 1151 and the second flexible connection member 1152 are not disturbed in the portion corresponding to P1 in Figure 21 , in addition, in the embodiment shown in Figure 9 , it is possible to prevent or significantly reduce friction with the structure (e.g., the hinge cover 1170) of the foldable electronic device. Figure 21
[0184] Figure 22 is a view showing a state in which the designated shape of the flexible connection member 1250 is maintained when the foldable electronic device is unfolded according to an embodiment.
[0185] Referring to Figure 22 , the flexible connection member 1250 is a multi-layer flexible connection member 1250. When the foldable electronic device is repeatedly folded and unfolded, the stack portion of the multi-layer flexible connection member 1250 can be separated and the designated shape can be disturbed. To prevent this, by forming one or more slits 1255 in at least one outermost layer of the multi-layer flexible connection member 1250, as described above, it can be seen that the designated shape of the plurality of flexible connection members 1250 is maintained even when the foldable electronic device is repeatedly folded and unfolded. For example, in the embodiment shown in Figure 22 , it can also be seen that the designated shape of the first flexible connection member 1250 is not disturbed. Furthermore, in the embodiment shown in Figure 22 , friction with the structure (e.g., the hinge cover 1270) of the foldable electronic device can be prevented or significantly reduced.
