Description
Adhesive structure and electronic device including same
[0001] The present disclosure relates to an adhesive structure and an electronic device including the same.
[0002] Thanks to remarkable advancements in information and communication technology and semiconductor technology, the proliferation and use of various electronic devices is rapidly increasing. In particular, recent electronic devices are being developed to enable portable communication.

[0004] For example, these electronic devices can output stored information as audio or video. As electronic device integration increases and ultra-high-speed, high-capacity wireless communications become more widespread, a single electronic device, such as a mobile terminal, can now be equipped with a variety of functions. For example, in addition to communication functions, entertainment functions such as gaming, multimedia functions such as music and video playback, communication and security functions for mobile banking, and even functions such as schedule management and electronic wallets are being integrated into a single electronic device. These electronic devices are also becoming smaller for convenient portability.
[0005] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

The conductive adhesive sheet may be formed to adhere to the conductive structure. The conductive structure and the conductive adhesive sheet may be formed such that when a voltage is applied to the conductive structure and the conductive adhesive sheet, an adhesive force between the conductive structure and the conductive adhesive sheet decreases.
[0007] An electronic device according to one aspect of the present disclosure may include a housing; a cover disposed on the housing and having a conductive structure coupled along an edge thereof; a circuit board positioned within the housing; and a conductive adhesive sheet disposed along an edge of the housing, having a shape corresponding to the conductive structure, and configured to adhere to the conductive structure.

These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0117] According to one embodiment, the conductive adhesive sheet (340) may be named at least one of an electrical release sheet / electrical peel-off sheet, a current-carrying adhesive sheet, or an electrical adhesive sheet. The expression adhesive may be replaced with at least one of sticky, glue, paste member, or waterproof. The expression sheet may be replaced with at least one of tape, film, member, part, portion, or component of an element.
[0118] According to one embodiment, the conductive adhesive sheet (340) may include a second connection portion (340a) adhered to the side wall (312) of the housing (310), and a second extension portion (340b) extending from the second connection portion (340a) toward the inside of the circuit board (240). The second extension portion (340b) may be a portion (e.g., a section or a specific area) for electrically connecting to the second contact element (262) and may extend to contact the second contact element (262) disposed on the circuit board (240).
[0119] The conductive structure (330) and the conductive adhesive sheet (340) disclosed in FIGS. 6 and 7 are disclosed as structures arranged along all edges of the protective cover (320) and / or the housing (700), but are not limited thereto and may be designed in various shapes, such as an open loop with one side opened.
[0120] FIG. 8 is a perspective view showing an area inside an electronic device with a protective cover excluded, according to one embodiment of the present disclosure.
[0121] FIG. 9 is a cross-sectional view showing a laminated state of an adhesive structure in one area of an electronic device according to one embodiment of the present disclosure.
[0122] FIG. 10 is a cross-sectional view taken along line A-A' of a portion of the electronic device of FIG. 8 according to one embodiment of the present disclosure.
[0123] FIG. 11 is a cross-sectional view taken along line B-B' of a portion of the electronic device of FIG. 8 according to one embodiment of the present disclosure.
[0124] The components of the electronic device (101) of FIGS. 8 to 11 may be partially or entirely identical to the components of the electronic device (101) of FIGS. 1 to 7.
[0125] The embodiments of FIGS. 8 to 11 can be optionally combined with the embodiments of FIGS. 1 to 7 and the embodiments of FIGS. 12 to 24.
[0126] According to one embodiment, the electronic device (101) may include at least one of a housing (310), a protective cover (320), a circuit board (240), a battery (250), a conductive structure (330), and / or a conductive adhesive sheet (340).
[0127] According to one embodiment, the adhesive structure can bond the housing (310) and the protective cover (320) with a strong adhesive force. According to one embodiment, when voltage is applied to the electronic device (101) for disassembly of the electronic device (101) (e.g., protective cover detachment mode), the adhesive force of the adhesive structure is weakened, so that the protective cover (320) can be easily detached from the housing (310).
[0128] According to one embodiment, the adhesive structure may place a conductive adhesive sheet (340) containing an adhesive component between the housing (310) and the protective cover (320) to strengthen the adhesive force. The adhesive structure may laminate a conductive adhesive sheet (340) containing a separable charge for electric peeling characteristics and a conductive structure (330) forming a passage for the charge to move, to weaken the adhesive force.
[0129] According to one embodiment, the side wall (312) of the housing (310) may include a first side wall portion (312a) forming an outer side (e.g., an outer surface) of the electronic device (101) and a second side wall portion (312b) extending inwardly from the first side wall portion (312a) of the electronic device (101). The second side wall portion (312b) is formed to surround an edge of a support plate (311) of the housing (310), and a rear side (e.g., a side) (e.g., a side facing the -Z axis) may provide a side (e.g., a side) on which a conductive adhesive sheet (340) adheres to the housing (310). The first side wall portion (312a) and the second side wall portion (312b) may have a stepped (e.g., a step) shape.
[0130] According to one embodiment, the adhesive structure may be a structure in which a conductive adhesive sheet (340), a conductive structure (330), and a protective cover (320) are sequentially laminated on a second side wall portion (312b) of the housing (310). The first side wall portion (312a) of the housing (310) may be formed to surround the outer side (e.g., surface) of the conductive adhesive sheet (340), the conductive structure (330), and the protective cover (320).
[0131] According to one embodiment, the conductive adhesive sheet (340) may include an adhesive substrate layer (341), a conductive layer (342), and an electrolyte layer (343). The adhesive substrate layer (341), the conductive layer (342), and the electrolyte layer (343) may have a general (e.g., overall) closed loop shape corresponding to each other. The adhesive substrate layer (341), the conductive layer (342), and / or the electrolyte layer (343) may each include an extended portion (e.g., a first extended portion (330b)) that protrudes toward the circuit board (240) (e.g., toward the X-axis direction) to be connected to the contact element (260).
[0132] According to one embodiment, the adhesive substrate layer (341) of the conductive adhesive sheet (340) may be disposed between the housing (310) (e.g., the second side wall portion (312b)) and the conductive layer (342). The adhesive substrate layer (341) may provide a support layer function for supporting the conductive adhesive sheet (340) as a whole (e.g., generally). The adhesive substrate layer (341) may provide an adhesive (e.g., attachment, bonding) function, for example, a pressure-sensitive adhesive function, for adhering the conductive adhesive sheet (340) to the housing (310) and the conductive layer (342). For example, the adhesive substrate layer (341) may be a double-sided adhesive layer, one side (e.g., a side) of which may be adhered to the second side wall portion (312b) of the housing (310), and the other side (e.g., a side) of which may remain adhered to the conductive layer (342). The adhesive substrate layer (341) is constantly combined with the housing (310) and the conductive layer (342), so that even if voltage is applied to the conductive adhesive sheet (340) to separate the housing (310) and the protective cover (320), the adhesive substrate layer (341) can continuously maintain the combined state of the housing (310) and the conductive layer (342). The adhesive substrate layer (341) may have a large thickness compared to other layers of the conductive adhesive sheet (340) (e.g., the conductive layer (342) and / or the electrolyte layer (343)).
[0133] According to one embodiment, the conductive layer (342) of the conductive adhesive sheet (340) may be disposed between the adhesive substrate layer (341) and the electrolyte layer (343). The conductive layer (342) is a layer for the movement of charges constituting the electrolyte layer (343) and may provide a current-conducting function like a metal. For example, if voltage is applied to the conductive adhesive sheet (340), the conductive layer (342) assumes either a (-) pole or a (+) pole, and some of the charges of the electrolyte layer (343) may move toward the conductive layer (342). The conductive layer (342) may remain adhered to the adhesive substrate layer (341) due to the adhesive properties of the adhesive substrate layer (341). The conductive layer (342) may have a small thickness compared to other layers of the conductive adhesive sheet (340) (e.g., the adhesive substrate layer (341) and / or the electrolyte layer (343)).
[0134] According to one embodiment, the electrolyte layer (343) of the conductive adhesive sheet (340) may be disposed between the conductive layer (342) and the protective cover (320). According to one embodiment, the electrolyte layer (343) of the conductive adhesive sheet (340) may be disposed between the conductive layer (342) and the conductive structure (330).
[0135] In one embodiment, the electrolyte layer (343) may include an electrolyte to provide electrical peeling properties, and an adhesive function for bonding the conductive adhesive sheet (340) to the conductive layer (342) and the conductive structure (330) (or the protective cover (320)), for example, the function of a pressure-sensitive adhesive.
[0136] According to one embodiment, the electrolyte layer (343) includes a material that is dissolved in a solvent and dissociates into ions to have electrical conductivity, and may be in a state in which (+) charges and (-) charges are mixed and distributed. The electrolyte layer (343) may be in a solid electrolyte or gel electrolyte state. If voltage is applied to the conductive adhesive sheet (340) to separate the housing (310) and the protective cover (320), the electrolyte layer (343) may separate the (+) charges and (-) charges, thereby allowing the conductive adhesive sheet (340) and the conductive structure (330) to be easily separated.
[0137] According to one embodiment, the electrolyte layer (343) is a double-sided adhesive layer, one side of which is adhered to the conductive layer (342), and the other side of which is maintained in a state of being adhered to the conductive structure (330). The electrolyte layer (343) can provide a property (e.g., electrical peeling property) in which the adhesive strength changes by applying a voltage.
[0138] According to one embodiment, the conductive structure (330) may be disposed between the protective cover (320) and the electrolyte layer (343) of the conductive adhesive sheet (340). The conductive structure (330) may provide a conductive function, such as a metal, as a layer for the movement of charges constituting the electrolyte layer (343). For example, if voltage is applied to the conductive structure (330), the conductive structure (330) may assume either a (-) pole or a (+) pole, and some of the charges of the electrolyte layer (343) may move toward the conductive structure (330). The conductive structure (330) may remain strongly bonded to the protective cover (320), and thus, may provide one side (e.g., a surface) that is separated from the conductive adhesive sheet (340) when the housing (310) and the protective cover (320) are separated.
[0139] According to one embodiment, the conductive adhesive sheet (340) and the conductive structure (330) may each include portions extending toward the circuit board (240) for voltage application. The conductive layer (432) of the conductive structure (330) and the conductive adhesive sheet (340) may have polarity when voltage is applied. For example, the conductive structure (330) may include a first connecting portion (330a) arranged along an edge of the protective cover (320), and a first extending portion (330b) extending from one side of the first connecting portion (330a) to the first contact element (261). For example, the conductive adhesive sheet (340) may include a second connecting portion (340a) arranged along an edge of a side wall of the housing (310), and a second extending portion (340b) extending from one side of the second connecting portion (340a) to the second contact element (262).
[0140] According to one embodiment, the second extension portion (340b) of the conductive adhesive sheet (340) and the first extension portion (330b) of the conductive structure (330) have corresponding shapes and can be arranged in parallel. According to one embodiment, since the conductive structure (330) is a structure laminated on the conductive adhesive sheet (340), the distance between the first extension portion (330b) and the circuit board (240) can be greater than the distance between the second extension portion (340b) and the circuit board (240). However, the shapes of the first extension portion (330b) and the second extension portion (340b) and / or the distance between the circuit board (240) can be variously designed and changed depending on the arrangement and shape of the first contact element (261) and the second contact element (262). According to one embodiment, the second extension portion (340b) of the conductive adhesive sheet (340) and the first extension portion (330b) of the conductive structure (330) may be arranged so as not to overlap when viewed from the protective cover (320) (e.g., in the + Z-axis direction).
[0141] According to one embodiment, one end of the second extension portion (340b) of the conductive adhesive sheet (340) may be arranged to face the second contact element (262) arranged on the circuit board (240). When voltage is applied through the circuit board (240), the conductive layer (342) of the conductive adhesive sheet (340) and the second contact element (262) may be formed in a state where the conductive layer (342) and the second contact element (262) are substantially in contact, for electrical connection between them.
[0142] According to one embodiment, in the second extension portion (340b) of the conductive adhesive sheet (340), the length of the conductive layer (342) and the adhesive substrate layer (341) may be longer than the length of the electrolyte layer (343). The conductive adhesive sheet (340) may be laminated with the conductive layer (342) and the electrolyte layer (343) in the -Z-axis direction based on the adhesive substrate layer (341). In order for the conductive layer (342) disposed between the adhesive substrate layer (341) and the electrolyte layer (343) to contact the second contact element (262), a portion thereof needs to be exposed to the outside of the portion covered by the electrolyte layer (343), and the length of the conductive layer (342) is designed to be longer than the length of the electrolyte layer (343), so that a portion thereof can contact the second contact element (262).
[0143] According to one embodiment, in the second extended portion (340b) of the conductive adhesive sheet (340), the length of the conductive layer (342) may be longer than the lengths of the adhesive substrate layer (341) and the electrolyte layer (343). In the second extended portion (340b) of the conductive adhesive sheet (340), the electrolyte layer (343) is adhered (e.g., attached or bonded) to the protective cover (320) via the conductive structure (330), and the conductive layer (342) and the adhesive substrate layer (341) that are extended longer than the electrolyte layer (343) may form a bent section. In the above-mentioned bent section, the adhesive substrate layer (341) is placed facing (e.g., facing or in an opposite direction) and adhered (e.g., attached or bonded) to another layer after bending, and a portion of the conductive layer (342) formed to surround the adhesive substrate layer (341) is exposed to the outside and can come into contact with the second contact element (262).
[0144] According to one embodiment, when a voltage is applied through the circuit board (240) to cause the second contact element (262) to have a positive (+) polarity, the conductive layer (342) electrically connected to the second contact element (262) may form a layer having a positive (+) polarity.
[0145] According to one embodiment, one end of the first extension portion (330b) of the conductive structure (330) may be arranged to face the first contact element (261) arranged on the circuit board (240). When voltage is applied through the circuit board (240), the conductive structure (330) and the first contact element (261) may be formed in a state where they are substantially in contact, for electrical connection between the conductive structure (330) and the first contact element (261).
[0146] According to one embodiment, the first extension portion (330b) of the conductive structure (330) extends inwardly of the circuit board (240) with one side (e.g., a surface) attached to the protective cover (320), and the other side (e.g., a surface) is exposed to the outside and can contact (e.g., be attached to) the first contact element (261).
[0147] According to one embodiment, when a voltage is applied through the circuit board (240) to the first contact element (261) so that it has a negative (-) polarity, the conductive structure (330) electrically connected to the first contact element (261) can form a layer having a negative (-) polarity.

[0149] FIG. 13 is a drawing showing a state in which voltage is applied to a cross-sectional view of the electronic device of FIG. 11 according to one embodiment of the present disclosure.
[0150] FIG. 14 is a diagram illustrating the separation of electric charges related to electrical peeling after voltage is applied to an adhesive structure according to one embodiment of the present disclosure. FIG. 14 is an enlarged cross-sectional view of the first region (S1) of FIG. 12.
[0151] FIG. 15 is a drawing showing a configuration related to electric peeling of FIG. 14 according to one embodiment of the present disclosure.
[0152] The components of the electronic device (101) of FIGS. 12 to 15 may be partially or entirely identical to the components of the electronic device (101) of FIGS. 1 to 11.
[0153] The embodiments of FIGS. 12 to 15 can be optionally combined with the embodiments of FIGS. 1 to 11 and the embodiments of FIGS. 16 to 24.
[0154] According to one embodiment, the electronic device (101) may include at least one of a housing (201), a protective cover (320), a circuit board (240), a battery (250), a conductive structure (330), and / or a conductive adhesive sheet (340).
[0155] According to one embodiment, the adhesive structure can bond the housing (310) and the protective cover (320) with strong adhesive force. The adhesive structure can place a conductive adhesive sheet (340) containing an adhesive component between the housing (310) and the protective cover (320).
[0156] According to one embodiment, the adhesive structure can separate the protective cover (320) from the housing (310) due to the application of voltage. To weaken the adhesive force between the housing (310) and the protective cover, the adhesive structure can provide a structure in which a conductive adhesive sheet (340) having electric peeling properties and a conductive structure (330) forming a charge movement path are laminated.
[0157] According to one embodiment (see FIG. 12), a first extension portion (330b) of the conductive structure (330) may extend inwardly (e.g., in the X-axis direction) of the circuit board (240) and be electrically connected to a first contact element (261) mounted on the circuit board (240). A front side (e.g., a surface) (e.g., a surface facing the +Z-axis) of the conductive structure (330) provides one side (e.g., a surface) exposed toward the circuit board (240), and a portion of the conductive structure (330) may be in physical contact with the first contact element (261). According to one embodiment, when a voltage is applied to the circuit board (240), a current may flow along the electrically connected conductive structure (330). For example, when voltage is applied so that the first contact element (261) has a (-) polarity, the conductive structure (330) electrically connected to the first contact element (261) can form a layer having a (-) polarity.
[0158] According to one embodiment (see FIG. 13), the second extension portion (340b) of the conductive adhesive sheet (340) may extend inwardly (e.g., in the X-axis direction) of the circuit board (240) and be electrically connected to a second contact element (262) mounted on the circuit board (240). The conductive layer (342) of the conductive adhesive sheet (340) may be bent to provide an exposed state toward the circuit board (240), and a portion of the conductive layer (342) may be in physical contact with the second contact element (262). According to one embodiment, when voltage is applied to the circuit board (240), current may flow along the electrically connected conductive layer (342). For example, when voltage is applied so that the second contact element (262) has a (+) polarity, the conductive layer (342) electrically connected to the second contact element (262) may form a layer having a (+) polarity.
[0159] Referring to FIGS. 12 and 13, the conductive structure (330) is formed to have a (-) pole, and the conductive layer (342) of the conductive adhesive sheet (340) is formed to have a (+) pole, but this is not limited thereto, and the design can be changed in various ways depending on the voltage conditions so that the conductive structure (330) is formed to have a (+) pole, and the conductive layer (342) of the conductive adhesive sheet (340) is formed to have a (-) pole.
[0160] According to one embodiment (see FIG. 14), a voltage is applied to the circuit board (240), the conductive structure (330) may be formed so that the edge facing the electrolyte layer (343) has a (+) polarity, and the conductive layer (342) of the conductive adhesive sheet (340) may be formed so that the edge facing the electrolyte layer (343) has a (-) polarity. Thereafter, the (-) charges and (+) charges mixed within the electrolyte layer (343) of the conductive adhesive sheet (340) may move to a region having an opposite polarity. For example, after a certain period of time (e.g., approximately 1 min to 3 min), the (-) charges (second charges) of the electrolyte layer (343) may move toward the conductive structure (330) formed to have a (+) pole, and the (+) charges (first charges) of the electrolyte layer (343) may move toward the conductive layer (342) formed to have a (-) pole. As the (-) charges are arranged near the front side (e.g., the side) (e.g., the side facing the +Z axis) of the electrolyte layer (343) and the (+) charges are arranged near the back side (e.g., the side) (e.g., the side facing the -Z axis) of the electrolyte layer (343), the physical structure of the electrolyte layer (343) may be destroyed and the adhesive strength of the electrolyte layer (343) may be reduced. Thereafter, the decrease in adhesive strength that occurs between the conductive structure (330) and the conductive adhesive sheet (340) allows the protective cover (320) to be easily separated from the housing (310) by a tool such as an adsorber or by a worker (e.g., a user). Hereinafter, the electric peeling characteristics of the conductive adhesive sheet (340) that provides the decrease in adhesive strength will be described in detail.
[0161] According to one embodiment (see FIG. 15), the electrical separation mechanism of the adhesive structure may be a method of electrically weakening the adhesive force by utilizing an ionic liquid within the conductive adhesive sheet (340) to separate the housing (310) and the protective cover (320). The electrical separation mechanism may include dissociation and diffusion of ions, and a chemical reaction at the electrode resulting therefrom.
[0162] According to one embodiment, the electrolyte layer (343) of the conductive adhesive sheet (340) may include a mixture of an acrylic adhesive and an ionic liquid. The ionic liquid may not form crystals and may exist in a liquid state due to the size asymmetry of cations and anions. Unlike conventional salts, the ionic liquid may exist in a liquid state at a temperature of approximately 100°C or lower.
[0163] In one embodiment, in order for the conductive adhesive sheet (340) to provide electrical peeling properties, the arrangement of conductive materials adjacent to the electrolyte layer (343) may be required so that separated charges (e.g., positive charges and negative charges) within the electrolyte layer (343) can easily (e.g., freely) move. For example, a conductive layer (342) and a conductive structure (330) having conductivity may be arranged in contact with the front side (e.g., the surface) and the back side (e.g., the surface) of the electrolyte layer (343) of the conductive adhesive sheet (340), respectively.
[0164] When explaining the electro-peeling process of the conductive adhesive sheet (340), when voltage is applied to the circuit board (240), a (+) voltage is applied to the conductive layer (342) disposed on both sides (e.g., the surface) of the electrolyte layer (343) (e.g., forming a layer having a (+) polarity), and a (-) voltage is applied to the conductive structure (330) (e.g., forming a layer having a (-) polarity), and dissociation and diffusion may occur in the ionic liquid of the electrolyte layer (343). For example, the ionic liquid of the electrolyte layer (343) is composed of (+) ions and (-) ions, and when voltage is applied, the ionic liquid may dissociate into cations and anions. Thereafter, the dissociated ions (e.g., (-) charges and (+) charges) may move under the influence of an electric field. Negative ions (e.g., negative charges) can diffuse toward the positive electrode, and positive ions (e.g., positive charges) can diffuse toward the negative electrode.
[0165] Afterwards, a (-) pole peeling mechanism and / or a (+) pole peeling mechanism may occur. The (-) pole and / or the (+) pole peeling mechanism may be determined to be predominantly one of them depending on the chemical properties of the adhesive, the adherend, and the peeling occurrence conditions. According to one embodiment of the present disclosure, the (-) pole peeling mechanism is predominantly occurred, and thus, separation of the protective cover (320) from the housing (310) may occur.
[0166] In one embodiment, when explaining the (-) pole peeling mechanism, a reduction reaction of (+) ions may occur due to contact between a conductive structure (330) having a (-) pole and (+) ions in the ionic liquid of the electrolyte layer (343). The (+) ions in the electrolyte layer (343) gathered toward the (-) pole of the conductive structure (330) may obtain electrons from the (-) pole and be reduced, thereby causing a chemical reaction that reduces adhesive strength (e.g., adhesive function within the electrolyte layer (343)). For example, the reduced (+) ions may attack the carbonyl group (C=O) forming the backbone structure of the acrylic pressure-sensitive adhesive, and the attack may cause the structure of the adhesive to be deformed or decomposed. The chemical reaction generates hydrogen gas as a byproduct, and the generation of the hydrogen gas may make the structure of the adhesive more unstable. Accordingly, the adhesive strength of the acrylic adhesive at the (-) pole interface is reduced due to the above chemical reactions, and the weakened adhesive strength can facilitate separation between the conductive structure (330) and the conductive adhesive sheet (340).
[0167] According to one embodiment, when explaining the (+) pole peeling mechanism, an oxidation reaction of the (+) pole may occur due to contact of (-) ions in the ionic liquid of the conductive layer (342) having a (+) pole and the electrolyte layer (343). The (-) ions in the electrolyte layer (343) gathered toward the (+) pole of the conductive layer (342) cause an oxidation reaction at the (+) pole, and in the reaction, the metal (e.g., the conductive layer (342)) used in the (+) pole may be oxidized. Thereafter, as a result of the oxidation reaction, an oxide layer is generated at the (+) pole interface, and the oxide film layer may be formed on the surface of the metal (e.g., the conductive layer (342)) to weaken the bonding force between the adhesive and the metal (e.g., the conductive layer (342)). Accordingly, the adhesive strength of the acrylic adhesive on one side (e.g., surface) of the metal (e.g., conductive layer (342)) is reduced by the formation of the oxide layer, and the weakened adhesive strength can facilitate separation between the conductive layer (342) and the electrolyte layer (343) within the conductive adhesive sheet (340).
[0168] FIG. 16 is a flowchart illustrating a separation operation between a housing and a protective cover of an electronic device according to one embodiment of the present disclosure.
[0169] FIG. 17 is a flowchart illustrating a separation operation between a housing and a protective cover of an electronic device according to one embodiment of the present disclosure. The configuration of the electronic device (101) of FIGS. 16 and 17 may be partially or entirely identical to the configuration of the electronic device (101) of FIGS. 1 to 15.
[0170] The embodiments of FIGS. 16 and 17 can be optionally combined with the embodiments of FIGS. 1 to 15 and the embodiments of FIGS. 18 to 24.
[0171] According to one embodiment, the electronic device (101 of FIGS. 1 to 14) may include at least one of a housing (310 of FIGS. 7 to 14), a protective cover (320 of FIGS. 7 to 14), a circuit board (240 of FIGS. 7 to 14), a battery (250 of FIGS. 7 to 14), a conductive structure (330 of FIGS. 7 to 14), and / or a conductive adhesive sheet (340 of FIGS. 7 to 14).
[0172] Fig. 16 shows a flow chart for supplying voltage from a battery (250) in an electronic device (101) and separating a protective cover (320).
[0173] First, when a user wishes to disassemble the electronic device (101) (e.g., separate the protective cover (320) from the housing (310), the user's intention can be transmitted (e.g., identified or determined) to the electronic device (101) (e.g., processor (120) of FIG. 1). In operation 1010, the user can enter (e.g., input) a setting mode within the electronic device (101) and perform a mode progression for separating the protective cover (320) from the housing (310). The setting mode can be entered, for example, through an application and / or a button.
[0174] In operation 1020, the processor (120) of the electronic device (101) may determine whether the user has selected to separate the protective cover (320) in order to proceed with the separation mode. If the processor (120) determines that the separation mode is to be performed by receiving a separation mode input value within the setting mode of the electronic device (101), the processor may proceed to a subsequent operation (e.g., operation 1030). If the processor (120) does not receive a separation mode input value within the setting mode of the electronic device (101) (or receives a non-separation mode input value) and determines that the separation mode is not to be performed, the processor may return to operation 1020.
[0175] In operation 1030, the processor (120) of the electronic device (101) can activate an electrical connection between the conductive adhesive sheet (340) (and / or the conductive structure (330)) and the circuit board (240). For example, the processor (120) can activate the electrical connection by turning on a switch connected to a second contact element (262) disposed on the circuit board (240) connected to the conductive layer (342) of the conductive adhesive sheet (340), and a first contact element (261) disposed on the circuit board (240) connected to the conductive structure (330), respectively.
[0176] In operation 1040, the process (120) of the electronic device (101) can apply a voltage from a low dropout regulator (LDO) to the conductive adhesive sheet (340) (and / or the conductive structure (330)) through the circuit board (240). For example, the LDO connected to the battery (250) can convert the voltage of the battery (250) into a stable output voltage to enable the circuit of the circuit board (240) to operate stably. When a voltage (e.g., 9 V) is applied to the circuit board (240) through the LDO connected to the battery (250), the first contact element (261) can cause the conductive structure (330) to have a (-) polarity through the first extension portion (330b) of the conductive structure (330). When voltage is applied to the circuit board (240) through the LDO connected to the battery (250), the second contact element (262) can cause the conductive layer (342) to have a positive (+) polarity through the second extension portion (340b) of the conductive adhesive sheet (340).
[0177] In operation 1050, if a certain period of time passes while the voltage is applied, the (-) charges and (+) charges mixed within the electrolyte layer (343) may move to regions having opposite polarities. For example, between approximately 1 min and 2 min, the (-) charges of the electrolyte layer (343) may move toward the conductive structure (330) forming the (+) pole, and the (+) charges of the electrolyte layer (343) may move toward the conductive layer (342) of the conductive adhesive sheet (340) forming the (-) pole. The movement of each charge may reduce the adhesive force of the electrolyte layer (343).
[0178] The process (120) of the electronic device (101) may proceed to a subsequent operation (e.g., operation 1060) when a preset period of time (e.g., 4 min) has elapsed while the voltage is applied. The process (120) may maintain operation 1050 until a preset period of time has elapsed while the voltage is applied.
[0179] In operation 1060, the processor (120) of the electronic device (101) determines whether the protective cover (320) is detachable from the housing (310), and based on the determination, may notify the user of whether the protective cover (320) is detachable. For example, the processor (120) may determine the degree of adhesion reduction between the conductive adhesive sheet (340) and the conductive structure (330), and notify the user of whether the protective cover is detachable. For example, after voltage is applied to the circuit board (240), after a preset time (e.g., a designated time) (e.g., 4 minutes or more) has elapsed, the processor (120) may notify the user of whether the protective cover (320) is detachable. The method of notifying the user of whether the protective cover is detachable may be transmitted (e.g., provided) in various ways that the user can confirm. For example, the information may be transmitted as text on the display of the electronic device (or wearable electronic device) or as a voice-like message.
[0180] In operation 1070, the user (or operator) can directly separate the protective cover (320) from the housing (310) after receiving a notification from the electronic device (101) that the protective cover (320) is in a detachable state. The separation of the protective cover (320) can be performed by pulling the protective cover (320) with a hand or by pulling the protective cover (320) using an absorber, depending on the degree to which the adhesive force between the housing (310) and the protective cover (320) is reduced.
[0181] In operation 1080, the processor (120) of the electronic device (101) may proceed with the next process or maintain the current process depending on whether a predetermined period of time has elapsed after the protective cover (320) is detached. For example, if a preset period of time (e.g., 20 minutes) has elapsed after the protective cover (320) is detached, operation 1090 may be performed. Operation 1080 may be maintained until a preset period of time has elapsed while the voltage is applied.
[0182] In operation 1090, if the processor (120) of the electronic device (101) determines that the preset period of time (e.g., 20 min) of operation 1080 has elapsed, the processor (120) may deactivate the electrical connection between the conductive adhesive sheet (340) (and / or the conductive structure (330)) and the circuit board (240). For example, the processor (120) may activate the electrical connection by turning off a switch connected to a second contact element (262) disposed on the circuit board (240) connected to the conductive layer (342) of the conductive adhesive sheet (340), and a first contact element (261) disposed on the circuit board (240) connected to the conductive structure (330), respectively.
[0183] Fig. 17 illustrates a flowchart of separating a protective cover (320) by supplying voltage from an external power source to an electronic device (101). The flowchart of Fig. 17 may apply the configuration of operations 1020 to 1090 of the flowchart of Fig. 16. Hereinafter, operations prior to operation 1020, which are different from the flowchart of Fig. 16, will be described.
[0184] Referring to FIG. 17, when a user wants to disassemble the electronic device (101) (e.g., separate the protective cover (320) from the housing (310), the user's intention (e.g., user input) can be transmitted (e.g., identified or determined) to the electronic device (101) (e.g., processor (120) of FIG. 1). In operation 1011, if the user enters the setting mode within the electronic device (101), and performs the mode progression of separating the protective cover (320) from the housing (310), the processor (120) of the electronic device (101) can guide the connection of the electronic device (101) and a terminal adapter (TA) (e.g., an external power cable). The setting mode can be entered, for example, through an application and / or a button. The guiding method can be transmitted (e.g., provided) to the user in the form of a message through the screen of the electronic device (101).
[0185] In operation 1015, the processor (120) of the electronic device (101) may check whether there is an electrical connection between the electronic device (101) and a terminal adapter (TA) and perform subsequent operations. If the processor (120) determines that an external power source is connected to the electronic device (101), the process may proceed to operation 1020. If the processor (1020) determines that an external power source is not connected to the electronic device (101), the process may return to operation 1011.
[0186] Thereafter, operations 1020 to 1090 may apply the contents disclosed above (e.g., processes or determinations).

[0194] According to one embodiment, in the second extended portion (340b) of the conductive adhesive sheet (340), the conductive layer (342) may be exposed toward the protective cover (320) while being disposed on the adhesive substrate layer (341). For electrical connection between the conductive layer (342) and the second contact element (262) disposed on the circuit board (240), a plurality of conductive materials may be positioned between the conductive layer (342) and the second contact element (262).

[0195] According to one embodiment, the plurality of conductive materials may include a first conductive adhesive portion (501) and a second conductive adhesive portion (502). The first conductive adhesive portion (501) may be a conductive double-sided tape having a double-sided adhesive property. The first conductive adhesive portion (501) may have one side (e.g., a side facing the -Z axis) adhered to the protective cover (320), and the other side (e.g., a side) (e.g., a side facing the +Z axis) adhered to the conductive layer (342) and the second conductive adhesive portion (502). The second conductive adhesive portion (502) may be a conductive single-sided tape having one side (e.g., a side) having an adhesive property. The second conductive adhesive portion (502) may have one side (e.g., a surface) (e.g., a surface facing the -Z axis) adhered to the first conductive adhesive portion (501), and the other side (e.g., a surface) (e.g., a surface facing the +Z axis) may be in contact with the second contact element (262).
[0196] According to one embodiment, the conductive layer (342) of the conductive adhesive sheet (340) may have one side connected to the electrolyte layer (343) and the other side connected to the first conductive adhesive portion (501). One side of the first conductive adhesive portion (501) may be located on one side (e.g., a surface) (e.g., a surface facing the -Z axis) of the conductive layer (342). According to one embodiment, the first conductive adhesive portion (501) disposed on the protective cover (320) and extending inwardly of the circuit board (240) may be disposed such that the overlapping region of the second contact element (262) is laminated with the second conductive adhesive portion (502).

[0197] According to one embodiment, the adhesive substrate layer (341), the conductive layer (342), the first conductive adhesive portion (501), and the second conductive adhesive portion (502) may have a plate shape (e.g., a rigid or straight shape), which may be different from the structure of the bent adhesive substrate layer (341) and the conductive layer (342) of FIG. 10. The thickness of a portion of the conductive adhesive sheet (340) (the adhesive substrate layer (341), the conductive layer (342)) arranged parallel to one side (e.g., the surface) of the first conductive adhesive portion (501) and the second conductive adhesive portion (502) may be substantially the same. The thickness of the first conductive adhesive portion (501) may be substantially the same as the sum of the thicknesses of the conductive layer (342) and the electrolyte layer (343).
[0198] According to one embodiment, when voltage is applied to the circuit board (240), the current transmitted to the second contact element (262) may be transmitted to the conductive layer (342) via the second conductive adhesive portion (502) and the first conductive adhesive portion (501). For example, the conductive layer (342) may have a positive (+) pole.

[0202] The embodiments of FIGS. 19 and 20 can be optionally combined with the embodiments of FIGS. 1 to 18 and the embodiments of FIGS. 21 to 24.
[0203] According to one embodiment, the electronic device (101) may include at least one of a housing (310), a protective cover (320), a circuit board (240), a conductive structure (330), and / or a conductive adhesive sheet (340).

[0206] According to one embodiment, the adhesive structure may be a structure in which a conductive structure (330), a conductive adhesive sheet (340), and a protective cover (320) are sequentially laminated on a second side wall portion (312b) of a housing (310). The first side wall portion (312a) of the housing (310) may be formed to surround the outer side (e.g., surface) of the conductive structure (330), the conductive adhesive sheet (340), and the protective cover (320).
[0207] Referring to FIG. 19, a conductive structure (330) may be placed between a conductive adhesive sheet (340) and a housing (310). In a first extension portion (330b) of the conductive structure (330), the conductive structure (330) may be placed on the housing (310).
[0208] According to one embodiment, the conductive structure (330) may be arranged in a curved shape along the second side wall portion (312b) of the housing (310) toward the support plate (311). A portion of the conductive structure (330) may be arranged adjacent to the circuit board (240).

[0209] In one embodiment, the conductive structure (330) extending into the circuit board (240) may be coupled to one side (e.g., surface) of the housing (310) and may have a structure different from that of the conductive structure (330) extending into the circuit board (240) of FIG. 10. In one embodiment, when voltage is applied to the circuit board (240), the current transmitted to the first contact element (261) may form a path along the conductive structure (330). For example, the conductive structure (330) may have a (-) polarity.
[0210] Referring to FIG. 20, a conductive adhesive sheet (340) adhered (e.g., attached) to a protective cover (320) may include an adhesive substrate layer (341), a conductive layer (342), and an electrolyte layer (343) laminated in the +Z-axis direction. Among the conductive adhesive sheets (340), the adhesive substrate layer (341) and the conductive layer (342) may each include an extended portion (e.g., a second extended portion (340b)) protruding toward the circuit board (240) to be connected to the contact element (260).

[0212] According to one embodiment, the adhesive substrate layer (341) and the conductive layer (342) extending inwardly of the circuit board (240) may have a plate shape (e.g., a rigid or straight shape), which may be different from the structure of the bent adhesive substrate layer (341) and the conductive layer (342) of FIG. 11. According to one embodiment, when voltage is applied to the circuit board (240), the current transmitted to the second contact element (262) may form a path along the conductive layer (342).

[0214] FIG. 22 is a cross-sectional view taken along line B-B' of a portion of the electronic device of FIG. 8 according to one embodiment of the present disclosure.
[0215] The configuration of the electronic device (101) of FIGS. 21 and 22 may be partially or entirely identical to the configuration of the electronic device (101) of FIGS. 1 to 17.
[0216] The embodiments of FIGS. 21 and 22 can be optionally combined with the embodiments of FIGS. 1 to 20 and the embodiments of FIGS. 23 to 24.
[0217] According to one embodiment, the electronic device (101) may include at least one of a housing (310), a protective cover (320), a circuit board (240), a conductive structure (330), and / or a conductive adhesive sheet (340).
[0218] Fig. 21 shows the electrical connection relationship between the second conductive layer (342b) of the conductive adhesive sheet (340) and the first contact element (261), and Fig. 22 shows the electrical connection relationship between the first conductive layer (342a) of the conductive adhesive sheet (340) and the second contact element (262).
[0219] Referring to FIGS. 21 and 22, a conductive adhesive sheet (340) can be placed between the housing (310) and the protective cover (320) to combine the housing (310) and the protective cover (320).
[0220] According to one embodiment, the adhesive structure may be a structure in which a conductive adhesive sheet (340) and a protective cover (320) are sequentially laminated on a second side wall portion (312b) of a housing (310). The conductive adhesive sheet (340) may include a plurality of conductive layers, and each conductive layer may be arranged toward the housing (310) side and the protective cover (320) side.
[0221] According to one embodiment, the conductive adhesive sheet (340) may include an adhesive substrate layer (341), a first conductive layer (342a), an electrolyte layer (343), and a second conductive layer (342b). The adhesive substrate layer (341), the conductive layer (342), the electrolyte layer (343), and the second conductive layer (342b) may have a closed loop shape that corresponds to each other as a whole. The adhesive substrate layer (341), the conductive layer (342), the electrolyte layer (343), and / or the second conductive layer (342b) may each include an extended portion extending toward the circuit board (240) (e.g., in the X-axis direction) to be connected to the contact elements (261, 262).
[0222] According to one embodiment, the adhesive substrate layer (341) of the conductive adhesive sheet (340) may be disposed between the housing (310) (e.g., the second side wall portion (312b)) and the first conductive layer (342a). The adhesive substrate layer (341) may provide a support layer function for supporting the conductive adhesive sheet (340) as a whole.
[0223] According to one embodiment, the first conductive layer (342a) of the conductive adhesive sheet (340) may be disposed between the adhesive substrate layer (341) and the electrolyte layer (343). The first conductive layer (342a) is a layer for the movement of charges constituting the electrolyte layer (343) and may provide a current-conducting function like a metal. For example, if voltage is applied to the conductive adhesive sheet (340), the first conductive layer (342a) may assume one of the (-) pole or the (+) pole (e.g., the (+) pole in FIG. 22), and some of the charges of the electrolyte layer (343) may move toward the first conductive layer (342a).
[0224] According to one embodiment, the electrolyte layer (343) of the conductive adhesive sheet (340) may be disposed between the first conductive layer (342a) and the second conductive layer (342b). According to one embodiment, the electrolyte layer (343) may include an electrolyte to provide an electric peeling property, and an adhesive function for adhering the conductive adhesive sheet (340) to the first conductive layer (342a) and the second conductive layer (342b) (or the protective cover (320)), for example, the function of a pressure-sensitive adhesive.
[0225] According to one embodiment, the electrolyte layer (343) includes a material that is dissolved in a solvent and dissociates into ions to have electrical conductivity, and may be in a state in which (+) charges and (-) charges are mixed and distributed. The electrolyte layer (343) may be in a solid electrolyte or gel electrolyte state. When voltage is applied to the conductive adhesive sheet (340) to separate the housing (310) and the protective cover (320), the electrolyte layer (343) can separate the (+) charges and (-) charges, thereby allowing the electrolyte layer (343) and the second conductive layer (342b) (or the first conductive layer (342a)) to be easily separated.
[0226] According to one embodiment, the second conductive layer (342b) of the conductive adhesive sheet (340) may be disposed between the electrolyte layer (343) and the protective cover (320). The second conductive layer (342b) is a layer for the movement of charges constituting the electrolyte layer (343) and may provide a conducting function like a metal. For example, if voltage is applied to the conductive adhesive sheet (340), the second conductive layer (342b) may assume one of the (-) pole or the (+) pole (e.g., the (-) pole in FIG. 21), and some of the charges of the electrolyte layer (343) may move toward the second conductive layer (342b).
[0227] Referring to FIG. 21, in the extended portion of the conductive adhesive sheet (340), the length (X-axis direction) of the second conductive layer (342b) may have a longer (e.g., larger) length than the lengths of other layers of the conductive adhesive sheet (340). The conductive adhesive sheet (340) may be laminated in the -Z-axis direction with respect to the adhesive base layer (341) disposed on the housing (310) as a first conductive layer (342a), an electrolyte layer (343), and a second conductive layer (342b). In order for the second conductive layer (342b) disposed between the electrolyte layer (343) and the protective cover (320) to come into contact with the first contact element (261), it is necessary to expose a portion covered by the electrolyte layer (343) to the outside, and the length of the second conductive layer (342b) is designed to be longer (e.g., larger) than the lengths of the first conductive layer (342a) and the electrolyte layer (343), so that a portion of the second conductive layer (342b) can come into contact with the first contact element (261).
[0228] According to one embodiment, in the extended portion of the conductive adhesive sheet (340), the second conductive layer (342b) is bonded to the protective cover (320) via the adhesive material (371), and the adhesive substrate layer (341), the first conductive layer (342a), the electrolyte layer (343), and the second conductive layer (342b) extended to the circuit board (240) can form a bent section. In the bent section, the second conductive layer (342b) forms an outermost layer while wrapping the adhesive substrate layer (341), the first conductive layer (342a), and the electrolyte layer (343), and is exposed to the outside and can come into contact with the first contact element (261).
[0229] Referring to FIG. 21, in the extended portion of the conductive adhesive sheet (340), the length (X-axis direction) of the first conductive layer (342a) may have a length longer (e.g., greater) than the length of the adhesive substrate layer (341) of the conductive adhesive sheet (340). The conductive adhesive sheet (340) may be laminated in the -Z-axis direction with respect to the adhesive substrate layer (341) as a first conductive layer (342a), an electrolyte layer (343), and a second conductive layer (342b). In order for the first conductive layer (342a) disposed between the conductive adhesive sheet (340) and the electrolyte layer (343) to contact the second contact element (262), it is necessary to expose the portion covered by the conductive adhesive sheet (340) to the outside, and the exposed first conductive layer (342a) may contact the second contact element (262).
[0230] FIG. 23 is a cross-sectional view taken along line A-A' of a portion of the electronic device of FIG. 8 according to one embodiment of the present disclosure.
[0231] FIG. 24 is a cross-sectional view taken along line B-B' of a portion of the electronic device of FIG. 8 according to one embodiment of the present disclosure.
[0232] The configuration of the electronic device (101) of FIGS. 23 and 24 may be partially or entirely identical to the configuration of the electronic device (101) of FIGS. 1 to 17.
[0233] The embodiments of FIGS. 23 and 24 can be optionally combined with the embodiments of FIGS. 1 to 20 and the embodiments of FIGS. 23 to 24.
[0234] According to one embodiment, the electronic device (101) may include at least one of a housing (310), a protective cover (320), a circuit board (240), a conductive structure (337, 338), and / or an electrolyte sheet (380).
[0235] Fig. 23 illustrates an electrical connection relationship between a first conductive structure (337) and a second contact element (262), and Fig. 24 illustrates an electrical connection relationship between a second conductive structure (338) and a first contact element (261). Referring to Figs. 23 and 24, the first and second conductive structures (337, 338) may be positioned between a housing (310) and a protective cover (320).
[0236] According to one embodiment, the adhesive structure may be a structure in which a first conductive structure (337), an electrolyte sheet (380), and a second conductive structure (338) are sequentially laminated on a second side wall portion (312b) of the housing (310). The adhesive structure may include a plurality of conductive structures on both sides of the electrolyte sheet (380), and each conductive structure may be arranged toward the housing (310) side and the protective cover (320) side.
[0237] According to one embodiment, the first conductive structure (337), the electrolyte sheet (380), and the second conductive structure (338) may have a closed loop shape that corresponds to each other as a whole. The first and second conductive structures (337, 338) may include extended portions that protrude toward the circuit board (240) to be connected to the contact elements (261, 262).
[0238] According to one embodiment, the first conductive structure (337) and the second conductive structure (338) may be respectively disposed on the upper and lower sides (e.g., the surface) of the electrolyte sheet (380). The first conductive structure (337) and the second conductive structure (338) may serve as layers for the movement of charges constituting the electrolyte sheet (380) and may provide a conductive function, such as a metal. For example, if voltage is applied to the first conductive structure (337) and the second conductive structure (338), the first conductive structure (337) may assume one of the (-) pole or the (+) pole (e.g., the (-) pole in FIG. 23), and some of the charges of the electrolyte sheet (380) may move toward the first conductive structure (337). The second conductive structure (338) has either a (+) pole or a (-) pole (e.g., a (+) pole in FIG. 24), and some of the charges of the electrolyte sheet (380) can move toward the second conductive structure (338).
[0239] According to one embodiment, the electrolyte sheet (380) includes a material that is dissolved in a solvent and dissociates into ions to have electrical conductivity, and may have (+) charges and (-) charges mixed and distributed. When voltage is applied to the first conductive structure (337) and the second conductive structure (338) to separate the housing (310) and the protective cover (320), the electrolyte sheet (380) can separate the (+) charges and (-) charges, thereby allowing the electrolyte layer (343) and the first conductive structure (337) (or the second conductive structure (338)) to be easily separated.
[0240] Referring to FIG. 23, the first conductive structure (337) may be positioned between the electrolyte sheet (380) and the housing (310). In an extended portion of the first conductive structure (337) (e.g., a portion extending toward the circuit board (240), the first conductive structure (337) may be positioned to correspond to the curved shape of the housing (310).
[0241] According to one embodiment, the first conductive structure (337) may be arranged in a curved shape along the second side wall portion (312b) of the housing (310) toward the support plate (311). A portion of the first conductive structure (337) may be arranged adjacent to the circuit board (240). The first conductive structure (337) may be exposed toward the circuit board (240) while being coupled to the housing (310). The first conductive structure (337) may be electrically connected to the first contact element (261) arranged on the circuit board (240).
[0242] In one embodiment, when voltage is applied to the circuit board (240), the current transmitted to the first contact element (261) may form a path along the first conductive structure (337). For example, the first conductive structure (337) may have a negative (-) polarity.
[0243] Referring to FIG. 24, in an extended portion of the second conductive structure (338) (e.g., a portion extending toward the circuit board (240), the length (X-axis direction) of the second conductive structure (338) may have a length longer (e.g., greater) than the lengths of the electrolyte sheet (380) and the first conductive structure (337). The adhesive structure may laminate the electrolyte layer (343) and the second conductive structure (338) in the -Z-axis direction based on the first conductive structure (337) disposed on the housing (310). In order for the second conductive structure (338) to contact the second contact element (262), it is necessary to expose the portion surrounded by the electrolyte layer (343) and the first conductive structure (337) to the outside, and the exposed second conductive structure (338) may contact the second contact element (262).
[0244] In one embodiment, when voltage is applied to the circuit board (240), the current transmitted to the second contact element (262) may form a path along the second conductive structure (338). For example, the second conductive structure (338) may have a positive (+) pole.
