[0032] Figure 1 An electronic device according to an embodiment of the present disclosure is shown.

[0033] Reference Figure 1 , the electronic device 101 may include a display 110 and a housing (or body) 120 .

[0034] The display 110 according to various embodiments may include, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a micro-electromechanical system (MEMS) display, or electronic paper. For example, the display 110 may display various types of content (e.g., text, images, videos, icons, and / or symbols) to the user. The display 110 may include a touch screen, and may receive, for example, touch, gesture, proximity, or hover input using an electronic pen or a part of the user's body.

[0035] The housing (or body) 120 according to various embodiments may have the display 110 installed therein. The housing 120 may contain various components for driving the electronic device 101.

[0036] According to various embodiments, the housing 120 may include a main circuit board 130 , a battery 140 , a battery protection module 150 , and a flexible printed circuit board 180 .

[0037] The main circuit board 130 according to various embodiments may have various elements mounted thereon and required for the operation of the electronic device 101. For example, the main circuit board 130 may have a processor, a memory, a communication chip, or a sensor mounted thereon. The main circuit board 130 may include a power supply point. The power supply point may be a point to which the power of the battery 140 is supplied through the flexible printed circuit board 180. The main circuit board 130 may supply the power transmitted through the power supply point to the mounted or connected elements.

[0038] The battery 140 according to various embodiments may store electrical energy according to chemical properties. The battery 140 may supply power to the main circuit board 130 through the battery protection module 150 and the flexible printed circuit board 180. For example, the battery 140 may be implemented in a Li-ion type.

[0039] The battery protection module 150 according to various embodiments may prevent overcharge or overdischarge of the battery 140 and may protect the battery 140 from overcurrent. For example, the battery protection module 150 may be a protection circuit module (PCM) or a protection circuit board (PCB). According to various embodiments, the battery protection module 150 may be surrounded by a protection bracket (or battery bracket) (e.g., a PCM bracket).

[0040] The flexible printed circuit board 180 may be connected between the battery protection module 150 and the main circuit board 130. The flexible printed circuit board 180 may transmit power from the battery 140 to a power supply point of the main circuit board 130. A first end portion of the flexible printed circuit board 180 may be connected to the battery protection module 150. A second end portion of the flexible printed circuit board 180 may be connected to a power supply point of the main circuit board 130.

[0041] According to various embodiments, at least a portion of the flexible printed circuit board 180 may be bent in a "U" shape. For example, the flexible printed circuit board 180 may be bent into a "U" shape after extending a predetermined length from the first end portion in a lateral outward direction of the electronic device 101 (a direction perpendicular to a direction in which the battery protection module 150 faces the main circuit board 130). After being bent into the "U" shape, the flexible printed circuit board 180 may be disposed to overlap the battery protection module 150 (see Figures 3 to 6 ).

[0042] Figure 2 Components around a battery are shown according to an embodiment of the present disclosure.

[0043] Reference Figure 2 , the battery 140 can store electrical energy according to chemical properties. For example, the battery (or battery structure) 140 may include a positive electrode plate, a negative electrode plate, a separator, a jelly roll, and a bag (or battery bag). The positive electrode plate and the negative electrode plate may be separated from each other by a separator. The positive electrode plate, the negative electrode plate, and the separator may form a jelly roll, and the jelly roll may be sealed with a bag (e.g., polypropylene (PP) + nylon + aluminum).

[0044] The battery protection module (or protection module) 150 according to various embodiments may be mounted on one side surface of the battery 140 (a side surface adjacent to the main circuit board 130). The battery protection module 150 may include a substrate, a protection integrated circuit (IC), a first terminal plate 151, and a second terminal plate 152 (see Figure 7a and Figure 7b ). The first tab 151 may be connected to a first electrode (positive electrode plate) (eg, Al) of the battery 140 , and the second tab 152 may be connected to a second electrode (negative electrode plate) (eg, Cu) of the battery 140 .

[0045] According to various embodiments, the battery protection module 150 may be surrounded by a protection bracket (or battery bracket) 155. When the jelly roll in the battery 140 moves in a state where the protection bracket 155 does not exist (for example, when the electronic device 101 is subjected to a drop shock), the battery protection module 150 may be broken, and the jelly roll may penetrate the bag and may be exposed to the outside of the battery 140. On the contrary, when the jelly roll in the battery 140 moves in a state where the protection bracket 155 exists, the protection bracket 155 may support the jelly roll, thereby preventing the bag of the battery 140 from bursting.

[0046] The flexible printed circuit board 180 may be connected to one side surface of the battery protection module 150. The flexible printed circuit board 180 may be connected to the side surface of the battery protection module 150 other than the surface of the battery protection module 150 facing the main circuit board 130 (the surface on which the first and second tabs 151 and 152 are mounted).

[0047] According to one embodiment, in a state 180a not combined with the battery protection module 150, the flexible printed circuit board 180 may have a planar form. When combined with the battery protection module 150, the flexible printed circuit board 180 may be at least partially bent into a "U" shape. The flexible printed circuit board 180 may include a first portion connected to the battery protection module 150, a second portion bent into a "U" shape from the first portion, a third portion extending from the second portion and stacked on the battery protection module 150, a fourth portion extending from the third portion toward the main circuit board 130, and a connector connected to the main circuit board 130 (see Figure 4 ).

[0048] According to various embodiments, a portion of the flexible printed circuit board 180 may be exposed outside the protective bracket 155. The protective bracket 155 may include an opening or a groove in a region adjacent to the flexible printed circuit board 180. The flexible printed circuit board 180 may extend outside the protective bracket 155 through the opening or the groove.

[0049] Figure 3 Attachment of a cover tape according to an embodiment of the present disclosure is shown.

[0050] Reference Figure 3 , the battery protection module 150 and the protection bracket 155 connected to the battery 140 may be covered by the cover tape 310. The cover tape 310 may cover the side surface of the battery 140 to which the battery protection module 150 is connected, a portion of the upper surface of the battery 140 adjacent to the side surface, and a portion of the lower surface of the battery 140 opposite to the upper surface. The cover tape 310 may prevent the movement of the protection bracket 155, thereby maintaining the form of the battery protection module 150 and the protection bracket 155 and the gap therebetween.

[0051] According to an embodiment, the flexible printed circuit board 180 may extend in a direction toward the side surface not covered by the cover tape 310, and a portion of the flexible printed circuit board 180 may be disposed above the cover tape 310. For example, a portion of the flexible printed circuit board 180 extending from the U-shaped portion may be disposed above the cover tape 310 attached to the protective bracket 155.

[0052] Figure 4 A form of a flexible printed circuit board according to an embodiment of the present disclosure is shown.

[0053] Reference Figure 4 , the flexible printed circuit board 180 may include a first portion 410 , a second portion 420 , a third portion 430 , a fourth portion 440 , and a connector 450 .

[0054] The first portion 410 (or the battery protection module connection portion) according to various embodiments may be a portion connected to the battery protection module 150. The first portion 410 may extend from the battery protection module 150 in a direction (hereinafter referred to as a second direction (eg, -x direction)) perpendicular to the direction toward the main circuit board 130 (or the direction in which the first terminal tab 151 and the second terminal tab 152 protrude) (hereinafter referred to as the first direction (eg, -y direction)). The second direction may be a direction from the inside of the electronic device 101 toward the outside. The first portion 410 may be disposed on the same layer (same plane) as the battery protection module 150.

[0055] According to various embodiments, the width of the first portion 410 may be equal to the width of the connection portion (eg, Figure 7a In one embodiment, one side surface of the battery protection module 150 may have a greater width than another portion of the battery protection module 150 (see Figure 7a and Figure 7b ). The resistance of the conductor may decrease as the width of the first portion 410 increases.

[0056] The second portion 420 (or the bent portion) according to various embodiments may be a portion formed to be bent into a "U" shape from the first portion 410 in a direction perpendicular to the first direction and the second direction (e.g., +z direction). The curvature of the second portion 420 may be determined according to material properties. The first portion 410 and the third portion 430 may form different layers through the second portion 420.

[0057] The third portion 430 (or the first extension) according to various embodiments may be a portion extending from the second portion 420 in a third direction (e.g., +x direction) opposite to the second direction. The third portion 430 may be disposed on a different layer (different plane) from the first portion 410 because the second portion 420 is bent into a "U" shape. In addition, the third portion 430 may be disposed on a different layer (different plane) from the battery protection module 150. The third portion 430 may be disposed on the upper portion (outer surface) of the battery protection module 150.

[0058] According to various embodiments, the third portion 430 may have a straight line form. The third portion 430 may extend along the upper surface of the battery protection module 150 (or the upper surface of the protection bracket 155) in parallel with the first portion 410. As the length of the third portion 430 increases, the third portion 430 may better resist stress caused by external impact (see Figure 5 ).

[0059] The fourth portion 440 (or the second extension) according to various embodiments may be a portion extending from the third portion 430 in a first direction (e.g., -y direction) toward the main circuit board 130. The fourth portion 440 may be disposed on the same layer (same plane) as the third portion 430. The fourth portion 440 may be formed into an "L" shape together with the third portion 430. The fourth portion 440 may be implemented in the form of a straight line or a curve. Depending on the position of the power supply point of the main circuit board 130 and the form of the main circuit board 130, the fourth portion 440 may be implemented in various forms.

[0060] The connector 450 according to various embodiments may be disposed on the end portion of the fourth portion 440. The connector 450 may be connected to a different connector of the main circuit board 130 (e.g., a connector paired with the connector 450). According to an embodiment, the flexible printed circuit board 180 may include a pad implemented with a metal material (e.g., Cu) on a surface opposite to the surface on which the connector 450 is disposed. According to various embodiments, the connector 450 may be in various forms. For example, the connector 450 may be implemented in the form of a contact pad. According to another embodiment, the connector 450 may be implemented with a wire connected by welding.

[0061] According to various embodiments, the fourth portion 440 may include a V or W bent portion 441 on at least a portion thereof. The V or W bent portion 441 may improve the buffering function of the fourth portion 440 when the jelly roll in the battery 140 moves (eg, when the electronic device 101 is subjected to a drop shock).

[0062] although Figure 4An example is shown in which the fourth portion 440 includes a V or W bent portion 441 , but the present disclosure is not limited thereto. For example, the flexible printed circuit board 180 may include a V or W bent portion on the first portion 410 or the third portion 430 .

[0063] Figure 5 A deformation form depending on the width and stress of a flexible printed circuit board according to an embodiment of the present disclosure is shown.

[0064] Reference Figure 5 , the flexible printed circuit board 180 may include a first portion 410 , a second portion 420 , a third portion 430 , a fourth portion 440 , and a connector 450 .

[0065] The first portion 410 may be disposed inside the protective bracket 155 , and the third portion 430 , the fourth portion 440 , and the connector 450 may be disposed outside the protective bracket 155 .

[0066] According to various embodiments, the first portion 410, the second portion 420, and the third portion 430 may have a first width A. The first width A may be determined according to a connection portion (eg, Figure 7a The first width A may be smaller than the width of the battery protection module 150.

[0067] The fourth portion 440 may have a second width B greater than the first width A. As the second width B increases, resistance (eg, direct current (DC) resistance) occurring in the fourth portion 440 may decrease. The fourth portion 440 may include a V or W bent portion 441 .

[0068] When the jelly roll in the battery 140 moves (for example, when the electronic device 101 is subjected to a drop shock), the first to fourth portions 410 to 440 may be deformed, and the flexible printed circuit board 180 may be stretched in the up / down direction (Y-axis direction). Therefore, the flexible printed circuit board 180 may be prevented from being separated from the main circuit board 130 or the battery protection module 150.

[0069] When the first to fourth portions 410 to 440 are deformed, the first to fourth portions 410 to 440 may be subjected to stress caused by the deformation. The first portion 410, the second portion 420, and the third portion 430 may be subjected to greater stress than the fourth portion 440. The fourth portion 440 may be subjected to less stress than the first portion 410, the second portion 420, and the third portion 430.

[0070] When the electronic device 101 is subjected to a drop shock, the angle "a" between the third portion 430 and the straight line X' parallel to the X axis may increase. As the length of the third portion 430 increases, the angle "a" capable of coping with the movement of the battery 140 may increase, and an effective response to external shocks may be made.

[0071] When the electronic device 101 is subjected to a drop shock, the fourth portion 440 may be extended by the V or W bent portion 441 of the fourth portion 440. Therefore, an effective response to the external shock may be made.

[0072] Figure 6 A form of a flexible printed circuit board above a protective bracket according to an embodiment of the present disclosure is shown.

[0073] Reference Figure 6 , the flexible printed circuit board 601 (e.g., the flexible printed circuit board 180) may include a first part (not shown) (e.g., the first part 410), a second part 620 (e.g., the second part 420), a third part 630 (e.g., the third part 430), a fourth part 640 (e.g., the fourth part 440) and a connector 650 (e.g., the connector 450).

[0074] The third portion 630 of the flexible printed circuit board 601 may be disposed above the protective bracket 155. The third portion 630 may extend along the upper surface of the protective bracket 155 from the second portion 620 having a bent form.

[0075] According to various embodiments, the length of the third portion 630 may be the same as or similar to the length of the protection bracket 155. The width of the third portion 630 may be equal to or smaller than the width of the protection bracket 155.

[0076] According to various embodiments, the third portion 630 may be longer than the fourth portion 640. As the length of the third portion 630 increases, the third portion 630 may effectively cope with the movement of the battery 140, thereby preventing damage caused by impact.

[0077] According to various embodiments, the third portion 630 may include a V or W bent portion 631 at least partially thereof. The V or W bent portion 631 may improve the buffering function of the third portion 630 when the jelly roll in the battery 140 moves (eg, when the electronic device 101 is subjected to a drop shock).

[0078] although Figure 6 An example is shown in which the third portion 630 includes one V or W bent portion 631, but the present disclosure is not limited thereto. For example, a plurality of V or W bent portions 631 may be arranged at specific intervals.

[0079] Figure 7aA battery protection module according to an embodiment of the present disclosure is shown.

[0080] Reference Figure 7a , the battery protection module 150 may include a substrate 710, a protection IC 720, a first terminal tab 151, and a second terminal tab 152. The substrate 710 may have the protection IC 720, the first terminal tab 151, and the second terminal tab 152 mounted thereon, and may electrically connect the protection IC 720, the first terminal tab 151, and the second terminal tab 152. The protection IC 720 may prevent overcharge or overdischarge of the battery 140, and may protect the battery 140 from overcurrent. The first terminal tab 151 may be connected to a first electrode (positive electrode plate) of the battery 140, and the second terminal tab 152 may be connected to a second electrode (negative electrode plate) of the battery 140.

[0081] According to various embodiments, the substrate 710 may include a connection portion 710 a connected to the flexible printed circuit board 180 on a side surface (a surface other than a surface facing the main circuit board 130 or the battery 140 ) thereof.

[0082] According to an embodiment, the width T1 of the connection portion 710a may be greater than the width T2 of another area of ​​the substrate 710. The width of the first portion 410 of the flexible printed circuit board 180 connected to the connection portion 710a may be determined based on the width T1 of the connection portion 710a. As the width T1 of the connection portion 710a increases, the resistance in the first to third portions 410, 420, and 430 of the flexible printed circuit board 180 may be reduced. According to various embodiments, the connection portion 710a may be disposed above a partition between the main circuit board 130 and the battery 140 (refer to Figure 8 ).

[0083] Figure 7b is a cross-sectional view of a substrate included in a battery protection module according to an embodiment of the present disclosure.

[0084] Reference Figure 7b , the substrate 710 may include a fixed area 711 and a flexible area 712 .

[0085] The fixing region 711 according to various embodiments may be a region where prepreg (PPG) 711a and base films 711b (including Cu) are alternately stacked with each other. The fixing region 711 may have the protection IC 720 mounted thereon.

[0086] The flexible region 712 according to various embodiments may be a region from which the prepreg (PPG) 711a is at least partially removed. The flexible region 712 may include a cover film 712a, and the base film 711b (containing Cu) is coated with the cover film 712a. Due to the removal of the prepreg (PPG) 711a, the flexible region 712 may have flexibility. The flexible region 712 may include a connector 712b for connecting the flexible printed circuit board 180.

[0087] Figure 8 is a cross-sectional view of components around a main circuit board and a battery according to an embodiment of the present disclosure.

[0088] Reference Figure 8 , the electronic device 101 may include a battery placement area 810 on which the battery 140 is placed.

[0089] The battery seating area 810 according to various embodiments may include a battery separator 820 for separating the battery 140 from the main circuit board 130. The battery separator 820 may be provided to have a certain gap with the battery 140, and thus may cope with movement of the battery 140.

[0090] According to various embodiments, the battery separator 820 may have a relatively small height in a region adjacent to the connection portion 710a of the battery protection module 150. The connection portion 710a of the battery protection module 150 may be a portion to which the flexible printed circuit board 180 is connected. The connection portion 710a of the battery protection module 150 may have a greater width than that of other portions of the battery protection module 150 to ensure the width of the flexible printed circuit board 180.

[0091] The connection portion 710 a of the battery protection module 150 may be disposed above the battery separator 820 to have a certain gap with the battery separator 820 and cover the battery separator 820 when viewed from above.

[0092] The flexible printed circuit board 180 may include a V or W bent portion above the main circuit board 130. When the jelly roll in the battery 140 moves (for example, when the electronic device 101 is subjected to a drop shock), the V or W bent portion allows the flexible printed circuit board 180 to extend, thereby performing a buffering function.

[0093] Figure 9a An example of a protection bracket according to an embodiment of the present disclosure is shown.

[0094] Reference Figure 9aThe battery protection module 150 may be surrounded by a protection bracket 910 (eg, protection bracket 155). The protection bracket 910 may prevent the bag of the battery 140 from bursting when the jelly roll in the battery 140 moves (eg, when the electronic device 101 is subjected to a drop shock).

[0095] According to an embodiment, the protective bracket 910 may include an opening 911a in a side surface thereof (a surface that does not face the main circuit board 130 or the battery 140), through which the flexible printed circuit board 180 passes.
