[0013] Hereinafter, an electronic device according to the present embodiment will be described with reference to the drawings. (electronic equipment) The electronic device 1 according to this embodiment is a tablet terminal, a notebook personal computer, a smartphone, etc. As shown in Fig. 1, the electronic device 1 mainly includes a housing 2, electronic components 3, a board 4, and a battery 5.

[0014] The housing 2 has a flat, hollow box shape. The housing 2 has a first plate-shaped portion 21 and a second plate-shaped portion (not shown). The housing 2 is formed, for example, in a rectangular shape when viewed from a direction perpendicular to the first plate-shaped portion 21. In other words, the first plate-shaped portion 21 and the second plate-shaped portion (not shown) are each rectangular.

[0015] (direction definition) In this embodiment, the direction in which the inner surface 21f (see FIG. 1) of the first plate-shaped portion 21 faces is referred to as the first direction D1. The direction along the long side of the rectangular first plate-shaped portion 21 is referred to as the second direction D2. The direction along the short side of the first plate-shaped portion 21 is referred to as the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to one another. The first direction D1 is also the thickness direction of the flat housing 2. Hereinafter, viewing from the first direction D1 may be referred to as a "planar view."

[0016] A display (not shown) is provided on a second plate-shaped portion (not shown) of the housing 2. The display is made up of a liquid crystal display panel or the like. The display displays images, videos, etc. The display may be capable of receiving touch input.

[0017] 1 and 2, electronic components 3, a board 4, a battery 5, a storage device 6 such as an SSD, and various other components (not shown) are housed in a housing 2. The electronic components 3, the board 4, and the battery 5 are fixed to an inner surface 21f of the housing 2.

[0018] The electronic component 3 is, for example, an RTC battery 31. One end of a cable 35 is connected to the RTC battery 31. The other end of the cable 35 is electrically connected to a nonvolatile memory module (not shown) with an RTC function mounted on the substrate 4. The RTC battery 31, separate from the battery 5, stores power to be supplied to the nonvolatile memory module (not shown) with an RTC function.

[0019] The substrate 4 is, for example, a motherboard or the like on which various elements such as a processor, a nonvolatile memory module, etc. are mounted. The substrate 4 is disposed parallel to the inner surface 21f of the first plate-shaped portion 21. The substrate 4 is fixed to the inner surface 21f with screws (not shown) or the like. A connector 41 to which the other end of the cable 35 is connected is mounted on the substrate 4.

[0020] The battery 5 stores power to be supplied to each component of the electronic device 1. As shown in FIGS. 1 to 3, the battery 5 has a rectangular parallelepiped shape as a whole. The battery 5 has a rectangular shape in a plan view. The long sides 5a of the battery 5 extend in the second direction D2. The short sides 5b of the battery 5 extend in the third direction D3. The battery 5 has a flat shape, and the thickness in the first direction D1 is smaller than the long sides 5a and the short sides 5b.

[0021] As shown in FIGS. 3 and 4, the battery 5 has a cell 51, a frame 52 that holds the cell 51, and a bottom cover 53 and a top cover 54 that cover the cell 51 from both sides in the first direction D1. The frame 52 integrally includes a bottom frame portion 52a that supports the lower surface of the cell 51 and a side frame portion 52b that stands upright from the outer periphery of the bottom frame portion 52a to one side in the first direction D1 (the side away from the inner surface 21f). The cell 51 is housed in a space surrounded by the frame 52, the bottom cover 53, and the top cover 54.

[0022] The cells 51 are lithium ion batteries, nickel-metal hydride batteries, or the like, and store power to be supplied to each component within the electronic device 1. The specific configuration of the battery 5 can be changed as appropriate. For example, a plurality of cells 51 may be housed within the frame 52.

[0023] 1 and 3, the frame 52 is provided with a plurality of brackets 55 and a plurality of co-fastening portions 56 for fixing the battery 5 to the inner surface 21f of the housing 2. The brackets 55 and co-fastening portions 56 are arranged at intervals along the outer periphery of the frame 52. Each bracket 55 is fixed to the inner surface 21f with a screw or the like (not shown).

[0024] As shown in FIGS. 1 to 3, the number of co-tightening portions 56 in this embodiment is two. Each co-tightening portion 56 is disposed on a side surface 52s of the frame 52. However, the number of co-tightening portions 56 can be changed and may be one, or may be three or more. The positions of the co-tightening portions 56 may also be changed.

[0025] The co-fastening portion 56 is fastened together with the substrate 4 to the inner surface 21f of the first plate-shaped portion 21 by a screw 59. More specifically, the substrate 4 has an insertion hole (not shown) formed therein for inserting the screw 59. Furthermore, the first plate-shaped portion 21 has a screw hole formed therein for screwing the screw 59. The co-fastening portion 56 and the substrate 4 are sandwiched between the head of the screw 59 and the first plate-shaped portion 21, thereby fixing the co-fastening portion 56 and the substrate 4 to the first plate-shaped portion 21.

[0026] The frame 52 has a guide structure 70 that guides the cables 35 extending from the electronic components 3. The guide structure 70 in this embodiment has a first guide portion 70A, a second guide portion 70B, and a third guide portion 70C.

[0027] The first guide portion 70A and the second guide portion 70B are provided on a side surface 52s of the frame 52. The "side surface 52s" refers to a surface of the frame 52 facing the third direction D3. The first guide portion 70A and the second guide portion 70B are provided at an interval in the second direction D2.

[0028] 2 to 5, each of the first guide portion 70A and the second guide portion 70B integrally includes a base portion 71 and a locking piece 72. The base portion 71 is connected to the side surface 52s of the frame 52 and protrudes to the other side in the third direction D3.

[0029] The locking piece 72 extends in the first direction D1 from the tip of the base 71. Here, as shown in Figures 3 and 4, the locking piece 72A of the first guide portion 70A protrudes from the base 71 to one side in the first direction D1 (a direction away from the inner surface 21f). As shown in Figures 3 and 5, the locking piece 72B of the second guide portion 70B protrudes from the base 71 to the other side in the first direction D1 (a direction toward the inner surface 21f).

[0030] 2, 3, and 6, the third guide portion 70C is provided in the co-tightening portion 56. The third guide portion 70C protrudes in the second direction D2 from a side surface 56s of the co-tightening portion 56. When viewed from the co-tightening portion 56, the side surface 56s of the co-tightening portion 56 faces in the direction in which the first guide portion 70A and the second guide portion 70B are arranged.

[0031] The third guide portion 70C integrally includes a base portion 71 and a locking piece 72C. The base portion 71 is connected to the side surface 56s and protrudes toward one side in the second direction D2. The locking piece 72C protrudes from the tip of the base portion 71 toward one side in the first direction D1 (a direction away from the inner surface 21f). In the second direction D2, the locking pieces 72A, 72B, and 73C are arranged in this order. The locking pieces 72A and 72C protrude in a direction different from the direction in which the locking piece 72B protrudes. This configuration can prevent the cable 35 from falling off the locking pieces 72A to 72C.

[0032] As shown in FIG. 2, the cable 35 is connected to the connector 41 on the board 4 via the first guide portion 70A, the second guide portion 70B, and the third guide portion 70C. The cable 35 is inserted between the locking pieces 72A, 72B, and 72C of the first guide portion 70A, the second guide portion 70B, and the third guide portion 70C and the side surfaces 52s and 56s. This configuration allows the cable 35 to be routed in a narrow space along the side surface 52s of the frame 52 and the side surface 56s of the co-tightening portion 56. This also prevents the cable 35 from being positioned away from the side surfaces 52s and 56s and being pinched between the cable 35 and other components.

[0033] As described above, the electronic device 1 of this embodiment includes the housing 2, the electronic component 3 housed in the housing 2, and the battery 5 housed in the housing 2. The battery 5 has the cell 51 and the frame 52 that holds the cell 51. The frame 52 has a guide structure 70 that guides the cable 35 extending from the electronic component 3. With this configuration, the cable 35 can be routed inside the housing 2 while preventing the cable 35 from being pinched.

[0034] The guide structure 70 also includes a first guide portion 70A and a second guide portion 70B. The first guide portion 70A and the second guide portion 70B each have a base portion 71 protruding from the side surface 52s of the frame 52 and locking pieces 72A, 72B provided at the tip of the base portion 71. The first guide portion 70A and the second guide portion 70B are arranged at an interval along the side surface 52s of the frame 52. This configuration allows the cable 35 to be positioned in a narrow space along the side surface 52s of the battery 5. This allows the electronic device 1 to be miniaturized while preventing the cable 35 from being pinched.

[0035] Furthermore, the direction in which locking piece 72A in first guide portion 70A protrudes from base portion 71 is different from the direction in which locking piece 72B in second guide portion 70B protrudes from base portion 71 (see FIGS. 4 and 5). More specifically, locking piece 72A protrudes away from inner surface 21f, and locking piece 72B protrudes toward inner surface 21f. This configuration prevents cable 35 from coming off multiple locking pieces 72, allowing guide structure 70 to more reliably guide cable 35.

[0036] The electronic device 1 further includes a substrate 4 to which a cable 35 is connected. The frame 52 has a co-tightening portion 56 that is fastened to the housing 2 together with the substrate 4, and the guide structure 70 includes a third guide portion 70C that protrudes from the co-tightening portion 56. This configuration makes it possible to effectively use the co-tightening portion 56 to guide the cable 35. Furthermore, the cable 35, guided by the third guide portion 70C near the co-tightening portion 56, can be reliably guided toward the substrate 4.

[0037] Furthermore, the co-tightening portion 56 protrudes from the side surface 52s in a direction (direction D3) that is substantially perpendicular to a first guide direction (direction D2) in which the cable 35 is guided by the first guide portion 70A and the second guide portion 70B. The second guide direction (direction D3) in which the cable 35 is guided by the third guide portion 70C is substantially perpendicular to the first guide direction. With this configuration, the substantially perpendicularly bent portion of the cable 35 can be guided by the guide portions 70A to 70C.

[0038] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the guide structure 70 includes the first guide portion 70A, the second guide portion 70B, and the third guide portion 70C. However, the number and layout of the guide portions 70A to 70C can be changed as appropriate depending on the routing path of the cable 35.

[0039] In addition, in the above embodiment, the RTC battery 31 is exemplified as the electronic component 3, but the electronic component 3 is not limited to the RTC battery 31 as long as it is housed in the housing 2 and has a cable 35. For example, the electronic component 3 may be a cooling fan, a speaker, or the like.

[0040] Furthermore, the electronic device 1 is not limited to a tablet terminal, but may be a notebook personal computer, a smartphone, a game terminal, or the like.

[0041] In addition, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and variations may be combined as appropriate, without departing from the spirit of the present invention.
