[0008] (Background leading to the present disclosure) For example, an electronic device having a wiring structure in which a cable is inserted into a through hole provided in a wall separating two regions in a housing and the cable is wired is known.
[0009] However, an electronic device having the above wiring structure has a problem that when a cable is inserted into the through hole, the cable rubs against the wall defining the through hole and is damaged.

[0015] As shown in Figure 1, Figure 2, or Figure 3, the electronic device 1 comprises a first housing 3, a second housing 4, a cable 7, a circuit board 8, and an antenna 9.
[0016] As shown in Figures 3 and 4, the first housing 3 has an internal space. The internal space enclosed by the first housing 3 is referred to as the first region S1. The first housing 3 is made of metal. For example, the first housing 3 is made of a magnesium alloy or an aluminum alloy. A detailed explanation of the structure of the first housing 3 will be given later.
[0017] As shown in Figure 1, the second housing 4 is connectable to the first housing 3. For example, the second housing 4 can be connected by fitting it with the first housing 3. As shown in Figures 3 and 4, the second housing 4 houses a part of the first housing 3. The second housing 4 has an internal space. The internal space enclosed by the second housing 4 is called the second region S2. The second region S2 is adjacent to the first region S1. A part of the first housing 3 is housed within the second region S2 of the second housing 4. For example, the second housing 4 is made of resin.
[0018] The cable 7 is housed in the first housing 3 and the second housing 4. The cable 7 is located within the first area S1 and the second area S2.
[0019] The circuit board 8 is housed inside the first housing 3. The circuit board 8 is placed in the first region S1. The circuit board 8 is connected to the cable 7.
[0020] The antenna 9 is housed inside the second housing 4. The antenna 9 is positioned in the second region S2. The antenna 9 is connected to the circuit board 8, which is positioned in the first region S1, via a cable 7.
[0021] I will now explain the first enclosure 3.
[0022] As shown in Figures 3 and 4, the first housing 3 includes a first part 12 and a second part 14 that can be connected to the first part 12. The first part 12 and the second part 14 face each other.
[0023] The first part 12 is connectable to the second housing 4. The first part 12 includes a first wall 21, a second wall 22, and a third wall 23. The first wall 21, the second wall 22, and the third wall 23 are connected. The first wall 21 separates the first region S1 from the second region S2 adjacent to the first region S1. The second wall 22 is located within the second region S2. The third wall 23 has a surface in the first part 12 that faces the second part 14. The electronic device 1 has a space between the third wall 23 and the second part 14 that includes the first region S1.
[0024] The first wall 21 has a first portion 31 extending from the third wall 23 in a first direction Z1 away from the second part 14, and a second portion 32 extending from the third wall 23 in a second direction Z2 opposite to the first direction Z1. The first portion 31 has a greater length in the Z-axis direction than the second portion 32.
[0025] The first wall 21 has a first surface 41 on the side of the first region S1 and a second surface 42 on the side of the second region S2. The first portion 31 has a second surface 42. The second portion 32 has a first surface 41 and a second surface 42. In this embodiment, the first surface 41 is the surface located on the opposite side of the second surface 42.
[0026] As shown in Figures 4 and 5, the first wall 21 has a recess 51 and a groove 55.
[0027] The recess 51 is recessed in the thickness direction of the first wall 21 and in the direction from the second region S2 toward the first region S1. The recess 51 is recessed toward the fourth direction X2, which is opposite to the third direction X1 toward the second region S2 toward the first region S1 toward the second region S2. The recess 51 is recessed toward the fourth direction X2 toward the second surface 42. The recess 51 has a trapezoidal shape when viewed toward the fourth direction X2. The recess 51 is provided in the second portion 32.
[0028] As shown in Figures 3 and 4, a cable 7 can be placed in the groove 55. As shown in Figure 5, the groove 55 is provided in the second portion 32. The groove 55 is provided in the recess 51. The groove 55 penetrates in a third direction X1 from the first surface 41 toward the second surface 42. When viewed in the direction toward the thickness direction of the first wall 21, the groove 55 is arch-shaped. When viewed in the direction toward the fourth direction X2, the groove 55 is smaller than the recess 51. The length of the groove 55 in the X-axis direction is smaller than the length of the recess 51 in the X-axis direction. The length of the groove 55 in the X-axis direction is 0.1 times or more and 0.8 times or less the length of the recess 51 in the X-axis direction. Preferably, the length of the groove 55 in the X-axis direction is 0.2 times or more and 0.7 times or less the length of the recess 51 in the X-axis direction. More preferably, the length of the groove 55 in the X-axis direction is 0.3 times or more and 0.5 times or less the length of the recess 51 in the X-axis direction.
[0029] The groove 55 has a first defining wall surface 81, a second defining wall surface 82 facing the first defining wall surface 81, and a third defining wall surface 83 that intersects and connects with the first defining wall surface 81 and the second defining wall surface 82. In this specification, the length between the first defining wall surface 81 and the second defining wall surface 82 is described as the "width" of the groove 55. The width of the groove 55 is approximately the same as the diameter of the cross-sectional area of the cable 7. In this embodiment, "approximately" includes an error of 5% to 10%. As shown in Figure 5, when viewed in the direction toward the thickness direction of the first wall 21, the width of the groove 55 decreases in the direction away from the opening of the groove 55. For example, the length L2 of the groove 55 at the opening of the groove 55 is greater than the length L3 of the groove 55 near the third defining wall surface 83.
[0030] In this specification, the length from the edge defining the groove 55 to the third defining wall surface 83 in the first direction Z1 is described as the "depth" of the groove 55. As shown in Figure 5, the depth D1 of the groove 55 is greater than the width of the groove 55. The depth D1 is the length from the edge defining the groove 55 to the third defining wall surface 83 in the first direction Z1. The depth D1 is less than the length of the recess 51 in the Z-axis direction. The depth D1 is greater than the diameter of the cross-sectional area of the cable 7.
[0031] As shown in Figure 3, the second wall 22 extends from the first wall 21 in the direction from the first region S1 to the second region S2. The second wall 22 extends from the second part 32 in the direction from the first region S1 to the second region S2, that is, in the third direction X1. As shown in Figures 3 and 4, in the first part 12, the position of the second wall 22 in the Z-axis direction is further in the second direction Z2 than the position of the third wall 23 in the Z-axis direction.
[0032] The second wall 22 has a third surface 43 and a fourth surface 44 located opposite the third surface 43. The first wall 21 extends from the fourth surface 44 toward the first direction Z1. The second portion 32 extends from the fourth surface 44 toward the first direction Z1.
[0033] As shown in Figure 5, the second wall 22 has a through hole 61 that penetrates in a first direction Z1 from the third surface 43 to the fourth surface 44. The groove 55 and the through hole 61 are connected. The cross-sectional area of the through hole 61 is larger than that of the cable 7. The through hole 61 is larger than that of the groove 55. The opening area of the through hole 61 is larger than that of the groove 55.
[0034] The through hole 61 has a longitudinal direction. This longitudinal direction intersects with the first direction Z1 and moves away from the third wall 23.
[0035] The through hole 61 has a length L10 in the longitudinal direction (X-axis direction) and a length L20 in the short direction (Y-axis direction). Length L10 is greater than length L20. Length L10 is 1.2 times or more and 4 times or less the size of length L20. Preferably, length L10 is 1.5 times or more and 3.5 times or less the size of length L20. More preferably, length L10 is 2 times or more and 3 times or less the size of length L20.
[0036] The longitudinal length L10 of the through hole 61 is at least 1.5 times the depth D1 of the groove 55. Preferably, the length L10 is at least 2 to 5 times the depth D1. More preferably, the length L10 is at least 2.5 to 4 times the depth D1.
[0037] When viewed in the direction toward the second direction Z2, the through hole 61 has a rectangular shape. When viewed in the direction toward the second direction Z2, the through hole 61 has a rectangular shape with a longitudinal direction and a transverse direction.
[0038] The wall surface defining the recess 51 and the wall surface defining the through hole 61 are continuously connected. There is no step in the portion where the wall surface defining the recess 51 and the wall surface defining the through hole 61 are continuously connected. In the portion where the wall surface defining the recess 51 and the wall surface defining the through hole 61 are continuously connected, the length L1 between the wall surfaces defining the recess 51 is less than or equal to the length L20 between the wall surfaces defining the through hole 61. Preferably, the length L1 is approximately the same as the length L20.
[0039] The second wall 22 has a rib 65 projecting from the fourth surface 44 in a first direction Z1 along the edge defining the through hole 61. The rib 65 projects from the fourth surface 44 in the first direction Z1 for a length of 0.5 times or more the thickness of the second wall 22. Preferably, the rib 65 projects from the fourth surface 44 in the first direction Z1 for a length of 0.8 to 3 times the thickness of the second wall 22. More preferably, the rib 65 projects from the fourth surface 44 in the first direction Z1 for a length of 1.0 to 2 times the thickness of the second wall 22. The rib 65 is connected to the first wall 21.
[0040] The second part 14 is positioned further away from the first part 12 in the second direction Z2, which is opposite to the first direction Z1. Viewed from the thickness direction of the first wall 21, the length in the second direction Z2 from the edge defining the groove 55 to the second part 14 is less than or equal to the diameter of the cable 7. Preferably, viewed from the thickness direction of the first wall 21, the length in the second direction Z2 from the edge defining the groove 55 to the second part 14 is 0.8 times the diameter of the cable 7. More preferably, viewed from the thickness direction of the first wall 21, the length in the second direction Z2 from the edge defining the groove 55 to the second part 14 is 0.5 times the diameter of the cable 7.
[0041] In this embodiment, the operation of wiring the cable 7 in the electronic device 1 will be described. The explanation will assume that the cable 7 is wired in the direction from the second region S2 to the first region S1, but the cable 7 may also be wired in the direction from the first region S1 to the second region S2.
[0042] First, insert the cable 7 into the through-hole 61 in the direction from the fourth surface 44 toward the third surface 43. The cable 7 passes through the through-hole 61 for the length that is accommodated in the first housing 3. Also, when the cable 7 is inserted into the through-hole 61, it may receive a force in the direction from the second region S2 toward the first region S1.
[0043] Subsequently, insert the cable 7 into the recess 51 and the groove 55. With the cable 7 inserted into the through-hole 61, bend the cable 7 in the direction from the second region S2 toward the first region S1, and by receiving a force in the direction from the edge defining the groove 55 toward the third defining wall surface 83, the cable 7 is disposed in the groove 55.
[0044] Subsequently, connect the cable 7 and the substrate 8 in the first region S1, and connect the cable 7 and the antenna 9 in the second region S2. For example, the cable 7 is connected to the substrate 8 and the antenna 9 by solder.
[0045] Subsequently, connect the first part 12 and the second part 14. For example, the first part 12 and the second part 14 are connected by a connecting component. The connecting component may be a screw or a rivet.
[0046] Subsequently, connect the first housing 3 and the second housing 4. For example, the first housing 3 and the second housing 4 are connected by fitting the first housing 3 and the second housing 4 together.
[0047] The effects of the electronic device 1 in the present embodiment will be described.
[0048] The electronic device 1 includes a first wall 21, a second wall 22, and a cable 7. The first wall 21 separates a first region S1 and a second region S2 adjacent to the first region S1. The first wall 21 has a first surface 41 on the first region S1 side and a second surface 42 on the second region S2 side. The first wall 21 has a groove 55 penetrating in a third direction X1 from the first surface 41 toward the second surface 42. The second wall 22 extends from the first wall 21 in a direction from the first region S1 toward the second region S2. The second wall 22 has a third surface 43 and a fourth surface 44 located on the opposite side of the third surface 43. The second wall 22 has a through hole 61 penetrating in a first direction Z1 from the third surface 43 toward the fourth surface 44. The cable 7 is disposed in the groove 55. The groove 55 and the through hole 61 are connected. The through hole 61 is larger than the groove 55.
[0049] With such a configuration, the electronic device 1 can suppress damage to the cable 7. Since the through hole 61 is larger than the groove 55, when wiring the cable 7 from the second region S2 to the first region S1, it is possible to suppress the cable 7 from rubbing against the through hole 61, so that damage to the cable 7 can be suppressed. Further, since the cable 7 is disposed in the groove 55, the cable 7 is likely to be maintained at the wired position.
[0050] The depth D1 of the groove 55 is larger than the width of the groove 55.
[0051] With such a configuration, the cable 7 can be more maintained in the state of being disposed in the groove 55, and it becomes easier to be maintained at the wired position of the cable 7.
[0052] When viewed in the direction toward the thickness direction of the first wall 21, the width of the groove 55 becomes smaller in the direction away from the opening of the groove 55.
[0053] With such a configuration, it becomes easier to insert the cable 7 into the groove 55, so that damage to the cable 7 can be suppressed.
[0054] The through hole 61 has a longitudinal direction. The longitudinal direction intersects the first direction Z1 and is a direction away from the first wall 21.
[0055] With this configuration, the electronic device 1 can further suppress damage to the cable 7. The cable 7 may be subjected to a force in the direction from the second region S2 to the first region S1. When the cable 7 is subjected to a force in the direction from the second region S2 to the first region S1, the cable 7 inserted into the through hole 61 may move in the direction from the second region S2 to the first region S1. Because the through hole 61 has a longitudinal direction, damage to the cable 7 due to contact and rubbing against the edge of the through hole 61 when the cable 7 inserted into the through hole 61 moves in the direction from the second region S2 to the first region S1 can be suppressed.
[0056] When viewed in the direction toward the second direction Z2, the through hole 61 has a rectangular shape.
[0057] With this configuration, the electronic device 1 can further suppress damage to the cable 7. Because the through-hole 61 has a rectangular shape, burrs can be suppressed on the wall surface defining the through-hole 61, thus further suppressing damage to the cable 7.
[0058] The first wall 21 extends from the fourth surface 44 toward the first direction Z1. The second wall 22 has a rib 65 projecting toward the first direction Z1 from the fourth surface 44 along the edge defining the through hole 61.
[0059] The presence of ribs 65 in the second wall 22 prevents liquid, such as water, from entering the first region S1 through the through-holes 61 when liquid enters the second region S2 of the electronic device 1 from the outside.
[0060] The first wall 21 has a recess 51 that is recessed in the thickness direction of the first wall 21 and in the direction from the second region S2 toward the first region S1. The groove 55 is provided in the recess 51.
[0061] The first wall 21 has a recess 51, and a groove 55 is provided in the recess 51, which reduces the area of the wall surface defining the groove 55 that the cable 7 contacts. By reducing the area of the wall surface defining the groove 55 that the cable 7 contacts, damage caused by the cable 7 contacting and rubbing against the groove 55 can be suppressed.
[0062] The wall surface defining the recess 51 and the wall surface defining the through hole 61 are continuously connected. The groove 55 is provided in the recess 51.
[0063] This configuration makes it easier to position the cable 7 in the groove 55 after inserting it into the through hole 61. This improved ease of positioning the cable 7 in the groove 55 enhances work efficiency.
[0064] In the portion where the wall surface defining the recess 51 and the wall surface defining the through hole 61 are continuously connected, the length between the wall surfaces defining the recess 51 and the length between the wall surfaces defining the through hole 61 are approximately the same.
[0065] This configuration makes it easier to position the cable 7 in the groove 55 after inserting it into the through hole 61. This improved positioning of the cable 7 in the groove 55 further enhances work efficiency.
[0066] The electronic device 1 comprises a first housing 3 including a first part 12 which includes a first wall 21 and a second wall 22, and a second part 14 which is connectable to the first part 12. The second part 14 is positioned further away from the first part 12 in a second direction Z2 opposite to the first direction Z1. The first wall 21 extends from the fourth surface 44 toward the first direction Z1. Viewed from the thickness direction of the first wall 21, the length in the second direction Z2 from the edge defining the groove 55 to the second part 14 is less than or equal to the diameter of the cable 7.
[0067] With this configuration, after the cable 7 is placed in the groove 55, the cable 7 can be maintained in its position. When the cable 7 is subjected to a force in the second direction Z2 and moves away from the groove 55, the cable 7 comes into contact with the second part 14. When the cable 7 is in contact with the second part 14, the second part 14, when subjected to a force in the Y-axis direction, comes into contact with the first defining wall surface 81 or the second defining wall surface 82 that defines the groove 55, or with the edge that defines the groove 55. Therefore, the cable 7 is stably maintained in the position of the groove 55 in the Y-axis direction (fifth direction Y1 and sixth direction Y2) that intersects with the direction in the third direction X1 when viewed in the direction in the first direction Z1.
[0068] The electronic device 1 comprises a first housing 3 including a first part 12 which includes a first wall 21 and a second wall 22, and a second housing 4 which houses a part of the first housing 3. The first housing 3 is made of metal. The first region S1 is the internal space enclosed by the first housing 3. The second region S2 is the internal space enclosed by the second housing 4. The second wall 22 is located within the second region S2.
[0069] With this configuration, even if electromagnetic waves are generated from an object housed in the first region S1 or the second region S2, the impact on the outside of the first region S1 or the second region S2 can be suppressed. For example, if a substrate is housed in the first region S1 and an antenna is housed in the second region S2, even if electromagnetic waves are generated from the antenna, the substrate will be less affected by the electromagnetic waves from the antenna.
[0070] The electronic device 1 further comprises a substrate 8 located in the first region S1. The substrate 8 is connected to a cable 7.
[0071] The first region S1 is equipped with a substrate 8, and the substrate 8 is connected by a cable 7, so that the substrate 8 can be electrically connected to external electronic components via the cable 7. Furthermore, the electronic device 1 can safely electrically connect the substrate 8 to external electronic components because damage to the cable 7 can be suppressed.
[0072] The electronic device 1 further includes an antenna 9 located in the second region S2. The antenna 9 is connected to a circuit board 8 located in the first region S1 via a cable 7.
[0073] With this configuration, the cable 7 can electrically connect the substrate 8 located in the first region S1 and the antenna 9 located in the second region S2. Furthermore, the electronic device 1 can safely connect the substrate 8 and the antenna 9 because it can suppress damage to the cable 7.
[0074] Although the electronic device 1 of this embodiment has been described as comprising a first housing 3, a second housing 4, a cable 7, a circuit board 8, and an antenna 9, it is not limited to these. For example, the electronic device 1 may not include the second housing 4, the circuit board 8, and the antenna 9.
[0075] The electronic device 1 may have one cable 7 or multiple cables 7.
[0076] Although the first housing 3 was described as being made of metal, it is not limited to this. For example, the first housing 3 may be made of resin.
[0077] Although the second housing 4 was described as being made of resin, it is not limited to this. For example, the second housing 4 may be made of metal and resin.
[0078] Although it was explained that the first enclosure 3 includes the first part 12 and the second part 14, the first enclosure 3 does not necessarily have to include the second part 14.
[0079] Although an example has been described in which the electronic device 1 comprises a first part 12 including a first wall 21, a second wall 22, and a third wall 23, it is not limited to this. For example, the electronic device 1 may also comprise a first wall 21 and a second wall 22. In other words, the electronic device 1 does not necessarily have to comprise a third wall 23.
[0080] Although Figures 3 and 4 show an example in which the first wall 21, the second wall 22, and the third wall 23 are connected, the design is not limited to this. For example, the first wall 21, the second wall 22, and the third wall 23 do not have to be connected. The third wall 23 may be detachably connected to the first wall 21 and the second wall 22. For example, the third wall 23 may be connected to the first wall 21 and the second wall 22 by connecting components.
[0081] Although it was explained that the first wall 21 extends from the fourth surface 44 toward the first direction Z1, the first wall 21 does not necessarily have to extend from the fourth surface 44 toward the first direction Z1.
[0082] Although it has been explained that the first wall 21 has a first portion 31 and a second portion 32, it is not limited to this. For example, the first wall 21 does not have to have a first portion 31.
[0083] The first wall 21 may have multiple grooves 55, and the second wall 22 may have one through hole connected to the multiple grooves 55.
[0084] Although it has been explained that the first wall 21 has a recess 51, the first wall 21 does not necessarily have to have a recess 51.
[0085] The first wall 21 may have one recess 51 or multiple recesses 51. When the first wall 21 has multiple recesses 51, the multiple recesses 51 may be spaced apart in the Y-axis direction.
[0086] The first wall 21 may have one groove 55 or multiple grooves 55. When the first wall 21 has multiple grooves 55, the multiple grooves 55 may be spaced apart in the Y-axis direction and provided on the first wall 21.
[0087] Although it was explained that the groove 55 has an arch shape, the groove 55 does not have to be arch-shaped. For example, the groove 55 may be rectangular or trapezoidal.
[0088] Although it was explained that the width of the groove 55 is approximately the same as the diameter of the cross-sectional area of the cable 7, the width of the groove 55 does not have to be approximately the same as the diameter of the cross-sectional area of the cable 7. For example, the width of the groove 55 may be larger than the diameter of the cross-sectional area of the cable 7.
[0089] It has been explained that, when viewed in the thickness direction of the first wall 21, the width of the groove 55 decreases as it moves away from the opening of the groove 55, but this is not limited to this. For example, when viewed in the thickness direction of the first wall 21, the width of the groove 55 may increase as it moves away from the opening of the groove 55.
[0090] Although it was explained that the depth D1 of the groove 55 is greater than the width of the groove 55, this is not the only limitation. For example, the depth D1 of the groove 55 may be approximately the same as the width of the groove 55.
[0091] Although it was explained that the depth D1 of the groove 55 is greater than the diameter of the cross-sectional area of the cable 7, this is not the only limitation. For example, the depth D1 of the groove 55 may be between 0.6 and 0.9 times the diameter of the cross-sectional area of the cable 7.
[0092] In the first part 12, the position of the second wall 22 in the Z-axis direction is described as being further away in the second direction Z2 than the position of the third wall 23 in the Z-axis direction, but this is not limited to this. For example, in the first part 12, the position of the second wall 22 in the Z-axis direction may be approximately the same as the position of the third wall 23 in the Z-axis direction.
[0093] Although it has been explained that the second wall 22 extends from the first wall 21 in the direction from the first region S1 to the second region S2, this is not the only way it can extend. For example, the second wall 22 may extend from the first wall 21 in the direction from the first surface 41 to the second surface 42.
[0094] The second wall 22 may have one through hole 61 or may have multiple through holes 61. When the second wall 22 has multiple through holes 61, the multiple through holes 61 may be provided in the second wall 22 with spacing in the Y-axis direction.
[0095] It has been explained that, at the point where the wall surface defining the recess 51 and the wall surface defining the through hole 61 connect, the length L1 of the first wall 21 is less than or equal to the length L20 of the through hole 61, but this is not limited to this. For example, at the point where the wall surface defining the recess 51 and the wall surface defining the through hole 61 connect, the length L1 of the first wall 21 may be greater than the length L20 of the through hole 61.
[0096] Although it has been explained that the through hole 61 has a longitudinal direction, the through hole 61 does not necessarily have to have a longitudinal direction.
[0097] Although it has been explained that the through-hole 61 has a rectangular shape when viewed in the direction toward the second direction Z2, it is not limited to this. For example, it may have a trapezoidal or elliptical shape. When viewed in the direction toward the second direction Z2, the through-hole 61 may have a trapezoidal shape in which the length in the Y-axis direction is shorter in the direction approaching the first wall 21, that is, toward the fourth direction X2.
[0098] Although it was explained that the second wall 22 has ribs 65, the second wall 22 does not necessarily have to have ribs 65.
[0099] It has been explained that the second part 14 is positioned further away from the first part 12 in the second direction Z2, which is opposite to the first direction Z1, but this is not limited to this. For example, a part of the second part 14 may be in contact with the first part 12. The third surface 43 may be in contact with the first part 12. The opening of the groove 55 may be blocked by the second part 14.
