Description

electronic equipment

[0001] The present disclosure relates to an electronic device equipped with an antenna.

[0002] An electronic device equipped with an antenna is disclosed in Patent Document 1. In the electronic device disclosed in Patent Document 1, an antenna, a circuit board, and a battery pack are housed inside a housing. The antenna and the circuit board are connected via a cable.

[0003] International Publication No. 2016 / 125723

[0004] In the electronic device disclosed in Patent Document 1, the battery pack is located between the antenna and the circuit board. The cable connecting the antenna and the circuit board is routed around the battery pack. In this case, the cable that bypasses the battery pack occupies part of the space in the housing. This reduces the space available for arranging other components inside the housing.

[0005] Therefore, an object of the present disclosure is to solve the above-mentioned problem and to provide an electronic device that can suppress the reduction in space caused by the arrangement of a cable connecting an antenna and a board.

[0006] In order to achieve the above object, the electronic device according to the present disclosure may employ, for example, the following configurations (1) to (13).

[0007] (1) One configuration example of an electronic device of the present disclosure includes: an antenna; a control unit that controls the antenna; a cable that connects the antenna and the control unit; a battery pack having a battery, a protection circuit electrically connected to the battery, and a first cover that covers the battery and the protection circuit; and a second cover that is located at a position that overlaps at least the protection circuit of the battery pack when viewed along a thickness direction of the battery pack, wherein the length of the protection circuit in the thickness direction is shorter than the length of the battery in the thickness direction, and the second cover has a groove that is recessed in the thickness direction at a position that overlaps the protection circuit when viewed along the thickness direction on a surface on the opposite side to the battery pack in the thickness direction, and a portion of the cable is housed in the groove.

[0008] According to the configuration (1), a groove is provided at a position overlapping with the protection circuit when viewed along the thickness direction, and a portion of the cable is housed in the groove. This prevents the increase in the size of the electronic device in the thickness direction. Furthermore, compared to a configuration in which a portion of the cable is housed outside the groove, the free space in the electronic device when viewed along the thickness direction can be increased. Furthermore, the groove allows the cable to be positioned.

[0009] (2) In the configuration of (1), the second cover may be located so as to overlap the battery and the protection circuit when viewed along the thickness direction, and may be made of metal.

[0010] The thickness of the protection circuit is less likely to change than the battery. The thickness of the electronic device is set to a length that takes into account changes in the thickness of the battery and the protection circuit. Therefore, if a groove is provided at a position that overlaps with the battery when viewed along the X direction, the thickness of the electronic device will increase by the amount of the groove. According to the configuration (2), the groove is provided at a position that overlaps with the protection circuit, whose thickness is less likely to change, rather than at a position that overlaps with the battery when viewed along the thickness direction. Therefore, the thickness of the electronic device can be made thinner than in a configuration in which the groove is provided at a position that overlaps with the battery when viewed along the thickness direction.

[0011] According to the configuration (2), the second cover is located in a position overlapping the battery when viewed along the thickness direction and is made of metal, so that heat generated by the battery can be dissipated by the second cover.

[0012] (3) In the configuration of (2), the second cover may be electrically connected to a ground electrode of the electronic device.

[0013] According to the configuration (3), the second cover electrically connected to the ground electrode functions as a shielding member for shielding electromagnetic waves, thereby reducing the influence of electromagnetic waves on the cable placed in the groove.

[0014] (4) In any one of the configurations (1) to (3), the depth of the groove in the thickness direction may be equal to or greater than the length of the cable housed in the groove in the thickness direction.

[0015] If the depth of the groove in the thickness direction is shorter than the length of the cable housed in the groove in the thickness direction, part of the cable will be located outside the groove. In this case, the thickness of the electronic device will increase. On the other hand, according to the configuration (4), the depth of the groove in the thickness direction is equal to or greater than the length of the cable housed in the groove in the thickness direction, so the entire cable is housed within the groove. Therefore, the increase in the thickness of the electronic device can be suppressed.

[0016] When the second cover is connected to the ground electrode, a configuration in which the entire cable is housed within the groove can reduce the effects of electromagnetic waves on the cable compared to a configuration in which part of the cable is located outside the groove.

[0017] (5) In any one of the configurations (1) to (4), the surfaces that form the grooves may be smoothly curved.

[0018] If the surfaces that form the grooves are curved, cracks may occur at the curved portions. According to the configuration (5), the surfaces that form the grooves are smoothly curved. Therefore, with the configuration (5), the possibility of cracks occurring can be reduced compared to a configuration in which the surfaces that form the grooves are curved.

[0019] (6) In the configuration of (5), the cable may be a coaxial cable having a circular cross section, and the surface constituting the groove may be curved at the innermost part of the groove with the same or approximately the same curvature as the circular cross section of the coaxial cable.

[0020] According to the configuration (6), the surface forming the groove is curved at the innermost portion of the groove with the same or approximately the same curvature as the circular cross section of the cable, which is a coaxial cable. Therefore, the outer surface of the cable and the surface forming the groove face each other at a generally constant distance in the radial direction of the cross section of the cable. This reduces variations in the current flowing through the cable due to external factors. As a result, unintended changes in the characteristics of the antenna connected to the cable can be reduced.

[0021] (7) In any one of the configurations (1) to (6), the cable may further include a fastener for fixing the wiring position of the cable, and the cable may include a first portion located between the antenna and the groove, a second portion located in the groove, and a third portion located between the groove and the control unit, and the fastener may fix the wiring position of the cable in at least one of the first portion and the third portion.

[0022] According to the configuration of (7), the fastening portion can reduce displacement of the cable in at least one of the first and third portions. Meanwhile, the second portion of the cable is housed in the groove, so it is less likely to be displaced even without being held down by the fastening portion. Since no fastening portion is required for the second portion, the structure of the electronic device can be simplified.

[0023] (8) In any one of the configurations (1) to (7), the battery pack may be rectangular when viewed along the thickness direction, and the groove portion may extend from one of two long sides of the rectangle to the other.

[0024] According to the configuration of (8) above, the groove can be made shorter than in a configuration in which the groove extends from one short side to the other of the rectangular battery pack.

[0025] (9) In the configuration of (8), the device may further include a connector connected to the cable and electrically connected to the control unit, and the battery pack may be located between the antenna and the connector in a direction along the short side of the rectangle.

[0026] According to the configuration of (9), the battery pack is located between the antenna and the connector in the direction along the short side of the rectangular battery pack, which allows the cable connecting the antenna and the control unit to be shorter than in a configuration in which the battery pack is located between the antenna and the connector in the direction along the long side of the rectangular battery pack.

[0027] (10) In the configuration of (8) or (9), an electronic component may be further provided that is arranged alongside the battery pack in a direction along the long side of the rectangle, and the groove may be located on the opposite side of the electronic component with respect to a center position of the battery pack in the direction along the long side of the rectangle.

[0028] According to the configuration (10), the groove is located on the opposite side of the electronic components from the center of the battery pack in the direction along the long sides of the rectangular battery pack. That is, the cables housed in the groove are located away from the electronic components. This reduces the electrical influence between the electronic components and the cables housed in the groove.

[0029] (11) In any one of the configurations (8) to (10), the groove may be parallel or approximately parallel to a short side of the rectangle.

[0030] According to the configuration of (11), the groove is parallel or approximately parallel to the short side of the rectangular battery pack, which allows the length of the groove provided in the second cover to be shortened.

[0031] (12) In any one of the configurations (1) to (11), a rib may be further provided that is located on the same side of the second cover as the battery pack in the thickness direction and extends parallel or approximately parallel to the groove portion, and the groove portion may be provided in a curved portion where a part of the second cover is bent toward the battery pack in the thickness direction, and the rib may face and be in contact with the curved portion in a direction perpendicular to the thickness direction and the direction in which the rib extends.

[0032] According to the configuration (12) above, the rib can position the second cover in a direction perpendicular to the thickness direction and the direction in which the rib extends.

[0033] (13) In any one of the configurations (1) to (12), a wall portion may be further provided that is located on the opposite side of the battery pack from the second cover in the thickness direction and faces the second cover in the thickness direction, and the thickness-wise distance between the wall portion and the portion of the second cover excluding the groove portion may be shorter than the thickness-wise length of the cable housed in the groove portion.

[0034] According to the configuration (13), the distance in the thickness direction between the wall portion and the portion of the second cover excluding the groove portion is shorter than the length in the thickness direction of the cable housed in the groove portion, thereby making it possible for the wall portion to prevent the cable from slipping out of the groove portion.

[0035] According to the electronic device according to the present disclosure, it is possible to suppress a reduction in space due to the arrangement of a cable connecting the antenna and the board.

[0037] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiment. In addition, substantially the same components in the drawings are designated by the same reference numerals.

[0038] In addition, for the sake of convenience, the following uses terms indicating directions such as "up," "down," and "height," assuming a state of normal use, but this does not mean to limit the state of use of the electronic device according to the present invention.

[0039] (Embodiment) The configuration of an electronic device according to an embodiment of the present disclosure will be described. The electronic device according to an embodiment of the present disclosure is, for example, a game device, a smartphone, a personal computer, etc. In the following description, the configuration of a game device will be described as an example of an electronic device.

[0040] The electronic device is a roughly rectangular parallelepiped device equipped with a display unit. In particular, in this embodiment, the electronic device is a portable device that is used while placed on a surface such as a floor or a tabletop, or while held in the user's hand. The electronic device may have functions other than gaming. For example, the electronic device may be a personal computer capable of executing games, such as a portable gaming PC. Furthermore, the game processing is not limited to being executed on the electronic device itself, but may also be executed on a console or cloud separate from the electronic device. In this case, for example, images or videos resulting from execution on the separate console or cloud are displayed on the display unit of the electronic device.

[0041] 1 is a front view schematically illustrating an electronic device according to an embodiment of the present disclosure. As shown in FIG. 1, the electronic device 1 includes a housing 2 and two controllers 3.

[0042] In this specification and the drawings, for convenience of explanation, the thickness direction of the electronic device 1 is called the X direction, the width direction of the electronic device 1 is called the Y direction, and the height direction of the electronic device 1 is called the Z direction. The X direction, Y direction, and Z direction are perpendicular to each other.

[0043] The two controllers 3 shown in FIG. 1 are used to operate the electronic device 1. One user may use at least one of the two controllers 3 to play a game executed on the electronic device 1. Two users may play a game executed on the electronic device 1, with one user using one of the two controllers 3 and the other user using the other of the two controllers 3. A controller other than the two controllers 3 may be used to operate the electronic device 1. In this case, three or more users can play a game executed on the electronic device 1. For example, a first user may use one of the two controllers 3, a second user may use the other of the two controllers 3, and a third user may use the other controller, so that three users can play a game executed on the electronic device 1. The two controllers 3 and the other controller may be capable of remotely operating the electronic device 1 via a network such as the Internet. In this case, multiple users in different locations can play a game executed on the electronic device 1.

[0044] Each of the two controllers 3 includes, for example, a stick 31 and operation buttons 32 for performing operations. Each of the two controllers 3 can be attached to and detached from the housing 2. One of the two controllers 3 can be attached to and detached from a side surface 2A on one side in the Y direction of the housing 2. The other of the two controllers 3 can be attached to and detached from a side surface 2B on the other side in the Y direction of the housing 2. Known means such as fitting, sliding, or magnets can be used to attach and detach the two controllers 3 to and from the housing 2. Note that the electronic device 1 may include only one controller 3 or may not include a controller 3.

[0045] Fig. 2 is a rear view schematically illustrating an electronic device according to an embodiment of the present disclosure, with a portion of the housing omitted to show the interior of the electronic device. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2.

[0046] 2 and 3, the housing 2 has a substantially rectangular parallelepiped shape and has an internal space 2C. The housing 2 includes a first housing 21 (lower housing) and a second housing 22 (upper housing). The first housing 21 and the second housing 22 are combined to form the housing 2. The housing 2 may be formed as a single member by integral molding, or may be formed by combining three or more members.

[0047] The first housing 21 includes a main wall 211 and a side wall 212. The main wall 211 is an example of a wall portion. In FIG. 2 , a portion of the housing 2 that is omitted is the main wall 211. The main wall 211 is a plate-shaped wall that extends in the Y and Z directions. The main wall 211 has a thickness along the X direction. The side wall 212 extends in the X direction from the entire periphery of the outer edge of the main wall 211 when the main wall 211 is viewed along the X direction. The first housing 21 is box-shaped with one side in the X direction that is open.

[0048] As shown in FIG. 3 , the second housing 22 is connected to the side wall 212 of the first housing 21 by known means such as fitting or screwing. The second housing 22 has a recess 22A in a portion excluding the outer edge when viewed along the X direction. The display unit 4 is disposed in the recess 22A of the second housing 22. The display unit 4 is exposed to the outside of the housing 2. This allows images, videos, etc. displayed on the display unit 4 to be viewed from outside the electronic device 1. The electronic device 1 may be capable of displaying images, videos, etc. on an external display such as a television. In this case, for example, the electronic device 1 is provided with an HDMI (High-Definition Multimedia Interface (registered trademark)) terminal, and the electronic device 1 and the external display are connected via an HDMI cable.

[0049] The space surrounded by the housing 2 and the display unit 4 configured as above is the internal space 2C of the housing 2.

[0050] As shown in FIGS. 2 and 3, a battery pack 5, an antenna 6, a circuit board 7, and a cable 8 are provided in an internal space 2C of the housing 2.

[0051] As shown in FIGS. 2 and 3, the battery pack 5 includes a battery 51, a protection circuit 52, a first cover 53, and a cushion 54.

[0052] The battery 51 is a rechargeable battery, such as a lithium ion battery.

[0053] The protection circuit 52 is a circuit for preventing over-discharge, over-charge, over-current, etc. of the battery 51, and has a known structure. In this embodiment, the protection circuit 52 is a board on which various mounted components 521 are mounted. The protection circuit 52 is provided near the battery 51. The protection circuit 52 is electrically connected to the battery 51 and the board 7. The length of the protection circuit 52 in the X direction, which is the thickness direction of the battery pack 5, is shorter than the length of the battery 51 in the X direction. In other words, the thickness of the protection circuit 52 is thinner than the thickness of the battery 51.

[0054] The cushions 54 are arranged to sandwich the protection circuit 52 in the X direction. The cushions 54 are made of a soft material such as sponge and protect the protection circuit 52 from external impacts. The first cover 53 covers the battery 51, the protection circuit 52, and the cushions 54. In this embodiment, the first cover 53 is a film-like material.

[0055] 2, the antenna 6 is a member for transmitting and receiving radio waves, and a known antenna is used. For example, the antenna 6 is used for communication such as Bluetooth (registered trademark) and wireless LAN.

[0056] The substrate 7 comprises a base material made of an insulating material such as glass epoxy or ceramic, a conductive wiring pattern and an electrode pattern provided on at least one of the surface and the interior of the base material, and a plurality of mounted components mounted on the surface of the base material.

[0057] 2 shows a control unit 71 and a connector 72 as mounted components, and does not show other mounted components. In this embodiment, the control unit 71 is an integrated circuit (IC) that controls the operation of the electronic device 1, including the antenna 6.

[0058] In FIG. 2, only a wiring pattern 73 that electrically connects the control unit 71 and the connector 72 is shown as a wiring pattern, and other wiring patterns are omitted.

[0059] 2 shows a ground electrode 74 electrically connected to the ground of the electronic device 1 as an electrode pattern, and other electrode patterns are omitted. An example of another electrode pattern is a ground pattern. The ground pattern is formed by filling in areas on the surface and / or inside of the substrate where no wiring pattern is provided, and functions as the ground of the electronic device 1. The ground electrode 74 is electrically connected to the ground pattern or constitutes part of the ground pattern. Note that the ground electrode 74 may be provided somewhere other than the substrate 7. For example, the second housing 22 described above may be the ground electrode.

[0060] 2, the battery pack 5 is rectangular when viewed along the X direction. When viewed along the X direction, the rectangular battery pack 5 has a long side 5A and a short side 5B. In this embodiment, the long side 5A is aligned along the Z direction, and the short side 5B is aligned along the Y direction.

[0061] The cable 8 connects the antenna 6 and the connector 72. One end of the cable 8 is connected to the antenna 6. The other end of the cable 8 is connected to the connector 72. As described above, the connector 72 and the control unit 71 are electrically connected via the wiring pattern 73. As described above, the cable 8 connects the antenna 6 and the control unit 71.

[0062] 3, the cable 8 is a coaxial cable having a circular cross section. However, the cross-sectional shape of the cable 8 is not limited to a circular shape, and the cable 8 is not limited to a coaxial cable.

[0063] 2 , the antenna 6 is located on one side in the Y direction relative to the battery pack 5, and the connector 72 is located on the other side in the Y direction relative to the battery pack 5. In other words, the battery pack 5 is located between the antenna 6 and the connector 72 in the direction along the short side 5B of the rectangular battery pack 5 (the Y direction in this embodiment).

[0064] The cable 8 is routed from the antenna 6 over the battery pack 5 to the connector 72. The routing of the cable 8 from the antenna 6 to the connector 72 will be described later.

[0065] As shown in FIGS. 2 and 3, an operation button 10 and a flexible printed circuit (FPC) 11 are provided in an internal space 2C of the housing 2.

[0066] The operation button 10 is a button that is pressed by a user to operate the electronic device 1. The operation button 10 is provided alongside the battery pack 5 in a direction along the long side 5A of the rectangular battery pack 5 (the Z direction in this embodiment). The operation button 10 is an example of an electronic component. The electronic component provided alongside the battery pack 5 in the Z direction is not limited to the operation button 10 and may be, for example, an optical sensor.

[0067] In this embodiment, the operation buttons 10 include a power button 101 and volume buttons 102 and 103. The power button 101 and the volume buttons 102 and 103 are electrically connected to the substrate 7 via a flexible printed circuit board 11.

[0068] The power button 101 and the volume buttons 102 and 103 are exposed to the outside of the electronic device 1 through an opening provided on a side surface 2D of the housing 2 that faces the Z direction. This allows the power button 101 and the volume buttons 102 and 103 to be pressed by a user.

[0069] When the power button 101 is pressed while the power of the electronic device 1 is off, the electronic device 1 starts up. When the power button 101 is pressed while the power of the electronic device 1 is on, the electronic device 1 shuts down.

[0070] Pressing the volume button 102 decreases the volume output from a speaker (not shown) built into the electronic device 1. Pressing the volume button 103 increases the volume output from the speaker.

[0071] 2 and 3, a second cover 12 is provided in the internal space 2C of the housing 2. The second cover 12 functions as a shield to suppress the effects of noise generated from components arranged inside the housing 2 (e.g., components mounted on the substrate 7) or external noise that the components arranged inside the housing 2 are subjected to.

[0072] As shown in Fig. 2, the second cover 12 overlaps with the battery pack 5 and the circuit board 7 when viewed along the X direction. As shown in Fig. 3, the battery pack 5 and the circuit board 7 are sandwiched between the second cover 12 and the second housing 22 in the X direction. In other words, the second housing 22 is located on the same side of the second cover 12 as the battery pack 5 in the X direction.

[0073] In the X direction, the second cover 12 is located on the main wall 211 side of the battery pack 5 and the circuit board 7. In the X direction, the second cover 12 is located between the main wall 211 and the battery pack 5 and the circuit board 7. In other words, the main wall 211 is located on the opposite side of the second cover 12 from the battery pack 5 in the X direction. In the X direction, the second cover 12 and the main wall 211 face each other.

[0074] In the X direction, the second housing 22 is located on the display unit 4 side with respect to the battery pack 5 and the board 7. In the X direction, the second housing 22 is located between the display unit 4 and the battery pack 5.

[0075] The second cover 12 may be located in a position overlapping the protection circuit 52 of the battery pack 5 when viewed along the X direction, which is the thickness direction of the battery pack 5. For example, the second cover 12 does not need to overlap the battery 51 when viewed along the X direction.

[0076] The second cover 12 and the second housing 22 are made of metal. However, the second cover 12 and the second housing 22 may be made of a material other than metal, such as resin.

[0077] The second cover 12 is electrically connected to the ground electrode 74. For example, the second cover 12 and the ground electrode 74 are connected to each other via a conductor cable.

[0078] 2 , the portion of the second cover 12 that overlaps with the battery pack 5 when viewed along the X direction is located on the opposite side of the second housing 22 in the X direction from the portion of the second cover 12 that overlaps with the board 7 when viewed along the X direction. The second cover 12 has a step portion 12A at the boundary between the portion that overlaps with the battery pack 5 when viewed along the X direction and the portion that overlaps with the board 7 when viewed along the X direction. Note that the second cover 12 may have another step portion in addition to the step portion 12A, or may not have the step portion 12A.

[0079] The second cover 12 has an opening 12B at a position overlapping the connector 72 when viewed along the X direction, which allows the user to easily access the connector 72. Note that the second cover 12 may have another opening in addition to the opening 12B, or may not have the opening 12B at all.

[0080] As shown in FIG. 3 , the second cover 12 has a curved portion 12C. The curved portion 12C is a portion of the second cover 12 that is bent toward the battery pack 5 in the X direction. The second cover 12 is recessed in the X direction at the curved portion 12C toward the battery pack 5. This recessed portion is a groove 12D. In other words, the groove 12D is provided in the curved portion 12C. The groove 12D is formed by a surface 12Da of the curved portion 12C that faces the main wall 211. In other words, the groove 12D is formed by a surface 12Da that is a part of a surface 12E of the second cover 12 that is on the opposite side from the battery pack 5 in the X direction. Note that the groove 12D is not limited to being formed by the curved portion 12C. For example, the groove 12D may be formed by thinning a portion of the plate-shaped second cover 12.

[0081] 2, the groove 12D is located so as to overlap the protection circuit 52 when viewed along the X direction. Note that only a portion of the groove 12D may be located so as to overlap the protection circuit 52 when viewed along the X direction.

[0082] As shown in FIG. 3, the groove 12D is located between the protection circuit 52 and the main wall 211 in the X direction.

[0083] 2, the groove 12D extends across the rectangular battery pack 5. The groove 12D extends parallel to the short side 5B of the rectangular battery pack 5 (in other words, extends along the Y direction) from one long side 5Aa to the other long side 5Ab of the rectangular battery pack 5. In this embodiment, the groove 12D extends from the end of the second cover 12 on the antenna 6 side in the Y direction to the step portion 12A.

[0084] The groove 12D does not have to be parallel to the short side 5B of the rectangular battery pack 5. For example, the groove 12D may extend in a direction slightly inclined from (in other words, approximately parallel to) the short side 5B of the rectangular battery pack 5. Furthermore, for example, the groove 12D may be curved rather than straight.

[0085] The groove 12D is located on the opposite side of the operation button 10 (electronic component) with respect to a center position C of the battery pack 5 in the Z direction along the long side 5A of the battery pack 5. In other words, the center position C of the battery pack 5 in the Z direction is located between the operation button 10 and the groove 12D. Note that the groove 12D may be located on the same side of the center position C of the battery pack 5 in the Z direction as the operation button 10 (electronic component) in the Z direction.

[0086] The wiring route of the cable 8 from the antenna 6 to the connector 72 will be described below.

[0087] 2, the cable 8 has a first portion 81, a second portion 82, and a third portion 83. The first portion 81 is a portion of the cable 8 that is located between the antenna 6 and the groove portion 12D. The second portion 82 is a portion of the cable 8 that is located in the groove portion 12D. The third portion 83 is a portion of the cable 8 that is located between the groove portion 12D and the control unit 71 (in this embodiment, between the groove portion 12D and the connector 72). The second portion 82, which is a part of the cable 8, is housed in the groove portion 12D.

[0088] The electronic device 1 includes a fastener 91 and a tape 92 for fixing the wiring position of the cable 8 .

[0089] In the present embodiment, the fastening portion 91 is a clip that clamps the cable 8. The clip is formed, for example, by bending a frame disposed in the internal space 2C of the electronic device 1. The fastening portion 91 fixes the wiring position of the cable 8 in at least one of the first portion 81 and the third portion 83. In the present embodiment, the fastening portion 91 is provided at the position where the first portion 81 of the cable 8 is wired, and fixes the position of the first portion 81 of the cable 8. The fastening portion 91 may also be provided at the position where the second portion 82 of the cable 8 is wired, and fix the wiring position of the second portion 82 of the cable 8. The fastening portion 91 may also be provided at the position where the third portion 83 of the cable 8 is wired, and fix the wiring position of the third portion 83 of the cable 8.

[0090] The tape 92 is attached across the cable 8 and portions of the electronic device 1 other than the cable 8 to fix the wiring position of the cable 8. In the present embodiment, the tape 92 fixes the position of the second portion 82 of the cable 8. The tape 92 is attached to the second cover 12 so as to straddle the opening of the groove 12D in the Z direction. This blocks the opening of the groove 12D at the portion where the tape 92 is attached. The tape 92 can also be attached to the second portion 82 of the cable 8 housed in the groove 12D. As described above, the tape 92 fixes the wiring position of the second portion 82 of the cable 8 in the groove 12D. Note that the tape 92 may be attached to the first portion 81 of the cable 8 to fix the wiring position of the first portion 81, or may be attached to the third portion 83 of the cable 8 to fix the wiring position of the third portion 83.

[0091] 3, the depth D of the groove 12D in the X direction is longer than the length R in the X direction of the second portion 82 of the cable 8 housed in the groove 12D (in this embodiment, the diameter R of the second portion 82 of the cable 8). The depth D may be the same as the length R (in other words, the diameter R). In other words, the depth D is equal to or longer than the diameter R.

[0092] The distance G in the X direction between the main wall 211 and the surface 12E of the second cover 12 is shorter than the diameter R of the second portion 82 of the cable 8 housed in the groove portion 12D. Note that the distance G may be equal to or greater than the diameter R.

[0093] In this embodiment, the surface 12Da constituting the groove 12D is smoothly curved. That is, in this embodiment, the surface 12Da does not have a bent portion. The surface 12Da is curved at the innermost portion of the groove 12D with the same or approximately the same curvature as the circular cross section of the second portion 82 of the cable 8, which is a coaxial cable. Note that the surface 12Da may have a bent portion.

[0094] The second housing 22 has a rib 221. The rib 221 protrudes from a surface 22B of the second housing 22 facing the second cover 12 in the X direction toward the second cover 12. The rib 221 extends in the Y direction. In other words, the rib 221 extends parallel to the groove 12D. The rib 221 is located next to the battery pack 5 in the Z direction. The rib 221 faces the curved portion 12C of the second cover 12 in the Z direction and is in contact with the curved portion 12C. The rib 221 may extend in a direction slightly inclined with respect to the groove 12D. In other words, the rib 221 may extend approximately parallel to the groove 12D.

[0095] In this embodiment, the rib 221 of the second housing 22, which is made of metal, is in contact with the second cover 12, which is also made of metal and is electrically connected to the ground electrode 74. In other words, the second housing 22 is electrically connected to the ground electrode 74 via the second cover 12. Note that the second housing 22 does not necessarily have to be electrically connected to the ground electrode 74 via the second cover 12. In this case, the second housing 22 may be electrically connected to the ground electrode 74 via a conductor cable, just like the second cover 12.

[0096] FIG. 4 is a cross-sectional view of a portion of an electronic device according to a modified example, which corresponds to the cross-sectional view taken along line III-III in FIG.

[0097] As shown in FIG. 4 , the depth D of the groove 12D in the X direction may be shorter than the diameter R of the second portion 82 of the cable 8 accommodated in the groove 12D. In this case, a portion of the main wall 211 of the first housing 21 facing the groove 12D in the X direction may have a recess 211A. In the configuration shown in FIG. 4 , the depth D of the groove 12D in the X direction is shorter than the diameter R of the second portion 82 of the cable 8 accommodated in the groove 12D, and a portion of the cable 8 is not accommodated in the groove 12D. However, the portion of the cable 8 that is not accommodated in the groove 12D can be accommodated in the recess 211A. This allows the entire cable 8 to be accommodated by the groove 12D and the recess 211A. This prevents the electronic device 1 from increasing in thickness.
