[0004] For electronic devices that do not have an optical disk drive, it is convenient to attach an external optical disk drive via a cable. However, when attaching an external optical disk drive, users may find the installation process cumbersome or the cable exposed to the outside of the electronic device cumbersome. Therefore, while it is possible to adopt a configuration in which the optical disk drive is attached to the electronic device without a cable, measures are required to prevent noise such as electromagnetic waves that may be generated around the connector.

[0005] Therefore, an object of the present disclosure is to provide a connection structure and an optical disc drive that can suppress the effects of noise.

[0006] The connection structure of the present disclosure is a connection structure that electrically connects an electronic device to an optical disk drive that is attachable to the electronic device, and includes: a first connector terminal provided on the optical disk drive; a second connector terminal provided on the electronic device that is connectable to the first connector terminal; a circuit board that is accommodated in a housing of the electronic device and that mounts the second connector terminal; a ground portion provided on the circuit board; and a conductive member that provides electrical conductivity between the ground portion and a metal portion of the optical disk drive when the first connector terminal and the second connector terminal are connected.

[0007] The optical disk drive according to the present disclosure is an optical disk drive that is detachable from an electronic device, and includes a connector terminal that can be connected to an equipment-side connector terminal mounted on a circuit board of the electronic device, and a conductive member that is electrically connected to a ground portion provided on the circuit board when the connector terminal is connected to the equipment-side connector terminal.

[0013] [Overview of Electronic Device 10] The electronic device 10 is, for example, an entertainment device that functions as a game device or audio-visual device. However, the electronic device is not limited to this, and may also be, for example, a personal computer. The electronic device 10 outputs moving image data generated by executing a game program and video and audio data acquired via a network to a display device such as a television. The electronic device 10 also outputs video and audio data acquired from an optical disc, which is a recording medium inserted into an optical disc drive 20, to the display device.

[0014] The electronic device 10 has a housing 12 that houses a circuit board 11 (see FIGS. 7, 9, 10, etc.). Electronic components such as a CPU (central processing unit) and a GPU (graphics processor unit) may be mounted on the circuit board 11. Although not shown, the housing 12 may also house a cooling fan, heat pipe, heat sink, and the like that cool the electronic components mounted on the circuit board 11.

[0015] [Overview of Optical Disc Drive 20] The optical disc drive 20 is a device that reads information stored on an optical disc using laser light or the like. Optical discs are information recording media such as CDs, DVDs, and Blu-Ray Discs (registered trademark). The optical disc drive 20 is preferably compatible with optical discs with a diameter of, for example, 12 cm.

[0016] As shown in FIG. 5 and other figures, the optical disk drive 20 has a case 21 in which an insertion opening 21b through which an optical disk is inserted is formed. The optical disk drive 20 is configured by accommodating in the case 21 a transport mechanism for transporting the optical disk, a chucking mechanism for fixing the optical disk, and the like. The case 21 is box-shaped and constitutes at least a part of the exterior of the optical disk drive 20. The case 21 may constitute the exterior of the optical disk drive 20 together with a metal lower plate 21U shown in FIG. 6. The lower plate 21U may be fixed directly to the case 21 or indirectly via another member. The case 21 is not limited to being made of a single member, but may be made of a combination of multiple members.

[0017] [Attachment / Detachment Structure] As shown in Fig. 6 and other figures, the optical disk drive 20 has connector terminals 22 (first connector terminals) exposed to the outside at the left rear. The connector terminals 22 are mounted on a circuit board housed in the case 21. As shown in Fig. 4 and other figures, the electronic device 10 has connector terminals 13 (device-side connector terminals, second connector terminals) exposed to the outside at the left rear. The connector terminals 13 are mounted on a circuit board 11 housed in the housing 12. The housing 12 has openings 12f that expose the connector terminals 13 to the outside.

[0018] The connector terminals 22 form at least a part of the exterior of the optical disk drive 20 and are provided so as to protrude downward from a lower plate 21U that forms the lower surface of the optical disk drive 20 .

[0019] The connector terminal 22 is rotatable between a non-connected position where it is not connected to the connector terminal 13 and a connected position where it is connected to the connector terminal 13, when the supported portion formed on the case 21 is supported by the electronic device 10.

[0020] 5, the optical disk drive 20 includes a locking claw 21a, which is a supported portion formed on the case 21. The locking claw 21a is formed at the front end of the case 21. Two locking claws 21a are formed on the case 21, spaced apart in the left-right direction (second width direction). Specifically, the locking claws 21a are formed at the front end of the left part and the front end of the right part of the case 21, respectively.

[0021] The locking claw 21 a includes an extension portion 211 a extending downward and a claw portion 212 a protruding forward from the lower end of the extension portion 211 a. The claw portion 212 a preferably protrudes so that the tip of the protruding portion is positioned forward of the front end of the case 21.

[0022] Further, an elastic portion 212b is provided below the claw portion 212a. As shown in the enlarged cross-sectional view of Fig. 8A, the elastic portion 212b is provided so as to protrude downward from the lower end of the claw portion 212a.

[0023] 4, the electronic device 10 includes a locking hole 12h formed in the housing 12. The locking hole 12h is formed in the front portion of the housing 12. Two locking holes 12h are formed in the housing 12, spaced apart in the left-right direction. Specifically, the locking holes 12h are each formed in the front portion of the housing 12 so as to correspond to the positions of the locking claws 21a of the optical disk drive 20.

[0024] 8A , the electronic device 10 includes an upper contact portion 12a that contacts an upper surface of the claw portion 212a of the locking claw 21a when the locking claw 21a is inserted into the locking hole 12h, and a lower contact portion 12b that contacts a lower surface of the elastic portion 212b provided on the claw portion 212a. In this embodiment, the upper contact portion 12a is a part of the housing 12, and the lower contact portion 12b is a part of an upper shield 111 described below.

[0025] When the optical disk drive 20 is installed in the electronic device 10, the two locking claws 21a are first inserted forward and downward into the two locking holes 12h, respectively. That is, as shown in Fig. 3, the locking claws 21a are inserted into the locking holes 12h with the front of the optical disk drive 20 tilted downward. The locking claws 21a inserted into the locking holes 12h are locked by the upper contact portions 12a.

[0026] From a state in which the locking claw 21a is locked to the upper contact portion 12a, the optical disk drive 20 is rotated relative to the electronic device 10 using the locking claw 21a as a fulcrum, thereby moving the rear portion of the optical disk drive 20 downward. As the rear portion of the optical disk drive 20 moves downward, the elastic portion 212b is sandwiched between the locking claw 212a and the lower contact portion 12b and compressed. Furthermore, as the rear portion of the optical disk drive 20 is moved downward, the optical disk drive 20 is placed on the placement surface 12c of the housing 12 of the electronic device 10.

[0027] 6, the optical disk drive 20 is provided with a guide pin 23a that protrudes downward. The guide pin 23a is provided to guide the movement of the connector terminal 22 when connecting the connector terminal 22 to the connector terminal 13. Therefore, the guide pin 23a is preferably provided at the left rear of the optical disk drive 20, near the connector terminal 22.

[0028] Specifically, the guide pins 23a may be provided on a connector housing 23 that accommodates at least a portion of the connector terminals 22. The connector housing 23 is made of metal and is provided so as to protrude downward from the lower plate 21U as shown in Fig. 6. When the connector terminals 22 are in the connected position, at least a portion of the connector housing 23 is fitted into an opening 12f formed in the housing 12 of the electronic device 10, and is thereby accommodated inside the housing 12.

[0029] 8B , the electronic device 10 has a guide hole H through which the guide pin 23a is inserted. The guide hole H may be formed in at least some of the members housed in the housing 12 of the electronic device 10. 8B and 9 show an example in which the guide hole H is formed in the circuit board 11 and the upper shield 111.

[0030] The guide hole H is preferably formed so that the guide pin 23a is inserted therethrough before the connector terminal 22 is connected to the connector terminal 13. Therefore, the tip of the guide pin 23a in the extension direction is preferably located farther from the lower plate 21U than the tip of the connector terminal 22 protruding from the lower plate 21U placed on the electronic device 10. The inner peripheral surface of the guide hole H preferably has a function of guiding the movement of the guide pin 23a. In this embodiment, the guide pin 23a is cylindrical, and the guide hole H is an opening with a circular planar shape. The guide hole H may be a through hole or a bottomed groove.

[0031] The guide pin 23a is preferably disposed forward of the connector terminal 22. That is, the guide pin 23a is preferably disposed closer to the locking claw 21a in the front-rear direction than the connector terminal 22. The guide pin 23a is also preferably disposed to the left of the connector terminal 22.

[0032] In the optical disk drive 20, when the locking claw 21a is locked to the electronic device 10, the optical disk drive 20 is pushed forward. At this time, if the locking claw 21a is not accurately inserted into the locking hole 12h, the position of the connector terminal 22 relative to the connector terminal 13 will shift forward. If the guide pin 23a were located behind or in the same position as the connector terminal 22 in the front-to-rear direction, the guide pin 23a could accidentally interfere with the connector terminal 13 when connecting the connector terminal 22 to the connector terminal 13. In this embodiment, the guide pin 23a is positioned forward of the connector terminal 22, so that the guide pin 23a will not interfere with the connector terminal 13 even if the position of the connector terminal 22 relative to the connector terminal 13 shifts forward.

[0033] In the detachable structure of the present embodiment described above, the user can easily attach the optical disk drive 20 to the electronic device 10 manually, without using tools. Furthermore, in the detachable structure of the present embodiment, the locking claw 21a is provided at the front of the case 21, and the connector terminal 22 is provided at the rear of the case 21. Because the locking claw 21a, which serves as the pivot point, and the connector terminal 22 are spaced apart in the front-to-rear direction, the angle of the connector terminal 22 relative to the connector terminal 13 when the connector terminal 22 is connected to the connector terminal 13 is small. Furthermore, the provision of the guide pin 23a allows the connector terminal 22 to be accurately aligned with the connector terminal 13. This configuration reduces the load on the connector terminals 22 and 13 when they come into contact with each other.

[0034] Furthermore, in this embodiment, the connector terminals 22 on the optical disk drive 20 side protrude downward, and the connector terminals 13 on the electronic device 10 side are provided in a recess formed in the housing 12. In other words, there are no protruding portions related to the connector connection structure on the mounting surface 12c of the electronic device 10. Therefore, when the optical disk drive 20 is not attached, there are no unnecessary protrusions on the electronic device 10. This prevents the aesthetic appearance of the electronic device 10 from being marred by the connector structure.

[0035] [Shielding Structure] Fig. 9 is a top view showing a circuit board accommodated in a housing of an electronic device as viewed from above. Fig. 10 is a bottom view showing a circuit board accommodated in a housing of an electronic device as viewed from below.

[0036] The electronic device 10 has a shield that covers electronic components such as integrated circuits mounted on the circuit board 11 to block electromagnetic waves (noise) emitted from the electronic components and to block external electromagnetic waves. The shield can, for example, prevent radio waves radiated from an antenna mounted on the circuit board from affecting other electronic components housed in the housing 12 of the electronic device 10, and can prevent the antenna from being affected by radio waves radiated from other electronic components.

[0037] As shown in Fig. 9, the upper shield 111 is provided to cover the upper side of the circuit board 11. As shown in Fig. 10, the lower shield 112 is provided to cover the lower side of the circuit board 11. The upper shield 111 and the lower shield 112 are fixed to the circuit board 11 with a plurality of screws, rivets, etc. The upper shield 111 and the lower shield 112 are made of a conductor (a metal such as iron, aluminum, or stainless steel).

[0038] A ground pattern 11G (see FIG. 9 ) is formed on the upper surface of the circuit board 11. The shaded area in FIG. 9 is the area covered by the upper shield 111 and where the ground pattern 11G is formed. The ground pattern 11G is formed, for example, along the outer periphery of the circuit board 11. An outer periphery 111a of the upper shield 111 is in contact with the ground pattern 11G and functions as a ground portion together with the ground pattern 11G.

[0039] 9 , the connector terminals 13 are provided on the outer periphery of the upper surface of the circuit board 11. An opening 111b surrounding the connector terminals 13 is formed in the left rear portion of the upper shield 111. In other words, the upper shield 111 covers the upper side of the circuit board 11 so as to avoid the connector terminals 13. Therefore, the connector terminals 13 are exposed at the left rear portion of the upper shield 111.

[0040] 6 and other figures, a gasket 40, which is a conductive member, is provided at the lower end of the connector housing 23. The gasket 40 is annular in shape and surrounds the connector terminal 22 when viewed from below. The gasket 40 is preferably provided so as to surround at least one of the connector terminal 22 and the connector terminal 13 when the connector terminal 22 and the connector terminal 13 are connected.

[0041] The gasket 40 is made of a conductive elastic material. The connector housing 23 on which the gasket 40 is provided and the lower plate 21U on which the connector housing 23 is provided are both made of a conductive material such as metal. The connector housing 23 is preferably part of the lower plate 21U. In other words, the lower plate 21U and the connector housing 23 are preferably configured integrally.

[0042] 8B , the gasket 40 is provided so as to contact the ground portion of the electronic device 10 when the connector terminals 22 are in the connected position. Furthermore, when the connector terminals 22 are in the connected position, the gasket 40 is compressed between the ground portion of the electronic device 10 and the connector housing 23. As a result, the connector terminals 13 and 22 are located in an area shielded by the substrate on which they are mounted, the connector housing 23, and the gasket 40.

[0043] When the connector terminals 22 are in the connected position, the gasket 40 is electrically connected to the ground pattern 11G and the upper shield 111. As a result, the ground portion of the electronic device 10 and the connector housing 23 and lower plate 21U of the optical disk drive 20 are electrically integrated.

[0044] The adoption of the above-described shielding structure suppresses the emission of electromagnetic waves through the region where upper shield 111 is not present, i.e., the region where opening 111b exposing connector terminal 13 is formed. Furthermore, connector terminal 13 and connector terminal 22 are suppressed from being affected by electromagnetic waves emitted from electronic components mounted on circuit board 11.

[0045] In the present embodiment, the metal parts that are electrically connected to the ground part of the electronic device 10 via the gasket 40 are the connector housing 23 and the lower plate 21U, but this is not limiting. It is preferable that at least a metal part of the optical disk drive 20 be electrically connected to the ground part of the electronic device 10 via the gasket 40 made of a conductive material.

[0046] Furthermore, in this embodiment, an example has been shown in which the gasket 40 is fixed to the connector housing 23, but this is not limiting, and the gasket 40 may be fixed to the electronic device 10 side.

[0047] [Drive cover 30] Fig. 11 is a perspective view of the drive cover as seen from diagonally below. Fig. 12 is a left side view of the drive cover covering the optical disk drive as seen from the left. Fig. 13 is a left side view of the drive cover in the middle of covering the optical disk drive as seen from the left. Fig. 14 is a cross-sectional view showing a cross section taken along a cutting line passing through the rear locking claw.

[0048] The electronic device unit 1 forms part of the exterior of the electronic device 10 and has a drive cover 30 that covers the optical disk drive 20 attached to the electronic device 10. The drive cover 30 is configured to be detachable from the electronic device 10 manually by the user without using tools or the like.

[0049] The drive cover 30 has a shape that has an accommodation space R that accommodates the optical disk drive 20 when attached to the electronic device 10. The drive cover 30 forms the accommodation space R with a front portion 31, a left portion 32, a right portion 33, and an upper portion 34.

[0050] The upper portion 34 of the drive cover 30 has a shape including a slope that slopes gently downward toward the rear. The left portion 32, the right portion 33, and the upper portion 34 are connected at their lower ends. The left portion 32, the right portion 33, and the front portion 31 are connected at their lower ends. The front portion 31, the left portion 32, the right portion 33, and the upper portion 34 form a substantially rectangular opening.

[0051] Rear locking claws 34a are formed on the rear portion of the upper portion 34 of the drive cover 30. Two rear locking claws 34a are formed spaced apart in the left-right direction. Specifically, the rear locking claws 34a are formed on the left rear portion and the right rear portion of the drive cover 30. As shown in the enlarged cross-sectional view of FIG. 14 , the rear locking claws 34a include a shape that protrudes rearward.

[0052] 14, the housing 12 of the electronic device 10 is formed with a rear locking claw 12d that locks the rear locking claw 34a. The rear locking claw 12d has a shape that protrudes forward. The rear locking claw 12d is preferably formed to be able to bend in the front-to-rear direction by elastic deformation.

[0053] A front locking claw 31a is formed on the front portion 31 of the drive cover 30. Two front locking claws 31a are formed spaced apart in the left-right direction (second width direction). The locking claw 31a is located on the other end of the drive cover 30 in the front-rear direction (first width direction) than the end on which the connector terminals 22 are located.

[0054] An insertion opening 31b for inserting an optical disk is formed in the front part 31 of the drive cover 30. The insertion opening 31b is preferably formed so that the opening overlaps with the insertion opening 21b of the optical disk drive 20 in the vertical and horizontal directions when the drive cover 30 is attached to the electronic device 10.

[0055] 11, a protruding edge 31c is formed on the front portion 31 of the drive cover 30 so as to fit along the insertion opening 31b. The protruding edge 31c protrudes rearward. In other words, the protruding edge 31c protrudes toward the storage space R.

[0056] The front locking claw 31a includes an extension portion 311a extending downward from the protruding edge 31c and a claw portion 312a protruding rearward from the lower end of the extension portion 311a. The front locking claw 31a is locked to the housing 12 by being inserted into a locking hole 12e formed in the front part of the housing 12 of the electronic device 10. Three front locking claws 31a may be provided so as to be locked into the three locking holes 12e shown in FIG. 4, respectively.

[0057] When engaging the front locking claw 31a with the housing 12, it is preferable to displace the front locking claw 31a by bending a portion of the front portion 31 of the drive cover 30 below the protruding edge 31c. By configuring the front locking claw 31a to be able to engage with the housing 12 while deforming a portion of the front portion 31, it is possible to make the shape and size of the front locking claw 31a itself less susceptible to deformation. This improves the durability of the front locking claw 31a. Furthermore, by forming the extension portion 311a of the front locking claw 31a integral with the protruding edge 31c, the strength of the front portion 31 of the drive cover 30 can also be improved.

[0058] Furthermore, it is preferable that the drive cover 30 partially contacts the top surface of the optical disk drive 20 when covering the optical disk drive 20. This allows the optical disk drive 20 to be positioned more reliably in the up-down direction.

[0059] Furthermore, the drive cover 30 may elastically contact the optical disc drive 20 when covering the optical disc drive 20. The portion of the drive cover 30 that contacts the optical disc drive 20 may be a portion of the case 21 of the optical disc drive 20 opposite to the side where the locking claws 21 a are provided in the direction in which the optical disc is inserted.

[0060] In this embodiment, as shown in Fig. 3, the elastic portion 24 is provided at the rear of the case 21. Also, as shown in Fig. 11, the drive cover 30 is provided with a protrusion 34b that comes into contact with the elastic portion 24 when the drive cover 30 is covering the optical disk drive 20.

[0061] With this configuration, the optical disk drive 20 is positioned in the up-down direction at its front by the above-mentioned elastic portions 212b, and at its rear by the elastic portion 24. The optical disk drive 20 is positioned in the up-down direction at three points, the two elastic portions 212b and one elastic portion 24, thereby stabilizing the posture of the optical disk drive 20.

[0062] 11 and other figures, the drive cover 30 may be provided with a positioning portion 35. The positioning portion 35 is a portion that positions the drive cover 30 relative to the electronic device 10 in the front-to-back and left-to-right directions. The electronic device 10 may be formed with a positioning hole into which the positioning portion 35 is inserted when the drive cover 30 is attached to the electronic device 10.

[0063] In this embodiment, the optical disk drive 20 is covered by a drive cover 30 that constitutes part of the exterior of the electronic device 10, thereby preventing the appearance from being impaired compared to an external optical disk drive that is connected via a cable. Furthermore, by providing the drive cover 30, the position of the optical disk drive 20 attached to the electronic device 10 can be made more stable.

[0064] [Others] The portion of the connector terminal 22 that contacts the connector terminal 13 may have a floating structure. Specifically, the portion of the connector terminal 22 that contacts the connector terminal 13 may be elastically displaceable in the front-to-rear direction. With this configuration, even when the connector terminal 22 is connected in an inclined state relative to the connector terminal 13, the connection can be made without applying an excessive load to the connector terminal 22.
