[0014] (First Embodiment) Hereinafter, the first embodiment will be described with reference to FIGS. 1 to 6. In this specification, the components according to the embodiment and the description of the components may be described in a plurality of expressions. The components and their descriptions are examples and are not limited by the expressions in this specification. The components may be specified by different names from those in this specification. Also, the components may be described by expressions different from those in this specification.

[0015] FIG. 1 is a perspective view showing a personal computer (PC) 10 according to the first embodiment. As shown in FIG. 1, the PC 10 is a laptop computer. Note that the PC 10 is not limited to this example and may be other types of PCs.

[0016] The PC 10 is an example of an electronic device. Note that the electronic device is not limited to the PC 10 and may be a tablet computer, a smartphone, a mobile phone, a personal digital assistant (PDA), a game machine, a wearable device, or other electronic devices.

[0017] The PC 10 includes a base 11, a display unit 12, and a hinge 13. Each of the base 11 and the display unit 12 is formed in a substantially rectangular plate shape. The hinge 13 connects the base 11 and the display unit 12 so as to be relatively rotatable with respect to each other.

[0018] As shown in each drawing, in this specification, for convenience, an X-axis, a Y-axis, and a Z-axis are defined. The X-axis, the Y-axis, and the Z-axis are orthogonal to each other. The X-axis is provided along the width of the base 11. The Y-axis is provided along the length (depth) of the base 11. The Z-axis is provided along the thickness of the base 11.

[0019] Furthermore, in this specification, the X direction, Y direction, and Z direction are defined. The X direction is the direction along the X axis, including the +X direction indicated by the arrow of the X axis and the -X direction opposite to the direction of the arrow of the X axis. The Y direction is the direction along the Y axis, including the +Y direction indicated by the arrow of the Y axis and the -Y direction opposite to the direction of the arrow of the Y axis. The Z direction is the direction along the Z axis, including the +Z direction indicated by the arrow of the Z axis and the -Z direction opposite to the direction of the arrow of the Z axis.

[0020] The base 11 has a housing 21, a keyboard 22, and a touch pad 23. The housing 21 is formed in a substantially rectangular parallelepiped box shape. The housing 21 has an upper surface 21a. Note that the expressions indicating directions such as up, down, left, right, front, and back in this embodiment are for convenience based on the posture of the PC 10 in FIG. 1, and do not limit positions, postures, directions, usage modes, and various other conditions.

[0021] The upper surface 21a is formed substantially flat and faces in the substantially +Z direction. The keyboard 22 and the touch pad 23 are provided on the upper surface 21a. The PC 10 receives input operations from the user via the keyboard 22 and the touch pad 23.

[0022] The housing 21 has an upper cover 25 and a lower cover 26. The upper cover 25 and the lower cover 26 are removably coupled to each other, for example, by screws. The upper cover 25 has the upper surface 21a. The lower cover 26 has the bottom surface of the housing 21 located opposite to the upper surface 21a. Note that the housing 21 is not limited to this example.

[0023] The display unit 12 has a housing 31 and a display device 32. The housing 31 is formed in a substantially rectangular parallelepiped box shape. The housing 31 has a front surface 31a. A display opening 31b is provided in the front surface 31a. The display opening 31b is a hole that communicates the inside and outside of the housing 31. Note that the display opening 31b may be covered with a transparent or translucent panel.

[0024] The display device 32 is housed in the housing 31 of the display unit 12. The display device 32 is, for example, a liquid crystal display (LCD) or an organic EL display, and displays an image. The display opening 31b of the housing 31 exposes the display device 32 and enables the image to be visually recognized from the outside.

[0025] The end of the housing 21 of the base 11 in the +Y direction is rotatably connected to the housing 31 of the display unit 12 by a hinge 13. For this reason, the PC 10 can be closed so that the upper surface 21a of the housing 21 and the front surface 31a of the housing 31 face each other, and can be opened so that the display unit 12 rises from the upper surface 21a.

[0026] FIG. 2 is a perspective view showing the inside of the base 11 of the first embodiment. FIG. 3 is a perspective view showing the inside of the base 11 with the shield 44 opened in the first embodiment. FIGS. 2 and 3 show the base 11 in a state where, for example, the lower cover 26 is removed.

[0027] As shown in FIG. 3, the base 11 has a substrate 41, two sockets 42, two dual inline memory modules (DIMMs) 43, a shield 44, and screws 45. The socket 42 is an example of an electronic component.

[0028] The housing 21 of the base 11 houses the substrate 41, the socket 42, the DIMM 43, the shield 44, and the screws 45. Further, the base 11 may further have, for example, a CPU, a ROM, a RAM, a storage such as an HDD or an SSD, a battery, and various components housed in the housing 21.

[0029] The substrate 41 is, for example, a printed circuit board (PCB). Various electronic components such as the socket 42 and a CPU are mounted on the substrate 41. Further, an antenna such as a wireless wide area network (WWAN) antenna is mounted on the substrate 41 of the present embodiment. The PC 10 can communicate with an external device via the antenna.

[0030] FIG. 4 is a cross-sectional view schematically showing a part of the base 11 of the first embodiment. As shown in FIG. 3, the substrate 41 has a first surface 41a, a second surface 41b, and a first edge 41c. The first edge 41c is an example of an edge.

[0031] The first surface 41a is provided substantially flat along the X-Y plane and faces in the substantially -Z direction. A socket 42 is mounted on the first surface 41a. The second surface 41b is located on the opposite side of the first surface 41a. The second surface 41b is provided substantially flat along the X-Y plane and faces in the substantially +Z direction.

[0032] As shown in FIG. 2, the substrate 41 further has a second edge 41d. Each of the first edge 41c and the second edge 41d is a part of the outer edge of the substrate 41. Each of the first edge 41c and the second edge 41d extends in the substantially X direction and faces in the substantially +Y direction. In other words, the first edge 41c and the second edge 41d are provided substantially parallel to each other. The +Y direction is a direction along the first surface 41a and is an example of a first direction.

[0033] The substrate 41 has a main body 50, three first protrusions 51, and two second protrusions 52. The second protrusion 52 is an example of a protrusion. Each of the main body 50, the first protrusion 51, and the second protrusion 52 is a part of the substrate 41 and has a part of the first surface 41a and a part of the second surface 41b.

[0034] The socket 42 is mounted on the first surface 41a of the main body 50 in the vicinity of the first edge 41c. As shown in FIG. 4, the main body 50 has the first edge 41c of the substrate 41. For example, the first edge 41c is provided at the end of the main body 50 in the +Y direction. Note that the first edge 41c is not limited to this example.

[0035] The socket 42 is mounted on the first surface 41a of the main body 50 in the vicinity of the first edge 41c. The three first protrusions 51 and the two second protrusions 52 are provided in the vicinity of the socket 42.

[0036] The three first protrusions 51 and the two second protrusions 52 protrude from the first edge 41c in the substantially +Y direction. As shown in FIG. 2, the first protrusions 51 and the second protrusions 52 are alternately arranged in the X direction with an interval therebetween. For this reason, each of the two second protrusions 52 is positioned between two adjacent ones of the three first protrusions 51.

[0037] The first protrusion 51 has a second edge 41d of the substrate 41. For example, the second edge 41d is provided at the end of the first protrusion 51 in the +Y direction. In the present embodiment, the second edges 41d provided on the three first protrusions 51 are arranged on the extension lines of each other. Note that the second edge 41d is not limited to this example.

[0038] A recess 55 is provided between two adjacent ones of the three first protrusions 51. The recess 55 is a space between two adjacent ones of the three first protrusions 51 and is recessed from the second edge 41d in the substantially -Y direction. In the present embodiment, the first edge 41c forms the bottom of the recess 55.

[0039] Each of the two second protrusions 52 is positioned in a corresponding one of the two recesses 55 and protrudes from the first edge 41c which is the bottom of the recess 55. The width of each of the two second protrusions 52 in the X direction is shorter than the width of each of the three first protrusions 51 in the X direction. The widths of the two second protrusions 52 in the X direction are substantially equal to each other. Note that the widths of the first protrusion 51 and the second protrusion 52 are not limited to this example.

[0040] A slit 56 is provided between an adjacent first protrusion 51 and second protrusion 52. The slit 56 is a space between an adjacent first protrusion 51 and second protrusion 52. By providing the second protrusion 52 in the recess 55, two slits 56 are formed, and one recess 55 includes two slits 56. In the present embodiment, four slits 56 are provided in the substrate 41. The first edge 41c forms not only the bottom of the recess 55 but also the bottom of the slit 56.

[0041] The main body 50 further has a plurality of ground terminals 58. The plurality of ground terminals 58 are, for example, a ground plane on the substrate 41 or are electrically connected to the ground plane on the substrate 41. The plurality of ground terminals 58 are provided, for example, for the frame ground. Note that the ground terminal 58 is not limited to this example.

[0042] The plurality of ground terminals 58 are provided on the first surface 41a. As shown in FIG. 3, the plurality of ground terminals 58 are formed in a frame shape surrounding the two sockets 42 as a whole. A part of the ground terminal 58 is located between the socket 42, the first protrusion 51, and the second protrusion 52. Note that the shape of the ground terminal 58 is not limited to this example.

[0043] An insertion hole 59 is provided in the main body 50. The insertion hole 59 is provided in the main body 50, for example, at a position where one of the plurality of ground terminals 58 is provided. The insertion hole 59 penetrates the main body 50 in the substantially Z direction and opens to the first surface 41a and the second surface 41b.

[0044] As shown in FIG. 4, the upper cover 25 has an upper wall 61, a boss 62, a rear wall 63, and four ribs 64. The rib 64 is an example of a restricting portion. The upper wall 61, the boss 62, the rear wall 63, and the rib 64 are integrally formed of a metal such as an aluminum alloy or a magnesium alloy, for example. Note that the upper wall 61, the boss 62, the rear wall 63, and the rib 64 may be different parts from each other or may be made of other materials. Also, a portion of the upper cover 25 that covers the WWAN antenna is made of, for example, a synthetic resin.

[0045] The upper wall 61 has the upper surface 21a of the housing 21, and the keyboard 22 and the touch pad 23 are attached thereto. The upper wall 61 has an inner surface 61a. The inner surface 61a is provided on the side opposite to the upper surface 21a and faces the inside of the housing 21. The inner surface 61a faces the second surface 41b of the substrate 41, for example, with an interval therebetween.

[0046] The boss 62 protrudes from the inner surface 61a of the upper wall 61. The boss 62 is formed, for example, in a substantially cylindrical shape. A screw hole 62a is provided inside the boss 62. A female screw is formed on the inner surface of the screw hole 62a. The screw hole 62a communicates with the insertion hole 59 of the substrate 41.

[0047] The rear wall 63 extends in the substantially -Z direction from the end of the upper wall 61 in the +Y direction. The rear wall 63 extends so as to cross the substrate 41 in the Z direction and covers the first edge 41c and the second edge 41d of the substrate 41. Note that the length of the rear wall 63 in the Z direction may be shorter than the distance between the upper wall 61 and the substrate 41.

[0048] Each of the four ribs 64 is connected to the upper wall 61 and the rear wall 63. In other words, each of the four ribs 64 protrudes from the upper wall 61 and the rear wall 63. As shown in FIG. 2, each of the four ribs 64 is inserted into a corresponding one of the four slits 56. For this reason, each of the plurality of ribs 64 is closer to the first edge 41c than the ends of the first protrusion 51 and the second protrusion 52 in the +Y direction. The end of the first protrusion 51 in the +Y direction is the second edge 41d. Also, the first edge 41c faces the rib 64 with an interval therebetween. The plurality of ribs 64 are spaced apart from the first edge 41c. Also, the plurality of ribs 64 are spaced apart from the first protrusion 51 and the second protrusion 52.

[0049] As shown in FIG. 3, the socket 42 is an electronic component to which the DIMM 43 is attached. An insertion port 42a is provided in each of the two sockets 42. When the DIMM 43 is inserted into the insertion port 42a, the socket 42 electrically connects the DIMM 43 and the substrate 41 to each other.

[0050] The DIMM 43 has, for example, a PCB and a plurality of DRAMs mounted on the PCB. The DIMM 43 is electrically connected to the substrate 41 via the socket 42 when the terminals of the DIMM 43 are inserted into the insertion port 42a of the socket 42.

[0051] In the body embodiment, each insertion port 42a of the two sockets 42 faces in the +X direction or the -X direction. For this reason, each of the two DIMMs 43 is inserted into and removed from the corresponding socket 42 in the X direction. For example, one DIMM 43 is inserted into one socket 42 in the +X direction and removed from the socket 42 in the -X direction. The other DIMM 43 is inserted into the other socket 42 in the -X direction and removed from the socket 42 in the +X direction.

[0052] In the direction along the first surface 41a, each insertion port 42a of the two sockets 42 opens in a direction different from the direction from the socket 42 toward the first edge 41c. That is, each insertion port 42a of the two sockets 42 may face in the X direction or the -Y direction as described above. On the other hand, in the present embodiment, each of the two sockets 42 is not arranged such that the insertion port 42a faces in the +Y direction. Note that the direction in which the insertion port 42a faces is not limited to this example.

[0053] FIG. 5 is a perspective view showing the shield 44 of the first embodiment. The shield 44 is made of a metal such as aluminum or stainless steel and has conductivity. The shield 44 is formed of, for example, an injection-molded metal plate. Note that the shield 44 may be formed by other methods. The shield 44 has a cover 71, two hooks 72, and a mounting portion 73. The cover 71, the hooks 72, and the mounting portion 73 are provided integrally.

[0054] The cover 71 covers the two sockets 42 and the two DIMMs 43. The cover 71 may further cover other components. As shown in FIG. 3, the cover 71 has an upper wall 81, a rear wall 82, a front wall 83, and two side walls 84.

[0055] As shown in FIG. 5, the upper wall 81 is formed in a substantially rectangular plate shape along the X-Y plane. As shown in FIG. 4, the upper wall 81 has an inner surface 81a. The inner surface 81a and the first surface 41a of the substrate 41 face each other with a gap therebetween. Further, the inner surface 81a faces the two sockets 42 and the two DIMMs 43.

[0056] The rear wall 82 extends in a substantially +Z direction from the edge of the upper wall 81 in the +Y direction. The front wall 83 extends in a substantially +Z direction from the edge of the upper wall 81 in the -Y direction. Each of the two side walls 84 extends in a substantially +Z direction from the edge of the upper wall 81 in the X direction. The two side walls 84 are connected to the front wall 83. One of the side walls 84 is connected to the rear wall 82. The ends of the rear wall 82, the front wall 83, and the side walls 84 in the +Z direction abut, for example, against the ground terminal 58.

[0057] FIG. 6 is a perspective view showing the hook 72 of the first embodiment. The two hooks 72 have substantially the same shape as each other. Note that the two hooks 72 may have different shapes from each other. As shown in FIG. 6, each of the two hooks 72 is formed in a substantially L shape and has a first portion 91 and a second portion 92.

[0058] The first portion 91 is formed in a substantially rectangular plate shape along the X-Y plane approximately. The first portion 91 extends, for example, in a substantially +Y direction from the rear wall 82 of the cover 71. For this reason, the hook 72 is provided at the end of the cover 71 in the +Y direction.

[0059] As shown in FIG. 4, the first portion 91 has an inner surface 91a and an outer surface 91b. The inner surface 91a is formed substantially flat and faces in a substantially +Z direction. The outer surface 91b is located on the opposite side of the inner surface 91a. The outer surface 91b is formed substantially flat and faces in a substantially -Z direction.

[0060] The second portion 92 is formed in a substantially rectangular plate shape along the X-Z plane approximately. The second portion 92 extends, for example, in a substantially +Z direction from the end of the first portion 91 in the +Y direction. The second portion 92 has an inner surface 92a and an outer surface 92b. The inner surface 92a is formed substantially flat and faces in a substantially -Y direction. The outer surface 92b is located on the opposite side of the inner surface 92a. The outer surface 92b is formed substantially flat and faces in a substantially +Y direction.

[0061] As shown in FIG. 6, each of the two hooks 72 is provided with a hole 93. The hole 93 penetrates through the first portion 91 and the second portion 92 and opens to the inner surface 91a and outer surface 91b of the first portion 91 and the inner surface 92a and outer surface 92b of the second portion 92. The hole 93 is spaced apart from the end of the second portion 92 in the +Z direction.

[0062] As shown in FIG. 4, each of the two second protrusions 52 extends through a corresponding one of the holes 93 in the two hooks 72. Accordingly, the two hooks 72 are directly hooked on the two second protrusions 52 of the substrate 41.

[0063] When the hook 72 is hooked on the substrate 41, the inner surface 91a of the first portion 91 faces, for example, the first surface 41a of the main body 50. Further, the inner surface 92a of the second portion 92 faces, for example, the first edge 41c. The inner surface 92a is in contact with the first edge 41c. Note that the inner surface 92a may be spaced apart from the first edge 41c. The edge 93a of the hole 93 included in the second portion 92 is in contact with the second surface 41b of the second protrusion 52.

[0064] A part of the second portion 92 of the hook 72 is located between the first edge 41c of the substrate 41 and the rib 64. For this reason, the outer surface 92b of the second portion 92 faces, for example, the rear wall 63 and the rib 64 of the housing 21. The outer surface 92b is spaced apart from the rear wall 63 and the rib 64.

[0065] In another expression, as shown in FIG. 6, each of the two hooks 72 has a first end portion 94, a second end portion 95, and two pillar portions 96. The first end portion 94 is included in the first portion 91 and extends substantially in the +Y direction from the rear wall 82. The second end portion 95 is included in the second portion 92.

[0066] The two pillar portions 96 extend between the first end portion 94 and the second end portion 95 through the slit 56. In other words, one end of the pillar portion 96 is connected to the first end portion 94, and the other end of the pillar portion 96 is connected to the second end portion 95. The two pillar portions 96 are included in the first portion 91 and the second portion 92. A hole 93 is provided between the two pillar portions 96.

[0067] The second end portion 95 extends substantially in the X direction from the end of the pillar portion 96 in the +Z direction and connects the ends of the two pillar portions 96 in the +Z direction. The second end portion 95 abuts against the second surface 41b of the second protrusion 52.

[0068] The shield 44 further has a plurality of abutting portions 98. Each of the plurality of abutting portions 98 is a substantially frustum-shaped protrusion protruding from the inner surface 91a of the first portion 91 (the first end portion 94) of the hook 72. Note that the abutting portion 98 is not limited to this example.

[0069] As shown in FIG. 4, each of the plurality of abutting portions 98 protrudes from the inner surface 91a toward the ground terminal 58 of the substrate 41 and abuts against the ground terminal 58. For this reason, the inner surface 91a is spaced apart from the first surface 41a of the substrate 41.

[0070] As shown in FIG. 2, the mounting portion 73 is formed in a plate shape along the X-Y plane. The mounting portion 73 extends, for example, substantially in the -Y direction from the front wall 83 of the cover 71. For this reason, the mounting portion 73 is provided at the end of the cover 71 in the -Y direction and is spaced apart from the two hooks 72. Note that the mounting portion 73 may extend from another portion of the cover 71 such as the side wall 84.

[0071] As shown in FIG. 4, an insertion hole 73a is provided in the mounting portion 73. The insertion hole 73a penetrates the mounting portion 73 in the substantially Z direction and communicates with the insertion hole 59 of the substrate 41. The screw 45 is inserted into the screw hole 62a of the boss 62 through the insertion hole 73a of the mounting portion 73 and the insertion hole 59 of the substrate 41. Thereby, the mounting portion 73 is detachably attached to the substrate 41 by the screw 45. Note that the mounting portion 73 is not limited to this example, and may be detachably attached to the substrate 41 by other means such as claws.

[0072] The mounting portion 73 abuts against the ground terminal 58. Further, the mounting portion 73 may be electrically connected to the ground terminal 58 and the upper cover 25 of the housing 21 via the screw 45.

[0073] The hook 72 is hooked on the second protrusion 52 of the substrate 41 so that the shield 44 can rotate between the closed position Pc shown in FIG. 2 and the open position Po shown in FIG. 3. In other words, the shield 44 can rotate between the closed position Pc and the open position Po with the second protrusion 52 as a fulcrum. The closed position Pc is an example of the first position. The open position Po is an example of the second position.

[0074] Normally, the shield 44 is located at the closed position Pc shown in FIG. 2. Therefore, the above description regarding the shield 44 describes the shield 44 located at the closed position Pc. As shown in FIG. 2, in the closed position Pc, the cover 71 covers the two sockets 42 and the two DIMMs 43. Therefore, the shield 44 can shield the electromagnetic waves emitted from the DIMM 43 and suppress, for example, the input of noise caused by the electromagnetic waves to the WWAN antenna. Also, in the closed position Pc, the mounting portion 73 is arranged such that the insertion hole 73a communicates with the insertion hole 59 of the substrate 41, and is attached to the substrate 41 by the screw 45.

[0075] Furthermore, as shown in FIG. 4, at the closed position Pc, the edge 93a (second end portion 95) of the hole 93 of the hook 72 abuts against the second surface 41b of the second protrusion 52. By the edge 93a (second end portion 95) of the hole 93 of the hook 72 abutting against the second surface 41b of the second protrusion 52, the removal of the hook 72 from the substrate 41 in the -Z direction is restricted.

[0076] Furthermore, at the closed position Pc, the contact portion 98 abuts against the ground terminal 58. Thereby, the shield 44 is electrically connected to the ground terminal 58. Also, in the Z direction, the distance between the end of the contact portion 98 in the +Z direction and the edge 93a (second end portion 95) of the hole 93 of the hook 72 is shorter than the thickness of the substrate 41. For this reason, the shield 44 is elastically deformed so that the contact portion 98 is pressed against the ground terminal 58, is hooked on the second protrusion 52 of the substrate 41 at the hook 72, and is attached to the substrate 41 by the attachment portion 73.

[0077] The shield 44 is rotatable with respect to the substrate 41 about a rotation axis extending substantially in the X direction. As shown in FIG. 3, at the open position Po, the cover 71 is spaced apart from the socket 42 and the DIMM 43 more than at the closed position Pc. Also, at the open position Po, the front wall 83 of the shield 44 is spaced apart from the substrate 41 more than at the closed position Pc.

[0078] When the shield 44 rotates from the closed position Pc to the open position Po, the front wall 83 and the attachment portion 73 provided at the end of the cover 71 in the -Y direction are spaced apart from the substrate 41. The -Y direction is an example of the second direction. When the shield 44 is located at the closed position Pc, the attachment portion 73 is attached to the substrate 41 by the screw 45, thereby restricting the rotation of the shield 44. Note that the shield 44 may be rotatable in other directions.

[0079] Even at the open position Po, the edge 93a (second end portion 95) of the hole 93 of the hook 72 abuts against the second surface 41b of the second protrusion 52. Alternatively, instead of the edge 93a abutting against the second protrusion 52, the second portion 92 of the hook 72 may abut against the second surface 41b of the main body 50. Thereby, the hook 72 is restricted from being removed from the substrate 41 in the -Z direction.

[0080] The hole 93 of the hook 72 is provided not only in the second portion 92 but also in the first portion 91. For this reason, the shield 44 can be rotated to a position where the first portion 91 extends substantially in the Z direction and the second protrusion 52 extends through the portion of the hole 93 provided in the first portion 91.

[0081] At the open position Po, the screw 45 is removed from the shield 44. For this reason, the shield 44 can be slightly moved in the Y direction with respect to the substrate 41. However, the rib 64 abuts against a part (column portion 96) of the hook 72, thereby restricting the second protrusion 52 from coming out of the hole 93 of the hook 72.

[0082] The distance between the end of the second protrusion 52 in the +Y direction and the rear wall 63 of the upper cover 25 may be shorter than the thickness of the hook 72. In this case, even if the rib 64 is omitted, the second protrusion 52 can be suppressed from coming out of the hole 93 of the hook 72.

[0083] The shield 44 exposes the two sockets 42 and the two DIMMs 43 at the open position Po. For this reason, when the shield 44 is located at the open position Po, the user can perform the insertion / removal operation of the DIMM 43 with respect to the socket 42.

[0084] The insertion port 42a of the socket 42 does not face the shield 44 located at the open position Po. For this reason, in the insertion / removal operation of the DIMM 43 with respect to the socket 42, the DIMM 43 is suppressed from interfering with the shield 44.

[0085] For example, when the user replaces the DIMM 43, first the lower cover 26 of the housing 21 is removed from the upper cover 25. As a result, the substrate 41 and the shield 44 are exposed. At this time, since the shield 44 is located at the closed position Pc, the two sockets 42 and the two DIMMs 43 are covered by the shield 44.

[0086] Next, the user removes the screw 45 from the upper cover 25, the substrate 41, and the shield 44. As a result, the shield 44 becomes rotatable from the closed position Pc to the open position Po. The user rotates the shield 44 from the closed position Pc to the open position Po to expose the two sockets 42 and the two DIMMs 43.

[0087] The user removes the exposed DIMM 43 from the socket 42 and inserts a new DIMM 43 into the insertion port 42a of the socket 42. Next, the user rotates the shield 44 at the open position Po to the closed position Pc and attaches the shield 44 to the substrate 41 with the screw 45. Next, the user attaches the lower cover 26 to the upper cover 25 to complete the replacement work of the DIMM 43. As described above, the user can replace the DIMM 43 with a simple procedure.

[0088] In the PC 10 according to the first embodiment described above, the conductive shield 44 has a cover 71 and a hook 72 provided integrally with the cover 71. The hook 72 is hooked on the substrate 41 so that the shield 44 can rotate between a closed position Pc where the cover 71 covers the socket 42 and an open position Po where the cover 71 is separated from the socket 42 more than the closed position Pc. That is, the shield 44 can be attached to the substrate 41 so as to be openable and closable without passing through other parts such as clips and hinges. Thereby, the PC 10 can easily open and close the shield 44 without performing attachment and detachment operations with other parts such as clips and hinges, and can facilitate operations on the socket 42 and the DIMM 43 shielded from electromagnetic waves by the shield 44. For example, the PC 10 can facilitate the replacement of the DIMM 43. Further, since the PC 10 does not require other parts such as clips and hinges, the cost can be reduced.

[0089] For example, conventionally, a shield may be attached to a substrate via a part such as a clip. In this case, once the user removes the shield from the clip, it may be difficult to attach the shield to the clip again. However, in the PC 10 of the present embodiment, the shield 44 can be attached to the substrate 41 without passing through other parts such as clips. Therefore, the PC 10 can easily open and close the shield 44 without performing attachment and detachment operations with other parts such as clips, and can facilitate operations on the socket 42 and the DIMM 43.

[0090] In addition, since the shield 44 can simplify the structure for fixing the shield 44 to the substrate 41, the cost can be reduced and the degree of freedom in mounting on the substrate 41 can be improved. Further, since the PC 10 can cover the socket 42 and the DIMM 43 with the shield 44 having a simplified structure for fixing while being a metal plate, for example, the electromagnetic wave shielding performance by the shield 44 can be made higher than that of an electromagnetic wave absorption sheet, and the performance of the DIMM 43 can be stabilized.

[0091] The substrate 41 has a first surface 41a on which the socket 42 is mounted, a second surface 41b on the opposite side of the first surface 41a, a first edge 41c facing in the +Y direction along the first surface 41a, and a second protrusion 52 protruding from the first edge 41c. A hole 93 through which the second protrusion 52 passes is provided in the hook 72. The hook 72 abuts against the second protrusion 52 or the second surface 41b to restrict the hook 72 from being removed from the substrate 41 in the -Z direction in which the first surface 41a faces. Thereby, the PC 10 can suppress the shield 44 from undesirably dropping off the substrate 41.

[0092] The shield 44 has a mounting portion 73 provided integrally with the cover 71 at a position spaced apart from the hook 72. The mounting portion 73 is removably attached to the substrate 41 to restrict the rotation of the shield 44. Thereby, the PC 10 can suppress the shield 44 from opening inadvertently and can surely shield the electromagnetic waves emitted by the socket 42 and the DIMM 43.

[0093] The hook 72 is provided at the end of the cover 71 in the +Y direction. When the shield 44 rotates from the closed position Pc to the open position Po, the end of the cover 71 in the -Y direction opposite to the +Y direction moves away from the substrate 41. That is, the shield 44 rotates about a rotation axis substantially parallel to the first surface 41a. Thereby, the PC 10 can suppress the rotating shield 44 from interfering with the components mounted on the first surface 41a as compared with the case where the shield 44 rotates about a rotation axis orthogonal to the first surface 41a.

[0094] The substrate 41 has a ground terminal 58 provided on the first surface 41a. The shield 44 has a contact portion 98. The contact portion 98 protrudes from the hook 72 and contacts the ground terminal 58. The shield 44 is hooked on the substrate 41 at the hook 72 and attached to the substrate 41 at the mounting portion 73 in a state of being elastically deformed so that the contact portion 98 is pressed against the ground terminal 58. Thereby, the shield 44 can surely secure a ground connection.

[0095] The housing 21 has a rib 64 closer to the substrate 41 than the end of the second protrusion 52 in the +Y direction. The first edge 41c faces the rib 64. At least a part of the hook 72 is located between the first edge 41c and the rib 64. Thereby, the rib 64 abuts against the hook 72 to limit the movement of the hook 72 in the +Y direction. Therefore, the rib 64 can prevent the second protrusion 52 from coming out of the hole 93 of the hook 72, and thus prevent the shield 44 from falling off the substrate 41 undesirably. The PC 10 can prevent the shield 44 from being lost by suppressing the detachment of the shield 44.

[0096] (Second Embodiment) Hereinafter, the second embodiment will be described with reference to FIG. 7. In the description of the following plurality of embodiments, components having the same functions as the components already described may be denoted by the same reference numerals as those of the already described components, and the description may be further omitted. In addition, a plurality of components denoted by the same reference numerals do not necessarily have all the same functions and properties, and may have different functions and properties according to each embodiment.

[0097] FIG. 7 is a perspective view showing a part inside the base 11 according to the second embodiment. As shown in FIG. 7, the shield 44 of the second embodiment has a plurality of contact portions 298 instead of the plurality of contact portions 98. The contact portion 298 is substantially equal to the contact portion 98 except for the points described below.

[0098] The contact portion 298 is formed by, for example, bending the shield 44. The contact portion 298 is provided between the end of the rear wall 82 in the +Z direction and the first portion 91, and protrudes from the inner surface 91a of the first portion 91. The contact portion 298 extends substantially in the X direction. Note that the contact portion 298 may be provided on other parts of the hook 72.

[0099] As in the first and second embodiments described above, the contact portions 98, 298 may be formed in various shapes such as a substantially frustum-shaped protrusion or a protrusion extending in a substantially X direction formed by bending. The shape of the contact portion is not limited to the shape of the contact portions 98, 298, and other shapes may be used.

[0100] (Third Embodiment) Hereinafter, the third embodiment will be described with reference to FIG. 8. FIG. 8 is a perspective view showing a part of the base 11 according to the third embodiment. As shown in FIG. 8, the base 11 of the third embodiment has a substrate 341 instead of the substrate 41. The substrate 341 is substantially equal to the substrate 41 except for the points described below. The substrate 341 has a main body 50 and three first protrusions 51, but the second protrusion 52 is omitted. For this reason, a recess 55 is provided in the substrate 341, but the slit 56 is not provided.

[0101] The shield 44 of the third embodiment has two hooks 372 instead of the two hooks 72. Each of the two hooks 372 has a first portion 391, a second portion 392, and two claws 393. The hook 372, the first portion 391, and the second portion 392 are substantially equal to the hook 72, the first portion 91, and the second portion 92 except for the points described below.

[0102] In the closed position Pc, the second portion 392 of each of the two hooks 372 extends through a corresponding one of the two recesses 55 in the substrate 341. The two claws 393 protrude in the X direction from the end of the second portion 392 in the +Z direction.

[0103] In the closed position Pc, the claws 393 of the hook 372 contact the second surface 41b of the first protrusion 51. Therefore, the two hooks 372 are hooked on the substrate 41. The claws 393 contact the second surface 41b of the first protrusion 51 to limit the hook 372 from being removed from the substrate 41 in the -Z direction.

[0104] In the Z direction, the distance between the end of the contact portion 98 in the +Z direction and the claw 393 is shorter than the thickness of the substrate 341. Therefore, the shield 44 is hooked on the second protrusion 52 of the substrate 41 at the hook 372 and attached to the substrate 341 at the attachment portion 73 in a state of being elastically deformed so that the contact portion 98 is pressed against the ground terminal 58.

[0105] In the open position Po, each first portion 391 of the two hooks 372 extends through a corresponding one of the two recesses 55 of the substrate 341. Further, in the open position Po, the second portion 392 abuts against the second surface 41b of the main body 50. Thereby, the hook 372 is restricted from being removed from the substrate 41 in the -Z direction.

[0106] In the open position Po, a part of the first portion 391 is located between the first edge 41c of the substrate 41 and the rib 64. Therefore, the rib 64 restricts the hook 372 from coming out of the recess 55 of the substrate 341 by abutting against a part of the first portion 391 of the hook 372.

[0107] As in the first to third embodiments described above, the hooks 72, 372 may be hooked on the substrate 41 by passing the second protrusion 52 of the substrate 41 through the hole 93 provided in the hook 72, or the hook 372 may be hooked on the substrate 341 by passing through the recess 55 provided in the substrate 341. The method of hooking the hook to the substrate is not limited to the method of hooking the hooks 72, 372 to the substrates 41, 341, and other methods may be used.

[0108] In the above-described plurality of embodiments, the socket 42 is an example of an electronic component. However, the electronic component may be various components included in a power supply circuit or other electronic components such as an SSD. The shield may cover an electronic component that emits electromagnetic waves that can cause noise, such as a DIMM 43 or an SSD, or may cover an electronic component to be protected from electromagnetic waves, or may cover various other electronic components.

[0109] In the above description, suppression is defined as, for example, preventing the occurrence of an event, action, or influence, or reducing the degree of an event, action, or influence. Further, in the above description, restriction is defined as, for example, preventing movement or rotation, or allowing movement or rotation within a predetermined range and preventing movement or rotation exceeding the predetermined range.

[0110] The above-described embodiments of the present invention do not limit the scope of the invention and are merely examples included in the scope of the invention. Certain embodiments of the present invention may be modified, omitted, and added in a range not departing from the gist of the invention, for example, with respect to at least a part of specific uses, structures, shapes, actions, and effects, compared to the above-described embodiments.
