Summary of the Invention
Problems to be Solved by the Invention
[0004] The camera module needs to be shielded with a member having electromagnetic wave shielding properties, such as an aluminum sheet, for electrostatic countermeasures and noise countermeasures. In particular, in the camera module, shielding of the connector to which wiring (for example, a flexible substrate) from the motherboard or the like is connected is important. For example, this is to prevent static electricity from being transmitted from the connector to the wiring and damaging the motherboard or the CPU or the like mounted thereon.
[0005] By the way, there is a great demand for miniaturization and thinning of the housing for the above-described electronic devices, and the installation space for the camera module in the housing is limited. For this reason, in addition to the connector, components such as lenses and various signal processing components are densely mounted on the substrate of the camera module. As a result, when covering the connector with an aluminum sheet, for example, other components adjacent to the connector may get in the way, and there is a concern that a gap may be generated between the aluminum sheet and the connector. This gap becomes a problem in terms of electrostatic countermeasures and noise countermeasures for the connector.
[0006] The present invention has been made in consideration of the above-described problems of the prior art, and an object thereof is to provide an electronic device capable of ensuring shielding performance in a camera module.
Means for Solving the Problems
[0007] An electronic device according to an aspect of the present invention is an electronic device equipped with a camera module, wherein the camera module includes a substrate, a connector portion mounted on the substrate, and a component that is mounted on the substrate, adjacent to the connector portion with a gap therebetween, and a step is formed between its surface and the surface of the connector portion. The electronic device further includes a sheet-like member for electromagnetic shielding provided so as to cover from the surface of the connector portion across the gap to the surface of the component, and the sheet-like member has a hole portion at a position overlapping the gap vertically.
Effects of the Invention
[0008] According to the above aspect of the present invention, shielding performance in a camera module can be ensured.

Embodiments for Carrying Out the Invention
[0010] Hereinafter, preferred embodiments of the electronic device according to the present invention will be given and described in detail with reference to the accompanying drawings.
[0011] FIG. 1 is a schematic plan view of an electronic device 10 according to an embodiment as viewed from above. As shown in FIG. 1, the electronic device 10 of the present embodiment is a clamshell-type notebook PC, and has a configuration in which a first housing 11 and a second housing 12 are relatively rotatably connected by a hinge 14. In the present embodiment, the electronic device 10 of the notebook PC is illustrated, but the electronic device may be other than the notebook PC, for example, a tablet PC, a display device, a smartphone, or a portable game machine.
[0012] The second housing 12 is a flat box body and is adjacent to the first housing 11. Inside the second housing 12, various electronic components such as a motherboard 15 on which a CPU and the like are mounted, a storage device, and a battery device are accommodated. A keyboard 16 and a touch pad 17 face the upper surface of the second housing 12.
[0013] The first housing 11 is a flat box body thinner than the second housing 12. The first housing 11 mounts a display panel 18. Hereinafter, with respect to the first housing 11 and each component mounted thereon, based on the direction seen from an operator who visually recognizes the display surface 18a of the display panel 18, the width direction will be referred to as the X1 and X2 directions, the height direction will be referred to as the Y1 and Y2 directions, and the thickness direction will be referred to as the Z1 and Z2 directions for explanation. The X1 and X2 directions may be collectively referred to as the X direction, and the Y1 and Y2 directions and the Z1 and Z2 directions may similarly be referred to as the Y direction and the Z direction.
[0014] The display surface 18a of the display panel 18 faces the Z1-side surface (front surface 11a) of the first housing 11. The first housing 11 includes a housing member 20 that forms a back surface 11b (Z2-side surface) and side surfaces 11c on the four sides, and a bezel member 21 that forms the peripheral edge of the front surface 11a. The bezel member 21 is a thin plate-shaped frame that surrounds the outer peripheral edge of the display panel 18. The front surface 11a of the first housing 11 is covered with a touch glass 22 over substantially the entire surface including the bezel member 21. The hinge 14 is connected to the Y2-side edge of the first housing 11.
[0015] The display panel 18 is composed of, for example, a liquid crystal display or an organic EL display. The display panel 18 has a structure in which, for example, glass, a liquid crystal layer, a light guide plate, etc. are laminated and the outer peripheral edges of the respective layers are fixed to each other with a double-sided tape, an adhesive, or the like. The touch glass 22 covers the display surface 18a to constitute a touch panel that receives touch operations on the display panel 18.
[0016] FIG. 2 is a plan view schematically showing the internal structure of the first housing 11. In FIG. 2, the touch glass 22 and the bezel member 21 are omitted, and only the outer shape of the display panel 18 is shown by a two-dot chain line.
[0017] As shown in FIG. 2, the housing member 20 has a plate portion 24 and a standing wall 25 provided so as to stand up from the outer peripheral edge of the plate portion 24. The plate portion 24 is a rectangular plate and forms the back surface 11b of the first housing 11. The plate portion 24 is, for example, a flat plate or a shallow dome-shaped plate that is slightly curved on the back surface 11b side. The standing wall 25 is a wall portion that stands up in the Z1 direction from the outer peripheral edge of the plate portion 24 and forms each side surface 11c of the first housing 11. The Z1-side surface (upper end surface 25b) of the standing wall 25 serves as the adhering surface of the bezel member 21 (see FIG. 6). The reference numeral 20a in FIGS. 1 and 2 is a protruding portion that projects in the Y1 direction from substantially the center of the Y1-side edge of the housing member 20. The protruding portion 20a expands the installation space for the camera module 34 described later. The protruding portion 20a may be omitted.
[0018] The housing member 20 is configured by joining, by injection molding, a resin frame that forms a standing wall 25 to the edge of a plate portion 24 that is, for example, a laminated plate of carbon fiber reinforced resin. The housing member 20 may also be configured by integrally molding the plate portion 24 and the standing wall 25 with the same metal material, resin material, or the like.
[0019] As shown in FIG. 2, inside the housing member 20, a double-sided adhesive tape 26, a bracket 28, a conductive sheet 30, a wiring portion 32, a camera module 34, and a microphone module 36 are attached.
[0020] For example, a pair of double-sided adhesive tapes 26 are provided on the left and right, and are strip-shaped tapes extending in the Y direction. The double-sided adhesive tape 26 is for fixing the display panel 18 to the housing member 20. The double-sided adhesive tape 26 adhesively fixes the back surface of the display panel 18, which is opposite to the display surface 18a, and the inner surface 24a of the plate portion 24 (the surface on the back side of the back surface 11b).
[0021] For example, a pair of brackets 28 are provided on the left and right along the Y2 side edge of the first housing 11, and are adhesively fixed to the inner surface 24a respectively. The bracket 28 is a metal part for screwing the hinge 14. The bracket 28 is electrically connected to the second housing 12 via a metal hinge 14.
[0022] The conductive sheet 30 is a thin single-sided adhesive sheet formed of a material having high conductivity such as aluminum or copper. The conductive sheet 30 of the present embodiment is an aluminum sheet (aluminum tape). The conductive sheet 30 is attached to the inner surface 24a of the plate portion 24. The conductive sheet 30 can be used for the frame ground of the display panel 18, the camera module 34, and the microphone module 36, and is electrically connected to the second housing 12 via the bracket 28.
[0023] FIG. 3 is a diagram illustrating the arrangement of the conductive sheet 30 shown in FIG. 2. In FIG. 3, the conductive sheet 30 is shown with a dot pattern for clarity.
[0024] As shown in FIGS. 2 and 3, the conductive sheet 30 of the present embodiment has a first portion 30a to a fifth portion 30e. The first portion 30a to the third portion 30c are provided along the respective edge portions on the Y1, X1, and X2 sides of the plate portion 24, and are formed in a substantially U shape that is upside down as a whole. The first portion 30a extends in the X direction along the Y1-side edge portion of the plate portion 24. The second portion 30b extends in the Y direction along the X1-side edge portion of the plate portion 24, and its Y2-side end is connected to the bracket 28. The third portion 30c extends in the Y direction along the X2-side edge portion of the plate portion 24, and its Y2-side end is connected to the bracket 28. The fourth portion 30d is provided at a position closer to Y2 than the center of the plate portion 24, and is formed in a substantially J shape facing sideways. The fourth portion 30d is connected to the relay connector 32a of the wiring portion 32 and the left and right brackets 28, respectively. It is preferable that the portions 30b to 30d are tightened together with the screws for fixing the hinge 14 to the bracket 28 to ensure electrical continuity with respect to the bracket 28.
[0025] The fifth portion 30e is a small piece-shaped portion that protrudes toward the Y1 side from a position facing the camera module 34 in the longitudinal direction (X direction) of the first portion 30a. The fifth portion 30e is bent toward the Z1 side along the wall surface (inner wall surface) 25a of the standing wall 25, and then folded back toward the Y2 side (see FIG. 6). Thereby, the fifth portion 30e is provided so as to enclose a part of the camera module 34. The specific configuration of the fifth portion 30e will be described later.
[0026] As shown in FIG. 2, the wiring portion 32 is composed of a wide flexible printed circuit (FPC). The wiring portion 32 is placed on the inner surface 24a of the plate portion 24 and the Z1-side surface of the conductive sheet 30 attached thereto. The wiring portion 32 is a part of the wiring that connects the camera module 34 and the microphone module 36 to the motherboard 15 on the second housing 12 side. The wiring portion 32 is a combination of the flexible substrate 47 of the camera module 34 and the flexible substrates 36b of the respective microphone modules 36, which will be described later. A relay connector 32a for connecting to a predetermined relay substrate is mounted at the Y2-side end of the wiring portion 32. The wiring portion 32 is connected to the motherboard 15 via this relay substrate. The wiring portion 32 may be directly connected to the motherboard 15 without passing through the relay substrate.
[0027] A pair of left and right microphone modules 36 are provided to form a stereo microphone. Only one microphone module 36 may be used. The microphone module 36 has a microphone element 36a. The microphone element 36a is, for example, a MEMS chip having a diaphragm mounted on a printed circuit board (PCB) or a MEMS microphone shielding an IC chip. A microphone hole 25c is formed through the standing wall 25 at a position where the microphone module 36 faces. The microphone element 36a is adhesively fixed to the wall surface 25a of the standing wall 25, and can acquire sound information outside the first housing 11 through the microphone hole 25c. The microphone element 36a of the present embodiment is mounted on a flexible substrate (FPC) 36b. The flexible substrate 36b is wiring that connects the microphone element 36a and the wiring portion 32.
[0028] As shown in FIG. 2, the camera module 34 of the present embodiment includes a substrate (camera substrate) 40, a connector portion 41, a lens portion 42, and component portions 43 and 44.
[0029] The substrate 40 is a printed circuit board (PCB). The substrate 40 is narrow in the Z direction and is a thin strip-shaped plate that is long in the X direction. The connector portion 41, the lens portion 42, and the component portions 43 and 44 are mounted on one surface (the Z1-side surface) of the substrate 40 so as to be arranged in the X direction.
[0030] The connector portion 41 can include a connector 46 and a flexible printed circuit (FPC) 47. The connector 46 is mounted on the X1-side end of the substrate 40. The connector 46 is, for example, a board-to-board connector (BtoB connector). The connector 46 has connection terminals formed on its upper surface (Z1-side surface) 46a, and the flexible printed circuit 47 is connected thereto (see FIG. 5). The upper surface 46a is the surface on the opposite side of the mounting surface (Z2-side surface) of the connector 46 with respect to the substrate 40. The flexible printed circuit 47 is a wiring that connects the camera module 34 and the wiring portion 32.
[0031] The lens portion 42 can include an illuminance sensor 42a, a camera lens 42b, a status LED 42c, and an IR LED 42d (see also FIG. 1). The illuminance sensor 42a is a sensor that can detect the brightness of the surrounding environment. The camera lens 42b is a camera that can be used for video shooting and the like, has a condensing lens at the center, and an image sensor is provided on the back side of the lens. The status LED 42c is a light that can display the operating state of the electronic device 10. The IR LED 42d is an infrared camera that can be used for face recognition and the like. The configuration of the lens portion 42 is not limited to this.
[0032] The component part 43 is disposed between the connector part 41 and the lens part 42. The component part 43 can include various components 43a mounted on the substrate 40 and a shield case 43b that covers the components 43a (see FIGS. 4A and 5). The components 43a can include, for example, a semiconductor chip that processes signals sent from the camera lens 42b to the connector 46, a semiconductor chip for power supply of the camera module 34, and the like. The shield case 43b is a case for electromagnetic shielding of the components 43a, and is, for example, a box-shaped case made of aluminum.
[0033] The component part 44 is disposed on the X2 side of the lens part 42. The component part 44 may have the same configuration as the component part 43, that is, it can be configured such that the periphery of various components is surrounded by a shield case.
[0034] In the camera module 34, the connector part 41 is a part that particularly requires electromagnetic shielding for electrostatic countermeasures and noise countermeasures. For example, if static electricity drops on the connector part 41, there is a concern that this static electricity will be transmitted from the flexible substrate 47 through the wiring part 32 to the motherboard 15 in the second housing 12 and destroy the CPU or the like. Also, if the noise generated by each component of the camera module 34 is transmitted to the connector 46, there is a concern that the video quality will deteriorate. Therefore, in the connector part 41 of the present embodiment, the Z2 side (substrate 40 side) is covered with the first part 30a of the conductive sheet 30, and the Z1 side (surface 41a side) is covered with the fifth part 30e.
[0035] Next, a specific shielding structure of the connector part 41 will be described.
[0036] FIG. 4A is an enlarged view of the connector part 41 shown in FIG. 3 and its peripheral part. In FIGS. 4A and 3, only the outer shape of the fifth part 30e is shown by a two-dot chain line, and the illustration of the pressing member 52 is omitted. FIG. 4B is a view showing a state in which the connector part 41 shown in FIG. 4A is covered with the fifth part 30e. FIG. 5 is a schematic cross-sectional view taken along the line V-V in FIG. 4B. FIG. 6 is a schematic cross-sectional view taken along the line VI-VI in FIG. 4B.
[0037] As shown in FIG. 3, the fifth portion 30e of the conductive sheet 30 is formed so as to protrude in the Y1 direction from the Y1-side edge portion of the first portion 30a in a state before covering the connector portion 41. As shown in FIGS. 4A to 6, when covering the connector portion 41, the fifth portion 30e is bent along the wall surface 25a of the standing wall 25 to the Z1 side and then folded back to the Y2 side. Thereby, the fifth portion 30e can cover the connector portion 41 so as to enclose it.
[0038] As shown in FIGS. 3 to 6, the fifth portion 30e is composed of a sheet-like member having a three-layer structure including a shield layer 50a and insulating layers 50b, 50b that cover both surfaces of the shield layer 50a. Hereinafter, the fifth portion 30e may also be referred to as a "sheet-like member 30e". The shield layer 50a is a part of the conductive sheet 30 formed integrally with the first portion 30a and is, for example, an aluminum sheet. The insulating layer 50b is formed of a resin having insulation and flexibility, for example, a polyimide sheet. The insulating layer 50b is provided to prevent the camera module 34 from being short-circuited by the shield layer 50a. Such a sheet-like member (fifth portion) 30e having a three-layer structure has a greater thickness by the two insulating layers 50b than the other portions 30a to 30d, and its flexibility is reduced.
[0039] As shown in FIGS. 4A to 5, the sheet-like member 30e is installed so as to cover from the surface 41a of the connector portion 41 to a part of the surface 43c of the component portion 43 adjacent to the connector portion 41. The reason why the sheet-like member 30e is installed so as to cover not only the connector portion 41 but also the component portion 43 is mainly as follows. First, the gap C between the connector portion 41 and the component portion 43 is very narrow for miniaturization of the camera module 34. The gap C is, for example, about 1 mm. Therefore, it is difficult for the sheet-like member 30e to cover only the connector portion 41. On the other hand, it is necessary to prevent a gap serving as a path for noise or the like from being formed between the sheet-like member 30e and the connector portion 41. Therefore, the sheet-like member 30e is installed so as to cover up to the component portion 43 together with the connector portion 41, and suppresses as much as possible the formation of a gap around the connector portion 41.
[0040] As shown in FIGS. 4B to 6, the electronic device 10 can also include a pressing member 52 that presses the sheet-like member 30e from above and presses the flexible substrate 47 against the connector 46. The pressing member 52 is a member for preventing the connection between the connector 46 and the flexible substrate 47 from coming off. The pressing member 52 is, for example, a rod-shaped member formed of resin or metal. The pressing member 52 in the present embodiment is a resin rod. The pressing member 52 is fastened with a screw 52a to the upper surface of a boss portion standing up from the inner surface 24a of the housing member 20, and protrudes in the X2 direction. Thereby, the pressing member 52 can press the connector portion 41 from above the sheet-like member 30e toward the Z2 side.
[0041] As shown in FIG. 5, a step D is formed between the surface 41a of the connector portion 41 and the surface 43c of the component portion 43. Specifically, the height from the surface of the substrate 40 to the surface 43c of the component portion 43 is higher than the height from the surface of the substrate 40 to the surface 41a of the connector portion 41.
[0042] The camera module 34 has different heights for the component parts 43 and 44 and the lens part 42 depending on whether it supports the USB Video Class (UBC) with a resolution of about 720×480 pixels to about 1920×1200 pixels, or whether it supports 4K with a higher resolution. The heights of the component part 43 and the lens part 42 also vary depending on the product manufacturer. On the other hand, the connector part 41 can be composed of a thin connector 46 that complies with a predetermined connection standard, and ones with a common height can be used regardless of the resolution or the manufacturer. For this reason, a step D is formed between the surfaces 41a and 43c. Note that the arrangement of each component of the camera module 34 may be changed as appropriate. For example, the lens part 42 may be arranged next to the connector part 41.
[0043] Here, without considering the above-described step D, the experimental results of considering a configuration in which the surfaces 41a and 43c are covered with the sheet-like member 30e that does not have the hole part 54 described later will be described. In this case, as shown in FIG. 7, it was found that the sheet-like member 30e bulges toward the Z1 side like a tent above the gap C between the surfaces 41a and 43c due to the step D. In particular, the sheet-like member 30e has the above-described three-layer structure. Therefore, the sheet-like member 30e is thicker and less flexible than the other parts 30a to 30d of the conductive sheet 30. Therefore, it is even more difficult for the sheet-like member 30e to follow the step D, and it is more likely to bulge in a tent shape above the gap C. For this reason, in this configuration, it was found that a large gap G is generated between the bulged sheet-like member 30e at the portion straddling the gap C and the periphery of the connector part 41, and there is a concern that the gap G may serve as a passage for noise or the like. Furthermore, it was also found that the bulged sheet-like member 30e presses the pressing member 52 toward the Z1 side and deforms it. In this case, there is a concern that the pressing member 52 not only loses the pressing action on the connector part 41 but also interferes with the bezel member 21 and peels off.
[0044] Therefore, the sheet-like member 30e of the present embodiment has a hole part 54 for suppressing bulging between the surfaces 41a and 43c.
[0045] As shown in FIGS. 3 to 6, the hole portion 54 is provided near the center in the X direction of the sheet-like member 30e and is a long hole extending in the Y direction. The hole portion 54 is provided at a position where a part thereof overlaps the gap C in the vertical (Z direction). The hole portion 54 needs to be able to substantially divide the sheet-like member 30e into two parts in the X direction at the portion straddling the gap C. The portion 30e1 on the X1 side is a portion covering the connector portion 41. The portion 30e2 on the X2 side is a portion covering a part of the component portion 43. Note that the portions 30e1 and 30e2 are fixed to the surfaces 41a and 43c with, for example, double-sided adhesive tape.
[0046] Thereby, in the sheet-like member 30e, the lower portion 30e1 in the Z direction is prevented from being pulled by the upper portion 30e2 and bulging toward the Z1 side in a tent shape. For this reason, the sheet-like member 30e can surely cover the surface 41a of the connector portion 41 and its peripheral portion without a gap.
[0047] More specifically, it is preferable that the side edge portion 54a on the X1 side of the hole portion 54 is located at a position protruding to the X2 side beyond the X2 side surface of the connector portion 41 (see FIGS. 4B and 5). Thereby, the sheet-like member 30e can more surely cover the surface 41a of the connector portion 41 and its peripheral portion with the portion 30e1 on the X1 side. Note that the side edge portion 54b on the X2 side is located at a position recessed to the X2 side from the X1 side surface of the component portion 43.
[0048] It is preferable that the end portion 54c on the Y1 side of the hole portion 54 is located on the Z1 side with respect to the upper surface 46a of the connector 46 (see FIG. 6). In other words, it is preferable that the hole portion 54 is not disposed between the connector 46 and the wall surface 25a of the standing wall 25. This is to surely dispose the shield layer 50a on the Y1 side of the connector 46 and enhance the shielding performance against the connector 46. From the viewpoint of shielding performance, it is more preferable that the end portion 54c is located on the Z1 side with respect to the surface 41a of the connector portion 41 including the flexible substrate 47. However, since the surface of the flexible substrate 47 is covered with an insulating material, electromagnetic shielding such as that of the connector 46 is not essential. Therefore, it is sufficient that the end portion 54c is located at least on the Z1 side with respect to the upper surface 46a of the connector 46. Then, the sheet-like member 30e further improves the shielding performance of the connector 46 while ensuring the performance of absorbing the step D by the hole portion 54.
[0049] The end portion 54d on the Y2 side of the hole portion 54 may be located at a position that does not interfere with the performance of absorbing the step D by the hole portion 54. For example, the end portion 54d may be located on the Y2 side with respect to the side surface on the Y2 side of the connector portion 41 (see FIG. 6).
[0050] The size of the hole portion 54 is not limited. In the case of the present embodiment, the width of the sheet-like member 30e in the X direction is, for example, about 15 mm, the width of the hole portion 54 in the X direction is, for example, about 1 mm to 3 mm, and is 2 mm in the present embodiment. Further, for the shielding performance, it is preferable that the width of the portion 30e1 covering the connector portion 41 in the X direction of the sheet-like member 30e is slightly larger than the width of the portion 30e2. For example, the width of the portion 30e1 in the X direction is about 7.5 mm, and the width of the portion 30e2 in the X direction is about 5 mm.
[0051] As described above, the electronic device 10 of the present embodiment includes a sheet-like member 30e for electromagnetic shielding provided so as to cover from the surface 41a of the connector portion 41 of the camera module 34 across the gap C having a step D to the surface 43c of another component of the camera module 34, for example, the component portion 43. The sheet-like member 30e has a hole portion 54 at a position overlapping the gap C vertically. Therefore, in the electronic device 10, the sheet-like member 30e is suppressed from stretching in a tent shape between the connector portion 41 and another adjacent component (component portion 43). For this reason, the sheet-like member 30e can cover the connector portion 41 without gaps, and the shielding property in the camera module 34 can be ensured. In other words, the electronic device 10 does not need to selectively use the sheet-like member 30e depending on the resolution of the camera module 34 or the product manufacturer, and the component cost can be suppressed.
[0052] Moreover, the sheet-like member 30e is configured to follow the step D by the hole portion 54 surrounded by the shielding layer 50a on the periphery. That is, in order to follow the step D, the sheet-like member 30e may form a cut from, for example, the edge portion on the opposite side of the connecting portion with the first portion 30a (the Y2-side edge portion in FIG. 4B) in the Y1 direction to form the portions 30e1 and 30e2. However, in this case, there is a concern that the shielding layer 50a is divided at the Y2-side edge portion of the sheet-like member 30e, and this portion may become a path for noise. In particular, when the shielding layer 50a is divided in this way, there is a possibility that an operator may open the portions 30e1 and 30e2 in a skirt shape and fix them from the cut during assembly in the factory, further reducing the shielding property. In this regard, the sheet-like member 30e of the present embodiment has bridge portions 30e3 and 30e4 that connect the left and right portions 30e1 and 30e2 outside both end portions 54c and 54d of the hole portion 54. For this reason, the shielding layers 50a of the portions 30e1 and 30e2 of the sheet-like member 30e are connected to each other, and higher shielding performance can be obtained.
[0053] In particular, the height of the camera module 34 from one surface of the substrate 40 to the surface 43c of the other component (component portion 43) is higher than the height from one surface of the substrate 40 to the surface 41a of the connector portion 41. For this reason, the camera module 34 is more likely to generate a gap G as shown in FIG. 7 between the sheet-like member 30e and the connector portion 41. In this regard, the electronic device 10 can more reliably shield the connector portion 41, which is lower in height than other adjacent components, by providing the hole portion 54 in the sheet-like member 30e.
[0054] Note that the present invention is not limited to the above-described embodiments, and it goes without saying that it can be freely changed without departing from the gist of the present invention.
