[0004] In recent years, there has been a growing demand for repairing electronic devices to extend their useful life. However, depending on the structure of the electronic device, it may be difficult to assemble or repair the device by the user. For this reason, there is a demand for technology that makes it easy to assemble and repair electronic devices.

[0005] In view of the above circumstances, an object of the present technology is to provide an electronic device that is easy to assemble and repair.

[0006] To achieve the above object, according to one aspect of the present technology, an electronic device includes a first device unit, a second device unit, and a holder component. The first device unit includes a first connector that is a board-to-board connector, a first connector board on which the first connector is provided, and an opening for exposing a connection port of the first connector. The second device unit includes a second connector connected to the first connector and a second connector board on which the second connector is provided. The holder component covers at least a portion of the opening, is detachably fixed to the first device unit, and holds the second connector board so that the second connector is positioned to connect with the first connector.

[0007] In this electronic device, a second connector provided on a second connector board of a second device unit is connected to a first connector provided on a first connector board of a first device unit and exposed through an opening. At this time, the second connector board is held by a holder component that covers at least a portion of the opening and is detachably fixed to the first device unit. This allows the second connector to be held in an appropriate connection position above the opening, facilitating assembly, for example, even when the second device unit is first placed. Furthermore, when repairing the electronic device, the holder component can be detached to easily connect the first connector and the second connector, facilitating removal or replacement of the second device unit, for example. As a result, an electronic device that is easy to assemble and repair can be realized.

[0009] Hereinafter, embodiments of the present technology will be described with reference to the drawings.

[0010] [Configuration of Electronic Device] Fig. 1 is a perspective view showing an example of an electronic device including a holder component according to an embodiment of the present technology. The electronic device 100 according to this embodiment is an electronic device such as a smartphone. The electronic device 100 is configured as a long, thin, plate-like device overall, and a display 1 is provided on one surface. In addition, a connection port 2 for connecting a cable or the like is provided on a side surface along one short side of the electronic device 100.

[0011] Hereinafter, the surface of electronic device 100 on which display 1 is provided will be referred to as the front surface, and the surface opposite to the surface on which display 1 is provided will be referred to as the back surface. Furthermore, the side of electronic device 100 on which connection port 2 is provided will be referred to as the lower side, and the opposite side will be referred to as the upper side. Furthermore, three mutually orthogonal axial directions will be referred to as the X direction, Y direction, and Z direction, and the direction along the short side of electronic device 100 will be referred to as the X direction (horizontal direction), the direction along the long side will be referred to as the Y direction (vertical direction), and the thickness direction of electronic device 100 will be referred to as the Z direction.

[0012] The electronic device 100 is configured by combining multiple units. Here, a unit is a structure made up of a collection of parts or individual parts. For example, a unit configured by combining multiple parts can be treated as a single part (module) by itself.

[0013] Fig. 2 is a perspective view showing an electronic device equipped with a holder component in an open state. Fig. 2 schematically illustrates a state in which the display 1 of the electronic device 100 is open from the same direction as Fig. 1. In this way, the electronic device 100 is configured so that the display 1 can be opened. This allows, for example, repairs to be performed separately for the unit including the display 1 and the other units.

[0014] As shown in Fig. 2, the electronic device 100 has a main unit 10, a display unit 20, and a holder component 30. The holder component 30 is provided inside the electronic device 100, and therefore cannot be seen from the outside when the electronic device 100 is assembled as shown in Fig. 1. In this embodiment, the main unit 10 corresponds to a first device unit, and the display unit 20 corresponds to a second device unit.

[0015] The main unit 10 is a unit that constitutes the main body of the electronic device 100. In this case, the main unit 10 is a unit that contains all components excluding the display unit 20 and the holder component 30 (for example, various circuit boards, communication antennas, sensors, vibration elements, speakers, and batteries) in a housing.

[0016] The main unit 10 has a main frame 11. The main frame 11 is a structural member that houses and holds the components that make up the main unit 10, and functions as a housing for the electronic device 100. Note that the main unit 10 may be provided with another frame (for example, a rear frame provided on the back side) in addition to the main frame 11. As shown in FIG. 2 , the main frame 11 has a plate portion 12 and a side portion 13.

[0017] The plate portion 12 is a plate-like structural part formed mainly along the XY plane. In the electronic device 100, when the display 1 (display unit 20) is opened, the plate portion 12 of the main frame 11 is exposed. Steps, openings, etc. are appropriately formed in the plate portion 12 to match the shapes of each component. The side portion 13 is a structural part that surrounds the plate portion 12 and forms the outer surface of the electronic device 100. Each component of the main unit 10 is appropriately arranged within the space surrounded by the plate portion 12 and the side portion 13. In addition, a cover member such as a back panel (not shown) is attached to the opposite side (back side) of the main frame 11 from the plate portion 12.

[0018] Hereinafter, the surface of the main frame 11 facing the display unit 20 will be referred to as the first surface, and the surface opposite to the first surface will be referred to as the second surface. Here, the front surface of the plate portion 12 will be referred to as the first surface, and the back surface of the plate portion 12 will be referred to as the second surface.

[0019] An opening 15 is formed on the front surface of the main unit 10 (the surface facing the display unit 20) to allow connection components (a second flexible substrate 22, described later) to pass through. In this example, the opening 15 is formed below the main frame 11 (plate portion 12) when viewed from the front side. In this embodiment, the main frame 11 corresponds to a frame in which an opening is formed. In FIG. 2 , the connection components to the display unit 20 are connected via the opening 15, and a holder component 30 is attached to the opening 15.

[0020] FIG. 3 is a schematic diagram showing an example of an opening 15 provided in the main unit 10. FIG. 3 is a schematic plan view of the opening 15 as seen from the front side of the main unit 10. In this figure, the connecting component (second flexible substrate 22) extending from the display unit 20 and the holder component 30 have been removed. As shown in FIG. 3, the main unit 10 has a first flexible substrate 16, a first connector C1, and the above-described opening 15. In this embodiment, the first flexible substrate 16 corresponds to the first connector substrate.

[0021] The first flexible substrate 16 is a flexible printed circuit (FPC) disposed along the main frame 11 and provided with the first connector C1. As shown in FIG. 3 , the first flexible substrate 16 is disposed on the rear side of the main frame 11 (plate portion 12). Wiring and the like connected to each terminal of the first connector C1 are formed on the first flexible substrate 16. The first flexible substrate 16 functions, for example, as a relay substrate (relay FPC) for connecting the first connector C1 to a main circuit board or the like on which a processing element such as a CPU is mounted. Note that the configuration of the substrate (first connector substrate) on which the first connector C1 is provided is not limited, and for example, a rigid substrate or the like may be used instead of a flexible substrate.

[0022] The first connector C1 is a board-to-board connector. That is, the first connector C1 is a connector for connecting two boards face to face, and is also called a BtB (Board to Board) connector. In this case, the connection port (terminal port) of the first connector C1 faces the front side of the main unit 10.

[0023] The opening 15 is a through-hole provided in the main frame 11 (plate portion 12) that exposes the connection port of the first connector C1. Specifically, the opening 15 is formed with a size that allows the entire connection port of the first connector C1 to be seen when viewed from the front side. This makes it possible, for example, to insert another connector (a second connector C2, described below) into the first connector C1 from the front side of the opening 15. In FIG. 3 , the area corresponding to the opening 15 is schematically illustrated by a dotted rectangular area. In this way, the opening 15 allows access to the first connector C1 provided inside the main frame 11 from the front side.

[0024] 2, the display unit 20 is a unit including the display 1, and is configured to be detachable from the main unit 10. The display unit 20 has the above-described display 1, a wiring connection portion 21, and a second flexible substrate 22. In this embodiment, the second flexible substrate 22 corresponds to a second connector substrate.

[0025] The display 1 is a display device that is mounted on the front of the electronic device 100 and displays images, etc. Note that Fig. 2 illustrates the rear side of the display 1. For example, a liquid crystal display, an organic EL display, etc. may be used as the display 1. In addition, the specific configuration of the display 1 is not limited, and any display device that can be mounted on the electronic device 100 may be used.

[0026] The wiring connection section 21 is provided on the rear surface of the display 1, and connects the wiring provided on the second flexible substrate 22 to the wiring inside the display 1. For example, the wiring connection section 21 directly connects the second flexible substrate 22 to the display 1 without using a connector or the like.

[0027] The second flexible substrate 22 is a bendable wiring substrate (FPC). The second flexible substrate 22 functions as wiring (Display FPC) that connects the display 1 to the main unit 10. One end of the second flexible substrate 22 is connected to the wiring connection portion 21. A second connector that connects to the first connector C1 is provided at the other end of the second flexible substrate 22. Note that the second connector is not visible in FIG. 2 .

[0028] Fig. 4 is a schematic cross-sectional view showing the internal structure of an electronic device equipped with the holder component 30. Fig. 4 shows a schematic cross-section of the assembled electronic device 100 cut along the XZ plane so as to pass through the opening 15 of the main unit 10. In Fig. 4, the display unit 20 is arranged on the upper side of the drawing, and the main unit 10 is arranged below it.

[0029] 4, when the electronic device 100 is assembled, the second flexible substrate 22 extending from the wiring connection portion 21 is bent 180 degrees overall and accommodated between the main frame 11 and the display 1. In addition, a second connector C2 and a reinforcing plate 23 are provided at the tip portion of the second flexible substrate 22 opposite to the wiring connection portion 21.

[0030] The second connector C2 is a connector connected to the first connector C1 and is a board-to-board connector provided on the second flexible substrate 22. For example, if the first connector C1 is a plug type, the second connector C2 is a socket type. Conversely, if the first connector C1 is a socket type, the second connector C2 is a plug type. The second connector C2 is provided on the surface facing the rear side when the second flexible substrate 22 is bent 180 degrees as shown in FIG. 4 (here, the same surface as the side connected to the wiring connection portion 21).

[0031] The reinforcing plate 23 is a plate-like member disposed on the opposite side of the second connector C2 across the second flexible substrate 22. The reinforcing plate 23 suppresses deformation of the second connector C2, for example, when the second connector C2 is inserted into the first connector C1. The shape and size of the reinforcing plate 23 are appropriately set so that the second connector C2 fits inside the reinforcing plate 23, for example, to a extent that it does not protrude from the second flexible substrate 22.

[0032] Returning to FIG. 2 , the holder part 30 covers at least a portion of the opening 15 and is detachably fixed to the main unit 10. For example, the holder part 30 may cover the entire opening 15, or may cover only a portion of the opening. The holder part 30 is configured so that it can be attached to and detached from the main unit 10 without using screws, adhesive seals, or the like. In this embodiment, the holder part 30 is detachably fixed to the main frame 11. A specific mechanism for fixing the holder part 30 to the main frame 11 will be described in detail later.

[0033] The holder part 30 also holds the second flexible board 22 so that the second connector C2 is positioned at the connection position with the first connector C1. Therefore, it can also be said that the holder part 30 is a part that holds the flexible second flexible board 22 in the correct assembly position above the opening 15.

[0034] 4, when the electronic device 100 is assembled, the tip portion of the second flexible substrate 22 (the second connector C2 and the reinforcing plate 23) is arranged along the back side of the holder part 30 fixed to the main frame 11. The second connector C2 is connected to the first connector C1 provided on the front side of the first flexible substrate 16. The first flexible substrate 16 (first connector C1) is supported by a predetermined support part 17 (such as a speaker box or another substrate) arranged on the back side thereof.

[0035] For example, even when the display unit 20 is attached to the main frame 11 without the first connector C1, the holder part 30 holds the second flexible board 22 so that the second connector C2 is in a position where it can be connected to the first connector C1. In other words, even without the first connector C1, the holder part 30 holds the second flexible board 22 above the opening 15, maintaining a state where assembly is possible.

[0036] The holder part 30 also functions as a lid that holds the second connector C2 (second flexible substrate 22) from the side opposite the first connector C1 (the upper side in the figure). This allows the holder part 30 to prevent the second connector C2 from coming off the first connector C1. The specific configuration of the holder part 30 will be described below.

[0037] [Configuration of Holder Component] Fig. 5A is a perspective view of an example of the holder component 30 as seen from the front side. Fig. 5B is a perspective view of an example of the holder component 30 as seen from the rear side. Fig. 6A is a perspective view of the holder component 30 attached to the main frame 11 as seen from the front side. Fig. 6B is a perspective view of the holder component 30 attached to the main frame 11 as seen from the rear side.

[0038] 5A and 5B, the holder part 30 is a plate-shaped member as a whole. A rigid structural member is used for the holder part 30, and the holder part 30 is configured so as not to be deformed and come off the main frame 11 even when subjected to a certain level of external force.

[0039] In this embodiment, the holder part 30 is made of a resin material. Examples of the resin material include general-purpose plastics such as polypropylene and engineering plastics such as polycarbonate. By using a resin material, the antenna performance of the electronic device 100 is less likely to be affected even if the mounting position of the holder part 30 is misaligned.

[0040] The holder part 30 has a holding plate 31 and a fixing part 40. The holding plate 31 is a plate-shaped structural part that forms the main body of the holder part 30. Here, the planar shape of the holding plate 31 is a rectangle that is elongated in the horizontal direction (X direction), but this may be set appropriately depending on the shape of the opening 15 and the second flexible substrate 22, for example. As shown in FIG. 6B , the second flexible substrate 22 is held along the back surface of the holding plate 31. An arrow 33 indicating the insertion direction of the holder part 30 is engraved on the front surface of the holding plate 31. As shown in FIG. 5A , the direction in which the holder part 30 is moved to the left is the insertion direction of the holder part 30.

[0041] The retaining plate 31 also has side portions 34 that fit into the opening 15. The side portions 34 are wall-like structural parts that are formed along the upper and lower edges of the retaining plate 31 and protrude from the retaining plate 31 toward the rear side. The side portions 34 are inserted into the inside of the opening 15. Therefore, the distance between the outer surfaces 35 of the side portions 34 (the side surfaces facing upward in the upper side portion 34 and the side surfaces facing downward in the lower side portion 34) is set to be the same as or slightly smaller than the vertical width of the opening 15.

[0042] 5B , a U-shaped groove is formed on the back side of the holder part 30, surrounded by the back surface of the holding plate 31 and the inner surfaces 36 of each side portion 34 (the side surface facing downward in the upper side portion 34, and the surface facing upward in the lower side portion 34). The width of this groove (the distance between the inner surfaces 36 of each side portion 34) is set so that the second flexible board 22 can be inserted.

[0043] The fixing portion 40 is provided on the holding plate 31 and detachably fixes the holding plate 31 to the main frame 11. In this embodiment, two fixing mechanisms (a first fixing mechanism 41 and a second fixing mechanism 42) are provided as the fixing portion 40 to fix the holding plate 31 to the main frame 11.

[0044] The first fixing mechanism 41 is a mechanism for fixing the holding plate 31 so as not to move in the thickness direction (Z direction) of the main frame 11. The first fixing mechanism 41 also functions as a pressure-resistant mechanism for preventing the holding plate 31 from coming off the main frame 11 even when an external force acts on the holding plate 31 from the front or rear side.

[0045] In this embodiment, the first fixing mechanism 41 has a hook structure that holds the main frame 11 from both the first surface 11f (the front surface of the plate portion 12) and the second surface 11b (the back surface of the plate portion 12) around the opening 15. Specifically, the first fixing mechanism 41 has a first hook 43 and a second hook 44.

[0046] The first hook 43 is a hook that protrudes from the side surface portion 34 and presses against the first surface 11f. As shown in Figures 5A and 5B, in this embodiment, one first hook 43 is formed on one side surface portion 34. The first hook 43 is a structural part of a substantially rectangular parallelepiped shape that protrudes by a predetermined width from a portion of the outer surface 35 of the side surface portion 34 that is close to the front surface of the retaining plate 31 in the thickness direction (Z direction). Here, the first hook 43 that is elongated in the horizontal direction is formed in the central portion of the outer surface 35 in the horizontal direction (X direction). The front surface of the first hook 43 is formed so as to be flush with the front surface of the retaining plate 31.

[0047] The second hooks 44 are hooks that protrude from the side surface portion 34 and press against the second surface 11b. As shown in Figures 5A and 5B, in this embodiment, two second hooks 44 are formed on one side surface portion 34. The second hooks 44 are structural parts that are approximately rectangular parallelepiped and protrude by a predetermined width from a portion of the outer surface 35 of the side surface portion 34 that is opposite the front surface of the retaining plate 31 in the thickness direction (Z direction). In this example, the second hooks 44 that are long in the horizontal direction are formed on both end portions (right and left ends in the figures) of the outer surface 35 in the horizontal direction (X direction).

[0048] The distance in the thickness direction between the first hook 43 and the second hook 44, i.e., the distance between the back surface of the first hook 43 and the front surface of the second hook 44, is set to be the same as or slightly larger than the thickness of the plate portion 12 of the main frame 11. This makes it possible to sandwich the main frame 11 (plate portion 12) between the first hook 43 and the second hook 44, as shown in Figures 6A and 6B.

[0049] The back surface of the first hook 43 contacts the first surface 11f and presses it down, and the front surface of the second hook 44 contacts the second surface 11b and presses it down. Note that the back surface of the first hook 43 and the front surface of the second hook 44 may have an inclined surface formed on the insertion direction side so that they can easily fit along the main frame 11. In this way, in this embodiment, the first hook 43 and the second hook 44 press the main frame 11 from both sides, thereby fixing the retaining plate 31 so that it does not move in the thickness direction.

[0050] In this embodiment, the main frame 11 (plate portion 12) has cutout portions 18 formed on the inner periphery of the opening 15, through which the second hooks 44 pass. For example, as shown in FIG. 4 above, the cutout portions 18 have a structure in which the inner periphery of the opening 15 is partially widened outward. The opening 15 has four cutout portions 18 formed therein, through which the four second hooks 44 provided on the holder part 30 pass.

[0051] The second fixing mechanism 42 is a mechanism that fixes the holder part 30 so as not to move in a planar direction (in-plane direction of the XY plane) perpendicular to the thickness direction of the main frame 11. In other words, the second fixing mechanism 42 is a mechanism that prevents the holding plate 31 from shifting in the horizontal direction (X direction) and vertical direction (Y direction).

[0052] As described above, in this embodiment, the vertical width of the side surface portion 34 of the holder part 30 is substantially the same as the vertical width of the opening 15, making it difficult for the holder part 30 to move in the vertical direction. For this reason, the holder part 30 is provided with a mechanism that mainly prevents movement in the horizontal direction.

[0053] In this embodiment, a dowel structure having a beam portion 45 and a dowel portion 46 is used as the second fixing mechanism 42. The beam portion 45 is a portion that protrudes from the outer periphery of the holding plate 31 and functions as a cantilever beam that supports the dowel portion 46. As shown in FIGS. 5A and 5B , the beam portion 45 is provided so as to protrude from the short side of the holding plate 31 on the insertion direction side. Furthermore, when the holder component 30 is attached, the beam portion 45 is disposed above the main frame 11 (plate portion 12). The thickness of the beam portion 45 may be the same as that of the holding plate 31, or may be thinner than that of the holding plate 31 to facilitate deformation during insertion.

[0054] The dowel portion 46 is a portion that protrudes from the surface of the beam portion 45 facing the main frame 11. In this example, the dowel portion 46 is formed to protrude in a circular shape from the back surface of the beam portion 45. The dowel portion 46 is also formed at the tip of the beam portion 45. The amount of protrusion of the dowel portion 46 is set to be approximately the same as the thickness of the main frame 11, for example.

[0055] 3 and other figures, the main frame 11 is provided with dowel receiving portions 19 around the opening 15, into which the dowel portions 46 fit. The dowel receiving portions 19 may be through holes or grooves, as long as they are deep enough to fit the dowel portions 46. In this example, the through holes formed on the left side of the opening 15 in the drawing serve as the dowel receiving portions 19.

[0056] 6B shows a state in which the dowel portion 46 of the holder part 30 is fitted into the dowel receiving portion 19 of the main frame 11. With the dowel portion 46 fitting into the dowel receiving portion 19 in this way, the holder part 30 is prevented from moving in the lateral direction (X direction). This fixes the position of the holder part 30, which was able to slide along the opening 15. Note that in order to reduce resistance when inserting or removing the holder part 30, a sloped or curved surface may be formed on the outer periphery of the dowel portion 46.

[0057] The holder part 30 is also provided with a floating prevention hook 47 that prevents the second flexible substrate 22 from floating up. The floating prevention hook 47 is a hook that holds the second flexible substrate 22 along the back side (U-shaped groove) of the holding plate 31.

[0058] As shown in FIGS. 5B and 6B , the float prevention hook 47 is provided on the inner surface 36 of one of the two side surface portions 34 protruding toward the rear side of the holding plate 31. Specifically, the float prevention hook 47 is a structural part having a substantially rectangular parallelepiped shape that protrudes a predetermined width from one of the inner surfaces 36. The distance in the Z direction between the float prevention hook 47 and the rear surface of the holding plate 31 (the gap of the float prevention hook 47) is set to match the thickness of the second flexible substrate 22 (more precisely, the combined width of the second flexible substrate 22 and the reinforcing plate 23 of the second connector C2). For example, the gap of the float prevention hook 47 may be narrower than the combined width of the second flexible substrate 22 and the reinforcing plate 23. In this case, pushing (press-fitting) the second flexible substrate 22 can sufficiently prevent the second flexible substrate 22 from floating up. Alternatively, the gap of the float prevention hook 47 may be set wider. In this case, the second flexible substrate 22 can be easily held down by sliding it.

[0059] The second flexible substrate 22 arranged along the back side of the holding plate 31 is held down by the anti-floating hooks 47. By providing the anti-floating hooks 47 in this manner, it is possible to prevent the second flexible substrate 22 from separating from the holding plate 31 and floating up, even when the second flexible substrate 22 is bent.

[0060] 7 is a perspective view showing the process of mounting the holder component 30 to the main frame 11. Although the second flexible substrate 22 is not shown in FIG. 7, the mounting process of the holder component 30 is the same even when the second flexible substrate 22 is provided.

[0061] 7, the holder part 30 is inserted into the mounting start position from the first surface 11f side of the main frame 11. For example, a user assembling or repairing the electronic device 100 may insert the holder part 30 into the mounting start position by pressing it with their fingers.

[0062] 7 shows the holder part 30 inserted into the mounting start position. In this case, the mounting start position is the position where the second hook 44 provided on the holder part 30 is inserted into the notch 18 formed around the opening 15. By providing the notch 18 in this way, it is no longer necessary to insert the holder part 30 from the edge of the opening 15, and it is possible to complete the mounting operation in a narrow space.

[0063] As shown in the lower part of Figure 7, when the holder part 30 inserted into the installation start position is slid in the insertion direction (direction of arrow 33), the first hook 43 and the second hook 44 constituting the first fixing mechanism 41 clamp the main frame 11. Furthermore, the dowel portion 46 constituting the second fixing mechanism 42 is pushed up by the main frame 11 during the sliding process. At this time, the beam portion 45 is elastically deformed, but when the holder part 30 reaches the installation position, the dowel portion 46 is inserted into the dowel receiving portion 19 of the main frame 11, and the elastic deformation of the beam portion 45 is released. As a result, the installation state shown in Figures 6A and 6B is realized.

[0064] In this manner, in this embodiment, the holder part 30 is fixed by sliding along the main frame 11. To remove the holder part 30, the holder part 30 is simply slid in the opposite direction to the insertion direction. This allows the user to easily attach and detach the holder part 30 without using any special tools or adhesive materials for fixing.

[0065] The holder part 30 is fixed to the main frame 11 from the first surface 11f side facing the display unit 20. In other words, the holder part 30 can be attached and detached by opening the display unit 20. This makes it possible to easily replace the display unit 20 or perform other work with the display unit 20 removed without disassembling other parts of the main unit 10.

[0066] As described above, in the electronic device 100 according to this embodiment, the second connector C2 provided on the second flexible substrate 22 of the display unit 20 is connected to the first connector C1 provided on the main unit 10 through the opening 15 of the main frame 11. A strong holder part 30 is attached to this opening 15.

[0067] The holder part 30 is provided with a shape (first hook 43 and second hook 44) that embraces the main frame 11. This ensures the strength to withstand pressure from both the front and back sides of the main frame 11. It also makes it possible to hold the holder part 30 itself so that it does not easily come off the main frame 11.

[0068] The first hook 43 and the second hook 44 are formed along each surface of the main frame 11. This allows the holder part 30 to be attached to the main unit 10 by sliding it, making the attachment and detachment process easier.

[0069] The dowel shape (dowel portion 46) provided on the holder part 30 functions as a stopper in the sliding direction, thereby simultaneously realizing the positioning of the holder part 30 and the prevention of the first connector C1 and the second connector C2 from coming off.

[0070] Furthermore, a floating prevention hook 47 is provided on the back surface of the holder part 30. For example, during initial assembly (see FIG. 9, etc.), the second flexible board 22 (second connector C2) is held without the first connector C1 being installed. Even in such a case, the floating prevention hook 47 prevents the second flexible board 22 from floating up, making it possible to hold the second flexible board 22 in the correct connection position.

[0071] Fig. 8A is a perspective view of another example of the holder part as seen from the front side. Fig. 8B is a perspective view of another example of the holder part as seen from the back side. Up to this point, the holder part 30 made of a resin material has been described, but the constituent material of the holder part 30 is not limited. The holder part 30a shown in Figs. 8A and 8B is made of a metal material.

[0072] The basic shape of the holder part 30a is similar to that of the holder part 30 described with reference to Figures 5A and 5B, etc. Note that the holder part 30a is made of a metal material and is formed, for example, by bending or pressing a metal plate that serves as a base body. The base body of the holder part 30a is, for example, a metal flat plate from which a portion that serves as the first fixing mechanism 41 (the first hook 43 and the second hook 44) and a portion where the second fixing mechanism 42 (the beam portion 45 and the dowel portion 46) are formed protrude from a rectangular region that serves as the holding plate 31.

[0073] Of these, the four protruding portions that will become the second hooks 44 are bent into a crank shape so that their tips face outward to form the second hooks 44. The two protruding portions that will become the first hooks 43 are used as they are as the first hooks 43. The protruding portions where the beam portions 45 and dowel portions 46 are formed are formed with the dowel portions 46 by press working or the like. A U-shaped notch is formed in one of the second hooks 44 (here, the lower second hook 44 in the figure) formed on the side opposite the dowel portion 46. The portion surrounded by this notch is bent into a crank shape so that its tip faces inward to form the float prevention hook 47.

[0074] The holder part 30a may be made of any metal material, such as aluminum, stainless steel, or copper, but is not limited to these. By using a metal material, the rigidity of the holder part 30a can be increased compared to when a resin material is used, for example.

[0075] 9 is a schematic cross-sectional view showing an example of the assembly process of the electronic device 100. The steps (1) to (5) in FIG. 9 are schematic illustrations of a part of the process (initial assembly) for initially assembling the electronic device 100. In this embodiment, the display unit 20 is attached to the main frame 11, and then the main unit 10 is assembled.

[0076] First, as shown in Fig. 9(1), the holder part 30 is attached to the main frame 11. Fig. 10 is a perspective view showing how the holder part 30 is attached to the main frame 11 in the assembly process. In the attachment process of the holder part 30, as shown by the black arrow in Fig. 10, the second hook 44 is inserted into the notch 18 provided on the inner periphery of the opening 15, and then the holder part 30 is slid along the attachment direction, thereby attaching the holder part 30 to the main frame. This is the same process as the attachment process described with reference to Fig. 7.

[0077] Next, as shown in Fig. 9 (2), the second flexible substrate 22 of the display unit 20 is inserted into the opening 15. In the opening 15 to which the holder part 30 is attached, a gap is formed on the side opposite to the attachment direction of the holder part 30 (the right side in the figure). This gap functions as an insertion hole 25 for inserting the second flexible substrate 22. Fig. 11 is a perspective view showing the state in which the display unit 20 is attached to the main frame 11 in the assembly process, illustrating the step shown in Fig. 9 (2). As shown in Fig. 11, the second flexible substrate 22 of the display unit 20 is passed through the insertion hole 25 formed on the right side of the holder part 30.

[0078] 9(3), the display unit 20 is moved so that it overlaps with the mounting position on the main frame 11. During this process, the display unit 20 is moved so that the second flexible substrate 22 does not come out of the insertion hole 25.

[0079] Next, as shown in Fig. 9 (4), the display unit 20 is attached to the main frame 11. For example, the display unit 20 is fitted into a fitting groove provided in the main frame 11. The second flexible board 22 is also attached to the holder component 30. Specifically, one long side of the second flexible board 22 is inserted between the holding plate 31 and a floating prevention hook 47 provided on the rear side of the holder component 30. This allows the second flexible board 22 to be held in a state aligned with the rear side of the holder component 30 (holding plate 31).

[0080] 9(5), the second connector C2 provided on the second flexible substrate 22 is connected to the first connector C1 provided on the first flexible substrate 16. Here, the main frame 11 with the display unit 20 attached is inverted so that the display unit 20 is positioned downward, and the first flexible substrate 16 (first connector C1) is attached from above. Note that it is not necessary to invert the main frame 11.

[0081] Fig. 12 is a perspective view showing how the connectors are connected in the assembly process, showing the main frame 11 on which the display unit 20 and the holder part 30 are mounted, and the first flexible board 16 connected to the display unit 20, as viewed from the rear side.

[0082] The upper and lower views of Figure 12 show the states before and after connection of the first connector C1 and the second connector C2. Here, the first connector C1 is indicated by the dotted line area. The first flexible board 16 is configured as, for example, a flexible board and is arranged in a predetermined position along the rear side of the main frame 11 (plate portion 12). At this time, the first connector C1 is arranged in a connection position with the second connector C2.

[0083] 9(5), when connecting the first connector C1 and the second connector C2, pressure is applied to the first connector C1 from the rear side of the first flexible board 16. Therefore, the second connector C2 is pressed against the holder part 30. Even when pressure is applied from the rear side, the holder part 30 fixed to the main frame 11 holds the second connector C2 without coming off the main frame 11 because there are second hooks 44 that press against the rear side (second surface 11b) of the main frame 11.

[0084] In this way, the holder part 30 is configured so that, while fixed to the main frame 11, it will not come off the main frame 11 even if pressure is applied from the first connector C1 side to connect the first connector C1 and the second connector C2. This makes it possible to properly connect the first connector C1 and the second connector C2 even if the second connector C2 is placed in the connection position first.

[0085] Furthermore, the holder part 30 does not release the pressure for connecting the connector to the rear. That is, no force is applied from the rear side to the display 1 placed on the front side of the holder part 30 (the lower side in (5) of Figure 9). This makes it possible to reliably prevent damage to the display 1 or malfunctions, and allows the electronic device 100 to be assembled safely.

[0086] 13A to 13F are schematic diagrams showing an example of a process for replacing the display unit 20. Below, as an example of repairing the electronic device 100, a process for replacing the old display unit 20a shown in Fig. 13A with the new display unit 20b shown in Fig. 13F will be described.

[0087] First, as shown in Fig. 13A, the old display unit 20a to be replaced in the electronic device 100 is opened. This exposes the holder part 30 attached to the main unit 10. In this state, the holder part 30 is slid in the opposite direction to the insertion direction to remove it from the main unit 10. Then, the second flexible board 22 (second connector C2) of the old display unit 20a is removed from the main unit 10. This completes the removal of the old display unit 20a.

[0088] 13B, the first connector C1 is exposed from the opening 15. In this state, a new display unit 20b is prepared and the protective cover and other parts are removed to prepare it for installation.

[0089] When attaching a new display unit 20b, first, as shown in Fig. 13C, the second connector C2 (the area indicated by the dotted line in the figure) provided on the second flexible substrate 22 of the new display unit 20b is connected to the first connector C1. At this time, the reinforcing plate 23 of the second flexible substrate 22 is pressed from the front side, thereby connecting the second connector C2 to the first connector C1. Note that, because the support component 17 described with reference to Fig. 4 is disposed on the back side of the first connector C1, the first connector C1 will not move or deform due to pressure from the front side.

[0090] Next, as shown in Fig. 13D, the holder component 30 is inserted into the installation start position with the second connector C2 connected to the first connector C1. As shown in Fig. 6B, the width of the middle portion of the second flexible substrate 22 is slightly narrower than the width of the tip portion. This makes it less likely that the floating prevention hook 47 provided on the back side will interfere with the second flexible substrate 22 when the holder component 30 is inserted into the installation start position.

[0091] 13E, the holder part 30 is slid in the mounting direction (to the left in the figure) and mounted on the main unit 10 (main frame 11). This fixes the holder part 30 to the main frame 11. At this time, the tip of the second flexible board 22 is held between the anti-floating hook 47 and the holding plate.

[0092] After the holder part 30 is slid into the mounting position, the holder part 30 will not fall off from the main unit 10. Furthermore, the holder part 30 holds the second flexible substrate 22 with the second connector C2 attached to the first connector C1. Therefore, even if the second flexible substrate 22 is bent, the second connector C2 will not come off from the first connector C1. From another perspective, bending the second flexible substrate 22 will not cause the holder part 30 to come off due to the pressure applied to its tip. This makes it possible to proceed with the process without worrying about the second connector C2 coming off.

[0093] Once the holder part 30 is attached, the new display unit 20b is closed and attached to the main unit 10, as shown in Figure 13F. At this time, the second flexible board 22 is bent 180 degrees, but since it is held down by the holder part 30 as described above, the second connector C2 does not come loose. Once the new display unit 20b is attached to the main unit 10, the display unit 20 replacement operation is complete.

[0094] As described above, in the electronic device 100 according to this embodiment, the second connector C2 provided on the second flexible substrate 22 of the display unit 20 is connected to the first connector C1 exposed through the opening 15 of the main unit 10. At this time, the second flexible substrate 22 is held by the holder component 30, which covers at least a portion of the opening 15 and is detachably fixed to the main unit 10. This allows the second connector C2 to be held in an appropriate connection position above the opening 15, facilitating assembly, for example, even when the display unit 20 is first placed. Furthermore, when repairing the electronic device 100, the holder component 30 can be detached to facilitate the connection of the first connector C1 and the second connector C2, making it easy to remove or replace the main unit 10, for example. As a result, an electronic device 100 that is easy to assemble and repair can be realized.

[0095] In recent years, there has been a demand for the right to repair products (Right to Repair) to ensure that products can be used for a long period of time. Ecodesign regulations, etc., also call for the reduction of discarded parts. To meet these demands, it is important to design products with repair in mind. For example, electronic devices such as smartphones are designed so that either the display or the back panel can be removed to replace components, and parts can be replaced from either side.

[0096] For example, in an assembly method in which the display is attached last, a board-mounted connector for connecting to the display's FPC connector is provided exposed from the main frame. In this case, to prevent the connector from coming loose, a protective metal plate is used to secure the connector's connection point from the display side. The protective metal plate is, for example, a long metal member that is aligned with the connector, with one end hooked onto the main frame and the other end fixed with a screw. Fixing with a screw properly positions the metal protective metal plate and has the effect of stabilizing antenna performance.

[0097] On the other hand, the protective plate itself does not have the ability to hold itself or other components in place, and it easily comes off the main frame until it is screwed in. For this reason, when a general user assembles the device, they must perform precise work, such as screwing in the plate while being careful not to disconnect connectors or let the protective plate fall off. Furthermore, depending on the type of screw, a special screwdriver may be required, which could make repairs impossible.

[0098] For example, in an assembly method where the display is placed first and the back panel is attached last, replacing the display of the completed product requires removing all components other than the display. Therefore, while removing the back panel to replace the battery or other components requires fewer steps, the amount of work required to replace the display increases significantly.

[0099] It is also conceivable to drill holes in the mainframe to expose the board-mounted connector so that the display can be replaced on the finished product assembled using this method. In this case, the board-mounted connector would be connected from the rear side to the FPC connector of the display that was placed first during initial assembly, but there is no rigid component in the position where pressure from the rear side would be applied. This could result in pressure being applied to the display, potentially damaging it. It is also conceivable to use a protective metal plate as described above, but because the protective metal plate is primarily fixed with screws, depending on the fixation state and the strength of the metal plate, it may not have sufficient pressure strength, and the protective metal plate may come off when pressure is applied from the rear side.

[0100] In the electronic device 100 according to this embodiment, the holder part 30 is detachably fixed so as to cover the opening 15 provided in the main unit 10. The holder part 30 also holds the second flexible substrate 22 provided with the second connector C2 at the connection position between the first connector C1 on the main unit 10 side and the second connector C2 on the display unit 20 side.

[0101] In this way, the second flexible substrate 22 is held above the opening 15 by the strong holder component 30. This eliminates the need to select a component for mounting the second connector C2. For example, during initial assembly, in which the display unit 20 is placed first, it was necessary to use a rigid substrate or the like to support the second connector C2. In contrast, by providing the holder component 30, even when the second connector C2 is mounted on the second flexible substrate 22 as in this embodiment, it becomes possible to insert the first flexible substrate 16, such as a relay FPC, on which the first connector C1 is provided.

[0102] Furthermore, pressure applied to the second connector C2 from the rear side is received by the holder part 30 and does not affect the rear side of the holder part 30. This prevents unnecessary force from being applied to the display unit 20, reducing the risk of damage to the display 1.

[0103] Furthermore, by arranging a support component 17 such as a speaker box on the rear side of the first connector C1, it becomes possible to insert the second connector C2 into the first connector C1 from the front side. This makes it possible to open the display unit 20 and insert / remove the second connector C2, making it possible to replace only the display 1 (display unit 20) in the completed electronic device 100. This improves the efficiency of part replacement.

[0104] Furthermore, there is no limitation on the direction in which the first connector C1 and the second connector C2 are inserted or removed, which greatly improves the degree of freedom in the design and manufacture of the electronic device 100. For example, because the second connector C2 is held by the holder part 30 even during initial assembly, the connectors are not limited to being connected by hand, and it is also possible to introduce machine assembly using an automatic machine or the like.

[0105] Furthermore, the holder component 30 according to this embodiment is provided with a shape that embraces the main frame 11 while sliding. This structure allows the holder component 30 to be fixed to the main unit 10 (main frame 11) by itself, and also functions to hold the second flexible board 22. This ensures that the holder component 30 is strong enough to withstand pressure from both the front and back sides, and can withstand pressure when connecting the connectors. This also prevents the holder component 30 from falling off when attaching it to the main frame 11, improving work efficiency.

[0106] Furthermore, the electronic device 100 is assembled by placing the display unit 20 first and attaching the rear panel last. In this case, typically, the rear panel is opened and all components are removed before replacing the display unit 20. In contrast, in the present configuration with the holder component 30, the connector portion for the display unit 20 is exposed by opening the display unit 20 and removing the holder component 30. Therefore, after removing the old display unit 20, repairs can be completed by connecting the connector of the new display unit 20, attaching the holder component 30, and closing the new display unit 20.

[0107] Furthermore, there is no need to perform delicate screwing or other work to secure the holder component 30, nor is there a need to use specialized tools. Additionally, as described above, the risk of damage to other components is reduced, significantly reducing the difficulty of replacement work. This allows even general users to easily replace the display unit 20, even though the device is assembled from the rear panel side. As a result, it is possible to realize an electronic device that meets requirements such as the right to repair and eco-design regulations.

[0108] Other Embodiments The present technology is not limited to the above-described embodiments, and various other embodiments can be realized.

[0109] 14A and 14B are perspective views of another example of the holder part 30b as viewed from the front and rear, respectively. The holder part 30b shown in FIGS. 14A and 14B has different numbers of second hooks 44 for holding the rear surface (second surface 11b) of the main frame 11.

[0110] The holder part 30b has side surfaces 34 formed along the upper and lower edges of the holding plate 31. Each side surface 34 has a first hook 43 and a second hook 44 formed thereon. The first hook 43 is formed from the center of the outer surface 35 in the horizontal direction (X direction) to the right end in the figure. The second hook 44 is formed at the left end of the outer surface 35 in the horizontal direction (X direction) in the figure (the end on the side where the dowel portion 46 is formed).

[0111] In this way, even when only one pair of second hooks 44 is provided, it is possible to press the back surface (second surface 11b) of the main frame 11 along the upper and lower edges of the holding plate 31. For example, if there is not enough space to slide the hooks on the back surface of the main frame 11, the number of second hooks 44 may be reduced, as in the holder part 30b.

[0112] Fig. 15 is a perspective view showing another example of a holder part 30c. The holder part 30c shown in Fig. 15 is attached to the main frame 11 without sliding by utilizing the deflection of the first hook 43 and the second hook 44.

[0113] In the holder part 30c, an independent side surface portion 34 is formed for each hook. This makes each side surface portion 34 more elastically deformable, allowing each hook to bend. Here, a first hook 43 is formed in the center of the upper edge (or lower edge) of the holding plate 31, and second hooks 44 are formed on the left and right ends. Note that the main frame 11 does not have a notch or the like for passing the second hook 44 through.

[0114] When fitting the holder part 30c into the main frame 11 (opening 15), the holder part 30c is dropped into the opening 15 with the dowel portion 46 positioned directly above the dowel receiving portion 19. Specifically, by pushing the holder part 30c from the front side, the holder part 30c is pushed in until the first hook 43 contacts the front surface (first surface 11f) of the main frame 11.

[0115] During this process, the second hook 44 temporarily bends, but the bending is eliminated when the first hook 43 abuts against the main frame 11. As a result, the second hook 44 presses against the back surface (second surface 11b) of the main frame 11. Note that the back surface of the second hook 44 may be formed with an inclined surface that is pressed against the outer periphery of the opening 15 when each hook is fitted. This allows the second hook 44 to bend efficiently.

[0116] In this way, the holder part 30c can be attached to the main frame 11 without sliding. For example, in cases where it is not possible to ensure sufficient space for sliding the holder part 30c, by employing the holder part 30c, it is possible to minimize the space required for attaching and detaching the holder part 30c.

[0117] Fig. 16 is a perspective view showing another example of a holder part. Fig. 17 is a perspective view showing another example of a holder part. In the holder parts 30d and 30e shown in Figs. 16 and 17, a snap fit 60 (claw engagement mechanism) is used as a fixing mechanism to the main frame 11. The snap fit 60 provided on the holder parts 30d and 30e each includes a claw portion 61 that engages with the main unit 10 (main frame 11) and a release mechanism 62 that releases the engagement of the claw portion 61. Using the snap fit 60 provided with the release mechanism 62 makes it easier to remove the holder part.

[0118] The holder part 30d shown in FIG. 16 includes a holding plate 31, a U-shaped beam 63 having one end connected to the holding plate 31, a claw 61 provided at the tip of the beam 63, and a convex hook 64 provided on the opposite side of the holding plate 31 from the claw 61. In this case, the main unit 10 is formed with an engagement portion, which is a groove or through-hole into which the claw 61 and hook 64 of the holder part 30d fit. The holder part 30d is attached to the main unit 10 by first fitting the hook 64 and then fitting the claw 61. When the holder part 30d is attached, the tip of the beam 63 is pressed toward the holding plate 31 to release the engagement of the claw 61. In this manner, the U-shaped beam 63 functions as a release mechanism 62 in the holder part 30d.

[0119] 17 includes a holding plate 31, a claw portion 61 connected to the holding plate 31 and barbed on the front side, and a hook portion 64 provided on the rear side of the holding plate 31, opposite the claw portion 61. In this case, an engagement portion into which the claw portion 61 and hook portion 64 of the holder part 30e fit is formed in the main unit 10. The holder part 30e is attached to the main unit 10 by sliding. When the holder part 30e is attached, the engagement of the claw portion 61 is released by pressing the base of the claw portion 61. In this way, the release mechanism 62 in the holder part 30e utilizes the deflection of the holding plate 31 itself.

[0120] In addition, the method for attaching the holder part to the main unit 10 is not limited, and any fixing mechanism that detachably fixes the holder part to the main unit 10 may be used.

[0121] In the above embodiment, a configuration has been described in which the opening for exposing the first connector is provided in the main frame. However, this is not limiting, and the opening may be provided in a structural member other than the main frame. For example, the opening may be provided in a frame (subframe) other than the main frame, or in an internal case or cover provided separately from the frame. In this case, the holder component is detachably fixed to the structural member in which the opening is provided so as to cover at least a portion of the opening.

[0122] In the above embodiment, a display unit has been described as an example of a unit (second device unit) in which the second connector and flexible substrate are provided. The present technology can be applied to any unit constituting an electronic device. For example, when a rear panel unit is configured in which a rear panel and other components (such as a rear camera) are unitized, a holder component may be provided at a portion connecting the rear panel unit and the main unit. In addition, a holder component may be used at a portion connecting units inside the electronic device.

[0123] In the above embodiment, a smartphone has been described as an example of an electronic device, but the type of electronic device to which the present technology can be applied is not limited. The present technology can be applied to, for example, mobile devices such as tablet devices and portable music players, and wearable devices such as smartwatches. The present technology may also be applied to electronic devices such as notebook or desktop PCs, digital cameras, televisions, and audio equipment. The present technology can also be applied to any other electronic device.

[0124] It is also possible to combine at least two of the features of the present technology described above. That is, the various features described in each embodiment may be arbitrarily combined without distinguishing between the embodiments. Furthermore, the various effects described above are merely examples and are not intended to be limiting, and other effects may also be achieved.

[0125] In the present disclosure, the terms "same," "equal," "orthogonal," etc. are concepts that include "substantially the same," "substantially equal," "substantially orthogonal," etc. For example, they also include states that fall within a predetermined range (e.g., a range of ±10%) based on "completely the same," "completely equal," "completely orthogonal," etc.

[0126] The present technology may also be configured as follows: (1) An electronic device comprising: a first device unit having a first connector that is a board-to-board connector, a first connector board on which the first connector is provided, and an opening exposing a connection port of the first connector; a second device unit having a second connector connected to the first connector and a second connector board on which the second connector is provided; and a holder part that covers at least a part of the opening, is detachably fixed to the first device unit, and holds the second connector board so that the second connector is positioned at a connection position with the first connector. (2) The electronic device described in (1), wherein the first connector board and the second connector board are flexible boards. (3) The electronic device described in (1), wherein the first device unit has a frame in which the opening exposing the connection port of the first connector is formed, the first connector board is arranged along the frame, and the holder part is detachably fixed to the frame. (4) The electronic device described in (3), wherein the frame has a first surface facing the second equipment unit and a second surface opposite to the first surface, and the holder part is fixed to the frame from the first surface side.
