  FIG. 1 shows a support member 12 of the first embodiment. Further, FIG. 2 partially shows the assembly 16 in a state where the support member 12 is fixed to the chassis 14. The chassis 14 is an example of a fixing destination member. Further, FIG. 3 shows a computer 22 having a substrate 30 in which a heat sink 20 is attached to a substrate body 18 using the support member 12 from the back side. The computer 22 is an example of an information processing device.

  As shown in FIG. 4, the computer 22 has a front cover 24 and a rear cover 26. Between the front cover 24 and the rear cover 26, a display 28, a chassis 14, and a substrate 30 are arranged in this order from the front cover 24 side, and are attached to predetermined positions.

  As also shown in FIGS. 10A and 10B, an element 34 such as a CPU is mounted on the substrate body 18 via a socket 32. In the element 34, the heat sink 20 for heat dissipation is disposed on the opposite surface of the substrate body 18. When attaching the heat sink 20 to the substrate body 18, the support member 12 is disposed so as to sandwich the substrate body 18, the socket 32, and the element 34 between the support member 12 and the heat sink 20. Then, the mounting screw 36 is inserted through the heat sink 20 and the substrate body 18 and screwed into the female screw 38 (see FIG. 10B) of the support member 12, and the heat sink 20 is fixed to the substrate body 18. The support member 12 suppresses the bending of the substrate body 18 by supporting the substrate body 18 to which the heat sink 20 is attached from the opposite side of the heat sink 20. In the present embodiment, the substrate body 18 is an example of a support member.

  As shown in FIGS. 1 and 2, the support member 12 has a support main body 40. In the illustrated example, the support main body 40 is formed in a rectangular frame shape in plan view (the direction shown in FIG. 2). The support main body 40 is a part that makes surface contact with the substrate main body 18 and suppresses bending of the substrate main body 18. Hereinafter, for convenience, the four sides of the support main body 40 will be described separately as a set of one facing side 42A and a set of the other facing side 42B.

  A plurality of (three in the illustrated example) arm portions 44 extend from the outer edge of the support main body portion 40. A guide convex portion 45 that protrudes in the same direction as a positioning convex portion 48 to be described later is formed at the tip portion of each arm portion 44. On the other hand, the guide slot 47 corresponding to each guide convex part 45 is formed in the chassis 14. When the support member 12 is fixed to the chassis 14, the guide protrusion 45 can be accommodated in the guide slot 47 and can be slid in the longitudinal direction of the guide slot 47.

  A female screw 38 is formed on each of the guide convex portions 45. A mounting screw 36 inserted into the substrate body 18 from the heat sink 20 side is screwed into the female screw 38, and the heat sink 20 is attached to the substrate body 18.

  A substantially U-shaped notch is formed in each of the opposing sides 42A of the support main body 40, and a positioning spring piece 46 is formed inside the notch. The positioning spring piece 46 is bent and deformed like a leaf spring.

  At the tip of the positioning spring piece 46, a positioning convex portion 48 protruding in a truncated cone shape is formed. The protruding direction of the positioning convex portion 48 is a direction toward the chassis 14 when the support member 12 is fixed to the chassis 14. This direction is also a direction away from the substrate body 18 with the heat sink 20 attached to the substrate body 18 using the support member 12.

  As shown in detail in FIG. 5, a positioning hole 50 is formed in the chassis 14. When the support member 12 is in a predetermined position with respect to the chassis 14, the positioning protrusions 48 are fitted into the positioning holes 50. Thereby, the support member 12 is positioned with respect to the chassis 14. The predetermined position is a position where the support member 12 supports the substrate body 18 with the heat sink 20 attached to the substrate body 18. In other words, this support position is an original position from the viewpoint that the support member 12 supports other members.

  In the illustrated example, of the two positioning holes 50, one positioning hole 50A has a perfect circle shape in a plan view so that high positioning accuracy can be obtained. On the other hand, the other positioning hole 50B has an oval shape and can absorb a dimensional error between the support member 12 and the chassis 14.

  A substantially U-shaped notch is formed in each of the other opposing sides 42B of the support main body 40, and a fixed spring piece 52 is formed inside the notch. As shown in FIGS. 8A, 9A, and 10A, the fixed spring piece 52 is bent and deformed into a leaf spring shape.

  An engaging portion 54 is further extended on the distal end side of the fixed spring piece 52 in a direction orthogonal to the extending direction of the fixed spring piece 52, and a pressed portion 56 is extended in the opposite direction of the engaging portion 54. Has been issued.

  As can be seen from FIG. 7A, the extending direction and the position of the engaging portion 54 are the direction and the position inserted into the fixing hole 58 formed in the chassis 14 when the support member 12 is fixed to the chassis 14. . The assembly 16 has a structure having the chassis 14 and the support member 12 fixed to the chassis 14 by engaging the engaging portion 54 with the fixing hole 58.

  When the fixed spring piece 52 is bent and deformed, the engaging portion 54 engages with the fixing hole 58 (see FIG. 7A), and the disengaged disengaged position (see FIG. 10A). Move between.

  A tapered surface 54T is formed on the distal end side of the engaging portion 54, and an engaging surface 54K is formed on the opposite side. On the other hand, a fixing hole 58 is formed in the chassis 14. The support member 12 is fixed to the chassis 14 by the engagement surface 54 </ b> K engaging with the edge of the fixing hole 58 from the opposite side of the support main body 40.

  When the engagement portion 54 is engaged with the fixing hole 58, when the tapered surface 54T hits the edge of the fixing hole 58, the fixing spring piece 52 is slightly bent and the engagement portion 54 is bent. The front end side of the fixed hole 58 enters the fixing hole 58.

  As shown in detail in FIGS. 8A, 9A, and 10A, the pressed portion 56 is pressed by the substrate body 18 when the heat sink 20 is attached to the substrate body 18 by the support member 12, and the fixed spring piece 52 It is formed at a position where the deflection is increased. When the bending of the fixed spring piece 52 increases as described above, the engaging portion moves to the disengagement position, and the engagement with the fixing hole 58 is released.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 4, the support member 12 and the chassis 14 are formed separately. In the main temple family, as shown in FIGS. 7A and 7B, the engaging portion 54 is engaged with the edge portion of the fixed hole portion 58 in a state where the positioning convex portion 48 is fitted and positioned in the positioning hole portion 50. be able to. As a result, the chassis 14 and the support member 12 can be fixed and handled as an assembly 16 integrally. For example, it is possible to carry the chassis 14 and the support member 12 together to the assembly factory of the computer 22.

  In addition, since it is not necessary to fix the chassis 14 and the support member 12 using a fixing member (for example, a fixing adhesive tape), the number of work steps can be reduced and the cost can be reduced. It is.

  Furthermore, since the chassis 14 and the support member 12 can be transported integrally, the transportation cost can be reduced as compared with a structure in which the chassis 14 and the support member are separate.

  When the support member 12 is fixed to the chassis 14, the guide convex portion 45 is first accommodated in the guide long hole 47 as shown in FIG. 6. Next, the support member 12 can be fixed to the chassis 14 by sliding the support member 12 in the arrow S1 direction. In a state where the positioning convex portion 48 is not accommodated in the positioning hole 50, the positioning spring piece 46 is bent to the opposite side of the chassis 14, but when the positioning convex portion 48 is accommodated in the positioning hole 50, this bending is performed. Is resolved.

  When the computer 22 is manufactured, as shown in FIGS. 8A and 8B, the mounting screw 36 is inserted into the board body 18 from the heat sink 20 side using the support member 12 fixed to the chassis 14, thereby supporting the member. Screw into the twelve female threads 38. The support member 12 is fixed to the chassis 14 at a position that supports the substrate body 18 with the heat sink 20 attached to the substrate body 18. For this reason, the process of moving the support member 12 is unnecessary, and the number of work steps is reduced.

  In addition, since the fixing member described above is not used, it is not necessary to remove the fixing member while supporting the substrate body 18 using the support member 12. Man-hours and costs for disposing of fixing members can be reduced.

  As the attachment screw 36 is further screwed in, the substrate body 18 and the support member 12 are relatively close to each other. Since the pressed portion 56 is pressed by the substrate body 18 and the fixed spring piece 52 is bent, the engaging portion 54 moves from the engaging position toward the disengaging position.

  As shown in detail in FIGS. 9A and 9B, when the substrate body 18 and the support member 12 come into contact with each other, the substrate body 18 is supported by the support member 12, and the heat sink 20 is attached to the substrate body 18. Also in the assembly process, the computer 22 does not require a process of removing and moving the support member 12 from the chassis 14 in the assembly process, and the number of work steps during assembly is reduced.

  In addition, in a state where the substrate body 18 and the support member 12 are in contact with each other, the engaging portion 54 reaches the disengagement position, and the engagement with the fixing hole 58 is released. Accordingly, as shown in FIGS. 10A and 10B, the substrate body 18, the heat sink 20, and the support member 12 (which are integrally attached by the attachment screws 36) can be removed from the chassis 14. For example, when removing the board 30 from the computer 22, the board 30 is released from the chassis 14, so that the removal work is easy.

  In particular, in the present embodiment, the pressed portion 56 is pushed by the substrate body 18 in a state where the substrate body 18 and the support member 12 are in contact, and the engaging portion 54 reaches the engagement release position. Since the operation for releasing the engagement of the engaging portion 54 with the fixing hole portion 58 is unnecessary, the workability when removing the substrate 30 from the computer 22 is excellent.

  Further, since the engaging portion 54 is a portion that can be moved between the engaging position and the engaging releasing position, an excessive releasing force is not required for releasing the engagement, and when the engaging portion 54 is released. Can also be prevented.

  In addition, the heat sink 20 is kept in contact with the element 34 with the substrate 30 removed from the computer 22. If the heat sink 20 is separated from the element 34, it is necessary to apply grease or the like to the contact surface when reassembling, but in this embodiment, it is not necessary to apply grease and the workability is excellent.

  In the above description, the structure in which the engaging portion 54 moves from the engaging position to the disengaging position when the pressed portion 56 is pressed by the substrate body 18 is described. However, for example, in the structure in which the hole is formed in the portion corresponding to the pressed portion 56 of the substrate body 18, the substrate body 18 does not press the pressed portion 56. In such a case, the operator may press the pressed portion 56 with a tool or the like to bend the fixed spring piece 52 and move the engaging portion 54 from the engaging position to the disengaging position. .

  In the above description, as an example of the fixing portion, the engaging portion 54 that engages with the edge of the fixing hole portion 58 of the chassis 14 is described, but the fixing portion is not limited to the engaging portion 54. For example, a surface (facing surface) facing a part of the chassis 14 may be formed at the tip of the fixed spring piece 52, and the facing surface and the facing portion of the chassis 14 may be bonded with a double-sided adhesive tape or the like. In this case, in order to release the adhesion of the double-sided adhesive tape, the fixing spring piece 52 may be bent so that the opposing surface is separated. Further, if the double-sided adhesive tape remains adhered to either the chassis 14 or the support member 12 even after the adhesion is released, the disposal is not necessary. However, this structure requires a double-sided adhesive tape. Further, it may be difficult to release the adhesion using the movement of the fixed spring piece 52 when the pressed portion 56 is pressed against the substrate body 18 depending on the position of the double-sided adhesive tape. When the engaging portion 54 is used as the fixing portion as in the above-described embodiment, the number of parts does not increase, and when the pressed portion 56 is pressed against the board body 18, reliable engagement release (fixing release) ) Is feasible.

  In the above description, the engaging portion 54 (fixed portion) is provided with the fixed spring piece 52 that is cantilevered from the support main body 40. The engaging portion 54 may be formed. As described above, when the engaging portion 54 is formed at the tip of the fixed spring piece 52, the engaging portion 54 can be engaged with the edge of the fixed hole portion 58 by using the spring force of the fixed spring piece 52. More reliable engagement is possible. Further, the engagement can be released using the bending of the fixed spring piece 52.

  In addition, the support member 12 can be fixed to the chassis 14 by engaging the engaging portion 54 (fixing portion) with a simple structure in which the fixing hole 58 is formed as the chassis 14 (fixing destination member).

  In the above description, the positioning convex portion 48 is used as the positioning portion, but the positioning portion is not limited to the positioning convex portion 48. For example, a structure may be employed in which a plurality of walls are formed in the support member 12 and the support member 12 is positioned on the chassis 14 by abutting the walls against a part of the chassis 14. As described above, when the positioning convex portion 48 is formed as the positioning portion, the supporting member 12 can be positioned on the chassis 14 by fitting the positioning convex portion 48 into the positioning hole portion 50 of the chassis 14 with a simple structure. Is possible.

  In the above example, the positioning protrusion 48 (positioning portion) is provided with the positioning spring piece 46 that is cantilevered from the support main body portion 40. The positioning convex part 48 may be formed. As described above, when the positioning convex portion 48 is formed at the tip of the positioning spring piece 46, the positioning convex portion 48 can be fitted into the positioning hole portion 50 by using the spring force of the positioning spring piece 46, so that more reliable. Positioning is possible.

  In addition, as the chassis 14 (fixed tip member), the support member 12 can be positioned on the chassis 14 by fitting the positioning hole 50 (positioning portion) with a simple structure in which the positioning hole 50 is formed.

  In the above description, the support member 12 having a structure for supporting the substrate body 18 with the element 34 sandwiched between the substrate body 18 and the heat sink 20 has been described as an example of the support member. However, the support member is not limited thereto. . For example, in a structure in which a connection member such as a connector is attached to the substrate body 18, a support member that supports the substrate body 18 from the opposite side of the attachment portion of the connection member may be used.

  Further, the supported member is not limited to the substrate body 18. For example, examples of the supported member for the connecting member such as the connector described above include a casing of the information processing apparatus, a plate-like member inside the information processing apparatus, and the like.

  As the information processing apparatus, the computer 22 in which the display 28 is integrated is described above, but the display may be a separate computer. Furthermore, the information processing apparatus is not limited to a computer, and may be, for example, a processing apparatus or recording / reproducing apparatus for electronic information (including video / image / audio data).

  The embodiments of the technology disclosed in the present application have been described above. However, the technology disclosed in the present application is not limited to the above, and can be variously modified and implemented in a range not departing from the gist of the present invention.
