DETAILED DESCRIPTION OF THE INVENTION
[0013] Embodiments of the present disclosure will be described in detail with reference to the drawings.
[0014] [Embodiment] An example of use of the electronic device 1 will be described with reference to FIGS. 1 and 2. The electronic device 1 shown in FIGS. 1 and 2 includes a card 10, a housing 11, and a fastener 12. FIG. 1 is a perspective view illustrating an example of inserting the card 10 into the housing 11. In the example illustrated in FIG. 1, the card 10 is inserted into the housing 11 in the direction of arrow A. That is, arrow A is the insertion direction of the card 10. The card 10 is inserted into the housing 11 in the direction of arrow A, and is then housed in the housing 11. The card 10 may also be removable from the housing 11. For example, a person who removes the card 10 may be able to remove the card 10 in the direction opposite to the arrow A. In the example illustrated in FIG. 1, multiple cards 10 are housed in the housing 11. Here, in the example illustrated in FIG. 1, the fastener 12 can be attached to all of the cards 10 housed in the housing 11. Some of the cards 10 housed in the housing 11 may be configured to be able to have the fastener 12 attached. In other words, some of the cards 10 housed in the housing 11 may be configured such that the fastener 12 cannot be attached to them.
[0015] FIG. 2 is a perspective view showing an example of how fastener 12 is attached to housing 11 and card 10 housed in housing 11. In the example shown in FIG. 2, fastener 12 is attached to housing 11 and card 10 in the direction of arrow B. The direction of arrow B is the attachment direction of fastener 12. Fastener 12 may be detachable from housing 11 and card 10. A person removing the fastener may be able to remove fastener 12 in the direction opposite to arrow B. Here, direction A and direction B may be the same direction.
[0016] The following describes each component included in the electronic device 1. The electronic device 1 includes a card 10, a housing 11, and a fastener 12. The electronic device 1 may also include a screw 13.
[0017] The card 10 includes a heat-generating component 106. The heat-generating component 106 is, for example, an electronic component. By housing the card 10 in the housing 11, it becomes possible to improve the performance and functionality of the information processing device. Specific examples of the card 10 include a graphics board and an interface card, but the card 10 is not limited to these.
[0018] An example of the structure of the card 10 will be described with reference to Figures 3 and 4. Figure 3 is a perspective view showing an example of the structure of the card 10. Figure 4 is a side view showing an example of the structure of the card 10.
[0019] The card 10 includes, for example, a substrate 101, a heat sink 102, and a panel 103. A heat-generating component 106 is mounted on the substrate 101. In the card 10, the heat-generating component 106 mounted on the substrate 101 and the heat sink 102 are in contact with each other. The heat sink 102 and the panel 103 are connected to each other. A connector 105 is also provided on the substrate 101. The connector 105 provided on the substrate 101 is connected to a connector provided on the housing 11. The housing 11 will be described later. By connecting the connector 105 provided on the substrate 101 to the connector provided on the housing 11, the electronic device 1 can achieve improved performance and functionality as an information processing device.
[0020] A hole 104 is formed in the panel 103 of the card 10. When the card 10 is housed in the housing 11, the hole 104 in the card 10 faces the same direction as the opening of the hole 111 in the housing 11. In other words, when the card 10 is housed in the housing 11, the opening of the hole 104 in the card 10 and the opening of the hole 111 in the housing 11 face the same direction. The hole 104 in the card 10 may be formed so that the fastener 12 can be inserted from the insertion side of the card 10 when the card 10 is housed in the housing 11. The shape of the opening of the hole 104 in the card 10 is, for example, rectangular. The shape of the opening of the hole 104 is not limited to this. The shape of the opening of the hole 104 may correspond to the shape of a protrusion 121 of the fastener 12, which will be described later.
[0021] Furthermore, the structure of card 10 is not limited to this. Card 10 may have any structure as long as it includes heat-generating component 106 and hole 104.
[0022] The housing 11 can accommodate the card 10. An opening is formed on one side of the housing 11. The card 10 is inserted and removed through the opening of the housing 11. A connector is provided on the inside of the side of the housing 11 opposite the opening. The connector provided on the housing 11 is connected to the connector 105 of the card 10 described above. In the example of use shown in FIG. 1, six cards 10 can be accommodated in the housing 11. The number of cards 10 that can be accommodated in the housing 11 is not limited to this.
[0023] The housing 11 is provided with a hole 111. When the card 10 is housed in the housing 11, the hole 111 faces the same direction as the opening of the hole 104 in the card 10. In other words, when the card 10 is housed in the housing 11, the opening of the hole 104 in the card 10 and the opening of the hole 111 in the housing 11 face the same direction. The hole 111 in the housing 11 may be provided so that the fastener 12 can be inserted from the same direction as the card 10 was inserted when the card 10 is housed in the housing 11. The shape of the opening of the hole 111 in the housing 11 is, for example, rectangular. The shape of the opening of the hole 111 is not limited to this.
[0024] Next, with reference to FIG. 5, an example of the structure of fastener 12 will be described in detail. FIG. 5 is a side view showing an example of the structure of fastener 12. Fastener 12 has two protrusions 121. One of protrusions 121 can be inserted into hole 104 provided in card 10 when card 10 is housed in housing 11. The other protrusion 121 can be inserted into hole 111 provided in housing 11 when card 10 is housed in housing 11. In other words, fastener 12 is a component that can fasten card 10 and housing 11. The distance between the opposing sides of two protrusions 121 is shorter at the base of protrusions 121 than at the tip of protrusions 121. The distance between the opposing sides of two protrusions 121 may also be continuously shorter.
[0025] Here, the fastener 12 shown in Fig. 5 has a shape in which the tip is tapered relative to the base. As shown in Fig. 5, the two protrusions 121 may each have an inclination on the side where the protrusions 121 face each other. Furthermore, the side of the two protrusions 121 opposite the side where the protrusions 121 face each other may be a straight line. Here, the straight line does not have to be a strict straight line.
[0026] The structure of fastener 12 is not limited to this. Fastener 12 is provided with two protrusions 121, and it is sufficient that the distance between the opposing sides of two protrusions 121 is shorter at the base of protrusions 121 than at the tip of protrusions 121.
[0027] 6 to 9, a detailed description will be given of how fastener 12 is attached to card 10 and housing 11. FIG. 6 is a cross-sectional view showing an example of the structure of electronic device 1. In FIG. 6, card 10 is housed in housing 11. Also, FIGS. 7 to 9 are enlarged views of the periphery of the portion where fastener 12 is attached in the cross-sectional view showing the example of the structure of electronic device 1 shown in FIG. 6. FIGS. 7 to 9 are enlarged views showing an example of how fastener 12 is attached to card 10 and housing 11.
[0028] Fig. 7 shows the state before fastener 12 is attached to card 10 and housing 11. Fig. 8 shows the state in which fastener 12 is in the process of being attached to card 10 and housing 11. Fig. 9 shows the state in which fastener 12 has been attached to card 10 and housing 11. Fastener 12 is attached in the direction of arrow B shown in Figs. 7 to 9. Two protrusions 121 provided on fastener 12 are inserted into holes 104 provided in card 10 and holes 111 provided in housing 11, respectively.
[0029] Here, the electronic device 1 may include a screw 13. The screw 13 can attach the fastener 12 to the electronic device 1. The fastener 12 and the housing 11 have screw holes 131 at corresponding positions, respectively. The screw 13 is inserted into the screw holes 131 provided in the fastener 12 and the housing 11. As a result, the fastener 12 is attached to the housing 11 and the card 10 by the screw 13. An existing screw can be used as the screw 13. Referring again to FIGS. 7 to 9, the fastener 12 is attached by the screw 13.
[0030] Before the fastener 12 is attached to the card 10 and the housing 11, there may be a gap between the card 10 and the housing 11. Referring to FIG. 7, there is a gap between the card 10 and the housing 11. When the card 10 is inserted into the housing 11, a gap may be provided between the card 10 and the housing 11 to allow the card 10 to move. In other words, the gap between the card 10 and the housing 11 allows the card 10 to be inserted into the housing 11. Then, as shown in FIG. 8, the fastener 12 is inserted in the direction of arrow B and attached by the screw 13. As a result, as shown in FIG. 9, the fastener 12 is attached to the card 10 and the housing 11 by the screw 13.
[0031] In FIG. 9 , attaching fastener 12 to card 10 and housing 11 brings card 10 and housing 11 into contact with each other. The distance between the opposing sides of two protrusions 121 on fastener 12 is shorter at the base of protrusions 121 than at the tip of protrusions 121. Therefore, during the process of inserting fastener 12, a force acts in the direction of arrow C shown in FIG. 9 . Furthermore, when the distance between the opposing sides of two protrusions 121 continuously decreases, the gap between card 10 and housing 11 continuously decreases. As a result, card 10 and housing 11 come into contact with each other. In other words, when two protrusions are inserted into holes in the housing and a card, respectively, at least a portion of the surface of the card and the surface of the housing located between the two protrusions can come into contact with each other.
[0032] Here, referring to FIG. 10 , the flow of heat in the electronic device 1 when the card 10 and the housing 11 are in contact with each other will be described. FIG. 10 is a cross-sectional view showing an example of the heat flow in the electronic device 1. In FIG. 10 , the flow of heat generated by the heat-generating component 106 is indicated by arrows. Referring to FIG. 10 , the heat-generating component 106 mounted on the substrate 101 is in contact with the heat sink 102. Therefore, heat generated by the heat-generating component 106 is transferred from the heat sink 102 of the card 10 to the bottom surface of the housing 11. The heat generated by the heat-generating component 106 is then dissipated from a heat dissipation surface (not shown) provided on the bottom surface of the housing 11. In this case, the contact between the card 10 and the housing 11 enables more efficient heat dissipation than when there is a gap between the card 10 and the housing 11. Here, the card 10 and the housing 11 do not need to be in complete contact with each other. For example, as long as a portion of the card 10 is in contact with the housing 11, other portions of the card 10 do not need to be in contact with the housing 11.
[0033] The method for attaching fastener 12 to card 10 and housing 11 does not have to be by screws 13. In other words, electronic device 1 does not have to include screws 13. In electronic device 1, fastener 12 may be attached by a force other than screws 13. For example, fastener 12 may be attached by human force. In other words, a person may attach fastener 12 by pushing it in in the direction of arrow B shown in FIG. 7. Fastener 12 may also be hammered in with a hammer. For example, a person may use a hammer to hammer fastener 12 in. The tool used to hammer in fastener 12 is not limited to a hammer.
[0034] In the above description, the case where one hole 111 is provided in the housing 11 has been described. The number of holes provided in the housing 11 is not limited to one. A plurality of holes 111 may be provided in the housing 11 so that the holes 111 can be selected. For example, of the plurality of holes 111, a hole 111 corresponding to the size of the fastener 12, the shape of the card, etc. may be used. A person attaching the fastener 12 can select a hole 111 corresponding to the size of the fastener 12, the shape of the card, etc. Furthermore, the number of holes 104 provided in the card 10 is not limited to one.
[0035] In this embodiment, electronic device 1 includes card 10, housing 11, and fastener 12. Card 10 has heat-generating component 106 and is provided with hole 104. Housing 11 is capable of accommodating card 10 and is provided with hole 111. Fastener 12 is provided with two protrusions 121. The distance between the opposing sides of two protrusions 121 is shorter at the base of protrusions 121 than at the tip of protrusions 121. By attaching fastener 12 in which the distance between the opposing sides of protrusions 121 is shorter at the base of protrusions 121 than at the tip of protrusions 121, card 10 and housing 11 come into contact. As a result, heat dissipation efficiency in electronic device 1 can be improved.
[0036] To accommodate the card 10 in the housing 11, the card 10 needs to be inserted with a rocking motion. For this reason, there may be a gap between the card 10 and the housing 11. However, in the electronic device 1, if the contact between the housing 11 and the card 10 is insufficient, the heat generated in the card 10 may not be sufficiently dissipated. Therefore, attaching the fastener 12 brings the card 10 into contact with the housing 11. The heat generated in the card 10 can be efficiently dissipated to the housing 11. As a result, the heat dissipation efficiency of the electronic device 1 can be improved.
[0037] In the electronic device 1 of this embodiment, when the card 10 is housed in the housing 11, the hole 104 of the card 10 and the hole 111 of the housing 11 are arranged so that the fastener 12 can be inserted from the insertion side of the card 10. For example, a person attaching the fastener 12 can attach the fastener 12 from the same direction as the insertion direction of the card 10. This ensures ease of operation when mounting the card 10 in the electronic device 1.
[0038] For example, a case will be described where the direction in which card 10 is inserted differs from the direction in which fastener 12 is attached. In this case, the person who inserted card 10 may change the orientation of card 10 relative to electronic device 1 before attaching fastener 12. In other words, this may be time-consuming for the person inserting card 10. On the other hand, if the direction in which card 10 is inserted and the direction in which fastener 12 is attached are the same, it is possible to reduce the time and effort required of the person inserting card 10. In other words, it is possible to ensure ease of installation of card 10 in electronic device 1.
[0039] In the electronic device 1 of this embodiment, the distance between the two protrusions 121 on the opposing sides of the protrusions 121 continuously decreases. For example, the two protrusions 121 on the fastener 12 may be shaped so that the protrusions 121 are inclined from their tips to their bases on the opposing sides. When the distance between the protrusions 121 on the opposing sides continuously decreases, the gap between the card 10 and the housing 11 continuously decreases during the process of attaching the fastener 12 to the card 10 and the housing 11. This allows the person attaching the fastener 12 to smoothly attach the fastener 12. For example, when the protrusions 121 on the fastener 12 have a structure in which the thickness gradually increases from the tip to the base, it may be more difficult to attach the fastener 12 than when the distance between the protrusions 121 on the opposing sides continuously decreases. However, when the distance between the protrusions 121 on the opposing sides continuously decreases, it may be easier to attach and remove the fastener 12, for example.
[0040] In the electronic device 1 of this embodiment, screw holes 131 are provided in corresponding positions on the fastener 12 and the housing 11, and the fastener 12 is attached to the housing 11 and the card 10 with screws 13. When the fastener 12 is attached with screws 13, for example, a person removing the fastener 12 can also remove the fastener 12 by removing the screws 13. For example, the card 10 may be removed as needed. Therefore, it may be desirable for the fastener 12 to be easily attached and detached. Therefore, by attaching the fastener 12 to the housing 11 and the card 10 with screws 13, it becomes possible to easily attach and detach the fastener 12.
[0041] In the electronic device 1 of this embodiment, the two protrusions 121 are linear on the side opposite to the side where the protrusions 121 face each other. The two protrusions 121 are inserted into a hole 104 provided in the card 10 and a hole 111 provided in the housing 11, respectively. At this time, for example, if a slope is provided on the side opposite to the side where the protrusions 121 face each other and ... is linear, the size of the hole may be smaller than in a case where a slope is provided on both the side where the protrusions 121 face each other and the side opposite to the side where the protrusions 121 face each other. In other words, by having a straight line on the side opposite to the side where the protrusions 121 face each other, it may be possible to reduce the size of the hole.
[0042] Although the present disclosure has been described above with reference to the embodiments, the present disclosure is not limited to the above-described embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure. Furthermore, the configurations in the respective embodiments can be combined with each other without departing from the scope of the present disclosure.
