[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present disclosure will be described in detail with reference to the drawings.

[0014] [Embodiment] An example of the use of the electronic device 1 will be described with reference to FIG. 1 and FIG. 2. The electronic device 1, the example of which is shown in FIG. 1 and FIG. 2, includes a card 10, a housing 11, and a fastener 12. FIG. 1 is a perspective view showing an example of the manner in which the card 10 is inserted into the housing 11. In the example shown in FIG. 1, the card 10 is inserted into the housing 11 in the direction of the arrow A. That is, the arrow A is the insertion direction of the card 10. The card 10 is inserted into the housing 11 in the direction of the arrow A, and is then housed in the housing 11. The card 10 may be removable from the housing 11. For example, a person who pulls out the card 10 may be able to pull out the card 10 in the direction opposite to the arrow A. In the example shown in FIG. 1, a plurality of cards 10 are housed in the housing 11. Here, in the example shown 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] 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 removable 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] A description will now be given of 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. The card 10 is housed in a housing 11, which makes it possible to improve the performance and functions of the information processing device. Specific examples of the card 10 include a graphics board and an interface card. 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 the example of the structure of the card 10. Figure 4 is a side view showing the 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. The substrate 101 is also provided with a connector 105. The connector 105 mounted on the substrate 101 is connected to a connector mounted on the housing 11. The housing 11 will be described later. By connecting the connector 105 mounted on the substrate 101 to the connector mounted on the housing 11, the electronic device 1 can realize improved performance and functions of an information processing device.

[0020] A hole 104 is provided in the panel 103 of the card 10. The hole 104 provided in the card 10 faces the same direction as the opening of the hole 111 provided in the housing 11 when the card 10 is housed in the housing 11. In other words, when the card 10 is housed in the housing 11, the opening of the hole 104 provided in the card 10 and the opening of the hole 111 provided in the housing 11 face the same direction. The hole 104 provided in the card 10 may be provided 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 provided in the card 10 is, for example, a rectangle. 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 described later.

[0021] Furthermore, the structure of card 10 is not limited to this. Card 10 only needs to include 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. The hole 111 provided in the housing 11 faces the same direction as the opening of the hole 104 provided in the card 10 when the card 10 is housed in the housing 11. In other words, when the card 10 is housed in the housing 11, the opening of the hole 104 provided in the card 10 and the opening of the hole 111 provided in the housing 11 face the same direction. The hole 111 provided in the housing 11 may be provided so that the fastener 12 can be inserted from the direction in which the card 10 is inserted when the card 10 is housed in the housing 11. The shape of the opening of the hole 111 provided in the housing 11 is, for example, a rectangle. The shape of the opening of the hole 111 is not limited to this.

[0024] Next, referring to FIG. 5, an example of the structure of the fastener 12 will be described in detail. FIG. 5 is a side view showing an example of the structure of the fastener 12. The fastener 12 is provided with two protrusions 121. One of the protrusions 121 can be inserted into a hole 104 provided in the card 10 when the card 10 is housed in the housing 11. The other protrusion 121 can be inserted into a hole 111 provided in the housing 11 when the card 10 is housed in the housing 11. That is, the fastener 12 is a component capable of fastening the card 10 and the housing 11. The distance between the two protrusions 121 on the sides where the protrusions 121 face each other is shorter at the base of the protrusions 121 than at the tip of the protrusions 121. The distance between the two protrusions 121 on the sides where the protrusions 121 face each other may be continuously shorter.

[0025] Here, the fastener 12, an example of which is shown in Fig. 5, has a shape in which the tip is narrower than the base. As shown in an example in Fig. 5, the two protrusions 121 may each have an inclination on the side where the protrusions 121 face each other. Also, 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 the distance between the opposing sides of two protrusions 121 may be shorter at the base of protrusions 121 than at the tip of protrusions 121.

[0027] With reference to Fig. 6 to Fig. 9, a state in which fastener 12 is attached to card 10 and housing 11 will be described in detail. 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. Figs. 7 to 9 are enlarged views of the periphery of a 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 the state in which 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 on fastener 12 are inserted into hole 104 in card 10 and hole 111 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 are provided with 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 is used as the screw 13. Referring again to FIG. 7 to FIG. 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 accommodated in 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 the 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, the fastener 12 is attached to the card 10 and the housing 11, so that the card 10 and the housing 11 come into contact with each other. In the two protrusions 121 provided on the fastener 12, the distance between the sides where the protrusions 121 face each other is shorter at the base of the protrusions 121 than at the tip of the protrusions 121. Therefore, in the process of inserting the fastener 12, a force acts in the direction of the arrow C shown in FIG. 9. Also, when the distance between the sides where the protrusions 121 face each other becomes continuously shorter, the gap between the card 10 and the housing 11 becomes continuously smaller. As a result, the card 10 comes into contact with the housing 11. In other words, when the two protrusions are inserted into the holes provided in the housing and the holes provided in the card, at least a part 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 flow of heat 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 board 101 is in contact with the heat sink 102. Therefore, the 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. Then, the heat generated by the heat generating component 106 is dissipated from a heat dissipation surface (not shown) provided on the bottom surface of the housing 11. At this time, since the card 10 and the housing 11 are in contact with each other, more efficient heat dissipation can be realized 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, if a part of the card 10 is in contact with the housing 11, the other part of the card 10 does not need to be in contact with the housing 11.

[0033] The method of 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, fastener 12 may be attached by a person pushing it in in the direction of arrow B shown in FIG. 7. Fastener 12 may also be hammered in by a hammer. For example, a person may use a hammer to hammer fastener 12 in. The tool used to hammer fastener 12 in is not limited to a hammer.

[0034] In the above description, the case where the housing 11 has one hole 111 has been described. The number of holes provided in the housing 11 is not limited to one. The housing 11 may have a plurality of selectable holes 111. For example, of the plurality of holes 111, a hole 111 according 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 according 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, the electronic device 1 includes a card 10, a housing 11, and a fastener 12. The card 10 includes a heat generating component 106 and is provided with a hole 104. The housing 11 is capable of housing the card 10 and is provided with a hole 111. The fastener 12 is provided with two protrusions 121. The distance between the two protrusions 121 on the fastener 12 is shorter at the base of the protrusions 121 than at the tip of the protrusions 121. By attaching the fastener 12 in which the distance between the protrusions 121 on the side where the protrusions 121 face each other is shorter at the base of the protrusions 121 than at the tip of the protrusions 121, the card 10 and the housing 11 come into contact with each other. As a result, the heat dissipation efficiency of the electronic device 1 can be improved.

[0036] In order to be accommodated in the housing 11, the card 10 needs to be inserted while being agitated. For this reason, a gap may be provided 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, by attaching the fastener 12, the card 10 and the housing 11 come into contact with each other. 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 the present 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 provided 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 direction in which the card 10 is inserted. This makes it possible to ensure 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 is different 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 and then attach 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 is the same as the direction in which fastener 12 is attached, 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 operation when mounting card 10 in electronic device 1.

[0039] In the electronic device 1 of this embodiment, the distance between the two protrusions 121 facing each other is continuously shortened. For example, the two protrusions 121 provided on the fastener 12 may have a shape in which the protrusions 121 are inclined from the tip to the base on the side where the protrusions 121 face each other. When the distance between the protrusions 121 facing each other is continuously shortened, the gap between the card 10 and the housing 11 is continuously reduced in the process of attaching the fastener 12 to the card 10 and the housing 11. Therefore, the person attaching the fastener 12 can smoothly attach the fastener 12. For example, when the protrusions 121 provided on the fastener 12 are structured to become thicker in stages from the tip to the base, it may be difficult to attach the fastener 12 compared to when the distance between the protrusions 121 facing each other is continuously shortened. However, when the distance between the protrusions 121 facing each other is continuously shortened, for example, it may be easier to attach or remove the fastener 12.

[0040] In the electronic device 1 of this embodiment, the fastener 12 and the housing 11 are provided with screw holes 131 at corresponding positions, and the fastener 12 is attached to the housing 11 and the card 10 by the screws 13. When the fastener 12 is attached by the screws 13, for example, a person who removes the fastener 12 can also remove the fastener 12 by removing the screws 13. For example, the card 10 may be removed as needed. In this regard, 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 by the screws 13, it becomes possible to easily attach and detach the fastener 12.

[0041] In the electronic device 1 of the present embodiment, the two protrusions 121 are straight on the side opposite to the side where the protrusions 121 face each other. The two protrusions 121 are inserted into the hole 104 provided in the card 10 and the hole 111 provided in the housing 11. At this time, for example, when an incline is provided on the side opposite to the side where the protrusions 121 face each other and the side opposite to the side where the protrusions 121 face each other is a straight line, the size of the hole may be smaller than when an incline 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 the side opposite to the side where the protrusions 121 face each other be a straight line, 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-mentioned embodiments. Various modifications that can be understood by a person skilled in the art can be made to the configuration and details of the present disclosure within the scope of the present disclosure.
