  As shown in FIGS. 2 to 4, the plurality of support members 13 are arranged at positions corresponding to the through holes 41 of the sub-substrate 12 (that is, positions facing each other). As shown in FIG. 4, each column member 13 has a screw hole 42 that communicates with the through hole 41 of the sub-board 12. As used herein, “screw hole” refers to a hole in which a female screw is formed.

  As shown in FIG. 2, the plurality of fastening members 18 are attached to the pressing member 17. Each fastening member 18 is, for example, a screw. As shown in FIG. 4, each fastening member 18 is attached from the pressing member 17 toward the main board 11.

  As shown in FIG. 3, the plurality of fastening members 18 are respectively inserted into the through holes 38 of the fixing portion 32 of the pressing member 17 and the through holes 41 of the sub-board 12 and engage with the screw holes 42 of the column member 13. As a result, the fastening member 18 fixes the pressing member 17 to the sub-board 12 and also fixes the sub-board 12 to the support member 13. That is, the fastening member 18 fixes the sub board 12 to the main board 11 via the support member 13. That is, the pressing member 17, the sub board 12, and the main board 11 are integrally fixed by the fastening member 18.

  As shown in FIG. 2, two fastening members 18 among the plurality of fastening members 18 fix the holding members 17 to the sub-boards 12 at positions on the connection connector 14 side with respect to the main body portion 31 of the holding member 17. In addition, the sub-board 12 is fixed to the support member 13.

The main board 11 has a cutout portion 44 cut out so as to avoid the fin unit 22 and the cooling fan 23. The fin unit 22 and the cooling fan 23 are disposed in the notch 44 and are disposed at positions away from the main board 11 (that is, positions not overlapping the main board 11).

  As shown in FIG. 3, the fin unit 22 is disposed on the main substrate 11 side with respect to the heat pipe 21 with respect to the thickness direction of the main substrate 11 (the vertical direction in FIG. 3). That is, the fin unit 22 is located closer to the main substrate 11 than the heat pipe 21 in the thickness direction of the main substrate 11.

  More specifically, the heat pipe 21 has a first region 46 (for example, a lower surface region) that faces the main substrate 11 and a second region 47 (for example, an upper surface region) that faces away from the main substrate 11. ing. The first region 46 has a portion 48 extending away from the main substrate 11. The fin unit 22 is attached to a portion 48 extending away from the main board 11 in the first region 46 of the heat pipe 21. As shown in FIG. 3, the fin unit 22 and the cooling fan 23 are arranged on the main board 11 along a direction parallel to the first surface 12 a of the sub board 12.

  According to the portable computer 1 having such a configuration, the connection reliability of the connection connector 14 can be improved. That is, in the portable computer 1, the two fixing portions 32 of the pressing member 17 are positioned on the connection connector 14 side with respect to the main body portion 31, and the two fastening members 18 are connected to the main body portion 31 of the pressing member 17. At a position on the connector 14 side, the pressing member 17 is fixed to the sub board 12 and the sub board 12 is fixed to the main board 11.

  Thereby, a fixing structure for connecting the sub board 12 and the main board 11 near the connection connector 14 is realized. With this fixing structure, the periphery of the connection connector 14 is relatively firmly held, and the connection connector 14 is not easily deformed even when a load is applied to the sub-board 12. That is, the stress applied to the connection connector 14 is reduced. Thereby, the connection connector 14 becomes difficult to produce a malfunction, and connection reliability improves.

  Further, according to the portable computer 1 according to the present embodiment, it is possible to improve the mounting density. For example, the sub-board 12 has a through-hole 41 that communicates with the through-hole 38 of the holding member 17, and the column member 13 is disposed at a position corresponding to the through-hole 41 of the sub-board 12. When the fastening member 18 is inserted into the through hole 38 of the pressing member 17 and the through hole 41 of the sub-board 12 and engages with the screw hole 42 of the column member 13, the pressing hole 42 communicates with the through hole 41. The sub board 12 can be fixed to the main board 11 by the fastening member 18 for fixing the member 17.

  When the sub board 12 is fixed to the main board 11 by the fastening member 18 for fixing the holding member 17, the fixing structure originally provided for fixing the sub board 12 to the main board 11 can be omitted. That is, it is not necessary to provide a dedicated through hole for the sub-board 12 in order to fix the sub-board 12 to the main board 11, and the board area of the sub-board 12 increases accordingly. Thereby, the wiring pattern can be formed also in the region where the through hole was originally provided. In other words, the sub-board 12 can be reduced in size by the area where the through hole is provided. These contribute to the improvement of the mounting density of the portable computer 1. That is, the portable computer 1 can improve the connection reliability of the connection connector 14 while improving the mounting density.

  When the two fixing portions 21 positioned on the connection connector 14 side with respect to the main body portion 31 are aligned with each other along the longitudinal direction of the connection connector 14, the periphery of the connection connector 14 is more stably held.

  One fixing portion 23 of the two fixing portions 32 located on the connection connector 14 side with respect to the main body portion 31 is opposed to one end portion 25a in the longitudinal direction of the connection connector 14, and the two fixing portions 32 Of these, the other fixing portion 32 faces the other end portion 25 b of the connection connector 14 in the longitudinal direction. According to this, the periphery of the connection connector 14 is stably held over the entire length of the connection connector 14 in the longitudinal direction.

  The pressing member 17 having a Y shape is disposed with the V-shaped portion 34 facing the connection connector 17. According to this, the two fixing portions 32 can be arranged near the connection connector 14 by the pressing member 17 having only the three fixing portions 32, and the connection reliability of the connection connector 14 can be improved.

The connector fixing portion 82 is an example of a support member referred to in the present invention, and is interposed between the main board 11 and the sub board 12.

  The through hole 38 of the fixing portion 32 of the pressing member 17 and the through hole 41 of the sub-board 12 are arranged in a region facing the connector fixing portion 82. Each connector fixing portion 82 has a through hole 83 that communicates with the through hole 41 of the sub-board 12. The main board 11 has a screw hole 84 that communicates with the through hole 83 of the connector fixing portion 82.

  As shown in FIG. 14, each fastening member 18 is inserted into the through hole 38 of the fixing portion 32 of the pressing member 17, the through hole 41 of the sub-board 12, and the through hole 83 of the connector fixing portion 82. The screw hole 84 is engaged. As a result, the fastening member 18 integrally fixes the pressing member 17, the sub board 12, the connection connector 14, and the main board 11.

  According to the portable computer 1 having such a configuration, it is possible to improve the connection reliability of the connection connector 14 while improving the mounting density, as in the first embodiment.

  In the present embodiment, the fastening member 18 for fixing the pressing member 17 serves as a fastening member for fixing the sub-board 12 to the main board 11 and a fastening member for fixing the connection connector 14 to the main board 11. It also serves as a role. According to such a configuration, a fixing structure that is originally provided to fix the connection connector 14 to the main board 11 can be omitted. This contributes to an improvement in mounting density and a reduction in the number of parts.

  Although the portable computer 1 according to the first to eighth embodiments of the present invention has been described above, the present invention is not limited to these. The components according to each embodiment can be implemented in appropriate combination. For example, in the second to sixth embodiments, the stacking connector according to the seventh or eighth embodiment may be used as the connection connector. Further, the present invention can be embodied by modifying the constituent elements without departing from the spirit of the invention in the implementation stage.
