Description

  This case relates to an electronic device.

  Some electronic devices have a first cover and a second cover that are assembled together to form an internal space therebetween, and various electronic devices are formed in the internal space formed by the first cover and the second cover. There is an electronic device having a structure in which components are mounted.

  For example, a notebook personal computer (hereinafter abbreviated as “notebook PC”) includes a main unit and a display unit, and each of the main unit and the display unit has the above-described structure. The main unit has a keyboard on the top surface, and various electronic components such as a circuit board on which a CPU is mounted are mounted in an internal space formed by the bottom cover and the top cover. The display unit includes an image display module having a display screen, and includes a front cover that surrounds the periphery of the display screen and a rear cover that covers the back surface of the image display module.

  In addition to the image display module, electronic parts such as a substrate on which a camera is mounted and an antenna are often mounted in the internal space formed by the front cover and the rear cover of the display unit.

  Here, there is one problem when a board such as a circuit board having a structure in which a connector is mounted and connected to the outside through the connector is accommodated in the internal space as described above. That is, such a plate is firmly fixed to the inner surface of the first cover or the second cover (here, referred to as the first cover) so as not to move carelessly. In this fixing, the connector fitted to the connector mounted on the plate is also fixed together with the plate so that the fitting is not removed while the connectors are fitted.

  However, it may be necessary to disassemble the electronic device for some reason during assembly of the electronic device. Alternatively, even after completion, the electronic device may need to be disassembled for repair or maintenance. However, at the time of disassembly, in the case of the above-described fixing structure, the connector cannot be removed unless the plate is removed, resulting in inconvenience in disassembling work. For example, the plate may be fixed to the first cover, and a cable may be connected to a connector that is combined with the connector on the plate, and the cable may extend to the second cover. In such a case, if the connector is not removed, the first cover and the second cover cannot be separated, and in order to remove the connector, it is necessary to remove the plate itself from the first cover, which hinders the disassembly work. .

  Here, various proposals have conventionally been made for fixing structures such as circuit boards. However, there is a proposal that satisfies both the fixing of the board such as the circuit board firmly including the prevention of the unmating of the connector and the removal of the connector without removing the board when disassembling. I can't find it.

JP 63-073698 A JP-A-11-68353 Japanese Patent Laid-Open No. 11-274765

Another connector 81 is combined with the connector 71 on the board. One end of a cable 82 is connected to the connector 81. The cable 82 extends toward the rear cover 512 (see FIG. 4) and is connected to an electronic component (not shown) mounted on the rear cover 512.

  FIG. 6 is a view showing a support portion on the inner surface of the front cover of the display unit in a state where the circuit board is supported. FIG. 7 is a view showing the support unit and the circuit board side by side with the circuit board removed from the support unit. Further, FIG. 8 is a view showing a second surface of the circuit board facing the inner surface of the front cover.

  The circuit board 70 has a shape extending left and right. As described above, the connector 71 is mounted on the first end portion in the left-right direction with the fitting surface facing outward. A mounting hole 72 is provided at a location slightly inside the first end and a location slightly inside the second end opposite to the first end. ing. Further, the circuit board 70 has a notch 74 having a shape in which a side surface 73 extending in the left-right direction is notched in a central portion away from both the first end portion and the second end portion.

  On the second surface (the surface shown in FIG. 8) facing the inner surface side of the front cover 511 of the circuit board 70, microphones 79, which are a kind of electronic component, are mounted on both left and right ends. Signals obtained by picking up sound with the microphones 79 are transmitted to the outside of the circuit board 70 via the connector 71, the connector 81, and the cable 82.

  On the other hand, the support portion 90 provided on the inner surface of the front cover has the circuit board 70 facing the inner surface of the front cover 511 with the second surface (see FIG. 8) facing the inner surface of the front cover 511. It is a support part supported in a state. A boss 91 that enters the hole 72 of the circuit board 70 is erected at positions slightly inward from the left and right ends of the support portion 90, and a circuit portion is provided at the center portion away from the left and right ends. Ribs 92 that fit into the notches 74 of the substrate 70 are formed. The circuit board 70 is “slowly” supported by the support portions 90 on the inner surface of the front cover 511 by these bosses 91 and ribs 92. The meaning of “slowly” will be described later.

  In addition, the support portion 90 is provided with an earpiece 55 (see also FIG. 2) at a position corresponding to two microphones 79 (see FIG. 8) mounted on the circuit board 70.

  The horizontal direction of the circuit board 70 is regulated by the first rib 93 and the second rib 94. The first rib 93 is a rib standing on the inner surface of the front cover 511 along the back surface of the connector 81 in a state of being fitted to the connector 71 on the circuit board 70 with respect to the fitting surface with the connector 71. The second rib 94 is erected on the inner surface of the front cover 511 on the second end side of the circuit board 70 opposite to the first end on the side where the connector 71 is mounted. A rib that regulates the position of the circuit board in the left-right direction. The second rib 94 is erected along the end surface 70 a (see FIGS. 6 to 8) on the second end side of the circuit board 70.

  Further, the position of the circuit board 70 in the width direction (vertical direction of the display unit 50 in the open state shown in FIGS. 2 and 3) is regulated by both walls 95 rising along both side surfaces of the circuit board 70.

  Next, the positional restriction of the circuit board 70 in the direction of lifting from the inner surface of the front cover 511 will be described.

  9 to 11 are perspective views showing the first end portion side of the circuit board supported by the support portion on which the connector is mounted, from different angles, respectively. FIGS. 12 and 13 are perspective views showing portions of the support portion of the inner surface of the front cover that support the first end of the circuit board from different angles.

  The support portion 90 has a rib 96 erected along the side surface near the first end portion of the circuit board 70, and further from the rib 96 to the first surface of the circuit board (the surface on the side where the connector 71 is mounted). ) Has an overhanging piece 961 overhanging. The projecting piece 961 projects from the first surface of the circuit board 70 so as to be spaced apart from the first surface. Since the circuit board 70 is “slowly” supported by the bosses 91 and ribs 92 described above, the circuit board 70 projects the first end portion of the circuit board 70 on which the connector 71 is mounted. It can be lifted until it abuts the piece 961. The first rib 93 erected along the back surface of the connector 81 has a height that allows the back surface of the connector 81 to be detached when the first end side of the circuit board 70 is lifted. For this reason, with the circuit board 70 supported by the support portion 90, the first end side is lifted and the connector 81 is removed from the connector 71 on the circuit board 70, or the connector 81 is fitted to the connector 71. Can do.

  FIG. 14 is a perspective view showing the vicinity of the second end portion of the circuit board supported by the support portion on the side opposite to the first end portion on which the connector is mounted.

  Here, a rib 97 extending in a direction along the side surface of the circuit board is erected, and a projecting piece 971 projects from the rib 97 onto the first surface of the circuit board 70. The projecting piece 971 projects to a height closer to the first surface than the projecting piece 961 (see FIG. 10 and the like) on the first end side of the circuit board 70, and the second end of the circuit board 70. The floating of the part close to the part from the front cover 511 is restricted.

  When the first end side of the circuit board 70 is lifted as described above, the circuit board 70 rotates around the end surface 70a on the second end side. The overhanging piece 961 on the second end side is close to the end surface 70a. Therefore, the overhanging piece 961 only slightly floats from the circuit board 70, so that the rotation of the circuit board 70, i.e., the first end part. Does not interfere with side lifting. The overhanging piece 971 on the second end side protrudes to a height position slightly away from the circuit board 70 to allow the first end side of the circuit board 70 to be lifted. The overhanging piece 971 on the second end side may be a height that contacts the first surface of the circuit board 70, and the first end side may be lifted by slightly bending the circuit board 70.

  FIG. 15 and FIG. 16 are perspective views showing the circuit board supported by the support portion, with the connector 81 connected to the cable 82 removed, from different angles.

  When the connector 81 to which the cable 82 is connected is removed from the connector 71 on the circuit board 70, the front cover 511 and the rear cover 512 can be separated. Even in such a case, the circuit board 70 remains supported by the support portion 90 on the inner surface of the front cover 511 by the boss 91 or the like.

  As described above, the rib 64A (see FIG. 4) as an example of the second rib in the present case is erected on the inner surface of the rear cover 512. The rib 64 </ b> A presses the connector 71 on the circuit board 70 when the rear cover 512 and the front cover 511 are assembled, and presses the circuit board 70 against the inner surface of the front cover 511. As a result, the rib 93 erected along the back surface of the connector 81 is at a height position overlapping the back surface of the connector 81, and restricts the displacement in the left-right direction of the circuit board 70 including the connector 81.

  As described above, according to the present embodiment, the circuit board 70 is “securely” supported by the support portion 90 by assembling the rear cover 512 and the front cover 511. On the other hand, in a state where the front cover 511 is removed from the rear cover 512, the first end portion side of the circuit board 70 on which the connector 71 is mounted can be lifted. By lifting the first end side, the connector 81 can be removed from the connector 71 and the connector 81 can be reinserted into the connector 71 without removing the circuit board 70 from the support portion.

  FIG. 17 is a view showing the camera substrate mounted on the rear cover of the display unit above the display screen.

  The camera substrate 60 is equipped with a camera 61 and circuits for controlling the camera 61 and for signal processing. The signal exchange between the camera substrate 60 and the outside is performed by a connector 62 mounted on the camera substrate 60 and a connector 64 connected to the connector 62 and connected with a cable 65. However, the camera substrate 60 is irrelevant to the separation of the rear cover 512 and the front cover 511. For this reason, in this embodiment, the structure which makes the fixation of a circuit board and the ease of insertion / extraction of a connector like the circuit board 70 which mounted the microphone 79 mentioned above not employ | adopted. The camera 61 on the camera substrate 60 and the microphone 79 on the circuit substrate 70 described above generate signals (image signals and audio signals) for moving image communication with audio, for example, video communication such as a videophone. .
