Description

  The present invention relates to a support structure that supports a printed circuit board (hereinafter referred to as a substrate) in a direction perpendicular to a frame, a card slot holder in which a card slot is mounted on the frame, and a thin device that houses the card slot holder. .

  Conventionally, an electronic device having an electronic circuit is usually configured by mounting electronic components on a substrate. The space in which the substrate is stored is limited because there is a demand for miniaturization and space saving with respect to the electronic device. Therefore, the electronic components mounted on the substrate are also arranged as densely as possible. As a result, with respect to a specific electronic component, there is a case where the substrate is mounted perpendicularly to the frame and the electronic component is mounted on the substrate due to restrictions on the mounting direction of the electronic component. Conventionally, the sub-board is attached to the main board on the frame as shown in FIGS.

In FIG. 9, the left and right sides of the sub-board 21 are supported by guides 22 and 23 having a U-shaped cross section, and a boss 24 is erected in the immediate vicinity of the sub-board 21, and a washer 25 is inserted into the boss 24. And the upper end of the sub-board 21 is pressed by the washer 25. In FIG. 10, a claw 26 is erected in place of the boss 24 of FIG. 9, and the claw 26 is engaged with the upper end of the sub-board 21. In FIG. 11, a claw 27 shorter than the claw 26 of FIG. 10 is erected, and a hole 28 is opened in the lower part of the sub-board 21, and the claw 27 is engaged with the hole 28.

In FIG. 12, one side of one guide 29 is extended toward the center of the sub-board 21, and a hole is also formed in the sub-board 21 corresponding to the position, and a screw 30 is inserted from the other side of the hole. The sub-board 21 is fixed by inserting and screwing into the extended portion. In some cases, a detection unit that detects the movement of the movable part of the mechanism such as the card slot or the movement of the card itself is mounted on the sub-board. Positioning with the detection unit on the board becomes important, and a highly accurate mounting work between the mechanism and the sub board is required. Also, if the position between the mechanism and the sub board is misaligned, or if an abnormality occurs in the detection part on the sub board, it is necessary to readjust the mounting position of the sub board or replace the detection member on the sub board. The workability at that time has never been easier. In addition, as a conventional technique for attaching the sub board perpendicular to the main board, in addition to the above, “electronic device” described in Patent Document 1, and “insulating fiber fixing structure of electronic device” described in Patent Document 2, There are a “series unit” described in Patent Document 3 and a “printed circuit board support structure” described in Patent Document 4.

  However, in the case of the method shown in FIG. 9, although the sub-board is securely held, there are disadvantages that an excessive force is applied to the sub-board and the mounting area of the components is reduced. In the case of the method shown in FIG. 10, since the height of the nail is high, it is difficult to mold the nail, and the backlash occurs when the size of the substrate is minus the height to the nail engagement position. In addition, there is a drawback that the mounting area of the parts is reduced. In the case of the method shown in FIG. 11, the mounting area of the component is larger than that in the case of FIG. 10, but the backlash becomes larger and the movable range of the tip of the claw becomes smaller because the claw is shorter. There was a drawback that the size was reduced.

In the case of the method shown in FIG. 12, although the sub-board is securely held and the mounting area is increased, the direction of the driver that loosens the screw when the sub-board needs to be removed after the sub-board is once attached is the lateral direction. Therefore, there is a drawback that the work may not be possible. In some cases, a detection unit that detects the movement of the movable part of the mechanism such as the card slot or the movement of the card itself is mounted on the sub-board. Positioning with the detection unit on the board becomes important, and a highly accurate mounting work between the mechanism and the sub board is required. Also, if the position between the mechanism and the sub board is misaligned, or if an abnormality occurs in the detection part on the sub board, it is necessary to readjust the mounting position of the sub board or replace the detection member on the sub board. The workability at that time has never been easier.

Therefore, the present invention provides a printed circuit board support structure that can be attached and detached from above when the sub board is mounted vertically with respect to the main board, the mounting area of the components is not significantly reduced, and no play is generated. In addition to proposing, when the detection unit that detects the movement of the movable part of the mechanism such as the card slot and the movement of the card itself is mounted on the sub-board, the positional accuracy between the detection unit and the detected part is easily This invention aims to propose a structure to be maintained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 4 are perspective views showing a PC card slot frame (hereinafter referred to as a frame) installed above a main board in a liquid crystal television having a PC card slot. 1 and 2 show a state in which the sub board is not mounted, and FIGS. 3 and 4 show a state in which the sub board is mounted. 5 is a plan view of a portion of the frame on which the sub-board is mounted, and FIG. 6 is a cross-sectional view taken along the line AA in FIG. In these drawings, reference numeral 1 denotes a frame made of a resin molded product, which is disposed above a main board (not shown) in parallel with the main board.

Frames 3 and 4 that support the left and right ends of the sub-board 2 are erected at the end of the frame 1 on which the sub-board 2 is mounted. At the end of the right frame 3 formed in an L-shaped cross section, a vertically long cantilever 5 is projected in parallel to the frame 1 and the sub-board 2 to be mounted up to the center in the horizontal direction of the sub-board 2. ing. A claw 6 for engaging with the engagement hole 2 a of the sub-board 2 protrudes from the back surface of the front end of the cantilever 5 (surface on the sub-board 2 side). On the surface side closer to the base end of the cantilever 5 than the claw 6, an inclined surface 7 is formed in which the upper end is inclined toward the sub-substrate 2 side and the lower end is inclined away from the sub-substrate 2.

A screw hole 9 for screwing the screw 8 is formed in the frame 1 below the inclined surface 7 in the vertical direction. When the sub-board 2 is mounted on the frame 1 configured in this way, the sub-board 2 is inserted into the frames 3 and 4 with the engagement hole 2a of the sub-board 2 being the front surface. Here, after confirming that the engagement hole 2 a is positioned in front of the claw 6, the screw 8 is screwed into the screw hole 9. As the screw 8 is screwed, the side surface of the head of the screw 8 is lowered and comes into contact with the inclined surface 7. Further, when the screw 8 is screwed, the inclined surface 7 is pressed and moved to the sub-board 2 side, and the claw 6 enters the engagement hole 2a and is engaged. Next, when the back end of the cantilever 5 on which the claws 6 are formed comes into contact with the surface of the sub-board 2, the screwing of the screw 8 is finished.

Thus, in the present invention, the sub-board 2 is engaged with the claw 6 at the tip of the cantilever 5 and cannot be removed from the frame 1, and the back surface of the tip of the cantilever 5 presses the surface of the sub-board 2. The sub board 2 is more firmly fixed to the frame 1. In FIG. 6, the engagement hole 2 a formed in the sub-board 2 passes through. However, if the groove is formed only on one side without passing through, the component mounting area on the back side is not impaired. . Further, by making the cross-sectional shape of the cantilever 5 vertically long and making the horizontal section coefficient smaller than the vertical section coefficient, when the inclined surface 7 is pressed by the screw 8, the cantilever 5 is moved in the horizontal direction. It is easy to bend. In the illustrated example, a pan screw is used as the screw 8, but this is a countersunk screw, and the inclination angle of the side surface of the head of the countersunk screw is the same as the inclination angle of the inclined surface 7. It is also possible to distribute the applied load.

The above-described frame 1 is arranged on the upper surface of a main board on which a PC card slot is mounted in a liquid crystal television. FIGS. 7 and 8 show that the frame 1 is arranged on the main board. FIG. 2 is a perspective view showing a state where PC card slots are mounted in two stages. In the figure, reference numeral 11 denotes a main board on which a frame 1 is mounted. On the upper surface of the frame 1, PC card slots 12 and 13 are mounted in two layers. On the side surfaces of the PC card slots 12 and 13, there are provided moving bars 18 and 19 that move along the side surfaces of the PC card slots 12 and 13 when the buttons 16 and 17 are pushed. Steps 12 and 13 have different step portions with different intervals. Micro switches 14 and 15 are attached to the front side surface of the sub-board 2 at positions facing the moving bars 18 and 19 in two upper and lower stages, and the PC card slot 12 is bordered by the stepped portions of the moving bars 18 and 19. , 13 detects that a PC card has been loaded.

FIG. 7 shows a state where it is detected that the PC card eject buttons 16 and 17 are pushed in, and FIG. 8 shows a state where it is detected that the PC card eject buttons 16 and 17 are projected. The sub-board 2 to which the microswitches 14 and 15 are attached is fixed to the frame 1 by the cantilever 5 and the screw 8 as described above. The sub-board 2 can be attached to and detached from the frame 1 because the screw 8 is screwed perpendicularly to the frame 1 and can be operated by a driver from above the frame 1. That is, even after the PC card slots 12 and 13 are mounted on the frame 1, the sub-board 2 can be removed and the microswitches 14 and 15 can be replaced. As described above, when the movement of the moving bars 18 and 19 is detected by the microswitches 14 and 15 on the sub-board 2, the positional relationship between the moving bars 18 and 19 and the microswitches 14 and 15 on the sub-board 2 is determined. Is important, and if the positional relationship between them is shifted, the movement of the moving bars 18 and 19 may not be detected or may cause a false detection. As described above, the PC 1 slot mounting portion and the sub-board 2 on which the microswitches 14 and 15 are mounted are integrally formed on the frame 1, so that the mutual positional relationship can be accurately obtained.

FIG. 13 is a perspective view showing an embodiment in which the frame 1 having the PC card slot described above is incorporated in a liquid crystal television as a thin device, and FIG. 14 is a top view of the right end of FIG. 13 as viewed from above. is there. Speaker boxes 23 and 24 are arranged on the left and right sides of the liquid crystal television main body 22 supported by the stand 21. A PC card slot (not shown) is incorporated in the back cabinet 25 on the back side of the back of the right end of the speaker box 24, and the PC card 27 is inserted and removed from the slot port 26 by the user. Projected at the lower end of the slot port 26 is a button 28 for taking out the PC card 27.

The PC card slot incorporated in the liquid crystal television main body 22 is incorporated with the liquid crystal television main body 22 and the PC card slot having the same thickness direction in parallel with the screen because the liquid crystal television main body 22 has a thin shape. The thickness is reduced. At this time, the mounting direction of the screw 8 in FIGS. 7 and 8 is from the rear in the thickness direction of the liquid crystal television main body 22, and the sub-board 2 can be attached and detached easily. That is, even after the frame 1 having the PC card slot mounted therein is incorporated into the liquid crystal television main body 22, if the rear cabinet 25 is removed, the screws 8 can be attached and detached, and the sub-board 2 can be attached and detached. Improved workability.

  The present invention is not limited to an electronic device in which a detection unit for detecting the movement of a movable part of a mechanism such as a PC card slot or the movement of a contained medium itself is mounted on a sub board. The present invention can be used for AV equipment having an electronic circuit portion for mounting a substrate vertically, other electronic equipment, particularly thin electronic equipment.
