Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board mounting structure for facilitating connection between connectors of both circuit boards when mounting circuit boards on a device frame.

[0002]

2. Description of the Related Art In various electronic devices such as personal computers, in order to effectively use a limited space, circuit boards are often mounted on a device frame so that the circuit boards are connected by connectors.

When the circuit board is mounted on the device frame in the case where the size of the circuit board is large or small, the first small circuit board (for example, a relay board) is mounted on the device frame first.
A second circuit board larger than the first circuit board may be attached to the device frame so as to cover the first circuit board.

Specifically, there are, for example, a first circuit board 10 as shown in FIG. 7A and a second circuit board 20 as shown in FIG. 7B. It is assumed that the connectors 10 and 20 are provided on the connectors 10 and 20, respectively. The first circuit board 1 is first attached to the device frame.
0 is mounted, and the second circuit board 20 is mounted so as to cover the circuit board 10. At that time, by connecting the connector 21 of the second circuit board 20 to the connector 11 of the first circuit board 10, the two circuit boards 10 and 20 are connected to each other.
It is electrically connected at 21.

[0005]

However, since the second circuit board 20 is larger than the first circuit board 10,
As shown in FIG. 8, when the second circuit board 20 is mounted, the connector 11 of the first circuit board 10 cannot be seen, and it is difficult to align the connectors 11 and 21 with each other.
There is a problem that it takes time to connect 1 and 21 and work efficiency is reduced.

The present invention has been made in view of such a problem, and a circuit for facilitating the connection between the connectors of both circuit boards when the circuit boards are stacked and attached to the apparatus frame. It is intended to provide a mounting structure for a substrate.

[0007]

In order to achieve the above object, a circuit board mounting structure of the present invention has a first circuit board and a second circuit board, and is mounted on a frame of the mounting structure. In a circuit board mounting structure for mounting a second circuit board by connecting a connector of the second circuit board to a connector of the first circuit board, a support portion for supporting one side of the second circuit board. Are provided on the frame, markers are provided on the one side of the second circuit board and at corresponding positions on the frame, respectively, and one side of the second circuit board is supported by a supporting portion of the frame to form a second circuit. It is characterized in that the connectors of both circuit boards are connected by pushing the second circuit board to the first circuit board in a state where the markers of both the board and the frame are aligned.

In this mounting structure, while supporting one side of the second circuit board by the supporting portion of the frame, the marker on the one side of the second circuit board is aligned with the marker of the frame, and the second circuit board is attached. By pressing on the first circuit board, the connectors of both circuit boards can be connected, so that the efficiency of the assembling work can be improved. That is, since the connectors can be automatically aligned by aligning the markers with each other, the operation of pressing the markers together can be performed mechanically, and the assembling work can be efficiently performed.

The marker on one side of the second circuit board may be formed by silk printing, for example.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to embodiments.

However, for convenience of explanation, it is assumed that the first circuit board is as shown in FIG. 7A, and the description thereof is omitted.
The circuit board of is shown in FIG. 7 (b).

As shown in FIG. 1, in the second circuit board 20, one side on the side opposite to the side on which the connector 21 is attached is mounted.
A marker 25 is applied to the side (lower part) by silk printing. Here, the number of markers 25 is three,
The shape is semicircular, but the number may be appropriately increased or decreased, and at least one may be used if it is easy to align with the marker on the frame side described later. In addition, if the shape can be aligned with the marker on the frame side, the shape such as a quadrangle, a triangle, or an arrow is not specified.

The markers provided on the device frame are as shown in FIGS. 2 to 4, for example. Here, FIG.
The markers shown in FIG. 4 are for the case where the second circuit board 20 is mounted upright on the frame.

In FIG. 2, the frame is provided with a pair of semicircular support portions 41 on a straight line (one-dot chain line). The pair of support portions 41 support one side of the second circuit board 20 and also serve as markers. The distance between the pair of support portions 41 is set to be slightly larger than the thickness of the second circuit board 20. Has been done. Further, the pair of support portions 41 are provided in three pairs corresponding to the number of the markers 25 on the second circuit board 20 and have substantially the same shape and the same size as the markers 25. Good. The support portion 41
Is formed, for example, by cutting and raising a predetermined portion 42 of the frame in a semicircular shape.

In FIG. 3, a pair of rail-shaped support portions 43 as shown in the figure are attached to the frame, and three pairs of semicircular markers 44 are formed on the support portion 43. The pair of support portions 43 supports one side of the second circuit board 20, and the marker 44 has a convex shape and corresponds to the marker 25 of the second circuit board 20.

In FIG. 4, a pair of rail-shaped support portions 45 are attached to the frame, and three pairs of semicircular markers 46 are formed on the support portion 45. The pair of support portions 45 also support one side of the second circuit board 20, and the marker 46 has a cutout shape, and similarly corresponds to the marker 25 of the second circuit board 20.

In the support portion 41 of FIG. 2, the connector 21 of the circuit board 20 and the connector 11 of the first circuit board 10 are aligned when the marker 25 of the second circuit board 20 is aligned with the support portion 41. As described above, it is pre-positioned on the device frame. In addition, the supporting portion 4 of FIGS.
3, 45 also have markers 25 and 44, 4 respectively.
It is positioned in the device frame so that the connectors 11 and 21 match when the connector 6 is aligned.

Next, the mounting structure of the second circuit board 20 of FIG. 1 and the first circuit board 10 of FIG. 7A will be described. However, the marker on the device frame side is the support portion 41 also used as the marker shown in FIG. First circuit board 10
Is attached to the device frame 30 in a vertical direction prior to the mounting of the second circuit board 20, as shown in FIG.
In that state, in FIG. 5, while fitting one side of the second circuit board 20 between the support portions 41 of the frame 30, the three markers 25 are aligned with the support portions 41 also serving as the three markers.

Then, as shown in FIG. 6A, the second
Using one side of the circuit board 20 as a fulcrum, the circuit board 20 is erected in the arrow direction so as to be vertical. Then, the connector 21 of the second circuit board 20 is connected to the connector 11 of the first circuit board 10, and the second circuit board 20 is mounted on the first circuit board 11. Of course, the mounting work can be performed in the same manner with the marker-equipped support portions 43 and 45 shown in FIGS. 3 and 4.

In the above embodiment, the second circuit board 20 is described as being larger than the first circuit board 10, but the same is applicable when both circuit boards 10 and 20 have substantially the same size. Is. In short, the first circuit board 1
There is no limitation on the size of the board as long as the connectors 11 and 21 of both circuit boards 10 and 20 can be easily connected when the second circuit board 20 is attached to 0 later.

In the above-described embodiment, the first and second circuit boards 10 and 20 are vertically set on the device frame, but both circuit boards are arranged horizontally, that is, on the first circuit board. The same can be applied to the case where the second circuit board is overlapped with.
