DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board holding device used for VTRs, TVs, audio equipment, personal computers and the like.

[0002]

2. Description of the Related Art Conventionally, as this type of printed circuit board holding device, one shown in FIGS. 5 to 7 is known. In FIG. 5, reference numeral 1 denotes a base such as an apparatus main body or a side plate of a chassis, and a main printed circuit board 2 is fixed to the base 1 by means not shown. When the sub-printed circuit board 4 is held on the base 1, the connector 3 fixed to the printed circuit board 2 and the connector 5 fixed to the printed circuit board 4 are connected by fitting. The printed circuit board 4 is screwed to the base 1 with screws 7. Such a printed circuit board holding device has a problem that the cost is increased and the number of assembling steps is increased due to the use of screws.

In FIG. 6, the base 1 is provided with a guide 6 for guiding the sub-printed circuit board 4 in a direction along the plate surface, and by moving the printed circuit board 4 along the guide 6, The connector 3 and the connector 5 are connected. In FIG. 6, the same components as those in FIG. 5 indicate the same components. In such a printed board holding device, the sub-printed board 4 cannot be moved in a direction penetrating the board surface to connect the connectors 3 and 5 to each other. Therefore, other components cannot be arranged at the position where the printed board 4 moves on the base 1, and both the main printed board 2 and the other printed boards arranged in parallel with the board 2 are not provided. In addition, the sub-printed circuit board 4 cannot be connected via a connector.

In FIG. 7 as well, a guide 6 for guiding the sub-printed circuit board 4 in a direction along the plate surface is provided on the base 1, and by moving the printed circuit board 4 along the guide 6, The connector 3 and the connector 5 are connected. Therefore, as in the case of FIG. 6, the sub-printed circuit board 4 cannot be moved in a direction penetrating the board surface to connect the connectors 3 and 5 to each other.

[0005]

As described above, in the conventional printed circuit board holding device, when the printed circuit board is moved in a direction penetrating the board surface to connect the connectors, screws must be used. However, the use of these screws increases costs and increases the number of assembly steps. Also, in the case of connecting the connectors by moving the printed circuit board in a direction along the plate surface,
No other components can be placed at the position where the printed circuit board moves on the base, and this printed circuit board is placed in a direction perpendicular to the direction of movement of the printed circuit board. There has been a problem that it cannot be connected to the substrate via a connector. The present invention has been made in view of the above, and it has been made possible to connect a connector by moving a printed circuit board in a direction penetrating the board surface without using screws, and to be able to maintain this state. It is an object of the present invention to provide a printed circuit board holding device.

[0006]

According to the present invention, there is provided a printed circuit board holding device for solving the above-mentioned problems and connecting the connector fixed to a printed circuit board to a connector fixed to a base. A printed circuit board holding device for holding the printed circuit board on the base in a state in which the connectors are connected as described above by moving the printed circuit board in a direction penetrating the board surface. The base has a guide having a top portion that is disposed so as to sandwich the printed board in a state where the connectors are connected as described above, and the printed board is sandwiched between the guides. Further, the connector is held by the base by connecting the connectors to each other.

[0007]

In the printed circuit board holding device constructed as described above, the printed circuit board can be moved in the direction along the surface of the printed circuit board, and can be rotated around the top of the guide as a fulcrum. By this rotation, the connectors are connected to each other.

[0008]

1 and 2 show an embodiment of the present invention.
Will be described. 1 and 2, reference numeral 8 denotes a guide for the sub-printed circuit board 4, which is fixed to the base 1.
In a state where the connectors 3 and 5 are connected to each other, the connector has a top portion opposed to the printed circuit board 4 so as to sandwich the printed circuit board 4.
It is composed of two triangular prisms. The interval between these tops is slightly larger than the thickness of the printed circuit board 4. 1 and 2, the same reference numerals as those in FIGS. 5 to 7 denote the same components. 1 and 2, two main printed circuit boards 2, 2 having respective connectors 3, 3 are provided in parallel.

In the printed circuit board holding apparatus constructed as described above, the connector 3 is moved by moving the sub-printed circuit board 4 in the direction indicated by arrow A in FIG. , 3, and 5, 5 are connected to each other, and the printed circuit board 4 is held on the base 1 in this state. In FIGS. 1 and 2 described above, the case where two main printed boards 2 and 2 are provided in parallel has been described.
As shown in FIG. 3, when another component 9 is provided on the base 1 at a position where the sub-printed board 4 rotates, the printed board 4 Can be rotated.

When another component 9 is provided at the position shown in FIG. 4, the printed circuit board 4 is rotated,
The printed circuit board 4 can be inserted to the above-mentioned predetermined position avoiding the component 9 by moving straight along the board surface. By rotating the printed board 4 at this predetermined position, the connectors 3 and 5 are connected to each other, and the printed board 4 is held on the base 1 in this state. In each of the above embodiments, the connector 3 is fixed to the base 1 via the main printed circuit board 2.
It may be fixed to.

[0011]

Since the present invention is configured as described above, the printed circuit board is moved in a direction penetrating the board surface without using screws, and the connectors are connected to each other. Since the printed circuit board can be held quickly, the cost is not increased and the number of assembling steps is not increased due to the use of screws as in the related art. And, since the printed circuit board is moved in a direction penetrating the board surface to connect the connectors, other components can be arranged at the position where the printed circuit board moves on the base,
In addition, the printed circuit board can be connected to a plurality of printed circuit boards arranged in parallel with each other in a direction perpendicular to the board surface via a connector.
