Abstract

PURPOSE: To cut down the assembly manhours and connect plurality of printed boards through the intermediary of connectors by a method wherein the printed boards are held by a guide having oppositely arranged crests to be rotated in the piercing direction of the board face of printed board for connecting connectors to one another to hold the printed board in such a state. CONSTITUTION: Guides 8 of a subprinted board 4 is fixed to a base 1 to be composed of two each of triangle poles having opposite crests as if holding the printed board 4 in the state of connectors 3, 5. The gap between these crests is set up to be slightly larger than the thickness of the printed board 4. Next, this subprinted 4 is shifted in the direction of arrow A and a specific position to be rotated as shown by an arrow B so that connectors 3, 3, and 5, 5 may be mutually connected while the printed board remains on the base 1, thereby enabling the assembly manhours to be cut down using no screws at all.

[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 equipments, 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 has been known. In FIG. 5, reference numeral 1 is a base such as a side plate of a device body or a chassis, and a main printed circuit board 2 is fixed to the base 1 by means not shown. When holding the sub-printed circuit board 4 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 fitted and connected, and further, The printed circuit board 4 is screwed to the base 1 with screws 7. In such a printed circuit board holding device, there are problems that the cost is increased by using screws and the number of assembling steps is increased.

In FIG. 6, the base 1 is provided with a guide 6 for guiding the sub-printed circuit board 4 in the 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 reference numerals as those in FIG. 5 denote the same elements. In such a printed circuit board holding device, it is not possible to move the sub-printed circuit board 4 in a direction passing through the plate surface to connect the connectors 3 and 5 to each other. Therefore, other components cannot be arranged at the position on the base 1 where the printed circuit board 4 moves, and both the main printed circuit board 2 and the other printed circuit boards arranged in parallel with this circuit board 2. In addition, the sub-printed circuit board 4 cannot be connected via the connector.

In FIG. 7 as well, the base 1 is provided with a guide 6 for guiding the sub-printed circuit board 4 in the 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. Therefore, as in the case of FIG. 6, it is not possible to connect the connectors 3 and 5 by moving the sub-printed board 4 in a direction that penetrates the board surface.

[0005]

As described above, in the conventional printed circuit board holding device, when the printed circuit board is moved in the direction of penetrating the plate surface to connect the connectors, the screw must be used. However, there is a problem that the use of this screw increases the cost and increases the number of assembling steps. Also, in the case of connecting the connectors by moving the printed circuit board in the direction along the board surface,
No other component can be placed at the position where the printed circuit board moves on the base, and multiple printed circuit boards are arranged in parallel with each other in the direction orthogonal to the moving direction of the printed circuit board. There is a problem in that it cannot be connected to the board via the connector. The present invention has been made in view of the above, and the printed circuit board can be moved in the direction of penetrating the plate surface for connector connection without using screws, and the printed circuit board can be held in this state. An object of the present invention is to provide a printed circuit board holding device.

[0006]

In order to solve the above problems and achieve the above object, a printed circuit board holding device of the present invention connects a connector fixed to a base to a connector fixed to a printed circuit board. A printed circuit board holding device for holding this printed circuit board on the base in a state where the printed circuit board is moved in a direction penetrating the plate surface to connect the connectors as described above. In the state where the connectors are connected to each other as described above, the base is provided with a guide having tops arranged so as to sandwich the printed circuit board, and the printed circuit board is sandwiched between the guides. In addition, the connector is held by the base by being connected to each other.

[0007]

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described. 1 and 2, reference numeral 8 is 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 printed circuit board 4 is sandwiched, and the tops are arranged so as to face each other.
It is composed of two triangular prisms. The distance between these tops is slightly larger than the thickness of the printed circuit board 4. In FIGS. 1 and 2, the same reference numerals as those in FIGS. 5 to 7 indicate the same parts. The one shown in FIGS. 1 and 2 comprises two main printed circuit boards 2, 2 arranged in parallel, each having a respective connector 3, 3.

In the printed circuit board holding device 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. 1 and rotating it at a predetermined position as indicated by arrow B. , 3, and 5, 5 are connected to each other, and the printed board 4 is held on the base 1 in this state. In FIGS. 1 and 2 described above, the case where the two main printed circuit boards 2 and 2 are arranged in parallel is described.
As shown in FIG. 3, when the other component 9 is disposed on the position where the sub-printed circuit board 4 on the base 1 rotates, the printed circuit board 4 is provided with a notch so that the printed circuit board 4 is cut. Can be rotated.

If another component 9 is provided at the position shown in FIG. 4, the printed circuit board 4 may be rotated,
By moving straight along the plate surface, the printed circuit board 4 can be inserted to the above-mentioned predetermined position while avoiding the component 9. By rotating the printed circuit board 4 at this predetermined position, the connectors 3 and 5 are connected to each other, and in this state, the printed circuit board 4 is held on the base 1. In each of the above embodiments, the connector 3 is fixed to the base 1 via the main printed circuit board 2, but the connector 3 is directly attached to the base 1.
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 plate surface to connect the connectors without using screws, and in this state, the printed circuit board is mounted on the base. Since it is possible to hold the printed circuit board, it is possible to prevent the cost from being increased and the number of assembling steps to be increased by using the screws as in the conventional case. Then, since the printed circuit board is moved in a direction that penetrates the plate surface to connect the connectors to each other, other components can be arranged at the position where the printed circuit board moves on the base,
It is also possible to connect the printed circuit board to a plurality of printed circuit boards arranged in parallel with each other in a direction in which the plate surfaces are orthogonal to each other via a connector.
