る。In word processors, personal computers, workstations, etc., the mounting structure of the boards inside the main body is such that an expansion board is connected to the main board and an option board is connected to the expansion board, or the main board and options are connected to the expansion board. Expandability was achieved by connecting the boards. From the point of view of the functional expandability of the device, it is necessary to mount multiple option boards, so the mounting structure of the main board, expansion board, and option board cannot be achieved with a two-dimensional (two-dimensional) arrangement, but with a three-dimensional arrangement. It was necessary to take a (three-dimensional) arrangement. For this reason, as shown in FIG. 5, a method is used in which the horizontally arranged main board 2 and the plurality of option boards 3 are connected via connectors on the vertically erected expansion board 1. In order to three-dimensionally arrange these three types of boards, the main frame 4. The mounting structure uses a substrate holding method using an intermediate base 6 or the like.

置が合わなくなる。Conventionally, in this mounting structure, from the viewpoint of workability, the expansion board 1 was inserted into the plurality of board guides 5 of the main frame 4 and fixed with screws 10, and the intermediate base 6 was fixed with screws 10 from above. The main board 2 is inserted into a plurality of board guides 5 of the main frame 4 from the rear, slid forward, and connected to the connector 7 on the expansion board 1. The option board 3 is also connected to the connector 7 on the expansion board 1 in a similar manner. Usually, the dimensions of the main frame 4 have some play so that the board can be moved smoothly. However, unless this play is reduced, the connector 7 of the expansion board 1 fixed to the main frame 4 will not be aligned with the connectors 8 and 9 of the main board 2 and option board 3.

本数が多くなってしまう。In general, connectors are provided with a tapered portion at an appropriate angle of attack on their housing portions so that they can be easily inserted into each other, but smooth connection is difficult if there is no relative movement between the boards. In order to ensure the connection without relative movement between the boards, precision in assembling the main frame 4 and the intermediate base 6 is required. Further, since the main frame 4 and the intermediate base 6 are required to have strength after assembly, the number of screws 10 increases.

問題があった。特に、メイン基板とオプション基板の仲
介となる拡張用基板の取り付は精度が問題であった。The above-mentioned conventional technology has problems in the dimensional accuracy of frames that realize a three-dimensional board mounting structure and in the workability of screw tightening. That is, after inserting the main board 2, the main frame 4 and the intermediate base 6 are positioned while being inserted into the plurality of board guides of the intermediate base 7, and then fixed with the screws 10, which poses a problem in assembly workability. Ta. In addition, there are problems with dimensional accuracy after assembly, and when the user mounts the option board 3, the connectors 7 on the expansion board 1 and the connectors 9 on the option board 3 may not align, resulting in poor workability and mounting problems. There was a problem with the stress placed on the subsequent board. In particular, accuracy was a problem when attaching the expansion board, which acts as an intermediary between the main board and the option board.
本発明の目的は、取り付は寸法精度を厳しくしなくとも
取り付は可能な基板の実装構造を提供することにある。An object of the present invention is to provide a board mounting structure that allows mounting without strict dimensional accuracy.
上記目的は、拡張用基板の取り付けに自由度を持たせる

。Since the held expansion board has a large degree of freedom, when inserting the main board and option board, it can be moved within the range of play between the guide portions of the main frame and the intermediate base.
以下、本発明の一実施例を図によって説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

が可能な必要最低限の大きさの角穴１１が設けである。FIG. 2 is a perspective view showing how to assemble it. FIG. 3 is a partially enlarged view. An intermediate base 6 is connected and fixed to the main body main frame 4 by a connecting means such as spot welding, and has a box-like structure. This provides the strength necessary to hold each board during assembly and disassembly of the product, transportation, and use by the user. The intermediate base 6 is provided with a square hole 11 of the minimum necessary size through which the expansion board 1 can be passed vertically from above.

あればスムーズな接続が可能となる。A slit 12 is provided in the square hole 11 to serve as a guide for the main board. The main frame 4 and the intermediate support plate 13
A plurality of substrate guides 5 are installed at positions corresponding to the slits 12.
This is provided. The expansion board 1 is inserted vertically into the intermediate base 6 from above using the slit 12 as a guide. The expansion board l stops at the position where it contacts the main frame 4 due to its own weight, and becomes movable in two directions within the constraint range of the guide. Next, when the main board 2 is inserted into the main frame 4 along the guide part by horizontal sliding, the connectors 7 and 8 of the main board 2 and the expansion board 1 are moved by the two-direction movement of the expansion board described above. 6. In other words, the connectors have a tapered part with an appropriate angle of attack on the housing part so that they can be easily inserted into each other, but this taper part alone cannot absorb the difference. Even if there is a misalignment between the connectors, a smooth connection can be achieved if there is relative movement between the boards.

When inserted into the main frame 4 along the guide part by sliding it horizontally, the connection between the option board 3 and the connectors 7 and 9 of the expansion board 1 is made smooth by the two-direction movement of the expansion board mentioned above. can be done.

工寸法精度に厳しさは余り要求されない。Since the expansion board 1 is held in a state with a degree of freedom, the precision of machining dimensions of pressed products such as the main frame and intermediate base is not required to be very strict.

まり、ガイドの拘束範囲内で２方向に移動可能となる。FIG. 4 shows another embodiment according to the present invention, in which the insertion direction of the expansion board 1 is changed. A rectangular hole 11 of the minimum required size is provided on the side surface of the main frame 4, through which the expansion board 1 can pass in an upright state. A slit 12 is provided in the square hole 11 to serve as a guide for the main board. A slit 12 is provided in the main frame 4 and the intermediate support plate 13.
A plurality of substrate guides 5 are provided at positions corresponding to. The expansion board 1 is inserted laterally using the slit 12 as a guide. The expansion board 1 stops at the stopper 14 and is movable in two directions within the constraint range of the guide.

を達せられる。However, since the lateral movement of the expansion board 1 can only be restrained in one direction by the stopper 14, it is necessary to prevent the expansion board 1 from being pulled out using external design parts such as the cover 15 attached to the main frame 4. Further, the method for preventing the extension board 1 from being removed is not limited to the attachment of the cover 15, and the same purpose can be achieved even by attaching a separate part for exclusive use.

ても同様である。In the above, the expansion board is vertical and the main board and option board are horizontal, but the horizontal and vertical directions of the boards indicate the relative positional relationship between the boards and are not absolute. Further, in the embodiment, the insertion of the option board 3 is described as being performed by assembly at the manufacturer, but the same applies even if the installation is performed by the user in the field.

In addition, since the expansion board can be given a degree of freedom, connections between boards can be made smoothly using connectors.
Moreover, it has the effect of relieving stress applied to the board and connector after connection.
