Description

[Detailed explanation of the invention] (a) Industrial application field The present invention can be used for storing various plate-like objects, but it is especially useful for the assembly process of printed wiring boards (hereinafter referred to as boards), and for storage and transportation. The present invention relates to a rack that can be used alone or together with a case such as a removable case for storing circuit boards.

(b) Prior Art Conventionally, various enclosures, rack-shaped partition frames, etc. have been used in the assembly process, storage, and transportation of circuit boards to store or arrange circuit boards during or after assembly. They are used in a wide variety of ways, but apart from very special forms, they can be roughly classified into three types. That is, the first form is a dedicated case whose interior is fixed or removable and partitioned into predetermined dimensions by a partition frame or partition plate, and can be used for substrates of any shape, whether regular or irregular. It is also suitable for mass production. The second type is a dedicated case that matches the dimensions of the board, with a guide rail for board storage on the inside surface.The box itself has the advantage of being lightweight, making it possible to store standard boards for a long time. This is suitable for stable production. The third form that remains is one in which a separately prepared bookend-like rack with a number of partition plates is placed inside a general-purpose case (for example, a plastic case) whose purpose is not specified. It can be used for both mass production and small quantity production. Incidentally, the rack has a shape as shown in Fig. 5 (plan view), and in the figure, the rack 1 consists of a plurality of partition plates 3 arranged in parallel at regular intervals on the upper surface of a rectangular plate-shaped base part 2. Generally, it is often molded from plastic for ease of manufacture.

(c) Problems to be solved by the invention In the case of the above-mentioned structure for housing the board, that is, the first form described above, which is a special case with a partitioned interior, the dimensions of the internal partitions are not specified. As a result, it is difficult to adapt to a high-mix, low-volume production format, and the market lifespan is particularly short, and home appliance assembly factories are subject to rapid model changes, especially for the production of stable production models. It was extremely inefficient for use in related cooperating factories, etc., which were difficult to secure. The second form, a dedicated case with a guide rail for board storage on the inner surface, is suitable for boards for industrial equipment whose external dimensions are not likely to change even when the model is changed, but other types It is extremely difficult to convert to Therefore, the third form, a bookend-shaped rack that is placed in a general-purpose case, is extremely simple, economical, and has a wide range of applications because it can be used with any case. However, the size of the case used in combination must have an internal dimension that is a multiple or more of the size of the rack, and the number of boards that can be stored is similarly limited, so it is not necessarily easy to use in all aspects. I couldn't say that.

This invention was devised in order to solve the problems in the various conventional circuit board storage structures as described above, and can be applied to general-purpose enclosures of all sizes, and can be used in both mass production and small quantity production. The purpose is to provide a rack that can be easily used without any hassle.

(d) Means for solving the problem The problems described above are solved by the rack structure consisting of a plate-shaped or frame-shaped base part and a plurality of parallel partition plates installed perpendicularly on the surface of the base part. The base portion is present only on one side from approximately the center in the width direction of the partition plate, and one or more racks at a constant pitch are provided on the inner side of the base portion so that it can be combined with another rack of the same type. The present invention is solved by a rack characterized in that it has interfitting parts. If the shape of the base part is approximately crank-shaped, some restrictions will be placed on the combined dimensions, but stability will be increased when placed, and this is particularly suitable when used alone.

(e) Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

Figures 1 to 3 show the rack of the present invention. In the figure, 1 is the rack, in which a plurality of parallel partition plates 3 are vertically attached to the upper surface of a plate-like crank-shaped base part 2. The inner side of the base part 2 has an interfitting part 4 consisting of a convex part 4a and a concave part 4b for combination with another rack of the same type. For example, when combining with the mutually fitting part 4' of another rack 1' at a specific position as shown in Fig. 2 (for example, when connecting at 1/2 the total length), only one set is required. If you want to adjust the connection length at a finer pitch, for example, half the distance between the partition plates 3, as shown in Figure 3, two concave portions 4b are provided between the partition plates 3. That's fine. At this time, the convex portions 4a that form a pair with the concave portions 4b may be provided at only one at the extreme end as shown in the figure, or may be provided in the same number and at the same pitch as the concave portions 4b.

FIG. 4 shows another embodiment of the present invention, in which the base part 2 of the rack 1 is replaced by a partition plate 3.
The interfitting parts 4 for interconnection are arranged at a constant pitch on the inner side of the base part 2, as in the previous embodiment, but in this embodiment. In the case of , another similar rack 1'
Although there are a plurality of concave portions 4b because they are combined facing each other in a direction reversed by 180 degrees, only one convex portion 4a is provided at the extreme end due to the arrangement space.

In addition, in the above two embodiments, the mutual fitting part 4
Although each of these is constructed with a round convex portion 4a and a concave portion 4b, other shapes, such as a rectangular shape or a triangular shape, can of course be applied. As for the material forming the whole, conductive resin is most suitable because static electricity is averse depending on the type of semiconductor mounted on the printed wiring board.

(f) Function As shown in Figure 2, the mutually fitting parts 4 and 4' of the two racks 1 and 1' are fitted together to connect them. 3 are in close contact with each other through mutually fitting parts 4 and 4'.
Since the positions of the partition plates 3 and 3 are set, a substantially constant partition interval is ensured, although there is a shortage by the thickness of the partition plate 3 or 3'.

In the case of FIGS. 3 and 4, it is only necessary to select an arbitrary part from among the plurality of mutually fitting parts 4 according to the desired length, and connect them by fitting. It is possible to achieve a connection length of In addition, since the interconnecting portions 4 are provided at a pitch that is 1/2 of the mutual spacing between the partition plates 3, the mutual spacing between the partition plates 3 should be reduced to 1/2 of the original dimension only in the overlapping connection portions. You can also do it.

(g) Effects As described above, according to the present invention, by providing the mutually fitting part consisting of the convex part and the concave part in the base part, it is possible to connect each other to any length, and it can be used as a standalone part. Of course, it is possible to use it, and it has become possible to provide a very convenient rack that can be housed and placed in a case of any size and utilize the space inside the case without wasting it.
