Description

[Detailed Description of the Invention] This invention relates to an improvement of a plug-in unit storage device.

Conventionally, in a plug-in unit storage device, a lightweight plug-in unit (1 in Fig. 1 to be described later) made of a printed wiring board (hereinafter abbreviated as a PC board) etc. is placed in a storage case (2 in the same figure).
), as shown in FIG. 1, a groove 4 corresponding to the thickness of the PC board 3 is formed on the guide plate 5, and the PC
After inserting both ends of the plate 3, slide it into the storage case 2.
It is designed to be attached to a connector terminal (not shown) provided at the rear of the device.

However, some plug-in units have large and heavy electronic components such as transformers and large-capacity capacitors mounted on the chassis.

Such a heavy plug-in unit generally has a plurality of chassis or printed wiring boards 7a and 7b as shown in 6 in FIG.
They are connected and integrated with intervening members 8a and 8b at appropriate intervals.

The intermediate members 8a, 8b are formed with protrusions 9a, 9b for fitting into grooves provided on the guide plate.

However, when the intermediate members 8 a , 8 b and the protrusions 9 a , 9 b are formed by, for example, sheet metal processing, the protrusions 9 a , 9 b are formed into the grooves for the lightweight plug-in unit 1 (first It is difficult to form it into a narrow shape so as to fit it into 4) in the figure due to its accuracy.

On the other hand, when the intermediate members 8a, 8b and the protrusions 9a, 9b are integrally formed by die-casting, the narrow groove portion 4
It is difficult to obtain sufficient strength to support the heavy plug-in unit 6.

Therefore, in order to accommodate the heavy plug-in unit 6, as shown in FIG.
It is unavoidable to form a wide groove 11 in the guide plate 10 so that the protrusions 9a and 9b fit therein.

In other words, the conventional plug-in unit storage device
As shown in the figure, a plurality of types of guide plates 5 and 10 with different groove widths are provided in the storage case 2, and a lightweight plug-in unit 1 (
(Fig. 1) and the heavy plug-in unit 6 (Fig. 2) are housed separately in each of the guide plates 5, 10.

Therefore, in such a device, the heavy plug-in unit 6 and the lightweight plug-in unit 1 cannot be stored using the same guide plate, resulting in a low storage density.

Further, even if the plug-in units should normally be housed adjacent to each other, they have to be separated due to the difference in weight, resulting in the problem of complicated wiring between the connector terminals.

Furthermore, since a plurality of guide plates must be manufactured depending on the weight of the plug-in unit, it is impossible to standardize the guide plates, leading to an increase in the price of the device.

This idea was devised in light of the above circumstances, and its purpose is to allow multiple types of plug-in units of different weights to be stored with high density and precision, while also being able to standardize the guide plate. To provide a simple and inexpensive plug-in unit storage device.

The invention will now be described with reference to embodiments shown in the drawings.

Note that the same parts as in the conventional example are given the same reference numerals and detailed explanations will be omitted.

In FIG. 4, a plurality of guide plates 12 are arranged within the storage case 2 at predetermined intervals in the direction of gravity (vertical direction of the storage case 2), and these guide plates 12 provide a plurality of stages. A storage room for plug-in units is provided.

Here, the plug-in units include a relatively lightweight first plug-in unit 1 in which a lightweight electronic component 13 is attached to a PC board 3 as shown in FIG. A heavy second plug-in unit 14 is also applied.

This second plug-in unit 14 is equipped with heavy electronic components (fifth
Chassis 7 a and 7 b to which 15) in the figure are attached are connected and integrated with intermediate members 16 a and 16 b interposed.

And intermediate members 16a, 16. Two protrusions 17 a and 17 b are integrally formed on b by die-casting, for example, and constitute an end portion of the second plug-in unit 14 .

As shown in FIG. Wide second groove portions 18 are alternately arranged at predetermined intervals.

The width of the first groove portion 4 is determined to be approximately equal to the thickness of the PC board 3 of the first plug-in unit 1.

Further, the width of the second groove portion 18 is determined to be approximately equal to each width of the protruding portions 17 a and 17 b provided on the intermediate members 16 a and 16 b of the second plug-in unit 14 , and The distance between the second groove portions 18 is set to be approximately equal to the distance between the protrusions 17 a and 17 b of the second plug-in unit 14 .

According to the plug-in unit device configured in this way, the first plug-in unit 1.1 fits both ends of the PC board 3 into either of the first grooves 4 provided in the guide plate 12. By inserting it, it is reliably stored in the desired position of the storage case 2.

On the other hand, the second plug-in unit 14 inserts two protrusions 17 a and 17 b into two adjacent grooves of the second groove 18 provided in the guide plate 12 . As a result, it is reliably stored at a desired position in the storage case 2.

That is, the first plug-in unit 1 and the second plug-in unit 14 are connected to the same guide plate 1 of the storage case 2.
2, they will be stored in a mixed manner.

Therefore, according to the embodiment device described above, the narrow first groove 4 and the second groove 18 wider than the first groove 4 are formed on the same surface of the guide plate 12. As a result, the lightweight first plug-in unit 1 and the heavy second plug-in unit 14 can be mixedly stored on the same guide plate 12 of the storage housing 2, and the storage density can be improved. can.

Furthermore, since it is possible to make all the plurality of guide plates 12 the same, the guide plates 12 can be standardized, and the cost of the apparatus can be reduced.

Further, the protrusions 17a and 17b of the heavy second plug-in unit 14 are die-cast to form the intermediate member 16.
Since it is formed integrally with a and 16b and has a wide shape, it is possible to store it in the guide plate 12 with high precision, and also to obtain sufficient mechanical strength at the degree of storage.

Note that this invention is not limited to the above embodiments.

For example, the intermediate member 16 of the second plug-in unit 14
The state in which the protrusions 17a and 17b formed in the shapes a and 16b are inserted into the second groove 18 is as shown in FIG. Each of the protrusions 17 a , 17 a and 17 b of the unit 14
, 17b. Alternatively, as shown in FIG.
The outer portions of the two may be fitted together.

Furthermore, the protrusion portion 17 a of the second plug-in unit 14
, 17b may be three or more in addition to two, or may be one as shown in FIG. 6C.

Furthermore, the arrangement order of the first groove portions 4 and the second groove portions 18 in the guide plate 12 does not have to be alternate one by one.
Two or more wires may or may not be alternated.

In short, any method may be used as long as at least one first groove 4 and at least one groove wider than the first groove 4 are provided on the same surface of the guide plate.

Furthermore, the number of second groove portions 18 is not limited to one type as in the embodiment, but may be two or more types.

Thereby, three or more types of plug-in units having different weights can be mixed and housed on the same guide plate according to their weights.

Furthermore, as a second plug-in unit, a chassis equipped with heavy electronic components and a PC board or chassis equipped with light electronic components are connected by an intermediate member, that is, a chassis equipped with heavy electronic components and the first plug-in unit. An integrated unit with the plug-in unit 1 may also be used.

Furthermore, the guide plate may be arranged in a direction perpendicular to the direction of gravity.

In this case, each plug-in unit is housed in the housing housing horizontally rather than vertically as in the embodiment.

In addition, the structure of each plug-in unit, the size and shape of the storage case 2, the number of guide plates 12 installed in the storage case 2, etc. can be modified in various ways without departing from the gist of this invention. .

As detailed above, according to this invention, a first groove portion having a predetermined width and a second groove portion wider than the first groove portion are formed on the same surface of the guide plate disposed inside the storage case. respectively, and a lightweight first plug-in unit is attached to the first plug-in unit above.
In addition, the second plug-in unit, which is heavier than the first plug-in unit, is guided and regulated by the second groove and stored, so that multiple types of different weights can be stored. Since plug-in units can be mixed and stored on the same guide plate, plug-in units can be stored with high density and precision.Moreover, the guide plate can be standardized, creating a simple and inexpensive plug-in unit storage device. can be provided.
