On the other hand, a card plastic 23 (see FIG. 4) and the like are mounted on both the left and right sides near the front portion F (front side). Further, the front portion F is made of metal in a standing state with respect to the board surface 21. The panel 24 is attached.
[0024]
The panel 24 has various names printed on the board surface 21 constituting indicators for displaying various functions for display guidance of LEDs (not shown) and operation guidance such as operation switches. Depending on the type of printed circuit board unit, its width (W) or thickness may differ slightly.
[0025]
That is, the slot of the electronic device described above is usually perforated in a plurality of sizes according to the type and function of the printed circuit board unit to be inserted. For example, in this embodiment, the standard unit width (hereinafter referred to as the minimum unit width) is used. , This is referred to as “1 slot”) and slightly wider than that (hereinafter referred to as “2 slots”).
[0026]
On the other hand, the printed circuit board unit 2 is provided with panels of two different widths corresponding to these slots. For example, when the slot in the electronic device 7 is 1 slot, it has a panel that matches the opening width (hereinafter referred to as “1 slot size”), and in the case of 2 slots, A panel having a panel corresponding to the opening width (hereinafter referred to as “2-slot size”) is prepared.
[0027]
The printed circuit board unit 2 has a case where the size of the panel 24 (the size corresponding to the width (W) in FIG. 2) differs depending on the type (1 slot size and 2 slot size) used. However, in consideration of compatibility with the electronic device 7, a common connector 22 is used for the rear portion R. Therefore, the dimensions at these rear portions R (the portion corresponding to the width (w) in FIG. 2) are the same for both the 1-slot size and the 2-slot size.
[0028]
As shown in FIG. 1, the box body 3 is formed of a paperboard material having an appropriate strength, for example, corrugated cardboard, etc., and is formed of a hollow box shape having a lid portion whose upper portion can be opened. The box body 3 of the present embodiment can store the printed circuit board unit 2 in a safe state by setting the receiving member 4, the printed circuit board unit 2 stored in the insulating bag 5, and the pushing member 6 in order from the bottom.
[0029]
Therefore, the printed circuit board unit 2 is supported and supported in the box body 3 while absorbing the impact from below by the receiving buffer member 4 provided immediately below the printed circuit board unit 2, and It is fixed and held firmly.
[0030]
As shown in FIG. 5, the receiving member 4 is made of an appropriate material having an impact absorption property, for example, a polystyrene foam resin, so that the receiving member 4 fits snugly inside the box body 3 (in three directions of height and width) without a gap. It is formed in a substantially rectangular shape, and a recess 41 for mounting the printed circuit board unit 2 is provided at the center. Around the recess 41, when the printed circuit board unit 2 is mounted, an upright standing wall facing the recess 41 is provided to fix and protect the printed circuit board unit 2 from the front, rear, left and right directions. A substantially square-shaped surrounding portion 40 having 42 is formed.
[0031]
Among the four standing walls 42 surrounding the recess 41 in this way, the standing wall 42 on the front side in FIG. 5 is directed toward the center of the recess 41 on the center and both sides of the center wall. Convex portions 43A and 43B that project from each other are formed.
Among these, the pair of convex portions 43B on both sides are provided to be separated by a predetermined distance L1, and a pressing member 6 described later is fitted between the pair of convex portions 43B without a gap. .
[0032]
On the other hand, a convex portion 43C is provided on a part of the standing wall 42 on the back side facing the standing wall 42 on the near side so as to protrude substantially half the length of one side. In particular, since the convex portion 43C is formed in a portion from the upper surface of the surrounding portion 40 to the lower middle portion that does not reach the concave portion 41, the portion between the convex portion 43C and the lower concave portion 41 is missing. The horizontal hole 44 is substantially formed. In addition, the rear portion R of the printed circuit board unit 2 enters and is locked in the lateral hole 44.
[0033]
Further, the receiving member 4 faces the front portion F of the printed circuit board unit 2 so that the printed circuit board unit 2 can be firmly fixed when the printed circuit board unit 2 is mounted in the recess 41. A pushing groove 45 for pushing a pushing member 6 (described later) and fixing it in an upright state is formed in the recess 41 between the standing wall 42 on the near side and the length L2.
[0034]
Of these four standing walls, a concave portion 46 is formed in a corner portion between the pair of convex portions 43B provided on the front side standing wall 42 and the vertical walls 42 on the left and right sides. The card plastic attached to the printed circuit board unit 2 is configured to enter the space.
[0035]
Further, in the receiving member 4 of the present embodiment, a foamed polystyrene resin having shock absorption is used as a forming material, but the invention is not particularly limited thereto, for example, cardboard formed along an appropriate development view, etc. May be appropriately assembled and assembled into a similar shape. In addition, the receiving member 4 of the present embodiment may be formed of an appropriate antistatic material, such as polyethylene, and various electronic devices mounted on the printed circuit board unit 2 mounted on the receiving member 4. It is possible to effectively prevent the occurrence of unnecessary troubles such as electrostatic breakdown due to static electricity on parts.
[0036]
The insulating bag 5 is intended to protect the printed circuit board unit 2 from the outside and at the same time, particularly to prevent static electricity. In the present embodiment, the insulating bag 5 is made of an insulating sheet material such as polyethylene or vinyl. It is formed in a shape. The printed circuit board unit 2 is configured to be set as it is together with the insulating bag 5 on the receiving member 4 while being housed in the insulating bag 5.
[0037]
The pushing member 6 is pushed between the receiving member 4 and the front part F of the printed circuit board unit 2 so as to sandwich the front part F of the printed circuit board unit 2 between the recess 41 and has a shock absorbing property. It is formed in a columnar shape having a substantially L-shaped cross section as shown in FIGS. 8 and 9 by using an appropriate material such as a polystyrene resin. In particular, the pushing member 6 is also formed of the same material as that of the receiving member 4, and similarly, unnecessary troubles such as electrostatic breakdown due to static electricity occur with respect to the electronic components on the printed circuit board unit 2 side. Can be effectively prevented.
The pushing member 6 is provided with leg portions (which constitute a pushing portion) 61 and 62 which are pushed into and fitted into the pushing groove 45 provided in the recess 41 so as to protrude 90 degrees from each other. Yes. Furthermore, the leg portions 61 and 62 are formed in a tapered shape with the corners of the tip portions cut off, so that the insertion operation can be performed smoothly.
[0038]
These leg portions 61 and 62 are both formed to have a lateral width L2 so that they can enter the push groove 45 without any gap, but the leg portion 62 is formed to protrude longer. . In addition, as shown in FIG. 9, these leg portions 61 and 62 are opposed to each other and constitute pressing surfaces 61A and 62A described later.
[0039]
10A and 11B, the pressing surface 61A is formed between the front portion F of the printed circuit board unit 2B having a two-slot size, specifically the panel 24 and the recess 41 from the vertical direction. Hold firmly.
[0040]
Incidentally, as shown in FIG. 4, the width (W2) of the panel 24 is larger than the width (W1) of the panel 24 of the 1-slot size printed circuit board unit 2A. Accordingly, the gap (H2) between the pressing surface 61A and the recess 41 when sandwiching the panel (width; W2) 24 having a two-slot size as shown in FIG. 10 is a one-slot size as shown in FIG. It is necessary to ensure a larger size than the gap (H1) when sandwiching the panel (width; W1). For this reason, as described above, the leg portion 62 is formed longer than the leg portion 61.
[0041]
On the other hand, as shown in FIGS. 8 and 9, the pressing surface 62 </ b> A firmly holds the panel 24 of the printed circuit board unit 2 </ b> A having a 1-slot size between the recess 41 and the vertical direction. Since the width of the panel 24 of the slot size printed circuit board unit 2A is smaller than the width of the panel 24 of the printed circuit board unit 2B having 2 slots, the length between the slot 41 and the recess 41 can be small. The length of is formed short.
[0042]
Further, even when the printed board unit 2B of 1 slot size or 2 slot size is sandwiched in the pushing member 6, as shown in FIG. 7, for example, it is firmly fitted between the convex portions 43B. In order to hold (fix) the receiving member 4, a pair of protruding portions 63 that slightly protrude in the left-right width direction from the leg portions 61 and 62 are provided.
[0043]
That is, as shown in FIG. 6, the width of the left and right protrusions 63 is formed to a length L1 that exactly matches the (separation) distance L1 (see FIG. 5) between the pair of protrusions 43B. Further, as shown in the figure, the protruding portion 63 is in a flush state without protruding from the surface of the leg portion 61, but protrudes from the surface of the leg portion 62 by a height P.
[0044]
As a result, as shown in FIGS. 7 and 9, when the printed circuit board unit 2B of 1 slot size is sandwiched, the central portion of the leg portion 61 and the standing wall 42 are locked (in one place). Yes.
[0045]
On the other hand, as shown in FIG. 10, even when the printed circuit board unit 2B having a two-slot size is sandwiched, the central portion of the leg portion 62 and the standing wall 42 are engaged (in one place) as in the case of the one-slot size. Stop. By the way, in this 2 slot size, since the pushing member 6 stands upright from the recess 41, there exists a possibility that it may be in an unstable state compared with the case of 1 slot size. However, in this case, as shown in FIG. 11, the protrusions 63 projecting to the left and right of the leg portion 62 are also locked to the standing wall 42 at two locations, and the pushing member 6 is convenient for the standing wall 42. Locked in three places. Accordingly, even when the printed circuit board unit 2B having a 2-slot size is sandwiched, the pushing member 6 can stand upright in a stable state.
[0046]
Next, the procedure and operation when actually packaging the printed circuit board unit 2 using the packaging box according to the present embodiment will be described.
[0047]
A. When packing 1 slot size printed circuit board unit 2A:
(1) In FIG. 1, first, the receiving member 4 is prepared in a state before being set inside the box body 3.
(2) Next, the article to be packed 2 is placed in the insulating bag 5.
[0048]
{Circle around (3)} Then, the printed circuit board unit 2 </ b> A together with the insulating bag 5 is set in the recess 41 of the receiving member 4.
However, in this case, the rear portion R (see FIG. 2) side of the printed circuit board unit 2A is inserted into the lateral groove 44 of the receiving member 4 from the horizontal direction first, and then the front portion F side is received. Mount in the recess 41 of the member 4.
[0049]
{Circle around (4)} When the printed circuit board unit 2A is mounted on the receiving member 4 together with the insulating bag 5, the pushing member 6 is then inserted into the gap between the article 2 and the receiving member 4 from the A direction ( As shown in FIG. 6, it is pushed in, and the lower leg portion 61 is inserted into the pushing groove 45 of the receiving member 4 and fitted.
[0050]
(5) In this way, the pushing member 6 has the leg portion 61 inserted and fitted into the pushing groove 45 of the receiving member 4, but at the same time, as shown in FIG. The front side surface) is pressed against the convex portion 43A, and the short side (the left and right side surfaces in FIG. 7) is firmly fixed to the convex portion 43B.
Therefore, as shown in FIGS. 8 and 9, the front portion F of the printed circuit board unit 2A can be firmly fixed between the recess 41 and the pressing surface 62A.
As a result, the printed circuit board unit 2 </ b> A is such that the upper and lower end portions of the front part F and the rear part R are firmly fixed to the receiving member 4.
[0051]
(6) Finally, the receiving member 4 that firmly holds the printed circuit board unit 2A is set in the opened box body 1 and the lid of the box body 3 is closed and the adhesive tape is closed. If it is closed, the printed circuit board unit 2A can be safely stored and packed.
[0052]
B. When packing the printed circuit board unit 2B of 2 slots size:
In this case as well, the printed circuit board unit 2B having the large front portion F can be safely secured by using the same box body 3, receiving member 4, and insulating bag 5 by the operations (1) to (6). In this case, the pushing direction of the pushing member 6 in (4) is different.
[0053]
That is, in this case, the pushing member 6 is pushed in the direction B in FIG. 6, and the leg portion 62 is inserted and fitted into the pushing groove 45 of the member 4.
[0054]
Therefore, in (5), the pushing member 6 has the leg portion 62 inserted and fitted into the pushing groove 45 of the receiving member 4. At this time, as shown in FIGS. 10 and 11, the central portion of the back side (right side in FIGS. 10 and 11) on the long side of the pushing member 6 is pressed against the convex portion 43 </ b> A and the short side (FIG. 11, the front and back surfaces) are firmly fixed in a state of being sandwiched between the convex portions 43 </ b> B. The situation here is the same as that of the printed circuit board unit 2A of one slot size.
[0055]
However, in the case of the printed circuit board unit 2B having the two-slot size, the protrusions 63 on both the left and right sides are in close contact with the standing wall 42. Will be. For this reason, even if it is the pushing member 6 in the upright state higher than the case of the printed circuit board unit 2A, it can stand up with respect to the receiving member 4 in the firmly stable state.
[0056]
As a result, the printed circuit board unit 2B can firmly fix the two-slot size front portion F between the pressing surface 61A of the pressing member 6 and the recess 41.
[0057]
In the present embodiment, the printed circuit board unit 2 that is an object to be packaged mounted on the receiving (buffer) member 4 is not provided with any appropriate buffering member on the printed circuit board unit 2. You may make it cover with a cushion member (or cover member). The cushion member may have a structure in which air is filled in a sheet-shaped synthetic resin formed into a hollow bag shape, or a thick paper material such as a cardboard material is used.
