The electronic component tray is also used as one assembly.
As such an electronic component tray assembly, for example,
A configuration as shown in FIG. 9 is known.

The electronic component tray assembly 1 shown in FIG.
It is composed of a set of five identical electronic component trays 2. One electronic component tray 2 has a thickness of 0.5
It is formed as a thin plastic molded product of about mm. The electronic component tray 2 includes a bulging portion 3 bulging like a truncated pyramid, and a flange portion 4 formed in a flange shape continuously on the opening side of the bulging portion 3. . Further, the bulging portion 3 has a rectangular flat portion 3a, a frame portion 3b provided so as to surround three sides of the flat portion 3a, and a frame portion 3b continuous with four sides of the flat portion 3a. And a side surface portion 3c protruding to the opposite side. The flange portion 4 is continuous with the side surface portion 3c.

A flat portion 3a of the bulging portion 3 has a concave portion 6 formed of a circular concave portion for accommodating the coin-type battery 5.

The lower surface 27 of the recess 23 is similar to the groove 25a.
It is the same plane as a.

The electronic component tray assembly 10 composed of an arbitrary number of combinations of the four types of electronic component trays 11 to 14 having such a configuration can be used, for example, as follows. As shown in FIG. 4, one coin-type battery 5 representing one embodiment of an electronic component is stored in each of the recesses 23 of the four types of electronic component trays 11 to 14. Therefore, one electronic component tray has a total of 25
The batteries 5 are stored. The electronic component trays 11 to 14 in which the batteries 5 are stored can be used as the electronic component tray assembly 10 by laminating the required number of them in a layered manner.

First, the first electronic component tray 11 is placed on a flat support surface with its flange 22 down. next,
The second electronic component tray 12 faces the first electronic component tray 11 and, as shown in FIG. 6, a bulge opened inside the flange 22 of the second electronic component tray 12. The protruding portion 21 of the first electronic component tray 11 is
Overlaid. As a result, the frame-shaped portion 21b of the first electronic component tray 11 enters the concave side of the bulging portion 21 of the second electronic component tray 12, and the lower surface 23a of the concave portion 23 and the lower surface 27 of the groove 25b The first electronic component tray 11 is in contact with the flat portion 21a.

In this case, when the number of the electronic component trays 11 to 14 to be superimposed is four or less, any combination of the electronic component trays 11 to 14 out of the four electronic component trays 11 to 14 is used. Can be taken. This is because the direction in which the grooves 25a to 25d provided in the respective flat portions 21a extend between the four electronic component trays 11 to 14 is different, and the front portions are made to coincide with each other so that any electronic component tray can be used. Even when the trays 11 to 14 are overlapped, the positions of the concave portions 23 facing up and down all coincide, but the grooves 25a to 25d communicating the concave portions 23 are formed.
Do not overlap each other.

For this reason, the lower surface 27 of the groove 25b of the second electronic component tray superimposed on the upper surface comes into contact with the upper surface of the flat portion 21a of the first electronic component tray placed below. The lower surface 27 of the upper groove 25b is the lower groove 25a.
Never get inside. As a result, the space between the upper and lower electronic component trays is maintained at the predetermined height of the flat portion 21a. This height relationship is the same between the second and third tiers and between the third and fourth tiers of the electronic component tray.

When five or more electronic component trays 11 to 14 are stacked to form the electronic component tray assembly 10, the trays that are distinguished by the difference in the direction in which the grooves 25a to 25d extend are different. Depending on the type, it is necessary to arrange the same type of electronic component trays 11 to 14 so that they do not directly overlap. This is because if the electronic component trays 11 to 14 of the same type are directly overlapped, the grooves 25a to 25d coincide between the upper and lower trays, and the lower surface of the groove located on the upper side enters the groove located on the lower side. This is because there is a danger.

Therefore, the same type of electronic component tray 11
When using the same type of electronic component trays 11 to 1 to prevent the same components from directly overlapping each other.
4 is prevented from overlapping. This prevents the tray from sinking between the upper and lower electronic component trays,
The spacing between the trays can be maintained at an appropriate height.

Next, as shown in FIG. 5, an empty tray 15 containing no batteries 5 is superimposed on the uppermost electronic component tray 14. The empty tray 15 has a role like a lid, and is used by being fitted to the bulging portion 21 of the electronic component tray 14 located at the uppermost stage in the same manner. The battery 5 stored in the recessed portion 23 of the uppermost electronic component tray 14 by the empty tray 15
However, it can be prevented from falling out of the concave portion 23 and falling off.

Thereafter, as shown in FIG. 6, the electronic component tray assembly 10 on which the required number of electronic component trays 11 to 14 are stacked is packaged using a packaging member such as a shrink package 28, for example. And fix them together. As a result, a package of the electronic component tray assembly 10 in which the predetermined number of electronic component trays 11 to 14 are stacked is obtained.

The electronic component tray assembly 10 to which the plurality of electronic component trays 11 to 14 are fixed as described above.
Has a higher strength as a whole than the conventional electronic component tray assembly 1 in which a plurality of electronic component trays 2 are combined, and the gap between the superposed trays 23 of the flat portion 21a of the bulging portion 21 The height can be held at an appropriate height.

More specifically, the shape and structure of the four electronic component trays 11 to 14 are such that grooves are provided in the bulging portion having a large number of concave portions so that the concave portions communicate with each other by the reinforcing wall portion. Since it is the same as the conventional electronic component tray 2 including the points, there is not much difference in the strength of each of the electronic component trays 11 to 14. However, in the four electronic component trays 11 to 14, since the extending directions of the grooves 25a to 25d communicating between the recessed portions 23 are different,
The directions in which the electronic component trays 11 to 14 exert the greatest resistance to external force are different.

That is, since the first electronic component tray 11 has the groove 25a extending in the left-right direction Y, this tray 1
1 is weak against an external force that bends the tray 11 in the front-rear direction X, but can exhibit high strength against an external force that bends the tray 11 in the left-right direction Y. On the other hand, since the second electronic component tray 12 has the groove 25b extending in the front-rear direction X, the second electronic component tray 12 is weak against an external force for bending the tray 11 in the left-right direction Y. High strength can be exhibited with respect to an external force that bends in the direction X.

Similarly, since the third electronic component tray 13 has the groove 25c extending obliquely to the right by 45 degrees, an external force that bends the tray 11 obliquely to the left by 45 degrees. Although weak, the tray 11 can exhibit high strength against an external force that bends the tray 11 obliquely to the right at 45 degrees. Further, since the fourth electronic component tray 14 has the groove 25d extending obliquely to the left at an angle of 45 degrees, the fourth electronic component tray 14 is weak against an external force that bends the tray 11 at an angle of 45 degrees to the right. High strength can be exerted against an external force that tries to bend the tray 11 obliquely to the left at 45 degrees.

Accordingly, in the electronic component tray assembly 10 in which the four electronic component trays 11 to 14 having such a strength relationship are combined, the first force against the external force acting in the left-right direction Y is the first. The electronic component tray 11 exerts a strong resistance, and the second electronic component tray 12 exerts a strong resistance against an external force acting in the front-rear direction X, and an external force acting diagonally to the right. The third electronic component tray 13 exerts a strong resistance, and the fourth electronic component tray 14 exerts a strong resistance to an external force acting in an oblique left direction.

Therefore, any one or two of the four trays 11 to 14 for electronic components exhibit high strength against external forces from all directions and from all directions, and the deflection is caused by resisting the external forces. In order to suppress the occurrence, the strength of the electronic component tray assembly 10 as a whole can be increased.
As a result, the four electronic component trays 11 to 14 can be held in a substantially horizontal state, and the interval (height) between the trays can be held at an appropriate constant value.

Also, four electronic component trays 11 to 14 are provided.
In the above, the grooves 25 a to 25 communicating the plurality of recesses 23 are formed.
Since the shape of the groove 5d, that is, the direction in which the grooves 25a to 25d extend is different, the lower surface 2 of the groove abutted on the flat portion 21a
7 does not fit into the groove provided in the flat portion 21a, and is always held on the flat portion 21a. As a result, the interval between the electronic component trays can be kept constant, and the batteries 5 housed in the recesses 23 can be held in a good posture in the horizontal direction.

FIG. 7 shows a second embodiment of the present invention. The electronic component tray assembly 30 shown in the second embodiment is configured by a combination of two electronic component trays 11 and 31. One electronic component tray 11 is the first electronic component tray in the first embodiment described above, and the other electronic component tray 11 is the fifth electronic component tray. 31 is different only in the position of the groove and the reinforcing wall formed on both sides of the groove. Therefore, the description of the electronic component tray 11 will be omitted, and the electronic component tray 31 will be described in detail.

The electronic component tray 31 has a size, a shape,
The number and positions of the recesses are the same as those of the electronic component tray 11, and the trays 11 and 31 can be overlapped with each other. The groove 32 in which the electronic component tray 31 is different from the electronic component tray 11 holds a parallel state with respect to the groove 25a of the first electronic component tray 11 and is offset rearward in the front-rear direction X by a predetermined length e. It is provided. Reinforcing walls 33, 33 are formed on both sides by the groove 32. Groove 32 which is the space between reinforcing walls 33, 33

Another configuration of the electronic component tray 31 is as follows.
This is the same as the electronic component tray 11. That is, the electronic component tray 31 includes the bulging portion 21 and the flange portion 22, and the bulging portion 21 has the flat portion 21 a, the frame portion 21 b, and the side surface portion 21 c. The flat portion 21a is provided with a plurality of concave portions 23 (25 in this embodiment), and the lower surface 23a of each concave portion 23 and the lower surface 34 of the groove 32 are suspended downward to be the same as the flange portion 22. Set to height. Further, a through hole 24 penetrating to the lower surface side is provided on the bottom surface of each concave portion 23.

FIG. 8 shows an embodiment in which a plurality of electronic component trays 11 and 31 are used to form an electronic component tray assembly 30 in a cross section in the front-rear direction X. . The first electronic component tray 11 and the fifth electronic component tray 31 are alternately overlapped,
A first electronic component tray 11 is arranged at the lowermost and uppermost stages.
