Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 and 2 are plan views of the article storage trays 1, 1 '(hereinafter simply referred to as trays) of the present invention. Referring to FIG. 1, a tray 1 has a rectangular outer shape, and has 24 recesses 2 for accommodation arranged in a matrix. The tray 1 is formed of a polystyrene resin, and each recess 2 is defined by partitions 4 and 6.
Further, the outer periphery is surrounded by an outer wall 8 higher than the partition walls 4 and 6. The bottom surface 20 of each concave portion 2 is flat and low, and the convex portion 10 is formed substantially at the center upper portion from the substantially center to the right. The projection 10 has a substantially P shape, and a projection 12 is formed downward in the figure.

In each recess 2, a connector (article) 50 having a substantially U-shaped outer shape is arranged. In the figure, two connectors 50 are exemplarily accommodated in the recess 2, but actually 24 connectors 50 are accommodated. The connector 50 has a substantially U-shaped housing 52 made of synthetic resin, and a pair of metallic latch arms 54 projecting from both ends of the housing.

Next, another tray 1 'will be described with reference to FIG. The tray 1 'is manufactured by the same material and manufacturing method as the tray 1. In the description, similar parts will be described with reference signs appended with '. The recesses 2 ′ of the tray 1 ′ are formed in the same positions and in the same arrangement and in the same number as the recesses 2. Each recess 2 ′ is defined by partition walls 4 ′ and 6 ′, and a flat bottom 20 ′ of the recess 2 ′
0 'is formed. The only difference between the tray 1 and the tray 1 'is the shape of the projection 10'. The outer shape of the convex portion 10 ′ is formed in an inverted P shape from the upper center to the left side,
It has a projection 12 'similar to the projection 12. This projection 12 '
Is the same as the position of the projection 12. The same connector 50 is exemplarily arranged in the concave portion 2 '. Tray 1 and 1 '
Have cavities in the same mold and are molded simultaneously. This eliminates the need to prepare separate molds.

FIG. 3 is a partially enlarged plan view of the tray 1. A raised portion 14 is formed from the partition wall 6 and the outer wall 8 according to the shape of the outer end of the connector 50.
Rattling in the left-right direction is prevented. The connector tines 56 of the contacts provided on the housing 52 are arranged on the connector 50 so as to be exposed along both sides of the housing 52. The row of tines 56 is interrupted at the center slightly to the left. The projection 12 of the projection 10 abuts on the interrupted portion 58 to prevent the connector 50 from moving upward. The downward movement of the connector 50 is restricted by the shoulders 16 and 18 bulging from the outer wall 8. This ensures that the connector 50 is held in the recess. Both ends of the connector 50 extend continuously from the recess 2 and are mounted on the shelf 22 at a position higher than the bottom surface 20.

Next, FIGS. 4 and 5 show sectional views of the trays 1 and 1 '. FIG. 4 shows a cross section along line 4-4 in FIG.
The outer wall 8 is continuous with the recess 2 via the step 8a. Convex part 1
0 is lower than the outer wall 8 and has an upper surface 10a.
The upper surface 10a has substantially the same height as the step 8a. The protrusion 10 is continuous with the partition 4. Connector 50 is indicated by a dashed line in the figure. The bottom surface 52a of the housing 52 is separated from the bottom surface 20 of the concave portion 2, and the tine 56 is
, There is no possibility of deformation in the concave portion 2 due to collision. The upper surface 52b of the housing 52 has a protrusion 1
Note that the lower surface 10a is slightly lower.

Next, FIG. 5 shows the tray 5 'shown in FIG.
It is sectional drawing which follows a line. Referring to FIG. 5, the protrusion 10 '
Is not a cross section but its outer shape. Convex part 10 '
Is the same as the tray 1 except for the connector 50.
Is securely stored in the same manner as the tray 1 without the tine 56 coming into contact with other parts. 5, the upper surface 5 of the housing 50 is located at a position lower than the upper surface 10 'of the protrusion 10'.
Note that there is 2b '. 4 and 5 indicates a boss protruding from the bottom surface 52a of the housing 52.

Next, FIG. 6 shows a sectional view in which the trays 1 and 1 'are stacked. The cross-sectional position is the same position as the cross-section in FIGS. 4 and 5, and is a cross-sectional view along line 6-6 in FIG. Tray 1, tray 1 ′, and tray 1 are stacked in that order from the bottom, and each recess 2, 2 ′, 2 has a connector 50.
Is stored. The protrusions 10 when stacked here
The positional relationship between and and 10 'is shown in FIG. 3, and will be described below with reference to FIG. When the tray 1 ′ is placed on the lowermost tray 1, the outer walls 8, 8 ′ overlap and the flat bottom wall 28 ′ of the tray 1 ′ is placed in contact with the upper surface 10 a of the projection 10. At this time, the lower surface 28a 'of the bottom wall 28'
Are not in contact with the upper surface 52b of the housing 52. That is, the state where no load is applied to the housing 52b is maintained.

Next, when the tray 1 is further placed on the tray 1 ', the outer walls 8' and 8 overlap each other, and the bottom wall 28 of the tray 1 comes into contact with the upper surface 10a 'of the projection 10' of the tray 1 '. Is placed. Referring to FIG. 3, this is formed by displacing the projections 10 of the tray 1 indicated as A and the projections 10 'of the tray 1' indicated as B at the projections 12 and 12 '. It depends. That is, the protrusions 10, 1
Since the portions other than 0 'become flat bottom walls 28 and 28',
This is because this portion comes into contact with the other convex portions 10 'and 10.

Although the preferred embodiments of the present invention have been described in detail, it goes without saying that various modifications and alterations are possible within the scope of the present invention. For example,
The material is not limited to polystyrene, but may be any other suitable synthetic resin material.

[0021]

The article storage tray of the present invention has the following effects because two types of trays are prepared and the projections having a flat surface which is bulkier than the articles are provided at different positions.

That is, even if the trays are stacked, no load is directly applied to the articles, so that there is no consideration to damage or deform the articles. Many more stacks are possible. Especially when used for electrical components such as connectors, the deformation of the tines is prevented,
Since the alignment of tines at the time of solder connection is ensured, the possibility of defective products is significantly reduced, and the yield is good, so that there are great effects on product quality and production.
