BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component package, and is particularly suitable for use as a tape-shaped container used for carrying electronic components such as ICs.

[0003]

2. Description of the Related Art Conventionally, a tape-shaped container of this type is known as shown in FIG. This tape-shaped container 1
Is made of a flexible resin material, and is composed of two portions, a concave portion 2 (hereinafter, referred to as an embossed portion 2) and a flange portion 3. Here, the embossed portions 2 are arranged at equal intervals along the longitudinal direction of the tape-shaped container 1, and are used to house one electronic component at a time. Further, the flange portion 3 is used to connect with a tape-shaped lid (not shown) so that the stored electronic components are not separated from the opening during transportation, and the feed holes 3A are equally spaced on both sides in the longitudinal direction. Many are arranged in.

[0004]

By the way, the tape-shaped container 1 during the transportation of the electronic component is wound around the reel 4 in multiple layers as shown in FIG. FIG. 12 shows the positional relationship between the embossed portions at each position on the circumference of the tape-shaped container 1 wound around the reel 4 in this way.
As shown in FIGS. 12A to 12C, the adjacent embossed portions 2 in the radial direction do not necessarily have a positional relationship in which the embossed portions 2 on the inner peripheral side are displaced in the radial direction, and in many cases, Deviated in the circumferential direction. In some cases, as shown in FIG. 13, the opening edge portion 2A of the embossed portion 2 on the inner peripheral side is located at the center of the bottom edge portion of the embossed portion 2 on the outer peripheral side.

The reel 4 may be subjected to various unexpected external forces such as a shock caused by a drop during conveyance, and a force for compressing the embossed portion 2 in the depth direction is applied in the radial direction of the reel 4. There is. At this time, the position of the opening edge of the embossed portion 2 on the inner peripheral side and the embossed portion 2 on the outer peripheral side
If the positions of the edge portions of the bottom surface are substantially coincident with each other, the embossed portions 2 are hardly deformed because the portions have relatively high strength. However, as shown in FIG. 13, when the opening edge portion 2A of the embossed portion 2 on the inner peripheral side is located at the center of the bottom edge portion of the embossed portion 2 on the outer peripheral side, the embossed portion 2 on the outer peripheral side is formed.
Since the strength of the bottom edge portion of the base plate in the radial direction is small, it may not be fully supported and may be deformed as shown in FIG. In the case of an electronic component, such deformation may lead to deformation or damage of the lead, which is not preferable.

The present invention has been made in consideration of the above points, and proposes a component package having an increased strength against the external force in the radial direction which acts on the tape-shaped container wound around the reel and conveyed. Is what you are trying to do.

[0007]

In order to solve such a problem, according to the present invention, recesses (2) for storing parts arranged at regular intervals in the longitudinal direction of a flexible tape-like object.

Further, in the present invention, among the side walls forming the recess (2), the third and fourth side walls adjacent to the first and second side walls are provided with a second continuous line along the opening edge. The folded pattern (12) is formed.
Further, according to the present invention, a concave-convex pattern (22) continuous in the longitudinal direction is formed in the central portion of the bottom surface forming the concave portion (2) excluding the peripheral region.

Further, according to the present invention, the concavo-convex pattern (72) continuous in the direction orthogonal to the longitudinal direction is formed in the central portion of the bottom surface forming the concave portion (2) excluding the peripheral region. Furthermore, according to the present invention, the central portion (3) of the bottom surface forming the concave portion (2) excluding the peripheral region.
2) projects more than the peripheral region (33). Further, in the present invention, the peripheral region (33) is formed with a continuous folded pattern (42) over the entire circumference.

[0010]

In the side walls forming the recesses (2) for accommodating parts, which are arranged at regular intervals in the longitudinal direction of the flexible tape-like object, openings are formed in the first and second side walls located on both sides in the longitudinal direction. By forming the continuous first folded pattern (12) along the edge, the strength of the recess (2) can be increased. This makes it difficult for the recess (2) to be deformed regardless of the external force in the depth direction, and it is possible to prevent deformation of the components housed in the recess (2).

The first of the side walls forming the recess (2)
And the third and fourth side walls adjacent to the second side wall also have a second folded pattern (1) that is continuous along the opening edge.
By forming 2), the strength of the recess (2) can be further increased. Further, by forming concavo-convex patterns (22) and (72) continuous in the longitudinal direction or in the direction orthogonal to the central part (32) of the bottom surface forming the recess (2) except for the peripheral region (33), The strength of the bottom surface can also be increased.

The central portion (32) of the bottom surface forming the recess (2) excluding the peripheral region (33) is the peripheral region (3).
Since the protrusion is made as compared with 3), the external force acting in the depth direction is first applied to the central portion protruding from the surroundings. This makes it possible to protect the fragile parts around the periphery. Further, by forming the folded pattern (42) continuous over the entire circumference in the peripheral area (33) of the bottom surface, the strength of the peripheral area (33) of the bottom surface can be increased. As a result, it is possible to obtain a package having an excellent protection function for the stored components.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

(1) First Embodiment In FIG. 1 in which parts corresponding to those in FIG. 10 are designated by the same reference numerals, reference numeral 11 indicates a tape-shaped container used as a whole to house a QFP / IC. There is. In this tape-shaped container 11, the concavo-convex pattern 12 is formed with narrow pitches over the entire side wall of the embossed portion 2, and the electronic component main body 13 is positioned by being inserted between the lead and the main body. The guard rib 14 and the step portion 15 for lifting the electronic component body 13 are provided on the bottom surface of the embossed portion 2. The step portion 15 separates the tip of the lead from the bottom surface and side wall of the embossed portion 2, so that the lead can be prevented from being deformed or damaged even if the bottom surface is slightly deformed.

A case will be described in which the tape-shaped container 11 having the electronic components housed in the embossed portion 2 is wound around the reel 4 and conveyed, as shown in FIG. Also in the case of the tape-shaped container 11 used in this embodiment, there is a winding misalignment portion as shown in FIG. In the case of the conventional tape-shaped container 1, when the inner peripheral side embossed portion 2 and the outer peripheral side embossed portion 2 have such a positional relationship, the side wall portion may not be able to support the external force and may be deformed. However, in the case of the tape-shaped container 11 used in this embodiment, since the concave / convex pattern 12 is formed with narrow pitches over the entire circumference to increase the strength, deformation is prevented regardless of the external force in the radial direction. be able to. According to the above configuration, it is possible to prevent deformation of the lead located inside the side wall of the embossed portion 2, and to realize a tape-shaped container with high protection performance for electronic components.

(2) Second Embodiment In FIG. 2 in which parts corresponding to those in FIG. 1 are designated by the same reference numerals, a plurality of ribs 22 extending in the longitudinal direction are formed on the bottom surface of the tape-shaped container 21. It has the same configuration except that The upper surface of the convex portion of the rib 22 is formed to have the same height as the height of the stepped portion 12D described in the preceding paragraph, so that the bottom surface of the electronic component body 13 can be entirely supported. Thereby, even when an external force acts on the bottom surface, the force can be evenly distributed over the entire surface of the electronic component body 13.

Further, since the plurality of ribs 22 are formed on the bottom surface as described above, the strength in the radial direction can be increased as compared with the case where the ribs 22 are not provided, and the deformation of the embossed portion 2 is prevented. It is designed so that you can do it. This can further enhance the function of protecting the electronic components housed inside the embossed portion 2 from external force. According to the above configuration, it is possible to realize a tape-shaped container having a high protection performance for electronic components, which can prevent deformation of the lead located inside the side wall of the embossed portion 2 and can effectively prevent deformation of the bottom portion. be able to.

(3) Third Embodiment A tape-shaped container 31 will be described with reference to FIG. 3 in which parts corresponding to those in FIG. By the way, FIG. 3 (A) is shown in FIG.
It is a view seen from the bottom surface side of the tape-shaped container 31, unlike FIG. 1, and the height of the bottom surface region 32 of the portion facing the electronic component body 13 is higher than the height of the bottom surface region 33 of the portion facing the lead. It has the same configuration except that it is deep when the opening edge is used as a reference.

Since the bottom surface region 32 projects toward the bottom surface region 33 in this way, even when an external force is applied in the radial direction while being wound on the reel 4, the external force is applied to the bottom surface region. 32 can be acted on first. That is, an external force is not applied to the bottom surface area 33 facing the lead. As a result, even if the reel 4 is accidentally dropped during conveyance, the external force is evenly applied to the electronic component main body 13 having high physical strength, and most external force is applied to the lead that is highly likely to be damaged. You can turn it off.

In addition, since the outer wall located on the outer periphery of the lead has a strong structure by the concavo-convex pattern 12B, the electronic components housed inside the embossed portion 2 can be reliably protected from external force. According to the above configuration,
The side wall and the bottom surface of the embossed portion 2 are structured to be resistant to deformation by the uneven pattern 12B and the ribs 22C, and the height of the area of the bottom surface facing the electronic component body 13 to be protected is a physically weak lead. By projecting the tape-shaped accommodating body with respect to the height of the facing area, it is possible to reliably prevent the deformation of the leads even when an external force acting in the radial direction of the reel 4 is provided, and thus a tape-shaped accommodating body having a high protection performance for electronic components. Can be realized.

(4) Fourth Embodiment In FIG. 4 in which parts corresponding to those in FIG.
The tape-shaped container 41 will be described. This tape-shaped container 4

The cross-sectional structure of this rib 42 is shown in FIG.

By providing the ribs 42 having narrow pitches extending radially in the relatively narrow bottom portion facing the lead region 33, the rigidity of this region can be further enhanced. That is, the space between the side wall of the embossed portion 2 and the guard rib 12 can be prevented from being compressed.
The ribs 42 are strong against the external force (compression / expansion) in the longitudinal direction of the tape-shaped container 41, and the external force (compression / expansion) from both sides of the tape-shaped container 41 causes a space between the guard rib 42 and the side wall of the embossed portion 2. It is possible to obtain a tape-shaped container in which the space can be kept constant.

(5) Other Embodiments In the first embodiment described above, the case where the concavo-convex pattern 12B of the same pitch is provided on the entire circumference of the side wall of the embossed portion 2 has been described, but the present invention is not limited to this. Alternatively, as shown in FIG. 6, it can be applied to the case where the concavo-convex pattern 12 is provided only on both sides in the longitudinal direction. Further, as shown in FIG. 7, the pitch of the concave / convex pattern 12 formed on the side wall located in the longitudinal direction of the tape-shaped container and the pitch of the concave / convex pattern 12 formed on the side wall located between the adjacent embossed portions 2 are shown. It can also be applied when setting different values. In this way, whether or not to form the concave-convex pattern on the side wall portion facing the adjacent embossed portion 2 may be selected appropriately according to the size of the electronic component to be stored.

Further, at this time, as shown in FIG. 9, the concavo-convex pattern 12 formed on the side wall and the rib 22 formed on the bottom surface may be directly connected to each other so as to be connected in a U-shaped cross section. Even in this case, sufficient strength can be obtained.

Further, in the above-described third embodiment, the uneven pattern 12 is formed on the side wall and the rib 22 is formed on the bottom surface.
Although the embossed portion 2 formed with the above is described, the present invention is not limited to this, and is also applicable to a tape-shaped container in which the rib 22 is only formed in the bottom surface region of the portion facing the electronic component body 13. Applicable. In this case, the strength of the side wall that protects the periphery of the lead is lower than that of the embodiment, but the external force that acts in the radial direction of the reel 4 is applied to the bottom surface region 32 that protrudes as compared with the periphery, and the electronic component body 13 Since it is evenly distributed over the entire surface, the lead protection function is higher than in the past.

Further, in the above-described fourth embodiment, the case where the rib 42 formed in the bottom surface area facing the lead is formed as shown in FIG. 5 has been described, but the present invention is not limited to this, and the rib 42 is not limited to this.
