Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing electronic component series in which a series of electronic components in which lead terminal portions of radial lead type electronic components are held by a tape are folded and folded.

[0002]

2. Description of the Related Art In recent years, automatic insertion of electronic parts has progressed, and along with this, when shipping small electronic parts such as radial lead type capacitors and inductors to customers, electronic parts arranged in a line A series of electronic component containers in which the lead terminals are held from both sides with a tape consisting of a mounting tape and a sticking tape, and this is folded in a zigzag form (so-called zigzag fold) to make an electronic component storage container made of paper or plastic such as corrugated paper. The method of storing in a (also called a packaging box) and transporting is generally adopted.

At this time, the taping of the above-mentioned radial lead type electronic parts is generally performed by the electronic part series 8 shown in FIG.
As shown in the plan view of FIG. 1, electronic components 1 are arranged at equal intervals.
The (radial) lead terminals 2 and 3 of a to 1e form a series of long-sized electronic component series 8 which is adhered and held between the mount tape 4 and the sticking tape 5, and the sticking and holding are performed. At the center of the tape between the formed electronic components, a feed hole 6 is formed for the automatic insertion device to convey the electronic component string 8.

As described above, the electronic component train 8 is housed in a zigzag manner by alternately folding back in a zigzag direction in the opposite direction by the length of the storage space of the electronic component train storage container 9, and the zigzag folding is usually performed. There are 25 or 20 electronic components in a row (between folds), and the packing unit (total quantity) is in principle a good quantity of 1000 or 500, so the electronic component series is It fits tightly without excess or deficiency.

In the meantime, in the electronic parts storage container 9, in order to prevent messy storage and to be folded back at a predetermined length, as shown in FIG. The fold line 7 is included in advance,
In addition, the folds 7 are designed to prevent the occurrence of bending of lead terminals due to the thickness of the electronic components 1a ... As shown in the front view of the state, the upper and lower electronic components are provided so as to be accommodated in the recessed positions between the electronic components in the rows adjacent to each other when the electronic component train 8 is accommodated.

That is, adjacent electronic components c, d, e in the same row
The folds 7 of the tape are provided so that the rows a, b and f, g in the upper and lower rows are inserted between the respective folds.

However, the above-mentioned storing method is effective if the electronic components to be stored are small and relatively thin. However, when the outer diameter of the electronic components to be taped is about 10 mm or more, the folding line 7 of the storing method is also used. The electronic parts folded in the vicinity are pressed against each other in a narrow space, and also hit the side wall 11 of the electronic parts storage container 9, so that bending of the lead terminals is likely to occur.

Therefore, conventionally, taping in a state (so-called tooth loss state) in which one part of the fold end 10 of the tape (the electronic part 1c of FIG. 5A) in which the lead terminal is most likely to be bent is removed is conventionally used. By adopting this, it was taken as a measure to prevent lead terminal bending.

[0009]

However, as described above, the conventional electronic component storage container 9 is originally made so that the zigzag fold is usually 25 or 20 in a line (one fold). In addition, the pitch between the parts of the tape, which consists of the mount tape and the adhesive tape, also has folds.

Therefore, the packing unit (total quantity) is 100
Even if the number of divisions is 0 or 500, the number of taped electronic component strips with one component of the fold end 10 removed is 24 or 19 in a row, which causes a fraction. Become.

As a result, the final row of the electronic component series ends halfway, and when the electronic component series 8 of FIG. 5A is stored in the conventional electronic component series storage container 9, the electronic component series is described above. Despite the idea of folding back the taping as described above, the front row that touches the end part of the last row of the electronic parts series and both sides of the parts due to the shock that swings in the electronic parts series storage container during transportation. Had a problem in that the lead terminals of the parts were bent.

In addition, since the electronic parts storage container is generally handled without distinction between upper and lower parts once it is stored and packed, it is often opened from the bottom side opposite to the packing. At this time, the component at the final end of the series of electronic components is subject to the pressure of the self-weight of the series of electronic components, and lead bending is likely to occur.

The above-mentioned situation will be described with reference to the partially enlarged front view of the electronic component series in the electronic component series storage container shown in FIG. 6, because the electronic component a at the end of the final row 12 of the electronic component series has no component on the left side. , The upper part of the row 13 before the final turn-back is pressed and bent in the direction of the arrow by the pressure from the electronic parts b and c which are in contact with each other, and the parts b and c are easily interrupted, and conversely, the part b which contacts the electronic part c , C can be said to have a high possibility of bending the lead terminals in the direction of the arrow.

The present invention has been made in view of the above circumstances, and in an electronic component storage container in which a taped electronic component storage is stored, after the end portion of the electronic component storage is folded back due to a shock during transportation or the like. An object of the present invention is to provide a container for accommodating a series of electronic components for the purpose of preventing bending of the lead terminals of the electronic components having a fractional end and the electronic components in the vicinity thereof.

[0015]

SUMMARY OF THE INVENTION (1) An electronic component string for accommodating a radial lead type electronic component string that is zigzag taped so that the electronic component bodies in the rows before and after each turn of the zigzag fold contact each other. In the storage container, there is provided an electronic component storage container, characterized in that partition means for preventing mutual contact is provided between a part of the end of the series of electronic parts after folding and a part before folding. By doing so, (2) the partitioning means is extended from the electronic component series accommodating container body toward the folded-back portion at the end of the electronic component series. By providing a container for accommodating electronic parts, (3) the partitioning means has a positioning means corresponding to an alignment pitch of the electronic parts in the series of electronic parts. (4) The length of the partitioning means is formed shorter than a predetermined length of the zigzag fold by providing the electronic component storage container according to (1). The above object is achieved by providing the electronic component storage container described above.

[0016]

In the electronic component storage container according to the present invention, (1) partitioning means for preventing mutual contact is provided between the end portion of the end portion of the electronic component connection after folding back and the portion before folding back. Since the partition means cuts off the displacement pressure caused by the contact between parts of the fractional part after folding and the part before folding, the electronic part of the fractional part after folding is cut between the electronic parts before folding. Play a role in preventing

Therefore, the vertical and horizontal displacement of the electronic component does not occur, so that the problem of bending the lead terminals can be prevented.

(2) Further, since the partition means is extended from the main body of the electronic parts storage container toward the folded-back portion at the end of the electronic parts series, the partition means is used as a partition piece to store the electronic parts in series. An electronic component that can be integrally die-cut with the same material as the container (for example, corrugated cardboard), and is folded like a door with one side that is continuous with the main body of the partition piece as the partitioning means being a fulcrum when taking out the electronic component series. As it opens following the pulling of the ream, it does not interfere with the automatic insertion and the removal is smooth.

(3) Further, since the partitioning means of (1) has the positioning means corresponding to the alignment pitch of the electronic parts in the series of electronic parts, the positional relationship between the upper and lower electronic parts is stably maintained individually. To do.

(4) Further, the electronic component continuous storage container in which the length of the partitioning piece which is the partitioning means of the above (1) is formed shorter than a predetermined length of the zigzag folding is the takeout described in the above (2). The smoothness at the time of will increase more.

That is, if the length of the partition piece is the same as the predetermined length of the zigzag fold, the straight shape of the partition piece pushes the fold line of the zigzag shape at the time of taking out the series of electronic parts, resulting in lack of smoothness. However, if the length of the dot partition piece is shorter than the predetermined length of the zigzag fold, the above-mentioned problem is solved. Even in this case, if the partition piece is sandwiched between at least the two end portions of the end portion of the electronic component series after folding back and the portion before the folding back, the electronic parts most likely to bend the lead. Electronic components near the component connecting end are protected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a storage container for electronic parts according to the present invention will be described in detail below with reference to the drawings. In addition, the same shape as the conventional
The same reference numerals will be used for functional members.

FIG. 1 is a perspective view showing a state in which an electronic component string 8 according to claim 1 of the present invention is folded and accommodated in an electronic component string 8 having the above-mentioned cylindrical component taping.

In FIG. 1, the electronic component storage container 20 is
A so-called packing box made of corrugated cardboard paper for storing a radial lead type electronic component string 8 that is zigzag-taped so that the electronic component bodies in the rows before and after each folding of the zigzag are in contact with each other. Between the part 14 after folding back of the part and the part 15 before folding back,
A partitioning piece 16 is provided as a partitioning means for preventing mutual contact.

The partition piece 16 as the partition means may be integrally connected to the main body of the electronic component storage container 20 or may be separate from the main body.

FIG. 2 is a partial cross-sectional view showing a storage state of the electronic component storage container in the electronic component storage container. FIG. 2A is a partition as a partition means integrally formed with the inner surface of the electronic component storage container. The piece 16a is a piece 16b, which is a partition piece 16b as a partitioning means that is configured separately from the electronic component storage container body.

The shape, size and material of the partitioning piece 16 as the partitioning means are not limited, and the fractional portion 14 after folding back of the end portion of the electronic component series 8 and the portion 1 before folding back.
Any material may be used as long as it can be fitted between the members 5 and 5 to prevent mutual contact. For example, it may be a corrugated partition piece 16c as shown in FIG.

With the above construction, it is apparent that the displacement pressure applied to the fractional part and the electronic components in the vicinity thereof is blocked by the partitioning piece 16 and the bending of the lead terminal is prevented.

It should be noted that the electronic component continuous storage container is generally made of paper such as corrugated cardboard or cardboard, and it is considered that the partition means is also made of paper of the same material, but the present invention is not limited to this. Of course, it may be made of synthetic resin such as resin.

Next, referring to FIG. 1, in an electronic component storage container 21 according to a second aspect of the present invention, the partition means extends from the electronic component storage container body toward the folded-back portion 17 at the end of the electronic component storage. It is characterized by being extended.

That is, the partition piece 1 as partition means.
6 is made of the same material (made of corrugated paper) as the main body of the electronic parts storage container, and extends from the corner edge 19 of the folded side surface part 18 in the main body as shown in the development view of the electronic parts storage container of FIG. It is die-cut from a piece of corrugated paper together with the main body. At this time, in order to clarify the correspondence of each part with the perspective view of FIG. 1, signs A to G are added to both parts.

In order to prevent bending of the lead terminals due to vibration of the electronic component storage container 21 during transportation, the paper piece 31 in the figure is a tape fold of the zigzag folded electronic component storage 8 and the side surface of the electronic component storage container. It is a cushioning material that fills the gap (see Japanese Patent Application No. 5-73682).

The length X of the partition piece 16 as the extended partition means is not limited, but at least between the end portion 14 after folding back and the portion 15 before folding back of the end portion of the electronic component series. Must be inserted.

Therefore, the required length X is set in advance by calculating the number of the fractional parts 15 after folding back of the continuous end portion of the electronic component from the predetermined total number of stored electronic components and the number in one row.

It is also possible to extend the length X of the partition piece 16 to a length longer than a predetermined length of the zigzag shape, and appropriately bend it when storing the parts. In this case, there is a difference in that the vacant gap from the fractional portion 14 after folding back of the electronic component connecting portion can be filled with the bent partitioning piece 16, and the taping pitch and the total number of stored electronic components are different. However, it also has the advantage of versatility.

Next, the electronic component storage container 22 according to claim 3 of the present invention has the positioning means for the partition paper piece 16 as the above-mentioned partitioning means, which corresponds to the alignment pitch of the electronic components in the electronic component series 8. This is characterized by, for example, a corrugated partitioning piece 16c that matches the wavelength of one pitch of the taped electronic component as shown in FIG. 2C.

The electronic components in the rows before and after the folding of the connecting end of the electronic component in contact with the partition 16c are held in the concave and convex portions of the partition 16c in a stable position.

Therefore, it is obvious that the electronic component storage container 22 having the partition 16c contributes to stabilizing the position of the electronic component more than a mere flat partition with respect to rolling during transportation. The positioning means is not limited to the corrugated shape but may be an uneven shape, and if the repeating pitch is not an interval of 1 pitch but an integer pitch of 2 pitches or 3 pitches, the same position stabilizing effect can be obtained. Of course.

Next, as shown in the sectional view showing the storage state of the electronic component storage container 23 according to claim 4 of the present invention in the electronic component storage container of FIG. 4, the partition paper piece 16 as the above-mentioned partitioning means. Is formed so as to be shorter than a predetermined length of the zigzag folding, and of course, the length X of the partition piece 16d as the partitioning means is at least after the folding of the end portion of the series of electronic components. A part between the fractional part 14 and the part 15 before folding back (1 to 3 at the end)
Must be fitted and inserted into a) to c) in the figure.

Even in this case, it is possible to prevent the bending of the lead terminals of the electronic component a at the end of the electronic components most susceptible to the shock during transportation and the electronic components b, c, e, f, g in the vicinity thereof. Obviously you can.

Further, when the straight-shaped partitioning piece 16 reaches the predetermined length of the zigzag when the electronic component string 8 is taken out, the folds are stretched and the smoothness of the taking out is impaired. However, the above-mentioned problem is solved in the electronic component continuous storage container 23 in which the length X of the point partitioning piece 16d is short.

It should be noted that the partition piece 16 as the partitioning means described above is made of corrugated cardboard, but the partitioning means may be made of another material. For example, it seems that even a product made of a synthetic resin such as styrofoam or a sponge having an appropriate hardness gives good results.

[0043]

Since the container for accommodating electronic parts according to the present invention is constructed as described above, it is held in a stable state in the container and the end portion of the container for electronic parts is caused by a shock during transportation. It has an excellent effect of preventing bending of the lead terminals of the fractional-end electronic component after folding back and the electronic components in the vicinity thereof.
