Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embossed tape for accommodating parts of electrical equipment.

BACKGROUND ART Conventionally, embossed tapes (embossed carrier tapes) have been used to accommodate parts of electrical equipment and the like. In addition, in this application, the parts etc. of the electrical equipment accommodated in an embossed tape may be called "an object to be accommodated." In general, embossed tape is formed with a plurality of pockets (embossed) that can accommodate objects to be stored. can be sealed. By using such an embossed tape, even small parts can be stored and transported safely and conveniently.

FIG. 16 is an external view of part of the embossed tape 101 according to the conventional example. 17 is a schematic view of the FF section of the embossed tape 101 shown in FIG. The embossed tape 101 has a plurality of pocket portions 112 arranged side by side on a sheet portion 111 elongated in the front-rear direction, and an object to be accommodated can be accommodated in each of the pocket portions 112 .

The embossed tape 101 is formed by subjecting a heated sheet material to press-drawing processing for providing depressions. In the sheet material, the recessed portion formed by the press drawing becomes the pocket portion 112 , and the remaining portion remains as the sheet portion 111 .

For the convenience of forming the pocket portion 112 by press drawing, as shown in FIG. 17, a corner portion 112c located at the boundary between the bottom surface 112a and the side surface 112b of the pocket portion 112 is rounded (R-shaped). be done. Further, as a conventional carrier tape, for example, the one disclosed in Patent Document 1 can be cited. This carrier tape is provided with a cushioning mechanism in a pocket formed in the embossed tape so as to absorb drop impact and the like.

The object accommodated in the embossed tape is taken out from the pocket portion using a suction nozzle or the like and used, for example, in the manufacturing process of an electric device. It is very important to ensure the quality of the manufacturing process and the like that the stored object can be easily taken out of the pocket.

In view of this point, if the contact area between the object to be accommodated in the pocket and the bottom surface or side surface of the pocket is large, the following problems are likely to occur. First, an object to be accommodated in the embossed tape may have oil or the like adhering to it. For example, when the object to be stored is a pre-plated metal press-formed product, press oil is often adhered to the object to be stored.

When such an object is accommodated in the pocket portion of the embossed tape and the object and the bottom surface or the side surface of the pocket portion are in close contact with each other over a wide range, the press oil does not dry out at that point and the press oil and the object are not dried. There is a risk that a reaction (chemical reaction, etc.) with the storage object will occur, and the solderability (ease of soldering) of the object to be housed will deteriorate. In addition, the press oil may not dry and the object to be stored may stick to the bottom surface or the side surface of the pocket, making it difficult to remove the object from the pocket.

Further, for example, in the case of the embossed tape 101 described above, the R-shaped portion of the corner portion 112c has a shape that gradually advances upward from the edge of the bottom surface 112a. Therefore, as shown in FIG. 18, the end portion of the object to be stored OB runs over the corner portion 112c, and the object to be stored OB is likely to tilt. If such a tilt occurs, when the object to be accommodated OB is taken out from the pocket portion 112 using a suction pad (vacuum pad), there is a risk that suction of the object to be accommodated OB to the suction pad will be hindered. Therefore, it may become difficult to take out the stored object from the pocket portion.

Furthermore, when an object to be stored having projections such as burrs formed thereon is stored in the pocket portion, there is a risk that the projections will catch on the pocket portion and tilt the object to be stored (see FIG. 24, etc.). In this case, too, it may become difficult to take out the stored object from the pocket portion.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an embossed tape that makes it easier to take out a stored object from a pocket portion. In other words, it is an object of the present invention to provide an embossed tape capable of facilitating the taking out of a stored object from a pocket portion by providing avoiding means for avoiding close contact with the outer surface of the stored object or oblique storage of the stored object. . More specifically, an embossed tape that makes it possible to prevent projections such as burrs formed on an object to be accommodated from being caught in the pocket, an object to be accommodated in the pocket and the bottom or side surface of the pocket An embossed tape that makes it easier to reduce the adhesion area between, or suppresses the inclination of the stored object due to riding on the R-shaped part formed at the boundary between the bottom surface and the side surface of the pocket part.

Embodiments of the present invention will be described below with reference to the respective drawings, taking first to fourth embodiments as examples.

1. First Embodiment First, a first embodiment will be described. In the following description, directions of up and down, left and right, and front and back (directions perpendicular to each other) are as shown in FIG. The front-back direction corresponds to the direction in which the embossed tape 1 extends, and the left-right direction corresponds to the width direction of the embossed tape 1 . Moreover, the upward direction coincides with the opening direction of the pocket portion 12, which will be described later.

FIG. 1 is a partial configuration diagram of an embossed tape (embossed carrier tape) 1 according to this embodiment. 2 is a cross-sectional view taken along line AA of the embossed tape 1 shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB of the embossed tape 1 shown in FIG. Also, FIG. 4 is a partial configuration diagram of the embossed tape 1 in a state in which an object to be accommodated OB (as an example, a small contact mounted on a portable communication device) is accommodated. It is assumed here that the object to be accommodated OB has an overall rectangular parallelepiped shape. The lower outer surface (lower surface) of the object to be accommodated OB is planar, and is parallel to the bottom surface 12 a of the pocket portion 12 when the object to be accommodated OB is accommodated in the pocket portion 12 .

As shown in the above figures, the embossed tape 1 has a sheet portion 11, a pocket portion 12, a left support projection 13a and a right support projection 13b. The embossed tape 1 has a sheet part 11 elongated in the front-rear direction and a plurality of pocket parts 12 arranged in the front-rear direction at regular intervals, and each pocket part 12 can accommodate an object OB.

The embossed tape 1 is formed by subjecting a heated sheet material to a press drawing process for providing depressions. The sheet material is made of a material such as plastic that softens when heated, and is made of PS (polystyrene), PET (polyethylene terephthalate), or PP (polypropylene), for example. In the sheet material, the recessed portion formed by the press drawing becomes the pocket portion 12 , and the remaining portion remains as the sheet portion 11 .

The sheet portion 11 is a sheet-like (tape-like) portion that extends long in the front-rear direction with the left and right sides as the width direction. A plurality of feed holes 11a used for such purposes are provided at regular intervals in the front-rear direction. A cover tape (not shown) can be adhered to the upper surface of the sheet portion 11 so as to seal each pocket portion 12 by, for example, heat sealing.

The pocket portion 12 is a pocket-shaped portion in which a space for storing an object to be stored is formed. It faces side 12b. The bottom surface 12a of the pocket portion 12 is parallel to the upper surface of the seat portion 11, and is formed to extend forward, backward, leftward, and rightward. The angle between the bottom surface 12a and the front, rear, left, and right side surfaces 12b is 90 degrees or slightly larger.

The pocket portion 12 has an opening at the top, and an object OB to be accommodated can be accommodated and taken out through this opening. The spatial shape of the pocket portion 12 is a substantially rectangular parallelepiped shape with the front and rear as the short direction and the left and right as the longitudinal direction. Further, the space size of the pocket portion 12 is set slightly larger than the object to be accommodated OB so that the object to be accommodated OB can be easily accommodated and taken out. The distance between the left and right side surfaces 12b is approximately 3 to 4 mm, and the distance between the front and rear side surfaces 12b is approximately 1 to 2 mm.

For the convenience of forming the pocket portion 12 by press drawing, as shown in FIGS. A shape (roundness) is formed. The radius of curvature of the R shape is about 0.1 mm. The vertical position β of the upper end of this R-shaped portion is as shown in FIGS. The rounded shape of the corner portion 12c gradually progresses upward from the edge of the bottom surface 12a to the position β in the vertical direction. At a location above the vertical position β, no R shape is formed, and the inclination of the surface of the pocket portion 12 is constant.

The left support projection 13a and the right support projection 13b are formed at the same time as the pocket portion 12 by the above-described press drawing, and are provided to protrude upward from the bottom surface 12a of the pocket portion 12. As shown in FIG. The tips (upper ends) of these support projections 13a and 13b support upward the storage object OB stored in the pocket portion 12. As shown in FIG. In addition, the support protrusions 13a and 13b are arranged symmetrically with respect to a plane that bisects the pocket portion 12 into right and left halves, so that the object to be accommodated OB can be supported in a well-balanced manner.

By storing and packaging the object OB in the embossed tape 1, it is possible to store and transport the object OB safely and conveniently. In this storage/packaging step, for example, the embossed tape 1 wound around a reel is fed out in order from the end, and the storage object OB is stored in the pocket portion 12 . After that, a cover tape is fixed to the surface of the sheet portion 11 to seal the stored object in the pocket portion 12 .

When using the object OB stored and packaged in the embossed tape 1, the cover tape fixed to the embossed tape 1 is removed from the surface of the sheet portion 11 to expose the object OB. should be taken out. This extraction can be realized, for example, by causing a suction pad (vacuum pad) to absorb the top surface of the object to be accommodated OB and moving the suction pad as it is.

Next, the shape and characteristics of each support protrusion 13a, 13b will be described in more detail.

The left support projection 13a is provided at a position on the left side of the bottom surface 12 so that both ends thereof extend in the front-rear direction to the vicinity of the front and rear side walls 12b of the pocket portion 12. As shown in FIG. On the other hand, the right support projection 13b is provided at a position on the right side of the bottom surface 12 so that both ends thereof extend in the front-rear direction to the vicinity of the front and rear side walls 12b of the pocket portion 12. As shown in FIG. The surfaces of the support projections 13a and 13b have substantially the same shape as part of the surface of the cylinder extending forward and backward.

Therefore, as shown in FIG. 2, in a cross section cut along a plane whose normal direction is the front-rear direction, the upper surfaces of the support projections 13a and 13b are arcs exposed upward (one form of curved lines convex upward). has the shape of Further, as shown in FIG. 3, in a cross section taken along a plane whose normal direction is the left-right direction, the surfaces of the support projections 13a and 13b are straight lines extending forward and backward. It can be said that the tip portions of the support projections 13a and 13b are both convex curved surfaces.

As shown in FIGS. 5 to 7, the support projections 13a and 13b are in line contact with the lower outer surface of the object OB (a plane whose normal direction is the vertical direction). It is considered to be a shape. 5 is a cross-sectional view of the embossed tape 1 shown in FIG. 4 taken along line C--C, and FIG. 6 is a cross-sectional view taken along line D--D of the embossed tape 1 shown in FIG. 7 is an enlarged view of the region P indicated by the dotted line frame in FIG. 5. As shown in FIG.

As shown in these figures, the left support projection 13a is in line contact with the corresponding outer surface of the object OB at a line segment La extending in the front-rear direction, and the right support projection 13b is in line contact with the corresponding outer surface of the object OB at a line segment Lb extending in the front-rear direction. It is in line contact with the corresponding outer surface of the object to be accommodated OB. An object OB housed in the pocket portion 12 is supported upward only by line contact with the support projections 13a and 13b, and does not come into contact with the bottom surface 12a. The support projections 13a and 13b are arranged in the pocket portion 12 in a well-balanced manner, and can stably support the object to be accommodated OB. Assuming that the tips of the support projections 13a and 13b are not deformed, they are in almost perfect line contact with the object to be accommodated OB, but in reality they are slightly deformed by the load received from the object to be accommodated. Therefore, line contact in the strict sense may not be maintained. "Line contact" in the present application is a concept including such a situation.

Since the tips of the support projections 13a and 13b are in line contact with the corresponding outer surface of the object to be stored OB, the object to be stored in the pocket portion 12 and the bottom side of the pocket portion 12 are in close contact with each other. It is possible to make the area as small as possible. Therefore, even if the press oil adheres to the object to be accommodated OB, the press oil is likely to dry between the object to be accommodated OB and the bottom surface of the pocket portion 12 . As a result, chemical reaction or the like between the object to be accommodated OB and the press oil can be suppressed, and deterioration of the solderability (ease of soldering) of the object to be accommodated OB can be prevented as much as possible. Furthermore, it is possible to prevent the object OB from sticking to the bottom surface of the pocket portion 12 without drying the press oil and making it difficult to take out the object OB from the pocket portion 12 as much as possible.

Further, as shown in FIGS. 2 and 3, the vertical position α of the tip of each support projection 13a, 13b is above the vertical position β of the upper end of the R-shaped portion formed at the corner 12c. there is In this embodiment, the distance between the bottom surface 12a and the position α is approximately 0.2 mm, and the distance between the bottom surface 12a and the position β is approximately 0.1 mm. Thereby, as shown in FIGS. 5 and 6, the lower surface of the object OB accommodated in the pocket portion 12 is located above the R-shaped portion.

Therefore, as illustrated in FIG. 18, it is possible to prevent the end of the object to be stored OB from running over the corner portion, and to prevent the object to be stored OB from tilting in the pocket portion 12 . . As a result, when the object to be accommodated OB is taken out from the pocket portion 12 using the suction pad (vacuum pad), the upper outer surface of the object to be accommodated OB is horizontal, and the object to be accommodated OB is sucked to the suction pad. can be performed more reliably. Even if the tips of the support projections provided on the bottom surface 12a do not come into line contact or point contact with the corresponding outer surface, the object of preventing the ends of the objects to be stored OB from running over the corners is achieved. can be

FIG. 8 is an external view of a contact OB1, which is a specific example of the object to be accommodated OB, and FIG. 9 is an external view of the contact OB1 viewed from another angle. The contact OB1 is formed by bending a sheet of metal plate, and includes a bottom portion OB11, a contact portion OB12 connected to the bottom portion OB11 via a leaf spring, and a housing portion OB13 that covers and protects the leaf spring. , have The contact portion OB12 is formed to be urged upward by a leaf spring when pushed downward by the object to be connected. Thereby, it is possible to stably and electrically connect the object to be connected soldered to the lower surface (flat) of the bottom portion OB11 to the object to be connected. When the contact OB1 is accommodated in the pocket portion 12, the points roughly indicated by broken lines in FIG. 9 are in line contact with the tips of the support protrusions 13a and 13b.

2. Second Embodiment Next, a second embodiment of the present invention will be described. The second embodiment is basically the same as the first embodiment, except for the form of the support projections. In the description of the second embodiment, emphasis will be placed on the description of portions different from the first embodiment, and descriptions of portions common to the first embodiment may be omitted.

FIG. 10 is an external perspective view of a portion (pocket portion 12) of the embossed tape 2 according to the second embodiment. Further, FIG. 11 is an external perspective view of a portion (pocket portion 12) of the embossed tape 10 in a state in which an object to be stored OB is stored.

As shown in FIG. 10, the embossed tape 2 of the second embodiment is provided with six support projections (13c to 13h) instead of the support projections 13a and 13b of the first embodiment. These support projections 13c to 13h are provided so as to protrude upward from the bottom surface 12a of the pocket portion 12. As shown in FIG. The tip (upper end) of each of the support projections 13c to 13h supports the corresponding outer surface of the object OB stored in the pocket portion 12 upward.

The first support projection 13c is provided on the left side of the bottom surface 12 and at the center in the front-rear direction. The second support projection 13d is provided on the right side of the bottom surface 12 and at the center in the front-rear direction. The third support protrusion 13e and the fifth support protrusion 13g are provided so as to line up in the front-rear direction at a position slightly to the left of the bottom surface 12 (to the right of the first support protrusion 13c). The fourth support projection 13f and the sixth support projection 13h are provided so as to line up in the front-rear direction at a position slightly to the right of the bottom surface 12 (to the left of the second support projection 13d). Also, the first support protrusion 13c and the second support protrusion 13d, the third support protrusion 13e and the fourth support protrusion 13f, and the fifth support protrusion 13g and the sixth support protrusion 13h are arranged in the same direction as the pocket portion 12 to the left and right. They are arranged symmetrically with respect to the dividing plane, and can support the object to be accommodated OB in a well-balanced manner.

The surface of each of the support projections 13c to 13h has substantially the same shape as part of the surface of the sphere. Therefore, the upper surface of each of the support projections 13c to 13h is an arc exposed upward (a It has a shape of a convex curve). It can be said that the tips of the support projections 13c to 13h all have a convex surface shape.

In this way, each of the support projections 13c to 13h has a shape in which the tip portion is in point contact with the corresponding outer surface (a plane whose normal direction is the vertical direction) on the lower side of the object to be accommodated OB. Here, FIG. 12 is an arrow view of the EE cross section of the embossed tape 2 shown in FIG. This figure shows how the first to fourth support projections 13c to 13f are in point contact with the object to be accommodated OB.

The first and second support projections 13c and 13d have a slightly larger radius of curvature in the surface shape and a slightly larger amount of protrusion from the bottom surface 12a than the third to sixth support projections 13e to 13h. ing. In this manner, the shape and dimensions of each of the support projections 13c to 13h are adjusted so that all of the support projections 13c to 13h are in point contact with the lower outer surface of the object to be accommodated OB.

Each of the support protrusions 13c to 13h makes point contact with the object to be accommodated OB at the tip (central portion when viewed from above). The object OB housed in the pocket portion 12 is supported upward only by point contact with the support projections 13c to 13h, and does not come into contact with the bottom surface 12a. The support projections 13c to 13h are arranged in a well-balanced manner inside the pocket portion 12, and can stably support the object to be accommodated OB. Assuming that the tips of the support projections 13c to 13h are not deformed, they are in almost complete point contact with the object to be accommodated OB, but in reality they are slightly deformed by the load received from the object to be accommodated. Therefore, point contact in the strict sense may not be maintained. "Point contact" in the present application is a concept including such a situation.

Since the tips of the support projections 13c to 13h are in point contact with the corresponding outer surface of the object to be stored OB, the object to be stored in the pocket portion 12 and the bottom side of the pocket portion 12 are in close contact with each other. It is possible to make the area as small as possible. Therefore, as in the case of the first embodiment, it is possible to prevent deterioration of the solderability of the object to be accommodated OB and a situation in which the object to be accommodated OB is difficult to take out from the pocket portion 12 as much as possible.

Also in the second embodiment, as in the first embodiment, the vertical position of the tip of each of the support projections 13c to 13h is higher than the vertical position of the upper end of the R-shaped portion formed in the corner portion 12c. is also on the top. Therefore, as illustrated in FIG. 18, it is possible to prevent the end of the object to be stored OB from running over the corner portion, and to prevent the object to be stored OB from tilting in the pocket portion 12 . .

3. 3rd Embodiment Next, 3rd Embodiment of this invention is described. It should be noted that the third embodiment is basically the same as the first embodiment, except for the support projections. In the description of the third embodiment, emphasis will be placed on the description of portions different from the first embodiment, and descriptions of portions common to the first embodiment may be omitted.

In addition, in this figure, an external view from a top view is shown, a cross-sectional view along the FF plane is shown on the right side, and a cross-sectional view along the GG plane is shown on the lower side.

As shown in FIG. 15, in the embossed tape 3 in the third embodiment, instead of the support projections 13a and 13b in the first embodiment, six side support projections 14a to 14f (support projections according to the present invention) are provided. one form) is provided. The first side support projection 14a is provided so as to protrude rightward from the left side surface 12b of the pocket portion 12 . The second side support projection 14b is provided to protrude leftward from the right side surface 12b of the pocket portion 12 . The third side support protrusion 14c and the fifth side support protrusion 14e are provided so as to protrude rearward from the front side surface 12b of the pocket portion 12 . The fourth side support protrusion 14d and the sixth side support protrusion 14f are provided so as to protrude forward from the rear side surface 12b of the pocket portion 12 .

The first side support projection 14a is provided at a position near the top of the left side surface 12b and in the center in the front-rear direction. The second side support projection 14b is provided on the right side surface 12b at a position near the top and in the center in the front-rear direction. The third side support projection 14c is provided at a position nearer to the upper side and rightward on the front side surface 12b. The fourth side support projection 14d is provided at a position on the rear side surface 12b nearer to the upper side and to the right. The fifth side support projection 14e is provided at a position on the front side surface 12b nearer to the upper side and to the left. The sixth side support projection 14f is provided at a position on the rear side surface 12b nearer to the upper side and to the left. The first side support protrusion 14a and the second side support protrusion 14b face each other in the left-right direction, the third side support protrusion 14c and the fourth side support protrusion 14d face each other in the front-rear direction, and the fifth side support protrusion 14e and 14 f of 6th side support protrusions are facing the front-back direction. When the object to be accommodated OB is arranged exactly in the center of the pocket portion 12, a slight gap is formed between the object to be accommodated OB and the side support projections 14a to 14f.

In this way, the side support projections 14a to 14f are arranged in a well-balanced manner on the front, rear, left, and right side surfaces 12 surrounding the space of the pocket portion 12, and can support the object OB to the front, rear, left, and right, and inward. is. As a result, the object to be accommodated OB does not come into contact with any of the front, rear, left, and right side surfaces 12b, and is maintained near the center of the space of the pocket portion 12 when viewed from above.

Further, like the support projections 13a and 13b of the first embodiment, the tips of the side support projections 14a to 14f are in line contact with the corresponding outer surface of the object to be accommodated OB (contact with a line extending vertically). , and supports the object to be accommodated OB in the protruding direction of the side support projections 14a to 14f. The tips of the side support projections 14a to 14f are all convexly curved like the support projections 13a and 13b of the first embodiment.

Since the tips of the side support projections 14a to 14f are in line contact with the corresponding outer surface of the object to be stored OB, the object to be stored in the pocket portion 12 and the entire side circumference of the pocket portion 12 are in contact with each other. It is possible to minimize the contact area between the layers. Therefore, even if the press oil adheres to the object to be accommodated OB, the press oil is easily dried between the object to be accommodated OB and the side surface of the pocket portion 12 . As a result, chemical reaction or the like between the object to be accommodated OB and press oil can be suppressed, and deterioration of the solderability of the object to be accommodated OB can be prevented as much as possible. Furthermore, it is possible to prevent the object OB from sticking to the side surface of the pocket portion 12 without drying the press oil and making it difficult to take out the object OB from the pocket portion 12 as much as possible.

Further, the tips of the side support projections 14a to 14f are located closer to the projecting direction than the R-shaped portion formed in the corner portion 12c. For example, when focusing on the third side support projection 14c in FIG. 15, the rear end of the R-shaped portion formed at the corner portion 12c corresponding to the front side surface 12b (the side surface 12b on which the side support projection 14c is provided) is positioned forward and backward. The front-rear direction position γ of the tip portion of the third side support projection 14c is behind the direction position δ. That is, the tip of the third side support projection 14c is positioned closer to the rear side (toward the projecting direction of the third side support projection 14c) than the R-shaped portion formed in the corner portion 12c.

Therefore, by suppressing the object to be accommodated OB from approaching the R-shaped portion, the ends of the object to be accommodated OB are prevented from running over the corners as illustrated in FIG. tilting in the pocket portion 12 can be prevented. As a result, when the object to be accommodated OB is taken out from the pocket portion 12 using the suction pad, the upper outer surface of the object to be accommodated OB is horizontal, so that the object to be accommodated OB can be more reliably sucked onto the suction pad. can be done. All or part of the tip end portions of the lateral support projections 14a to 14f may be formed so as to make point contact with the corresponding outer surface of the object to be accommodated OB. Also, even if the tip of the lateral support projection provided on the side surface 12b does not come into line contact or point contact with the corresponding outer surface, the end of the object to be accommodated OB does not run over the corner. can be achieved.

4. Fourth Embodiment Next, a fourth embodiment of the present invention will be described. The fourth embodiment is basically the same as the first embodiment, except that instead of supporting projections, recesses are provided to avoid contact with burrs (one form of projections). In the description of the fourth embodiment, emphasis will be placed on the description of portions different from the first embodiment, and descriptions of portions common to the first embodiment may be omitted.

The embossed tape 4 according to the fourth embodiment accommodates a contact (an object to be accommodated) OB2 having burrs at predetermined locations. 12 (see FIG. 26). First, the contact OB2 accommodated in the embossed tape 4 will be described.

FIG. 19 is an external perspective view of an intermediate product MP produced in the manufacturing process of the contact OB2, and FIG. 20 is an external view of the intermediate product MP from above. The intermediate product MP is formed by bending a sheet of metal plate material, and is in a state in which a plurality of main parts MP1, which later become contacts OB2, and carrier parts MP2 are connected. When the intermediate product MP is cut along lines L indicated by dashed lines in FIG. 20 in the above manufacturing process, it is separated into a plurality of main parts MP1 and carrier parts MP2, and each main part MP1 is obtained as a contact OB2.

The basic configuration and function of the contact OB2 are the same as those of the contact OB1 in the first embodiment. As shown in FIG. 23, the contact OB2 has a bottom portion OB21, a contact portion OB22 connected to the bottom portion OB21 via a leaf spring, and a housing portion OB23 that covers and protects the leaf spring. The contact portion OB22 is formed to be urged upward by a leaf spring when pushed downward by the object to be connected. Thereby, it is possible to stably and electrically connect the object to be connected soldered to the lower surface (flat) of the bottom portion OB21 to the object to be connected.

FIG. 21 schematically shows the process of cutting the intermediate product MP along the line L. As shown in FIG. As shown in this figure, in this process, the fixed blade C1 is set above the carrier portion MP2, and the movable blade C2 is set below the main portion MP1. disconnected. The upper surface of the carrier portion MP2 with which the fixed blade C1 contacts and the lower surface of the main portion MP1 with which the movable blade C2 contacts form substantially the same plane except for a deviation corresponding to the thickness of the metal plate. Cleavage with (C1, C2) is easy. Incidentally, if such a blade were to be set above the main portion MP1, the contact portion OB22 or the housing portion OB23 might come into contact with this blade and be deformed or damaged. Therefore, in order to avoid such a problem, it is necessary to set the blade below the main portion MP1 as in the present embodiment.

However, when the intermediate product MP is cut in the form shown in FIG. 21, a burr (carrier cut burr) protruding generally downward at the cut location, that is, the location indicated by α in the drawing (the left end of the bottom portion 21). ) occurs. FIG. 22 shows a photograph of burrs BR generated in this manner. If the contact OB2 with the burr BR is housed in a pocket of a general embossed tape, the burr BR may get caught in the pocket and the contact OB2 may not be housed in the embossed tape at a correct position.

FIG. 23 shows how the contact OB2 is housed in a pocket of a typical embossed tape 400 at a correct position, and FIG. 24 shows that the burr BR of the contact OB2 is caught on the bottom of the pocket and the contact OB2 is tilted. It shows how it was stowed in a state (in an incorrect position). 23 and 24 (as well as FIGS. 25 to 27 described later) are views from the same viewpoint as FIG. In both FIGS. 23 and 24, the contact OB2 is housed in the pocket and then sealed using the cover tape CT. However, in the state shown in FIG. 24, the contact OB2 is placed at a slightly rightward position in the pocket portion, and is tilted by abutting the right end portion against the right side surface of the pocket portion. Even in this state, if the lower portion of the contact OB2 slides on the bottom surface of the pocket portion, the inclination will be eliminated. However, the contact OB2 remains tilted. In particular, the burrs generated by the cutting process as described above often have sharper tips than the protrusions that are intentionally provided as part of the product, and as described above, they bite into the bottom surface (the surface of the pocket). Easy to store.

If the contact OB2 is tilted in this way, there arises a problem that the contact OB2 cannot be properly sucked by a suction nozzle (a nozzle for vacuum-sucking a component or the like to its tip and conveying it). FIG. 25 schematically shows how the problem occurs when the upper surface of the housing portion OB23 of the contact OB2 is to be sucked by the suction nozzle. If the contact OB2 is tilted as shown in this figure, a gap is generated between the end surface of the suction nozzle C3 and the contact OB2 (housing portion 23), which interferes with vacuum suction. When the suction nozzle C3 is brought close to the contact OB2 from above, if the suction nozzle C3 comes into contact with the contact OB2, the contact OB2 is pushed down while the burr BR is biting into the pocket, and the contact OB2 is pushed down from the right side and the bottom of the pocket ( There is a possibility that the contact OB2 may be strongly pinched by the portion where the burr BR has bitten into, making it even more difficult to remove the contact OB2 from the pocket portion.

In order to solve the above problem, the embossed tape 4 according to the present embodiment is provided with depressions 41 as shown in FIG. The recess 41 is provided at the left end portion (portion corresponding to the burr BR) of the bottom surface of the pocket portion 12 so as to prevent the burr BR of the contact OB2 from contacting the bottom surface of the pocket portion 12 . The left and front and rear walls of the recess 41 are formed to match the left and front and rear side surfaces of the pocket portion 12 . As a result, the shape of the pocket portion 12 including the recess 41 is simplified by reducing the number of corner portions generated in the pocket portion 12 while providing the recess for avoiding the contact of the burr BR in the pocket portion 12. It is said that press drawing is extremely easy.

In the example of this embodiment, the depth d1 of the pocket portion 12 is about 1.3 mm, while the depth d2 of the recess 41 is set to about 0.1 mm. Due to the provision of such a recess 41, even if the contact OB2 were to be inclined as shown in FIG. slides into the correct position.

The shape and dimensions of the recess 41 are set so that the burr BR does not come into contact with the bottom surface even when the contact OB2 moves within the pocket portion 12 as shown in FIG. That is, the contact OB2 sealed in the pocket portion 12 may move due to an impact or the like within the area surrounded by the side and bottom surfaces of the pocket portion 12 and the cover tape CT. Even if it moves like this, the burr BR will be contained in the recess 41 and the burr BR will not come into contact with the bottom surface. As a result, even if the contact OB2 sealed in the pocket portion 12 moves and tilts once, it slides on the bottom surface and the tilt is eliminated, and the contact OB2 returns to the correct position.

5. Summary As described above, the embossed tapes 1 to 3 according to the first to third embodiments have the pocket portion 12 in which the object to be stored OB is stored. A support projection is provided whose tip in the projecting direction supports the corresponding outer surface of the object to be accommodated OB. Further, the tip portion has a shape that makes point contact or line contact with the corresponding outer surface of the object to be accommodated OB. Therefore, it is possible to make it easier to reduce the contact area between the object OB to be stored in the pocket portion 12 and the bottom surface 12a or the side surface 12b of the pocket portion 12 .

In general, the outer surface of parts of electrical equipment that can be accommodated objects is often planar, and the support projections according to each embodiment support such objects by point contact or line contact. It is a shape suitable for In the first or second embodiment, since the object to be accommodated OB is supported upward only by point contact or line contact with the support projections, the contact area between the object to be accommodated OB and the bottom surface of the pocket portion 12 is minimal. be limited.

The upper ends of the support projections 13a and 13b according to the first embodiment are shaped so as to be in line contact with the object to be accommodated OB, and the upper ends of the support projections 13c to 13h according to the second embodiment are in contact with the object to be accommodated. It has a shape that makes point contact with the OB. It should be noted that the shape of the support projection as viewed from above can be various forms. For example, as shown in FIG. 13, the shape of the support projection 13x when viewed from above is a shape that circles slightly inside the outer periphery of the bottom surface 12a, and the upper end of the support projection 13x is in a shape that makes line contact with the object to be accommodated OB. may be Further, as shown in FIG. 14, four support projections 13p to 13s, which are circular in top view, are arranged near the four corners of the bottom surface 12a, and the upper ends of the support projections 13p to 13s are brought into point contact with the object to be accommodated OB. It is good also as a shape which becomes.

In the same pocket portion 12, even if a support protrusion whose upper end is in line contact with the object to be accommodated OB and a support protrusion whose upper end is in point contact with the object to be accommodated OB coexist. good. As for the shape of the upper end of the support projection, various shapes can be adopted within the range of point contact or line contact with the object to be accommodated.

Further, the tip of the support projection according to each embodiment is formed in a convex curved surface shape that is convex in the projection direction of the support projection. By forming the support projection in such a shape, it is easier to secure the strength of the tip portion and to suppress unnecessary deformation in the vicinity of the tip portion compared to, for example, a case where the upper end is sharpened. In addition, even if there is some variation (inclination) in the direction of the corresponding outer surface, for example, the position slightly deviated from the top of the tip of the support projection contacts the corresponding outer surface, and it is easy to appropriately secure point contact or line contact. becomes. As an example, even if the corresponding outer surface is inclined as indicated by the dashed line in FIG. 7, a position slightly displaced from the top of the tip of the support projection 13a (the position of the line segment La) makes line contact with the corresponding outer surface.

In addition, when the tip of the support projection (protruding direction is defined as "direction D") having a convex curved surface shape is in line contact with the corresponding outer surface of the object to be accommodated, in the direction of the line of line contact In the case where the outer edge shape when viewed is a curved shape that is convex in the direction D and is in point contact with the corresponding outer surface of the object to be accommodated, the outer edge shape when viewed in an arbitrary direction orthogonal to the direction D is convex in the direction D It has a curved shape. In particular, in each of the first to third embodiments, the "convex curved shape" is arc-shaped, so that even if the corresponding outer surface is slightly inclined, the contact form between the two is not changed as much as possible.

In addition, the tip of the support projection according to the first or second embodiment is closer to the projecting direction (here, located in the upper part). Therefore, it is possible to prevent the end of the object to be stored OB from running over the corner portion 12c and to prevent the object to be stored OB from tilting in the pocket portion 12 .

Further, the distal end portion of the side support projection according to the third embodiment is closer to the projecting direction (for example, the first In the case of the side support projection 14a, it is located on the right side). Therefore, it is possible to prevent the end of the object to be stored OB from running over the corner portion 12c and to prevent the object to be stored OB from tilting in the pocket portion 12 .

Note that the pocket portion 12 may be provided with support projections on both the bottom surface 12a and the side surface 12b. For example, in the same pocket portion 12, the bottom surface 12a may be provided with the support projections according to the first or second embodiment, and the side surface 12b may be provided with the side support projections according to the third embodiment. As a result, it is possible to easily reduce the contact area between the inner surface of the pocket portion 12 and the outer surface of both the lower side and the side of the object to be accommodated OB.

In addition, the support projections (or side support projections) of each embodiment support the corresponding outer surface upward (or to the side orthogonal to the vertical direction) to a position where the object OB does not come into contact with the corner portion 12c. It is possible. The arrangement and projection length of each support projection (or side support projection) are set according to the outer surface shape of the object to be accommodated OB so as to support the object to be accommodated OB at a position that does not contact the corner portion 12c. is desirable.

Moreover, the embossed tape 4 according to the fourth embodiment has a pocket portion 12 in which the contact OB2 (object to be accommodated) is accommodated. A recess 41 is provided to avoid contact with the burr BR generated in the . This prevents the burr BR from being caught in the pocket portion 12, suppresses inclination of the contact OB2, and facilitates removal of the contact OB2 from the pocket portion 12. - 特許庁Incidentally, the position where such a recess is provided may be determined according to the position of the burr generated on the object to be accommodated. If the burrs generated on the object to be stored are located at a position where they come into contact with the side surface of the pocket portion, a depression may be provided on the side surface of the pocket portion accordingly. In addition, in this embodiment, the depression is provided to avoid contact with the burr BR, but for example, the depression may be provided to avoid a protrusion intentionally provided as part of the object to be accommodated. can prevent the protrusion from being caught in the pocket.

The configuration of the present invention can be modified in various ways without departing from the gist of the invention, in addition to the above embodiments. That is, the above-described embodiments should be considered as examples in all respects and not restrictive. The technical scope of the present invention is defined by the scope of claims rather than the description of the above embodiments, and is understood to include all modifications within the scope and meaning equivalent to the scope of claims. should.
