Description

Technical Field

[0001] The present invention relates to a container for a wiring circuit board.

Background Art

[0002] Conventionally, a container for housing a wiring circuit board is known. The container has a bottom wall and a peripheral side wall extending upward from the periphery of the bottom wall. The wiring circuit board has an overhanging portion made of an insulating layer. When the wiring circuit board moves within the container, the overhanging portion of the wiring circuit board contacts the peripheral side wall. Thereby, it suppresses the contact of the periphery of the metal support layer with the peripheral side wall, and suppresses the generation of foreign matter due to the contact of the periphery of the metal support layer with the peripheral side wall (see, for example, Patent Document 1 below).

Summary of the Invention

Problems to be Solved by the Invention

[0004] In a container as described in Patent Document 1, when a wiring circuit board having no overhanging portion is housed, there is a possibility that the generation of foreign matter cannot be suppressed.

[0005] Therefore, there may be a demand for a container that can suppress the generation of foreign matter regardless of whether the wiring circuit board has an overhanging portion.

[0006] The present invention provides a container for a wiring circuit board that can suppress the generation of foreign matter due to contact between the edge of the wiring circuit board and the housing portion.

Means for Solving the Problems

[0007] The present invention [1] includes a container for a wiring circuit board for housing a wiring circuit board, comprising: a housing portion capable of housing one wiring circuit board; and a projection disposed within the housing portion and extending in the thickness direction of the wiring circuit board when the wiring circuit board is housed within the housing portion, wherein when the wiring circuit board is housed within the housing portion, the projection faces the edge of the wiring circuit board in a direction perpendicular to the thickness direction of the wiring circuit board.

[0008] With this configuration, when a wiring circuit board is housed in the housing and transported, the movement of the wiring circuit board within the housing can be stopped by the protrusions.

[0009] Therefore, contact between the edge of the wiring circuit board and the side wall of the housing can be reduced.

[0010] As a result, the generation of foreign matter due to contact between the edge of the wiring circuit board and the side wall of the housing can be suppressed.

[0011] The present invention [2] includes the wiring circuit board container of [1], wherein the housing portion has a side wall that is spaced apart from the edge when the wiring circuit board is housed in the housing portion, and the projection is positioned between the edge and the side wall when the wiring circuit board is housed in the housing portion.

[0012] With this configuration, the protrusions can prevent the edges of the wiring circuit board from contacting the side walls of the housing.

[0013] The present invention [3] includes the wiring circuit board container of [2] above, wherein the housing has a bottom wall, and the projection has an inclined surface that slopes away from the side wall as it approaches the bottom wall.

[0014] With this configuration, when housing the wiring circuit board in the housing, the inclined surface can guide the wiring circuit board away from the side wall.

[0015] As a result, when housing the wiring circuit board in the housing, it is possible to suppress contact between the edges of the wiring circuit board and the side walls of the housing.

[0016] The present invention [4] includes the wiring circuit board container described in [3] above, wherein the housing portion has a housing area for housing the wiring circuit board, the projection is located outside the housing area, and the inclined surface is capable of guiding the wiring circuit board toward the housing area when the wiring circuit board is housed in the housing portion.

[0017] With this configuration, the wiring circuit board can be reliably housed in the designated area.

[0018] The present invention [5] includes any one of the wiring circuit board containers described in [1] to [4] above, wherein the wiring circuit board has a plurality of edges, and the wiring circuit board container has at least one projection with respect to each of the plurality of edges.

[0019] With this configuration, contact with the side wall of the housing can be suppressed at all of the multiple edges.

[0020] Therefore, the generation of foreign matter due to contact between the edge of the wiring circuit board and the side wall of the housing can be further suppressed.

[0021] The present invention [6] includes any one of the above [1] to [5] containers for a wiring circuit board, wherein the housing has a bottom wall, and the bottom wall has an opening used for inspecting the wiring circuit board housed in the housing.

[0022] With this configuration, the wiring circuit board can be inspected through the opening while it is housed in the housing.

[0023] The present invention [7] includes the wiring circuit board container [6] described above, wherein, with the wiring circuit board housed in the housing, a portion of the edge of the wiring circuit board overlaps with the opening in the thickness direction of the wiring circuit board.

[0024] According to such a configuration, the edge of the wiring circuit board can be inspected through the opening in a state where the wiring circuit board is accommodated in the accommodating portion.

Effect of the Invention

[0025] According to the container for a wiring circuit board of the present invention, it is possible to suppress the generation of foreign matter due to contact between the edge of the wiring circuit board and the side wall of the accommodating portion.

Mode for Carrying Out the Invention

[0027] 1. Container for Wiring Circuit Board As shown in FIG. 1, the container 1 for a wiring circuit board includes at least one accommodating portion 2. In the present embodiment, the container 1 for a wiring circuit board has a plurality of accommodating portions 2.

[0028] Each of the plurality of accommodating portions 2 can accommodate one wiring circuit board C. That is, the container 1 for a wiring circuit board can accommodate a plurality of wiring circuit boards C. The plurality of accommodating portions 2 are arranged in the first direction and the second direction. The second direction is orthogonal to the first direction. The first direction and the second direction are orthogonal to the vertical direction. In a state where the wiring circuit board C is accommodated in the accommodating portion 2, the wiring circuit board C has a thickness in the vertical direction. That is, in a state where the wiring circuit board C is accommodated in the accommodating portion 2, the first direction and the second direction are orthogonal to the thickness direction of the wiring circuit board C. Hereinafter, one accommodating portion 2A among the plurality of accommodating portions 2 will be described as an example.

[0029] As shown in Figures 2 and 3, in this embodiment, the housing section 2A has a rectangular shape. However, the shape of the housing section 2A is not limited. The housing section 2A has a housing area A, a plurality of side walls 21A, 21B, 21C, 21D, a bottom wall 22, and a plurality of protrusions 23A, 23B, 23C, 23D. In other words, the wiring circuit board container 1 has a plurality of protrusions 23A, 23B, 23C, 23D.

[0030] (1) Full area The housing area A is the area that houses the wiring circuit board C. Housing area A is located in the center of the housing section 2. The shape of housing area A is the same as the shape of the wiring circuit board C. In this embodiment, the wiring circuit board C has a rectangular shape. The wiring circuit board C has multiple edges E1, E2, E3, and E4.

[0031] With the wiring circuit board C housed in the housing section 2A, edge E1 is positioned at one end of the wiring circuit board C in the first direction. Edge E1 extends in the second direction.

[0032] With the wiring circuit board C housed in the housing section 2A, edge E2 is positioned at the other end of the wiring circuit board C in the first direction. Edge E2 extends in the second direction.

[0033] With the wiring circuit board C housed in the housing section 2A, edge E3 is positioned at one end of the wiring circuit board C in the second direction. Edge E3 extends in the first direction.

[0034] With the wiring circuit board C housed in the housing section 2A, edge E4 is positioned at the other end of the wiring circuit board C in the second direction. Edge E4 extends in the first direction.

[0035] (2) Side wall The side wall 21A is positioned at one end of the housing section 2 in the first direction. The side wall 21A extends in the second direction. With the wiring circuit board C housed in the housing section 2A, in the first direction, the side wall 21A faces the edge E1 of the wiring circuit board C at a distance. The side wall 21A also separates two adjacent housing sections 2A and 2B in the first direction.

[0036] The side wall 21B is positioned at the other end of the housing section 2A in the first direction. The side wall 21B extends in the second direction. With the wiring circuit board C housed in the housing section 2A, in the first direction, the side wall 21B faces the edge E2 of the wiring circuit board C at a distance. Also, the side wall 21B separates two adjacent housing sections 2A and 2C in the first direction.

[0037] The side wall 21C is positioned at one end of the housing section 2A in the second direction. The side wall 21C extends in the first direction. With the wiring circuit board C housed in the housing section 2A, in the second direction, the side wall 21C faces the edge E3 of the wiring circuit board C at a distance. The side wall 21C also separates two adjacent housing sections 2A and 2D in the second direction.

[0038] The side wall 21D is positioned at the other end of the housing section 2A in the second direction. The side wall 21D extends in the first direction. With the wiring circuit board C housed in the housing section 2A, in the second direction, the side wall 21D faces the edge E4 of the wiring circuit board C at a distance. Also, the side wall 21D separates two adjacent housing sections 2A and 2E in the first direction.

[0039] (3) Bottom wall As shown in Figure 4, the bottom wall 22 is positioned at the lower end of the housing section 2A. The bottom wall 22 contacts the wiring circuit board C when the wiring circuit board C is housed in the housing section 2A. The bottom wall 22 supports the wiring circuit board C when it is housed in the housing section 2A. The bottom wall 22 extends in a first direction and a second direction. The bottom wall 22 has a plurality of openings 221A, 221B, and 221C. The openings 221A, 221B, and 221C are used for inspecting the wiring circuit board C housed in the housing section 2.

[0040] The opening 221A is used, for example, to inspect whether there are burrs on the edge E1 of the wiring circuit board C. The opening 221A is located at one end of the housing area A in a first direction. With the wiring circuit board C housed in the housing 2A, a portion of the edge E1 overlaps with the opening 221A in the thickness direction of the wiring circuit board C.

[0041] The opening 221B is used, for example, to inspect whether there are burrs on the edge E2 of the wiring circuit board C. The opening 221B is located at the other end of the housing area A in the first direction. With the wiring circuit board C housed in the housing 2A, a portion of the edge E2 overlaps with the opening 221B in the thickness direction of the wiring circuit board C.

[0042] The opening 221C is used, for example, to inspect the position of the wiring circuit board C within the housing section 2A. The opening 221C is located at the other end of the housing area A in a second direction. When the wiring circuit board C is housed in the housing section 2, a portion of the edge E4 of the wiring circuit board C overlaps with the opening 221C in the thickness direction. The opening 221C has a rectangular shape. When the wiring circuit board C is properly housed in the housing section 2, the edge E4 of the wiring circuit board C extends along the edge of the opening 221C. Therefore, by checking the degree of parallelism between the edge of the opening 221C and the edge E4 of the wiring circuit board C, it is possible to inspect whether the wiring circuit board C is housed at an angle.

[0043] Furthermore, the inspections in which openings 221A, 221B, and 221C are used are not limited. Also, the position and size of openings 221A, 221B, and 221C are not limited. The position and size of openings 221A, 221B, and 221C can be changed as appropriate depending on the inspection.

[0044] (4)Protrusion The wiring circuit board container 1 has at least one projection for each of the multiple edges E1, E2, E3, and E4. In this embodiment, the wiring circuit board container 1 has two projections 23A for edge E1, two projections 23B for edge E2, two projections 23C for edge E3, and one projection 23D for edge E4. The multiple projections 23A, 23B, 23C, and 23D are arranged within the housing portion 2A. The multiple projections 23A, 23B, 23C, and 23D are arranged outside the housing area A.

[0045] With the wiring circuit board C housed in the housing section 2A, in the first direction, the projection 23A faces the edge E1 of the wiring circuit board C. With the wiring circuit board C housed in the housing section 2A, in the first direction, the projection 23A is positioned between the edge E1 and the side wall 21A. In this embodiment, the projection 23A is connected to the side wall 21A. The projection 23A is positioned on the opposite side of the projection 23B of the housing section 2C relative to the side wall 21A. In the first direction, the projection 23A is aligned in a straight line with the projection 23B of the housing section 2C. In the second direction, the projection 23A is positioned at the same location as the projection 23B of the housing section 2C. The projection 23A may be separated from the side wall 21A. The two projections 23A are positioned in the second direction with a gap between them. The number of projections 23A is not limited.

[0046] As shown in Figure 4, the projection 23A extends in the vertical direction. When the wiring circuit board C is housed in the housing 2A, the projection 23A extends in the thickness direction of the wiring circuit board C. In this embodiment, the lower end of the projection 23A is connected to the bottom wall 22. The lower end of the projection 23A may be separated from the bottom wall 22. The projection 23A has an inclined surface 231.

[0047] The inclined surface 231 is the side surface of the projection 23A on the side facing the housing area A. The inclined surface 231 extends from the upper end to the lower end of the projection 23A. The inclined surface 231 slopes away from the side wall 21A as it approaches the bottom wall 22. This allows the inclined surface 231 to guide the wiring circuit board C toward the housing area A when the wiring circuit board C is housed in the housing section 2A.

[0048] The explanation for protrusions 23B, 23C, and 23D is the same as the explanation for protrusion 23A. Therefore, the explanation for protrusions 23B, 23C, and 23D is omitted.

[0049] 2. Effects (1) With the wiring circuit board container 1, as shown in Figure 3, when the wiring circuit board C is housed in the housing portion 2A, the projection 23A faces the edge E1 of the wiring circuit board C in the first direction (a direction perpendicular to the thickness direction of the wiring circuit board C).

[0050] Therefore, when transporting the wiring circuit board C in the housing section 2A, the movement of the wiring circuit board C within the housing section 2A can be stopped by the projection 23A.

[0051] This reduces contact between the edge E1 of the wiring circuit board C and the side wall 21A of the housing section 2A.

[0052] As a result, the generation of foreign matter due to contact between the edge E1 of the wiring circuit board C and the side wall 21A of the housing section 2A can be suppressed.

[0053] (2) According to the wiring circuit board container 1, as shown in Figure 3, when the wiring circuit board C is housed in the housing section 2A, the projection 23A is positioned between the edge E1 and the side wall 21A.

[0054] Therefore, the projection 23A prevents the edge E1 of the wiring circuit board C from contacting the side wall 21A of the housing section 2A.

[0055] (3) In the wiring circuit board container 1, as shown in Figure 4, the projection 23A has an inclined surface 231. The inclined surface 231 is inclined away from the side wall 21A as it approaches the bottom wall 22.

[0056] Therefore, when housing the wiring circuit board C in the housing section 2A, the inclined surface 231 can guide the wiring circuit board C away from the side wall 21A.

[0057] As a result, when housing the wiring circuit board C in the housing section 2A, contact between the edge E1 of the wiring circuit board C and the side wall 21A of the housing section 2A can be suppressed.

[0058] (4) With the wiring circuit board container 1, as shown in Figures 3 and 4, the inclined surface 231 can guide the wiring circuit board C toward the housing area A when the wiring circuit board C is housed in the housing section 2A.

[0059] Therefore, the wiring circuit board C can be reliably housed in the housing area A.

[0060] (5) As shown in Figure 3, the wiring circuit board container 1 has at least one projection 23 (projections 23A, 23B, 23C, 23D) for each of the multiple edges E1, E2, E3, E4.

[0061] Therefore, contact with the side walls 21 (side walls 21A, 21B, 21C, 21D) of the housing section 2A can be suppressed at all of the multiple edges E1, E2, E3, and E4.

[0062] Therefore, the generation of foreign matter due to contact between the edges E1, E2, E3, and E4 of the wiring circuit board C and the side wall 21 of the housing section 2A can be further suppressed.

[0063] (6) In the wiring circuit board container 1, as shown in Figure 3, the bottom wall 22 has openings 221A, 221B, and 221C. The openings 221A, 221B, and 221C are used for inspecting the wiring circuit board C housed in the housing section 2A.

[0064] Therefore, while the wiring circuit board C is housed in the housing section 2A, the wiring circuit board C can be inspected through the openings 221A, 221B, and 221C.

[0065] (7) With the wiring circuit board container 1, as shown in Figure 3, when the wiring circuit board C is housed in the housing section 2A, a portion of edge E1 overlaps with the opening 221A and a portion of edge E2 overlaps with the opening 221B in the thickness direction of the wiring circuit board C.

[0066] Therefore, with the wiring circuit board C housed in the housing section 2A, the edge E1 of the wiring circuit board C can be inspected through the opening 221A, and the edge E2 of the wiring circuit board C can be inspected through the opening 221B. [Explanation of Symbols]
