(First embodiment)
Hereinafter, 1st Embodiment of the tape core wire holding component of this invention is described.
As shown in FIG. 8, the tape core holding component 1 includes, for example, a plurality of optical fiber ribbons 2 mounted on the photoelectric composite substrate 29 by shifting the optical path conversion element 3 at the tip in the tape core length direction. Is held in a laminated state. The tape core wire holding component 1 is fixed to a holding component fixture 32 on an apparatus base plate 31 provided with a substrate 29.

The optical path conversion element 3 mounted on the substrate 29 is an optical path converted between the tape core wire 2 wired along the substrate 29 and the optical element (not shown) surface-mounted on the substrate 29. Join.
Reference numeral 4 denotes an optical connector attached to the other end of the tape core wire 2. Reference numeral 33 denotes a base portion of the holding component fixture 32, and reference numeral 34 denotes a lid portion that covers the base portion 33.

  1-7 is a figure which shows the tape core wire holding component 1, and FIG. 1 is a perspective view which shows the tape core wire holding component 1. FIG. 2 and 3 are perspective views showing the press dispersion plate 7 constituting the tape core wire holding component 1. FIG. 4 is a perspective view showing the holding component main body 5 and the lid body 6 constituting the tape core wire holding component 1. FIG. 5 is a schematic view showing a longitudinal section of the tape core wire holding component 1. 6 and 7 are schematic views showing a cross section of the tape core wire holding component 1.

As shown in FIG. 1, the tape core holding component 1 includes a holding component main body 5 that houses a plurality of tape core wires 2 in a stacked state, a lid 6 that covers the holding component main body 5, and a stacked state, as will be described later. A plurality of tape core wires 2 and a pressure dispersion plate 7 disposed between the lid body 6.
The holding component main body 5 includes a bottom portion 10 and wall portions 11 and 11 erected on both side edges in the width direction, and can accommodate the tape core wire 2 inside.

  In the following description, an XYZ orthogonal coordinate system is used as appropriate as shown in FIG. In this coordinate system, the insertion direction of the tape core wire 2 accommodated and inserted in the holding component body 5 is the Y direction, the width direction orthogonal to the insertion direction is the X direction, and the direction orthogonal to the X and Y directions (tape The stacking direction of the core wires 2) is defined as the Z direction.

  In the holding component main body 5, for example, the bottom 10 is a rectangular plate, and the inner surface 10b thereof is flat. For example, the wall 11 is substantially perpendicular to the bottom 10. The constituent material of the holding component main body 5 is preferably a resin, but is not particularly limited. For example, a metal such as stainless steel is also possible.

  The lid body 6 includes a bottom portion 13 and wall portions 14 and 14 erected on both side edges in the width direction. The lid body 6 is put on the holding component main body 5 so that the inside faces each other. The constituent material of the lid 6 is preferably a resin, but is not particularly limited, and a metal such as stainless steel is also possible.

Two types of latch structures 16 and 17 are provided on the wall portion 14 of the lid 6 and the wall portion 11 of the holding component main body 5 so as to engage with each other at the engagement claw and the engagement recess. These latch structures 16 and 17 function at different stages as will be described later, and so-called a two-stage latch structure.
Abutting pieces 11d that can be elastically bent and deformed in the width direction (X direction) are formed on the outer surfaces of both end portions of the walls 11 and 11 so as to extend downward. Is formed with an abutting convex portion 11e that abuts on a post 33b of a holding component fixture 32 described later.

As shown in FIGS. 4 and 5, the lid 6 has a pressing portion 18 that presses the plurality of tape core wires 2 accommodated in the holding component main body 5.
The pressing part 18 has a structure in which a part of the bottom part 13 is shaped like a leaf spring. That is, the pressing portion 18 is provided with slits 13a on both sides in the width direction (X direction) of the bottom portion 13 to separate the width direction intermediate portion from the both side portions, and the cross-sectional shape of the intermediate portion as shown in FIG. The ridge portion 20 has a corrugated portion 21 and 22 on both sides, and further has a ridge portion 21a and 22c on the outer side so that a leaf spring action is produced. Note that the top surface of the peak portion 20 is lower than the top surface 13 b of the bottom portion 13.
Reference numeral 15 denotes end wall portions which are both end portions of the bottom portion 13. Reference numerals 15 a and 15 b denote projecting portions that project from both ends of the bottom portion 13.

As shown in FIG. 8, the lid 6 is pushed down by the lid 34 by, for example, screwing the lid 34 of the holding component fixture 32 to the base 33 of the holding component fixture 32. As a result, the pressing part 18 presses the laminated tape core wire 2 with a large force due to elasticity, and firmly fixes it.
At this time, if the pressure dispersion plate 7 is not present, the lower surfaces 21d and 22d of the valley portions 21 and 22 of the pressing portion 18 are in direct contact with each other, so that a large pressing force is locally applied to the tape core 2 (2A) on the most lid side. It takes. Thereby, not only the tape core wire 2A on the most lid side but also the other tape core wires 2 are locally bent, and the insertion loss of the tape core wire holding component 1 is slightly increased.
On the other hand, as shown in FIGS. 5 to 7, when the rigid pressure dispersion plate 7 is disposed between the pressing portion 18 and the tape core wire 2 closest to the lid, the pressing force is not concentrated locally. And the local bending of the tape core wire 2 can be suppressed, and the insertion loss of the tape core wire holding component 1 can be further reduced.

Since the entire lower surface 21d, 22d of the pressing portion 18 is in contact with the upper surface 26b of the pressure dispersion plate main body 26, the insertion direction (Y direction) length L1 (see FIG. 5) of the pressure distribution plate main body 26 is the valley portions 21b, 22b. It is preferable to make it larger than the distance L2 between the both ends of the whole.
The width direction (X direction) length of the press dispersion plate body 26 is preferably equal to or greater than the width direction (X direction) length of the tape core wire 2. In addition, it is preferable that the length of the pressure dispersion plate 7 has a margin for the relative movement with the lid body 6.

The pressure dispersion plate main body 26 has a rigidity that does not cause a large amount of bending even when the pressing force from the pressing portion 18 is received, and the lower surface 26c comes into contact with the tape core wire 2 (2A) closest to the lid.
With this configuration, as described above, the press dispersion plate main body 26 can disperse the locally large pressing force from the pressing portion 18 and press the tape core wire 2 with a more uniform pressing force. The thickness of the pressure dispersion plate body 26 is preferably 0.05 mm to 0.5 mm, for example.

For example, as shown in FIG. 2, the pressure dispersion plate 7 includes a rectangular flat plate (or substantially flat plate) pressure distribution plate main body 26 and side plate portions 27 and 27 erected from both side edges. For example, the side plate portion 27 is formed substantially perpendicular to the press dispersion plate body 26. In the example of FIG. 2, the side plate portion 27 is further provided with a locking leg portion 25 (locking portion), and the locking leg plate 25 is locked to the lid body 6 by locking the locking leg portion 25 to the lid body 6. It can be attached.
In the example of FIG. 6, the side plate portion 27 can be inserted into the slit 13 a of the lid body 6.
The side plate 27 is restricted from relative movement by hitting the edge of the slit 13a. That is, the side plate portion 27 and the lid body 6 (bottom portion 13) have a regulation structure that regulates relative movement between the press dispersion plate 7 and the lid body 6. With this restricting structure, the position and posture of the pressure dispersion plate 7 can be stabilized.

As shown in FIG. 2, two locking leg portions 25 are formed on the upper edges 27 a and 27 a of the side plate portions 27 and 27, respectively. The locking leg portions 25, 25 of each side plate portion 27 can be plastically bent and deformed inward at positions corresponding to the valley portions 21, 22 with an interval in the insertion direction (Y direction). is there.
2 shows an example of the state of the pressure distribution plate 7 before deformation, and FIG. 3 shows the state of the pressure distribution plate 7 after deformation.
The locking leg portions 25, 25 of each side plate portion 27 can be locked to the valley portions 21, 22 simply by bending inwardly at the base end portion 25a. For this reason, the press dispersion plate 7 can be attached to the lid 6 reliably and easily.
In addition, relative movement can be restricted in the insertion direction because the bent locking leg portions 25, 25 hit the mountain portions on both sides of the valley portions 21, 22. In this case, the locking leg portion 25 and the pressing portion 18 constitute a restricting structure that restricts the relative movement of the pressing dispersion plate 7 and the lid body 6.

As shown in FIG. 5, in order to hold the tape core wire 2 by the tape core wire holding component 1, after the plurality of tape core wires 2 are accommodated in a stacked state inside the holding component main body 5, , Between the lid body 6 and the tape core wire 2 (the tape core wire 2A closest to the lid).
Next, the plurality of tape core wires 2 are held between the lid 6 and the holding component main body 5 by covering the holding component main body 5 so that the inside faces each other.
Each of the tape core wires 2 can be covered with a rubber tube 35.
By using the tape core wire holding component 1, it is possible to easily handle the plurality of tape core wires 2 (optical fiber tape core wire bundles).

As shown in FIGS. 1 and 6, the first latch structure 16 of the two-stage latch structures 16 and 17 is provided at the center of the outer surface 11 c of the wall 11 on both sides of the holding component body 5. It consists of a joint claw 11a and an engagement recess 14a provided at the center part of the wall part 14 on both sides of the lid 6 and engaged with the engagement claw 11a.
The first latch structure 16 is a first-stage latch structure that functions in the engaged state shown in FIG. 6. At this time, the pressing portion 18 that is also the bottom surface (top surface) portion 13 of the lid 6 is laminated. The tape core wire 2 is pressed and elastically deformed by the reaction force received from the tape core wire 2 side.
In the engaged state by the latch structure 16 in the first stage, the laminated tape core wire 2 is lightly pressed to such an extent that it is not misaligned. Therefore, the position of the tape core wire 2 can be adjusted in a state where the lid 6 is engaged with the holding component main body 5 by the latch structure 16.

As shown in FIGS. 1 and 7A, the second latch structure 17 is provided on both sides of the first latch structure 16 in the insertion direction, and the wall portions 11 on both sides of the holding component body 5, respectively. The engaging claw 11b provided on the outer surface 11c of the cover body 6 and the engaging recess 14b provided on the walls 14 on both sides of the lid 6 are engaged with the engaging claw 11b.
The second latch structure 17 is a second-stage latch structure that functions in an engaged state as shown in FIG. 7A when the lid 6 is further pushed down from the state of FIG.
In this state, as shown in FIG. 8, the lid part 34 of the tape core wire holding part 1 is covered with the lid part 34 by screwing the lid part 34 of the holding part fixture 32 to the base part 33 of the holding part fixture 32. Is pressed down further, and the tape core wire 2 on which the pressing portions 18 are laminated is pressed down with a larger elastic force and firmly fixed.
FIG. 7B is a diagram illustrating a state of the first latch structure 16 when the second latch structure 17 is functioning.

In this embodiment, as shown in FIGS. 6, 7, etc., each tape core wire 2 is covered with a rubber tube 35. The rubber tube 35 prevents slippage between the tape core wires 2 and slips between the tape core wire 2 on the most bottom side or the most lid side and the bottom portion 10 of the holding component main body 5 or the pressing portion 18 of the lid body 6. It works as a stop.
In the illustrated example, the rubber tube 35 is covered on all the tape cores 2, but the intermediate tape core 2 excluding the most lid side and the bottommost side is connected to one tape core 2 adjacent vertically. If the rubber tube 35 is covered, the slip prevention works effectively, so that every other rubber tube 35 can be omitted.
Not only the rubber tube but also a rubber material such as a mere rubber sheet is used between the tape core wires, between the tape core wire on the bottom side and the bottom portion 10 and between the tape core wire on the lid side and the bottom portion (top surface portion). ) 13 may be interposed.

At the time of product shipment, the first latch structure 16 is kept in the engaged state without pressing the lid 6 deeply. At this time, the tape core wire 2 is held by the tape core wire holding component 1 so as not to be displaced unnecessarily, but is loose enough to adjust the position of the tape core wire 2.
As shown in FIGS. 8 and 27, when the user holds the tape core holding part 1 holding the laminated tape core 2 on the holding part fixture 32, each tape core holding part 1 is fixed to the holding part. The tool 32 is set on the holding component setting portion 33 a of the base portion 33 of the tool 32.

As shown in FIG. 27, the holding component installation portion 33 a is a space between the posts 33 b erected at positions on both sides in the width direction at both ends in the longitudinal direction of the tape core wire holding component 1 in the base portion 33. The four posts 33b surrounding one tape core holding part 1 regulate the movement in the width direction of both ends of the wall part 11 of the holding part main body 5 in the width direction, and the wall part of the lid 6 in the longitudinal direction. The longitudinal direction movement of both ends in the length direction of 14 is restricted, and the tape core wire holding component 1 is positioned.
The contact protrusion 11e is pressed against the post 33b by the elastic force of the contact piece 11d (see FIG. 1) of the holding component body 5. When the movement of the tape core wire holding component 1 in the height direction (Z direction) is restricted by the friction between the abutting convex portion 11e and the post 33b, the tape core wire holding component 1 is moved to the holding component installation portion 33a. It is kept stable.

Next, the tape core wire holding component 1 is fixed to the holding component fixing tool 32 by screwing the lid portion 34 of the holding component fixing device 32 to the lid fixing portion 33 c (see FIG. 27) of the base portion 33.
At this time, the optical connector 3 attached to each of the tape core wires 2 held by the tape core wire holding component 1 can be accurately positioned and installed at a position to be mounted on the substrate 29.
If the position of the optical connector 3 deviates from the position to be mounted, the latch structure 16 in the first stage is loose enough to adjust the tape core wire 2, so that the tape core wire holding component 1 is held by the holding component. The second stage latch structure 17 is released from the fixture 33, and the first stage latch structure 16 remains with the engaged lid body 6, and the position of the laminated tape core 2 is readjusted. .

As described above, according to the tape core wire holding component 1, since the tape core wire 2 can be held only by the operation of covering the lid body 6, the operation of stacking and holding the tape core wires is easy. .
Further, since the second stage latch structure 17 is released and the first stage latch structure 16 remains with the engaged lid 6, the position of the tape core 2 can be readjusted. Work is easy.
Like conventional heat-shrinkable tubes, heating work is unnecessary and work is easy, and the lid can be removed and the position of the tape core can be readjusted. However, it is possible for the user side to easily and highly accurately perform positioning and hold the tape core wire in a stacked manner.

  The pressing portion 18 of this embodiment is configured by making the shape of the top surface portion 13 itself of the lid 6 into a leaf spring shape, but is not limited thereto, for example, a rubber sheet is attached to the inner surface of the flat top surface portion, etc. Other means can be employed.

(Second Embodiment)
Next, the tape core wire holding component 41 of the second embodiment will be described.
In the description of each embodiment to be described below, the same reference numerals are given to the already described configurations, and the description thereof may be omitted.
FIG. 9 is a perspective view showing the press dispersion plate 40 of the tape core wire holding component 41, and FIG. 10 is a schematic view showing a longitudinal section of the tape core wire holding component 41.
The tape core wire holding component 41 of this embodiment has the same configuration as the tape core wire holding component 1 shown in FIG. 1 except that the press dispersion plate 40 is used instead of the press dispersion plate 7.

As shown in FIG. 9, the pressure distribution plate 40 includes a rectangular flat plate-shaped pressure distribution plate main body 46, and a side plate portion that extends substantially perpendicularly from the side edge 46 a of the pressure distribution plate main body 46 to the pressure distribution plate main body 46. 47 and a locking claw portion 45 formed on the upper edge 47a of the side plate portion 47.
The pressure dispersion plate main body 46 has a rigidity that does not cause a large amount of bending even when the pressing force from the pressing portion 18 is received, and the lower surface 46c comes into contact with the tape core wire 2 (2A) closest to the lid.

Two locking claws 45 are formed on the upper edges 47a and 47a of the side plate portions 47 and 47, respectively.
The locking claw portions 45, 45 of each side plate portion 47 approach the pressure distribution plate main body 46 inwardly at positions corresponding to the valley portions 21, 22 at intervals in the insertion direction (Y direction). However, it is formed to extend while tilting.
By locking the locking claw portion 45 to the valley portions 21 and 22, the relative movement of the pressing dispersion plate 40 and the lid body 6 in the insertion direction can be restricted.

The locking claw portion 45 can be elastically bent and deformable.
According to this configuration, for example, when the pressing dispersion plate 40 is attached to the pressing portion 18 from the lower surface side, the locking claw portion 45 is restored by the elastic force after getting over the pressing portion 18 while bending and deforming in the folding direction. The movement of the dispersion plate 40 can be regulated. For this reason, the operation of attaching the pressure dispersion plate 40 is facilitated.

The side plate portion 47 can be inserted into the slit 13a.
In the example shown in FIG. 10, the side plate portion 47 has its end edge 47 b (movement restricting portion) abutting against the edges 13 c at both ends of the slit 13 a (inner surface of the end wall portion 15) so that movement in the insertion direction is restricted. Thus, the side plate portion 47 of the pressure dispersion plate 40 and the bottom portion 13 of the lid body 6 constitute a restriction structure that restricts relative movement in the insertion direction (Y direction). .
With this restricting structure, the position and posture of the pressure dispersion plate 40 can be stabilized.
As a constituent material of the pressure dispersion plate 40, an elastically bendable material, that is, a metal such as stainless steel, a resin, or the like can be used.

  As shown in FIG. 10, the force by the pressing part 18 is concentrated locally by disposing the pressing dispersion plate main body 46 between the pressing part 18 of the lid body 6 and the tape core wire 2 (2A) closest to the lid body. Accordingly, the bending loss of the tape core wire 2 can be suppressed, and the insertion loss can be further reduced.

(Third embodiment)
Next, the tape core wire holding component 51 of the third embodiment will be described.
FIG. 11 is a perspective view showing the press dispersion plate 50 of the tape core wire holding component 51, and FIG. 12 is a schematic view showing a longitudinal section of the tape core wire holding component 51.
The tape core wire holding component 51 of this embodiment has the same configuration as the tape core wire holding component 1 shown in FIG. 1 except that the press dispersion plate 50 is used instead of the press dispersion plate 7.

As shown in FIG. 11, the press dispersion plate 50 includes a rectangular flat plate-like press dispersion plate main body 56, and a side plate portion that extends substantially perpendicularly from the side edge 56 a of the press dispersion plate main body 56 to the press dispersion plate main body 56. 57 and a locking claw portion 55 formed on the upper edge 57a of the side plate portion 57.
The pressure dispersion plate main body 56 has a rigidity that does not cause a large amount of bending even when the pressing force from the pressing portion 18 is received, and the lower surface 56c comes into contact with the tape core wire 2 (2A) closest to the lid.
The locking claw portion 55 has the same configuration as that of the locking claw portion 45 shown in FIGS. 9 and 10, is elastically bendable, and inclines while approaching the pressure distribution plate body 56 toward the inside. Are formed on the upper edges 57a and 57a of the side plate portions 57 and 57, respectively.
As shown in FIG. 12, the locking claw portion 55 can be locked to the valley portions 21 and 22, thereby restricting relative movement of the pressing dispersion plate 50 and the lid body 6 in the insertion direction.

The pressure dispersion plate 50 has a pressure dispersion plate body 56 formed longer in the insertion direction than the pressure dispersion plate 40 shown in FIGS. 9 and 10.
For this reason, even when the position shift in the insertion direction occurs, the tape core wire 2 can be reliably held.
As a constituent material of the pressure dispersion plate 50, an elastically bendable material, that is, a metal such as stainless steel, a resin, or the like can be used.

  As shown in FIG. 12, by placing the pressure dispersion plate body 56 between the pressing portion 18 of the lid 6 and the tape core wire 2 (2A) closest to the lid, the force by the pressing portion 18 is concentrated locally. Accordingly, the bending loss of the tape core wire 2 can be suppressed, and the insertion loss can be further reduced.

(Fourth embodiment)
Next, the tape core wire holding component 61 of the fourth embodiment will be described.
FIG. 13 is a diagram schematically showing the lid 67 of the tape core wire holding component 61 and the undeformed press dispersion plate 60 that is integrally connected to the lid 67 and extends from one end of the lid 67. 14 is a schematic view showing a longitudinal section of the tape core wire holding component 61. FIG.
The tape core holding component 61 of this embodiment is the same as the tape core holding component 1 shown in FIG. 1 except that the lid 67 and the press dispersion plate 60 are used instead of the lid 6 and the press dispersion plate 7. It is the same composition.

The lid body 67 has the same configuration as the lid body 6 of the tape core wire holding component 1 shown in FIG. 1 except that a pressing portion 63 having one valley portion 62 is used instead of the pressing portion 18.
