The optical fiber 20 has a plurality of taped end portions 23 in which four optical fibers 20 are taped in accordance with the corresponding optical connector 30A with a tape core wire on one end side. Similarly, the optical fiber 20 forms a plurality of taped ends 25 in which the four optical fibers 20 are taped according to the corresponding optical connector 30B with a tape core wire on the other end side. . In each of the taped ends 23 and 25, the four optical fibers 20 are arranged along the width direction (the direction in which the pair of side walls face each other). The combination of the four optical fibers 20 constituting the taped end portion 23 on the one end side and the combination of the four optical fibers 20 constituting the taped end portion 25 on the other end side are different from each other. The taped end portions 23 are arranged along the width direction of each other. The taped end portions 25 are arranged along the width direction of each other.

  The taped ends 23 and 25 are positioned in the internal space S of the housing 10. In the present embodiment, the taped ends 23 and 25 are positioned at the edge of the wiring part S1. That is, the plurality of taped end portions 23 are positioned at the front edge portion Sa of the wiring portion S1, and the plurality of taped end portions 25 are positioned at the rear edge portion Sb of the wiring portion S1. The taped ends 23 and 25 may be fixed to the housing via a fixing member that can be fixed to the housing 10, or may be fixed to the housing 10 with an adhesive or the like.

  Next, details of the optical connectors 30A and 30B with the tape core wires will be described. In the present embodiment, the optical connector with tape core 30A and the optical connector with tape core 30B have substantially the same configuration. Each of the optical connectors 30 </ b> A and 30 </ b> B with a tape core wire includes a tape core wire 33 and an optical connector 35. The tape core wire 33 is taped (ribboned) in a state where a plurality of optical fibers are arranged in one direction. Hereinafter, the direction in which the plurality of optical fibers are arranged may be referred to as the width direction of the tape core wire. In the tape core 33 of the present embodiment, four optical fibers (single cores) 34 are taped in the same manner as the taped ends 23 and 25. The arrangement direction of the optical fibers in the tape core wire 33 is the same as the arrangement direction of the optical fibers 20 in the taped ends 23 and 25. The plurality of tape cores 33 are arranged in a state of being separated from each other along the width direction of each other.

  One end of the tape core wire 33 is disposed in one of the extra length processing regions S2 and S3 of the housing 10 through the opening 10a or the opening 10b. In the present embodiment, one end of each of the tape cores 33 constituting the four optical connectors with tape cores 30A is inserted from the front opening 10a into the extra length processing region S2. In addition, one end of each of the tape cores 33 constituting the four optical connectors with tape cores 30B is inserted from the rear opening 10b into the extra length processing region S3.

  In the surplus length processing regions S2 and S3, at least a part of the plurality of optical fibers 34 constituting the tape core wire 33 is separated from each other. In the present embodiment, the four optical fibers 34 are separated from each other in a predetermined region in the length direction. Further, four optical fibers 34 are restrained at one end of the tape core wire 33. In the illustrated example, one end of the tape core wire 33 is a taped end portion 33a. 2 and 3, only the taped portion of the tape core wire 33 is shown, and the portion separated from the single core is omitted.

  The taped end portion 33a is connected to the corresponding taped end portions 23 and 25. In the present embodiment, the taped ends 33a of the four tape cores 33 constituting the four optical connectors with tape cores 30A correspond to the four taped ends 23, respectively. Further, the taped ends 33a of the four tape cores 33 constituting the four optical connectors 30B with the tape cores correspond to the four taped ends 25, respectively. As an example, the taped end portion 33 a is fusion-bonded to the corresponding taped end portions 23 and 25. In this case, the connecting portion can be covered by a protective sleeve, which is a sleeve that reinforces the optical fiber.

  Optical connectors 35 are connected to the other ends of the plurality of tape core wires 33, respectively. For example, the optical connector 35 is a multi-fiber optical connector, and in this embodiment, is a 4-fiber MT connector that collectively accommodates four optical fibers arranged in one direction.

  The tape core wire 33 is detachably positioned by the positioning portion 40 provided at the edge on the opening side in the extra length processing regions S2 and S3. The positioning part 40 has a clamping part 43 for clamping and positioning a taped portion of the tape core wire 33 in the thickness direction. The positioning portion 40 is configured by front walls 14a and 18a and rear walls 14b and 18b provided in the openings 10a and 10b. In this case, the surplus length processing region S2 extends from the front edge portion Sa of the wiring portion S1 to the opening 10a. Similarly, the surplus length processing area S3 extends from the rear edge Sb of the wiring part S1 to the opening 10b.

  3 is an exploded cross-sectional view showing a state in which the optical wiring member of FIG. 2 is disassembled. The front walls 14a and 18a and the rear walls 14b and 18b are formed of an elastic material that is elastically deformed. As shown in FIG. 3, the heights of the front walls 14a, 18a and the rear walls 14b, 18b are higher than the heights of the side walls 13a, 13b, 17a, 17b in the natural state. As an example, the front walls 14a and 18a and the rear walls 14b and 18b may be formed of sponge, rubber, or the like. FIG. 4 is a perspective view partially showing the optical wiring member 1. As shown in FIG. 4, in the state where the housing 10 is configured, the front walls 14 a and 18 a and the rear walls 14 b and 18 b are deformed so as to be pressed against each other by the pair of plate-like parts 12 and 16. ing. That is, the openings 10a and 10b of the housing 10 can be closed by the front walls 14a and 18a and the rear walls 14b and 18b. The tape core wire 33 passing through the opening 10a is sandwiched and positioned by a sandwiching portion 43 constituted by the front wall 14a of the first housing 11 and the front wall 18a of the second housing 15. The tape core wire 33 passing through the opening 10b is sandwiched and positioned by a sandwiching portion 43 constituted by the rear wall 14b of the first housing 11 and the rear wall 18b of the second housing 15.

  In the optical wiring member 1 described above, between the edge portions (the front edge portion Sa and the rear edge portion Sb) of the wiring portion S1 set in the internal space S of the housing 10 and the openings 10a and 10b of the housing 10. Extra length processing areas S2 and S3 are formed. For example, one end of the tape core wire 33 inserted into the opening 10a of the housing 10 is connected to the corresponding taped end portion 23 through the extra length processing region S2. Thus, the tape core wire 33 having the optical connector 35 connected to the other end is connected to the corresponding plurality of optical fibers 20. In one embodiment, the tape core wire 33 is positioned by the positioning portion 40 in the opening 10a that is the edge of the surplus length processing region S2. Further, the taped end portion 23 connected to the tape core wire 33 is positioned at the front edge portion Sa of the wiring portion S1. Here, since the positioning part 40 can position the tape core wire 33 so that attachment or detachment is possible, it can adjust the slack of the tape core wire 33 arrange | positioned in surplus length process area | region S2. In the extra length processing areas S2 and S3, since at least a part of the plurality of optical fibers 34 constituting the tape core wire 33 is separated from each other, the tape core wire 33 can be easily crossed in the length direction. Can bend. Even if the optical fibers 34 are not separated from each other, the tape core wire can bend in the thickness direction. In particular, in the above embodiment, the optical fiber 34 is separated from the optical fiber 34. Therefore, it can be easily bent in any direction intersecting the length direction. In this case, even if the thickness of the housing 10 is small, the slack of the tape core wire 33 can be adjusted by bending the optical fiber 34 in the width direction. Thereby, since the length of the tape core wire 33 from the extra length processing area S2 to the optical connector 35 can be controlled, the length from the wiring portion S1 to the optical connector 35 can be controlled. For example, the length from the wiring part S1 to the optical connector 35 is shortened by bringing the position sandwiched by the positioning part 40 closer to the optical connector 35 side of the tape core wire 33. On the contrary, the distance from the wiring part S1 to the optical connector 35 is increased by moving the position sandwiched by the positioning part 40 away from the optical connector 35.

  The taped ends 23 and 25 are fused to one end of the tape core 33 of the corresponding optical connector 30 with a tape core. Since the taped end and the tape core wire 33 are optically connected by fusion, they can be easily manufactured. In this case, a fusion sleeve is provided at the fusion portion between the taped end and the tape core wire 33. The fusion sleeve can be disposed in the internal space S of the housing 10 including the extra length processing regions S2 and S3.

[Second Embodiment]
The optical wiring member 101 according to the present embodiment is different from the optical wiring member of the first embodiment in that it includes a binding member that binds a plurality of single-core wires separated from each other. In the following, differences from the first embodiment will be mainly described, and the same elements and members will be denoted by the same reference numerals and detailed description thereof will be omitted.

  FIG. 5 is a cross-sectional view showing the optical wiring member 101 according to this embodiment. The optical wiring member 101 includes a housing 10, a plurality of optical fibers 20, a plurality of optical connectors 30 (30 </ b> A, 30 </ b> B) with tape core wires, and a binding member 37.

  The binding member 37 binds together a plurality of optical fibers 34 separated from each other. For example, the bundling member 37 bundles a plurality of (four in the illustrated example) optical fibers 34 constituting at least one tape core wire 33 at a time. In the example shown in FIG. 5, the bundling member 37 bundles a plurality of (eight in the illustrated example) optical fibers 34 constituting two tape cores 33 arranged adjacent to each other. In this configuration, it is possible to suppress the optical fiber 34 from being congested in a complicated manner, and to reduce the risk of disconnection of the optical fiber 34.

  The binding member 37 may be configured by a member that can form an annular shape, such as a spiral tube, a contraction tube, or a binding band. The spiral tube has a long annular shape by its own elastic force in a natural state, and can be formed into a long plate shape by being spread against the elastic force. The contraction tube has an annular shape with a predetermined diameter in a natural state, and becomes an annular shape with a large diameter by being pushed against the elastic force. Or a shrink tube becomes a small-diameter annular | circular shape by heating. The binding band becomes an annular body having an arbitrary diameter by inserting the other end of the band into a fixing hole provided at one end of the long band and tightening the band. By configuring the binding member 37 with a spiral tube, a contraction tube, a binding band, or the like, the optical fibers 34 can be easily bundled.

[Third Embodiment]
The optical wiring member 201 according to the present embodiment is different from the optical wiring member of the first embodiment in that a plurality of single core wires are intermittently bonded to each other in the extra length processing region. In the following, differences from the first embodiment will be mainly described, and the same elements and members will be denoted by the same reference numerals and detailed description thereof will be omitted.

  FIG. 6 is a cross-sectional view showing the optical wiring member 201 according to this embodiment. The optical wiring member 201 includes a housing 10, a plurality of optical fibers 20, and a plurality of optical connectors 30 (30A, 30B) with tape core wires.

  The optical connector 30 with a tape core wire includes an optical connector 35 and a tape core wire 33. In the tape core 33, four optical fibers (single cores) 39 similar to the optical fiber 34 in the first embodiment are taped. That is, the configuration of the taped end 33a formed at one end of the tape core wire 33 is the same as the taped end 33a in the first embodiment. In the present embodiment, four optical fibers 39 are intermittently bonded to each other in a predetermined region in the length direction in the surplus length processing regions S2 and S3. That is, in the four optical fibers 39 arranged in parallel in one direction, the adjacent optical fibers 39 are intermittently bonded to each other in the longitudinal direction. When attention is paid to one set of optical fibers 39, the bonding position of one adjacent optical fiber 39 and the bonding position of the other adjacent optical fiber 39 are shifted from each other in the length direction.

  In the above configuration, since some of the optical fibers 39 are separated from each other, the tape core wire 33 can be easily bent in a direction intersecting the length direction. Moreover, since the optical fibers 39 are not separated from each other, the risk of disconnection can be reduced.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, a specific structure is not restricted to this embodiment.

  For example, the height of the front walls 14a and 18a and the rear walls 14b and 18b forming the sandwiching portion 43 is higher than that of the side walls 13a, 13b, 17a and 17b, but the present invention is not limited to this. For example, the positioning portion may be formed by the front wall and the rear wall in a state where the housing is configured. That is, it is only necessary that the tape core wire can be held between the front wall (rear wall) of the first housing and the front wall (rear wall) of the second housing in a state where the housing is configured. For example, the height of the front wall and the rear wall may be the same as the side wall, and the height of the front wall and the rear wall may be lower than the side wall.

  Moreover, although the positioning part 40 showed the example provided with the clamping part 43 formed by the front walls 14a and 18a and the rear walls 14b and 18b, it is not limited to this. The positioning portion only needs to be able to fix the tape core wire at a position closer to the opening than the edge portion of the wiring portion in the internal space. For example, the positioning part may be a clip or the like disposed in the opening. In this case, the tape core can be fixed by the clip, and the relative position between the tape core and the housing can be arbitrarily changed while the clip is loosened.

  Moreover, although the example in which the openings 10a and 10b of the housing 10 are provided so as to face each other is shown, the present invention is not limited to this. For example, the two openings may be formed on the wall surfaces orthogonal to each other in the housing.

  Moreover, although the example in which the number of optical connectors with tape cores inserted through one opening 10a and the number of optical connectors with tape cores inserted through the other opening 10b is the same is shown, the present invention is not limited to this. The number of optical connectors with cores may be different from each other. In order to simplify the description, the example in which the number of the optical fibers 20 in the wiring portion S1 is 16 is shown, but the present invention is not limited to this. Moreover, although the some optical connector 35 showed the example which is a 4 core MT connector, it is not limited to 4 cores. Further, the plurality of optical connectors 35 may be MT connectors having different numbers of cores.
