JP 2002-290070 A

  In the optical fiber wiring method using the wire protector, first, the base member is fixed to the wall surface, and the cover member is attached to the base member while accommodating the optical fiber. In addition, the base member and the cover member having a certain length are connected and cut along the wiring route. A wire protector for the bent portion is necessary at the place where the optical fiber is bent and wired, and the construction efficiency is not good because the member is changed between the straight portion and the bent portion. In addition, since the optical fiber is accommodated after the wire protector is installed along the wiring route, the conventional optical fiber wiring requires two processes such as installation of the optical fiber wiring component and accommodation of the optical fiber at the construction site. Improvement of construction efficiency was an issue.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an optical fiber wiring tool capable of reducing the number of construction steps and realizing optical fiber wiring and improving the construction efficiency.

  In order to achieve the above object, an optical fiber wiring tool of the present invention comprises an optical fiber provided with a protective coating and an adhesive tape bonded along the longitudinal direction of the optical fiber and provided with an adhesive on the back surface. It is characterized by comprising.

  Further, the optical fiber wiring tool of the present invention is bonded to the optical fiber housing member in which the optical fiber is housed along the longitudinal direction and the longitudinal direction of the optical fiber housing member, and an adhesive is provided on the back surface. And an adhesive tape.

  The optical fiber wiring tool of the present invention is bonded to a removable optical fiber housing member in which an optical fiber is removably accommodated along the longitudinal direction, and the longitudinal direction of the removable optical fiber housing member. And an adhesive tape provided with an adhesive on the back surface.

  According to the present invention, in the optical fiber wiring tool, a cut portion in which a part of the adhesive tape is cut is provided in a part in the longitudinal direction of the optical fiber.

  According to the present invention, in the optical fiber wiring tool, a cut portion in which a part of the optical fiber housing member and the adhesive tape is cut is provided in a part in the longitudinal direction of the optical fiber.

  In the optical fiber wiring tool according to the present invention, the removable portion of the optical fiber housing member and the adhesive tape are partly cut off in a part of the longitudinal direction of the optical fiber. It is.

  According to the present invention, in the optical fiber wiring tool, as the optical fiber, an optical fiber in which a tension member is disposed in parallel with the optical fiber core wire and covered with a protective coating is used.

  In the optical fiber wiring tool according to the present invention, an optical fiber cord in which a tension member is disposed around an optical fiber core wire and covered with a protective coating is used as the optical fiber.

  The present invention is, for example, an optical fiber wiring tool for constructing an optical fiber on a wall surface or the like in a house. Since the construction is performed in a state where the optical fiber and the tape part to be bonded to the wall surface are integrated, it can be applied to the wall surface in one step Optical fiber wiring can be realized and construction efficiency is improved. Moreover, since it can respond by the same member in a linear part and a bending part, not only construction efficiency improves but it also enables the low cost of an optical fiber wiring tool. In particular, when wiring using optical fiber cores that have been coated with a UV curable resin and made transparent, the members other than the optical fiber cores are also made transparent so that the wiring is not conspicuous in the house and has excellent aesthetics. Fiber wiring can be realized.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a structural explanatory perspective view showing an optical fiber wiring tool according to a first embodiment of the present invention. As shown in FIG. 1, the optical fiber 11 is provided with a protective coating 12 made of an ultraviolet curable resin or the like, and the protective coating 12 of the optical fiber 11 is bonded to the surface of the adhesive tape 13 along the longitudinal direction. An adhesive is provided on the back surface of the adhesive tape 13.

  That is, when constructing the optical fiber 11 on the wall surface in the house, the optical fiber wiring tool integrated by bonding the optical fiber 11 to the surface of the adhesive tape 13 is used, and the adhesive on the back surface of the adhesive tape 13 is adhered to the wall surface. Install. Therefore, the wiring of the optical fiber 11 to the wall surface can be realized in one process, and the construction efficiency is improved.

  When an ultraviolet curable resin is used as the protective coating 12 of the optical fiber 11 and a double-sided adhesive tape is used as the adhesive tape 13, the outer diameter of the optical fiber 11 is mainly 0.25 mm, 0.5 mm, or 0.9 mm. It is done. The width of the double-sided adhesive tape is made larger than the outer diameter of the optical fiber 11. For example, the width of the double-sided adhesive tape is 1 mm or more. The optical fiber 11 is bonded to the double-sided adhesive tape while sinking. This is to increase the bonding area between the circular optical fiber 11 and the double-sided adhesive tape. The surface to which the optical fiber 11 is bonded has a structure in which the adhesive layer is not exposed except for the portion to which the optical fiber 11 is bonded. For example, a double-sided adhesive tape is prepared without previously applying an adhesive except for a portion where the optical fiber 11 is bonded. Alternatively, the exposed portion of the adhesive layer is closed by placing a sheet on the adhesive layer where the optical fiber 11 is not bonded and exposed. By exposing the adhesive layer, there is an effect of preventing dust from adhering to the adhesive layer and impairing the aesthetics. Before construction, a sheet is placed on the adhesive layer side to be adhered to the wall surface of the double-sided adhesive tape in order to prevent dust from adhering. At the time of construction, the optical fiber wiring tool is attached to the wall surface while peeling off the sheet on the adhesive layer side to be bonded to the wall surface of the double-sided adhesive tape.

  Therefore, since the optical fiber wiring component and the optical fiber are integrated, the optical fiber wiring is realized in one process. Further, when the optical fiber is coated with an ultraviolet curable resin, the optical fiber is transparent. By using a transparent member for the double-sided adhesive tape member, the optical fiber wiring tool becomes transparent, and in particular, it is possible to realize optical fiber wiring in a house with excellent aesthetics.

  Note that, in place of the optical fiber 11, when an optical fiber cord in which the periphery of the optical fiber core wire is covered with a tension member and covered with a protective coating is used, it can be carried out in the same manner as when the optical fiber 11 is used. Since the outer diameter of the optical fiber cord is 1.1 mm or 2.0 mm, the width of the double-sided adhesive tape needs to be larger than when the optical fiber 11 is used. For example, when an optical fiber cord is used, the width of the double-sided adhesive tape is 3 mm or more.

  FIG. 2 is a structural explanatory perspective view showing an optical fiber wiring tool according to a second embodiment of the present invention. As shown in FIG. 2, tension members 22 are arranged in parallel on both sides along the longitudinal direction of the optical fiber core 21, and the optical fiber core 21 and the tension member 22 are covered with a protective coating 23 to cover indoor light. A fiber 24 is constructed. The protective coating 23 is adhered to the surface of the adhesive tape 25 along the longitudinal direction, and an adhesive is provided on the back surface of the adhesive tape 25.

  That is, when the indoor optical fiber 24 is applied to the wall surface in the house, an optical fiber wiring tool in which the protective coating 23 is bonded to the surface of the adhesive tape 25 and the adhesive tape 25 and the indoor optical fiber 24 are integrated is used. 24 Adhere the adhesive on the back to the wall. Therefore, the wiring of the indoor optical fiber 24 to the wall surface can be realized in one process, and the construction efficiency is improved.

  An indoor optical fiber has a rectangular cross section. One side of the double-sided adhesive tape is bonded to the surface of the long side having a length of more than 3 mm. In FIG. 2, a double-sided adhesive tape having the same width as the indoor optical fiber is used. However, when a larger area of adhesion to the wall surface is required, a double-sided adhesive tape wider than the indoor optical fiber is used. In the case of using a double-sided adhesive tape wider than the indoor optical fiber, the double-sided adhesive tape is prepared without previously applying an adhesive except for the portion where the indoor optical fiber is bonded. Alternatively, the sheet is placed on the adhesive layer where the indoor optical fiber is exposed without being bonded. By exposing the adhesive layer, there is an effect of preventing dust from adhering to the adhesive layer and impairing the aesthetics. Before construction, a sheet is placed on the back of the double-sided adhesive tape that adheres to the wall surface in order to prevent dust from adhering to the adhesive layer side. At the time of construction, the optical fiber wiring tool is attached to the wall surface while peeling off the sheet on the adhesive layer side of the back surface of the double-sided adhesive tape that adheres to the wall surface. Since the optical fiber wiring component and the indoor optical fiber are integrated, the wiring of the indoor optical fiber is realized in one process.

  In place of the optical fiber 11, an indoor optical fiber was also used when a drop optical fiber was used in which a tension member was arranged in parallel with the optical fiber core and covered with a protective coating, and further along the support line. It can be carried out in the same way as the case. Since the drop optical fiber is drawn into the house with the support line separated, it is the same as the form using the indoor optical fiber.

  FIG. 3 is a structural explanatory perspective view showing an optical fiber wiring tool according to a third embodiment of the present invention. As shown in FIG. 3, the optical fiber 31 is provided with a protective coating 32 made of an ultraviolet curable resin or the like, and the optical fiber 31 is accommodated in the optical fiber accommodating member 33 along the longitudinal direction. The optical fiber housing member 33 is formed of a long and narrow quadrangular prism, and is formed by providing a through hole 34 having a circular cross section at the center shaft portion, and the optical fiber 31 is inserted into the through hole 34 and housed. The optical fiber housing member 33 is bonded to the surface of the adhesive tape 35, and an adhesive is provided on the back surface of the adhesive tape 35.

  That is, when the optical fiber 31 is constructed on the wall surface in the house, an optical fiber wiring tool in which the optical fiber housing member 33 is bonded and integrated on the surface of the adhesive tape 35 is used, and the adhesive on the back surface of the adhesive tape 35 is applied to the wall surface. Glue and install. Therefore, the wiring of the optical fiber 31 to the wall surface can be realized in one process, and the construction efficiency is improved.

  In order to facilitate the insertion of the optical fiber 31 into the through hole 34 of the optical fiber housing member 33, the diameter of the through hole 34 is made larger than the outer diameter of the optical fiber 31, and the optical fiber 31 is gently held inside the through hole 34. It has a structure. The optical fiber housing member 33 is made by extrusion molding using synthetic resin as a material. In the factory, the surface of the double-sided adhesive tape is bonded to the optical fiber housing member 33, the optical fiber 31 is housed in the optical fiber housing member 33, and the sheet is placed on the back side of the double-sided adhesive tape to be bonded to the wall surface Bring it to the construction site. At the time of construction, the optical fiber wiring tool is attached to the wall surface while peeling off the sheet on the back side of the double-sided adhesive tape that adheres to the wall surface. Since the optical fiber wiring component and the optical fiber are integrated, the optical fiber wiring is realized in one process. When the optical fiber is coated with an ultraviolet curable resin, the optical fiber becomes transparent. By using a transparent member as the optical fiber housing member, the optical fiber wiring tool becomes transparent, and in-house optical fiber wiring with particularly excellent aesthetics can be realized.

  In addition, when an optical fiber cord is used instead of the optical fiber 31, it can carry out similarly to the case where the optical fiber 31 is used. Since the outer diameter of the optical fiber cord is 1.1 mm or 2.0 mm, the size of the optical fiber housing member is increased as compared with the case where the optical fiber 31 is used, and the diameter of the through hole needs to be increased.

  In addition, when an indoor optical fiber or a drop optical fiber is used instead of the optical fiber 31, it can be implemented in the same manner as when the optical fiber 31 is used. When an indoor optical fiber or a drop optical fiber is used, the shape of the through hole of the optical fiber housing portion is rectangular according to the outer shape of the indoor optical fiber or the drop optical fiber.

  FIG. 4 is a structural explanatory perspective view showing an optical fiber wiring tool according to a fourth embodiment of the present invention. As shown in FIG. 4, the optical fiber 41 is provided with a protective coating 42 made of an ultraviolet curable resin or the like, and the optical fiber 41 is accommodated in the optical fiber accommodation member 43 along the longitudinal direction. The optical fiber housing member 43 is formed of an elongated rectangular tube, a through hole 44 having a square cross section is provided in the central shaft portion, and a split portion 45 for entering and exiting the optical fiber is provided on the surface of the through hole 44 in the axial direction. The split portion 45 has a shape in which two cantilever portions overlap each other, and once the optical fiber 41 is inserted, it does not jump out of the optical fiber housing member 43 unless the optical fiber 41 is intentionally taken out. . The optical fiber 41 is inserted and accommodated in the through hole 44. The optical fiber housing member 43 is bonded to the surface of the adhesive tape 46, and an adhesive is provided on the back surface of the adhesive tape 46.

  That is, when constructing the optical fiber 41 on the wall surface in the house, an optical fiber wiring tool in which the optical fiber accommodating member 43 into which the optical fiber 41 is inserted and accommodated is bonded to the surface of the adhesive tape 46 and integrated is used. 46 Adhere the adhesive on the back to the wall. Therefore, the wiring of the optical fiber 41 to the wall surface can be realized in one process, and the construction efficiency is improved.

  The optical fiber housing member 43 has a structure in which the optical fiber 41 is detachable. When the optical fiber 41 is taken out from the optical fiber housing member 43, a jig having a thin rod shape is inserted into the split portion 45 and the optical fiber 41 is pulled out. In the factory, one side of the double-sided adhesive tape is bonded to the optical fiber housing member 43, the optical fiber 41 is housed in the optical fiber housing member 43, and the back surface of the adhesive tape 46 to be bonded to the wall surface is placed on the sheet Bring it to the construction site. At the time of construction, the optical fiber wiring tool is attached to the wall surface while peeling off the sheet on the back side of the adhesive tape 46 to be bonded to the wall surface.

  Since the optical fiber wiring component and the optical fiber are integrated, the optical fiber wiring is realized in one process. When the optical fiber is coated with an ultraviolet curable resin, the optical fiber becomes transparent. By using a transparent member as the optical fiber housing member, the optical fiber wiring tool becomes transparent, and in-house optical fiber wiring with particularly excellent aesthetics can be realized. In addition, by adopting a structure that allows the optical fiber to be taken out, if an optical fiber malfunction occurs due to some kind of accident, etc., the optical fiber housing member is adhered to the wall surface, and only the optical fiber is taken out and a new optical fiber is obtained. Since it can be exchanged, it has a structure with excellent maintainability.

  In addition, when an optical fiber cord is used instead of the optical fiber 41, it can be implemented in the same manner as when the optical fiber 41 is used. Since the outer diameter of the optical fiber cord is 1.1 mm or 2.0 mm, it is necessary to increase the size of the optical fiber housing member as compared with the case where the optical fiber 41 is used.

  FIG. 5 is a structural explanatory perspective view showing an optical fiber wiring tool according to a fifth embodiment of the present invention. As shown in FIG. 5, tension members 52 are arranged in parallel on both sides along the longitudinal direction of the optical fiber core 51, and the optical fiber core 51 and the tension member 52 are covered with a protective coating 53 to cover indoor light. A fiber 54 is configured. The indoor optical fiber 54 is accommodated in the optical fiber accommodation member 55 along the longitudinal direction. The optical fiber housing member 55 is formed of an elongated rectangular tube, and a split portion 56 for entering and exiting the optical fiber is provided on the side surface of the optical fiber housing member 55 in the axial direction. The split portion 56 is shaped so that the two cantilever portions overlap each other, and once the optical fiber 51 is inserted, it will not jump out of the optical fiber housing member 55 unless the optical fiber 51 is intentionally taken out. . An optical fiber 51 is inserted into and accommodated in the optical fiber accommodation member 55. The optical fiber housing member 55 is bonded to the surface of the adhesive tape 57, and an adhesive is provided on the back surface of the adhesive tape 57.

  That is, when constructing the optical fiber 51 on the wall surface in the house, an optical fiber wiring tool in which the optical fiber accommodating member 55 into which the optical fiber 51 is inserted and accommodated is bonded to the surface of the adhesive tape 57 and integrated is used. 57 Adhere the adhesive on the back to the wall. Therefore, the wiring of the optical fiber 51 to the wall surface can be realized in one process, and the construction efficiency is improved.

  The optical fiber housing member 55 has a structure in which the optical fiber 51 can be attached and detached. In the surface where the adhesive tape 57 of the optical fiber housing member 55 is not adhered, the split portion 56 is formed. When the indoor optical fiber 54 is accommodated in the optical fiber accommodation member 55, the split portion 56 is provided on the short side in the cross section of the optical fiber accommodation member 55 for the purpose of facilitating insertion and removal of the indoor optical fiber 54. When the indoor optical fiber 54 is taken out from the optical fiber housing member 55, the indoor optical fiber 54 is pulled out by manually pushing out from the facing side of the surface where the split portion 56 of the optical fiber housing member 55 is located. In a factory beforehand, one side of a double-sided adhesive tape is bonded to an optical fiber housing member to form an optical fiber wiring device in which the optical fiber is housed in the optical fiber housing member, and a sheet is placed on the adhesive layer side of the double-sided adhesive tape to be adhered to the wall surface Bring it to the construction site with At the time of construction, the optical fiber wiring tool is attached to the wall surface while peeling off the sheet on the adhesive layer side of the double-sided adhesive tape that adheres to the wall surface.

  Since the optical fiber wiring component and the optical fiber are integrated, the optical fiber wiring is realized in one process. By adopting a structure that allows the optical fiber to be taken out, if an optical fiber malfunction occurs due to some kind of accident, take out only the optical fiber and replace it with a new optical fiber with the optical fiber housing member adhered to the wall surface. Therefore, the structure is excellent in maintainability.

  Note that when an optical fiber cord is used instead of the optical fiber 51, it can be carried out in the same manner as when the optical fiber 51 is used. When the drop optical fiber is used, the support wire is drawn into the house in a separated state, and therefore, the configuration is the same as that using the indoor optical fiber.

  FIG. 6 is a front view for explaining the configuration of an optical fiber wiring tool according to a sixth embodiment of the present invention. As shown in FIG. 6, the optical fiber 61 provided with a protective coating is adhered to the surface of the adhesive tape 62 along the longitudinal direction, and an adhesive is provided on the back surface of the adhesive tape 62. A bent portion (a part) in the longitudinal direction of the optical fiber 61 is provided with a cut portion 63 in which a part near both side portions of the adhesive tape 62 is cut so as to sandwich the optical fiber 61, and the width of the adhesive tape 62 is narrow. It is formed.

The vicinity of both side portions of the adhesive tape 62 is cut using a cutting jig during construction. That is, it is constructed while being bonded to the wall surface without being cut, and when a portion to be bent is generated, the vicinity of both side portions of the adhesive tape 62 is cut into a narrow portion using a cutting jig. And it adheres to a wall surface, bending at a narrow part.
That is, when the optical fiber 61 is constructed on the wall surface in the house, an optical fiber wiring tool in which the optical fiber 61 is bonded and integrated on the surface of the adhesive tape 62 is used, and the adhesive on the back surface of the adhesive tape 62 is bonded to the wall surface. Install. In this case, bending work is facilitated so that the narrow part of the adhesive tape 62 provided with the cut part 63 becomes a bent part of, for example, 90 degrees. Therefore, the wiring of the optical fiber 11 to the wall surface can be realized in one process, and the construction efficiency is improved.

  The bent portion facilitates bending by cutting off a part of the double-sided adhesive tape to narrow the width of the optical fiber wiring tool. By narrowing only the portion of the double-sided adhesive tape that is desired to be bent, the straight portion can have a structure with a wide enough width to secure an adhesive area with the wall surface. Since the same optical fiber wiring tool can be used for wiring regardless of the straight portion and the bent portion, the construction efficiency can be improved and the cost of the optical fiber wiring tool can be reduced.

  In addition, when the said optical fiber accommodation member or the said detachable optical fiber accommodation member is used, it can implement similarly to 6th Embodiment. In this case, not only the double-sided adhesive tape portions on both sides of the optical fiber but also the optical fiber housing member or the detachable optical fiber housing member is provided with a cut portion cut by a cutting jig to narrow the width. In addition, when an indoor optical fiber or a drop optical fiber is used, it can be carried out similarly to the sixth embodiment. In this case, since the width is wider than that of the optical fiber alone, the width is reduced by providing a cut-out portion in which the tension member and the protective coating are also cut.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
