Description

  The present invention relates to an optical wiring member used when wiring an optical fiber or an optical fiber cord indoors, and a wiring method using the optical wiring member.

  In recent years, with the development of the information communication society, the introduction of optical fiber communication capable of performing large-capacity data communication has begun to expand. For this reason, the number of subscribers to Fiber to The Home (hereinafter referred to as “Fiber to The Home”), which draws optical fiber in general homes, is increasing, and optical fiber is used indoors. Wiring systems for information communication have come to be used.

  Here, the optical fiber is a structure having only a core and a clad with no coating, and the optical fiber surface is coated with silicone resin, the optical fiber strand is coated with nylon, and the optical fiber is coated with nylon. An optical fiber cord is a core wire or an optical fiber core wire covered with a high-strength fiber and an outer sheath, and a plurality of optical fiber core wires are covered with a sheath called a protective sheath is called an optical fiber cable. Also, the optical fiber and the optical fiber are translucent.

  Conventionally, when an optical fiber cable or optical fiber cord used indoors is wired on a wall surface, a beam, a pillar, or a corner, it cannot be wired as it is, and the optical fiber cable or optical fiber cord is attached to the wall surface or the like. An optical wiring member to be held is required.

As an optical wiring member, there is a staple (see, for example, Patent Document 1) that holds an optical fiber cable or an optical fiber cord in a form of hitting a wall surface. Further, a wire protector (for example, patent document) in which a case for storing an optical fiber cable or an optical fiber cord is arranged and fixed in advance on a wall surface, etc., and the optical fiber cable or the optical fiber cord is stored, and then the case is stored as a lid. 2). These optical wiring members are configured on the assumption that the wiring is coated with a strong material such as an optical fiber cable or an optical fiber cord.

  By the way, according to the recent expansion of FTTH, it is required to reduce the time for indoor wiring work during construction at ordinary homes and to wire indoors with the optical fiber itself.

  However, when the optical fiber is held by a conventional optical wiring member and wired, for example, when the optical fiber is sandwiched between the staples and wired, the optical fiber is thin and has a coating. Since it is not strong, it causes damage to the optical fiber. Furthermore, when an optical fiber strand is inserted into a wire protector and wired, the optical fiber strand is thin, so it cannot be sufficiently held and fixed by the wire protector. Even if it shifts, the optical fiber is damaged. For these reasons, there has been a problem that the optical fiber itself cannot be wired with an optical wiring member.

  For example, even when the optical fiber strand is wired not only with the optical wiring member but also with other reinforcing members, it is necessary to work by placing the optical fiber strand on a wall or the like by a staple. At this time, since the optical fiber is thin, it is difficult to hold it by hand, which makes construction work difficult. Furthermore, when an optical fiber strand is wired using a wire protector, the optical fiber strand moves in the wire protector, making wiring difficult and wiring work difficult. As described above, since wiring work is difficult, there is a problem that it takes construction time.

  Furthermore, hitting a staple on a wall or the like as it is or in combination with another reinforcing member, and installing a wire protector on the wall or the like have a problem that the indoor aesthetics are impaired by these optical wiring members.

  In order to solve the above problems, an object of the present invention is to easily wire an optical fiber itself in a short time without impairing the aesthetic appearance of a wiring place such as a room.

  In order to achieve the above object, the inventors have formed an optical wiring member that accommodates an optical fiber element and performs wiring at an arbitrary place, using a long and narrow rectangular and flexible synthetic resin material. A base, an elongated hollow wiring storage groove into which the optical fiber is inserted along the longitudinal axis, and a wiring along the longitudinal axis that opens from the top surface of the base and penetrates the wiring storage groove. A guide groove portion is formed, and an optical fiber is introduced from the wiring guide groove portion and pushed into the wiring storage groove portion to be inserted and fitted.

  Specifically, in an optical wiring member that accommodates an optical fiber element and performs wiring at an arbitrary place, the cut surface perpendicular to the longitudinal axis of the long shape forms a rectangular shape, and A base made of a synthetic resin material having flexibility, and an elongated hollow shape penetrating the front and rear end surfaces of the base along the longitudinal axis of the base and capable of fitting the optical fiber A wiring guide groove formed along the longitudinal axis, and a wiring guide groove formed through the wiring storage groove formed through the upper surface of the base and extending through the wiring storage groove. Wiring in which the boundary with the guide groove protrudes in a direction opposite to each other through a gap having a constant width along the longitudinal axis, and the gap between the protrusions is narrower than the diameter of the wiring storage groove An insertion front is formed, and between this wiring insertion That it is possible to push the optical fiber to the wiring housing groove portion at a predetermined or more pressure from an optical interconnection member according to claim.

  According to this configuration, when an optical fiber strand is wired in a place such as a room, the optical wiring member is attached to a wiring construction path such as a wall surface by an adhesive means, and then the optical fiber strand is attached from the wiring guide groove. Then, the optical fiber strands may be pushed in, inserted into the wiring storage groove from the wiring insertion opening, and fitted. Therefore, the wiring work can be easily performed in a short time. Also, since the optical wiring member is made of a flexible synthetic resin material, when the optical fiber strand is pushed from the wiring insertion opening, the flexible protrusion at the wiring insertion opening is bent downward and expanded. It is inserted and fitted into the storage groove. At this time, since the optical fiber is only in contact with a flexible synthetic resin material, damage to the optical fiber is applied even if the optical fiber has a small diameter and the coating is not strong. There is no.

  It is desirable that the optical wiring member of the present invention further includes a sheet-like adhesive with release paper that is adhered to the lower surface of the base and the adhesive surface is exposed when the release paper is peeled off.

  According to this configuration, it is only necessary to peel off the release paper of the adhesive material with release paper and attach the optical wiring member to the wiring construction path when wiring the optical fiber, so that the wiring work can be performed more easily and in a short time. Can do.

  In the optical wiring member of the present invention, it is preferable that the wiring guide groove portion has a shape that opens from the upper surface of the base and penetrates the wiring housing groove portion in a V shape.

  According to this configuration, when the wiring guide groove portion is opened from the upper surface of the base and has a shape that penetrates into the wiring housing groove portion in a V shape, the entrance for introducing the optical fiber strand is wide and the V shape is formed from the entrance. Since it is narrow and reaches the wiring insertion opening, it is easy to introduce the optical fiber. That is, since the optical fiber is thin, it can be easily attached in a short time even when it is difficult to grasp by hand.

  The optical wiring member of the present invention has a notch penetrating the base up and down on both sides or one side in the width direction perpendicular to the longitudinal axis of the base and outside the wiring guide groove. It is desirable to provide at least one or more along the longitudinal axis.

  According to this configuration, if, for example, a plurality of the notches are formed in the optical wiring member, the optical wiring member can be easily bent at an arbitrary angle in the width direction. Therefore, even if the wiring construction path is curved in the middle, the optical wiring member can be easily bent in accordance with the curvature, so that the wiring work can be easily performed in a short time. In addition, if an optical wiring member without a notch is bent in the width direction at a right angle or an acute angle with a small bending radius that is not less than the allowable bending radius of the optical fiber, a distortion such as a crack may be generated or torn. However, since the distortion and tearing can be prevented by making the notch, the life of the optical wiring member can be extended.

  The optical wiring member of the present invention has a second notch cut in a V-shape on both sides outside the wiring guide groove portion of the base, which is cut from the upper surface of the base to a middle position toward the lower surface. It is desirable that at least one is provided along the longitudinal axis.

  According to this configuration, the optical wiring member can be bent in the thickness direction so as not to be distorted or damaged in the base, so that the optical wiring member can also be disposed at the entrance and exit corners of a room or the like.

  In the optical wiring member of the present invention, it is preferable that reinforcing members are provided on both sides of the wiring housing groove portion of the base along the wiring housing groove portion.

  According to this configuration, the tensile strength of the base of the optical wiring member can be increased, and the force applied to the base during wiring construction can be received, so that damage to the base can be reduced.

  The optical wiring member of the present invention has a size in which the plurality of optical fiber strands can be inserted in the width direction perpendicular to the longitudinal axis into the elongated cavity along the longitudinal axis of the base, with the wiring housing groove portion It is desirable that the recesses are communicated with each other.

  According to this configuration, the number of optical fiber strands housed in the optical wiring member can be increased by providing the recess in the wiring housing groove. Further, even if the cross section is not round as in the case of an optical fiber, a flat optical fiber cord can be stored.

  In the optical wiring member of the present invention, it is preferable that the base is colorless and transparent.

  According to this configuration, since the base is colorless and transparent, the color, shape, and pattern of the mounting surface can be transmitted to the mounting surface such as the wall surface. Since the optical fiber housed in the optical wiring member is also colorless and transparent, the color, shape and pattern of the mounting surface can be similarly transmitted. For this reason, the appearance of the mounting surface is not impaired.

  The optical wiring member according to the present invention is configured to store any of a single mode type optical fiber, a hole assist fiber, a plastic optical fiber, an optical fiber cord, a LAN cable, and a copper wire instead of the optical fiber. It is desirable to accommodate in the groove.

  Specifically, in the wiring method using the optical wiring member for wiring the optical fiber using the optical wiring member according to any one of claims 1 to 9, both end surfaces and parallel to the both end surfaces are provided. Light whose cross section forms a crescent-shaped column, the outer arc surface of the crescent moon is an entrance corner installation surface installed at the entrance corner, and the inner arc surface of the crescent moon is disposed on the optical wiring member A corner spacer made of a flexible synthetic resin material having the same color as the optical wiring member is used as the wiring member disposition surface. Arranged at the corners, both end faces and the cross section parallel to the both end faces form an L-shaped column, and the L-shaped inner side is a right-angled surface and the outer side is a convex arc surface. And an optical wiring member disposition surface on which the convex arc surface is disposed. And a protruding corner spacer formed of a flexible synthetic resin material of the same color as the optical wiring member, if there is a protruding corner of the optical fiber strand wiring construction route, A wiring method using an optical wiring member, characterized in that the optical fiber element wire is disposed on the optical wiring member disposition surface of either or both of the entrance corner spacer and the exit corner spacer disposed. is there.

  According to this method, the optical wiring member is bent and arranged while securing a predetermined bending radius of the optical fiber by arranging and fixing the entrance corner spacer at the entrance corner of the room or the like and the exit corner spacer at the exit corner. can do. In addition, the entrance corner spacer and the exit corner spacer are made of the same colorless and transparent synthetic resin material as the optical wiring member, so the color and shape of the mounting surface with respect to the mounting surface of the entrance corner and the exit corner The pattern can be transmitted. For this reason, the appearance of the mounting surface is not impaired.

  In the wiring method using the optical wiring member according to the present invention, the light having a width of a groove in which the base of the optical wiring member is fitted to the optical wiring member-arranged surfaces of both the entrance corner spacer and the exit corner spacer. It is desirable to provide a wiring member fitting groove.

  According to this method, since the optical wiring member is held in the optical wiring member fitting groove, it is possible to prevent the optical wiring member from dropping off when the optical wiring member is disposed in the corner.

  According to the present invention, there are provided an optical wiring member and an optical wiring member using the optical wiring member capable of easily wiring an optical fiber itself without damaging the aesthetic appearance of a wiring place such as a room. be able to.

  Embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below are examples of the present invention, and the present invention is not limited to the following embodiments. In the present specification and drawings, the same reference numerals denote the same components.

  FIG. 1 is a perspective view showing a configuration of an optical wiring member according to an embodiment of the present invention, and FIG. 2 is a cross-section when the optical wiring member shown in FIG. 1 is cut along a plane perpendicular to the longitudinal axis of the optical wiring member. FIG. However, it is assumed that the optical wiring member 10 shown in FIG. 1 is a portion obtained by cutting and extracting one section of the long optical wiring member 10.

  The optical wiring member 10 of the present embodiment is formed of a long, rectangular bar-shaped synthetic resin material having a rectangular shape in which a cut surface orthogonal to the longitudinal axis of the rectangular bar is a horizontally long rectangle, and is colorless and transparent. And a wiring storage groove portion 12 having a substantially cylindrical cavity through which optical fiber strands (not shown) are inserted along the longitudinal axis of the base 11 and penetrate the front and rear end surfaces of the base 11, A wiring guide groove 13 formed by a V-shaped groove formed along the longitudinal axis and communicating with the wiring housing groove 12 from the upper surface of the base 11 in a V shape, and a seal bonded to the lower surface of the base 11 It is comprised from the adhesive material 14 with a release paper.

  The wiring housing groove portion 12 and the wiring guide groove portion 13 have a keyhole shape in which the cross-sectional shape communicates the circular shape and the V shape, and the boundary portion between the circular shape and the V shape is constant along the longitudinal axis. A pair of projecting portions 15a and 15b project in a state of facing each other through a gap of width. A gap between the protrusions 15a and 15b is a wiring insertion opening 15 into which an optical fiber is inserted.

  As shown in FIG. 2, the distance L1 between the wiring insertion openings 15 is shorter than the diameter L2 of the wiring housing groove 12, and the optical fiber strand 1 is connected as shown in FIGS. 3 (a) to 3 (b). When introduced from the wiring guide groove 13 and inserted into and fitted into the wiring housing groove 12, the optical fiber 1 is not easily detached from the wiring housing groove 12.

  In other words, as shown in FIG. 3A, the wiring insertion opening 15 introduces the optical fiber 1 from the wiring guide groove 13 in a state where the adhesive material 14 with release paper is fixed to, for example, a horizontal floor surface. At that time, the optical fiber 1 is placed on the protrusions 15a and 15b and does not enter the wiring housing groove 12. When the placed optical fiber 1 is pressed downward, the protrusions 15a and 15b bend toward the wiring housing groove 12 and the optical fiber 1 is wired as shown in FIG. It is formed so as to enter and fit into the storage groove 12.

  The synthetic resin material of the base 11 includes thermoplastic resins such as polyvinyl chloride (PVC), acrylic resin (PMMA), polycarbonate (PC), and fluororesin (PTEF) having a hardness of 89 to 96 degrees, polyethylene ( A plastic such as PE) or polypropylene (PP) is used.

  The optical wiring member 10 having such a configuration has a plurality of types of long and short lengths, but in actual construction, if there is no length suitable for the wiring location of the optical fiber, it is cut and used. Here, for example, in the room 30 shown in FIG. 4, as shown by the arrow P <b> 1, the wall surface 31 b joined at a right angle to the wall surface 31 a from the drawing position through which the optical fiber is drawn from the upper back surface side of the wall surface 31 a. A case is assumed in which the optical fiber is wired up to the lower rosette 32. However, it is assumed that the convex column 33 is passed in the middle of the wiring.

  When this wiring is performed, an in-corner spacer denoted by reference numeral 41, an exit-corner spacer denoted by reference numeral 42, and a curved optical wiring member denoted by reference numeral 10-1 are required. This is because the wall 31a and the wall 31b, the column 33, and the column 33 and the wall 31b are attached by passing through the corners, and when the linear optical wiring member 10 is moved horizontally from the horizontal state. On the other hand, if the linear optical wiring member 10 is bent at a right angle or an acute angle with an extremely small bending radius when it is bent and attached in a vertical state, it is cracked or broken. As a further reason, even if the straight optical wiring member 10 is abutted at a corner, the optical fiber strand must ensure a predetermined bending radius, and a right angle with a minimum diameter or a predetermined bending radius. This is because the wiring cannot be bent at an acute angle.

First, the configuration of the optical wiring member 10-1 will be described with reference to the plan view of the optical wiring member 10-1 shown in FIG.
The optical wiring member 10-1 has a notch 21 penetrating the upper and lower surfaces in a V shape on both sides (or only one side) outside the wiring guide groove 13 of the base 11, and the longitudinal axis of the base 11. Are provided at predetermined intervals. A shown in the optical wiring member 10-1 is an interval between the notches 21 (notch interval), B is a width of the notch 21 (notch width), C is a depth of the notch 21 (notch depth), D Represents the angle of the notch 21 (notch angle). W represents the width of the dimension orthogonal to the longitudinal axis of the optical wiring member 10.

  By providing such a notch 21, the optical wiring member 10-1 can be bent at an arbitrary angle in the width W direction as shown in FIG. However, the symbol R shown in FIG. 6 indicates the allowable bending radius of the base 11. The allowable bending radius R, the notch interval A, the notch width B, and the notch depth C of the optical wiring member 10-1 have the relationship of the following equation (1).

  (Notch width B / Notch interval A) = 1- (Notch depth C / Allowable bending radius R) (1)

  For example, when the allowable bending radius R = 3 mm and the notch depth C = 2 mm, the notch interval A = 18.9 mm and the notch width B = 6.3 mm are obtained from the above equation (1). If the angle D = 18 degrees, the number of the notches 21 is five, and it can be bent to 90 degrees.

  More specifically, as shown in FIG. 6, the optical wiring member 10-1 when the optical wiring member 10-1 is bent is deformed as shown in FIG. The allowable bending radius R at this time can be calculated from the arc A and the arc B of the trapezoidal portion of the base 11 between the notch 21 and the notch 21.

That is, when the angle D is used, the outermost arc length A can be obtained from the following equation (2).
A = 2π × (D / 360) × R (2)

Similarly, the length B of the inner circumference arc can be obtained from the following equation (3) when the angle D is used.
B = 2π × (D / 360) × (RC) (3)

When the angle D is removed from the above equations (2) and (3), the following equation (4) is obtained.
A / R = B × (RC) (4)
When this equation (4) is modified, B / A = 1− (C / R) and the above equation (1) is obtained.

  Next, the entrance corner spacer 41 and the exit corner spacer 42 will be described. As described above, the reason for using the entrance corner spacer 41 and the exit corner spacer 42 is that the optical fiber inserted into the optical wiring member 10 is less than the allowable bending radius of the optical fiber in order to prevent breakage. The wiring cannot be formed by bending at a right angle or an acute angle with a small-diameter bending radius (hereinafter simply referred to as a small-diameter bending radius), and a predetermined bending radius must be ensured. For example, it is necessary to secure a bending radius of 5 mm or more for a hole assist fiber as an optical fiber, and a bending radius of 15 mm or more for an SM (single mode) type optical fiber.

  For this reason, for example, as shown in FIG. 8A, when a convex portion 45 such as a pillar is fixed to a flat surface 44 such as a wall, the surfaces of the flat surface 44 and the convex portion 45 are attached to the inside. A corner spacer 41 is arranged and fixed in the corner. Further, as shown in (b), a protruding corner spacer 42 is arranged and fixed at the protruding corner which is the protruding corner of the convex portion 45. By these arrangement and fixation, as shown in (c), it becomes possible to arrange the optical wiring member 10 while ensuring a predetermined bending radius or more.

  The entrance corner spacer 41 and the exit corner spacer 42 are made of the same transparent and flexible synthetic resin material as the base 11.

  As shown in the perspective view of FIG. 9 (a), the corner spacer 41 has a crescent-shaped column at both end faces and a cross section parallel to the both end faces, and a crescent-shaped outer peripheral arc surface is installed at the corner. The inner corner arc surface 41a is an optical wiring member arrangement surface 41b on which the optical wiring member 10 is arranged.

  Further, the corner spacer 41 can be flexibly bent or compressed, and a force is applied from the upper side of the corner installation surface 41a as indicated by an arrow F1 with the corner spacer 41 placed on the floor surface. Then, as shown in FIG. 9B, the corner spacer 41 shrinks in the vertical direction, and the distance G1 between the upper and lower sides of the optical wiring member placement surface 41b becomes shorter. This can be bent or compressed until the distance G1 becomes 0 mm, and when the force F1 is released, the original shape is naturally restored by the repulsive force of the corner spacer 41 at the time of opening. .

  As shown in the perspective view of FIG. 10A, the protruding corner spacer 42 has L-shaped columnar cross sections parallel to both end surfaces and the both end surfaces, and the L-shaped inner side is a right-angled surface and the outer side is convex. The right-angled surface is a protruding corner installation surface 42 a installed at the protruding corner, and the convex arc surface is an optical wiring member arrangement surface 42 b on which the optical wiring member 10 is arranged.

  Further, the protruding corner spacer 42 can be flexibly bent or compressed, and a force is applied from the upper side of the protruding corner installation surface 42a as indicated by an arrow F2 with the protruding corner spacer 42 placed on the floor surface. Then, as shown in FIG. 10B, the protruding corner spacer 42 is contracted in the vertical direction, and the distance G2 between the upper and lower sides of the optical wiring member disposition surface 42b is shortened. This can be bent or compressed until the distance G2 becomes 0 mm, and when the force F2 is released, the original shape is naturally restored by the repulsive force of the protruding corner spacer 42 at the time of opening. .

  Further, it is possible to easily change the bending radius of the optical wiring member 10 by changing the shape and size of the entrance corner spacer 41 and the exit corner spacer 42 or by taking a corner.

  Next, a procedure for wiring an optical fiber strand in the room 30 as shown in FIG. 4 using the optical wiring member 10, the entrance corner spacer 41, and the exit corner spacer 42 will be described.

  First, the wiring construction route from the drawing position P1 of the optical fiber to the rosette 32 is determined, and the entrance corner spacer 41 and the exit corner spacer 42 are fixed to necessary portions on the wiring construction route. In this case, it is fixed to the entrance corner of the wall surfaces 31 a and 31 b, the entrance corner of the wall surface 31 b and the column 33, and the exit corner of the column 33. After this fixing, the optical wiring member 10 is cut to a length suitable for the wiring construction route.

  Further, if there is a bent portion where the optical wiring member 10 must be bent in the width W direction in the wiring construction path, the optical wiring member 10 is provided with a plurality of notches 21, and the optical wiring member 10 provided with the notches 21. -1 is bent in the width W direction so as to match the bending of the wiring construction route. However, a plurality of types of optical wiring members 10-1 provided with a plurality of notches 21 in advance may be prepared and used.

  The prepared optical wiring members 10 and 10-1 are stuck and fixed at predetermined positions in the wiring construction route while peeling the release paper of the adhesive material 14 with release paper in order. In this case, it is also possible to attach and fix one optical wiring member 10 from the drawing position P1 to one end of the curved optical wiring member 10-1. In this case, the optical wiring member 10-1 A short optical wiring member 10 is fixed from the other end to the rosette 32.

  After the optical wiring members 10 and 10-1 are arranged and fixed, as shown by an arrow Y1 in FIG. 11, the optical fiber element 1 is pushed in while being introduced from the wiring guide groove portion 13, and as shown in FIG. It only has to be fitted and stored.

  As described above, according to the present embodiment, the optical wiring member 10 that accommodates the optical fiber strand and performs wiring at an arbitrary place has a long cut surface that is orthogonal to the longitudinal axis of the long shape. And a base 11 made of a flexible synthetic resin material, and an elongated hollow and optical fiber strand penetrating the base 11 along the longitudinal axis to the front and rear end faces of the base 11 And a wiring guide groove portion 13 formed along the longitudinal axis, the groove being opened from the upper surface of the base 11 and penetrating into the wiring storage groove portion 12. .

  Further, the boundary portion between the wiring housing groove portion 12 and the wiring guide groove portion 13 is formed with protrusion portions 15a and 15b protruding in opposite directions through a gap having a constant width along the longitudinal axis. A gap interval L1 between the wires 15b is formed as a wiring insertion opening 15 whose dimension is shorter than the diameter L2 of the wiring storage groove 12, and an optical fiber element is inserted into the wiring storage groove 12 from the wiring insertion hole 15 with a predetermined pressing force or more. It is possible to push into.

  When the optical fiber member 10 is wired to a place such as the room 30 using the optical wiring member 10 having this configuration, the optical wiring member 10 is attached to a wiring construction path such as the wall surfaces 31a and 31b by an adhesive means, for example. Thereafter, the optical fiber element wire is introduced from the wiring guide groove portion 13, and the optical fiber element wire is further pushed in and inserted into the wiring accommodating groove portion 12 from the wiring insertion opening 15, so that the wiring work can be easily performed in a short time. Can be done.

  Further, since the optical wiring member 10 is made of a flexible synthetic resin material, the flexible protrusions 15a and 15b of the wiring insertion opening 15 are formed when the optical fiber is pushed from the wiring insertion opening 15. It expands while bending downward, and is inserted and fitted into the wiring housing groove 12. At this time, since the optical fiber is only in contact with a flexible synthetic resin material, damage to the optical fiber is applied even if the optical fiber has a small diameter and the coating is not strong. There is no.

  Further, in a state where the optical fiber strand is fitted in the wiring housing groove portion 12, the optical fiber strand is in close contact with the synthetic resin material having a large resistance and is pressed down by the projections 15a and 15b. The wire can be held and fixed sufficiently. As a result, the optical fiber is not displaced and damaged in the wiring housing groove portion 12 and is not easily detached from the optical wiring member 10 to be damaged or broken.

  Further, when a sheet-like adhesive 14 with release paper is provided on the lower surface of the base 11 of the optical wiring member 10 so that the adhesive surface is exposed when the release paper is peeled off, the adhesive with release paper is used when wiring the optical fiber. Since the release paper of the material 14 may be peeled off and attached to the wiring construction route, the wiring construction can be performed more easily and in a short time.

  Further, when the wiring guide groove portion 13 is opened from the upper surface of the base 11 and has a shape that penetrates into the wiring storage groove portion 12 in a V shape, the entrance for introducing the optical fiber is wide and narrow from the entrance to the V shape. Thus, since it reaches the wiring insertion opening 15, it is easy to introduce the optical fiber. That is, since the optical fiber is thin, it can be easily attached in a short time even when it is difficult to grasp by hand.

  Further, like the optical wiring member 10-1, one or a plurality of notches 21 are formed so that the optical wiring member 10-1 can be easily bent at an arbitrary angle in the width W direction. As a result, the optical wiring member 10-1 can be easily bent at an angle required for wiring such as a right angle with a small bending radius in the middle.

  Therefore, even if the wiring construction path is curved in the middle, the optical wiring member 10-1 can be easily bent according to the curve, so that the wiring work can be easily performed in a short time. Further, if the optical wiring member 10 without the notch 21 is bent at a right angle or an acute angle with a small bending radius in the width W direction, a crack or the like may be distorted or torn. It is possible to prevent tearing. For this reason, the lifetime of the optical wiring member 10 can also be extended.

  Moreover, since the synthetic resin material of the optical wiring member 10 is colorless and transparent, the color, shape, and pattern of the mounting surface can be transmitted to the mounting surface such as the wall surface 31a. Since the optical fiber element housed in the optical wiring member 10 is also colorless and transparent, the color, shape and pattern of the mounting surface can be similarly transmitted. For this reason, the appearance of the mounting surface is not impaired.

  In addition to the method of inserting the optical fiber after the optical wiring member 10 is fixed, the optical fiber 1 is stored in the wiring storage groove 12 of the optical wiring member 10 in advance. The optical wiring member 10 in which 1 is accommodated may be affixed and fixed to the wiring construction path. In the case of this wiring method, it does not take time to store the optical fiber strands in the wiring storage groove 12, making the wiring work easier and shortening the installation time.

  In addition, when there is an entrance corner and an exit corner where the wall surfaces 31a and 31b are joined at right angles in the middle of the wiring construction path, or an entrance corner and an exit corner where the column 33 etc. protrudes in a convex shape on the wall surfaces 31a and 31b, Wiring work was performed using the entrance corner spacer 41 and the exit corner spacer 42 made of the same colorless and transparent synthetic resin material as the optical wiring member 10.

  That is, both end faces and a cross section parallel to the both end faces form a crescent-shaped columnar shape, and a crescent-shaped outer peripheral arc surface is installed at the inner corner, and an inner-corner installation surface 41a, and the inner peripheral arc surface is an optical wiring A corner spacer 41 having an optical wiring member placement surface 41b on which the member 10 is placed is placed in the corner.

  In addition, both end faces and a cross section parallel to the both end faces form an L-shaped column, and the L-shaped inner side is a right-angled surface, the outer side is a convex arc surface, and the right-angled surface is installed at the outer corner. An exit corner spacer 42 having a surface 42a and an optical wiring member disposition surface 42b on which the convex arc surface is disposed is disposed at the exit corner.

  In general, since an optical fiber cannot be wired at a right angle or an acute angle with a small bending radius to prevent breakage, a predetermined bending radius must be ensured. For this reason, even if an optical fiber strand is communicated with the optical wiring member 10, it cannot be wired as it is in the entrance corner or the exit corner.

  However, by arranging and fixing the entrance corner spacer 41 and the exit corner spacer 42 as described above, the optical wiring member 10 can be bent and disposed while ensuring a predetermined bending radius of the optical fiber.

  Further, since the entrance corner spacer 41 and the exit corner spacer 42 are formed of the same colorless and transparent synthetic resin material as that of the optical wiring member 10, the attachment surface of the entrance corner and the exit corner are not attached. Color, shape and pattern can be transmitted. For this reason, the appearance of the mounting surface is not impaired.

  Further, as shown in FIG. 13A, an optical wiring member fitting groove which is a groove having a width in which the base 11 of the optical wiring member 10 is fitted to the optical wiring member disposing surface 41b of the corner spacer 41-1. 41c may be provided. In the case of this configuration, since the optical wiring member 10 is held by the optical wiring member fitting groove 41c, it is possible to prevent the optical wiring member 10 from falling off when the optical wiring member 10 is disposed at the corner.

  Further, as shown in FIG. 13B, an optical wiring member fitting groove which is a groove having a width in which the base 11 of the optical wiring member 10 is fitted to the optical wiring member arranging surface 42b of the protruding corner spacer 42-1. 42c may be provided. In the case of this configuration, since the optical wiring member 10 is held by the optical wiring member fitting groove 42c, it is possible to prevent the optical wiring member 10 from falling off when the optical wiring member 10 is disposed at the protruding corner.

  In addition to the above, as shown in FIG. 14, tension members 51a and 51b as reinforcing members are provided along the wiring housing groove 12 on both sides of the wiring housing groove 12 of the base 11 of the optical wiring member 10-2. May be.

  In the case of the optical wiring member 10-2 having this configuration, the tensile strength of the base 11 can be increased, and the force applied to the base 11 during wiring construction can be received, so that damage to the base 11 can be reduced. .

  Next, instead of the above-described wiring housing groove portion 12 having a substantially circular cross section, a groove shape wiring housing groove portion 12-1 shown in FIG. 15 may be formed. The wiring storage groove 12-1 has a trapezoidal cross section of an elongated cavity along the longitudinal axis of the base 11, and a plurality of optical fibers in the width W direction of the base 11 from one corner portion of the trapezoid. A recess 12a having a size capable of inserting a strand is formed.

  Thus, by providing the recessed part 12a in the wiring accommodation groove part 12-1, the number of the optical fiber strands accommodated in the optical wiring member 10-3 can be increased. Further, even if the cross section is not round as in the case of an optical fiber, a flat optical fiber cord can be stored.

  Next, as shown in FIG. 16, on both side portions of the wiring guide groove 13 in the base 11 of the optical wiring member 10-4, cut in a V shape in a thickness T direction opening from the upper surface toward the lower surface. One or more notches 53 may be formed on the longitudinal axis of the base 11 at predetermined intervals.

  Since the optical wiring member 10-4 having this configuration can be bent in the thickness T direction so that the base 11 is not distorted or damaged, the optical wiring member 10-4 can also be disposed at the entrance corner and the exit corner. Moreover, the bending radius R can be calculated | required by the same formula (1) as the optical wiring member 10-1 in which the notch 21 demonstrated above was formed. That is, it can be set similarly to the optical wiring member 10-1 having the notch 21 in the width W direction.

  The above description is based on the assumption that the optical fiber strand is stored in the wiring storage groove portion 12, but instead of the optical fiber strand, an SM-type optical fiber strand, a hole assist fiber, a plastic optical fiber, an optical fiber It is also possible to accommodate fiber cords, LAN cables, copper wires and the like.
