Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, in order to route a communication line at a high place, a cable is stretched between structures such as utility poles. And a holding component is attached to the wire stretched between the utility poles, and the communication line is held by the wire by passing the communication line through the holding component. Here, for the housing case, for example, it is possible to hold it by taking out a steel wire from the communication line and attaching the steel wire to the housing case. However, with such means, there is a concern that the housing case may move due to the wind and problems such as the communication line being twisted may occur.

[0005] An object of the present invention is to suppress the occurrence of problems in the communication line at the connection portion of the communication line.

Means for Solving the Problems

[0006] According to the present invention, there is provided a holding structure for holding a connection portion of a communication line around a wire, the holding structure including: a mounting member; a housing case for housing the connection portion of the communication line; and a fixing member provided on the mounting member, wherein the mounting member is configured to be able to dispose the connection portion of the communication line, the housing case is attached to the mounting member, the fixing member is configured to be able to fix the mounting member to the wire, and the fixing angle of the mounting member to the wire is configured to be changeable.

[0007] According to the present invention, in addition to the fixing member being configured to be able to fix the mounting member to the wire, the fixing member is configured to be able to change the fixing angle of the mounting member to the wire. Therefore, the arrangement angle of the housing case can be changed to an angle with less wind resistance, and it is possible to suppress the housing case from moving due to the influence of the wind. As a result, it is possible to suppress the occurrence of problems in the communication line.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The various characteristic matters shown in the following embodiments can be combined with each other. Also, an invention can be established independently for each characteristic matter.

[0010] 1. Description of the overall configuration of the embodiment As shown in FIG. 1, the holding structure 100 according to the embodiment is fixed to, for example, a wire Wr stretched on a structure 20. The wire Wr has a function of holding the communication lines 31 and 32 to route them in the air. The holding structure 100 can be utilized, for example, when performing an opening work for connecting an optical fiber line to a terminal device 22 provided in a building 21. Note that the terminal device 22 is a device installed on the terminal side of the drawing-in destination of the optical fiber line and has, for example, a function of converting an optical signal into an electrical signal. In the opening work, an optical fiber line 31a (see FIG. 2) is taken out from the communication line 31 on the wire Wr side, and this optical fiber line 31a is connected to the optical fiber line 32a of the communication line 32 on the building 21 side (terminal device 22 side). Since it is not preferable that the connecting portion 33 between the optical fiber line 31a and the optical fiber line 32a is exposed and the connecting portion 33 is in a non-fixed state, the holding structure 100 houses and protects the connecting portion 33, and the connecting portion 33 is also prevented from moving and being agitated by wind or the like because the holding structure 100 is fixed to the wire Wr. The above-described connecting portion 33 can be configured by, for example, a connector that connects optical fiber lines to each other.

[0011] Note that, as shown in FIGS. 1 and 2, the communication lines 31 and 32 include optical fiber lines 31a and 32a and steel wires 31b and 32b. The steel wires 31b and 32b are core materials for ensuring the strength of the communication lines 31 and 32. In the communication lines 31 and 32, a plurality of optical fiber lines and steel wires are bundled, and the outer peripheral portions of the optical fiber lines are covered and protected by, for example, resin members or the like.

[0012] Also, in FIG. 1, a part of the communication line 32 is provided along the wire Wr, but the other part of the communication line 32 is redirected, for example, by passing through a hanging member 23 fixed to the wire Wr and heads toward the terminal device 22 of the building 21. In addition, the structure 20 shown in FIG. 1 is a utility pole in the embodiment, but it is not limited to a utility pole and may have other structures. Similarly, the building 21 is a single-family house in the embodiment, but it is not limited to this and may be, for example, an apartment building or the like, or a building. Further, the wire Wr is provided with, for example, a hanger member (not shown), and by passing the communication lines 31 and 32 through the hanger member, the communication lines 31 and 32 can be held along the wire Wr.

[0013] 2. Detailed Configuration Explanation of the Holding Structure 100 The holding structure 100 includes a mounting member 1, a housing case 2 that houses the connection portion 33 of the communication lines 31 and 32, a fixing member 3 provided on the mounting member 1, and a connecting member 4, and has a function of holding the connection portion 33 of the communication lines 31 and 32 around the wire Wr.

[0014] 2-1. Mounting Member 1 As shown in FIGS. 4 to 7, the mounting member 1 is configured in a plate shape. Specifically, the mounting member 1 is a plate-shaped member made of metal and has an upper surface and a lower surface. In addition, the mounting member 1 is configured to be able to dispose the connection portion 33 of the communication lines 31 and 32. In the embodiment, by fixing the housing case 2 that houses the connection portion 33 to the mounting member 1, the connection portion 33 is disposed on the upper surface of the mounting member 1.

[0015] The connection portion 33 of the communication lines 31 and 32 is disposed above the upper surface of the mounting member 1. Specifically, the housing case 2 is disposed above the upper surface of the mounting member 1, and the connection portion 33 is housed in the housing case 2. The wire Wr is disposed below the lower surface of the mounting member 1. Thus, in the holding structure 100 according to the embodiment, since the wire Wr and the connection portion 33 (housing case 2) are independently disposed with the upper and lower sides of the mounting member 1 as a boundary, it is difficult for the operator's hand to interfere with the wire Wr when performing work on the connection portion 33, and the workability is improved.

[0016] The mounting member 1 can be made of, for example, stainless steel. Note that the material constituting the mounting member 1 is not limited to this, and it may be made of other metal materials. Since the mounting member 1 is arranged outdoors, it is preferable that the surface of the mounting member 1 is subjected to rust prevention treatment. Also, the mounting member 1 may be made of resin or carbon material, but it is preferably made of metal. In the embodiment, the mounting member 1 is described as being solid, but it may be hollow. Note that the mounting member 1, the fixing member 3, and the connecting member 4 described later may be installed at another location and reused after use.

[0017] The mounting member 1 is to be arranged in an environment such as outdoors where it is easily exposed to the wind. For this reason, as shown in FIG. 3, when the mounting member 1 is fixed to the wire Wr, it forms an angle θ with respect to the horizontal plane. Specifically, the angle θ is, for example, 20, 25, 30, 35, 40, 45, 50, 55, 60 degrees, and it may be within the range between any two of the values exemplified here. For example, when the mounting member 1 is fixed to the wire Wr, it forms an angle of 20 degrees or more and 60 degrees or less with respect to the horizontal plane. Thereby, it is possible to suppress the holding structure 100 from being exposed to the wind and shifting in position. Also, since the angle θ avoids the range of 0 degrees or more and less than 20 degrees, it is easier to avoid dust, snow, etc. from accumulating on the upper surface of the holding structure 100 and birds and beasts from staying.

[0018] The mounting member 1 shown in FIGS. 5 to 7 has a main body portion 1a and a pair of protruding portions 1b.

[0019] 2-1-1. Main body portion 1a The main body portion 1a is a portion where the housing case 2, the fixing member 3, and the connecting member 4 are arranged, and is configured in a plate shape.

[0020] The main body portion 1a has a first plate-shaped portion 1a1 and a pair of second plate-shaped portions 1a2 connected to the first plate-shaped portion 1a1. As shown in FIGS. 5 to 7, a fixing member 3 is provided on the first plate-shaped portion 1a1. A pair of second plate-shaped portions 1a2 are connected to the first plate-shaped portion 1a1. Further, on the first plate-shaped portion 1a1, hole portions 1a11 (two in the embodiment) through which steel wires 31b, 32b installed in communication lines 31, 32 pass and hole portions (four in the embodiment) through which the fixing member 3 passes are formed. The housing case 2 is arranged on the pair of second plate-shaped portions 1a2. In the embodiment, the shapes of the pair of second plate-shaped portions 1a2 may be the same or different. Further, as shown in FIG. 7, the portions where the pair of second plate-shaped portions 1a2 are connected to the first plate-shaped portion 1a1 are arranged symmetrically with respect to the center line C of the width of the first plate-shaped portion 1a1 in the stretching direction Dr1 of the wire Wr, but it is not limited thereto and may be asymmetric.

[0021] As shown in FIG. 7, a gap 1c (open portion) is formed between one second plate-shaped portion 1a2 and the other second plate-shaped portion 1a2. By forming the gap 1c in the mounting member 1, the material cost is suppressed and the weight of the holding structure 100 is suppressed.

[0022] The total width of the main body portion 1a in the stretching direction Dr1 of the wire Wr is defined as the lateral width W1 of the main body portion 1a. Also, the total width of the main body portion 1a in the direction Dr2 orthogonal to the stretching direction Dr1 of the wire Wr is defined as the longitudinal width L1 of the main body portion 1a. The width W2 of the gap 1c in the stretching direction Dr1 of the wire Wr is preferably 50% or more of the lateral width W1 of the main body portion 1a. Further, specifically, for example, the width W2 is 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or more of the lateral width W1, and may be within the range between any two of the values exemplified here. The width L2 of the gap 1c in the direction Dr2 orthogonal to the stretching direction Dr1 of the wire Wr is preferably 50% or more of the longitudinal width L1 of the main body portion 1a. Further, specifically, for example, the width L2 is 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or more of the longitudinal width L1, and may be within the range between any two of the values exemplified here.

[0023] As shown in FIG. 7, each second plate-shaped portion 1a2 is formed with a hole portion 1a21. The hole portion 1a21 is capable of inserting a connecting member 4 described later.

[0024] 2-1-2. Protrusion 1b As shown in FIGS. 5 to 7, the pair of protrusions 1b are provided so as to protrude from the edge of the main body portion 1a (the second plate-shaped portion 1a2 in the embodiment). The protrusion 1b is also configured in a plate shape similar to the main body portion 1a. One of the protrusions 1b shown in FIG. 5 is attached to the insertion port 2c (see FIG. 4) of the communication line 32 provided in the housing case 2. Similarly, the other protrusion 1b is attached to the insertion port 2c (not shown) of the communication line 31 provided in the housing case 2.

[0025] As shown in FIG. 2, the protrusion 1b has a function of suppressing the movement and breakage of the front portion 40 of the optical fiber lines 31a and 32a of the communication lines 31 and 32 that is inserted into the housing case 2. Specifically, for example, a tape having adhesiveness (not shown) is wound around the portion 40 and the protrusion 1b, whereby the portion 40 is fixed to the protrusion 1b. Thereby, it is suppressed that the portion 40 is moved by the influence of wind or the like or is moved by birds and beasts.

[0026] As shown in FIG. 7, the protrusion 1b has a base portion 1b1 and a retaining portion 1b2. The base portion 1b1 is connected to the second plate-shaped portion 1a2. The base portion 1b1 protrudes in a direction forming a predetermined angle Φ with respect to the lateral width direction (the extending direction Dr1 of the wire Wr) of the main body portion 1a. Specifically, the angle Φ is, for example, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, and may be within the range between any two of the numerical values exemplified here. For example, the angle Φ is 10 degrees or more and 80 degrees or less. Since the base portion 1b1 forms a predetermined angle Φ, it is easy to guide the portion 40 into the housing case 2 in a curved form. Thereby, the tension of the portion 40 is easily suppressed, and it is easy to avoid the portion 40 from being damaged or the like.

[0027] The retaining portion 1b2 is provided at the tip of the base portion 1b1. In a direction orthogonal to the protruding direction of the protruding portion 1b, the width of the retaining portion 1b2 is larger than the width of the base portion 1b1. Thereby, the retaining portion 1b2 has a function (anti-disengagement function) of preventing the adhesive tape for fixing the portion 40 to the protruding portion 1b described above from coming off. Note that the thickness of the retaining portion 1b2 may be larger than the thickness of the base portion 1b1, and thereby the anti-disengagement function may be exhibited.

[0028] Note that, as shown in FIG. 7, the pair of protruding portions 1b are arranged symmetrically with respect to the center line C of the width of the first plate-like portion 1a1 in the extending direction Dr1 of the wire Wr, but it is not limited thereto. It can be changed according to the position of the insertion port 2c of the housing case 2.

[0029] The thickness of the main body portion 1a and the thickness of the protruding portion 1b may be the same or different. Specifically, for example, the thickness (mm) of the main body portion 1a and the protruding portion 1b is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and it may be within the range between any two of the exemplified numerical values.

[0030] 2-2. Housing case 2 The housing case 2 is a case for housing the connection portion 33 of the communication lines 31, 32, and is also attached to the attachment member 1. In the embodiment, the housing case 2 has an upper housing case 2a and a lower housing case 2b, and a space for housing the connection portion 33 is formed by connecting the upper housing case 2a and the lower housing case 2b. The upper housing case 2a is provided above the lower housing case 2b, and the upper housing case 2a and the lower housing case 2b can be connected by fitting with, for example, claw members or uneven structures.

[0031] The housing case 2 has a pair of left and right insertion ports 2c, a hole portion 2d into which the communication lines 31, 32 are inserted, and a hole portion 2e into which the connection member 4 is inserted.

[0032] The insertion port 2c can be configured, for example, as a notch formed in the upper housing case 2a. Then, when the upper housing case 2a and the lower housing case 2b are connected and combined, an insertion port 2c is formed as an opening for inserting the communication lines 31 and 32. Note that the form of the insertion port 2c is not limited to a notch, and it may be configured as an opening itself formed in the upper housing case 2a or the lower housing case.

[0033] Holes 1a11 and 2d through which the steel wires 31b and 32b are passed are formed in the above-described mounting member 1 and the housing case 2. As shown in FIG. 2, the hole 2d is arranged to communicate (overlap) with the hole 1a11 in a state where the housing case 2 is attached to the mounting member 1. Similar to the hole 1a11, the hole 2d is an opening (through-hole) through which the steel wires 31b and 32b of the communication lines 31 and 32 are passed. As shown in FIG. 8, the hole 2d is formed in the lower housing case 2b. In the extending direction Dr1, the width of the hole 2d is larger than the width of the hole 1a11. Thereby, even if there is a deviation in the fixing position of the housing case 2 or a dimensional deviation of the housing case 2, it is possible to more reliably communicate the hole 2d and the hole 1a11. Here, after the steel wires 31b and 32b are passed through the hole 2d and the hole 1a11, they are tied to themselves to form a ring shape. In FIG. 2, the portion where the steel wires 31b and 32b are tied to themselves is shown as a knot portion 41.

[0034] The hole 2e shown in FIG. 8 is formed so that the connecting member 4 can be inserted. In the embodiment, four holes 2e are formed in the housing case 2 corresponding to the number of the connecting members 4. The hole 2e is formed so as to penetrate the upper housing case 2a and the lower housing case 2b. The hole 2e is arranged to communicate (overlap) with the hole 1a21 (see FIG. 7) of the mounting member 1 in a state where the housing case 2 is attached to the mounting member 1.

[0035] 2-3. Fixing member 3 The fixing member 3 shown in FIGS. 2 and 3 is configured to be able to fix the mounting member 1 to the wire Wr, and the fixing angle of the mounting member 1 to the wire Wr can be changed. As shown in FIG. 7, the fixing member 3 is provided on the first plate-shaped portion 1a1 of the main body portion 1a of the mounting member 1. In the embodiment, two fixing members 3 are arranged side by side in the extending direction Dr1, but the number is not limited to this, and there may be one, or three or more fixing members 3 may be arranged side by side in the extending direction Dr1.

[0036] As shown in FIGS. 9 to 11, the fixing member 3 includes a first fixing component 3a, a washer portion 3b, a second fixing component 3c, and a base portion 3d. The first fixing component 3a and the second fixing component 3c have a function of pressing the wire Wr against the base portion 3d, and are an example of a fixing portion.

[0037] 2-3-1. First fixing component 3a As shown in FIGS. 9 to 12B, the first fixing component 3a has a body portion 3a1 having a female screw portion 3a11, an opening portion 3a2, a protruding portion 3a3, and a cushioning portion 3a4. The first fixing component 3a can be formed of, for example, a nut.

[0038] As shown in FIG. 12B, an opening portion 3a2 is formed in the central portion of the body portion 3a1 to form a cylindrical shape, and a female screw portion 3a11 is formed on the inner peripheral surface of the body portion 3a1. As shown in FIGS. 9 and 12B, the protruding portion 3a3 is formed to protrude from the upper portion of the body portion 3a1. A cushioning portion 3a4, which is an annular member, is provided between the protruding portion 3a3 and the upper end surface of the body portion 3a1.

[0039] The cushioning portion 3a4 shown in FIGS. 9, 12B, and 13 is provided on the upper end surface of the body portion 3a1. The cushioning portion 3a4 is, for example, arranged on the upper end surface of the body portion 3a1, and then caulking is performed on the portion corresponding to the protruding portion (the protruding portion of the first fixing component before caulking is not shown), whereby the protruding portion 3a3 shown in FIG. 12B is formed, and thereby, the cushioning portion 3a4 is sandwiched and fixed between the protruding portion 3a3 and the upper end surface of the body portion 3a1.

[0040] As shown in FIG. 13, the buffer portion 3a4 has an insertion port 3a41, an annular portion 3a42, a protruding piece 3a43, and a notch portion 3a44.

[0041] The annular portion 3a42 is formed in an annular shape, and the insertion port 3a41 is formed therein. The male screw portion 3c1 of the second fixing component 3c is inserted into the insertion port 3a41. As shown in FIGS. 12B and 13, the annular portion 3a42 is formed with a protruding piece 3a43 that protrudes inward in the radial direction and a notch portion 3a44 that is cut out outward in the radial direction. Therefore, the diameter d2 of the insertion port 3a41 at the formation site of the protruding piece 3a43 is smaller than the diameter of the insertion port 3a41 at the formation site of the notch portion 3a44. Here, the diameter d2 of the insertion port 3a41 at the formation site of the protruding piece 3a43 shown in FIG. 13 is smaller than the diameter d1 of the female screw portion 3a11 of the second fixing component 3c as shown in FIG. 12B. Therefore, when the first fixing component 3a and the second fixing component 3c are fastened, the second fixing component 3c is press-fitted into the first fixing component 3a, the fastening force between the first fixing component 3a and the second fixing component 3c is increased, and loosening of the fastening between the second fixing component 3c and the first fixing component 3a is suppressed.

[0042] 2-3-2. Washer portion 3b The washer portion 3b shown in FIGS. 9 and 12A is an annular member disposed between the first fixing component 3a and the mounting member 1, and has a function of suppressing loosening of the fastening between the first fixing component 3a and the second fixing component 3c.

[0043] 2-3-3. Second fixing component 3c The second fixing component 3c shown in FIGS. 9, 10, and 12A has a male screw portion 3c1 and a connecting portion 3c2. The second fixing component 3c can be constituted by, for example, a U-bolt.

[0044] The male screw portion 3c1 is provided at both ends of the connecting portion 3c2. As shown in FIGS. 10 and 12A, the connecting portion 3c2 has a gap Оp through which the wire Wr is inserted. The connecting portion 3c2 is curved along the wire Wr, thereby facilitating the rotation of the fixing member 3 about the wire Wr and easily adjusting the angle of the mounting member 1. When the male screw portion 3c1 of the second fixing part 3c is screwed with the female screw portion 3a11 of the first fixing part 3a, the connecting portion 3c2 of the second fixing part 3c presses the wire Wr against the base portion 3d (the lower surface of the base portion 3d1), whereby the mounting member 1 is fixed to the wire Wr. In other words, the mounting member 1 is fixed to the wire Wr by the wire Wr being pressed against the base portion 3d (the lower surface of the base portion 3d1) by the second fixing part 3c.

[0045] 2-3-4. Base portion 3d The base portion 3d shown in FIGS. 9 to 11 has a base portion 3d1, a protruding leg portion 3d2, an insertion portion 3d3, an arrangement space portion 3d4, and a through hole 3d5.

[0046] The base portion 3d1 is disposed on the lower surface of the mounting member 1, and the lower surface of the base portion 3d1 is pressed by the wire Wr when the male screw portion 3c1 of the second fixing part 3c is screwed with the female screw portion 3a11 of the first fixing part 3a. In the embodiment, four protruding leg portions 3d2 are provided on the base portion 3d1, but for example, two or five or more may be provided. Further, a pair of through holes 3d5 into which the male screw portion 3c1 is inserted are formed in the base portion 3d1.

[0047] The base portion 3d is configured such that the wire Wr can be inserted therethrough. Specifically, as shown in FIG. 11, an insertion portion 3d3 is formed between a pair of protruding leg portions 3d2, and the wire Wr can be inserted into the insertion portion 3d3. The pair of protruding leg portions 3d2 are arranged side by side in a direction Dr2 orthogonal to the extending direction Dr1 of the wire Wr. As shown in FIG. 11, a curved surface 3d21 on which the wire Wr is arranged is formed at the base portions of the pair of protruding leg portions 3d2, facilitating the angle adjustment of the fixing member 3 (mounting member 1). Also, since the movement of the wire Wr is restricted by the protruding leg portions 3d2, an operator can easily attach (easily position) the second fixing component 3c to the wire Wr by arranging the base portion 3d on the wire Wr such that the wire Wr comes between the protruding leg portions 3d2.

[0048] Further, the base portion 3d is configured such that the connection portion 3c2 of the second fixing component 3c can be arranged therein. Specifically, as shown in FIG. 11, an arrangement space portion 3d4, which serves as a space where the connection portion 3c2 can be arranged, is formed between the protruding leg portions 3d2 arranged in the extending direction Dr1 of the wire Wr. The through hole 3d5 is provided at a position facing the arrangement space portion 3d4.

[0049] 2-4. Connecting member 4 The connecting member 4 shown in FIGS. 5, 6, and 14 includes a first connecting component 4a and a second connecting component 4b. The connecting member 4 has a function of fixing the housing case 2 to the mounting member 1. The first connecting component 4a can be constituted by, for example, a nut, and the second connecting component 4b can be constituted by, for example, a bolt.

[0050] The first connecting component 4a basically has the same function as the first fixing component 3a. The first connecting component 4a has a body portion 4a1 and a cushioning portion 4a2. An opening is formed at the central portion of the body portion 4a1 to form a cylindrical shape, and an internal thread portion is formed on the inner peripheral surface of the body portion 4a1. The cushioning portion 4a2 is provided on the upper end surface of the body portion 4a1, and is fixed to the upper end surface of the body portion 4a1 by, for example, caulking (the protruding portion of the first fixing component before caulking is not shown) in the same manner as the first fixing component 3a. A protruding piece 4a21 is formed on the cushioning portion 4a2 in the same manner as the protruding piece 3a43 of the first fixing component 3a. Note that two protruding pieces 3a43 are formed on the first fixing component 3a, while three protruding pieces 4a21 are formed on the first connecting component 4a. The number of these protruding pieces is not particularly limited. Since the connecting member 4 has the cushioning portion 4a2, the second connecting component 4b is press-fitted into the first connecting component 4a, the fastening force between the first connecting component 4a and the second connecting component 4b is increased, and loosening of these fastenings is suppressed.

[0051] The second connecting component 4b has a male screw portion (not shown), and is configured to be screwingly engageable with the female screw portion of the body portion 4a1 of the first connecting component 4a. As shown in FIG. 6, the head of the second connecting component 4b is disposed on the lower surface of the mounting member 1, and the second connecting component 4b is passed through the hole portion 1a21 shown in FIG. 7 and the hole portion 2e shown in FIG. 8.

[0052] 3. An example of the installation method of the holding structure 100 Next, an example of the installation method of the holding structure 100 will be described. The installation method is an installation method of the holding structure 100 that holds the connection portion 33 of the communication lines 31, 32 around the wire Wr, and includes a fixing step, a connecting step, a housing step, a bundling step, a fixing step, and a mounting step. Note that the order of these steps is arbitrary and can be changed as appropriate according to the situation.

[0053] In the fixing step, the mounting member 1 is fixed to the wire Wr. In the fixing step, after passing the wire Wr between the base portion 3d and the second fixing component 3c, the first fixing component 3a and the second fixing component 3c are fastened. Thereby, the mounting member 1 is fixed to the wire Wr. Note that at this stage, it may be temporarily fixed, and final tightening may be performed after steps such as the subsequent connection step. In the fixing step, the fixing member 3 is fixed to the wire Wr such that the mounting member 1 forms an angle of, for example, 20 degrees or more and 60 degrees or less with respect to the horizontal plane. Thereby, it is possible to suppress the holding structure 100 from being exposed to the wind and its position from shifting.

[0054] In the connecting step, the optical fiber lines 31a, 32a of the communication lines 31, 32 are connected. Note that the communication lines 31, 32 are separated in advance into the optical fiber lines 31a, 32a and the steel wires 31b, 32b.

[0055] In the housing step, with the optical fiber lines 31a, 32a taken out from the insertion port 2c, the upper housing case 2a and the lower housing case 2b are connected, and the connecting portion 33 is housed in the housing case 2. Note that the connecting step and the housing step may be performed prior to the fixing step, or may be performed after the bundling step described later.

[0056] In the bundling step, after passing the steel wires 31b, 32b through the hole portion 2d and the hole portion 1a11, they are tied to themselves to form a knot portion 41.

[0057] In the fixing step, for example, a tape having adhesiveness is wound around the protruding portion 1b and the optical fiber lines 31a, 32a to fix the optical fiber lines 31a, 32a to the protruding portion 1b. Note that the fixing step may be performed before the bundling step.

[0058] In the mounting step, the housing case 2 is mounted on the mounting member 1 using the connecting member 4. Note that the mounting step may be performed before the bundling step or the fixing step.

[0059] 4. Operations and effects of the embodiment As a conventional construction example, there is a method in which the holding structure does not include the above-described attachment member or fixing member, and only the housing case is attached to the wire using a steel wire. In this method, the housing case is easily affected by the wind and rotates together with the steel wire, easily causing problems such as the steel wire winding around the wire and the optical fiber line being twisted. Also, when the opening of the optical fiber line is urgent, once the connection of the optical fiber line is completed in the housing case using this method (after the temporary opening work is completed), as this work, the housing case is removed and the optical fiber line is directly drawn into a house or the like, resulting in the demerits of increased working time and working cost.

[0060] On the other hand, the holding structure 100 according to the embodiment has no such demerits. That is, since the holding structure 100 is firmly fixed to the wire Wr, it is difficult to rotate even when affected by the wind, and there is an effect of avoiding the optical fiber line from being twisted. And in the embodiment, since the angle of the attachment member 1 can be adjusted so as not to be easily affected by the wind, the effect is further enhanced.

[0061] Also, since the holding structure 100 is firmly fixed to the wire Wr, there is no problem even if the holding structure 100 is left unattended for a long time. That is, the installation of the holding structure 100 can be carried out as this work instead of as a temporary opening work. In other words, the holding structure 100 according to the embodiment can complete the work that was conventionally carried out in two steps (temporary opening work and this work) in one step, realizing labor saving in construction, and effectively suppressing the working time and working cost.
