0023]
  A method of using the optical cable housing box 2 will be described with reference to FIGS.
  The operator removes the lid 6 from the housing body 4 of the optical cable housing box 2 and uses it. In the optical cable 8, the position where the optical cable 8 is fixed with respect to the optical cable housing box 2 is determined by the cable fixing unit 20, and the length of the optical cable 8 coming out of the optical cable housing box 2 is determined. In addition, the optical cable 8 is arranged around the anti-mixing frame 18 so that the optical cable 8 is not mixed in the optical cable housing box 2. The connector 10 included in the optical cable 8 is connected to the connector 16 of the second optical cable 14 inside the optical adapter 12.
0024]
  The operation of the cable fixing unit 8 when the operator fixes the optical cable 8 to the optical cable housing box 2 will be described with reference to FIGS.
0025]
  The operator inserts the lid-type gripping member 34a into the groove 42a in a state where the optical cable 8 is placed in the groove 42a of the concave gripping member 32a. By this insertion, a state where the optical cable 8 is loosely inserted is formed in a gap formed by the concave gripping member 32a and the lid gripping member 34a. In this state, the operator inserts the gripping tool 30a into the opening 22a. In this state, the width of the gripping tool 30a is assumed to be larger than the width at a predetermined position in the opening 22a. Here, the width of the gripping tool 30a refers to the distance between the upper end of the compressed surface 38a of the gripping tool 30a and the upper end of the compressed surface 40a. In addition, the width of the predetermined position in the opening 22a means that the predetermined position on the tapered surface 26a is on the tapered surface 28a at the same vertical position as the vertical position in the drawing of this point. This is the length connecting the points.
0026]
  When the gripping tool 30a is inserted into the opening 22a in this state, the gripping tool 30a is tightened from the tapered surface 26a and the tapered surface 28a, and the distance between the support surface 44a and the support surface 46a is shortened. When the gripping tool 30a is inserted to a predetermined position in the opening 22a, the distance between the support surface 44a and the support surface 46a becomes smaller than the diameter of the optical cable 8. At this time, the optical cable 8 is gripped by the gripping tool 30a. Further, at the position where the optical cable 8 is gripped by the gripper 30a, the gripper 30a is engaged with the groove 24a, whereby the gripper 30a is fixed in the opening 22a.
0027]
  In addition, since the plurality of grooves 24a are provided on the tapered surface 26a, the gripping tool 30a can be locked at a position corresponding to the size of the diameter of the optical cable 8.
0028]
  The operation of the optical cable 8 when adjusting the length of the optical cable 8 coming out of the optical cable housing box 2 when the optical cable 8 is fixed to the optical cable housing box 2 will be described with reference to FIG.

  In FIG. 5, the operator holds the upper part of the latching state releasing knob 50a in the direction e from left to right, and pinches the upper part of the auxiliary knob 52a in the direction f from right to left. Then, the latching state releasing knob 50a is deformed so that the support position of the latching state releasing knob 50a becomes the maximum deflection. When the deflection of the latching state release knob 50a exceeds a predetermined amount, the claw 48a is pulled out from the groove 24a. In this state, the gripping tool 30a can be extracted from the opening 22a in the direction g from bottom to top in the drawing. Further, when the gripping tool 30a moves in the upward direction g in the drawing relative to the fixed position of the gripping tool 30a in the opening 22a, the tightening force on the gripping tool 30a is released, and the optical cable 8 is loosely inserted into the gripping tool 30a. It becomes the state. Therefore, the operator can adjust the length of the optical cable 8 coming out of the optical cable housing box 2. Further, if the gripping tool 30a is moved in the upward direction g in the figure so that the gripping tool 30a does not completely come out of the opening 22a, the gripping tool 30a is locked in the opening 22a by the holding portion 25a, and the optical cable 8 is configured to be loosely inserted into the gripping tool 30a.
0030]
  Further, since the gap 54a and the gap 56a are provided, the operator supports the locking state release knob 50a in the direction e from left to right in the figure, and the auxiliary knob 52a from right to left in the figure. When the gripping tool 30a is compressed when supported in the direction f, the optical cable 8 is not compressed.

  like thisReference form 1With this configuration and operation, the gripping tool 30a can be pulled from the inside of the opening 22a in the direction f from the bottom to the top in the figure by pinching the locking release tab 50a and the auxiliary knob 52a. The optical cable 8 does not need to be picked and lifted, and the optical cable 8 is not damaged when the length of the optical cable 8 coming out of the optical cable housing box 2 is adjusted.
  Further, by grasping the locking state release knob 50a and the auxiliary knob 52a, the gripping tool 30a can be inserted into the opening 22a in a state where the claw 48a is not in contact with the tapered surface 26a.
0032]
  In addition, thisreferenceIn the first embodiment, the tapered surface 28a is not provided with a groove. However, by forming a groove similar to the groove 24a on the tapered surface 28a, the gripper 30a is turned over so that the left and right in FIG. Even if it inserts in the part 22a, the user-friendly optical cable storage box 2 which can latch the holding tool 30a in the opening part 22a is realizable.
0033]

  The form of this implementationState 1The structure of the cable fixing part 20 ofreferenceForm 1 andreferenceDifferences from the configuration of Embodiment 2 will be described.
0045]
  The opening 22b is different from the opening 22a in that the peripheral walls have parallel horizontal surfaces in FIG. Further, the groove 24b and the groove 24c are provided on a plane parallel to the peripheral wall of the opening 22b. Further, the tapered surface 28b is different from the tapered surface 28a in that the tapered surface 28b has a gradient formed in the left-right direction and the up-down direction in FIG.
0046]
  Further, the gripping tool 30b can be disassembled so that the lid-type gripping member 34b is pulled out in the vertical direction in FIG. 7 in a state where the holding portion 25b and the claw 48b are engaged.
0047]
  Further, in the gripping tool 30b of FIG. 7, the claw 48b is provided on the concave gripping member 32b positioned so as to cover the lid gripping member 34b, so that the holding portion 25b and the claw 48b are engaged with each other. In FIG. 7, it is difficult to disassemble the gripping tool 30b so that the concave gripping member 32b is lifted in the direction from the back of the paper to the front of the paper.
0048]
  However, as shown in FIG. 10 of the modified example of FIG. 7, if the gripping tool 30e is configured such that the claw 48e is provided on the gripping member (the concave gripping member 32e in FIG. 10) on the bottom surface side of the optical cable storage box 2, In a state where the holding portion 25b and the claw 48e are engaged, the gripping tool 30e can be disassembled so as to lift the lid-type gripping member 34e in the direction from the back of the paper surface toward the front of the paper surface in FIG.
0049]
  AlsoThe figure7 or FIG.In the opening 22b, there is a space in the upward direction on the side where the gripping tools 30b and 30e are inserted.There is a region 82. Also,Of the opening 22bDirection from the back to the frontSpace in the upward direction (direction from the bottom side of the casing to the opening side of the grooves 24b and 24c)There is a region 84.
0050]
  According to the above configuration, the direction in which the gripping tool 30b or 30e is disassembled isaround thereHavespaceRegion 82 or 84InSince the concave gripping member 32b or 32e that is a part of the gripping tool 30b or 30e is fixed to the holding portions 25b and 25c, the lid-type gripping member that is the other part of the gripping tool 30b or 30e 34b or 34e can be taken out from the opening 22b. Therefore, it is possible to perform the work of removing the optical cable 8 from the gripping tool 30b or 30e and the work of attaching the optical cable 8 to the gripping tool 30b or 30e with a part of the gripping tool 30b or 30e fixed.
0051]
  Next, in addition to this embodiment1The configuration ofreferenceDifferences from the configuration of form 2 will be described.
0052]
  The gripping tool 30b differs from the gripping tool 30a in that it has two locking state release knobs 50b and 51b instead of one locking state release knob and an auxiliary knob. Further, the gripper 30b is provided with a claw 48b and a claw (not shown) provided in the vicinity of the locking state release knob 51b, and a groove is formed only on the groove 24b on the peripheral wall of the opening 22b. Instead, the groove 24c is provided on the surface facing the surface on which the groove 24b is provided.
0053]
  According to the above configuration, since the gripping tool 30b is locked at two points, further stable locking can be realized.
0054]
  This embodiment1Since the operator can adjust the fixing position of the optical cable 8 with respect to the optical cable housing box 2 while holding the holding tool 30b on the holding portion, the holding tool 30b is opened while the operator is working. It is possible to prevent the gripping tool 30b from being lost due to detachment from the inside of 22b.
0055]
Embodiment2.
  This embodiment2The configuration will be described with reference to FIG.

  In the figure, reference numeral 64 denotes a stopper provided on a part of the housing body 4.
0057]
  About another structure, the same code | symbol is attached | subjected and description is abbreviate | omitted.
0058]
  According to the above configuration, even when the gripping tool 30b is mistakenly moved with excessive force when the gripping tool 30b is removed from the opening 22a, the stopper 64 can stop the movement of the gripping tool 30b. Therefore, it is possible to prevent the gripping tool 30b from dropping due to momentum.
0059]
  This embodiment2Since it can prevent that the holding | grip tool 30b remove | deviates from the cable fixing | fixed part 20 more than necessary, it can prevent that an operator slips a hand while an operator is working.
0060]
Embodiment3.
    This embodiment3Will be described with reference to FIGS. 12 (a), 12 (b), 13 (a), and 13 (b).
0061]
  In FIG. 12A, the lid 6 is removed from the optical cable housing box 2, and a part of the side surface of the housing body 4 in front of the paper surface is broken.3It is a perspective view showing the cable fixing | fixed part 20 in. FIG. 12B is a plan view when the optical cable fixing portion 20 is viewed in the direction h orthogonal to the bottom surface of the housing body 4 in FIG. Moreover, in FIG. 12A and FIG. 12B, the gripping tool 30c is inserted partway through the opening 22b.
0062]
  FIG. 13A shows the gripping tool 30c in the direction i perpendicular to the direction in which the gripping tool 30c is inserted into the opening 22b on the bottom surface of the housing body 4 in FIG. FIG. FIG. 13B shows a case where the gripping tool 30c and a part of the housing body 4 are viewed in the direction j opposite to the direction in which the gripping tool 30c is inserted into the opening 22b in FIG. FIG.
0063]
  13A and 13B, reference numerals 66 and 68 denote sliding pieces provided on the gripping tool 30c, and reference numeral 70 denotes a sliding piece 66 and sliding pieces 68 provided on the bottom surface of the housing body 4. It is a sliding groove that slides together. The bottom surface of the housing body 4 is a wall on the peripheral surface of the hole 9. The sliding piece 66 and the sliding piece 68 are loosely attached to the sliding groove 70. A configuration example for realizing this attachment and sliding will be described with reference to FIGS. 13 (a) and 13 (b).
0064]
  The sliding piece 66 and the sliding piece 68 are formed in this embodiment.3It has the property of elastically deforming and bending to the extent that it conforms to. The sliding piece 66 has a claw 67 provided with a taper 71, and the sliding piece 68 has a claw 69 provided with a taper 73. In addition, it is desirable that the sliding piece 66 and the sliding piece 68 are provided on the gripping tool 30 c so that a gap is generated between the sliding piece 66 and the sliding piece 68.
0065]
  In FIG. 13B, the width k of the sliding groove 70 is smaller than the length l from the outer edge of the claw 67 to the outer edge of the claw 69 in the gripping tool 30c.
0066]
  The operation of loosely attaching the gripping tool 30c to the sliding groove 70 will be described with reference to FIGS. 13 (a) and 13 (b).
0067]
  The operator moves the gripping tool 30c toward the sliding groove 70 in a state where the position of the sliding pieces 66 and 68 and the position of the sliding groove 70 in the left-right direction in FIG. Press. In that case, the claw 67 and the claw 69 receive a reaction force from the periphery of the mouth of the sliding groove 70 on the surface where the taper 71 is provided or the surface where the taper 73 is provided.
0068]
  Then, the sliding pieces 66 and 68 are bent, or the claw 67 or the claw 69 is elastically deformed, and the length l from the outer edge of the claw 67 to the outer edge of the claw 69 in the gripping tool 30c is the width k of the sliding groove 70. Less than or equal to. Therefore, the claw 67 and the claw 69 can pass through the sliding groove 70. Further, when the claw 67 and the claw 69 completely pass through the sliding groove 70, the claw 67 and the claw 69 are located below the bottom surface of the housing body 4.
0069]
  When the claw 67 and the claw 69 are positioned below the bottom surface of the housing body 4 in FIG. 13B, the claw 67 and the claw 69 do not receive a reaction force from the peripheral wall of the sliding groove 70. The joining piece 66 and the sliding piece 68 return to the shape in the state before the state in which the gripping tool 30 c is pressed toward the sliding groove 70. Therefore, the width l including the claw 67 and the claw 69 in the gripping tool 30 c is larger than the width k of the sliding groove 70. Therefore, even if the gripping tool 30c is lifted as it is in order to separate the gripping tool 30c from the bottom surface of the housing body 4, the sliding groove 70 prevents the movement of the claw 67 and the claw 69. Therefore, in this case, the gripping tool 30 c is not separated from the bottom surface of the housing body 4.
0070]
  On the other hand, if it is desired to separate the gripping tool 30 c from the housing body 4, the width l including the claw 67 and the claw 69 is made larger than the width k of the sliding groove 70 in the gripping tool 30 c by gripping the claw 67 and the claw 69. The gripper 30c may be moved in such a direction as to be separated from the housing body 4.
0071]
  Further, when the gripping tool 30c is slid on the sliding groove 70, the length of the sliding groove 70 is long enough that a part of the gripping tool 30c comes out of the opening 22c. The operator does not need to work in the narrow opening 22b, and the optical cable housing box 2 that makes the work easier is realized.
0072]
  Further, the length of the sliding groove 70 is long enough to allow the gripping tool 30c to come out of the opening 22b along the sliding groove 70, so that the gripping tool 30c is attached to the housing body 4. In the loosely attached state, it can be extracted from the opening 22b. If the gripping tool 30c is extracted from the opening 22b, a work area is created around the gripping tool 30c, so that the optical cable housing box 2 is realized in which the operator can perform operations such as adjusting the fixing position of the optical cable 8. Is done.
0073]
  About another structure, the same code | symbol is attached | subjected and description is abbreviate | omitted.
0074]
  This embodiment3According to the above, since the sliding groove 70 provided on the peripheral surface of the hole 9 and the sliding pieces 66 and 68 that slide on the sliding groove 70 provided on the gripping tool 30c are provided, the gripping tool 30c is provided. The insertion / removal operation becomes easier.

Reference form 3.
  thisReference form 3Will be described with reference to FIGS. 14 and 15.
0077]
  In the figure, reference numeral 76 denotes a cover for protecting the optical cable 8. In FIG. 14, this cover 76 is provided integrally with the concave gripping member 32 d and includes a semi-cylindrical cover 78 and a semi-cylindrical cover 80 that covers the semi-cylindrical cover 78. The semi-cylindrical cover 78 and the semi-cylindrical cover 80 are formed so that each side thereof is integrally bent. Further, a groove (not shown) is provided in the semi-cylindrical cover 78, and a claw (not shown) hooked in the groove (not shown) is provided in the semi-cylindrical cover 80, so that the optical cable 8 is wrapped. Is done.
0078]
  The cover 76 has a predetermined flexibility while having a predetermined strength. For example, if the cover 76 is integrally formed with nylon (Nylon is a trademark of Toray) together with the gripping tool 30d, the strength is sufficient, but the flexibility needs to be further improved. Therefore, a slit can be provided in the cover 76, so that a cover with better flexibility and strength can be produced.
0079]
  If the cover is formed independently of the gripping tool 30d, the cover is formed in advance using a highly flexible material. For example, polypropylene or hard rubber is used. In this case, the cover 76 may not be connected to the gripping tool. However, the cover 76 needs to be arranged so as to be positioned inside and outside the optical cable housing box 2 at the exit of the optical cable 8 from the optical cable housing box 2 in the opening 22a.
0080]
  According to the above configuration, when the optical cable 8 is picked through the cover 76, the core wire of the optical cable 8 does not hurt.
0081]
  Further, since the cover 76 is flexible, the optical cable 8 has a harder property than the optical cable 4 in the vicinity of the opening from which the optical cable 8 protrudes from the housing main body 4. As a fulcrum, it is also prevented from being bent.
In addition, when the gripping tool 30d grips the optical cable 8 and is locked in the opening 22a, if the tip of the gripping tool 30d is designed to protrude from the opening 22a, the gripping tool 30d itself is the optical cable 8 The same effect as that of the cover 76 can be obtained.
0082]
  thisReference form 3According to the above, since the gripping tool can be removed from the cable fixing portion 20 by pinching the cover 76, the optical cable 8 is not compressed and applied to the optical cable 8 when the optical cable 8 is removed from the cable fixing portion 20. The optical cable housing box 2 with less burden is realized.
0083]
【The invention's effect】
  According to the present invention, when removing the optical cable from the cable fixing portion, there is no need to pick and lift the optical cable, so the burden on the optical cable is small.,AlsoSince the gripping tool is inserted into and removed from the cable fixing portion in a state where the claw of the gripping tool does not hit the groove, an optical cable housing box with less damage to the groove is realized.
0084]
  According to this invention, since the inner lid for covering the opening is provided in the housing body, the gripper can be used when the operator is working to adjust the position for fixing the optical cable with respect to the optical cable housing box. Is prevented from coming off from the optical cable housing box.
0085]
  According to the present invention, the operator can adjust the fixing position of the optical cable with respect to the optical cable housing box while holding the gripping tool on the holding portion, so that the gripping tool is detached from the holding portion while the operator is working. It is possible to prevent the gripping tool from being lost.
0086]
  According to the present invention, since the gripping tool can be prevented from being unnecessarily detached from the cable fixing part, the gripper is slipped from the cable fixing part more than necessary while the work is in progress. Can be prevented.
0087]
  According to this invention, since the gripping tool can be slid and inserted / removed, the insertion / removal operation of the gripping tool is facilitated.The
