Description

  The present invention relates to a thin cable surplus length processing tool suitable for performing surplus length processing of a thin cable such as an FTTH drop optical cable and an automatic meter reading optical cable.

Conventionally, the extra length processing of a cable is performed by fixing the extra length processing metal fitting to the armrest attached to the utility pole, and supporting the extra length wound several times with the extra length processing metal fitting (for example, See Patent Document 1 below).
Further, when the distance between the utility poles increases due to the rebuilding of the utility poles, the extra length supported by the extra length processing bracket is fed out, and the cables are moved without being cut.

Patent Documents 2 and 3 below disclose surplus length storage cases for securing a surplus length even in a thin cable (a cable having a diameter of about 1 cm or less) such as an FTTH drop optical cable or an automatic meter reading optical cable. However, when the extra length is not taken, the connection is made or redrawn.
Further, in the case of connection in the middle, a connection material is required, but if the connection loss is not considered, the connection material can be reduced by a connection method using a mechanical splice (for example, see Patent Document 4 below).

Embodiments of the thin cable surplus length processing tool of the present invention will be described below with reference to the drawings.
First, a thin cable surplus length processing tool 10 according to a first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1A, the thin cable surplus length processing tool 10 according to the present embodiment includes a fixing member 11, a rotating member 12, a cable protection member 13, and a rotating handle 14.

Here, the fixing member 11 is used to fix the thin cable surplus length processing tool 10 to the armrest 3 attached to the utility pole 2 and to wind up the surplus length of the thin cable 1.
Therefore, the fixing member 11 is attached to the cylindrical winding part 11a having a through-hole formed at the center and the end surface (end surface on the rotating handle 14 side) of the winding part 11a, and is wound to the center. And a disk-shaped fixing part 11b in which a through hole connected to the through hole of the part 11a is formed.
Considering that the extra length of the thin cable 1 is normally 10 m to 40 m, the diameter of the winding part 11a is about 30 cm, and the length of the winding part 11a is at least about 30 cm. Further, the distal end portion (the end portion on the cable protection member 13 side) of the winding portion 11a does not protrude from the winding portion 11a when the extra length of the small-diameter cable 1 is wound around the winding portion 11a as will be described later. As described above, the protrusion preventing portion 11c has an outer diameter that is increased in a tapered shape.
The diameter of the fixing part 11b is larger than the diameter of the winding part 11a. Further, as shown in FIG. 1, by fixing a part of the outer peripheral surface of the fixing portion 11 b to the arm metal 3, the thin cable extra length processing tool 10 can be fixed to the arm metal 3.

The rotating member 12 includes a columnar main body portion and a disc portion attached to the end surface of the main body portion (end surface on the rotating handle 14 side).
The main body of the rotating member 12 has a diameter of the winding of the fixing member 11 so that the leading end can protrude from the through hole formed in the winding portion 11a and the fixing portion 11b of the fixing member 11 and the tip portion can protrude from the through hole. The diameter is smaller than the diameter of the through hole formed in the part 11 a and the fixing part 11 b, and the length is about several cm larger than the length of the fixing member 11.
The diameter of the disc part is larger than the diameter of the main body part and smaller than the diameter of the fixing part 11 b of the fixing member 11.

The cable protection member 13 is for protecting the thin cable 1 from being damaged when the extra length of the thin cable 1 is wound.

Next, the usage method of the thin cable surplus length processing tool 20 is demonstrated with reference to FIG.
As shown in FIG. 8A, the worker fixes the lower fixing member 21 </ b> B to the arm metal 3 attached to the utility pole 2.

  Subsequently, the worker stores the right rotating member 22R in the right half of the lower fixing member 21B, as shown in FIG. 8B.

  Subsequently, as shown in FIG. 8 (c), the worker moves the right end formed in the right semicircular groove 22Rca formed in the right end fixing portion 22Rc and the right protection portion 22Rd in the distal end of the small-diameter cable 1. Insert into the semicircular groove 22Rda.

As shown in FIG. 3, after the left rotating member 22L is stored in the left half of the lower fixing member 21B, the rotating handle 23 is attached to the rotating member 22.

Subsequently, the worker rotates the rotary member 23 in the same direction by rotating the rotary handle 23 clockwise toward the thin cable surplus length processing tool 10 to rotate the surplus length of the thin cable 1. The member 22 is wound from the end of the left winding portion 22Lb and the right winding portion 22Rb toward the tip.
At this time, if the extra length of the small-diameter cable 1 remains after only one winding, the extra length of the small-diameter cable 1 is wound around the left winding portion 22Lb and the right winding portion 22Rb of the rotating member 22 a plurality of times. To go.

  Subsequently, the worker covers the lower fixing member 21B with the upper fixing member 21U.

  As a result, the extra length processing of the thin cable 1 can be performed, and when the distance between the utility poles increases due to the rebuilding of the utility pole, the operator moves the rotary handle 23 toward the extra diameter cable extra length processing tool 20. Then, when the worker in the next utility pole or the aerial work vehicle pulls the thin cable 1 in the X direction shown in FIG. The extra length of the thin cable 1 can be easily extended.

In order to facilitate rotation of the rotating member 22, at least three pulleys are arranged so that the outer peripheral surface of the rotating member of the pulley is in contact with the inner peripheral surface of the fixing member 21 (the upper fixing member 21U and the lower fixing member 21B). Alternatively, the left end side fixing member 22La and the right end side fixing member 22Ra may be attached to the outer peripheral portions of the left end side fixing member 22La at equal intervals along the circumferential direction.
In this case, if at least three pulleys are similarly attached to the outer peripheral portions of the left tip side fixing member 22Lc and the right tip side fixing member 22Rc, the rotating member 22 can be more easily rotated.

Moreover, in the thin cable surplus length processing tool 20, although the rotating member 22 was comprised with the left rotating member 22L and the right rotating member 22R, you may comprise with an upper rotating member and a lower rotating member.
In this case, the upper rotating member has the same configuration as that obtained by rotating the left rotating member 22L by 90 degrees, and the lower rotating member has the same configuration as that obtained by rotating the right rotating member 22R by 90 degrees.
However, as the locking convex portion and the locking concave portion for joining the upper rotating member and the lower rotating member, instead of the locking convex portions 22Laa and 22Lba and the locking concave portions 22Raa and 22Rba, the downward rotation For example, a rectangular concave locking recess is formed at the center of the upper surface (the surface corresponding to the right side of the left rotating member 22L) of the lower winding portion of the member (corresponding to the right winding portion 22Rb) For example, a rectangular convex protrusion is formed at the center of the lower surface (the surface corresponding to the left side of the right rotating member 22R) of the upper winding portion of the rotating member (corresponding to the left winding portion 22Lb). When the upper rotating member and the lower rotating member are coupled, the locking projection is fitted into the locking recess.
Further, when using such a thin cable surplus length processing tool, the worker stores the lower rotating member in the lower fixing member with the upper surface facing upward, and then the above-described thin cable surplus length processing tool. The operation is performed in the same procedure as in No. 20.
