  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
[Configuration of clips for indirect hot-wire construction]
Initially, the structure of the clip for indirect hot wire construction concerning this embodiment is demonstrated.
The clip 1 for indirect hot-wire construction temporarily cuts the high-voltage underline LA left on the high-voltage line M1 by cutting when the distribution transformer 100 is replaced or the high-voltage cut-out is replaced by indirect hot-wire work. (See FIG. 2).

  As shown in FIG. 1, the indirect hot wire clip 1 includes a first clamping member 2, a second clamping member 3, and a coil spring 4.

The 1st clamping member 2 and the 2nd clamping member 3 are formed in the rectangular plate shape bent in the position where the longitudinal direction deviated. The first clamping member 2 and the second clamping member 3 are made of hard plastic and have insulating properties.
The 1st clamping member 2 and the 2nd clamping member 3 have the axis | shafts 2a and 3a extended in a width direction in a bending part. The first clamping member 2 and the second clamping member 3 are pivotally supported so that the shafts 2a and 3a are aligned with each other, and the shafts 2a and 3a are pivotable with respect to each other.
Each of the first clamping member 2 and the second clamping member 3 has a clamping part 5 on one side and a gripping part 6 on the other side with the shafts 2a and 3a as a boundary.

Each clamping part 5 is the same substantially rectangular parallelepiped shape, and is connected with the axis | shafts 2a and 3a in the base end side.
Each clamping part 5 has two recessed parts 51 and 52 arranged in the longitudinal direction on the opposing inner surfaces of the pair of clamping parts 5 and 5 of the first clamping member 2 and the second clamping member 3. The concave portion 51 on the distal end side that is opposite to the proximal end side of each sandwiching portion 5 has a curved arc shape. The concave portion 52 on the proximal end side of each sandwiching portion 5 is rectangular.
Each clamping part 5 has a through hole 53 that penetrates both side surfaces at the tip. The hole diameter of the through-hole 53 is set larger than the diameter of the rod-shaped body so that the rod-shaped body of the indirect sheet 10 (see FIG. 2) can be inserted into the through-hole 53.

  Each gripping part 6 has the same substantially rectangular parallelepiped shape smaller than the clamping part 5, and is provided on the opposite side of the clamping part 5 with respect to the shafts 2a and 3a. The outer surface of each gripping portion 6 is processed into a grip surface 61 that has been subjected to anti-slip processing. The upper end portion of each gripping portion 6 has a flange portion 62 that protrudes outward.

  The coil spring 4 includes a main body 41 on the shafts 2a and 3a and each end 42 on each of the pair of gripping portions 6 and 6. The coil spring 4 biases the force in a direction to close the pair of sandwiching portions 5 and 5. For this reason, the operator can open the pair of holding portions 5 and 5 when the pair of gripping portions 6 and 6 are brought close to the urging force of the coil spring 4 using an indirect hot wire tool. On the other hand, when the operator releases the pair of gripping portions 6, 6, the pair of sandwiching portions 5, 5 is closed by the bias of the coil spring 4.

Here, the outer surface of each clamping part 5 has a plurality of hook-shaped protrusions 7 protruding outward. The protrusion 7 is made of soft silicon, plastic, or ethylene propylene rubber, and has flexibility. The width of the protruding portion 7 matches the width of the outer surface of each clamping portion 5. As will be described later, the protruding amount of the protruding portion 7 is set to a length having a margin on the distal end side even when the high voltage underline LA is sandwiched between the protruding portions 7.
The plurality of projecting portions 7 are arranged in a line in the longitudinal direction of each sandwiching portion 5 of the indirect hot wire clip 1. The gap between the protrusions 7 is set to a size that allows the high-voltage underline LA to be sandwiched and does not allow the sandwiched high-pressure underline LA to escape.

[Usage example 1 of indirect live work clips]
As shown in FIG. 2, the indirect sheet 10 is cut and cut to the high voltage line M <b> 1 in order to cut the high voltage underline L <b> 1 when the distribution transformer 100 is replaced or the high voltage cutout is replaced by indirect hot wire construction. Temporarily fix the high pressure underline LA remaining on the side.

  First, the worker attaches the indirect hot wire clip 1 to the high voltage line M1. The indirect live work construction clip 1 uses the indirect live tool to bring the pair of gripping parts 6 and 6 close to the urging force of the coil spring 4 and open the pair of holding parts 5 and 5 to sandwich the high-voltage line M1.

  Next, when the operator cuts the high-voltage underline L1 connected to the high-voltage line M1 by the connector, the high-voltage underline LA on the side of the cut high-voltage line M1 protrudes short from the high-voltage line M1.

  Next, the operator selects one of the plurality of protrusions 7 provided on the outer surfaces of the pair of sandwiching portions 5 and 5 in the indirect hot-wire construction clip 1 with the cut high-voltage underline LA on the high-voltage line M1 side. It is inserted between the protrusions 7 and temporarily fixed. At this time, the tip LS where the charging part is exposed in the high voltage pull-down line LA on the cut high voltage line M1 side is arranged at the approximate center between the protrusions 7 whose width is matched with the width of the outer surface of the clamping part 5. Thereby, the front end LS where the charging part of the high-voltage underline LA is exposed can be safely protected only by sandwiching the cut high-voltage underline LA on the high-voltage line M1 side between the protrusions 7.

  According to the clip 1 for indirect hot wire construction according to the present embodiment described above, the following effects are obtained.

  (1) The indirect hot wire clip 1 includes a pair of holding parts 5 and 5 that are opened and closed, a pair of gripping parts 6 and 6 that open and close the pair of holding parts 5 and 5, and a pair of holding parts 5 and 5. And a plurality of protrusions 7 disposed on the outer surface of the. For this reason, the high-voltage underline LA on the high-voltage line M <b> 1 cut during the indirect hot-wire work is sandwiched between any one of the plurality of protrusions 7 of the indirect hot-wire work clip 1. Therefore, the operator can easily temporarily fix the high-voltage down line LA on the high-voltage line M1 side cut using only the indirect hot-wire construction clip 1 attached to the high-voltage line M1 without requiring another tool. As a result, the number of tools required for work can be reduced, and work efficiency can be improved.

  (2) The plurality of protrusions 7 are made of a flexible resin member. Accordingly, the plurality of protrusions 7 are easily deformed, and the high-voltage underline LA is easily sandwiched between the protrusions 7.

Second Embodiment
In the present embodiment, since the plurality of protrusions 7A are different from the above embodiment, the characteristic portions will be described, and the description of the same configuration as the above embodiment will be omitted.

  Unlike the above-described embodiment, the indirect hot work clip 1A was removed from the terminal 101 in the vertical direction when the distribution transformer 100 was replaced or the high voltage cutout was replaced by the indirect hot work. The high-voltage underline LB can be temporarily fixed (see FIG. 4).

[Configuration of clips for indirect hot-wire construction]
Here, the outer surface of each clamping part 5 has a plurality of rod-shaped protrusions 7A protruding outward. The projection 7A is made of soft silicon, plastic, or ethylene propylene rubber, and has flexibility. The protruding amount of the protruding portion 7A is set to a length having a margin on the distal end side even when the high voltage underline LB is sandwiched between the protruding portions 7A.

The plurality of projecting portions 7A are arranged in two rows in the longitudinal direction of the respective sandwiching portions 5 of the indirect hot wire clip 1A that matches the width direction of the indirect sheet 10. This two-row arrangement is configured in an equal arrangement in which a plurality of protrusions 7A are arranged in the same order in the longitudinal direction of each sandwiching portion 5.
The gap between the protrusions 7A is set to a size that allows the high-voltage underline LB to be sandwiched and does not allow the sandwiched high-pressure underline LB to escape.

[Usage example 2 of indirect live-line construction clip]
As shown in FIG. 4, in the indirect hot wire construction, the high voltage pull-down line L <b> 1 is removed from the high voltage line M <b> 1 to open the electric circuit. The high-voltage underline LB removed at this time is a protrusion of any one of the plurality of protrusions 7A provided on the outer surfaces of the pair of sandwiching portions 5 and 5 in the indirect hot wire clip 1A attached to the indirect sheet 10. Put between 7A and temporarily fix.

  First, an operator opens a pair of clamping parts of the first clip 11 and the second clip 12 of the indirect sheet 10 by using an indirect hot wire tool, and attaches the first clip 11 and the second clip 12 to the high-pressure underline L1. . Thereby, the indirect sheet | seat 10 is coat | covered by the high voltage underline L1.

  Next, the worker attaches the indirect hot wire clip 1A to the indirect sheet 10 covered with the high-voltage underline L1. The indirect hot work clip 1A sandwiches the indirect sheet 10 in a state where the pair of gripping portions 6 and 6 are brought close to the urging force of the coil spring 4 and the holding portions 5 and 5 are opened using an indirect hot wire tool. . And the clip 1A for indirect hot wire construction which pinched | interposed the indirect sheet | seat 10 releases a pair of holding parts 6 and 6 using an indirect hot wire tool, and closes a pair of holding parts 5 and 5 by the urging | biasing of the coil spring 4. Thus, the indirect sheet 10 is attached.

  The indirect live work clip 1A attached to the indirect sheet 10 is in a state in which the longitudinal direction is extended in the horizontal direction.

  When the operator removes the high-voltage underline L1 connected to the high-voltage line M1 by the connector, the removed high-voltage underline LB is perpendicular to the terminal 101 in parallel with the indirect sheet 10 covering the high-voltage underline L1. It hangs down. At this time, the removed high-voltage underline LB hanging from the terminal 101 in the vertical direction intersects with the indirect hot-line work clip 1A attached to the indirect sheet 10 and extending in the horizontal direction.

Next, the worker places the high-voltage underline LB at a position where the removed high-voltage underline LB intersects the indirect hot-line work clip 1A, and the pair of holding portions 5 and 5 in the indirect live-line work clip 1A. Between the protrusions 7A of the plurality of protrusions 7A arranged in the horizontal direction and temporarily fixed.
Here, since the plurality of projecting portions 7A are equally arranged in two rows in the longitudinal direction on the outer surfaces of the pair of sandwiching portions 5 and 5, the high pressure pull-down lines LB hanging in the vertical direction are simultaneously multiplexed in two rows. Can be sandwiched between them. As a result, the high-voltage underline LB is sandwiched between the protrusions 7A in multiple layers, and even if the high-voltage underline LB is vibrated by wind or the like, it is difficult to come off between the protrusions 7A.

  According to the indirect hot-wire construction clip 1A according to the present embodiment described above, the effects (1) and (2) are obtained as in the above-described embodiment.

  Note that the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the scope of the present invention.

  In the second embodiment, the plurality of projecting portions 7A are arranged in two rows in the longitudinal direction on the outer surfaces of the pair of sandwiching portions 5 and 5, but are not limited thereto. For example, the plurality of protruding portions 7A may be arranged in three or more rows in the longitudinal direction on the outer surfaces of the pair of sandwiching portions 5 and 5.

  Further, even in the plurality of protrusions 7A in the second embodiment, one of the plurality of protrusions 7A in the two rows arranged in the longitudinal direction on the outer surfaces of the pair of sandwiching portions 5 and 5 as in the first embodiment. The tip LS of the high-voltage underline LA on the high-voltage line M1 side cut only between any one of the plurality of protrusions 7A in the row may be sandwiched between the protrusions 7A. In this case, the tip LS where the charging part of the high-voltage underline LA is exposed can be safely protected.
