  FIG. 8 is a front view showing a configuration of a clip for indirect hot wire construction according to Patent Document 1. FIG. FIG. 8 of the present application corresponds to FIG. Referring to FIG. 8, a clip for indirect hot wire construction (hereinafter abbreviated as a clip) 9 according to Patent Document 1 is composed of a pair of strip-like opening and closing members 91 and 92. The pair of opening and closing members 91 and 92 are divided into holding portions 91a and 92a that can hold an electric wire (not shown) and holding portions 91b and 92b that are held by an insulating operation rod (not shown).

  Referring to FIG. 8, the clip 9 has a connecting portion 9 c that connects the pair of opening and closing members 91 and 92 so that the distal ends of the pair of holding portions 91 a and 92 a can be opened and closed. Further, the clip 9 includes a torsion coil spring 93 that urges a force in a direction in which the tip ends of the clamping portions 91a and 92a are closed. When the pair of gripping portions 91b and 92b are brought close to each other against the urging force of the torsion coil spring 93, the tip portions of the sandwiching portions 91a and 92a can be opened. When the pair of gripping portions 91b and 92b are released, the tip portions of the sandwiching portions 91a and 92a can be closed by being biased by the torsion coil spring 93.

  Referring to FIG. 8, in a state where the pair of holding portions 91a and 92a are closed, the clip 9 is formed so that the outer surfaces of the pair of gripping portions 91b and 92b having a twill-like anti-slip process on the surface thereof are substantially parallel. Therefore, the clip 9 can be gripped with an indirect hot tool from any direction. Further, the clip 9 is provided with large and small concave portions 911 and 912 on the holding surfaces of a pair of opening and closing members 91 and 92 that can hold an electric wire (not shown), and even if the operation is relatively rough, It is assumed that the high-voltage distribution line can be held in either of the large and small concave portions 911 and 912.

  FIG. 9 is a perspective view showing an example of use of the indirect hot wire clip. Referring to FIG. 9, a plurality of high-voltage distribution lines Wh are installed on the top of the utility pole. These high-voltage distribution lines Wh are branched as pull-down lines W. The pull-down line W is supported by the insulator G1 attached to the upper arm metal A1 and the insulator G2 attached to the lower arm metal A2, and then connected to the transformer T through a cutout.

  Referring to FIG. 9, when the transformer T is suspended by the indirect hot wire method, a long insulating sheet S that is folded in half is covered with a pull-down line W between the insulator G1 and the insulator G2. Next, the lower end W of the insulating sheet S is temporarily fixed from above the insulating sheet S with the clip 9t using an insulating operation rod (not shown).

  Further, referring to FIG. 9, the edge line We of the pull-down line W released from the connection with the high-voltage distribution line Wh is arranged along the insulating sheet S so as to be reversed from the insulator G1. Next, the edge line We is temporarily fixed from above the insulating sheet S with the clip 9 (see FIG. 8) using an insulating operation rod (not shown).

In this case, it is difficult to securely clamp the edge line We from above the insulating sheet S with the indirect hot wire clip. Also, using an insulating operation rod, one of the workers holds the edge line We, and another worker uses the insulating operation rod to connect the edge line We together with the insulating sheet S with the clip for indirect hot wire construction. It was necessary to pinch.

  Referring to FIG. 9, the clip 9 t is removed from the insulating sheet S, the edge line We is taken into the insulating sheet S, and the pull-down line W and the edge line We are sandwiched again by the clip 9 t from above the insulating sheet S. A method is also conceivable. However, it is difficult to confirm the position of the edge line We covered with the insulating sheet S, and the clip 9t is removed from the insulating sheet S, so there is a concern that the position of the insulating sheet S may be shifted with respect to the pull-down line W. there were.
