  The pair of sandwiching members 2 and 2 sandwich, for example, an insulating sheet (not shown) placed on the charging portion of the electric wire in the high-voltage distribution line between the distal ends 21 and 21 of the pair of sandwiching members 2 and 2. The pair of sandwiching members 2 and 2 are formed in an elongated band shape from an electrically insulating material such as synthetic resin, and a plurality of reinforcing ribs 23 and 23 are formed on the outer surfaces thereof.

  The connecting portion 3 is disposed on one end (base end) side 22, 22 in the longitudinal direction of the pair of sandwiching members 2, 2. The connecting portion 3 includes a fixing pin 31 inserted in the width direction of the pair of sandwiching members 2, 2 and a base end side 22, 22 of the pair of sandwiching members 2, 2 outside the insertion portion of the fixing pin 31. And an annular member 32 fitted so as to surround the outer peripheral portion. The connection part 3 connects the front end sides 21 and 21 of the pair of sandwiching members 2 and 2 so as to be openable and closable by rotating the pair of sandwiching members 2 and 2 around the fixing pin 31.

  As shown in FIG. 2, the pair of gripping members 5 and 5 are connected to the base end sides 22 and 22 of the pair of sandwiching members 2 and 2, respectively. The pair of gripping members 5 and 5 are separated from the pair of sandwiching members 2 and 2 from the connecting portion 3 so as to be gradually separated from each other in the closed state in which the distal end sides 21 and 21 of the pair of sandwiching members 2 and 2 are in contact with each other. It extends in the opposite diagonal direction. The pair of gripping members 5 and 5 are formed integrally with the pair of sandwiching members 2 and 2 by using, for example, an injection molding machine (not shown) using an electrically insulating material such as synthetic resin. The pair of gripping members 5 and 5 are moved toward each other against the spring force of the spring 4 described later in a state where the pair of gripping members 5 and 5 are separated from each other, so 21 and 21 can be switched to an open state.

  As shown in FIG. 2, the spring 4 is a helical metal spring and includes a winding part 41 and a pair of linear parts 42 and 42 extending from both ends of the winding part 41. The winding part 41 is wound around the fixing pin 31 of the connecting part 3. The pair of linear portions 42, 42 extend from the winding portion 41 so as to expand toward the end, and are assembled so as to press against the opposing surface sides of the pair of gripping members 5, 5. Accordingly, the pair of sandwiching members 2 and 2 are biased in the direction in which the distal ends 21 and 21 of the pair of sandwiching members 2 and 2 come into contact with each other by the spring force (biasing force) held by the spring 4. The spring 4 is covered with a pair of gripping members 5 and 5 so as not to be exposed on the surface.

Next, the configuration of the pair of gripping members 5 and 5 that are characteristic portions of the clip 1 for indirect hot wire construction according to the first embodiment will be described in detail. In addition, since a pair of holding members 5 and 5 are the completely same structures, in the following description, one holding member 5 is demonstrated.

The outer periphery of the inner plate-like portion 52B is formed in a polygonal shape having a plurality of vertices P (for example, twelve) inscribed in the outer frame portion 51 along the circumferential direction. The internal angle θ of each of the vertices P inscribed in the outer frame portion 51 is formed to be approximately 90 degrees. As shown in FIG. 4, the inner plate-like portion 52 </ b> B is arranged so that two pairs of opposing sides 521 and 522 are along the longitudinal direction of the indirect hot wire clip 1.

  The indirect hot-wire construction clip 1 of the first embodiment configured as described above is, for example, in the hot-wire construction of the high-voltage distribution line, so that, for example, the insulating sheet placed on the charging portion of the electric wire does not come off during the construction. This is used when the insulating sheet is temporarily fixed to the electric wire by sandwiching the insulating sheet between the distal end sides 21 and 21 of the pair of sandwiching members 2 and 2 that are biased to the closed position by the spring force of the spring 4.

  In such a mode of use, the pair of gripping members 5 and 5 that are separated from each other with the pair of sandwiching members 2 and 2 in the closed position are provided at the distal ends of the insulating yoke 10 as an indirect hot wire tool.
