The electric wire 1 has an exposed portion 1c from which a predetermined portion of the insulating portion 1b has been peeled off.

  As shown in FIG. 9, the wire cover 10 includes the first half cylinder 30 and the second half cylinder 30 so that the angle γ formed by the first half cylinder 30 and the second half cylinder 40 is a predetermined obtuse angle. After the second half cylinders 40 are brought close to each other (the cylinder body 20 is somewhat closed), the holding member 70 is held by the indirect hot wire tool 2 such as Yatco, and the inner surface 33 , 43 is directed toward the operator and is hooked to the electric wire 1 with the gripping member 70 facing downward. Since the cylindrical body 20 is in a somewhat closed state, it is easily hooked on the electric wire 1. Here, when the electric wire cover 10 is brought close to the electric wire 1 in a state where the holding member 70 is held by the indirect hot wire tool 2, the rotation restricting portion 72 is placed on the outer surface 34 of the first half cylinder 30. By contacting, the cylinder body 20 is restricted from rotating in the direction of escaping from the operator (direction E in FIG. 9). In other words, the cylindrical body 20 is abutted and supported by the rotation restricting portion 72. Thereby, since it can prevent that the cylinder main body 20 falls down toward an operator, the cover 10 for electric wires can be stably mounted | worn with respect to the electric wire 1, and each other of the half cylinders 30 and 40 can be attached. Since the electric wire cover 10 can be mounted in a state where the edges 32 and 42 can be visually recognized by the operator, there is an effect that workability is improved.

  When the electric wire cover 10 is hooked on the electric wire 1, the distance l between the outer ends of the two protrusion-like movement restricting portions 38 (see FIG. 1) and the distance l between the outer ends of the two ring-like movement restricting portions 48 are The cut surface of the insulating portion 1b is substantially the same as the length m of the exposed portion 1c, and the outer ends of the projecting piece-like movement restricting portions 38 and the outer ends of the ring-like movement restricting portions 48 are on both sides of the exposed portion 1c. Positioned to abut 1d. As a result, the movement of the wire cover 10 in the longitudinal direction with respect to the electric wire 1 is restricted by the protrusion-like movement restricting portion 38 and the ring-like movement restricting portion 48. The distance l may be shorter than the length m.

  Next, as shown in FIG. 10, the cylindrical body 20 is sandwiched between predetermined locations of the first half cylinder 30 and the second half cylinder 40 by the indirect hot wire tool 2. The cylindrical main body 20 is completely closed by the operation of the indirect hot wire tool 2, and the engaging projection 39 and the engaging hole 49 (not shown) are engaged, so that The edge portion 32 and the other edge portion 42 of the second half cylinder 40 are releasably attached. Subsequently, the gripping member 70 is twisted by the indirect hot wire tool 2, the base end side connecting portion 71 is broken, and the gripping member 70 is removed from the wire cover 10. By attaching the electric wire cover 10 to the electric wire 1 so as to cover the exposed portion 1c, the electric wire 1 is determined in accordance with a predetermined withstand voltage reference (for example, JIS C0920, even in a dry state as well as a watered state). Meet the criteria).

[How to use Example 2]
A method of mounting the wire cover 10 ′ according to the second embodiment on the electric wire 1 (see FIG. 11) including the core wire portion 1 a that is a conductor and the insulating portion 1 b that insulates and coats the core wire portion 1 a will be described. The electric wire 1 has the electrode trace part 1d by which the insulation part 1b was penetrated by the blade-shaped electrode (not shown) of the clamp of a predetermined location.

  Since the method for attaching the wire cover 10 ′ is substantially the same as the method for attaching the wire cover 10 described above, the differences will be described. When the electric wire cover 10 ′ is attached to the electric wire 1, the holding members 80 ′ and 90 ′ are positioned so as to cover the electrode trace portion 1 e. The other mounting process is the same as the process of the mounting method of the wire cover 10. When the wire cover 10 ′ is completely attached to the wire 1, the adhesive members 83 ′ and 93 ′ of the holding members 80 ′ and 90 ′ are adhered to the insulating portion 1 b with the electrode trace 1 e covered. Is done. By attaching the electric wire cover 10 ′ to the electric wire 1, the electric wire 1 satisfies a predetermined withstand voltage standard (for example, a standard defined in JIS C0920) even in a dry state as well as a watered state. Can do.

  The present invention can be applied to an electric wire cover used for an electric wire such as an aerial distribution line constructed to provide a bypass route.
