Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a wire covering device that covers a wire support portion of a spacer.

When multiple electric wires are installed in parallel, especially high-voltage wires, each wire is covered with an insulating sheath to prevent them from coming into contact with each other, and spacers are installed at predetermined intervals to separate and support each wire. ing.

Furthermore, at construction sites, the above-mentioned measures are applied to the electric wires in order to prevent construction machines and the like from coming into contact with the electric wires.

By the way, the electric wire supporting portion of the spacer cannot be covered with a cladding tube, so the electric wire is currently exposed, and there is a risk of contact.

The purpose of this invention is to provide a wire covering device that can easily cover the wire support portion of a spacer, with the above points in mind.

Hereinafter, embodiments of the wire covering device of this invention will be described based on the accompanying drawings.

As shown in FIG. 1, several electric wires 3 such as high-voltage wires are supported on each arm 1 of the spacer A via an insulator 2 such as rubber, and each electric wire 3 is secured to the arm by a pull-out stopper 4. Separation from part 1 is prevented.

The wires 3 on both sides of the arm portion 1 are covered with an insulating cladding tube 5, and the lower part of the cladding tube 5 is a polymer piece 6 that can be opened and closed. Fitted into 3.

An insulating cover B is fitted into each arm portion 1 of the spacer A, as shown in FIGS. 1 to 3.

A fitting hole into which the arm part 1 of the spacer A is inserted is formed in the hollow central part of the covering body B, and a plurality of drain holes 8 are formed at equal intervals in the circumferential direction. An intermediate plate 9 having an inner surface covered with a drain hole 8 is provided apart from the inner surface of the covering body B.

The width of the fitting hole 7 is slightly narrower than the width of the arm portion 1.

The middle plate 9 is made of an elastic insulator such as resin, and has a plurality of protrusions 10 on one side as shown in FIG. 4, and locking claws 11 on both ends, as shown in FIG. , the middle plate 9 is bent and the locking claws 11 are locked with the locking protrusions 12 of the covering body B to attach the middle plate 9 to the covering body B.

This middle plate 9 has a covering body B extending from the electric wire 3 to the drain hole 8.
It plays the role of increasing the insulation creepage distance.

As shown in FIG. 1, an insertion hole 13 into which the cladding tube 5 is inserted is formed at the center of both sides of the cladding body B, and the overlapping piece 6 of the cladding tube 5 extends from the insertion hole 13 toward the outer periphery. An insertion groove 14 for insertion is formed.

The diameter of the insertion hole 13 is smaller than the diameter of the protrusion 15 provided on the cladding tube 5.

In addition, the insertion grooves 14 are provided in correspondence with the number of arm parts 1 of the spacer A, and when the covering body B is fitted into the arm part 1, the cladding tube 5
The overlapping piece 6 is oriented downward.

In the embodiment, since there are four cross-shaped arms 1, four insertion grooves 14 are formed.

A cut 16 extending from the fitting hole 7 to the insertion hole 13 is formed in the lower part of the covering B, and when the arm portion 1 and the sheathing tube 5 are fitted into the covering B, the covering B is cut across the cut 16. After being spread and fitted, the cuts 16 are restored to prevent the sheathing body B from coming off the arm portion 1 and the sheathing tube 5 from coming off from the sheathing body B.

Note that the cuts 16 may be made so that the opposing portions overlap each other as shown in FIG. 3 to prevent rainwater from entering.

As described above, according to the wire covering device of this invention, the covering body can be fitted into the arm portion of the spacer with one touch,
Conventionally exposed areas can be easily covered.

Therefore, this is a very meaningful idea, as it eliminates the fear of accidental contact with electric wires.
