Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire cover for covering an electric wire, particularly a high-voltage wire, during an electric wire construction or a construction near the electric wire.

[0002]

2. Description of the Related Art Conventionally, the wire cover shown in FIG. 3 has been known. The electric wire cover 30 is made of plastic such as polyethylene and has a tubular body 3
1 and a pair of legs 41, 41 formed in the longitudinal direction on the side surface 32 of the main body 31. The main body 31 has overlapping end portions 33 and 34, one on the outer side and the other on the inner side, which are overlapped with each other and are formed in the longitudinal direction of the side surface. The legs 41, 41 are formed in a thin plate shape on the outer surface of the outer overlapping end portion 33 of the main body and on the outer surface near the inner overlapping end portion 34.

When the electric wire cover 30 is attached to an electric wire, as shown in FIG. 4, the space between the legs 41 and 41 is widened, so that the outer overlapping end portion 33 and the inner overlapping end portion 34 are formed. The electric wire C is accommodated in the main body 31 through the gap 35. After that, except for the force to spread the legs 41, 41,
The main body 31 is elastically restored, and the inner overlapping end portion 34 overlaps the inner surface of the outer overlapping end portion 33 to close the gap 35, thereby completely hiding the electric wire inside.

However, in the electric wire cover having the above structure, the inner overlapping end portion 34 has the outer overlapping end portion 33.
Since it has a structure overlapping with the inner surface of the wire, the gap 35 cannot be made sufficiently large and cannot be attached to or detached from the electric wire unless the legs 41, 41 are widened at the time of attaching or detaching to the electric wire. Moreover, the electric wire cover body 31 is compliant with JIS A from the viewpoint of shape retention.
Since it is made of a hard plastic having a hardness (rubber hardness meter) of about 90 degrees, it was not easy to open the legs 41, 41 largely.

Further, when attaching / detaching to / from the electric wire, the legs 41, 4
When the electric wire is stored in the main body 31 or the electric wire is removed from the main body 31 without sufficiently opening the space between them, the coating of the electric wire may come into contact with the inner overlapping end portion 34 and be rubbed and damaged. It was

SUMMARY OF THE INVENTION Therefore, the present invention
An object of the present invention is to provide an electric wire cover that is easily attached to and detached from an electric wire, and that does not damage the coating of the electric wire when the electric wire is attached and detached.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a tubular main body having overlapping end portions, one of which is an outer side and the other of which is an inner side thereof, and which overlap each other in a longitudinal direction of a side surface, and the outer superposing body of the main body. In the electric wire cover, which is composed of a pair of legs formed on the outer surface of the end portion and the outer surface near the inner overlapping end portion, and in which the space between the legs can be opened and closed, the inner overlapping end portion is larger than other portions of the main body. Is also made of a soft material.

[0008]

In the electric wire cover of the present invention, the inner overlapping end of the body is made of a softer material than the other parts of the body. Therefore, when attaching / detaching to / from the electric wire, there is little opening between the legs, and even if the electric wire hits a part of the inner overlapping end, the inner overlapping end is bent by being pushed by the electric wire,
Allows the storage of electric wires in the main body and the removal of electric wires from the main body. Moreover, at that time, since the inner overlapping end portion is soft, there is no fear of damaging the coating of the electric wire. Furthermore, after the electric wire cover of the present invention is attached to the electric wire, the soft inner overlapping end portion is deformed because the soft inner overlapping end portion is held by the hard outer overlapping end portion overlapping the outer surface thereof. The wires will not come off the main body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view of an embodiment of an electric wire cover of the present invention, and FIG. 2 is a cross-sectional view for explaining mounting of the electric wire cover on an electric wire.

The electric wire cover 10 shown in FIGS. 1 and 2 is
It consists of a plastic body 11 and legs 21 and 21.
The main body 11 is formed of a tubular body in which side surfaces 12 are formed with overlapping end portions 13 and 14 in the longitudinal direction. One of the overlapping end portions 13 constitutes an outer overlapping end portion and the other overlapping end portion 14 constitutes an inner overlapping end portion, and both overlapping end portions 13 and 14 are overlapped by a predetermined width so as to be openable and closable. There is. The overlap margin is about 10 to 17 mm when the inner diameter of the main body 11 is about 38 mm.

The inner overlapping end 14 is formed by the main body 11
Made of softer material than other parts. As a result, the inner overlapping end portion 14 bends at the time of attachment / detachment to / from the electric wire to facilitate its attachment / detachment, and even if it comes into contact with the coating of the electric wire, the coating is not damaged.

The hardness of the body 11 is such that the inner overlapping end portion 1
No. 4 is about 60 to 75 degrees according to JIS A (rubber hardness meter) and about 90 degrees on the other part of the main body 11 with the same hardness meter.
It is preferable in that the shape retention of the electric wire cover 10 is not impaired and the electric wire cover 10 can be easily attached to and detached from the electric wire. The thickness of the main body 11 depends on the type of plastic, but is usually 2.1 to 2.
It is about 4 mm. The material of the main body 11 is an appropriate plastic, but an example in which the inner overlapping end portion 14 is made of an olefinic elastomer or EVA resin having the above hardness and the other portion is made of polyethylene having the above hardness is shown as an example. .

The legs 21, 21 have outer lapped end portions 13
The outer surface and the outer surface near the inner overlapping end portion 14 are formed in a thin plate shape in the longitudinal direction and integrally with the main body 11, and are made of the same material as that of the main body 11 portion excluding the inner overlapping end portion 14. When the electric wire cover 10 is attached to and detached from the electric wire, the legs 21 and 21 are grasped by an operator to facilitate opening between the outer overlapping end portion 13 and the inner overlapping end portion 14. Further, after covering the electric wire with the electric wire cover, the legs 21 and 21 are overlapped and securely closed by a clip (not shown) or the like to prevent the electric wire from coming off the electric wire.

As shown in FIG. 2, the electric wire cover 10 thus formed has a predetermined distance between the legs 21 and 21, and the electric wire C is pushed into the main body 11 from between the legs 21 and 21. At that time, even if there is not a sufficient gap between the inner overlapping end portion 14 and the outer overlapping end portion 13 or there is some overlap, the inner overlapping end portion 14 is pushed by the electric wire and So that it can be bent inward to help accommodate the wires in the body 11. Further, at that time, even if the coating of the electric wire comes into contact with the inner overlapping end portion 14 and is rubbed, the inner overlapping end portion 14 is soft, so that there is no fear of damaging the coating.

After the wires are accommodated, if the force for opening the legs 21 and 21 is removed, the elasticity of the main body 11 restores it as shown in FIG. 1, and the inner overlapping end 14 overlaps the inner surface of the outer overlapping end 13. The legs 21 and 21 are closed.

When removing the wire cover 10 from the wire, the legs 21 and 21 are opened again, and the wire is removed from between the legs 21 and 21. At that time, the inner overlapping end portion 14 of the main body
Even if there is not a sufficient gap between the outer overlapping end portion 13 and
The inner end 14 is pushed by the wire and bends outwards to help release it from the wire. Moreover, even if the coating of the electric wire is rubbed by the inner overlapping end portion 14, there is no possibility of damaging the coating of the electric wire as described above.

[0017]

As shown and described above, according to the electric wire cover of the present invention, it is easy to attach to and detach from the electric wire, and work in high places becomes simple and safe. Moreover, since there is no risk of damage to the wire cover even if the wire cover is rubbed against a part of the wire cover during installation and removal, the work becomes easier and safer, and the repair of the wire due to the damage is also unnecessary. is there.
