[Detailed description of the device]

[Purpose of Invention]

[0002]

[Industrial applications]

 The present invention relates to an electric wire protective cover, and more particularly to an electric wire protective cover for protecting an earth electric wire attached to the outer peripheral surface of a column such as an electric pole or preventing contact with the electric wire.

[0003]

[Prior Art]

 Conventionally, this type of electric wire protective cover has a cylindrical shape made of one kind of synthetic resin, or has a structure having a simple opening for inserting an electric wire on the side surface.

[0004]

[Problems to be solved by the device]

 However, as in the above-mentioned conventional method, in the case of the cylindrical wire protective cover, the wire must be inserted in the longitudinal direction of the wire protective cover in advance before disposing the wire, and the mounting workability is poor and If the wire protection cover has an opening in the wire, the wire inserted in the wire protection cover may easily come off and the wire may be exposed.In order to prevent such a risk, open the opening with a stopper after wire insertion. Since it had to be closed, there was a problem with poor installation workability.

The present invention has been made in view of the above-mentioned problems, and the electric wire can be easily attached to the protective cover, and the workability of installation is good, and the electric wire that is once attached is hard to be removed and has high safety. The purpose is to provide a protective cover.

[Constitution of Device]

[0007]

[Means for Solving the Problems]

 According to the present invention, the mounting surface of the elongated cylindrical cover body made of hard synthetic resin that forms the electric wire storage space is an insertion surface part made of soft synthetic resin, and the insertion surface part is the insertion surface part over the entire length along the longitudinal direction. An insertion guide recess is formed on the outer side of the insertion guide recess, and an insertion notch is formed in the insertion guide recess that is inclined with respect to the direction perpendicular to the insertion surface and communicates with the electric wire storage space from the insertion guide recess. It was formed.

[0008]

[Action]

 According to the present invention, an insertion surface portion made of a soft synthetic resin is formed on a cover body made of a hard synthetic resin, and an insertion guide recess formed in the insertion surface portion in the longitudinal direction is used as a guide to guide an electric wire from an insertion notch to a wire storage space. It is not necessary to insert the wire in the longitudinal direction of the wire protection cover before installing the wire, and after installing the wire, the wire can be inserted from the mounting surface of the wire protection cover through the insertion notch on the insertion surface. It can be inserted and the mounting workability is good.

Further, since the cover body exposed to the outside is made of a hard synthetic resin, it can withstand a large impact or load from the outside.

On the other hand, since the insertion surface portion is made of soft synthetic resin, the insertion of the electric wire is easy and the mounting workability is good, and at the same time, after the electric wire is inserted, the insertion notch is automatically closed. Therefore, the inserted electric wire does not come off unexpectedly. Further, since the guide groove for insertion is formed on the outer side of the insertion surface along the insertion notch, the insertion of the electric wire is further facilitated. Furthermore, since the insertion notch is formed to be inclined rather than perpendicular to the insertion surface portion, it is more difficult for the electric wire once inserted to come off the cover body.

【Example】

 Hereinafter, an embodiment of the wire protection cover of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a ground wire protection cover for attaching a ground wire to a utility pole as a wire protection cover. The ground wire protection cover 1 is made of synthetic resin and has a flat mounting surface. It has an elongated cylindrical shape and has an electric wire storage space 2 inside, for example, a length in the longitudinal direction of 2000 mm, a maximum diameter of 19 mm, and a wall thickness of 2 mm. The ground wire protection cover 1 is composed of a cover body 3 and an insertion surface portion 10. The cover body 3 has a curved surface portion 4 having a substantially semicircular cross section and side surface portions 5 extending from both ends of the semicircle. And an elongated tubular shape having an opening over the entire length along the longitudinal direction consisting of engaging projections 6 projecting from both ends of the side surface portion 5 in a direction approaching each other, and made of, for example, hard polyvinyl chloride. Has been done.

An insertion surface portion 10 is formed between the engagement protrusions 6, and the engagement protrusion 6 and the insertion surface portion 10 form a planar mounting surface 8. The insertion surface portion 10 is made of, for example, soft polyvinyl chloride and has an elongated rectangular plate shape. The insertion surface portion 10 has a concave arc-shaped insertion guide recess 12 having a maximum thickness of about 0.5 mm. There is. The insertion guide groove 12 is formed with an insertion kerf 11 which is cut in two in the longitudinal direction.

Note that the insertion groove 11 is formed, for example, in a direction perpendicular to the insertion surface portion 10 in a vertical direction, that is, about 25 degrees from the center direction.

Next, the operation of this embodiment will be described.

According to the ground wire protection cover 1 of this embodiment, since the insertion surface portion 10 is formed, the ground wire protection cover 1 is inserted into the ground wire protection cover 1 in advance before the ground wire is connected to the device or attached to the utility pole. It is not necessary to put it in, and it can be inserted from the insertion notch 11 of the insertion surface portion 10 after connecting or attaching the ground wire. Moreover, in this case, since the insertion surface portion 10 is made of soft polyvinyl chloride, and the insertion recess 12 that serves as a guide for the position when inserting the ground wire is formed, the insertion of the wire is not performed. It is only necessary to push the wire after it has been placed along the guide recess 12 for insertion, and the work of mounting the wire is very easy.

After inserting the ground wire into the electric wire storage space 2, since the insertion surface portion 10 is made of soft polyvinyl chloride, the insertion notch 11 automatically closes and closes, so that it can be used normally. In the state, the ground wire cannot be removed. Further, since the cutting groove 11 for insertion is formed so as to be inclined with respect to the direction perpendicular to the insertion surface portion 10, in the insertion groove 11, the contact between the cross sections of the insertion surface portion 10 becomes large, and the ground wire comes off. It's getting harder.

Further, since the cover body 3 exposed to the outside when the ground wire protection cover 1 is attached to an object to be mounted is made of hard polyvinyl chloride, it can withstand a large impact or load from the outside and protect the ground wire. Can be protected.

Further, since the mounting surface 8 including the insertion surface portion 10 and the engaging projections 6 with respect to the mounted object has a flat shape, the stability when mounted on the mounted object such as a utility pole with a stainless band or the like. I'm getting better.

[Effect of the device]

 According to the electric wire protective cover of the present invention, the electric wire is reliably protected by the cover body made of hard synthetic resin, and at the same time, the electric wire protective cover is made of the soft synthetic resin and has the insertion groove and the insertion guide groove. The electric wire can be easily inserted from the mounting surface of, and the mounting workability can be improved.

Further, since the insertion surface portion is made of soft synthetic resin and the insertion groove is formed so as to be inclined with respect to the direction perpendicular to the insertion surface portion, the electric wire once inserted is hard to come off and the safety is high. ing.
