Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cable cover for protecting telephone lines.

[0002]

[Prior Art]

 In recent years, telephone lines and the like have been increasingly installed inside pipes buried in the ground in order to improve the scenery of streets. However, such underground wiring is implemented only in a limited part of the city. Wiring for many telephone lines is still done by pole wiring. Telephone lines, which play a part in the information society, seem to occupy the pillars of the street. It is often seen that three-dimensionally intersecting electric wires are laid near the telephone line. In addition, it is not uncommon for telephone lines to be routed through street trees. Therefore, in order to protect the telephone line, the telephone line is covered with a synthetic resin cable cover (hereinafter simply referred to as a cover). The length of the cover is about 1 to 2 m, and adjacent covers are connected by wire as shown in FIG. 4 to protect the necessary range. The work of covering the telephone line with a cover is performed at a high place. The covers connected by the operator's hands are sent out one after another.

[0003]

[Problems to be solved by the device]

 During the above work, it is necessary to push and pull the cover that has been connected and lengthened, which creates an unnecessary gap between the covers. Due to this gap, branches or other electric wires, which are swept up by strong winds, often damage the telephone line. Even though it is impossible to prevent the formation of gaps, the work is troublesome. First, prepare the connection by twisting it through the hole at the end of the cover and unwinding the wire bent inside the cover. Next, one end of the wire is passed through a hole at the end of another adjacent cover, and both ends of the wire are twisted and bound again. As mentioned above, it is a well-known fact that it is troublesome to handle a wire that has a habit of twisting once.

In order to solve the above-mentioned problems, an object of the present invention is to obtain a cable cover that can be easily worked in a high place and can be connected without a gap.

[0005]

[Means for solving the problem]

 In order to solve the above-mentioned problems, the present invention forms an extension by extending one end of a cable cover made of a synthetic resin tubular body, which is split in the axial direction, in the direction perpendicular to the axis by a predetermined amount and contacting the extension. After extending the other end, the cable cover is extended to the extension portion side in the direction perpendicular to the plate thickness, and further extended by a predetermined amount substantially parallel to the axis perpendicular to the extension portion to cover the extension portion. From the above, a predetermined area is enlarged like a trumpet, and two pairs of holes separated by a certain amount near the enlarged portion are provided at two locations symmetrical to the center line of the tubular body cross section, and can be attached to and detached from the hole. The synthetic resin clip having the device at one end and the projection at the other end is press-inserted into each of the two pairs of holes near the end of the pair of holes and is held rotatably, Also, make two holes near the other end of the tubular body, and There is provided a telephone line protection cable cover, characterized in that the extension portion lacks a predetermined amount cut from the ends of the.

[0006]

[Action]

 The operation of covering the telephone line using the telephone line protection cable cover of the present invention (hereinafter, simply referred to as a cover) will be described below. First, open the cover at the axial split, cover the telephone line, and fit the extension. At this time, the trumpet-shaped enlargement must face the part of the telephone line that requires protection. Push the first cover in that direction. Set the next cover on the telephone line as well as the first cover. Overlap the trumpet-shaped enlarged part of the second cover on the rear part of the first cover, remove the detachable device of the clip of the second cover from the hole, and insert and fix it in the hole on the rear part of the first cover. Then, for the third cover, the connected cover is pushed out in the pushing direction. Continue to do the same until you have covered the areas that require telephone line protection.

When the cover is not actually used, two protrusions at both ends of the clip and the detachable device are inserted into a pair of holes and temporarily fixed. Therefore, regarding the packaging form, it is sufficient to consider only the length of the tubular body, and there is no tendency for the clip to deform during transportation.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view and a side view of a tubular body of a cable cover according to an embodiment of the present invention. One end of the extruded synthetic resin tubular body 1 is heated, embossed, and cooled to form a trumpet-shaped enlarged portion 2. At the lower part of the tubular body 1, there is an extension part 3 formed in an axially split part, and the extension part 3 is notched at the other end to form a notch part 4. The tubular body 1 is provided with two pairs of holes 5a and 5b near the enlarged portion, and another pair of holes 51a and 51b (not shown) are provided at symmetrical positions with respect to the center C of the cross section. Has been. Further, a hole 6 is provided at an end portion on the side opposite to the enlarged portion 2 at substantially the same height as the pair of holes 5a and 5b, and the hole 61 (not shown) is provided at a symmetrical position with respect to the center C of the cross section. ) Is provided. FIG. 2 is a partial front view of the cable cover according to the embodiment of the present invention when a clip is attached to the tubular body. The projecting portion 7a of the clip 7 is inserted into the hole 5a, and the detachable device 7b is inserted into the hole 5b. FIG. 3 shows a partial front view and a sectional view when the cable cover of the embodiment of the present invention is attached to a telephone line. Telephone line 9 is supported by telephone line support cable 8.

In the above embodiment, the material of the tubular body 1 is linear polyethylene (Yukaron, UE320 manufactured by Mitsubishi Petrochemical Co., Ltd.), but other polyethylene may be used without any problem. A commercially available product (manufactured by Nifco Co., Ltd.) is used as the clip, and the detachable device is a combination of a plunger 2009 and a grommet 2001, and further a combination of plaster rivets 0033-1-10-110-02. Has been done.
