Description

[Detailed description of the invention] Purpose of the invention [Field of industrial application] The present invention relates to a cable protection cover suitable for various cables such as electric wire cables, steel wire cables, and optical fiber cables, especially parallel cables.

[Conventional technology]

Covers for protecting various types of cables, including electric wire cables, have been known for example, such as those covered with a paint film, those covered with grout, and those covered with a plastic cover.

[Problem that the invention attempts to solve]

However, all of these have short service life, require relatively large maintenance costs, and have poor appearance.

The present invention eliminates the drawbacks of conventional products as described above, and combines two long semi-tubular members of the same shape and size to form a polygonal tube structure, making the cable more efficient. The present invention provides a cable protection cover that is adapted to be accommodated in a cable.

Structure of the invention [Means for solving the problems] The present invention was made to solve the above problems.
A cable protection cover that contacts the outer surface of a cable in which a plurality of single wires having substantially the same outer diameter are arranged in close contact with each other so that the cross section thereof forms a substantially regular hexagonal shape, and stores the cable in a substantially regular hexagonal shape. The cable protection cover has two semi-tubular members having the same shape and size, each having a plurality of flat surfaces on the inside and rounded corners formed by the two semi-tubular members on both sides thereof. The semi-tubular member has a substantially regular hexagonal inner wall that is connected to each other in the longitudinal direction and circumscribes the outer surface of the cable; Each of the engaging portions is provided with a protrusion extending outward from the inner wall of the semi-tubular member and parallel to the inner wall in the longitudinal direction, and the other engaging portion is provided with a protrusion extending longitudinally in parallel with the inner wall of the semi-tubular member. Each of the members has grooves arranged on the outside of the inner wall in the longitudinal direction in parallel with the inner wall, and the protrusions and the grooves are connected to each other in the longitudinal direction of both edges of the semi-tubular member. The gist of this invention is a cable protection cover that is characterized by being press-fitted.

For example, sawtooth-like peaks may be provided on the side walls of the protrusions and grooves.

[Effect]

The cable protection cover of the present invention has a substantially regular hexagonal shape by press-fitting and joining protrusions and grooves provided on thick engagement parts protruding outward from the outer wall of the semi-tubular material on both side edges thereof. It has an eggplant inner wall.

Therefore, a plurality of single wires having substantially the same outer diameter are brought into close contact with each other so as to circumscribe the outer surface of the cable arranged so that the cross section thereof has a substantially regular hexagonal shape, and the cable is suitably accommodated while retaining its shape.

〔Example〕

Hereinafter, the cable protection cover of the present invention will be explained based on the drawings.

FIG. 1 is a side view of one embodiment of the cable protection cover of the present invention, and FIG. 2 is a longitudinal cross-sectional view corresponding to FIG. 1. In each figure, 1 is a semi-tubular member of the same shape and size made of aluminum, copper, titanium, or an alloy thereof, natural or synthetic rubber, or hard plastic, and the inner wall has a plurality of flat surfaces 1a, 1b...1f. Equipped with
The corners 3a...3h formed by these surfaces have curved surfaces approximately equal to the radius r of the single wire 5, as shown. A protrusion 2 is provided in the longitudinal direction on one side of the thick engaging portion that protrudes outward from the outer wall of the side edge of the semi-tubular member 1.
is provided, and the other engaging portion is provided with a groove 4 that can fit into the protrusion 2. The semi-tubular members 1 are press-fitted facing each other in the longitudinal direction of both side edges to form a polygonal tube whose cross section is, for example, a hexagon as shown in the figure, and a single wire of the same outer diameter. 5 are circumscribed and shape-retainingly housed in cables arranged so that their cross sections form a substantially regular hexagonal shape. Since the cross section is approximately regular hexagonal, the number of cables that can be stored is 7, 19, 37, 61, 91,
It will be one of 127... In either case, the inner wall tightly circumscribes the cable. Note that it is preferable that the protrusions 2 and the grooves 4 be provided with opposing serrated peaks as shown in FIG. 2 to prevent them from coming off. In addition, as in another embodiment shown in FIG.
If a groove 6 having a curved surface approximately equal to the radius r of the single wire 5 is provided around the inner wall surface of the single wire 5, the single wire 5 can be stored more stably. Note that the circumscription of the engaging portion with the single wire 5 is not limited to the substantially regular hexagonal corner portions as shown in FIGS. 2 and 3. For example, as in another embodiment shown in FIG. 4, the engaging portion may be configured to circumscribe the single wire 5 forming one side of a substantially regular hexagonal shape.

As described above, in this embodiment, two semi-tubular members having the same shape and size are press-fitted into each other with protrusions and grooves provided on the engaging portions protruding outward from both side edges. By joining, an inner wall having a substantially regular hexagonal shape is realized. Therefore, the following effects are achieved.

(1) The engaging part of the cable protection cover protrudes outward and there are no protrusions inside. Therefore, the inner wall of the cable protection cover has a substantially regular hexagonal shape.
Cables with a high degree of integration can be housed in a shape-retaining manner by closely aligning single wires with the same outer diameter in a substantially regular hexagonal shape.

(2) Furthermore, since the engaging portion of the cable protection cover does not protrude inward, it does not put pressure on the single wires that make up the cable. Therefore, bending and damage of the single wire can be prevented.

(3) Since both engaging portions of the cable protection cover protrude to the outside, the cable protection cover can be easily grasped and fixed.

(4) Can be used as a cable protection material during cable installation work or on the spot after installation.

(5) A polygonal tube body can be easily formed by press-fitting semi-tubular materials of the same shape and size facing each other.

(6) Since the joining is done by the protrusions and grooves,
The two semi-tubular members are difficult to separate.

(7) Made of aluminum, lead, titanium, other alloy metals, or hard plastic molded products, it has excellent corrosion resistance, weather resistance, and long life, and is a cable protection cover for cable bundles, etc., used outdoors, underground, or underwater. It is most suitable as

Effects of the Invention As detailed above, the cable protection cover of the present invention increases the efficiency of accommodating cables made of solid wires arranged in a substantially regular hexagonal cross section, and prevents bending and damage of the single wires that make up the cables. It has excellent effects.
