Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device used for anchoring a service line from a distribution line to a customer.

[Prior Art] This type of wire support has mounting parts that can be attached to utility poles, houses, etc. on the wire support main body, which is an integrally insulated molded product, and mounting parts on the left and right sides of the wire support main body. This is a structure in which a group of wire support grooves for retaining and supporting the drawn-in wires are arranged in parallel. Some of the above-mentioned mounting parts have a hanging metal fitting structure.

The present applicant has proposed electric wire supports equipped with hanging metal fittings as
No. 40733, No. 40734, etc. are provided.

By the way, when attaching a conventional electric wire support to a utility pole, a belt or a band wound around the utility pole is inserted through a hanging metal fitting. After that,
Attach a belt or band to either the top or bottom of the utility pole at the above-mentioned attachment point, hook the hook of the wire tensioner to this, attach the wire tensioner, and then tighten the wire with the wire clamped to this wire tensioner. Ta. That is, no wire tensioning machine was attached to the wire support.

[Problem to be solved by the invention] According to the above-mentioned wire tensioning work, the wire support and the wire are not located on the same line, but are phased either above or below, so it is difficult to pull the wire into the wire support groove. Difficult to work with. In other words, since the wire support and the wire are separated from each other to an extent that does not interfere with the wire tensioning work, it is necessary to change the direction of the wire support main body while performing the pulling work to make it easier to insert the wire end into the wire support groove. First, these operations had to be carried out on pillars, etc.

Moreover, since they are installed in a phased state, there is a drawback that loosening is unavoidable due to the phased state after installation.

Furthermore, there are cases where the wire is pulled in from the house side, but in this case, there is no place to hook the hook of the wire tensioner, so it cannot be used.

Furthermore, if the wire is large in diameter, it is difficult to reliably draw it in, so most wires must have three wire support grooves on each side, which has the disadvantage of increasing the overall size. . If a hole structure was used to avoid an increase in size, the work of pulling the pillar into the hole on the pillar would be troublesome.

Therefore, the present invention was devised to eliminate the above drawbacks, and its main purpose is to enable wire tensioning work to be easily and accurately performed on the same line using a wire tensioning machine. That is.

[Means for Solving the Problems] A feature of the wire support according to the present invention for achieving the above object is that four wire support groove groups are formed to a size that allows large diameter wires to be drawn into the wire support. Thick arm parts and retaining collars are formed on the left and right sides of the upper and lower intermediate parts of the main body, respectively. Between the retaining collars of the arm parts, recesses that gradually become thicker to the left and right outwards are provided, respectively, to support electric wires. The central lower part of the tool body is characterized by being wider toward the lower part and formed into a large curved surface at the lower wide part.

[Function] The wire support is attached to a member to be attached, such as a telephone pole or a house, via the attachment part. After that, insert the hook of the wire tensioner from the lower wide part of the attachment hole for the wire tensioner located at the lower center of the wire support body, and lock the hook while positioning it along the curved surface of the wide width. .

When the wire tensioning machine is attached, the wires to be drawn in will be positioned on the same line at the center of the wire support body. Therefore, the wire tensioning machine is operated to set the wire and the wire support to a predetermined tension, and the wire is pulled into the wire support grooves on the left and right sides of the wire support body.

After a large-diameter wire passes through a wire support groove, it is bent greatly by a thick arm and is bitten into a recess to be held in place, while a small-diameter wire is bent toward the center by the slope of the recess. It is sent. Both electric wires are restrained by a retaining collar and are held in tension close to the same line.

[Example] The drawings show an example of the wire support according to the present invention, FIG. 1 is a perspective view showing the installed state, FIG. 2 is a front view of the wire support, and FIG. 3 is a side view of the same. FIG. 4 is a bottom view of the same, FIG. 5 is a sectional view of the wire support main body along line A-A in FIG. 2, and FIG. 6 is a cross-sectional view of the wire support main body along line B-B in FIG. Figure 7 is a sectional view illustrating the drawing state of the large diameter electric wire in the line C-C line in Fig. 2, and Fig. 8 is a sectional view explaining the drawing condition of the small diameter electric wire in the line C-C line in Fig. 2. FIG.

The wire support 1 is made of an insulating material such as BMC or SMC, and has a wire support main body (hereinafter referred to as the main body).
2 is integrally molded, a hanging fitting 4 as a mounting part is attached to the elongated hole 3 at the center of the upper part of the main body 2, and wire support groove groups 5 to 8 are arranged in parallel on the left and right sides of the main body 2. There is. A mounting hole 9 for a wire tensioning machine is provided at the lower center of the main body 2. The wire tensioning machine attachment hole 9 is formed into an elongated hole that becomes wider downward as shown in the figure.

To be more specific, the wire support groove groups 5 to 8 are arranged symmetrically in the left and right sides of the main body 2 and are arranged vertically in four pieces.
Each is formed into a substantially C-shape with openings on the left and right sides. The wire support groove groups 5 to 8 are large enough to allow the large diameter electric wire 30 to be drawn in, and the upper and lower circumferential surfaces of each groove are curved toward the front and back to enlarge the contact area, as shown in FIGS. 2 and 4. Mooring portions 10 to 17 are formed for mooring and guiding.

Furthermore, thick arm portions 18 and 19 are constructed on the left and right sides of the upper and lower middle portions of the main body 2, as shown in FIG.
As shown in Fig. 4, the retaining collars 20, 21 and 2
Recesses 24 and 25 are formed between 2 and 23. The recesses 24 and 25 are formed to gradually become thicker toward the outside.

Further, reference numerals 26 and 27 in the figure are collars for preventing slippage on the retraction side. Note that 28 is a curved surface portion around the wire tensioning machine attachment hole 9. The curved surface portion 28 is formed into a large curved surface at the lower wide portion of the wire tensioning machine attachment hole 9, as shown in the figure.

When using the electric wire support 1, for example, a fastener 3 attached to a house 32 as a member to be attached.
3, the hook 36 of the wire tensioner 35 with the electric wire 30 or 31 attached thereto is inserted into the wire tensioner attachment hole 9. The hook 36 is easily inserted along the lower width shape of the wire tensioning machine mounting hole 9,
It matches the curved surface portion 28 and is locked. In this state, operate the lever 37 of the wire tensioner 35 to perform the desired tensioning, and then insert the wire ends into the left and right wire support grooves 5.
Or insert it from the introduction side of 7 and perform the retention.

When the wire 30 has a large diameter, it is bent and meandered through the wire support groove 5 or 7 to 6 or 8, as shown in FIG. In this case, the arm 18 or 1
9, it is bent greatly, and at the same time it bites into the narrow bottom of the recess 24 or 25, generating a sufficient retaining force.

If the electric wire 31 has a small diameter, it may be wound around the arm portion 18 or 19 and then led out, as shown in FIG. In this case, the wound wire 31 is brought as close to the inside as possible by the curvature of the recess 24 or 25, and the initial winding point is further bitten into the bottom of the recess 24 or 25.

In the above embodiment, the hanging metal fitting 4 is illustrated and explained as the attachment part, but the intention is not limited thereto, and the electric wire has a fixing structure using bolts or the like, or an attachment part of the attachment structure using a belt or the like. It is also applicable to supports.

[Effects of the invention] As explained above, the invention provides the following effects.

The wire support, the wire tensioner, and the wire can be mounted on the same line on the pole, and the drawbacks of conventional phasing etc. can be eliminated.

The hook of the wire tensioner can be easily inserted into the wire tensioner mounting hole of the wire support body from the wide part at the bottom of the center, and even if the hook dimensions differ depending on the manufacturer, the wide part This made it extremely easy to attach the wire tensioner to the wire support on the pole. Moreover, after the hook is engaged, the hook can fit into the large curved surface and be easily engaged.

Large-diameter electric wires can be bent greatly by the thickness of the left and right arms of the main body and then inserted into the recess, so that the large-diameter electric wires can be reliably supported on the same line of the wire support without loosening during tensioning. This made it possible to create two wire support grooves on each side, making it more compact than before.

Since the concave part of the arm is thick and slopes outward, a large-diameter wire can be inserted into the bottom of the center of the main body, and a small-diameter wire can be wound around the bottom of the center of the main body, and then secured with a retaining collar. Therefore, during tensioning, the wire can be securely tied to the center of the main body along the same line as much as possible.
