Description

[Detailed Description of the Invention] The present invention relates to a wire support that is attached to a utility pole with a utility pole band.

2. Description of the Related Art A wire support device is known in which a vertically long support body is provided with several wire receiving grooves arranged in vertical rows. However, since conventional products are entirely molded from synthetic resin, they are susceptible to external changes such as temperature and ultraviolet rays, and there is a risk of cracking or breaking during use.

The present invention aims to eliminate the drawbacks of the above-mentioned conventional products and provide a durable wire support.

To explain the drawings, 1 is a vertically long base formed by bending a steel plate into a U-shape, with the U-shaped bottom 1b facing the utility pole, and the U-shaped legs 1a, 1a.
Electric pole 1 extended in a roughly “V” shape at the open end of the
c, 1c are formed. 2 is its both leg sides 1a, 1a
A plurality of electric wire receiver fitting grooves 4 are provided at the base of the U-shaped bottom side of the leg sides 1a and 1a of the base 1, and grooves 5 are provided at the opening side of the leg sides. This is a telephone pole band through hole. 10 and 11 are positioning protrusions of the wire receiver 3. Reference numeral 3 denotes a wire holder made of electrical insulator inserted into the fitting groove 2 of both leg sides 1a, 1a of the base 1 from the opening side of both leg sides, and protrusions 3c, 3b provided on the outer periphery 3 surface It is locked to the outer surface of 1a to form a retainer. 3a is wire receiver 3
A wire receiving groove is provided with an opening on the opening side of the leg side 1a, and the groove surface is shaped like a drum as shown in FIG. 9 to prevent damage to the insulation coating of the wire due to rubbing. 3d is a binding wire passing hole provided at the deep bottom of the wire receiving groove 3a. This wire holder 3 is made of synthetic resin, reinforced plastic, porcelain, or the like. Reference numeral 6 indicates a rivet that fixes the wire receiver 3 to the base 1, but this fixing means may be a bolt, nut, adhesive, or the like.

The drawing shows an example in which the wire receiver fitting groove 2 provided on the base 1 and the wire receiver groove 3a of the wire receiver 3 are formed into front upward diagonal grooves to prevent the wire from coming off in the horizontal direction. If the receiving groove 3a is made into a bent groove as shown in FIG. 10, the wire receiving tool 3 may be attached to the base 1 horizontally.

In Figure 1, the concave bottom side 1b of the base 1 is placed on the telephone pole P,
Pass the known utility pole band 7 through the hole 4, attach the base 1 to the utility pole P, hang the electric wire 8 through the groove 3a of the electric wire holder 3, pass the binding wire 9 through the hole 3d, and attach the electric wire 8.
As shown in Fig. 2, the present invention is used for wiring through holes by binding.

When using the present invention to tie down electric wires, as shown in Fig. 3, the leg sides 1a of the base 1, the electric wire contact surface 1c on the open side of 1a are placed on the utility pole P, the utility pole band 7 is passed through the hole 5, and the wire is attached to the utility pole. Pass the electric wire 8 through the groove 3a and the fourth
Fasten as shown.

Conventionally, this type of wire support is integrally molded from synthetic resin and firmly fixed to the pole with two or three pole bands, so the bands are constantly subject to locally concentrated stress, and the synthetic resin is subject to temperature fluctuations. Because of the deterioration caused by such factors, a one-piece block is likely to crack or break in parts, and has the disadvantage of requiring constant maintenance, inspection, and replacement. However, as described above, the present invention consists of a steel plate base 1 having a U-shaped cross section, and a receiver 3 made of an electrical insulator that is fitted and locked in the wire receiver fitting groove 2, and the steel plate base 1 is attached to a utility pole with a utility pole band, the steel plate base receives the local load from the utility pole band, and the insulator holder is in a relationship similar to an insulator, so there is less damage caused by external influences, and the It has the effect of providing durability.
