Description

[0001] The present invention relates to a bar structure for fixing electric lines,

[0001] The present invention relates to a wired iron structure for fixing a distribution cable of a telephone pole, and more particularly, to a wedge structure for fixing a wire to a power distribution line, The present invention relates to a wired iron structure for fixing a distribution cable to a pole of a telephone pole, which can easily change the position of a distribution line and can absorb a shock caused by a strong wind or the like.

Generally, a large power generated by a power plant is transmitted to each substation at a high voltage through a power transmission line such as a power transmission tower, and then transformed at various stages in a substation so that a cable can be used for each household or building.

In general, a high-voltage transmission cable, that is, a processing distribution line is coated with an aluminum spiral bundle and a synthetic resin covering layer covering the outer periphery thereof, and it is connected to a telephone pole to supply electricity to each customer from a power plant or a substation .

In this case, when a processing distribution line is installed in the mainsheet, a conventional insulator is installed in order to block the sag due to the load and the electrical contact with the bare iron. In order to reduce stress concentrated on the processing distribution line and to prevent disconnection of the processing distribution line In addition, since the birds are easily accessible to the above-mentioned brass bars, the parts and the processing power distribution lines are easily damaged by the algae, so that maintenance and repair costs are high.

However, this technique can not completely block the approach itself because the periodic rotating protrusion rotates only in a fixed path, so the bird can adapt itself over time, and when the tension of the wire due to wind changes, There is a risk that there is still a risk of disconnection at the time of contraction and expansion.

In addition, in the case of the "fixing insulator for supporting a transmission work line" described in Japanese Patent Registration No. 116,1001, a pressing block or the like including a complex fitting such as a connecting port and a fastener is required to be attached to the insulator on the insulator There is, of course, a lack of additional cushioning capability, which implies a very high risk of breakage if only a slight impact is applied.

Fig. 10 is a cross-sectional view showing the internal structure of the strut, and Fig. 11 is an exploded perspective view of Fig. 10, and the same reference numerals are given to the same components as those of the previously described embodiment, and detailed description thereof is omitted.

As shown in these drawings, the present invention comprises first and second slide pieces 120A and 120B mounted on the outside of the above-mentioned support 100, and a second slide piece 120B disposed inside the support 100, And an elastic member 130 closely attached to the outer circumferential surfaces of the first and second slide pieces 120A and 120B and a binding housing 140 and a clamp 150 for fixing the processing power distribution line L. [

That is, the first and second slide pieces 120A and 120B are formed into discs having different diameters by the steps 121 and are assembled by being inserted into the slots 110 formed at the upper and lower ends of the support 100, And can slide in the horizontal direction.

In the case of the elongated hole 110, a step 111 is formed so as to match the outer shape of the first and second slide pieces 120A and 120B. On the lower side of the support base 100, A flat plate member 112 having a through hole 112a is integrally formed.

The elastic member 130 includes a hemispherical support piece 131 disposed in the horizontal direction of the first and second slide pieces 120A and 120B and a spring 132 fixedly secured to the hemispherical support piece 131, And a fixing piece 134 mounted in the support base 100 to support a repulsive force of the spring 132 due to an external force applied to the hemispherical support piece 131. [

The coupling housing 140 includes a cylindrical cap 141a and a blade piece 141b extending to both sides of the cylindrical cap 141a and the bolt 142 is inserted into the through hole 142a formed in the cylindrical cap 141a.
