When snow adheres to power transmission lines during snowfall, the load on the lines increases, so this must be taken into account when designing the strength of the support structures. In addition, if there is significant snow accumulation, it can lead to serious accidents such as collapse of supports.
Snow that has adhered to the wires may fall off due to rising temperatures, increased power transmission currents, vibrations caused by wind, etc., and can cause serious damage to above-ground structures, crops, and human reserves. Snow accretion on power transmission lines must be prevented as much as possible.

Therefore, snow accretion must be avoided as much as possible on spacers, etc. that constitute part of power transmission lines;
In order to prevent snow from adhering to the conductive spacer, it is first necessary to minimize the projected area in the direction in which snow flies and to eliminate surface irregularities. Since the flying direction of snow is mainly in the upward direction, it is necessary to reduce the projected area of the two-conductor spacer from the upward direction, that is, to reduce the width of each part of the spacer when viewed from the upward direction. The part of the spacer where the width tends to increase is the wire gripping part, and if the wire gripping part does not use bolts for tightening but uses spring force, the size and arrangement of the tightening springs should be adjusted to reduce the width of the gripping part. I have to reconsider the direction.

Some conventional spring-type electric wire gripping parts have a structure in which two springs (coil springs) are arranged horizontally side by side, which inevitably results in a wide width. Therefore,
To narrow the width, replace the spring that was split into two with one spring.
It is necessary to make it into a book and keep the spring storage section compact.

い。
However, when looking only at springs, if two springs are simply combined into one, the wire diameter needs to be considerably larger to obtain the same spring force, and from the standpoint of spring manufacturing and prevention of stress concentration, Since the value of [coil diameter/wire diameter] of the spring must generally be 3 or more, when the wire diameter is increased, the coil diameter also becomes considerably large. Therefore, it is unavoidable that the width of the spring and the spring storage portion become relatively large.

This idea was made in consideration of the above,
In order to provide a wire gripping part of a spacer with a relatively small width when viewed from the top and bottom, two large and small springs are fitted concentrically to each other and combined in parallel, and the wire diameter of each spring is reduced. The above object is achieved by reducing the coil diameter and thereby reducing the width of the spring housing. In addition, the spring housing needs to have sufficient strength to withstand the load when the spring is precompressed and various loads when the wire vibrates, but in the conventional form, a relatively large wall thickness was required to obtain this strength. However, the outside width of the spring housing section had the drawback of becoming wider accordingly. In order to reduce this thickness,
This invention is characterized in that the spring housing section is formed with a cylindrical wall surrounding the coil spring, thereby making it possible to reduce the thickness of the wall.

As shown in the figure, the wire grip main body 1 has one end pivotally connected to one end of a spacer S by a pin 2, and a presser 3 hingedly connected to the other end by a hinge pin 4. The hinge pin 4 is located at the upper end of the presser 3, and the lower end of the presser 3 is adapted to engage with the T-shaped end of the T-clevis 5, as shown on the right side in FIG. 2 and in FIG. The other end of the T clevis 5 is pivotally connected to the eye-shaped end of an eye bolt 7 by a pin 6, and the eye bolt 7 extends through a part of the main body 1, and a nut 8 is screwed onto the threaded end of the eye bolt 7. 8 holds down washer 9. There are two large and small coil springs 10 and 11 arranged concentrically and in parallel around the eyebolt 7. The coil springs 10 and 11 are compressed between the washer 9 and the main body, and are made of a thin cylindrical wall 12. A cylindrical spring storage portion 13 integrally formed with 1.
It is stored inside. The spring storage portion 13 is closed by a screwed cap 14, and a set screw 15 is mounted on the cap 14 so as to be screwed into the cap and capable of pushing the end of the eye bolt 7.

When loosened, the force of the springs 10 and 11 moves the eyebolt 7 to the right in FIG. 3 via the washer 9, and the end (lower end) of the presser 3 is pulled toward the grip body.

According to this invention, the springs for obtaining the wire gripping force are two coiled springs of different sizes and used concentrically in parallel, so the coil diameter is relatively small and a large force can be produced. Therefore, the spring storage portion can also be made small, and since it is approximately cylindrical, it can be made relatively thin and lightweight. The diameter of the coil spring is small, so the spring storage part is also small, and the projected area of the grip main body in the vertical direction can be reduced, which reduces the amount of snow that accumulates and has the effect of reducing damage caused by snow.
