Description

[Detailed Description of the Invention] The present invention relates to an improvement of an electric wire holding fitting used for branching, connecting, etc. of overhead electric wires.

As shown in FIG. 1, FIG. 2, and FIG. 3, the conventional electric wire attachment fitting 1 is constructed by loosely fitting an electric wire attachment ring 4 having a side groove 3 on the outer periphery into the bent part of the U fitting 2. Hole 5 drilled at the tip
, 5 is removed, and the wire attachment ring 4 is inserted and installed.Then, the retaining clamp 8 of the high-voltage tension insulator T is positioned between the holes 5 and 5 of the U bracket 2, and the bolt 6 is removed. They are connected and fixed by inserting a split pin 9 into the tip of the bolt 6.

Generally, two high-voltage tension insulators 7 are connected in parallel as shown in FIG.
be installed on.

Then, the electric wire 13 is wound and attached to the electric wire attachment ring 4 of the hold-down fitting 1 located at the tip, and the electric wire is fixedly installed. Attach the electric wire to the arm 12 by pulling it with a wire, etc., and then lift the high-voltage tension insulator 7 and the retaining fitting 1, which are hanging down under their own weight as shown in FIG. The wire 13 that had been attached to the wire was removed and wound around the wire attachment ring 4 of the hold-down fitting 1.

Since all of this work is done at high places, there is always danger involved in lifting the high-voltage insulators 7, etc., removing the electric wires 13 from the arms 12, and moving the body from place to place, and there is a strong desire to improve this situation. Ta.

Therefore, in this invention, a long hole for locking the hook rod is provided in the U fitting of the hold-down fitting, and the hook rod is removably fitted into the long hole, and the electric wire is temporarily fixed to the hook rod, thereby making it possible to work on the pole. It is designed to be done easily and quickly.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 4 and 5 show a wire retaining fitting according to the present invention, in which elongated holes 15 and 15a are formed at approximately the center of both the left and right sides of the U fitting 2 and are slightly shifted from each other, through which the hook rod 14 is inserted and locked. Set up

The hook rod 14 has a straight portion located between the left and right sides of the U metal fitting 2, a tip 14a bent at a substantially right angle, and a wire locking portion 16 bent into a hook shape at the other end. 15°15
a and fix it to the U bracket 2.

When the hook rod 14 hooks the electric wire 13 etc., the wire locking portion 16 is pulled toward the wire attachment ring 4 side, and the hook rod 14 is attached to the rear end of the elongated hole 15, that is, the wire attachment ring. The tip 14a of the hook rod 14 is supported by the front edge of the elongated hole 15a, but since the tip 14a is bent at a right angle, it is securely fitted without falling off. The state is maintained.

In addition, the hook rod 14 has a long hole 15° 15a provided at a shifted position.
Since the tip 14a is inserted into the long hole 15a and the tip 14a is engaged with the elongated hole 15a, it is difficult to fall off in the natural state, and after the work is completed, it can be easily removed by pulling it out diagonally.

Then, a tension insulator 7 is connected to the tip of the U fitting 2 in the same way as in the case of the conventional one shown in FIG.
The hook ring part 18 of the hook ring 17 that has been connected is hooked onto the wire locking part 16 of the hook rod 14, and then the wire 13 is removed and wound around the wire attachment ring 4 as shown in FIG. It is installed twice.

When the electric wire 13 is to be held in place using the electric wire holding fitting 1 of the present invention constructed as described above, the wire locking portion of the hook rod 14 is fitted with the hook ring 17 to which the electric wire 13 is tied to the holding fitting 1. Since the hook is temporarily fixed to 16, the high voltage tension insulator 7 and the retaining fitting 1 are at the same height as the installation position of the electric wire 13.
There is no need to lift the high-voltage insulator 7 and the retaining fitting 1 as in the conventional case because they do not hang down.Furthermore, the electric wire 13 is located right next to the electric wire attachment ring 4, so you can hook it up without moving your body. The wire 13 can be removed from the ring 17 and subsequently attached to the wire attachment ring 4.

After the electric wire 13 is attached to the electric wire attachment ring 4, the hook ring 17 as well as the hook rod 14 are no longer needed, so they can be removed from the retaining fitting 1 and used for the next electric wire attachment operation.

As mentioned above, the present invention makes it extremely easy to install electric wires by providing elongated holes in both the left and right sides of the U fitting of the electric wire holding fitting, and temporarily fixing the electric wires to the hook rods that are removably fitted into the elongated holes. It can be done quickly and has many advantages, such as greatly streamlining the branching and connecting of overhead power lines at high places, which had previously been difficult and dangerous, and being economical as hook rods can be used repeatedly. There is.
