Description

[Detailed explanation of the invention] When holding a wire to a telephone pole, a holding fitting is attached to the pole, a clamp fitting is attached to the wire, and the clamp fitting attached to the electric wire is secured to the holding fitting with a wire. . As shown in Fig. 2, the conductor B of the electric wire A is exposed and the exposed part is clamped with a clamp fitting C, and a stop wire is connected to the branch part D of the clamp fitting C, so these parts are not exposed to the outside. An insulating cover is provided for insulation. This insulating cover is made of vinyl chloride or polyethylene, and is split in half along the wire so that it can be placed over the clamp fittings and wires that are held in place, or in half so that it can be opened from one side. A hook provided along the opening 5 allows the opening 5 to be closed. However, if the wire rotates around the stop wire due to twisting of the wire, it will be difficult to close the split 5 of the insulation cover, and if it is already closed, the split will act to open the insulation cover. was sometimes incomplete.

This invention aims to provide an insulating cover that does not have such problems, and the insulating cover is formed so that the wire and clamp can freely rotate around the stop wire in response to twisting of the wire. It is.

To explain one embodiment of the present invention shown in the figure, this insulating cover includes a cylindrical clamp fitting covering part 1 and a cylindrical puller provided so as to protrude like a branch from the middle of the clamp fitting fitting covering part 1. It consists of a stop wire covering part 2. A wire insertion port 3 is formed at one end of the clamp metal fitting covering portion 1, and the stop wire covering portion 2 is provided so as to be located on the opposite side of the wire insertion port 3. A split 5 is provided along the entire length of the clamp fitting covering portion 1 on the side of the locking wire covering portion 2 along a plane dividing both the clamp fitting fitting covering portion 1 and the locking wire covering portion 2 into two. Fins 8 are provided facing each other along both sides. The fin 8 has a hook 9 and a hole 10 for it.
When the hook 9 is firmly inserted into the hole 10, the opposing fins come into close contact and the split 5 is closed, and when the hook 9 is removed from the hole 10, the split 5 can be opened. There is.

The small parts are overlapped with each other by half the thickness of the wall in cross section at a position opposite to the split 5 on the opposite side to the side with the split 5 of the clamp metal covering part 1. It has a fin and a semi-cylindrical thin connecting part 11 that projects outward, and can be opened from the fin 8 side using the connecting part 11 as a hinge. Note that a portion of the end portion forming the wire insertion opening 3 is formed so that the portion on the side of the split 5 and the side opposite thereto simply overlap each other by the small fins.

Retaining wire covering portion 2 of clamp metal fitting covering portion 1
The protruding surface 6 is formed into a flat surface, and a circular hole 7 is provided so as to overlap the central split 5.

The locking wire covering part 2 is the clamp metal covering part 1
It is formed separately. Retaining wire covering part 2
has a shape in which two thin small cylinders 2b protrude in parallel from one end of a cylinder part 2a having a substantially rectangular cross section.
A continuous plate-like structure is formed between the small cylinders 2b. Cylinder part 2
The end part a without the small cylinder 2b has a circular cylindrical part 12, most of which becomes the groove bottom, and a flange part 13 that follows the end surface.
The cylindrical portion 12 fits inside the hole 7, and the flange 1
3 is in contact with the inner surface of the surface 6, so that the stop wire covering part 2 can freely rotate relative to the clamp metal fitting covering part 2. However, an annular groove is formed on the cylindrical surface of the hole 7, and the retaining wire covering portion 2
The flange portion 13 formed on the end surface of the holder may be fitted into the flange portion 13 to be rotatable.

The retaining wire covering portion 2 is divided into two by a split 14 that is a plane including the center line of the two small cylinders 2b, and a half is formed along the split 14 of the small cylinder 2b on one side. Connected by a cylindrical connecting part 15, 2
Fitting of the hook 9a provided on one side of the plate-shaped continuous portion between the small cylinders 2b and the hole 9b provided on the other side, and the hook 9a provided on the opposite side of the connecting portion 15 By fitting the hole 10a with the hole 10a, it is possible to maintain the unit together, and it is also possible to open from the side.

After connecting the clamp fitting C attached to the electric wire and the stop metal fitting attached to the utility pole with a wire, cover the stop wire sheathing part 2 that was opened in advance so that the wire fits inside the small tube 2b and close it. .

Next, the clamp fitting covering part 1 of the insulating cover is opened from the split 5 and positioned on the outer periphery of the clamp fitting C, and the inner surface of the hole 7 is located in the cylindrical part 12 of the stop wire covering part 2, and the surface 6 is The cover is placed so that the collar 13 is located on the inside, and the hook 9 is inserted into the hole 10 to close the split. As shown in the figure, the left end of the clamp fitting sheathing part 1 is closed when the end of the electric wire is housed in the clamp fitting sheathing part 1, and the electric wire is further extended beyond this stop part as shown in the figure. If the wire is to be extended to the left, the groove 4a provided at the left end of the clamp fitting covering portion 1 is cut off, the wire insertion hole 4 is opened, and the wire is extended to the outside from here.

According to the present invention, since the stop wire covering part 2 can freely rotate with respect to the clamp metal fitting covering part 1, even if the wire is twisted with respect to the stop wire, the clamp metal fitting can be rotated in the direction of inclination of the wire. The covering part 1 and the stop wire covering part 2 rotate with each other, making it easy to cover the wire, and even if the wire is twisted after being covered, the cover will not open the split due to prying. Can be kept closed.
