Description

[Detailed Description of the Invention] This invention relates to a protection device for protecting the wire outlet of an insulating cover that covers the wire retaining portion during overhead wiring work to a utility pole.

Conventionally, in this type of insulating cover, the wire outlet is wide open to accommodate the direction and position of the wire, and is only closed with a thin, flexible tongue, so when the wire is pulled out, There was a risk that small birds could nest or snakes could enter through the gaps created by the wires or between the tongues and come in contact with the bare wires, resulting in electric shocks and power outages.

In view of the above-mentioned drawbacks, an object of the present invention is to provide a protection device for an insulating cover that covers a wire holding part, which can securely close the wire outlet and safely protect the wire. .

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a spear metal fitting whose one end is connected to a utility pole (not shown) via arm arm branch line 2, tambuckle 3, etc. An insulator 6 is connected to the other end via an insulator metal fitting 4, a strap 5, and the like.

Reference numeral 7 denotes a locking metal fitting pivotally attached to the core rod 6a of the insulator 6, and can lock the electric wire D in cooperation with a locking metal fitting 8 externally fitted around the center thereof.

Reference numeral 9 denotes an insulating cover formed to cover the vicinity of the retaining fitting 7, and is molded from an insulating material such as rubber or plastic into a hollow body shape that can be divided into left and right halves, with a right side piece 9R and a left side piece. It surrounds the 9L retaining fitting 7 and is assembled in the shape of palms together.

Reference numeral 10 denotes an electric wire outlet, which is inserted into the upper end of the insulating cover 9 in order to draw the electric wire outlet opened on the right side of the insulating cover 9 upwardly, and which is locked by the catch fitting 7. protruding from the part,
Further, in this example, the opening is approximately rectangular, and locking protrusions 11, 11 each having a hook-shaped cross section are provided protruding along the longitudinal direction at the upper ends of both sides in the longitudinal direction.

Reference numeral 13 denotes a protection plate attached to the upper surface of the wire outlet 10 in a detachable and horizontally sliding manner.
It is formed into a rectangular shape that can be closed off, and on the back side of the long sides 13a, there are hook-shaped locking strips 14, 14 along the long sides 13a that connect the locking protrusions of the wire outlet 10. A through hole 15 is formed in the center of the strip 11 so that it can be engaged with the wire 11, and a through hole 15 is formed in the center of the hole 15 to allow the wire to be inserted. The position can be adjusted left and right.

Reference numeral 16 denotes a cap that protrudes upward from the periphery of the through hole 15 so as to surround the electric wire D inserted through the through hole 15, and in this example, a plurality of cap pieces are formed in a tapered shape as shown in the figure. 16a to 16a are arranged in parallel in a branched shape that can expand and contract the mouthpiece diameter, and each mouthpiece piece 1
6a is bent into a wave shape to ensure flexibility, and each cap piece 16a can be bent individually.

In this example, the through hole 15 of the protective plate 13 and the left edge of the protective plate 13 are separated by a cut 17, and when the protective plate 13 is expanded laterally at the cut 17, the through hole 15 and the left edge of the protective plate 13 are separated. The electric wire D can be inserted into the base 16.

Further, reference numeral 18 denotes a stopper provided on the back surface of the short side 13b of the protection plate 13 in order to restrict the sliding range of the protection plate 13.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the wire outlet 10 of the insulating cover 9 that covers the wire retaining section has this wire outlet 10.
0, and the base 16
A protection plate 13 is slidably attached to the upper edge of the wire outlet 10 and is flexible to the cap 16 so as to surround the wire outlet when the wire D is pulled out from the wire outlet 10. Since it is provided with a
As a result, the wire D can be positioned by adjusting the position of the wire D, and the base 16 can be encircled along the wire D in accordance with the drawing angle of the wire D. Refract or
It has the advantage that the wire extraction portion can be protected without damaging the wire extraction port 10.

Furthermore, when the drawn out electric wire D is surrounded by the base 16 and wrapped around it with adhesive tape, the wire extraction part is closed in a sealed manner, and the electric wire D is fixed to the insulating cover 9. This has the effect of preventing the intrusion of wires D, etc., and stably holding the drawn-out electric wire D.

In particular, the cap 16 is divided into a plurality of cap pieces 16a, and each cap piece 16a is individually endowed with flexibility, so that the cap 16 can be bent along the drawing angle of the electric wire D. Even in a bent state, the diameter of the mouthpiece can be expanded or contracted according to the diameter of the wire D, so that the wire D that has been pulled out is closely surrounded by the mouthpiece 16 and the wire outlet 10 is securely closed. It has the advantage of not only being able to block the wires, but also making it easy to dispose of the drawn out wires.

Note that the protection plate 13 is formed to be detachable from the wire outlet 10, so if the cap 16 is damaged, the insulation cover 9 can be replaced by replacing the protection plate 13.
It has the effect of significantly extending the period of use.

That is, in the present invention, the wire outlet of the insulating cover that covers the wire retaining portion is formed so as to be able to close the wire outlet, and a protection plate having a base for drawing out the wire is provided at the wire outlet. The electric wire drawer is slidably attached to the electric wire drawer along the edge thereof, and is provided with flexibility so as to be able to surround the electric wire when the electric wire is drawn out from the electric wire drawer opening. This is an extremely practical and excellent device as a protective device for an insulating cover, as it can securely close the opening, safely protect the electric wire, and prevent electric shock accidents.
