DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire terminal treatment cap which is fitted to a live wire terminal for insulation purpose when a low piezoelectric wire is installed between utility poles.

[0002]

2. Description of the Related Art Conventionally, an insulating tape has been wound around a hot wire terminal for insulation treatment. However, this operation is troublesome, and the adhesive force is reduced due to aging during use. The wound tape may be easily peeled off, and the effectiveness of insulation may be reduced. Therefore, in order to improve this, a cable end cap made of a bottomed cylindrical body is mounted.

[0003]

In such a conventional wire end treatment cap, the inner wall of the bottomed cylindrical body is formed in a tapered shape so that the wire end can be easily inserted, and the wire is formed along the taper. Since it is a thing which pushes in strongly and is pinched, there is a possibility that it will come out unless it pushes in too tightly. In addition, there is a restriction that it cannot be used for electric wires having different wire diameters. In view of such a conventional technology, an object of the present invention is to provide an electric wire end treatment cap that can easily and reliably hold an electric wire and can be used for electric wires having different diameters. And

[0004]

In order to achieve the above object, an electric wire end treatment cap according to the present invention is provided with a tapered portion on the opening side of a cover body composed of a bottomed cylindrical body opened at one end in the longitudinal direction. A cylindrical cap having a threaded portion whose inner diameter is larger than the inner diameter of the cover main body is continuously provided, and a female screw is engraved on an inner peripheral wall of the threaded portion, while a through hole for inserting an electric wire therein is provided. A male screw is screwed into the female screw on the outer peripheral wall of the body, a knob is provided at the base end of the cap body, and a plurality of elastic pieces are protruded from the tip of the cap body to project these. A claw portion is protruded inside the tip of each leg piece, and the cap body is screwed into the cover body in a state where an electric wire is inserted through the cap body and the cover body, thereby tightening each leg piece along the tapered portion. To bend inward so that the claws catch the wire at each claw Are those that form.

[0005]

[Operation] When the cap body is screwed into the cover body with the electric wire inserted through the cap body, and further turning the knob, the cap body is tightened, and the male screw of the cap body and the female screw of the screwing part are screwed together. As the advancing progresses, each leg at the tip of the cap body advances along the tapered portion and gradually narrows the outer diameter of the tip, and the claw protruding inside the tip of each leg bites into the electric wire and bites, Hold the wires so that they do not come off.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5, reference numeral 1 denotes a cover main body formed of a bottomed cylindrical body, and a screwing portion 4 having an enlarged inner diameter is continuously provided near an opening 2 of the cover main body 1 via a tapered portion 3. A female screw 5 is engraved on the inner peripheral wall of the part 4.

Reference numeral 6 denotes a cap which is screwed to the screw portion 4. The cap 6 is formed of a cylindrical body having a through hole 7 through which the electric wire W is inserted.
A disk-shaped knob 9 is integrally provided at the base end of the cap body 6, and a leg piece 10 having elasticity is concentrically provided at the tip end of the cap body 6. A plurality of claw portions 11 projecting inward from the distal ends of the leg pieces 10 are provided in a horizontal shape.

[0008] The through hole 7 of the cap body 6 formed in this manner.
4, the male screw 8 of the cap body 6 is screwed into the female screw 5 of the cover body 1 in a state where the live wire terminal of the electric wire W is penetrated and the hot wire terminal is inserted into the cover body 1. When the knob 9 is further rotated in the direction of the arrow shown in FIG. 4, the male screw 8 of the cap body 6 is screwed with the female screw 5 and the cap body 6 enters the cover main body 1. Then, when each leg 10 at the tip of the cap body 6 enters along the tapered portion 3 of the cover body 1, each leg 10 gradually narrows the outer diameter of the tip,
Each of the claws 11 protruding from the inside of the tip bites into the peripheral surface of the electric wire W and bites each other, so that the electric wire W accommodated in the cover body 1 is formed.
Of the live line terminal is securely held without being pulled out.

When it is necessary to remove the hot wire end of the electric wire W securely held in the cover main body 1 in this manner, the knob 9 of the cap body 6 is rotated in the opposite direction to the tightening. Then, with the reverse rotation, each leg piece 10 expands along the tapered portion 3 and retreats, the bite of the electric wire W by each claw portion 11 is released, and the electric wire W can be easily removed.

The operation of holding the hot wire end of the wire W in the wire end processing cap or removing the held wire W is performed by the screwing portion 4 of the cover body 1 and the knob 9 of the cap body 6. By holding each of them with an insulating tool such as a hot stick and rotating one of them, it is possible to carry out a work by a long melting operation, so that the work can be performed safely without an accident such as electric shock.

[0011]

As described above, the electric wire end treatment cap according to the present invention provides the electric wire inserted into the cap body and the cover body to the tip of the cap body by screwing the cap body to the cover body. Since the claw portions of the provided leg pieces securely hold the electric wire, the electric wire can be held so as not to come off from the cover body. Also, electric wires having different wire diameters can be reliably held by adjusting the tightening of the cap body. The wire held in this manner can be easily removed as needed by screwing the cap body off the cover body, and the wire end treatment cap is not damaged at all. They can be reused accordingly.
