Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, an insulating tape has been wound around a live wire terminal to insulate it. However, this is troublesome and the adhesive strength is deteriorated due to aging during use. The wrapped tape may be easily peeled off and the effect of insulation may be diminished. Therefore, in order to improve this, an electric wire end cap made of a bottomed cylindrical body is attached.

[0003]

In such a conventional wire end cap, the inner wall of the bottomed cylindrical body is formed in a tapered shape so that the wire end is 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 hard. 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, the electric wire end treatment cap of the present invention has a taper portion on the opening side of a cover body made of a bottomed cylindrical body which is open at one end in the longitudinal direction. Engaging portions whose inner diameter is larger than the inner diameter of the cover body are continuously provided, and a serrated protrusion is provided around the inner peripheral wall of the engaging portion, while a through hole for inserting an electric wire is provided inside. A plurality of ridges for engaging with the ridges are engraved on the outer peripheral wall of a cylindrical cap body, a pressing portion is provided at the base end of the cap body, and a leg having elasticity at the tip of the cap body. By projecting a plurality of pieces and projecting a claw portion inside the tip of each of these leg pieces, and pushing the cap body into the engaging portion of the cover body with the electric wire inserted into the cap body and the cover body. While engaging a plurality of protrusions of the cap body with the protrusions of the engaging portion, The legs along the tapered portion is bent inward is obtained by constituting the wire so as to 咬止 with pawls.

[0005]

When the pressing portion of the cap body is pressed against the cover body with the electric wire inserted through the cap body and the cover body, the ridge of the cap body is formed as a serrated protrusion provided on the inner wall of the engaging portion of the cover body. At the same time, each leg at the tip of the cap body advances along the tapered portion, gradually narrowing the outer diameter of the tip, and the claw protruding inside the tip of each leg bites into the electric wire and bites. Stop and 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. Reference numeral 1 denotes a cover main body made of a bottomed cylindrical body, and an engaging 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 so that an inner peripheral wall of the engaging portion 4 is provided. One sawtooth-shaped ridge 5 is provided around the ridge. Then, the opening 2 of the engaging portion 4
Cuts 6 and 6 are provided on the sides.

Reference numeral 7 denotes a cap body which is pushed into and engaged with the engaging portion 4. The cap body 7 is formed of a cylindrical body having a through hole 8 through which an electric wire W is inserted. The cap body 7 has a plurality of ridges 9 projecting from the ridges 5 provided on the inner peripheral wall of the engaging portion 4 of the projection 7.
A disk-shaped pressing portion 10 is integrally provided at the base end of the base member, and a plurality of resilient leg pieces 11 are protruded concentrically from the tip of the cap body 7 so as to be inside the distal end of each of these leg pieces 11. The claw portion 12 protruding horizontally is provided in a horizontal shape.

The through hole 8 of the cap body 7 thus formed
The cap body 7 is inserted into the cover body 1 in a state where the live wire terminal of the electric wire W is penetrated into the cover body 1 and the live wire terminal is inserted into the cover body 1.
When the fitting portion 4 is inserted into the engaging portion 4 and the pressing portion 10 is further pushed in,
The engaging portion 4 of the cover body 1 is slightly expanded by the cuts 6, 6, and the plurality of protrusions 9 of the cap body 7 enter the engaging portion 4 of the cap body 7 and The cap body 7 is fixed to the cover body 1 in a state in which the cap body 7 is engaged with the saw-toothed ridges 5 provided around the cover body 1.

At this time, each leg 11 at the distal end enters along the tapered portion 3 of the cover body 1 as the cap body 7 is pushed into the engaging portion 4, whereby each leg 11 gradually becomes the outer diameter at the distal end. Each claw portion 12 protruding from the inside of the tip of each leg piece 11
However, as shown in FIG. 5, the wire W bites into the peripheral surface of the electric wire W and bites each other to hold the live wire end of the electric wire W accommodated in the cover body 1 without being pulled out.

In order to hold the wire end treatment cap at the live wire end of the wire W or remove the held wire W, the engaging portion 4 of the cover body 1 and the pressing portion 10 of the cap body 7 are hot. It is possible to perform work in the far-fusion operation by sandwiching it with an insulating tool such as a stick and fixing one and pushing in or pulling out the other, so there is no accident such as electric shock and safe work is possible. .

[0011]

As described above, the electric wire end treatment cap according to the present invention prevents the electric wire inserted into the cap body and the cover body from being removed by a simple operation of pushing the cap body into the cover body. Can be held at. Further, the electric wire end treatment cap of the present invention presses the cap body into the cover body and inserts the electric wire between the claw portions of each leg of the cap body, so that electric wires with different wire diameters can be freely and surely. It is easy to use and can be held.
