Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a wire end cap for live work.

"Prior art" It is necessary to cover the terminal part of the wire in the part to be pulled to the armor, but in the live-line work, the covering work cannot be performed directly by hand, and the covering work can be performed from a remote position. It was also difficult to do. That is, since the above-mentioned terminal portion forms the free end (free end) of the electric wire and is not held at a fixed position, it is swayed by an external force and moved to stand sideways or upward, or hang downward. Since such a free rocking terminal is mainly located on the arm part above the utility pole, the covering work from a remote position is dangerous as well as the covering work by hand, and there is a problem that it is difficult to construct easily. Therefore, an end cap for hot stick operation, which has a horizontal end cap at the tip of the handle (No. Shokai 62-70626), was used, but it is good when the end of the wire is horizontal, but it is facing upward or downward. If the handle is hot, the handle (hot stick) must be held horizontally, and it is difficult to attach the end cap to the wire end when the handle is upward or downward.

[Problems to be Solved by the Invention] The object of the present invention is to obtain an electric wire terminal cap for hot wire work that can be easily attached to the free terminal portion from a remote position.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention forms an upward protruding portion in a direction parallel to the center line of the insulating cylinder on the side surface of the bottomed hollow insulating cylinder, and one end of the protruding portion is One of the normally-closed holding claw and the hollow insulating cylinder that extends outward from the open end of the insulating cylinder along the center line and has a horizontal through hole that is orthogonal to the center line in the extension. The electric wire is inserted into the through hole and formed by the extension portion and the other normally-closed holding claw so as to hold the electric wire by the force of the spring, and the base ends of these holding pawls are extended to normally open by the force of the spring. It is composed of an electric wire terminal cap for hot-line work, which is composed of an insulating clip forming an operation piece.

"Action" Therefore, the long-opening handle 11 with the handle 10 causes the normally-open operation piece 9,
When 9'is clamped and the operating pieces 9, 9'are closed against the force of the spring 8, the normally-closed clamping claws 6, 6'open (the state is shown in FIG. 5), and the opened clamping claw 6 is opened. , 6 ', the open end 3 of the insulating cylinder 1 is opened. The opening direction is horizontal as shown in FIG. 5, but in the case of upward or downward, the normally closed operation pieces 9, 9 '.
By making the longitudinal direction (Fig. 7) and the direction of the yatco 11 orthogonal, it is possible to close against the spring 8. Therefore, if the handle 10 is gripped in that state and the insulating cylinder 1 is moved in the direction of arrow a in FIG. 5, the end portion 12 of the electric wire 12 'will pass between the holding claws 6 and 6'and the insulating cylinder 1 It is stored in 1 (Fig. 6). And when you open Yatco 11, the above operation piece 9,
The wire 9'is opened by the force of the spring 8 and the holding claws 6 and 6'are closed, the wire 12 'is held by the wire holding portion 7, and the insulating cylinder 1 is attached to the terminal portion 12 of the wire 12' (first (Fig. 7).

[Example] A protrusion 2 in a direction parallel to a center line c of the insulating cylinder 1 is formed on a side surface of a bottomed hollow insulating cylinder 1 made of rubber. The protrusion 2 is integrally formed with the insulating cylinder 1, and a long core 13 extending in the direction of the center line c is built in the protrusion 2 to prevent the rubber-made insulating cylinder 1 from sagging. ing. One end of the protrusion 2 thus formed extends outward from the opening end 3 of the insulating cylinder 1, and the core 13 also extends inside the extension 2 '. In the extension 2 ', a through hole 4 orthogonal to the center line c is formed.
To drill. An insulating clip 5 is arranged on the side of the through hole 4 in a direction orthogonal to the center line c, and one of the normally-closed holding claws 6 and 6'of the clip 5 is inserted into the through hole 4 and the insertion is performed. The lower portion 4'of the through hole 4 is fitted in the recess 14 formed on the inner surface of the holding claw 6, and the plug 15 is fitted in the space formed between the outer surface of the nail 6 and the upper portion 4 "of the through hole 4. Then, the stopper 15 and the extension portion 2'are fixed by bolts 16 to support the claw 6 and the extension portion 2 ', and the wire holding portion is held by the inner surface of the lower portion 4'and the inner surface of the other holding claw 6'. The base end portions of the sandwiching claws 6 and 6'as described above are extended to form normally open operation pieces 9 and 9'by the force of the spring 8. The operation pieces 9 and 9'are formed.
When 9 is closed by the yatco 11 against the spring 8 as shown in FIG. 6, the clamping claws 6 and 6'open, and the claws 6 opened are opened.
As described above, the open end 3 appears between 6 '. The holding claws 6, 6'and the operating pieces 9, 9'are made of synthetic resin.

[Advantage of the Invention] Since the present invention is configured as described above, the electric wire terminal portion 12 is formed so that it can swing freely at a high place such as a portion of the arm 18 of the utility pole 17 in the lateral direction and in the upward or downward direction. It is possible to attach the terminal cap safely, quickly and easily from a remote location by using the Yatco 11 or the like.
