[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging and fixing tool for terminating a bypass cable, and is particularly used for supporting and fixing a high-voltage bypass cable end (plug-in type end) to an existing outdoor end. Suspension fixing tool.

[0002]

2. Description of the Related Art In order to avoid power outages due to construction of transmission and distribution lines, or for emergency power transmission in the event of an emergency,
Power is supplied from outside the area using a bypass cable.

Conventionally, such a bypass cable is connected to an existing cable terminal as follows. That is, as shown in FIG. 6 and FIG. 7, a suspension fixing tool 5 is installed on the arm 4 of the telephone pole 3 to which the outdoor terminal 2 such as the underground cable 1 is attached, and the high-voltage bypass cable 6 Attach plug-in end 7. Then, a lead wire 8 is connected to this plug-in type terminal 7,
The connector 9 attached to the distal end is connected to the terminal compression section 10 at the existing terminal by tightening the operation rod 11. Further, the outside of the connection portion of the connector 9 is covered with an insulating cover 12 for terminating the cable, and a spacer 13 is attached to the base end of the lead wire 8 to fix the distance between the phases. ing.

[0004] The hanging and fixing tool 5 for attaching the end of the bypass cable 6 has the following structure. That is, in the hanging fixing tool 5, as shown in FIGS.
A reinforcing rib portion 16 is fixed to an intermediate portion of an L-shaped support body 15 having a bypass cable fitting support portion 14 formed at one end, and a U-shaped cross-section is fixed to the other end of the support body 15. The metal fitting 17 is fixed. A wedge insertion hole 19 is formed at a predetermined position in each of the holding portions 18 vertically opposed to the mounting fixture 17. The holding portion 18 is attached and fixed so as to sandwich the arm 4 from above and below. After the metal fitting 18 is attached, the suspension fixing tool 5 is fixed by driving a wedge 20 so as to connect the upper and lower wedge insertion holes 19. In addition, in such a hanging fixing tool 5, the outer peripheral surfaces of the support main body 15 and the reinforcing rib portion 16 are provided with a protective coating such as a vinyl chloride resin.

[0005]

[Problem to be solved by the invention] The arm 4 has a width of 45 mm and 75
There are two sizes of the wedge insertion tool, but in the above-mentioned conventional hanging and fixing tool 5, only one wedge insertion hole 1 is provided at a position 45 mm from the fixing end of the holding portion 18 to the support body 15.
9 was drilled, so it could only be attached to the 45 mm wide arm 4. Further, the wedge 20 is attached to the support body 1.
5 is connected only by a plastic string body 21 such as a Saran string, so that there is a problem that the wedge 20 swings wobble during transportation or the like, which hinders the work.

The present invention has been made to solve these problems, and can be attached to a plurality of types of arms having different widths, and the workability is good without wedges obstructing during transportation. An object of the present invention is to provide a hanging fixing tool for terminating a bypass cable.

[0007]

According to the present invention, there is provided a hanging and fixing tool for terminating a bypass cable, which is attached to an arm to which a cable end is attached, and which supports and fixes a terminating end of a bypass cable connected to the terminating end. In, while providing a plurality of wedge insertion holes for driving and fixing a wedge according to the width of the mounting portion to the arm,
A projection for locking and fixing the wedge in the insertion hole when not attached to the arm is formed on the head of the wedge.

[0008]

In the hanging and fixing tool of the present invention, a plurality of wedge insertion holes for inserting and driving and fixing a wedge are provided in a mounting portion to the arm bar in accordance with the width of the arm bar. Therefore, after attaching this mounting portion to the arm, a wedge is inserted into an appropriate insertion hole and driven in, so that the hanging fixing tool is firmly attached and fixed to each of a plurality of types of arms having different dimensions. be able to. In addition, since a locking projection is formed on the head of the wedge, when the wedge is inserted into an appropriate insertion hole when the wedge is not attached to the arm, such as during transportation, the projection is engaged by the projection. It is fixed and prevented from falling off and swinging. Therefore, the work is easy without the wedge being in the way.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are a front view and a top view, respectively, showing one embodiment of a hanging and fixing tool for terminating a bypass cable according to the present invention. In these figures, the same parts as those in FIGS. 8 and 9 are denoted by the same reference numerals, and description thereof will be omitted.

In the hanging and fixing tool of the embodiment, two wedge insertion holes 19 are respectively formed at predetermined positions of the mounting and fixing bracket 17 for mounting on the arm. That is, in the holding portion 18 which is disposed oppositely above and below the mounting fixture 17,
From the fixed end to the support body 15 according to the width of the arm
Wedge insertion holes 19 are formed at positions of 45 mm and 75 mm, respectively. In addition, the head of the wedge 20 connected to the upper end of the support main body 15 by the plastic string body 21 has:
A spherical projection 22 is formed, and when the wedge 20 is not used, when the wedge 20 is deeply inserted into the wedge insertion hole 19, the projection 22 once passes through the insertion hole 19 and abuts on the lower surface of the upper holding portion 18. It is configured to be locked. Note that the spherical projection 22 is provided with the insertion hole 19 of the wedge 20 when not in use.
It is desirable to use a material having good elasticity, or to have a structure that can freely project and retreat so that it can be easily inserted into.

As shown in FIGS. 3 and 4, in order to attach and fix the hanging fixing tool of the embodiment constructed as described above to the arm bar 4 such as a telephone pole to which the existing terminal is attached, as shown in FIGS. The arm member 4 is sandwiched between the arm members 4, and the mounting fixture 17 is attached to the arm member 4 so that the fixed end portion is tightly contacted with the side peripheral surface, and a wedge insertion hole 19 at a position suitable for the width of the arm member 4. Then, the wedge 20 is driven so as to connect the upper and lower sides. In this manner, the wedge 20 is driven down to the lower side of the protrusion 22 formed on the head, and is sufficiently fixed.
Further, when carrying the hanging fixing tool, as shown in FIG. The lower surface of the upper holding portion 18 is abutted and locked to the projection 22. Thus, even when the hanging fixing tool is not mounted, the wedge 20 is inserted into the insertion hole 19 of the mounting fixture 17.
Since it is firmly fitted and fixed inside and there is no falling off or rattling, it is easy to carry.

[0013]

As described above, the hanging and fixing tool for terminating a bypass cable according to the present invention can be easily attached to a plurality of types of arms having different widths. Further, since the wedge can be temporarily fixed at the time of transportation or the like, the wedge does not interfere and the workability is good.
