According to this, branching to the transformer T can be easily and conveniently. There is a technical feature of being able to easily and conveniently install the wire clamp 25 to the suspension insulator 23 because it can be connected and the movement of the eye buckle 22 and the suspension insulator 23 can be fixed as needed.

The arm iron 10 is a rectangular metal tube, and in this embodiment, is installed side by side with a telephone pole P equipped with a transformer T therebetween. A first coupling hole 11 penetrating up and down is integrally formed on the upper surface of one end of the arm iron 20 installed side by side in this way, and a second coupling hole 12 and a second coupling hole 12 are formed on both sides based on the first coupling hole 11. Fixing mechanisms 30 are respectively formed.

Here, the first cotter pin 21a is inserted through the first coupling hole 11 and fixed through the first split pin 21b, and the second coupling hole 12 has one end of the suspension insulator 23 . Removably fixed.

The eye buckle 22 is rotatably installed on the armrest 10 via the first cotter pin 21a.

The eye buckle 22 is a metal member having a '⊂' shape when viewed from the front, and a hole communicating with the first coupling hole 11 of the armrest 10 is integrally formed at the distal end thereof. The eye buckle 22 is formed by the first cotter pin 21a penetrating the hole and the first coupling hole 11 in a state in which the hole is arranged to communicate with the first coupling hole 11 of the armrest 10. It is fixed, and the first cotter pin 21a is fixed to the armrest 10 via a first split pin 21b that is detachably fitted to the penetrating end portion. And an oval-shaped truncated hole 22a is integrally formed at the vertex of the eye buckle 22, and the truncated hole 22a is, as shown in FIG. ), the cross-sectional area gradually decreases toward the end, and when the truncated portion 23e of the suspension insulator 23 is fitted into the truncated hole 22a, the first connection portion 23b of the suspension insulator 23 is movement towards it is limited.

The suspension insulator 23 is composed of an insulator part 23a, a first connection part 23b, a second connection part 23c, a hinge part 23d, a truncated part 23e and a stopper 23f, In this case, it is rotatably inserted into the eye buckle 22 to insulate it so that it does not make electrical contact between the overhead distribution line L and the arm iron 10 , and is selectively installed on the arm iron 10 to limit the rotation of the eye buckle 22 . do

The insulator part 23a is a member made of an insulating material, and a first connection part 23b and a second connection part 23c made of a metal material are formed at both ends, respectively, and a first connection part 23b and a second connection part 23c are formed. is maintained in an electrically insulated state by the insulator (23a). A hole through which the second cotter pin 24a is inserted is integrally formed in the second connection part 23c. On the other hand, a bolt 23b-1 having a thread on the outer circumferential surface is integrally formed at the distal end of the first connection part 23b, and a hinge part 23d is detachably fastened to this bolt 23b-1, where the hinge The branch 23d is a stopper that prevents the first connection portion 23b from being separated from the eye buckle 22 and the second coupling hole 12 and serves as a central axis so that the first connection portion 23b can be rotated. And the first connection part 23b passes through the truncated hole 22a of the eye clasp 22 and is inserted into the second coupling hole 12 of the armrest 10, and the hinge part is fastened to the bolt 23b-1. It is fixed to the arm iron 10 via (23d). When the first connecting portion 23b is installed on the armrest 10 as described above, the rotation of the eye buckle 22 around the first cotter pin 21a by the first connecting portion 23b is naturally restricted.

On the other hand, on the outer peripheral surface of the first connection portion (23b) is integrally formed with a truncated portion (23e) that is detachably fitted and engaged in the truncated hole (22a). Here, the truncated portion 23e is fitted into the truncated hole 22a to limit excessive movement of the first connection portion 23b and rotation of the first connection portion 23b based on the shaft center. The truncated portion 23e is manufactured in a trapezoidal shape (refer to FIGS. 3 and 4) in which the cross-sectional area gradually decreases from one end (insulator direction) to the other end (bolt direction), like the truncated hole 22a. And on one side (between the insulator portion and the truncated portion) of the truncated portion 23e, a stopper 23f protruding in a direction perpendicular to the first connecting portion 23b is integrally formed.

The wire clamp 25 is composed of a fixed sleeve 25a and a sleeve cover 25b. In this embodiment, the second connection part 23c of the suspension insulator 23, the second cotter pin 24a, and the second split pin It is interconnected via (24b), and serves to electrically interconnect the overhead distribution line (L), the jumper line (J), and the branch line (BL). The fixed sleeve 25a has an 'S' shape as a whole, and the ends of the overhead power distribution line (L) and the jumper line (J) are brought in to face each other, and the branch line (BL) is placed under them. When it is pressed with a tool, the overhead distribution line (L), the jumper line (J) and the branch line (BL) drawn in while the outer surface is closed are electrically interconnected. In addition, if necessary, the overhead distribution line (L), the jumper line (J), and the branch line (BL) may be fixed in various known methods.

The sleeve cover 25b is a member of an insulating material, and in this embodiment, surrounds the fixed sleeve 25a to protect it from insulation and external forces.

For example, the branch line BL drawn from the fixed sleeve 25a is electrically connected to the transformer T. As such, it is possible to easily connect the overhead distribution line (L), the jumper line (J), and the branch line (BL) by using the wire clamp (25) as well as the branch line (BL) drawn out from the wire clamp (25) to the transformer (T). ) has the advantage of greatly improving the convenience of work in that it can be easily connected to.

As mentioned above, the suspension insulator 23 is rotatably coupled to the eye buckle 22, so that when the wire clamp 25 is to be installed on the suspension insulator 23, its installation is not easy due to movement.

Accordingly, when the hinge portion 23d is separated from the first connection portion 23b of the suspension insulator 23 and then the first connection portion 23b is moved toward the armrest 10, formed on the outer peripheral surface of the first connection portion 23b While the truncated portion 23e is fitted into the truncated hole 22a of the eye clasp 22, the movement of the first connecting portion 23b is limited. And when the separated hinge part 23d is fastened to the bolt 23b-1 inserted through the second coupling hole 12 of the armrest 10, the eye buckle 22 is firmly attached to the armrest 10. is fixed Accordingly, the eye shackle 22 is not only limited in rotation by the suspension insulator 23, but also the first connection portion as the truncated portion 23e of the suspension insulator 23 is inserted into the truncated hole 22a of the eye clasp 22. The deflection and rotation of (23b) are naturally limited. As described above, as the movement of the eye clasp 22 and the suspension insulator 23 is limited and it is firmly fixed to the arm iron 10, it is possible to easily and conveniently install the wire clamp 25 to the suspension insulator 23. It has the advantage of maximizing the convenience of work.

The fixing mechanism 30 is composed of a bracket 31 and a support rib 32, and in this embodiment, it is installed so as to be rotatable (folded) through a hinge (not shown) at one end of the armrest 10. 1 The cotter pin 21a is used to fix the eye latch 22 so that it does not rotate, and in addition to this, it is used for temporarily hanging various tools.

The bracket 31 is a member having an approximately 'C' shape when viewed in a plan view. In this embodiment, the bracket 31 is rotatably (folded) installed at one end of the arm convex 10 via a hinge (not shown). . The bracket 31 installed in this way is rotated around a hinge (not shown) and placed on the upper surface of the armrest 10, and the movement of the eye buckle 22 is restricted by the bracket 31 placed in this way.

The support rib 32 is integrally formed with the bracket 31 and serves to support the bracket 31 with one side facing the side of the armrest 10 . As such, since the support rib 32 stably supports the bracket 31 , it is possible to prevent sagging even when a relatively heavy object is placed or hung on the bracket 31 . In particular, it is very useful in terms of being able to fully utilize the space around the armrest 10 because it is possible to mount relatively heavy parts such as the wire clamp 25 sufficiently.

6A to 6C are diagrams for explaining an embodiment of the use of an overhead distribution device for convenient branching of an overhead distribution line to a transformer according to the present invention, which will be described with reference to the following.

As shown in Figure 6a, the arm iron 10 is installed side by side at the upper end of the electric pole P where the transformer T is installed, and the overhead wire fixing unit 20 is installed in each arm iron 10.

When explaining the installation process of the overhead wire fixing unit 20 in more detail, the eye latch 22 is placed on the arm iron 10 and then the first cotter pin 21a is passed through the first coupling hole 11 . It is inserted so that the eye clasps 22 and the arms 10 are interconnected via the first cotter pin 21a.

Then, the first split pin 21b is coupled to the end of the penetrating first cotter pin 21a to fix the first cotter pin 21a from being separated from the arm iron 10 .

When the eye buckle 22 is fixed as described above, the suspension insulator 23 is connected to the eye buckle 22 via the first connection part 23b and the hinge part 23d, and the second connection part of the suspension insulator 23 After coupling one end of the wire clamp 25 to 23c, the second cotter pin 24a and the second split pin 24b are connected to each other.

When the eye clasp 22, the suspension insulator 23, and the wire clamp 25 are interconnected as described above, the overhead distribution wire (L) and the jumper wire (J) are respectively connected to the fixed sleeve 25a of the wire clamp 25. After placement, use a tool to firmly bite the overhead distribution line (L) and jumper wire (J), and if necessary, you may install a branch line (BL) on the fixing sleeve (25a).

When the overhead distribution line (L), the jumper line (J), and the branch line (BL) are interconnected via the fixed sleeve (25a) as described above, the sleeve cover (25b) is covered so that they are not exposed to the outside.

On the other hand, if the overhead distribution line (L) is installed in a place where a lot of wind blows, the suspension insulator (23) and the eye buckle (22) having an integrated structure with the overhead distribution line (L) by the wind can be severely shaken by this, As a result, the jumper line J or the branch line BL also vibrates.

If the jumper wire (J) or branch wire (BL) is shaken in this way, the operator cannot but feel difficulties in work, and in such a place where the wind blows strongly, the eye buckle 22 and the suspension insulator 23 are caused by external force (wind). It needs to be fixed so as not to be shaken by the

As shown in FIGS. 6B and 6C , first, the eye buckle 22 is installed on the armrest 10 via the first cotter pin 21a and the first split pin 21b.

Then, the fixing mechanism 30 is rotated about the hinge (not shown) so that the eye buckle 22 is not rotated around the first cotter pin 21a and put on the upper surface of the armrest 10, the bracket 31 ), the upper side of the eye buckle 22 is naturally detained by the rotation is limited.

In the state in which the rotation is restricted in this way, the first connection part 23b of the suspension insulator 23 is inserted so that it passes through the truncated hole 22a and the second coupling hole 12 of the eye buckle 22, and then the first connection part 23b The hinge part 23d is fastened to the bolt 23b-1, and for reference, the truncated part 23e is naturally inserted into the truncated hole 23e while the first connection part 23b is moved toward the armrest 10. .

As the hinge part 23d is fastened to the bolt 23b-1 as described above, the suspension insulator 23 is fixed to the arm iron 10 as well as the fix mechanism 30 and the rotation of the eye buckle 22 is restricted. , as the truncated portion 23e is inserted into the truncated hole 23e, it is possible to restrict both excessive movement and rotation of the suspension insulator 23 and movement along the longitudinal direction of the truncated hole 22a.

And when the eye buckle 22 and the suspension insulator 23 are firmly fixed to the armrest 10, the suspension insulator 23 and the wire clamp 25 are connected to the second cotter pin 24a and the second split pin 24b. After interconnection through the medium, the overhead distribution line (L) and the jumper line (J) and the branch line (BL) are electrically connected using the fixing sleeve 25a of the wire clamp 25.

As such, even if an external force (wind) acts on the overhead distribution line (L), jumper wire (J), and branch line (BL), the eye buckle 22 and the suspension insulator 23 are firmly fixed to the arm iron 10 so as not to move. Therefore, it is possible to suppress the shaking of the overhead distribution line (L), jumper wire (J), and branch line (BL) as much as possible, and accordingly, the operator can proceed with the inspection work in a safe state, which has a positive effect of improving the working environment. You can look forward to it.

Although the present invention has been described in detail only with respect to the specific embodiments described, it is natural for those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention, and it is natural that such variations and modifications belong to the appended claims.
