1 to 3, the connection insulator of the extra-high voltage distribution processing wire according to an embodiment of the present invention is fixed by a connection part 97 to a support provided in an electric pole 10 or a pylon, and a sliding hole part ( 16) is provided with a variable cradle 14, a moving block 17 that is movably inserted along the sliding hole 16, and the moving block 17 is supported and connected to the insulator 18, and a sliding hole part ( 16) by fixing the moving block 17 to be moved along the moving fixing part 30 for determining the position of the insulator 18, and a fixing cradle 70 for fixing the cable to the insulator 18.

Therefore, after connecting the cable to the insulator 18 by manipulating the fixing cradle 70, the moving block 17 is inserted into the sliding hole 16 and moved while determining the position of the insulator 18, and the insulator 18 When the position of the insulator 18 is coupled to the variable cradle 14 by manipulating the movable fixing unit 30 .

The variable holder 14 of this embodiment may be applied when installing a plurality of insulators 18 on the variable holder 14 provided on the electric pole 10, as shown in FIG. ) can be applied even when installing a plurality of insulators (18).

The movable fixing part 30 of this embodiment is a gear tooth 32 formed on the inner wall of the sliding hole 16 , and a pinion member connected to the gear tooth 32 and rotatably installed on the moving block 17 . (34) and the pinion member (34) is installed to protrude from the moving block (17) so as to be connected to or separated from the gear, and when the gear is connected to the pinion member (34), the rotational movement of the pinion member (34) is constrained to constrain the pinion member When the constraint rack 36 constrains the 34 not to move along the sliding hole 16, and the constraint rack 36 protrudes to the outside of the moving block 17, the constraint rack 36 is moved toward the pinion member 34. When the restraint rack 36 and the pinion member 34 are gear-connected by moving the restraint rack 36 and the restraint rack 36 is inserted into the moving block 17 by the operator's operation, the restraint rack 36 is removed from the pinion member 34. It includes a coupling driving part 50 for releasing the restraint of the pinion member 34 while moving the restraining rack 36 in a direction away from it.

Therefore, when the operator inserts the moving block 17 into the sliding hole 16 in a state in which the release lever 58 is pulled downward when inserting the moving block 17 into the sliding hole 16, the restraint rack 36 moves. Since the block 17 maintains the inserted state inside, the restraint rack 36 and the pinion member 34 are separated, and the pinion member 34 is rotated in a gear-connected state to the gear tooth 32 while the moving block 17 is rotated. to maintain a movable state along the sliding hole 16 .

When the position of the moving block 17, that is, the position of the insulator 18 is determined, the operator releases the release lever 58 that was pulled in the downward direction so that the restraint rack 36 protrudes upward from the moving block 17, and the restraint rack ( 36) and the pinion member 34 are gear-connected.

As described above, when the locking rack 36 and the pinion member 34 are gear-connected, the rotational movement of the pinion member 34 is restricted, so that the pinion member 34 does not rotate inside the sliding hole 16, so the moving block ( 17) is constrained not to move along the sliding hole (16).

As described above, after combining and fixing the position of one moving block 17, another moving block 17 is inserted into the sliding hole 16 to adjust the distance between the moving blocks 17 while adjusting the distance between the moving blocks 17. 17) can be installed on the variable cradle 14 while adjusting the spacing.

In addition, the coupling driving unit 50 of this embodiment extends downward from the bottom surface of the movable block 17 and is provided on the inner wall of the column connected to the upper end of the insulator 18. A support panel 52 and a support panel ( The movable panel 54, which is moved while sliding along the column member in the vertical direction from 52), is installed on the upper surface of the movable panel 54, and can protrude toward the pinion member 34 through the opening on the upper surface of the movable block 17 is installed, and the pair of upper ends are arranged to maintain a gap, and interposed between the variable width member 56 in which the restraining rack 36 is installed at each upper end, and the support panel 52 and the movable panel 54 and a release lever 58 extending outward from the movable panel 54 to the outside of the column member to move the movable panel 54 in the vertical direction while being held by the operator and moving in the vertical direction.

Therefore, when the operator pulls the release lever 58 in the downward direction, the release lever 58 slides along the long hole formed long in the vertical direction to the column member, and the flow panel 54 formed integrally with the release lever 58 is While moving in the lower direction, the variable width member 56 is pulled in the lower direction.

At this time, since the width adjusting member pulled in the downward direction becomes narrow while sliding along the inclined surface formed on the inner wall of the column member, a pair of restraining racks 36 move toward the center of the column member while the pinion member 34 is moved. and the gear connection between the restraining rack 36 and the pinion member 34 is released.

In the state as described above, the operator determines the position of the insulator 18 while moving the insulator 18 in the longitudinal direction of the variable cradle 14, determines the position of the insulator 18, and releases the release lever 58 As the compressed elastic member 57 expands, the flow panel 54 rises upward, and as the flow panel 54 rises, the width control member rises.

At this time, since the inclined surface formed in the center of the opening of the moving block 17 opens the pair of upper ends toward the pinion member 34 while inserting the gap between the upper ends of the width adjusting member, the restraint rack installed at the upper end of the pair ( As the 36) moves toward the pinion member 34, the locking rack 36 and the pinion member 34 are gear-connected to restrict the rotational movement of the pinion member 34.

As described above, when the rotational movement of the pinion member 34 is constrained, the pinion member 34 is constrained not to move inside the sliding hole 16, so that the positions of the moving block 17 and the insulator 18 can be fixed. do.
