Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for polishing a portion of an end of a high voltage electric wire to be inserted into a terminal.

[0002]

2. Description of the Related Art In recent years, high-voltage electric wires have come to be coated with a coating material to prevent corrosion, so that it is necessary to remove the coating material from the portion to be inserted into a terminal. .

Further, even in the existing high-voltage electric wire, corrosion of the terminal portion progresses due to atmospheric pollution and the like, and it is necessary to replace the terminal portion, so that it is necessary to clean the surface of the connecting portion to remove foreign substances. did. For this purpose, conventionally, each high-voltage electric wire is in a state of being sanded by hand and polished.

[0004]

Conventionally, as described above, since it is a manual work, the efficiency is not improved, and there is a danger in a high place.

[0005]

In order to achieve the above-mentioned object, a rotating brush means which makes relative contact with the high-voltage electric wire from both sides and cleans the surface of the high-voltage electric wire by polishing, and a high-voltage electric wire is provided between the rotating brushes. This is an apparatus for polishing the outer periphery of an end of a high-voltage wire, which comprises a supporting means for guiding and supporting and a power source means for a drive motor of a rotary brush.

[0006]

When the switch is turned on, the rotating brush can efficiently remove the coating coating or the corrosion coating on the peripheral surface of the electric wire. By reversing the rotation of the opposing rotary brushes, the moving torque is canceled and the supporting force is reduced.
