Wire connection device and using method thereof

Abstract

The invention provides a wire connection device and a using method thereof. The device comprises a conductive connection mechanism. Two ends of the conductive connection mechanism are plugged with wire joints; the conductive connection mechanism comprises a shell and an inner insulating sleeve in threaded connection with an inner side of the shell; a conductive assembly electrically connected withthe wire joints is arranged in the inner insulating sleeve; strip-shaped sliding holes are arranged in an end part of the inner insulating sleeve at intervals along a circumferential direction; damping balls are arranged in the strip-shaped sliding holes in a sliding manner; an inner diameter of each strip-shaped sliding hole is smaller than a diameter of each damping ball; an outer diameter is greater than the diameter of the damping ball; and the strip-shaped sliding holes in the two sides of each damping ball are filled with damping rubber, a containing groove used for containing the damping balls is arranged in the inner wall of the shell, an assembling groove is arranged in the outer side wall of each wire joint, a damping ring is arranged on the outer side wall of the assembling groove, and a limiting groove abutting against each damping ball is arranged in the side, away from an end portion of the wire, of the damping ring. Automatic locking of the wire joint and the conductiveconnecting mechanism is realized, a torsion acting force of the wire is weakened, and the wire is prevented from being broken by torsion.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a wire connection device and a method for using the same. Background technique [0002] When the conductor length of the overhead transmission line is not enough, or the conductor is worn and broken, it is usually necessary to use a connecting device to connect the two conductors together. Due to the influence of weather conditions such as wind and snow, the wires are prone to fatigue vibrations in multiple directions, such as breeze vibration, ice-covered dancing, etc., which may easily cause wire breakage. However, the existing wire connection devices seldom consider the above problems, resulting in The wire at the connecting device is easy to wear and break again. In addition, to prevent the wire from breaking due to vibration, in addition to considering the vibration of the wire in multiple directions, it is also necessary to consider how to avoid stress concentration...

AI Technical Summary

Problems solved by technology

Due to the influence of weather conditions such as wind and snow, the wires are prone to fatigue vibrations in multiple directions, such as breeze vibration, ice-covered dancing, etc., which may easily cause wire breakage. However, the existing wire connection devices seldom consider the above problems, resulting in The wire at the connecting device is easy to wear and break again. In addition, to prevent the wire from breaking due to vibration, in addition to considering the vibration of the wire in multiple directions, it is also necessary to consider how to avoid stress concentration at the connecting device when the wire is subjected to torsion, causing the wire to break.

At the same time, the existing wire connection devices mostly use bolts to fix and clamp the wires, and the bolts are easy to loosen due to thermal expansion and contraction, causing potential safety hazards; and the connection speed is slow, which is not conducive to fast operation
