The technical scheme that the utility model takes for solving the technical problem is:

A connection clip for live operation of a power system, comprising an n-type conductive slot, a terminal is provided on the outside of the rear arm of the n-type conductive slot, a support plate is provided at the lower end, a screw hole is provided in the middle of the support plate, and a screw hole is provided in the screw hole There is a screw, the upper end of the screw is fixedly connected with the circular wire crimping block, and the lower end of the screw passes through the screw hole and is spirally connected with the circular sleeve with internal thread; the lower end of the circular sleeve is provided with A telescopic rod, the lower end of the telescopic rod is provided with oblique anti-slip embossed lines.

The circular sleeve is provided with an upper circular hole and a lower circular hole, and the screw rod and the circular sleeve are fixed together through the upper circular hole and the fastening bolt.

The upper end of the telescopic rod is provided with an external thread, and the upper end of the telescopic rod is spirally connected with the lower end of the circular sleeve, and is fixed together through the lower circular hole and the fastening bolt.

The upper surface of the circular wire crimping block has an arc-shaped groove structure.

Both the circular sleeve and the telescopic rod are processed from high-strength insulating materials.

The positive beneficial effect of the utility model is as follows:

1. When the utility model is in use, first connect the terminal to the connecting wire, then screw the upper end of the insulating telescopic rod to the lower end of the circular sleeve, and fix them together through the lower round hole and the fastening bolt, and then adjust the insulation Extend the telescopic rod to a suitable length, then hang the n-type conductive slot on the overhead line conductor, rotate the insulating telescopic rod to rotate the screw upward, so that the round wire crimping block can press the wire tightly in the conductive slot, and then remove the insulating telescopic The rod is enough, safe and convenient to use, saving time and effort.

2. Since the circular sleeve and telescopic rod of the utility model are both processed by high-strength insulating materials, they can be installed without power off, without affecting the normal operation of the circuit, and have good practical value.

3. The utility model has the advantages of simple structure and convenient operation, which provides a strong guarantee for safe construction and has great market promotion prospects.
