Expansion type low voltage user line clip

Abstract

The invention discloses an expansion type low voltage user line clip. The expansion type low voltage user line clip comprises an M-shaped wire clip, wherein the M-shaped wire clip is provided with a left wire clipping groove and a right wire clipping groove which are provided with downward openings and are cutthrough from front to back; the left side and right side of the M-shaped wire clip are respectively connected with a connecting rod; the two connecting rods respectively extend to the front and back directions; the extending ends of the two connecting rods are respectively connected with an N-shaped wire clip; each N-shaped wire clip is provided with wire clipping grooves which are provided with downward openings and are cutthrough from front to back. The expansion type low voltage user line clip has the beneficial effects that the two parallel conducting wires can be fixedly connected, so that the quick fixing of the user line of a low voltage residential customer is realized; the operation time is short, the detachment is convenient, and the appearance is attractive.

Description

technical field [0001] The invention relates to an expandable low-voltage down-line clamp. Background technique [0002] At present, the down-home wires of medium and low-voltage residential customers in the power grid system are all bound and fixed by the terminal porcelain column binding back method, and the material used is a single aluminum wire. The binding process is: binding of butterfly insulators, binding of terminal porcelain posts. The operation process is: After coiling the binding wire into a coil, leave a short end at one end, the length of which is 5cm longer than the length after binding, wrap a circle around the binding wire, fold the short end back to the place where the wire is sunken, and then use a long After tying the wires for five laps, fold up the short end, continue to bind five laps, then repeat the above steps until the specified length (12cm-15cm), and finally twist the short ends for 2-3 twists to form a small braid and flatten it on the wire....

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. The process is cumbersome, and the binding wire needs to be bound at least 15-20 times on the binding wire

2. The preparation of binding wires is time-consuming. The binding wires are actually divided strands of power conductors. The smallest wire is composed of 7 strands, and the larger wire diameter reaches 20 degrees. It needs to be separated manually one by one, and then the binding wires are reeled. lock up

3. Affected by the diameter and strength of the binding wire, it is easy to break the strands during the binding process

4. The final binding effect of the binding thread is inconsistent

5. It is inconvenient to repair and replace. It is necessary to remove all the original binding wires before removing the lower household wires.
