Problems solved by technology

[0002] At present, the wires of the power line are not connected by force, and the grooved wire clamp and the T-shaped wire clamp are widely used. The contact resistance of the grooved wire clamp and the T-shaped wire clamp is large, and the connection interface is quickly damaged by electric corrosion, and there are occasional power line burns and disconnection accidents. It is a weak link of the power grid and a hidden danger of accidents
In order to replace parallel groove clamps and T-shaped clamps, C-shaped clamps, H-shaped clamps, wedge-shaped clamps, shuttle-shaped clamps, stress clamps, wrapped clamps, etc. have been invented in the past ten years at home and abroad. Some of them have not been widely accepted and promoted for more than ten years because they have not completely solved the above-mentioned deficiencies in the prior art, and some have not been widely accepted and promoted because of inconvenient installation and disassembly, or because they are expensive.
Although wrap-through clamps have appeared in the past year, because the middle wrapping body of this wrap-through clamp is an integral part, this part is not only difficult to process, but also inconvenient to wear wires during construction. Especially when clamping thicker wires, it is almost impossible to fit the wires into the wire clamping groove, which limits its use and promotion

Embodiment 1

[0027] Example 1. Figures 1 to 3Shown: double-layer wrap-through parallel groove clamp, composed of parallel groove clamp upper splint 1, parallel groove clamp lower splint 2 and parallel groove clamp clamp bolt combination 3 formed by parallel groove clamp. In the clamping cavity between the upper clamping plate 1 of the parallel groove clamp and the lower clamping plate 2 of the parallel groove clamp, there are bolts passing through the clamping bolt combination 3 of the parallel trench clamp and the lower clamp 2 of the parallel groove clamp and the parallel groove line The upper clamping body 4 and the lower clamping body 5 of the upper splint 1 of the clip are installed together in series. On the left and right sides of the upper clamping body 4, an upper concave clamping line groove with an opening downward is provided. The left and right sides of 5 are provided with downward concave-shaped clamping lower grooves with upward openings, the clamping upper grooves and the ...

Embodiment 2

[0028] Example 2. Figures 4 to 6 Shown: the parallel groove line clamp described in this embodiment is a span parallel groove line clamp whose width between the left and right sides of the upper splint 1 is smaller than the width between the left and right sides of the lower splint 2 . Other structural features of this embodiment are the same as embodiment 1.

Abstract

The invention discloses a double-layer wrapping through-type parallel groove clamp, which comprises a parallel groove clamp formed by a parallel groove clamp upper clamping plate, a parallel groove clamp lower clamping plate and a parallel groove clamp clamping bolt combination. A clamping cavity between the parallel groove clamp upper clamping plate and the parallel groove clamp lower clamping plate is provided with an upper clamp body and a lower clamp body serially connected with the lower clamping plate of the parallel groove clamp and the upper clamping plate of the parallel groove clamp through bolts of the parallel groove clamp clamping bolt combination. Two horizontal sides of the upper clamp body are provided with upward concave clamp upper grooves with downward openings. Two horizontal sides of the lower clamp body are provided with downward concave clamp lower grooves with upward openings. The clamp upper grooves and the clamp lower grooves are buckled to form a clamp groove, and the clamp groove is located in a wire clamping cavity of the parallel groove clamp. The double-layer wrapping through-type parallel groove clamp is a power wire connection clamp which has the advantages of safe and reliable use, good connection effects, simple operation and low use cost.

Description

technical field [0001] The invention relates to a wrap-through type parallel-groove clamp for power line conductors to be connected without force, which is suitable for tension over-lead jumper connection, branch lead-out connection, distribution line in power transmission lines, distribution lines, and low-voltage lines of power systems. The down-lead connection of electric transformers, the down-lead connection of incoming lines, and various unstressed connections of power conductors for power distribution in substations and factories. Background technique [0002] At present, the wires of the power line are not connected by force, and the grooved wire clamp and the T-shaped wire clamp are widely used. The contact resistance of the grooved wire clamp and the T-shaped wire clamp is large, and the connection interface is quickly damaged by electric corrosion, and there are occasional power line burns and disconnection accidents. It is a weak link of the power grid and a hidd...
