A crimping device for steel-cored aluminum stranded wire

Abstract

The invention discloses a crimping device for steel-cored aluminum stranded wire, which comprises a first installation ring, a second installation ring arranged under the first installation ring, and symmetrically arranged on one side of the first installation ring and the second installation ring. The sliding rod, the crimping barrel is clamped between the first installation ring and the second installation ring; there is a slider on the slider, a hook on one side of the slider, and a connecting buckle on one end of the pressure rod; the upper slider The lower end of the block is provided with a first snap ring, the upper end of the lower slider is provided with a second snap ring, a connecting device is provided between the first handle and the second handle, and the stranded wire body is arranged on the first snap ring and the second snap ring between. In the present invention, the crimping barrel is clamped inside the first installation ring and the second installation ring, and a slide bar is arranged on one side of the first installation ring and the second installation ring, a slide block is arranged on the slide bar, and The upper part is equipped with a pressure rod, which is used to push the slider to gradually push the stranded wire body to the inside of the crimping barrel, which ensures the uniformity of the force on the stranded wire body and reduces the technical difficulty of the construction personnel.

Description

technical field [0001] The invention belongs to the technical field of cable crimping, in particular to a crimping device for aluminum-steel-cored wires. Background technique [0002] Steel-cored aluminum stranded wire is made of aluminum wire and steel wire, which is suitable for overhead transmission lines. It has a steel "core" inside, and aluminum wires are wound around the steel core by twisting on the outside; the steel core It mainly plays the role of increasing the strength. The aluminum stranded wire mainly plays the role of transmitting electric energy. During the crimping operation, one end of the stranded wire needs to be inserted into the crimping tube and crimped to complete the connection and use, which is convenient for multi-wire connection or protective installation of the joint. . [0003] After retrieval, the Chinese patent authorization number is CN201320769786.4, which discloses a crimping device for aluminum-steel conductors for power conductor constr...

AI Technical Summary

Problems solved by technology

A kind of crimping device for aluminum steel-cored wire for power conductor construction in the above-mentioned patent has the following disadvantages: when plugging inward, it needs to be manually pushed for insertion, and uneven force may cause certain bending and irregular pushing of the twisted wire, and It is laborious to push manually, which has a certain impact on the continuous installation operation of multiple lines
