Abstract

The invention discloses a fully cold-shrinkable cable terminal, specifically relating to the field of power cable equipment, comprising a terminal main body, a stress cone is arranged inside the terminal main body, shed skirts are arranged on both sides of the terminal main body, and the stress cone A positioning frame is arranged inside, and the positioning frame includes a positioning collar, a sealing ring and a bump, and positioning devices are provided on both sides of the positioning frame. The present invention is equipped with a positioning frame and a positioning device, and utilizes the superior characteristics of rubber "elastic memory" before use to pre-stretch the terminal body of the manufactured cable terminal rubber part within the elastic range, insert it into the plastic supporting frame, and position it After the connecting plate of the device is placed in the positioning seat, the first telescopic rod and the tight plate are inserted into the inner side of the supporting frame, and the supporting frame is supported from the inside to ensure that the shape of the supporting frame will not change easily. Pull out the plastic supporting frame, and the rubber part of the cable terminal will quickly shrink and hug the cable, which is easy and convenient to operate.

Description

technical field [0001] The present invention relates to the technical field of power cable equipment, and more specifically, the present invention relates to a fully cold-shrinkable cable terminal. Background technique [0002] Since entering the new century, my country's electric power construction has developed vigorously, and the demand for electric power has also continued to rise. The demand for power cables in many fields such as metallurgy, construction, petrochemical industry, agriculture and daily life is constantly increasing. At the same time, the demand for cable accessories is also growing synchronously. In particular, the cable terminal head in the cable accessories can be connected with electrical equipment such as transformers and distribution boxes. It is widely used and plays a key role in the connection process of power cables. [0003] At present, a variety of tools are generally used in the installation process of cable terminals, and the process is rel...
