AI Technical Summary

Technical Problem

The existing cable joints are prone to gaps, and the heating equipment cannot effectively adjust the distance between the heating element and the cable joint, resulting in uneven heating or low efficiency, which affects the sealing performance.

Method used

A rapid sealing device for cable joints was designed, comprising a support ring, an adjusting ring, a telescopic ring, and a heating block. The device achieves synchronous clamping and positioning of the cable joints through a linkage mechanism. The heating block is set outside the telescopic ring to uniformly heat the plastic seal on the outside of the cable joint, and is suitable for cable joints of different specifications.

Benefits of technology

It improves the encapsulation efficiency and sealing performance of cable joints, ensures uniform heating, enhances sealing reliability, and adapts to cable joints of different specifications.

Abstract

This utility model relates to the field of connectors, specifically to a rapid sealing device for cable connectors. It includes a support ring, an adjusting ring on one side of the support ring, manual handles on both outer sides of the support ring, an elastic box on the outside of the support ring, a movable block inside the elastic box, and a telescopic ring extending through the elastic box. This utility model, through the linkage mechanism composed of the telescopic ring, the elastic box, and the movable block, can achieve synchronous clamping and positioning of both sides of the cable connector, improving sealing efficiency. A heating block outside the telescopic ring can quickly heat the plastic seal on the outside of the cable connector when needed, causing it to shrink evenly and improving sealing performance and reliability. The threaded connection between the adjusting ring and the support ring allows for flexible control of the position of the conical block, thereby driving the contraction of the telescopic ring, enabling the structure to adapt to cable connectors of different specifications.
