AI Technical Summary

Technical Problem

The existing alignment screws have low processing efficiency in the production of submarine optical fiber composite cables and cannot meet the high precision requirements.

Method used

A high-precision alignment screw for the production of submarine optical-electric composite cables is designed. By processing the screw and nut separately and pre-processing the snap-fit ​​groove and through hole in the fixing part, the screw and nut are connected through the positioning hole and through hole. Combined with the return spring and positioning part, a stable connection and anti-loosening effect are achieved.

Benefits of technology

This improved the machining accuracy and production efficiency of the alignment screws, ensuring the product quality of the submarine optical fiber composite cable and preventing thread stripping.

Abstract

This utility model provides a high-precision alignment screw for the production of submarine optical fiber composite cables, relating to the field of alignment screws. The high-precision alignment screw for submarine optical fiber composite cable production includes a screw, a nut, and a fixing part for connecting the nut. The fixing part has at least a retaining groove for accommodating the nut and a through hole for accommodating the screw. The screw is threaded into the nut, the nut is engaged in the retaining groove, and the screw portion is fitted into the through hole. The nut surface has a positioning hole perpendicular to the screw, and the side wall of the retaining groove has a through hole coinciding with the positioning hole. This high-precision alignment screw for submarine optical fiber composite cable production allows for the separate processing of the screw and nut, with the retaining groove and through hole pre-machined during the fixing part's processing. The nut is then assembled into the fixing part, enabling the two parts with significantly different processing precisions to be processed separately, thereby improving production efficiency.
