AI Technical Summary
Technical Problem
The replacement of fuses in existing outdoor AC drop-out surge arresters is cumbersome, especially in high-altitude work scenarios where it is inconvenient to fix them with one hand and operate tools, which increases the difficulty of installation and poses safety hazards.
Method used
An elastic washer is installed between the lower contact and the nut, and multiple limiting tongues with arc-shaped and bent sections are designed to temporarily clamp the fuse using their elastic tightening force, simplifying the operation process.
Benefits of technology
It reduces the difficulty of operation in complex scenarios such as high altitudes, enables efficient installation by a single person, and improves the convenience and safety of operation.

Abstract
本实用新型公开了一种改进型的户外交流跌落式避雷器，包括内置有熔丝的熔管，熔管的两端分别固定安装有上触头和下触头，下触头的一侧设有跌落组件，下触头的顶部螺纹安装有用于锁紧熔丝端部的螺母，下触头和螺母之间可拆卸安装有通过自身弹力约束熔丝的弹性垫片。本实用新型通过在弹性垫片上设计多个带弧形段和弯折段的限位舌，并利用其自身弹力形成对熔丝的预固定结构。借助限位舌的弹性收紧力，熔丝穿入后可立即被临时夹紧，操作人员无需在旋紧螺母的同时用手持续固定熔丝，能直接松手取用工具完成最终锁紧，大幅降低户外高空等复杂场景下的操作难度，让单人作业也能高效完成安装，且结构简单，操作便捷，具有较高的实用性。
