Abstract

本实用新型涉及一种用于通信用户终端设备到电缆分线箱(盒)之间的室内外敷设用绞合双芯铜包钢电话用户通信线。它是由导体芯线、绝缘层及护套组成的通信线，其导体芯线的外层挤包绝缘层，两根带有绝缘层的导线扭绞成一股置于护套中，其绞合节距为70—150mm。本实用新型在不增加体积重量的情况下，使得线路的通信质量大大提高，并大幅度地降低了电话用户通话中串音、杂音干扰及音量衰减的弊端，并符合国家标准。

Description

绞合双芯铜包钢电话用户通信线
本实用新型涉及一种用于通信用户终端设备到电缆分线箱(盒)之间的室内外敷设用绞合双芯铜包钢电话用户通信线。
目前，广泛用于通信用户终端设备到电缆分线箱(盒)之间的室内外敷设线及电话用户室内敷设通信线多是采用两根导线平行置于护套层中的结构，即双馈线。但在使用中由于电缆结构所至，常会出现串音、杂音干扰等现象，影响通信质量。
本实用新型的目的是，减少通信传输中的串音及杂音干扰，提高通信质量。
本实用新型的技术解决方案是，由导体芯线、绝缘层及护套组成的通信线，其导体芯线的外层挤包绝缘层，两根带有绝缘层的导线扭绞成一股置于护套中，其绞合节距为70-150mm。
本实用新型的优点是，绞合双芯铜包钢电话用户通信线在不增加体积重量的情况下，使得线路的通信质量大大提高，并大幅度地降低了电话用户通话中串音、杂音干扰及音量衰减的弊端。
图1为本实用新型的横切面结构示意图；
图2为本实用新型的侧剖示意图。
由钢芯1和铜层2组成的芯线，在其铜层2的外缘均匀紧密地挤包0.6mm的绝缘层3，两根挤包了绝缘层3的导线按照70-150mm的节距扭绞后挤包一层厚度为0.7mm±0.05mm的护套4中。
