Description

同轴射频电缆
技术领域
本实用新型涉及一种电缆,具体说是一种同轴射频电缆。
背景技术
随着社会的发展,通信成为人们日常生活必须的一部分,同轴射频电缆作为通信信号的传输媒介,其质量和安全性越来越受到重视。现有同轴射频电缆采用实芯绝缘或单纯的发泡绝缘,这就使得它的使用温度范围较窄、机械性能差、耐热性能较差,因此现有同轴射频电缆在制作可靠的焊接接头时,或在温度较高时绝缘会发生变形,通信信号这时会发生产反射、失真或驻波,从而严重影响通信质量。
实用新型内容
发明目的:本实用新型的目的是为了克服现有技术的不足,提供一种能扩大使用温度范围、提高机械性能和耐热性能的同轴射频电缆。
技术方案:本实用新型所述一种同轴射频电缆,包括同轴设置的内导体、外导体以及外护套,外护套包覆在外导体上,在所述内导体和外导体之间设有氮气发泡电子辐照交联聚乙烯绝缘层。
通过电子辐照的方式使氮气发泡聚乙烯绝缘材料的分子结构发生变化,由线状结构变成网状结构,形成以氮气发泡电子辐照交联聚乙烯绝缘材料为绝缘层的同轴射频电缆。
氮气发泡电子辐照后的绝缘层有记忆效应,加热后不会变形,有效解决现有射频电缆耐温等级低、在制作焊接接头时绝缘会发生变形的问题,这就保证通信信号不会因同轴射频电缆变形而产生反射或驻波,从而提高同轴射频电缆的通信质量。
有益效果:与现有技术相比,本实用新型的优点是能提高产品质量,能耐受更高的环境温度,在进行制作焊接接头时不会发生产变形,通信质量高,稳定性好。
附图说明
附图为本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型作进一步的详细说明。
如附图所示,本实用新型同轴射频电缆,从内到外依次由同轴内导体1、绝缘层2、外导体3以及外护套4组成,内导体1采用外径为1.8mm的镀银铜线,外护套4包覆在外导体3上,在内导体1和外导体3之间设有绝缘层2,绝缘层2采用氮气发泡电子辐照交联聚乙烯绝缘材料;外导体3选用氩弧焊波纹铜管,该氩弧焊波纹铜管是采用厚度为0.25mm铜带通过成型装置卷成铜管,管缝采用氩弧焊接,再在铜管外表面轧制均匀的波纹制成,这样可以提高电缆的弯曲性能;外护套4为聚乙烯护套。
以上所述仅是本实用新型的优选实施方式,应当指出,对于本领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干变型和改进,这些也应视为属于本实用新型的保护范围。
