Abstract

本实用新型提供了一种铝基镀铜连接管,包括铝管,其特征在于,铝管一端内、外壁均包覆镀铜层。本实用新型的铝基镀铜连接管导电性能优良,电阻率<0.019,导电率是纯铜的95%以上。产品铜铝附着力受温度影响小,消耗铜材极少,优于传统铜铝连接管。

Description

铝基镀铜连接管
技术领域
本实用新型涉及一种电力金具中用到连接管,具体涉及一种铝基镀铜连接管。
背景技术
在现有的技术中,用于铜线铝线过渡连接用的连接管,在现有制造技术上多为为摩擦焊接、爆炸附铜、闪光焊铜铝对接、钎焊覆铜等。
摩擦焊、闪光焊存在铜消耗过大的缺点,几倍于镀铜的消耗量。
钎焊接头的耐热能力比较差、受温度影响大、接头强度比较低、钎焊时表面清理及焊件装配质量的要求比较高。
爆炸焊退火难,生产成品率低。材料来源难,机械化强度低,劳动条件差,爆炸时产生的噪声和气浪对环境有影响。
由此可见,电力行业中存在铜铝销量大,制造成本高,工业化程度低,工艺复杂、劳动条件差的缺点。
实用新型内容
为了克服上述技术问题,本实用新型提供了一种铝基镀铜连接管。
具体技术方案如下:
一种铝基镀铜连接管,包括铝管,其特征在于,铝管一端内、外壁均包覆镀铜层。
本实用新型的铝基镀铜连接管导电性能优良,电阻率<0.019,导电率是纯铜的95%以上。产品铜铝附着力受温度影响小,消耗铜材极少,优于传统铜铝连接管。
附图说明
图1为本实用新型铝基镀铜连接管结构示意图。
图中:1-铝管,2-镀铜层。
具体实施方式
下面结合附图对本实用型作进一步描述。
一种铝基镀铜连接管,包括铝管1,铝管1一端内、外壁均包覆镀铜层2。
最后,还需要注意的是,以上列举的仅是本实用新型的具体实施例子,显然,本实用新型不限于以上实施例子,还可以有许多变形比如:铝板、铝片、铝棒局部或是全部镀铜用作铜铝过渡为目的均为本实用新型的保护范围。本领域的普通技术人员能从本实用新型公开的内容直接导出或联想到的所有变形,均应认为是本实用新型的保护范围。
