The utility model belongs to the technical field of copper strand, and discloses a copper strand with a pressure-free end, which comprises a copper strand section and a connecting end at both ends of the copper strand section, and the two connecting ends are integrated with the copper strand section. The copper strand does not need to install connection ends at both ends of the copper strand, nor does it need to be pressed. Only pressing and melting operations are needed at both ends of the copper strand. As a result, manual operation is saved. The pressing and melting operations in the utility model almost do not need manual operation. Workers only need to hold the copper strand by hand, which can effectively improve production efficiency. Secondly, because there is no need to purchase independent connection ends, a large number of sections can be saved. Compared with the test data, the temperature rise of the copper strand of the utility model can be reduced by 38.7% at most compared with the temperature rise of the traditional soft copper strand under the working condition of 600A, and the contact resistance is 0.276 of the contact resistance of the traditional soft copper strand. The copper strand with this integrated structure can completely avoid loosening or falling off of the end of the traditional copper strand connection and ensure the reliability of the copper strand.
【技术实现步骤摘要】
带免压接端头的铜绞线
本技术涉及铜绞线
,具体地,涉及一种带免压接端头的铜绞线。
技术介绍
传统的软铜绞线两端需要人工插入独立的连接端头,然后采用专门的压接工具进行压接使连接端头与线稳定连接,这使得成品铜绞线的制作工艺较复杂,成本较高。
技术实现思路
本技术解决的技术问题在于克服现有技术的缺陷,提供一种带免压接端头的铜绞线。本技术的目的通过以下技术方案实现:一种带免压接端头的铜绞线,包括铜绞线段和设于铜绞线段两端的连接端头,两个连接端头与铜绞线段一体化设置。进一步地,连接端头是先成型出连接端头体后再对连接端头体钻孔得到的。更进一步地,连接端头体的成型是在油压机和高分子扩散焊机中交替压制和熔压完成的,油压机上设有用于放置铜绞线端部进行压制的模具,模具内腔与连接端头外周适配。与现有技术相比,本技术具有以下有益效果:1)无需在铜绞线两端安装连接端头,也无需压接,仅需对铜绞线两端进行压制和熔压操作,一来节约人工操作工序,本技术中的压制和熔压几乎无需人工操作,工人只需手握铜绞线即可,可有效提高生产效率,二来因无需采购独立的连接端头,可大量节约成本;2)经试验数据对比,本技术的铜绞线在600A的工况下,温升最多比传统软铜绞线的温升降低38.7%;3)本技术的铜绞线的接触电阻是传统软铜绞线接触电阻的0.276;4)这种一体化结构的铜绞线可完全避免出现传统铜绞线连接端头松动或脱落的现象,确保铜绞线的工作可靠性。附图说明图1为实施例1所述的铜绞线的结构示意图;图2为实施例1所述的连接端头体的成型流程图;图3为实施例1所述安装于油压机上的模具的上模、下模结构示意图。具体实施方式 ...
