The invention discloses a stray current friction welding of embedded terminals, including the terminal head and connected with the extension rod, the terminal head by the terminal end cap, anti twist flank and terminal head body, the terminal head body and the extension rod connection welded by heat, the terminal head copper terminal, extension rod for steel cylindrical rod, the terminal head body and the extension rod formed by reverse rotation friction welding, the setting terminal head with anti twist flank, the terminal end cap is arranged on the circumference of the groove. Further, the anti torsion flank has two symmetrical configurations, one end of the torsion proof flank is connected to the circumference of the end cover of the terminal head, and the other end is connected to the terminal head body, and the terminal head end cover, the anti torsion flank and the terminal head body are formed by one high temperature forging and pressing. The friction welding is stray current, the embedded terminal, the terminal body and the extension rod rotate at high speed, so that the terminals and the extension rods are connected to each other, and they are mutually reversely rotating and rubbing. They reach the high temperature quickly and reach the melting point, and then cool down to play the effect of friction welding. The integrated electrical and mechanical properties of the embedded terminals produced in this way are better.

一种摩擦焊接的杂散电流埋入式端子
本专利技术属于轨道交通设备领域,具体涉及一种摩擦焊接的杂散电流埋入式端子。
技术介绍
杂散电流排流网是杂散电流防护系统的重要组成部分,杂散电流防护系统可起到测量和收集杂散电流,并为其提供回流通道,将其引回变电所负极,尽可能减少杂散电流向地铁系统外泄漏的作用。杂散电流接地端子的作用是通过它与道床内部钢筋连接,从而形成杂散电流排流网。传统使用在地铁建设工程中的杂散电流接地端子主要是用扁铜加工而成,扁铜与钢筋结构之间通过放热焊的方式焊接在一起,扁铜两端的扁铜端子头露出混凝土,通过连接这些扁铜端子头部形成排流网。主要缺点有三个:一是扁铜与钢筋结构之间的焊接为放热焊接,需要现场施工,焊接点较多,放热焊接成本高,施工麻烦、不方便;二是露出地面部分的扁铜影响施工人员和维护人员行走安全;三是露出地面部分的扁铜无法防盗,容易丢失,一旦混凝土浇注施工结束,丢失的接地端子很难再弥补。杂散电流接地端子丢失,不能把全线的排流网连成一体,不能保证整个防护系统的完整性。
