Description

电力机车光电连接器 技术领域
本发明涉及电力机车技术领域，尤其涉及一种电力机车光电连接器。
背景技术
电力机车按牵引电动机的性质可分为直流传动电力机车和交流传动电力机车两大类，前者采用直流牵引电动机，后者采用交流牵引电动机。交流传动电力机车的交流传动系统包括功率模块，功率模块的驱动信号的正确性是保证功率模块和整车系统安全可靠工作的决定性因素。驱动信号的正确性与可靠性不仅受牵引变流器控制单元(Traction converter Control Unit，简称TCU)中软件控制算法的影响，同时也受驱动信号传输方式和传输路径的影响。驱动信号的传输方式可以是光传输或电传输，相应的传输路径分别为光纤或电缆。光纤相较于电缆抗电磁干扰能力强、传输速度更快，因此现有的交流传动电力机车大部分都将电信号转化为光信号进行传输。
现有交流传动电力机车直接使用线缆将TCU和功率模块的驱动板连接。由于驱动板的位置比较隐蔽，当驱动板出现故障或需要检查维修时，首先要拆除驱动板的连接线，但受安装空间的限制，驱动板上的连接线难以直接拆除。现有技术中通过拆卸功率模块，然后拆除驱动板上的连接线，最后再从功率模块上拔下驱动板，拆卸功率模块不仅增大了拆卸维修难度，而且增加了维修成本。

本实施例中，可以将第一接头的第一端11的边沿设置为锯齿状，将驱动板的相应位置设置为与第一接头的第一端11的锯齿状边沿相配合的锯齿状，可以避免第一接头的第一端11与驱动板之间出现滑动，并且在第一接头的第一端11设置连接孔，采用螺栓将第一接头的第一端11固定在驱动板上，防止第一接头的第一端11与驱动板之间的连接松动或断开。第二接头的第一端21与TCU的光纤和电缆连接后，采用线缆夹固定光纤和电缆，防止拉伸光纤或电缆时导致第二接头的第一端21与光纤或电缆之间的连接松动或断开。
当驱动板出现故障或进行检查维修时，只需要将光电连接器的第二接头拆除，断开第一接头与第二接头的连接，即可完成驱动板上的连接线的拆除操作，由于光电连接器的第一接头与第二接头可拆卸连接，便于拆卸，从而解决了现有技术中受安装空间的限制，只能先拆卸功率模块，才能拆除驱动板上的连接线的技术问题，降低了拆卸维修难度，减小了维修成本。

可选的，第二接头的第二端22上设置有限位装置。通过限位装置，使得第一光纤连接头141、第一电缆连接头142与第三光纤连接孔241、第三电缆连接孔242分别对应，避免出现连接错误，例如，第一光纤连接头141插入了第三电缆连接孔242，第一电缆连接头142插入了第三光纤连接孔241的误插。限位装置还可以避免第一光纤连接头141、第一电缆连接头142与第三光纤连接孔241和第三电缆连接孔242由于过连接被损坏，以及防止连接头与连接孔的对接出现偏差，影响光电连接效果。可选的，限位装置为限位槽或止挡板。
