The invention discloses an auxiliary power supply interface box for unpowered loopback of a locomotive. The auxiliary power supply interface box comprises a case assembly, a connector assembly and a switching control assembly; the case assembly comprises a case body, a cover plate is fixedly connected to an opening in the front portion of the case body, a sliding cover is attached to the back face of the cover plate in a sliding mode and is limited through a sliding cover limiting support arranged on the back face of the cover plate, a threaded lock is arranged on the cover plate, and a connector mounting plate is located in the case body, is parallel to the cover plate and is fixedly connected with the case body. The connector assembly is fixedly connected with the case body and the connector assembly mounting plate; the switching control assembly is fixedly connected with the box body and the cover plate. The unpowered loopback auxiliary power supply interface box of the locomotive is controlled to be opened or closed by adopting the same key as a locomotive pantograph operating system, the interface box cannot be used when the locomotive is normally dragged, namely the pantograph is lifted, the interface box can be opened and used when the locomotive is unpowered loopback, namely the pantograph is lowered, and the auxiliary power supply interface box has the advantages of being high in safety, high in operability, easy to maintain and compact in structure.

    本发明公开了一种机车无动力回送辅助供电接口箱,包括机箱组件、连接器组件及转接控制组件;所述机箱组件包括箱体,盖板固定连接在箱体前部开口处,滑盖与盖板背面可滑动贴合,并通过盖板背面设有的滑盖限位支架进行限位,盖板上设有螺纹锁,接插件安装板位于箱体内,接插件安装板与盖板平行设置且与箱体固定连接;所述连接器组件与箱体及接插件安装板固定连接;所述转接控制组件与箱体及盖板固定连接。通过与机车受电弓操作系统采用同一钥匙,控制机车无动力回送辅助供电接口箱开启和关闭,在机车正常牵引,即升弓时接口箱无法使用,在机车无动力回送,即降弓时接口箱可开启使用,具有安全性高、操作性强、维护简单、结构紧凑的优点。
