The invention discloses a novel signal trackside box which comprises a box support and a box arranged on the box support. A cable lock head is arranged at the bottom of the box, and a grounding gasket, a joint, a ground wire and an equipment grounding terminal are arranged in the box; the cable lock comprises a cable connector lug and two gland locking nuts, the two gland locking nuts are located inside the box, the cable connector lug is located outside the box, a grounding gasket is arranged between the two gland locking nuts and connected with a ground wire through a connector, and the ground wire is connected with an equipment grounding terminal. And the equipment grounding terminal is positioned on the inner wall of the box. The cable lock head is used for replacing the processes of cable end forming, protection pipe fixing, ground wire connecting, glue pouring and the like of a traditional box, the installation process is simplified, construction time is shortened, and installation efficiency is improved. The grounding gasket in the cable lock head is used for replacing a traditional box grounding mode, the installation difficulty is reduced, the connection firmness is improved, and the sealing performance of the box is improved.
本发明公开一种新型信号轨旁箱盒,包括:箱盒支架和箱盒,箱盒设置于箱盒支架上;箱盒底部设置有电缆锁头,箱盒内部设置有接地垫片、接头、地线以及设备接地端子;电缆锁头包括电缆接线头和两个压盖锁紧螺母,两个压盖锁紧螺母位于箱盒内部,电缆接线头位于箱盒内部外部,两个压盖锁紧螺母之间设置有接地垫片,接地垫片通过接头与地线连接,地线与设备接地端子连接,设备接地端子位于箱盒的内壁。使用电缆锁头替代传统箱盒的电缆成端、保护管固定、地线连接、灌胶等工序,简化了安装工序、缩短了施工耗时、提高了安装效率。使用电缆锁头内接地垫片替代了传统箱盒接地方式,降低了安装难度,提高了连接牢固度,增加了箱盒密封性能。
