[0029] Furthermore, a sliding groove 32 is provided at the connection portion between the outer wall of the fixed plate 31 and the sliding plate 2 , which is conducive to realizing the sliding control operation of the sliding plate 2 through the opening of the sliding groove 32 .

[0030] Embodiment 2

[0031] like Figure 1 , Figure 2 and Figure 4As shown, the utility model proposes a rail vehicle connector terminal that is easy to wire. Compared with the first embodiment, as another embodiment of the utility model, the bottom of the fixing plate 31 is fixedly connected with a spring 3 fixedly connected to the outer wall of the connector body 1.
