Connector types to used to distribute AC mains terminals
I want to power tens of these small power supplies. From a single AC mains.


The model you have linked is intended for mounting on a PCB. Normally you would use the PCB to handle the power distribution.


  For example I found this terminal block under the category called "distribution blocks". But in its data sheet there are types for earth and neutral but not line.


The block you link to seems to be available in black, blue and green. It seems that the black version is intended for phase, the blue one for neutral and the green one for earth.

From looking at the pictures and the description as a "distribution terminal block" I am pretty sure that all the terminals are connected but i'm not 100% sure on that.
