J1939-11 physical connection on IEC terminal blocks?

Hi all,

At my shop, we have standardized using the Deutsch 3 way splitter and
connector parts for doing all our J1939 connections on our commercial truck
chassis.

However, we are doing very complex systems involving several nodes in a
small area.  To facilitate wire interfacing for the input / output and
power signals, we have started using IEC Din-Rail terminal blocks. However,
to date, we have not used these terminals for the J1939 connections.

My technician asked if he could use 3-level signal/signal/shield IEC din
rail terminal blocks, in which the shield terminal is connected right down
to the din rail.  The idea is that when there are several J1939 nodes being
installed in near proximity, we could use several of these 3-level terminal
blocks, and simply insert jumpers to interconnect them. Then, connected to
the last terminal would be a typical 120 ohm resistor.

Here's an image of this type of connector.  We have jumpers which push in
to interconnect any level to the terminal next to it.

This will allow us to bring the backbone into the panel, terminating it
only once at the first terminal rail.  the "jumpers" would now become the
backbone, with the nodes each only a couple mm apart.

Does anyone see any potential issues with this arrangement?

Thank you!
