Need to be able to terminate 24 cores inside a plastic projects box ...

Lid of box will have display circuitry ... base of box will have
incoming signal cables ...

It makes sense for this connection to be pluggable ... although it would
only be unplugged in event of failure and need to repair.

Current is only a few mA at mains voltage.

One side of connector could be solder connection and one side screwed or
both screw fitting....
Could use something like :

Anybody got a neater way ...

is it 220V AC suitable, do you have a url ? or ref number

Funnily enough, yes! They are rated for operation at 250V ac.

I had a memory that they were and just wandered over to RS's website to
find a datasheet and confirm it.

Many are rated up to 300V RMS surprisingly.

I think there are issues that go beyond specified working voltage.

AFAIAA they have always had careful qualifications that they are not to
be used for mains interconnect and I am 100% sure that they do not meet
creepage and clearance requirements for mains connected equipment.

To earth or not to earth the shell? There's not enough C&C to meet class
II requirements and I'm not sure about making a D-type body and shell
safe at class I either.

Sorry to be offer only negatives without an alternative solution but the
split terminal block captive within a plastic enclosure may be the
safest way as the serviceable part could be attached to the front panel
and removed from the captive, mains connected cable termination.

I always thought they were comms rated .. suitable up to 48VDC ....
shows you can make wrong assumptions.

I'd plump for D connections every time. I've never known them to fail as
the can have jackscrews and good strain reliefs in the backshells.

They are also very good value due to the vast numbers made.

Similar to connectors used for ATX motherboards?

These are 600V max voltage,
