D Connector panel mounting methods

Does anyone have any suggestions as to good methods of panel mounting D
connectors for "through connecting" using premade cable assemblies?

Our situation is:

1) Rack mounted computers & associated equipment.
2) D connector patch panel on the rear of the rack unit.
3) Cables from the rack mounted PCs and equipment to the inside of the patch
panel.
4) Cables from the external side of the patch panel to other equipment
(monitors, controlled equipment, video projectors etc).

The problem is how best to implement the patch panel without manufacturing a
dedicated patch PBA with PCB mount connectors.

We have tried using gender changers mounted to the patch panel (0.9mm thick
S/Steel) and also kludge mounting the D connector plug (both M & F) to the
patch panel using a variety of screw lock nuts / spacers etc. Both these
solutions are a little untidy and have resulted in connectors occaisionally
not fully mating due to the added thickness of the patch panel. Use of 1mm
shorter screwlock nuts helps but then the problem is insufficient thread to
reliably retain the connectors.

This must be a fairly common situation - any ideas / solutions / advice
gratefully received.

TIA.

Welcome to the happy world of D-connectors on panels! :) Unfortunately

the custom PBA is probably the best approach - it's the one we've always
used in design lab's I've been at as it's tidy, easy and reliable. About the
only other way is to use a locking nut with an extra long threaded section
so that you can mount the D-conenctor externally and still have enough
thread left to put a nut and washer onto.

Cheers.

Do you really need the full D connectors ?

One approach is to use D to RJ adapters on the D connectors
on the PCs and then use standard RJ patch panels after that.

The main downside is that there are obviously less pins available,
but thats not always a problem that can be fixed in the D/RJ
adapter with some judicious looping of the D connector pins.

The mini industry basically just used 3 wire RS232
connections with software flow control and used RJ11
connectors with the 4 wires perfectly adequate.

Companies such as Altinex and Extron have mix and match solutions that may
be suitable, but at a cost.

Not quite pre-made, but you can get IDC ribbon cable D connectors that you
can mount to the external face of the panel. In onesies and twosies you can
get them from farnell, but they're made by 3M, AMP and just about everybody
who makes IDC ribbon cables and connectors in general.

Cheers,
Alf

Yes, IDC D's would be my first choice in such a situation. Just mount
them on the outside face and run the ribbon to the rack mount units.
Easy to cut just the right length of ribbon to keep things tidy too.
You can even get D punches that will cut a perfect hole in the panel,
not cheap though. But worth it if you are doing a few panels and want
a professional looking and quick job. So you could do a full custom
panel yourself in tens of minutes with a punch, IDC connectors, ribbon
and some mounting nuts.

I like the IDC's but some of the cables are SVGA and we are already
stretching the friendship with long cables introducing noise / xtalk etc. I
imagine going to ribbon may make this worse. We get the panels laser cut so
the holes are not a problem. Perhaps a through connecting PCB is the best
solution.

Break the SVGA signals into RGBHV and use BNC's - with the right cable and
connectors you can go 100's of metres.
