Good edge connectors and cables.
« on: 2017.March.17. 17:47:47 »
Some of the things that we Enterprise users most miss on our computers are good connectors. I'm not talking about the Expansion bus at the right side, or the cartridge bus, I understand why they where selected to be edge connectors.

But it is a pain to have that type of connector for the RGB, Serial, Parallel and Controllers ports.  If the user is handy he can make them itself by sawing a larger connector to fit, but then they have to be soldered to the leads, and this is more difficult.

But the worst it to make the connectors usable, I mean, they have to be easy to plug and unplug. The best is to glue the bottom face of the connector to a piece of printed circuit  and fix the cable to it with a plastic tie.

These solutions are far from perfect, usually the leads get broken and need to be re-soldered.

But now that I have the original Enterprise Mouse in my hands I can admire the strange beauty of its original connector....

The edge connector used isn't like what I usually cut, is a little wider and has a depression along it.

Then, the housing grips the connector with a claw on each side that matches that depression. Much the same like D-sub connector cases do.

I have found a make, Cinch that manufactured similar edge connectors. The product is outdated, of course.

But there are little stocks here and there...

I think that, once the connector is cut, a D-sub connector case can serve to make a good looking connector like the original. there are at least four or five sizes, from 9 to 15 pins that can suit.

But this isn't a new idea of me. The same Actec company used this cheaper approach on its Speakeasy box. Observe how the claws of the trimmed D-sub housing don't get to grab the edge connector channel. Maybe heating the claws with a lighter and bending them a little, the connector can be held on place.

Also there is the connector that can be found on RetroCables RGB lead, made with a 3D printer. Of course it is good looking, but doesn't fit very well on the socket. I had to trim it a little to fully enter in its place. Unlike the previous ones, this can be reversely plugged by accident, it has no blocking guide. Only a legend with the "UP" word prevent us.

The edge connector hasn't the channelled shape, probably glued to the housing with Cyanoacrylate glue.

But the most disappointing aspect is, although it makes very well its function, that the cable leads aren't individually shielded.

But for me the best connectors are those included on Werner Lindner's colection (technical director of ENTERPRISE Computers GmbH).

The housings consist of two simple halves, not the three complicated parts that the Patkány connector has. Also the shape is simpler, squared with lateral channels, filling completely the port hole. The edge connector is also hold in place by a claw on both housing halves, but not visible once mounted.

I can't see the way how the two halves are joined.





I would like to have samples of those connectors to clone them with a 3D printer, but I think it would not be difficult to know the measures, after all we have the computers to test.

Nice find! But you will still get sideways movement without glue?

I use a D-type shell but glue the edge connector (normal, without the recess) to the bottom half of the shell. I use Araldite Rapid, an epoxy that dries in an hour or two. It results in a sturdy connector that looks ok from the front or top but looks a bit rough in a magnified photo from the side! :oops: A black one would look nicer too but I already had a few old white D-types :oops: :oops:

Very good idea! You also can use some of the Araldite glue to mould the sides.

I will search for a variety of D-sub housings to build better connectors for my equipment.

One zx-pk.ru member made this connectors from COM-port bracket cases.
Uses glue. As for me - looks fine.

Yes, very good looking. At that blue light they are like Tron paraphernalia!


Observe the dimensions, they look big!

Another maker, actual, of recessed edge connectors.

I can't  find black connectors, only green.

Are they yours?

How are the two halves tied one to other?

I see that the ringed tube fits with a twist on the cilindrical tail, but one of the halves has an open slot.

Glued?

Is this a German or an original English design?

Who designed the Patkány connector? probably Aztec independently, I gess...

The drawing are the original English.

The unused connector cases, I don't know it is are German or Hungarian. (It is found in MICROTEAM basement :-) )
We bought serial cable about 27 years ago and it is have a same connector. As I remember the two half are glued and the ringed tube make it stronger. (We dismantled the cable for modify it to NET: connection).

I also guess it.
