Dual stacked combo dsub connector needed [message #169323] Thu, 09 February 2017 16:30 Go to next message

I am looking for an Eagle symbol and footprint for dual stacked combo dsub connectors, specifically Norcomp 179-009-413R571 which is a right angle DB9/DB9 plug/receptacle with female gender lower and male upper.
Typically these dual stacked DB connectors have their upper connector pin positions further away from the board edge than the lower connector.  The upper set are located at the same distance from the board edge as as a version of a single DB connector with deeper backset distance.  So it would be possible to just take an existing single DB connector with deeper setback footprint and use that.

The lower connector also has a footprint matching a single DB connector with closer backset.  However, its mounting holes are aligned with the row of pins nearest the board edge instead of centered between the two rows (as in standard for single DB connectors).

Hi Steve,

I don't know if there is such a part buried in the existing EAGLE libraries somewhere as I don't use them. If you've found a similar single connector you could start with that, copy it and then modify it to match your dual stacked connector.

Alternatively, and IMHO the better way, is to just go ahead and create the library part yourself from scratch. Looking at the data sheet you linked it gives the recommended PCB footprint with all the dimensions needed so it will be fairly trivial to create from scratch. Are you familiar with creating EAGLE library parts yourself? If you aren't then go through the manual and look at some online tutorials. Adafruit and Dangerous Prototypes both do some reasonable guides to get people up and running with creating EAGLE libraries and there is always lots of help in these forums if you get stuck.

Best Regards,

Rachael

Check the con-subd library. Maybe you con modify something from there.

Hi,

search for con-subd.lbr in the library - there you'll find a connector from NorComp.
Then there search for 182-009-MALE as reference.

This allows you to build your connector with the given drawing diagram.
(You can also copy it into your created lib file.)
This reference helps in dimensioning and drawing the required reference lines.
With these reference lines, you can set your footprint also the limit of this housing.
Tip: You can draw your reference lines in a separate new layer and also switch between the grids.
You need more than a 0.318 " grid (eg layer 200 or whatever you want ...)

Sometimes it would be faster to create your own device and footprint.

Regards,
Gerald

Hi Joern,
Yeah, you was a little bit faster....B-) I wrote at the same time as you posted.

Any pointers on how within the one component to have two sets of pins 1 through 9, one for top and one for bottom instead of pins 1 through 18 ?  So the references end up something like X1T-1..X1T-9 and X1B-1..X1B-9 ?

Hi Steve,

You can just name the pins T1 through T9 and B1 through B9.

Best Regards,

Rachael

Hi Gerald, no problem ;-
I just delivered a tip but you almost delivered the whole thing ;-)
But - reading further down the thread it all seamed for the birds...
