#1 Best approach to new terminal blocks

Hi there, I am uncertain of the best approach to represent this diode terminal. So far I have just made a custom block and have avoided the terminal strip features for the most part because we are experimenting with letting the electrician have the freedom to wire according to our schematic as he sees fit. In this case, we have a flyback diode terminal that needs to be shown on the schematic. We think we at least need to show the electrician that +V is on the top rail of the terminal and that all the 0V will be on the bottom rail with a jumper between all of the bottom terminals for all these outputs.

 

Should I continue this approach or create a custom two-level terminal for this part and use a terminal strip? I would need to make a diode terminal graphical block I believe. And if so, is there a specific approach to block creation for terminals that would work best for me?

Thanks!

well...

Thanks for posting on the forum.

You're best approach would be to define a stacked terminal and make sure the top junction is set to none-flow through.  You can then save that terminal part ot catalogue for future use.

As for the symbol used, it also will need to be defined as 'none-flow through', so your best bet is to open the 'Fuse terminal' (which you can fine in the 'Fuses' library folder) and modify it to fit your needs.  (The fuse terminal symbol is nothing more than a terminal symbol that will create a none-flow through terminal once you insert it on a schematics.)

Let us know if it works out, or if you need more information.

I think I need more

I think I need more information to figure this out. How do I modify the terminal fuse block to become a stacked terminal? I guess I don't understand the stacked terminal features enough or how to use them / integrate them with schematic symbols and what we are trying to do here.

Btw, don't know if it helps but my client drew this up as a potential option to consider. I'm not sure he wants me to invest more time here trying to figure out how to do this better but wanted to still ask before I drew this up and moved on.

Ah, ok...

Thanks for the added screenshot.  It does help us understand.

(We thought the diode connection was on the top section of the terminal, in the same fashion a fuse terminal is.  But we clearly see that the diode actually connects the two levels together.)

In that case, the fact the terminal is a diode terminal is not relevant from a SkyCAD standpoint: even if the top and bottom levels are connected through a diode, wire numbers should be different between the top and bottom anyway.  So a standard two level terminal will do the trick.

As for the way to represent it, you would need to insert two terminal symbols, one for each level, and stack them together after they're inserted.  (And then assign the part-number.)  You could still modify  the symbol so that is shows it's a diode terminal.

This tutorial about stacked terminals should help you learn more about how to manage this.

Let us know if this helps.

This helps out! Thank you.

This helps out! Thank you.

 

I am a little unsure of how I want to modify the symbols so far. Since it is two terminal symbols linked together for a stacked terminal it doesn't look straightforward. Should I modify only one of them to have a line "hanging off of it" to the other which would really just mean they appear that way even though they are two separate symbols?

 

I drew this up that I attached, is this what you have in mind? The lines between the symbols are just drawn on the sheet however at this moment.

Hmmm....

Sorry for the late reply.

This is most certainly a valid way of doing this.  We actually don't see a better way than this for now.
