connector: phoenix contact: add ffkds series

Joel Guittet requested to merge myfreescalewebpage/kicad-footprint-generator:myfreescalewebpage/phoenix_ffkds into master

Add FFKDS from Phoenix Contact. Here is a picture of one of the model (reference '1790335') and the associated footprint pushed.

Drawings: https://www.phoenixcontact.com/ and type "FFKDS" in the search bar.

This kind of connectors can be as large you want, just simply by clipping the base element shown above multiple times. Phoenix also provide some references with several base elements already attached together. There are 2 mains design, 4 pitches and 2 possible orientations (Horizontal and Vertical). There are also some references with different colors or marking.

The footprints are maybe not fully finalized, the general dimensions should be correct in my opinion (but need to be verified) but I need help to have another point of view on several subjects:

  • Is naming of the footprints correct ? I have copied from MSTB but there is no "rating".
  • How do you think the design is ? How would you expect the Silkscreen and Fab layers ? more details / less details ?
  • The base element, for example '1790335' (5.08mm pitch, shown on the picture above) has not the exact correct design because the right side has 2 or 3 pieces of plastic to attach the next element. Is this kind of details expected on the Silkscreen and Fab layers ?
  • I have tried to enumerate all the available references from Phoenix in "ffkds_params.py" but because the base element can be attached to create specific connectors, I suggest I should also create the footprints for all pins numbering 01x01 to 01x40 at least or maybe more ?
  • How to compute the pin clearance ? I have based this on MSTB series but I don't know which value to use for the small pitches. I need advice on this point.
