how to keep motor cables inside power expander

Any ideas on how to keep motor cables inside power expander? There is no clip and they keep pulling out.

#2

I’ve seen lots of things used, but they all share some characteristics:

  • The PWM cables are well secured by wire ties so that there is less strain on the wires.

  • The cables are protected from intrusion by other robots

  • The intrusion protection can be easily (re)moved to allow access.

Let us know what you come up with.

The Power Expander is equipped with a PWM slide lock. You will notice that on the top of the power expander (pictured here), there is an additional piece of plastic with a lip at each end centered over the ports. This piece can slide about .1’’ over the port openings and is designed to lock the cables in place.

i think the “extension cables” do not have the extra “lip” that the motor wires come with
therefore they will not be “locked” in place :frowning:
we just used long wires, so there isnt any strain on them
and it is also unreachable by any other robot

The longer extension cables don’t, but if you add a small 7" green/orange/white extension cable to the end, it will have the small “lip”. Unfortunately I cannot find them anywhere on the product page, so I’m assuming they are not sold any longer.

P.S. There is a picture of what the ends look(ed) like here: http://www.vexrobotics.com/media/catalog/product/cache/11/image/5e06319eda06f020e43594a9c230972d/c/a/cablekey-6.jpg
