If you’re asking about what’s on the ends of the wires, those are ferrules, sometimes called crimp pin connectors. A very common way to make a connection if you don’t want to just use a bare wire. If you mean the connector on the RoboRIO, see @bobbysq’s answer above.
If you’re asking about the inset recepticle on the roborio , one of them is USB B Male.
Maybe you should circle what you’re talking about in the picture.
Thank you
Alternatively, check out Phoenix Contact 1966091 (octopart link). It fits the same port but has a push-in spring connection style instead of the screw terminals which are not ideal in high vibration applications. Unfortunately you lose the printed “V” and “C” if you switch to this connector so you need to keep track of the connector’s polarity a different way (e.g. make some sharpie marks on the rio body).
Do you have a diagram to wire the RIO with the POE?
I strongly suggest checking the rulebook before using POE to power the RIO, at least for competition purposes. R615 doesn’t allow that method.
YET.
I wouldn’t bet on how much longer it’s not legal. I also wouldn’t bet on it being legal without extensive testing (which appears to be in progress).
I don’t think it’s actually an R615 problem, since that really just deals with where the power comes from, not how it’s transmitted. It does violate R622, though.
Unless the ethernet cable uses 18AWG or larger… R623 to assist there.
I was looking at R615 for a “source/end” sort of deal, but you’re right about it not applying here.
It definitely violates R614. I’m running this RIO at 48V because I’m a spec following madman!
I can do you one better. I can give you the spec. This bad boy is 802.3 AF. Good old IEEE. Rocking it hard with these insanely high and unsafe voltages.
Edit: It’s early and this joke is going to go over heads. The RIO cannot take a raw 48v input. This is an actual POE adapter (not whatever we use in FRC that we call POE but it isn’t) for a 12v output (hit up the great rainforest in the sky). I’m using it for powering my development RIO from a switch. This can’t go on a robot legally. RJ45 is an awful connector for power delivery and only superior to barrel jacks on FRC robots in my opinion.
And if OP is asking about those ferrules and OP’s tagline is always questioning “What could go wrong?” then be aware that bare wires almost always give much better mechanical and electrical connections than ferrules since bare wire conforms to the connector; ferrules and tinned wire do not (just watch out for “hairs” sticking out and shorting to nearby material).
I was wondering for powering to run the RIO for bench work
And if you believe OP is really bad at framing a photo (it happens), then there is the CAN WeidmĂĽller OMNIMATE Signal - series LSF LSF-SMT 5.00/02/180 3.5SN BK TU
Referring specifically to the PDP cage clamp spring terminals (iirc WAGO?), square ferrules maintain the wire size rating of bare multistrand. Round or octagonal ferrules should be considered solidcore and derated by 1 wire size.
(eg consider 12AWG with round ferrule equivalent to 14AWG solid core for cage clamp terminal ampacity, but 12AWG with rectangular ferrule is 12AWG.)
I suspect this is generally true across the board, not just that single part series.
Ferrules make it so much easier to handle multistrand, prevent “loose hairs” developing during wiring harness install (inspect at external subassembly step), and guarantee known insertion depths during install… I’d never leave them out of a robot/control cabinet design at this point, the reliability gains from making it easy for my final assembly people to build things right are almost always more critical than X% better conduction through any particular terminal.
In FRC specifically, we also have 10+ minutes of cooling time between 2.5 minute matches on a back to back eliminations run, and more commonly 40+ minutes.
Ferrules purchased from sources such as Amazon can vary significantly in quality, depending on the seller. Some work fine. Some are made from inferior materials so they don’t hold the wire properly so it slips out at inopportune times.
Ferrules purchased from “professional sources” that are focused on serving electrical/electronic manufacturers (DigiKey, Mouser, Newark etc.) will be of high quality and will work properly if the correct part is chosen.
And that’s almost an understatement! That’s why we use them except not on the motor circuits of Power Distribution. For those high power bare wire connections we plead with the students to be careful.
We do have problems with ferrules pulling out of connections and wire pulling out of ferrules. Maybe the problem is
I thought we had good ferrules and the crimper is expensive; will have to investigate more.
