Does anyone know if it exists a multi connector that fits on the channel servo pins on the navigator. I have split the esc from the Pi/navigator enclosure and uses a 19 pin penetrator from the Pi/Navigator enclosure to the PWR/ESC enclosure. I would like to be able to connect the 19pin cables to multi connector that I can push straight down onto the Navigator pins. Does anyone know if shuch multiconnector existst?
Hi @SDI -
I’m struggling a bit to parse what you’re asking…
The Navigator does have an alternative, more compact connector than the header pins for connecting ESC signals:
That only provides 8 signal output however… You could terminate the signal wires individually with header pins, or attach to one large 3x16 female header - but this wouldn’t fit through a 10mm penetrator hole.
If you’re asking about a subsea connector with many pins, typical subcon connectors max out at 8 pins in the “micro” form factor, but larger do exist - they are likely quite expensive! Blue Robotics is working hard on a subsea connector - it will also have an 8 pin max to start. Blue Trails Engineering has some options as well - the max pin count seems to be 6x.
Tony, thanks for the reply. I have a 19Pin bulkhead connector in the end of the 4” unclosures endlid. I want to solder the wires from the connector directly to a multi connector. There are off course no plans or ambitions to get the connector throgh the holes of the endlid. I want to use a multiconnector to ensure proper contact compared to plugging one by one. I just found 1*16 and that is sufficient, but 2x16 would give more support and better grip on the pins.
So you’re after a 2x16 0.1" pitch header pin connector? You’ll want to make sure the ESCs all have their signal wires connected to ground, but this could be in the ESC enclosure and reduce the connections required. I use octopart to hunt for parts like this! The filters are quite powerful.
Thank you for the tip. yes the plan is to have all ESC to a common 0V connection point in the ESC bottle.
Another question while Im working on the subject. I removed the heat shrink jacket and the aluminium heatzink from the ESCs as I installed them in an oil compensated compartment. I tried looking on the BR site to see if I could find the spec for the heat-zink and silicone heat-patch without luck. I suppose I can just measure the free area and t find som heatzink online, but if the information is out thereI wouldnt mind having it. I slapped myself mentalley for not keeping the heatzink and pads, at least one of them. But little did I know that BR was to come with the nice 500m rated alu bottles…..Now I want to rebuild, away from the oil compensated version.
Hi @SDI -
Your approach to measure the necessary size is the correct one - Blue Robotics won’t have that information as the (current version) of the ESCs come assembled from a supplier. Therefore that information isn’t on hand! Best of luck!
Got you, thank you for letting me know.
