Tether Quick Disconnect


(Svein H.) #81

Finished with the QD and used a 4-pin Wet Con. This gives me a extra twisted pair inside the enclosure. I splized a Y-split so i can have the other two spare pairs in another mini connector on the outside of the 4" enclosure if i in the future want to attach a sonar or water linked system. I installed one of the small 7-pin connector that Paul bought and showed us. i think it is a better solution to keep the splice as small as possible and to “hide” it in the sub. to minimize drag in the sea. there is also a bigger chance to get stuck it you have a big splice hanging behind you while flying around

Hi everyone.
I found it at a Japanese dealer.
They seem to be offering waterproof connectors already constructed.
It seems expensive but it is very interesting.

I bought a bunch of the season 2 pin connectors to use with the fathom x but for some reason cannot get my fathom x’s to talk to each other. any ideas?

Hi John,

Which wires in the tether did you connect the SeaCon connectors to? Are you sure the two wires aren’t being flipped somewhere in the connections?

Hi Rusty
I am away from my work base and cant recall exactly but I think I connected the brown wire to the black and white to white on an openrov tether.

just remembered that I had tried it also with just the connectors and no tether with same result.

The info on this forum is great - Thanks. I used the SubConn 8 pin splice with the Scotchcast. Then a SubConn bulkhead 8pin on the ROV. Went 1/64" larger than the 7/16 thread and it worked well. No issues using a drill press. In retrospect I am wishing I put a Kellem’s grip on like @SHS.

Hi Bluerobotics team,

Is there any expected release day for the BR quick disconect?

Regards,
LG

I have also tested this connector a few times now and they will do the job. I use this connector on my sonar and i had a dive to 100m for a few hours and i had no issues. It is important to mention that i overfill it with cilicone just to be sure that there will be no water in it.

Hi Mark, did you find a solution? Bulgin have circular connectors that are rated IP69k which is more than enough for your application, their standard series is actually tested to 100m for 12h:


(Mark Langille) #91

Yes we used the SEA CON 8 pin connector.


(Russ T. Bercle) #92

Hey are you able to give us more information on that stainless piece your tether secures to? (what it is, and how it fastens).
It looks really clean.


(Eloi Droniou) #93

Hi Rusty,

Any schedule for the release of a quick connect connector?

Hi Eloi,

Is a bit expensive, but the MCBH8F + MCIL8M works really nicely with the BlueRov 2

Hi Roy,
Are you using the Bulgin connector on the Sibius?
Thanks

Hello!

I figured I may chime in on some stuff I have done in the past for connectors. I used to work for SeaBotix where we used strictly Teledyne Impulse IE55 Connectors for small stuff, and SeaCon for all the others. We ran 2 ports for ethernet, 2 ports for Rs-232 and then the Tether.

Now I work for a company making quite a bit smaller gear Aquabotix, we are constantly trying to find low cost alternatives given we only go to depths of 50 meters, and are going for a low cost device.

Check it out here:https://aquabotix.com/

Lately I have been using the 10mm penetrator from BlueRobotics, and a PX0411 In-Line connector from Bulgin, I ditch most of the Bulgin parts and just hang onto the blue housing, trim the tabs off, and it slots into the penetrator perfectly.

PX0411 Connector: https://www.digikey.com/product-detail/en/bulgin/PX0411-08P-6065/708-1048-ND/1625813

I then use two types of epoxy, first a quick drying “no slack epoxy” on the back of the connector, sealing the pins and wires in place, as well as the housing into the penetrator. Then a longer set time “potting” epoxy through the back of the connector to seal everything up.

No slack epoxy: Loctite E-00NS

Longer Set Time Epoxy: Loctite E-60NC

I ran this setup in our pressure tank up to 80psi for 12 hours, we have also ran the connector down to 300 meter before with success. However, the pins are not very corrosion resistant, so you almost always want something mated to it. Especially if power is running to two pins.

There will be some more testing with these, I will bring you along as I know more.

Thanks,

Daniel

Impressive @danielbotix I’m going to have to try this… For the tether side, do you pot the back of the bulgin connector as well?

Awesome that you work for Aquabotix, glad those data/swarm divers are in good hands - one of the most fun projects I’ve ever worked on!


(Daniel Vandewiele) #98

@anthony-white Exactly that, I actually remove the provided rubber seal, seal the pins with the 00NS epoxy, and flow in the 60NC through the back of the completed connector.

Next try is with the new potting material that @rjehangir has released in the last few months. Just have yet to get my hands on some.

Great to hear from some original designers of these things! It’s a cool product.
