Home made feed through terminator for BNC

<< < (5/7) > >>

vindoline:
I'm interested in making up a set of these DIY terminators. However, all the BNC jacks and plugs in my parts box have different thread sizes  :-//. The jacks are 3/8" and the plugs are 7/16. Can anyone point me towards comparable parts?
Thanks a lot!

Just here to resurrect this thread a bit and maybe inspire others.  :)

I also built this DIY feedthru terminator. Firstly, because I needed to get clean signals from my fun gen and secondly it was a cheap solution.
I put two Bourns 100ohm 1W (2512) resistors in parallel to minimize stray capacitance and I also 3D printed some plastic sleeves that go around the BNC connector and labelled it so that it looks like a bought one.  :D
Here are some pictures of what I did...
Overall, this was a successful project.

BravoV:
Nice !  :-+

I ended with buying cheapo but full metal BNC 50 Ohm straight thru terminator at Aliexpress  ::), physically not bad imo, posted -> HERE

Very nicely done! I can tell from your pictures, though, how you made a electrical + strong mechanical connection between the two outer ("shield") conductors?

bjcuizon:
When I printed the plastic part, it did not fit over the male bnc just yet. So I had to sand down the inside just to make it fit tight enough. The female bnc locked tight enough too because I effectively eliminated the gap between the two connectors (as what the others have above in their pictures). So when I disconnect a bnc plug from the female bnc, it does not turn with it.

On the electrical side, the female bnc just screws into the male bnc. In that way, it just connects each other quite nicely.
