meh, my pcb wont fit anyway. maybe i need to think more on how to mod the 2 upper connector/adapter... (attached) but more creative and artistic works.

if only i know the keyword. i tried to search "bnc adapter |connector | pcb | probe" in aliexpress and got dissapointed, added with my ISP having bad days lately making surfing experience abysmal.

what kind of bulkness the bulkhead is? if its just 2 connectors back to back, then no. i need something i can put a small pcb inside, the closest thing is shown by Richard, and the not so brilliant "stripping from china probe" solution as suggested by odgen (and was my idea too)

fwiw, the 2nd attachment is my current prototype using the middle adapter on the 1st pic, but the pcb wiggles too much and surely easy to snap during normal usage. and the thread make it significantly longer than it should be. the more compact the better but well, maybe someone will ask... custom design your adapter and send to fab house... $$$

Ohh, tiny. Yep that's a bulkhead fitting.  :-+
OK that gives a really good idea of what you need.  :)

as you see in 1st attachment of my last post, i have a bunch of that, one shown on the top picture among the 3 connectors. i think i've finished browsing for "bnc connector" in aliexpress without finding even close to what i expected in the OP. one of it maybe this, as an idea...

it has that whitish silicone where we can lay and glue the pcb on, less wiggling i suspect, and the connector body seems easy to solder to a custom shaped metal to cover the pcb and coax cable. but unfortunately its the female bnc. if its male it will be nicer than the picture you showed. the one you showed, it needs more special shaped metal to fit in due to  the 4 "spokes". maybe i can break those if no other better alternative. and find squared U (custom made) shape metal to solder together, my CNC is under construction, when completed? i dont know. ;D

BravoV:
Or if your PCB and the components can be squeezed into really small, other alternative, those cheap metal BNC 50 Ohm feed thru terminators.

Pretty sure with your creativities shown above, you can cut the middle pins and soldered a pcb with components on it.

Its plenty at AliExpress, and the metal quality is pretty decent.



Once unscrewed, the inside
