THT components on Aluminium PCB
« on: August 20, 2026, 01:15:02 pm »
Hi,

The picture is from a teardown of an LED lightbulb by youtuber diodegonewild.
It shows some sort of adapter to allow THT components to be used with aluminium PCBs (see arrow).
What is the correct name for this THT to SMD adapter?
Where can i find these?

Thanks
Matthias

Here's another pic on the connector... I presume you're interested in the white connectors on the left side of the board.

It appears at around 9:50 in this video:

Found this similar looking thing... "SMB PCB terminal block" might be the description:

20pcs 2 Pin SMD PCB Terminal Block 3.0 mm Pitch 2 Ways 26 to 22 AWG Clamp Push Wire Tin Plated 3A 250V Rating Wire to Board

This one seems to have its wire connections horizontally, on the placement  side.
It would be more interesting to have the wires come from the other side of the board.

Thanks, "bottom entry" is kind of half way what i was searching for, if no specific name exists.
However at the usual parts suppliers websites, i could only find bottom entry terminals/headers/sockets, that accept other/male headers with very strict dimensions. Nothing that is flexible enough for random THT wire sizes.

That seems to be a similar part. But i am kind of lost with the chinese language. It seems to just say "LED connector"?
I cannot find anything remotely similar  on mouser/digikey/lcsc, etc.
