Try JST. They have individual crimp contacts that snap into a board and
can be soldered. Handles up to 12AWG. They have other series of
"ganged" parts that handle 18AWG and smaller wires.

Subject: [TN] Is there a good discrete wire support still made
Many of the electrical paths in our products are power circuits
connected with 12, 16, 18, 20 AWG wire. Wires are sometimes soldered
directly to thru holes on our PWBs. This produces a connection using
the least amount of board space, but the wires are subject to handling
damage, with bird caging evident if the wires are flexed too often near
the solder joint. Finding inexpensive, small pin count, high current
connectors that incorporate machined pin contacts with 50u Au (aerospace
product with some flight critical applications) and don't use up board
area is difficult.
Before Burndy was incorporated into FCI, they had a product that could
be used to position and support wires entering into a PC board. I'll
call it a Wire Support. It looked like a connector body without
contacts installed. It had a one way barbed feature inside each of its
"contact" cavities so that you would slide a wire down into the body, it
would be held in place by the barbs, and the stripped end of the wire
would pass thru into the PWB hole, ready for soldering. It was
available in different position capacities, I think from 1 to 10 wires
in a row and it snapped into the PWB with some peg features built into
the molding. If someone out there has an old Burndy catalog you can
probably find it, I think it was towards the back pages.
This item solved a lot of problems, in that it is cheap, took up the
least amount of additional board area, pre-positioned the wire for wave
soldering and provided a means of strain relief to protect that delicate
area right above the solder joint. I've contacted FCI and they say the
product has long since been discontinued without replacement.
Does anyone know of a similar device or if some other company may have
picked up production where Burndy left off. Your help is appreciated.
Thanks,
Gregg
