screw down PCB terminal blocks?
(1/6) > >>
coppercone2:
Do they have any terminal blocks that you solder to a PCB but you also screw down with side holes so they are tight ? These things are always wobbly and are kind of shitty

For high current screw connect to PCB, individual terminals are better. These have several PCB pins down thru the PCB 

  search for "high current screw PCB terminals"

Old line connector vendors like AMP and Berg and others made these,

Alternative is the German screw term like Wiedmuller,

in 1990ss. we used AMP  in  30A arc lamp PSU.

nah I don't mean high current. I just mean so the plastic bit is screwed down. Purely a mechanical improvement.

There is a spring thing embedded in the plastic. you solder the spring down. I want the plastic to be screwed down. Even if only with m2 screws

there are tons of connector housings that are totally garbage because the plastic bit ends up coming off, even with header housings. I have seen it happen in brand new commercial products too.

like if you put a flange on the bottom with screw holes. A metal connector has this, like a DSUB, its screwed down to whatever with alot of them, directly on the PCB. But I want screw terminals or spring terminals that have this, with plastic, since their not shielded.

I don't mean the wire, I mean the receptacle. Its so janky 
coppercone2:
like this thing. dr moreu connection. and I mean one piece, not one you disassemble the headers from.
