Terminal strip (chocolate block) where screws don't bear directly on wires

(1/2) > >>

perdrix:
I'm looking for some terminal strips where the screws bear onto a pad or something like that so they don't chew through soft wires (like tinned stranded wires).

I'm sure there's a special name for them but not knowing what that is, I've failed to find any so far.

Can anyone provide some pointers...

Thanks
David

Conrad Hoffman:
Do a Google image search on "terminal blocks". Almost any of the green ones from people like TE Connectivity have the screw push on a sheet metal pad.

Benta:
The other way is to use ferrules on the wires.

ajb:
"Rising cage" or "rising clamp" is a common term for one type of terminal block that has this feature.  "Wire protector" is another type.  I'm not sure what you mean by "chocolate block" terminal strip--it would probably be best if you showed a picture or part number so we know what you have in mind--but I've never seen either type of wire protection on either of the two items I imagine you might mean. 

If you can't find the type of terminal strip you want with those features then you should probably use wire ferrules.  If you are willing to switch to a different type of terminal solution, there are a ton of options in DIN-mount terminal blocks you might look at.

--- End quote ---

* Never tin wires, before putting them into a terminal block. It makes them more brittle and provides lubrication, making it easier for them to come out, once the solder has crept.
* Bootlace ferrules can be used to keep the wires from fraying.
* To stop the wires being damaged, don't overtighten. Gently tighten the screw, until the wire becomes held in place.
