About this part
Worth understanding how the clamp works before buying any solderless plug, because it decides whether the joint lasts. Unscrew the cover and the body is hollow at the back with a hole drilled across it. The conductor goes in from the rear, and as the cover threads down it squeezes the copper against the inside of the barrel and against that cross hole. Nothing melts and nothing gets hot. Strip about six or seven millimetres, twist the strands, push until the wire stops, then tighten by hand until it will not turn.
The failure people hit is stripping too much. Bare copper left proud of the barrel sits under the skirt of the cover where it can touch whatever the plug is pushed against, and a strand that escapes the clamp becomes a whisker. Strip short, and if the wire pulls out under a light tug, take it apart and start again rather than tightening harder, since over tightening spreads the clamp and the part never grips properly afterwards.
Five of these are on the shelf in a medium blue cover. The metal carries no maker's mark and the plastic is moulded plain, so this listing describes the pattern and the measurements rather than guessing at a factory. It matches the white plug in this drawer in every dimension.
Questions about this part
How much insulation should I strip?
About six or seven millimetres, enough to fill the barrel and no more. Bare copper proud of the barrel sits under the skirt of the cover where it can short against whatever the plug touches. If in doubt strip short and check the fit before you tighten.
Why does this listing not name a manufacturer?
Because the part is not marked. The metal is too small to carry a stamp and the nylon was moulded plain, and the bag arrived without paperwork. It matches the pattern of the documented Johnson plug in this drawer in every dimension, but a part number in a title that nobody can verify is worse than an honest gap, because somebody orders against it.
What if the wire pulls out?
Take it apart and start again rather than tightening harder. Over tightening spreads the clamp permanently and the plug will never grip properly afterwards. Usually the cause is too much strip length, so the clamp is closing on insulation instead of copper.
Can I solder the wire in as well?
You can, and people do for a permanent lead, but it defeats the point. The clamp exists so the plug can be recovered and moved to another lead later. If you solder it, keep the iron off the nylon cover.
Only five are listed. Can I get more?
Ask. Five is a hand count of what is in the bin, not an estimate. The blue ones were the smallest group of the three colours that came in together, so a larger run may not exist here, but it is worth asking before you design around it.
