I need to connect 10 thin single-core wires to each other permanently. They will carry at most 1A at 5V in total (100mA each). Can I just solder them together in a lump with shrink wrap tubing around? Is there a better or more normal/professional way? The wago clips is useful for testing, but looks "temporary" and work-in-progress, so I'd like to remove them.

Sorry I don't know the wire gauges, but you'll get an idea from this picture.

    \$\begingroup\$ Why would you have such long wires in something permanent? What are they connected to? What kind of application is this? \$\endgroup\$ – Elliot Alderson Sep 20 '18 at 12:25

    \$\begingroup\$ Hi @ElliotAlderson! It's a little LED grid base for an art project with light-diffusing sculptures. Picture: photos.app.goo.gl/9wxAX6i8CqGRJ6F4A An obvious design mistake was to not connect the individual LED strips, both via power and data. I'm keeping the wires long to make it easier to handle, good idea to make them shorter. I'd be happy to have all my other design mistakes pointed out, as I'm pretty new to this. \$\endgroup\$ – Anna Sep 20 '18 at 12:31
  • \$\begingroup\$ I'd drill holes in the base at the end of each strip and take the wires down through them - then connect them together underneath and run a single pair to the supply. \$\endgroup\$ – Finbarr Sep 20 '18 at 12:37
  • \$\begingroup\$ @Finbarr Thank you, of course I should have thought of drilling holes. Great idea. How would you connect them underneath? All 10 wires joining in the center with a lump of solder and a supply wire? \$\endgroup\$ – Anna Sep 20 '18 at 12:43

    \$\begingroup\$ That would work, or you could run two lengths of heavy duty wire either side of the holes as busbars and join each strip to them. The main thing is to make sure the ground wires are all connected together and to the ground of whatever is driving the signal wires as well as possible. \$\endgroup\$ – Finbarr Sep 20 '18 at 12:47

You could use a piece of stripboard to solder the wires to, and some PCB screw terminal connectors for a neat, disconnectable connection to the power supply.

You might need to drill slightly larger holes for the PCB screw terminal connectors.

If you solder all the wires together in one lump, it will be difficult to remove one if a replacement is needed.

I know Digi-Key and I imagine other distributors sell these Butt splices. These ones cover 12-22 AWG and carry up to 24A. They have 2,3,4,5,or 6 position in this series. Might be an option for you situation.I know 3M has some as well that have a sealant in them. Just not sure if they have the same range and amp rating. https://www.digikey.com/short/jwrttp

  • \$\begingroup\$ Thanks for your answer. That's what I'm already using though (see text and picture), and I'm looking for a more professional-looking solution. \$\endgroup\$ – Anna Sep 20 '18 at 13:34
