When building Go Boxes, I used to find connecting together the power distribution cables for the equipment a hassle, until I found these Wago connectors in an electrical distributor. They are widely used in the UK for house lighting wires and come in 2,3 and 5 conductor capacity.
As they are quite small, I bought a box of 5 conductor units with the view that even if I only need 2 or 3 for some applications, they don’t use up much space, and if I need more connections than I thought, they are available.
The connectors are rated at 32 Amps and capable of taking up to 4mm square cable, you just lift the lever and slide in a stripped cable, then push it down for a secure connection. Use one for +ve and another for -ve & job done. A decent length of the insulation slides into the connector so shorting to the metal panel below is not an issue.
The main picture shows a project I’m just getting started on with the first wires connected, and the pic below gives the part details.
I also use a lot of this Acrylic foam tape which is very sticky, holds well and doesn’t lose its grip with time. While described as foam, the material is more a clear plastic somewhat stretchy gel, a couple of mm thick with adhesive either side. This helps if the surfaces are not completely smooth/parallel.
Its perfect for sticking these Wago connectors down, and for mounting other lightweight parts.
