Sockets to fit on CO2 tube terminals?

Sockets to power CO2 laser.

Does anyone know where to acquire suitable plugs to fit over the pin terminals of a CO2 laser tube? I'll attach picture, I'd prefer to do it properly instead of using alligator clips, a proper insulated socket to fit over the pin is needed but I'm not sure where to look.

Would it be possible to solder a small piece of wire to the pin and then stick a connector on the wire? I don't think theres any specific connector for CO2 electrode pins.

That way you can heatshrink it a couple times and have good HV insulation right at the tube.

just remember to use wires section and connector types that can hold the needed currents, not just the needed voltage insulation ;)

The currents are less than needed for most LEDs. What kind of wire can't carry 20mA reliably? It'd have to be 52 gauge or something!

Any connector you want to be perfectly safe to poke around would either need to be perfectly flush with the glass around the electrode or be several inches wide and wrap around everything in the area. And that's tricky to do. Often, the front end is grounded so you won't get zapped if you touch that side. Just stay away from the back of the tube and use alligator clips.

Another reason to stay away from center-tapped AC if you can.

Thanks fellas, after looking around the shed I found some connectors for crimping two wires together that could be made to slide over the pin, then use a skirt off a spark plug lead slid over the HV cable to insulate it.

Be careful your spark plug lead isn't the carbon type, they have a pretty high resistance and will limit your power.

No not the actual lead, only the rubber skirt that fits over the spark plug. It should fit well over the glass protrusion below the electrode.
