How to join a cable

[herald_400rl]

I'm not bad (or fantastic) with electrics, but struggling to find a fitment for this. Don't want to spend 40 quid on a new lead.

I've tried a little bullet thing but the bullet hole be too small.

What is the cable for? Is it 240V or 12V? What size current should it carry?

Personally my first choice is usually a choc-block: a plastic box with a metal tube through the middle, where the wires are connected by two screws. I would then cover it with insulation tape, especially if it is 240V or in a potentially damp situation.

I might be tempted to solder it, assuming I can find some way of holding the two ends in close contact (and I have access to tools and solder!). Again, insulate it.

Perhaps a Scotch-Lock connector, where you push the two leads in and then squeeze a connector to lock them in place.

It's the high voltage end from the fridges piezo igniter, so 10,000 volts+ at tiny amps. The pin in the white plug is held within, here is a picture of the 3rd dimension:

So I'm struggling to see what fits. I have a bodge idea which is to cut the plastic off and use a choc block.

This is what the cable end should look like, but it corroded off (black end):

If its to go in the white plastic hole you could try one of these.....dc jack plug.
You just need to know the diameter of the pin.
There are a number of sizes available.

You could try an insulated butt connector, in three sizes: red (small), blue (medium), yellow (large). I expect the red one would work best, but it's hard to judge.

If necessary you could trim back the plastic insulation if it doesn't fit in the hole. And maybe squash the metal circular part a bit so it grips the metal electrode. Crimp the wire into half of the connector.

When these components are designed and built there is a very good reason the cable, fittings and materials are very carefully specified, principally to stop you going up in flames (amongst many other reasons relating to standards). My advice is to install the correct components for the application and sleep well.

They are a pig to joint well. It's the same sort of thing used with old CRT TV''s. The joint insulation also needs to be up to the high voltage or it will jump to any nearby metal with a nice spark. Best replace the whole ignitor with cable.

Otherwise, you need to find something with crimp connections of the right size. That from experience is not easy and you need a proper ratchet crimping tool, and much more than LX PVC tape to insulate it. Heat shrink sleeving of appropriate size, perhaps two or three layers may well do the trick.

Sorry to bring bad news.

As previously quoted the high voltage used for the ignitor will "jump out or leak" at the slightest chance. In an emergency I would just push it in and support with heatshrink but the proper answer is a new crimped up lead suitable not only for high voltages but also to withstand the high temperatures around the burner. If you bodge it then it may melt later and could then damage the spark generator.

I'll tale a trip to our local caravan/motorhome goody shop in the morning and see whats cracking.
Appreciate the comments on safety.
