A trivial question on vivi nova (or similar clearomizer) coil head, trying to build my own coil...

[paulw2014]

Hi, I'm interested in making my own coil for the vivi nova. The way the head is designed, you have the heating element coiling around the wick and then connecting to the positive and negative terminals at the bottom of the head, separated by a silicone/rubber like insulating cap.

The heating element seem to be touching the rubber insulator cap, so how come it doesn't melt it? I understand that silicone can withstand heat well, but I don't think it can withstand direct contact with a heating element wire.

But then again, maybe the heating element is not hot in that section? Every time I do a dry burn, it seems only the coil section glow, the part of the heating element that goes down to the terminals doesn't seem to glow (can't see it that well).

Just curious, please advise, thanks

In general, the silicone plug is heat resistant enough not not be a problem. It can, however, over time and high current, start to scorch.

Some makers use a "no resistance" lead on both ends of the coil, and it's possible with the right equipment and skills to do the same, but lots more work and generally, imo, not worth the effort. (All electrical conductors have some resistance.)

If, over time, the scorch tracking becomes an issue, just get a new head.
