Hi sorry, not really speaker related but someone here might know. I repaired my oven in November and replaced some damaged connectors with these https://www.ebay.co.uk/itm/222642667025 had the oven on for several hours yesterday and it tripped the circut breaker. Just taken the back off and the connectors have melted together and shorted. Looks like from heat rather than from over-current. They are situated very close to the back of the oven compartment and I will check the oven for leaks. and I can relocate the connectors slightly and put in some additional heat shielding. But can anyone suggest some more heat resistant connectors? The melted ones say they are polyamide. I've tried searching for 'high temp' and 'heat resistant' but not finding anything.

Polyamide's glass transition temperature, at which it will start to soften, is just 50-70C - so those are not high temperature connectors at all!
Try ceramic screw terminal blocks, such as are found in the backs of tungsten parcans. The GTT on those is about 1200C ;)

Or cover everything with heavy duty heat-shrink? |

TBH I don't think polyofin (yep that is spelt WELL wrong) sleeve is the way to go here, i would just get non-insulated butt crimps and cover the whole lot with systoflex style "Silicone Coated Braided Glass Fibre Sleeving" which will one work and two give you more time to cook stuff like this :- |
