Help identifying these cable lugs.

[Yamin]

Hi guys, I am in the middle of rewiring an espresso machine. I couldn't find the exact matching types for the following cable connectors. I couldn't find the proper names for these as well, maybe different manufacturers are using different names.
The dimension of this connector is 6.3mm x 2mm (front side) and 20mm long. Uninsulated, the cover also looks different from what I normally see and some of the connectors use a black cover.

Hope you could shed some light on it.  I'll include the other connectors in next post.

Thanks in advance.

Usual FASTON connectors.

Here are the other type of connectors, these are more generic type. However the insulation have a more glossy finish to it, wondering whether this is significant made up of more heat resistant material.
Also are these called spade connectors? I am looking for the uninsulated and insulated connectors.

Please advice on where to source these connectors as well.

Anywhere. Even small electronic component shop should have them in stock.

I also thought so too, but couldn't find this kind of locking type. Also if I search for 'spade' connectors similar type of connectors are shown

So these glossy insulation is not significant right, thought it might have been a special kind which might be heat resistant . Local shops carry similar types but the insulation looks more dull.

The local shops don't carry the type found in post#1 and also don't have the cover.

FASTON come in non-locking and locking types. Despite locking mechanism may be looking different from different suppliers, they are completely interchangeable. Also what looks as non locking, still has a bump for locking in place. It's just that in locking type you must release the lock before removal.

Those with insulation sleeve have different crimping type and thus need different crimping tool. You can replace with whatever crimping type you want. It does not affect anything.

As others said it's a faston...

I recently helped a friend of mine with the expresso machine repair.
Be aware that all the wires that are connected to or near to heat sources (heater), should be suitable for high temperatures and so the connectors. Do not use regular Cu-Sn fastons for the heater, they will burn out pretty soon...
We used a silicon insulated wire, rated for 180°C and Nickel coated steel fastons for connections. I got them from Farnell.

Whenever you meet a connection to the hot part of the heater, allways use appropiate high temp. cable lugs or fastons and use stainless steeel bolts/washers/nuts. Never use regular zinc plated nuts and/or Sn coated cable lugs!
