Push on Crimp Connectors

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am looking for push on 'female spade' crimp connectors that are 4.8mm wide and suitable for 4mm cable. 
I have some of the yellow 6.3mm type suitable for 4mm cable but the extra spade width means they can't be used on 8 pole speakon connectors.I also have some blue 4.8mm connectors that fit on the 8 poles, but only accept 2.5mm cable.

Does what I am looking for exist? I am not having much luck finding something suitable.

Cheers

	Solder them on mate, much better contact and will give you the peace of mind knowing they are never going to come loose..

	I don't think they actually exist. Probably because 4.8mm tabs aren't rated for high enough current for bigger than 2.5mm cable to be necessary.

	+1 for soldering them on, they stay on really well and you can easily heat them up and slide them off again at a later date if you ever need to.

	I crimp and solder the cable into the connector then solder the connector to the tab with a bit of hot glue over the top. Never had one come loose. I can't see how soldering 4mm cable onto 8 4.8mm tabs is going to be as secure... The spade connectors act as a handy way of holding the cable in place whilst you solder. You are right about that ceharden. I think the 4.8mm tabs are only rated to around 16amp. I might just stick to 2.5mm. The run is only a foot or so.

	Yellow 4.8's dont exist .. however, you can buy neutrik sockets with 6.3mm terminals, they are the higher 40a rating NL4MP-UC , personaly i wouldnt solder 4mm to terminals as you could run the risk of melting the terminal .. my patch cables are 6mm , crimped then soldered to the socket, best of both worlds then ... and dont use a cheap crimping tool, you get what you pay for, the same with crimps the goods ones always have a secondary metal liner

	Thanks Johnny, that's why I couldn't find yellow 4.8s then! I didn't think about checking for speakon connectors with wider tabs . That's seems the best option as I have 100's of yellow 6.3s

	No worries mate .. oh and if the yellow 6.3's arent insulated spades, then just use some heat shrink and if you can solder the 2 terminals together. thats a bonus, less chance of it ever coming off

	Yeah, I prefer the non-insulated spades so I can solder the terminals together. The 0.5mm thick spades are tough to remove as it is, so soldering them together should mean they never come apart. Well, I've never had one come apart before at least!

	Yeah me too ... i used to install a lot of power and nav systems on boats and i much preffer a crimp then soldered .. probably over kill, but i think i would do my nut if i just soldered it and for some reason it came off and shorted out .. i wouldnt be best pleased to burn out a channel on an MC2 amp , just for the sake of a few pence lol

	You're right about melting the plastic. To heat up a 4mm cable to the temperate required for a decent solder joint takes a long time and causes havoc to both the cable jacket and speakon chassis. Maybe we need a 'Show off your neatly crimped & soldered 4/8 pole speakon chassis' thread.

	on the same subject ive just gone and bought some blue female 6.3mm crimps from screwfix to wire up my speakon plugs in my patch pannel and back plates. i have 2 questions, 1. the crimps are all very close on the speakon plug and im worried about shorting them out on each other. whats best to avoid this? heatshrink? 2. just had a word with a mate about this (i was so proud of my neat back plates i sent him a picture) and he tells me that the crimp joint will change the resistance load on my amp?!?!?!? and that best practice would be soulder only joints. Is this true? im sh*t at souldering for a start so crimping is great for me.
