Deang Posted February 25, 2018 Share Posted February 25, 2018 And to stabilize the mechanical connection. You want a solid mechanical connection, with contact surfaces maximized - and then the solder, which will displace any air. A good crimp is as good or better than solder, but a “good crimp” needs to be gasless, and the crimper and disconnects are made to work together. I’ve seen too many connections with little contact between the leads, where the solder is primarily being used as the conduit for signal transfer. I won’t name any names. If the mechanical connection is good, and doesn’t move, and there is little or no air between the connected parts - you’re good to go - at least - that has always been my understanding. 1 Quote Link to comment Share on other sites More sharing options...

Deang Posted February 26, 2018 Share Posted February 26, 2018 I think you're right, I need to quit using that verbiage. Better to say it just locks out air and moisture, which causes corrosion. Quote Link to comment Share on other sites More sharing options...
Alexander Posted February 28, 2018 Author Share Posted February 28, 2018 I found these in the grommet section at Lowe's. They come both white or black and in this case they snap in perfectly. All we need to do now is drill the hole in the center and add a SS screw. Quote Link to comment Share on other sites More sharing options...

Alexander Posted March 3, 2018 Author Share Posted March 3, 2018 Would this be considered an acceptable way of making a connection? Quote Link to comment Share on other sites More sharing options...
babadono Posted March 3, 2018 Share Posted March 3, 2018 If the copper foil is bare at the point of connection I would think so. You are just going to put a hole in the foil, secure terminal with screw and lock washer and then solder to terminal? Quote Link to comment Share on other sites More sharing options...

Yes, put a hole in the bare foil, but not sure I have enough heat in my iron to try to solider the foil to the terminal though. I would be afraid of having to hold the iron on to long ending up hurting something even with a heat sink. Quote Link to comment Share on other sites More sharing options...
Deang Posted March 4, 2018 Share Posted March 4, 2018 Scuff the area where you are going put the hole (both sides). Once you remove the polypropylene coating on the copper, it heats very fast. I’m surprised ERSE didn’t tin those ends. Quote Link to comment Share on other sites More sharing options...

Ok thanks, and yes you are right ERSE did not tin the leads and did not think of there still being a coating on the leads. Quote Link to comment Share on other sites More sharing options...

I understood what you meant, I guess the price reflects on not tinning the leads - you get what you pay for so they say Quote Link to comment Share on other sites More sharing options...

Of course a soldered connection would be best but there are lots of electrical connections around this world that are mechanical only. Like the bond connection of ground to neutral in every house in the USA. Or the connection of the chassis in almost every stereo component etc...etc....
