How to make stronger electrical contact? - Honda Prelude Forum

SNsLude · 01-23-2006, 05:39 PM

In a former thread, my problem was that the contact the connections had on my icm were either loose or poor... anyway to make this connection stronger other than crimping them down? And I don't think theres any room to put copper strips or anything either. Any sprays or gellies you can use?

Heat shrinking is probably the best way to go.

Heat shrink will help prevent shorts, and silicone can be used to weather-seal them.

Solder would be best for mechanical and electrical reliability.

Also, clamp the cables down somehow, so you can't pull them loose or damage the connectors. Using cable-ties to attach them to something solid is usually sufficient.

dielectic grease... it won't help with conductivity, but it'll keep the connections clean...

mount it from 2 points?

hmmm... I don't see how I could solder it on to the ICM, unless you guys mean by cutting off the butts, splicing the wire, and solding the wire tips straight on to the contacts... the only options I see are adding some kind of gellies or clamping them down... The ICM has 4 metal connection prongs that stick out from it (like in the picture below) and the connections I'm talking about are supposed to slip over these metal prongs on the ICM (part #8):

And sorry, not sure what you mean about using cable ties? You mean like strap the connections down to act as a clamp?

appreciate the replies guys... ill try some silicon or dielectic grease as for starts... don't think it can help it stay on stronger though... I think thats the main problem...

When I first replaced my ICM a few months ago, the connections were stuck on there pretty good... after i replaced it and stuck the connections back on, they've lost its grip on it... it's easy to take off the connections... I tried clamping them down but didn't seem to work too well.. it was only a temporary remedy.

If you use OEM connectors there are a few things you can try. When I used to repair old copiers we always had issues with the connectors loosening and getting corroded. We would basically use a tiny flat-head screw driver and pick-hook to clean out and scrape along the inside of the connector pins and lightly file the flat surfaces. after that we would slightly bend the female clips so they would be tighter. The dialectic grease would help keep them from re-corroding.
I'm not entirely sure of the actual issues you are having, but hopefully that helps in general.

I see... thanks ^ ... Yah someone mentioned that soldering on the ICM will fry it... so that's out of the question. Basically picture a speaker with the positive and negative terminals that stick out... thats basically how it is with the ICM... and the connections slip right on over the terminals... but they are quite loose... I can jiggle it and they are quite easy to take off even after i tried to clamp them down quite hard.

.
.. so here are the terminals... they slip over those metal things the blue arrow is pointing too.. I tried clamping and it just doesnt do the trick..

solder it.
