 Posted: Thu Jul 08, 2010 1:09 pm Post subject: Quick splice connectors? |
 |
|
I've begun wiring, and have always hated cutting a good wire
to splice into it. I've found no reference to the quick
splices in any of the aircraft parts catalogs, so before
giving up, and cutting the ignition CDI wires to connect
the kill switches (That alone feels all sorts of wrong to me..),
I thought I'd ask the question: Has anyone used a splice
such as http://www.wiringproducts.com/contents/en-us/d266.html
in their wiring?
Thanks,

Keep in mind that the design goal for bringing
two wires together is "gas tightness". I.e.
give the joining the same environmental resistance
to effects of moisture and oxygen as if they were one
piece of metal. Detailed discussions of these goals
and some of the recipes for achieving them are
discussed at:
http://aeroelectric.com/articles/rules/review.html
http://aeroelectric.com/articles/Solder_Lap_Splicing/Solder_Lap_Splices.html
http://aeroelectric.com/articles/terminal.pdf
The splices you've cited are not crafted to
these design goals. I've seen those used on aircraft
that traveled to various air shows . . . but
the question to be asked is not "have you used
them?" but "what studies have shown them to be
of the same caliber as legacy products and
processes that have been proven to be essentially
zero risk?"

Jack;
Absolutely not!
These were developed, I believe, as a "quick'n'dirty", temporary connection
in the automotive industry for such applications as a one time trailer
hook-up for say a rental trailer. Personal (bad) experience is that they are
unreliable and in a very short time the nice one piece original wire will
corrode through where this so called "splice" damaged the insulation. I
wouldn't use them for anything let alone on an aircraft.
They certainly don't provide the nice solid "gas tight" joint that the
properly crimped PIDG terminals provide. Where and how would you propose to
use such a connection?
I don't follow the reference to having to cut the CDI wires. The power
supply to a CDI ignition, I would have thought, would involve a supply wire
and a ground wire just like any other accessory. No?? If they need to be
"spliced" then a proper PIDG splice is the way to go. See
http://tinyurl.com/2575j6g or http://tinyurl.com/27zackn
Now all of this is my personal opinion and others may differ, but for what
it may be worth, there you have it.

Jack,
I was going to respond to your question regarding the splices you asked about, but then I read Bob McC's email. He said essentially the same thing I was going top say. These splices are what the (U-Haul, Ryder, etc) trailer hook-up guys grab, to keep from doing a proper splicing job. They're quick, they corrode, and they're virtually useless on anything of long term dependability.
I've used them, but NEVER on an airplane. Basically, they're junk. My opinion....

That whole concept of gas tightness is what led me down the
path of those connectors: I figured leaving the wire intact
in the first place was better than cutting, then rejoining
the wire. I'd looked at the mechanical support from the
better connectors, and didn't see any disadvantage there,
but had not considered the galvanic reaction from
dissimilar metals. That might be a problem in an amphibian.
The entire plan was to follow the whole theory of the kill switch
in the first place- if it fails, the engine keeps running.
I'll go down a modified solder-lap approach. I'm *much*
more comfortable with solder joints than crimp joints,
and will support them with a double heat-shrink cover.
(Lead exposure? What might a few years of soldering circuit
boards by hand add in the way of exposure? I figure that's
why I'm always on a diet..)
Thanks again,
Jack

Jack :
They use those splices at the U-haul trailer place. They will screw
up your trailer wiring in about one year they are junk. I would never
put anything like that in my plane. I would trim the insulator back
real careful and solder the wire you want to connect then use some of
that plastic stuff coat in and cover it with shrink wrap. STeve Not a

The "exposure" is nil. There are some folks
who believe that the mere proximity of a toxin
opens a channel of ethereal osmosis that drives
up risk. It's healthy for them not to study
potential toxicity of every substance in our
daily lives . . . the American Psychological
Association would have to name a new phobia . . .
or perhaps they already have.
I've been soldering various items together
for over 50 years. I have a lifetime stock
of 63/37 solder in many forms and intend to
use it until the lead finally kills me . . .
or my heart does. My money is not on the lead.
