Alan most Molex connectors are designed for price. They are ok for 15 to 25 
in/and out connections. You need a mil spec connector to hack the job long 
term. No connector lasts forever unless you never touch them. Let me put it 
more accurately, if you pay less than ten bucks for the connector, plan on 
replacing it in the long haul. Connectors and sockets are a large part of 
the cost of any manufactured project

1) Anderson PowerPoles can be configured to be gendered, though the

2) I have used the Molex since Heathkit days. Lots of them. They are
just plain unreliable in the longer term.

3) PowerPoles can easily be locked together when desired, but having
them pop apart easily is often preferred. It is up to the user this
way.

4) PowerPoles are not ideal, but they are the best thing going at this
time in the cost and performance category.

Show us better alternatives.. 12V 30A rated, low cost, low loss,
polarity protected, physically small, cable and chassis mount, readily
available, rated for lots of connect/disconnect cycles, easy to
install and plug/unplug.

De facto was a variety of connectors (2 pin Molex, T-connectors, others) 
on the power cables, all of which had "pigtails" of about 6 inches and

Re: [Elecraft] Alternatives to PowerPoles?

2008-04-07 Thread Sandy
Some time ago, I had standardized on the standard size 4 pin flat Molex 
connector.  On low drain (less than 10 amps peak) I just used two pins, 1 
and 4.  For high drain 100 watt rigs, I used all 4 pins, 1,2 in parallel, 3 
and 4 in parallel.  This worked fairly well and everything I had used these. 
The Anderson connectors seemed much more compact and I have had no troubles 
except trying to mate Tyco "AMP" copies with the APP connectors.  I found 
the Tyco stuff's quality was very poor compared with Anderson.  I have had 
NO troubles with the roll-pins keeping the connectors from sliding apart.  I 
usually crimp mine using a "universal" AMP hand tool I've had for years. 
You have to be careful after crimping and pay attention that the tongue of 
the connector isn't bent up or down too much to allow the spring in the body 
of the connector to function properly.


I've converted everything to them and they have worked well for me.

73 to all,

Sandy W5TVW

Re: [Elecraft] Alternatives to PowerPoles?

2008-04-07 Thread T. David Yarnes
I'm struggling a bit to understand your preference to the 
Molex connectors.  I find them troublesome from the 
standpoint of making your own connectors as opposed to the 
APP's.  By the way, I think the "standard" Molex seems to be 
the 6 pin rather than the 4 pin--at least of late.  My Icom 
and Kenwood rigs use the 6 pin, and the same pinout pattern. 
The Molex connectors are nice in that they are gendered, and 
they lock.  I certainly like that.  But I question that they 
are more durable.  I just stepped on an APP (with my 200 
plus pounds), and nothing happened--it's still fine.


My biggest concern with APP's is that they don't lock 
together.  It hasn't been a problem, but it just seems it 
could be.  They do make some plastic accessory clamps to 
hold two connections together--guess I should try those.


But for me, it's all about how easy it is to put together a 
connection, and the APP's seem the easiest right now by far. 
However, I crimp, which you (and several others) don't like. 
But I concluded from the arguments back and forth about 
soldering vs. crimping that soldering was just fine for most 
uses since we aren't using them in high stress situations 
more often than not.  But I did not conclude that soldering 
was better!  It was just that most seemed to feel it was 
only important if you were dealing with issues like jet 
plane vibrations, etc.  I'll certainly buy that.  But I 
think you still have to draw the ultimate conclusion from 
that argument that crimping is better, but not necessary! 
Maybe most would agree with that, and I would too.


So, I would conclude that the popularity of APP's is 
substantially because they are fast and easy, yet effective. 
They are fastest if you crimp.  It would be nice, however, 
if they locked together, and maybe it would be better if 
they were gendered.  Also, many folks want to standardize 
their connections.  That too is more easily done using 
APP's.


APP's are not the ultimate answer--not by a long shot.  But 
they do serve a good purpose for many.  If that wasn't true, 
people wouldn't be using them so much.  If you don't like 
them, don't use them.  If you don't like the fact that the 
K3 has them, make a pigtail adapter, and then use what you 
want.  That's certainly easy enough to do.

The major 13vdc ham radio equipment input power connector is 
the 4 pin Molex.  This connector has proven in thousands of 
uses to be adequate to the voltage, the current, and the 
physical demands of this utilization.  It is the de facto 
standard on K, I, and Y radios (for the vast majority) and 
the single only connector (other than the PL259-SO etc) that 
all three mfgs. amazingly agree on, making at least this 
matter so much easier for hams with different equipment 
mfgs.The four pins are often all used to increase the power 
handling capacity of the two-wire application.  However, 
theMolex in all its pin configurations has a number of 
drawbacks -one time installation (unless the use of a 
special tool to retract the installed pins is used), i.e., 
not reusable,-lack of strain relief.-lack of positive 
attachment fixture (i.e., it could be accidentaly pulled out 
rather easily).Good points are resistance to crush (step 
on), can stand multiple plug in and out, is very well keyed 
and can take solder with care.  It is reasonably available, 
but not in India, for example.  It does not need glue. 
Formerly, some mfgs. used a two pin mic connector which 
likely had the power handling ok, took soldering well altho 
the pins are close together, and had both a great positive 
attachment (screw on) and a fairly good strain relief. 
Drawback was possible confusion of thisconnector with a 
mic.The Cinch Jones is a good alternative because it comes 
in many pin configurations, including two, is very well 
keyed, takes soldering very well, has a good strain relief, 
is vy reusable, is medium resistant to crush, can be pulled 
out too easily, is widely available (altho its uses are 
dropping, restricting its availability), The size of the 
two-pin version is nearly the same as the 4 pin Molex.  The 
A Power Poles are the weakest of this line up of connectors 
and a very strange choice for ham radio applications.Charles

Convenience and flexibility.


That's a non-response, since it implies that alternatives aren't. I 
believe that most hams find UHF and BNC connectors to be convenient and 
flexible, and they're gendered. Given all the argument around crimp vs. 
solder on powerpoles, I might grant you flexibility, but not 
convenience :-)


 As radio amateurs, I'd hope we'd know a little about what we are 
doing.


That's a very poor assumption, given the types of questions I've heard 
asked by licensees.


We use the same RF connectors (although gendered) for everything from 
the legal limit of power down to receiver inputs; make a mistake and 
the results can be very unpleasant. Is 12 volts somehow more dangerous?


You've apparently never seen the results of a lithium battery 
explosion/fire. It's more than "unpleasant."


The problem is that with adapters it's just as easy to make such 
mistakes.


No, and saying that doesn't make it true. It should be obviously clear 
that a system which allows anything to plug into anything else is also 
the easiest one to make a mistake with.



There's also the advantage of a universal standard


It's not a universal standard. At best, it's a standard for one group 
in one country within ham radio (ARES/RACES). It's not used by the big 
3, and given the number of questions here from people who are new to 
the connectors, it's quite far from a standard in the general ham 
community.
