Anderson Connector
Locked
 
|
Hi
Just finished building the basic K3 (sub rx and 100w PA awaiting installation). Total build time was about 10 leisurely hours spread over a week. Throughout the entire build I have only found one small issue which I find remarkable! Hats off to Elecraft. Anyway, my issue is the Anderson power connector doesn't firmly latch onto the connector on the rig. It fits on and powers the rig but pulls off very easily. Have I installed it incorrectly maybe? Tnx Jack -- 73 de G8DX/P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Jack,
The most common cause for that condition is that the connector blades have not been inserted into the APP body far enough. Look at the end of the connector assembly - if you can see the tip of the spring finger under the contact blade, then the blade has not been fully seated - give it a push with a small screwdriver and it should snap into place. A properly constructed APP connector takes about 10 pounds of force to remove it. 73, Don W3FPR On 6/24/2013 8:26 AM, G8DX wrote: > Hi > > Just finished building the basic K3 (sub rx and 100w PA awaiting installation). > > Total build time was about 10 leisurely hours spread over a week.

Thanks for all replies both on and off list.
I will take a look tomorrow and see if I can improve it. -- 73 de G8DX/A On 24 Jun 2013, at 13:42, Don Wilhelm <[hidden email]> wrote: > Jack, > > The most common cause for that condition is that the connector blades have not been inserted into the APP body far enough. > Look at the end of the connector assembly - if you can see the tip of the spring finger under the contact blade, then the blade has not been fully seated - give it a push with a small screwdriver and it should snap into place. > > A properly constructed APP connector takes about 10 pounds of force to remove it. > > 73, > Don W3FPR > > On 6/24/2013 8:26 AM, G8DX wrote: >> Hi >> >> Just finished building the basic K3 (sub rx and 100w PA awaiting installation). >> >> Total build time was about 10 leisurely hours spread over a week.

10 Lbs? Ive used APP for years and I am quite satisfied the whole shack
is done that way. however Ive never had one set strong enough that I think could dangle the weight of the K3 let alone a full 10lbs what am I doing wrong?

According to:
http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/15-amp-red-black-anderson-powerpole-sets.html "When two pairs are mated together, it takes approximately 3 pounds of tension to pull them apart."

Nothing! There is nothing to keep these connectors mated but a small amount of
friction. 73, Roger On 6/26/2013 8:08 AM, david Moes wrote: > 10 Lbs?

I believe Don was saying that it takes about 10lbs of force to properly seat the APP contact into the housing. It takes more force to seat the contact in the housing than to pull the mated contact apart. If it didn't work like that the connector would fall apart when you disconnect it.

However, if your making your own connectors up, you can get latched covers.

Viewing the connector cutaway picuture, just above the section
"Stainless steel spring" in the page: http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/15-amp-red-black-anderson-powerpole-sets.html note that the connector is locked-in between the spring and housing. As noted before on the list, a common assembly error is not inserting the pin far enough to lock-in between the spring and housing. Or a crimp has warped the pin such that a spring to housing lock can not be established. Also note in the picture, the mating connector pin bends, which lock the mating connectors together. The matting lock will not be established if the pins are not fully inserted. If the connectors pull apart without a little catch, then check for improper pin insertion.

Friction does a pretty good job keeping a Formula One car on the track at 150mph or bringing 115 tonnes of Boeing 747 to a standstill on landing. And adding that little spring makes a Power Pole even better. Seriously, if your Power Poles come apart when they shouldn't, you are doing something wrong.

The spec sheet for the Anderson PowerPole Family shows an average 2-5
lbf for mating/unmating force for a single connector. But frankly, I didn't understand their use of the terms High Force and Low Force wire/PCB. Nevertheless, a pair should be 4-10 lbf. http://www.andersonpower.com/literature/datasheets.html I measured a dozen of the APP pairs in my shack and came up with 64 ozf average for a pair using a fish scale. The highest was 66, the lowest was 60 oz. That's an average of 4 lbf for a pair so it's in the ballpark of expectations. I don't have a problem with accidental separation, but sometimes the wire clutter behind the rigs gets a little dense with time and if I have to pull a rig out, my fumbling behind the rig can dislodge something. I set up all my non-APP rigs with a small dongle about 3 inches long that terminates in a an APP pair at one end and whatever the rig needs at the other. Then I made up two sizes of extensions with APP pairs on both ends. So every piece of 12 volt equipment in the shack terminates in an APP dongle that can plug into my standard APP extensions to reach the two RigRunners at the rear edge of the operating desk. No more accidental disconnects except right at the non-APP rigs where the radial power connectors are. Those I can easily find and reconnect if they happen. Some day I'm going to get brave enough to convert the K1 and K2s to panel mounted APPs like the KPA100 but that day isn't here yet. The only time I've had problems with APPs is with really thick wire. What happens is moving the rig against two thick wires puts lateral forces on the APP pair and it eventually wiggles free. The answer is to properly size the wire for the rig. You don't need 75 amp connectors on a K2/100 or K3/100. Eric KE6US On 6/26/2013 5:08 AM, david Moes wrote: > 10 Lbs?

The APP spec sheet provides mating/unmating force as 2-5 lbf. It's the same.
http://www.andersonpower.com/literature/datasheets.html I think what Don was referring to is that a PAIR of APPs--the way we typically use them--can take up to 10 lbf to unmate (or mate) which is consistent with the spec sheet, though at the high end.

Thanks for the test Ron,
that sounds about right when I pull them apart. BTW, I never put a locking device on to hold them together either. Sometimes when I take my mobile radio out of the car, or moving it when operating portable, I forget to unplug the powerpole connector and when pulling the radio out the power pole disengages nicely without me jerking on the power cord and possibly damaging something.

I have had no difficulty with APPs pulling out . I have had trouble with the dc co-axial/barrel connectors used for low current use, like the KAT500. That one has pulled out a couple times while I've been rummaging about behind my station... And the little black connector is perfectly camoflaged so I can't find it...
