Hi all,
I have recently converted more or less completely to Anderson Power Poles for all my power supply needs. I use an 8-way "hub" from Powerwerx as my "distribution center". No fuses as the switching power supplies are current limited and probably failsafe in the event of most electrical component failures. For the big stuff, radios with #12 power wires I am not worried about the lack of strain relief on the connectors. But for the flimsy power cables supplied with accessories like my KAT500, LP-100A, Lantronix serial servers I am. Has anybody found a good solution for this? Should I just fill the back of the connectors with epoxy or is there a better way? Knut - AB2TC |

Knut,
If you are referring to the flexing of the wire out the back of the APP connector, that is a valid concern if you move things around frequently. Actually, I have had no problems even with #18 wire. Stay away from the epoxy unless you want it to flow onto the contact area and render the connector useless - Hot Melt glue would be a better solution because it does not flow easily. I would suggest a few layers of heat shrink on the wire with a last large diameter heat shrink pushed over the back of the APP connector. If you have no fuses in that distribution box, I would highly recommend inserting in-line fuses in the smaller gauge wires. You are not protecting the equipment, but you are protecting the wire in the event of a fault. If the wire cannot carry the full current of your supply for a substantial time, then fuse it. I fuse #16 and #18 wire at 10 amps. #12 and #14 wire will likely be OK with a power source of 35 amps or less, but I would recommend fuses on any larger supply, and definitely fuse any battery, they can let out a LOT of current. Safety first and you can keep hamming for a long time. 73, Don W3FPR On 4/24/2013 5:20 PM, ab2tc wrote: > Hi all, > > I have recently converted more or less completely to Anderson Power Poles > for all my power supply needs.

Hi Bill: I've found that if you strip the wire twice as long as necessary
and then turn it back on itself to the proper length, the crimp has more to grab hold of and it will not pull out - I'm using a regular Power Pole crimper. 73, Doug VE3MV ----- Original Message ----- From: "Bill Frantz" <[hidden email]> To: <[hidden email]> Sent: Wednesday, April 24, 2013 6:33 PM Subject: Re: [Elecraft] OT: APP strain relief > On 4/24/13 at 2:20 PM, [hidden email] (ab2tc) wrote: > >>I have recently converted more or less completely to Anderson Power Poles >>for all my power supply needs. ...

A good idea. I'll try it the next time I have to make up some
small wire APPs. BTW, I solder the connections before I put the contacts in the shells.

If you solder smaller cables you need strain relief even more. The solder
makes the wire stiffer as it wicks up the wire,making them more prone to breaking in my experience. The heat shrink also makes them a little easier to insert into the housing. Two layers of the thin stuff or one of the heavier gauge. On Wed, Apr 24, 2013 at 9:11 PM, Bill Frantz <[hidden email]> wrote: > A good idea.

I just placed an order with Powerwerx for a special 45A pc-mount
connector and special #10wire plug to use 10awg wiring with my amplifiers. The 300w amp runs 17A at 27vdc so the heavier dc wiring will be useful (typical 60% effficiency). I am building a CCI AN762 (5w/140w) amplifier kit and will use the same dc connector. Estimate it will draw 234w dc load at 13.8v which is 16.9A. I plan to bring the amp to Dayton to show and sell. I am just finishing winding the cores for the six band LP filter. Testing next. 73, Ed - KL7UW ______________________________________________________________ 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 |

For the fine wires, before crimping I slide a short length about half
to 3/4 inch length of shrink tubing with a diameter just big enough to fit over the crimped end on each lead then I slide another piece of shrink tubing over both wires about 2 inches long and slide it out of the way for now. once the crimp and soldering is done I slide the short tubing so that it is just covering the crimp then shrink it then I slide the terminals into the connector body and join the two together and line them up. Then I slide the longer shrink that covers both wires as close to the APPs as I can and shrink it. It makes a tidy strain relief As a side note I never use the pins to hold the connector pairs together I find that they can still come apart Crazy glue does a much better and more permanent job. 73 Dave VE3DVY .

{Directed at no one in particular. Don't take it personally, anyone}
I think someone already mentioned doubling the stripped wire back over the insulation, then putting that in the APP terminal. I'm pretty sure that's what Anderson recommends. But then you have to PROPERLY crimp it, not solder it. Do that and you won't need strain relief in ordinary service. So treat yourself. West Mountain has an EXCELLENT crimper good for all three APP terminals, and as quality crimpers go, it's dirt cheap...$40...the price of two large pizzas. Anderson has one too, but you need a credit check to buy it. I've done hundreds of crimps with the West Mtn crimper for ham, auto and R/C use. Soldering APPs is ridiculous and produces an inferior connection that NEEDS strain relief. You select a stranded wire, then wick solder up it to make it a solid wire. That's nuts. I've heard from lots of R/C people that crimping makes an inferior connection and the connection should be soldered as well. Tell that to Mercedes or any quality auto or motorcycle manufacturer. Except for PC boards, just try to find a soldered joint in an automobile of any quality. You won't. Everything is crimped. I don't know for sure, but I'd bet all aircraft connectors are crimped. I bet the SR-71 connectors are all crimped. Probably the Shuttle too. Shouldn't that be good enough for a 12 volt ham rig? Crimping isn't inferior. Crimping with crap tools is inferior. Well, that feels better.

you are correct that a properly crimped connection is as good as
soldering but that really wasn't the point and I'm not sure why I even mentioned soldering perhaps because I know that some do. I just crimp as its way faster less burns and swearing and works fine for me. The biggest downfall of soldering APP is that the solder and flux can run down the pin where contact is made defeating the silver plating creating problems. However, whether you crimp or not, with light gauge wires like that the power cable for an HT or small accessory, a strain relief will help prevent wires from breaking off right at the end of the connector due to fatigue. Frequent connecting and reconnecting plus moving equipment while connected will break the wire right where it comes out of the crimped connector pin. (I'm not talking about the wires pulling out). A strain relief will reduce the radius of the bend in the wire at the connection when it is moved around I don't see how crimping the connector alone will prevent a wire bending and eventually breaking off from fatigue As for Mercedes Way back I was a Mechanic at a Mercedes dealer and I know for sure that Mercedes Benz soldered plenty including pins for the connectors. I'm sure that is changed in the last 3 decades due to manufacturing cost. David Moes [hidden email] VE3DVY On 5/2/2013 21:42, EricJ wrote: > {Directed at no one in particular.

Well, we might be talking past one another to some extent, because we
seem to be largely in agreement. When I suggested folding the stripped wire back over the insulation for fine wires, that takes are of the fatiguing problem without strain relief because now you don't have bare wire at the end of the terminal. The insulation runs all the way inside the barrel. I've never had a failure using that method for small and fine wires. In R/C, we are often pulling connections apart several times during every flight day and more times on the bench. Nothing in a ham shack gets that kind of flexing. Never had a crimped connection fail, but I used to have lots of fatigued solder joints in R/C.
