This was in the April 2009 of the Yankee Clipper Contest Club Scuttlebutt, evidently from Tom, N1MM.
Well worth reading for a better understanding of the "How to" of APPs. Too, a cheap but effective looking tool from Harbor Freight is noted. http://www.wakeares.org/powerpole/index2.html 73, Julius

I have a problem with APPs staying mated (specifically in my vehicle).
I've always wondered why there isn't some sort of positive latch. 73 de Terry KK6T Elecraft K3/100 #????

Gentlemen,
I would be very cautious of a crimp made with a tool that looks like that Harbor Freight model. It appears to produce a 'point contact' type crimp rather than a crimp over a large surface. Crimps of that nature can lead to high resistance contacts (and resulting heating and even fire hazard) due to the small area of copper that is crimped. If one should use a tool like that, crimp lightly to hold the wire and then solder well to assure a good connection. 73, Don W3FPR Julius Fazekas n2wn wrote: > This was in the April 2009 of the Yankee Clipper Contest Club Scuttlebutt, > evidently from Tom, N1MM. > > Well worth reading for a better understanding of the "How to" of APPs. > > Too, a cheap but effective looking tool from Harbor Freight is noted. > > http://www.wakeares.org/powerpole/index2.html > > 73, > Julius > > 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 |

Quicksilver Radio (qsradio.com) -- and probably others -- has 4 and 8
pole latching housings for APP's. Also Anderson has a PP75 locking Powerpole -- spring clip, won't just pull apart. Won't help with a typical (a la K3) chassis mount APP, but great for mid-span connections.

Terry,
Properly assembled 30 Amp power pole connectors require 6 pounds of pull to disengage/engage. If your are not staying mated, I would suggest that you look for a source of pulling on the wires and/or be certain your APPs are properly assembled. If you used a crimping tool that distorts the tabs, that alone could be the reason for a loose connector. I suggest you use a proper crimp tool, or solder the connections (without getting solder on the outside of the barrel). If you are using soldered connections in a high vibration environment such as a vehicle, be certain to reinforce the wire for about 2 inches away from the connector (2 layers of heat shrink) to keep the wire from flexing - constant flexing will cause the wire to break right where the point that the solder has wicked to. 73, Don W3FPR Terry wrote: > I have a problem with APPs staying mated (specifically in my vehicle). > I've always wondered why there isn't some sort of positive latch. > > 73 de Terry KK6T > > Elecraft K3/100 #????

I bought the ratcheting crimper from Powerwerx, slightly cheaper than West

> cheaper than West > Mountain Radio and no worry about bad crimps. I just replaced the Power Poles that I had messed up on my first attempt by *slightly* squishing the sleeve with pliers (just to hold the wire, I thought) and letting too much solder flow onto the blade part. No matter how hard I pushed the wires, the connectors refused to snap into place in the shells. Scraping off the excess solder didn't seem to help. I pushed so hard with pliers that the wire and insulation started to bulge, making the problem worse not better. I should have followed the instructions more carefully! Second time around after cutting off the first attempt, I just pushed the wire home in the connector sleeve, held the fitting vertically in a bench vice and carefully soldered into the sleeve part, with no attempt to crimp or squish it first. The wire fits quite snugly into the sleeve so that the soldered joint seems plenty strong enough, probably stronger than the Power Pole to Power Pole connections anyway. Time will tell! This time, the connectors easily pushed into the shells and snapped right into place as intended. Job done. 73 Gary ZL2iFB PS For other ZL builders: Jaycar Electronics sells 30A and bigger Power Pole clones for about NZ$5 a pair but the packets don't currently include the little pin that locks the red and black shells together. I guess you could superglue them instead. ______________________________________________________________ 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 |

Actually there is a plastic locking bar ("Blok-Lok") that has pins that fit through the holes in the mating connectors and keeps the connector housings in alignment as well as preventing pull-aparts. We use them quite a bit in our EmComm and vehicle installations. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ______________________________________________________________ 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 |

Hi Don,
That concern was addressed in the article: "It also has, in addition to a properly sized anvil/die, a forged round forming section that is ideal for fixing mistakes." A bad tool is a bad tool. I'm guessing you're like me, crimp and solder. A bit overboard, but does provide that warm fuzzy feeling. Check, double check and then recheck any critical and potentially dangerous connections. Cheers, Julius
