PRC EC5 Assembly Punch

AC-EC5P
Unique tool makes it easy to assemble EC5 connectors
$7.99

The EC5 is a great connector, but assembling them can be frustrating at best and dangerous at worst. This unique tool solves those problems for good.

Designed from the ground up in house here at ProgressiveRC, our EC5 Assembly Punch makes it a breeze to insert the EC5 bullets into their housing. Once the connector is soldered and ready to be popped into the housing, simply align the semi-circular lip on the end of the connector - the punch will cover over 180° of the bullet's edge, allowing you to apply even pressure safely and easily. Then it's just a matter of giving it a light tap with a hammer, or even pressing it in by hand!

Precisely machined from stainless steel, this tool is ready to put in a lifetime of hard work, and is proudly made in the USA.

Great tool easiest it's ever been

Not as good as I expected - but glad I bought it

The tool has a very thin half-moon bearing edge to punch the bullet into the plastic case. If it's not lined up just right it's easy to slip off and crush the soldered back side of the bullet. The first connector wasn't too bad but it took a few very hard hits with a hammer to get it to seat into the plastic case on my second connector. I had to pound much harder than I was comfortable with in the tight space required. Their tech support suggested plugging the male and female plastic cases into each other for a more sturdy assembly. I would suggest holding the plastic case in some kind of jig/vise. It's really hard to keep it from tipping while you're holding the tool and hammer with both hands. The tool should be longer so you have more space to hold it so you don't pound your fingers. Maybe even a driver that you just push in with your hands instead of having to pound it in. Next time I may actually try chucking it up in a drill press with the power off. Just use the press part to press it in. Use a vise to clamp it on the drill press table. I searched the internet for tips and some people suggested pounding it in right after soldering so the "slightly hot" bullet slides into the plastic housing easier. The heat would slightly soften the plastic during insertion then harden after it cools off. Obviously not soldering iron hot, just 100-150F. I also thought of using rubbing alcohol to lube the two mating surfaces. Then it would dry in seconds.

good product

good product, but you need to file the sides, because it cuts the jacket of the cable

A good idea, in theory.

In theory this punch should work. But in practical use if your solder joint doesn’t leave a clean ledge for the punch to engage with it simply does not work. I ended up grabbing the connector with a pair of needle nose vice grip pliers and tapping it with a hammer to drive the connector into the housing. That worked much better than the punch.
