TWINSET 1793 Posted April 23, 2015 I've started to get a bit obsessed with wiring, and one problem's always been servo leads I used to coil them up but they eventually slacken, so I bought the kit to shorten them from www.cpc.co.uk Tool; Multicomp HT-225D (CPC Part CN16614) Crimps; Multicomp 2226TG (CPC Part CN14576) Housing; Multicomp 2226A-03 (CPC part CN14556 ) The housing's not an exact version of a servo plug, it doesn't have chamfers on the underside, but not many of my receivers have chamfered apertures now anyway. It's also possible to get the old plug off without wrecking it, so replacement housings aren't always necessary. First step - Remove wires from housing Lift up the locking device with a thin blade - if it seems stuck, push the wires towards the end of the plug to disengage the lock from the crimp - they move forward about a millimetre Then cut the crimps off, and shorten the wires The wire needs stripping to match the crimp - about 3mm of insulation needs to come off A crimp in all its glory insert the crimp into the tool and compress it ever-so-slightly to form a round tunnel (this also traps the crimp in the tool and stops it falling out insert wire, you can feel when the insulation bottoms out against the section of the crimp that retains the exposed wire Squeeze handles to crimp the assembly, it should look like this afterwards Then slide it back into the housing The weapons 3 Share this post Link to post Share on other sites
Champ85 608 Posted April 24, 2015 Huh. I've always cut out a section of wire in the middle and soldered the ends back together and heat shrunk them to avoid playing with the connector. Your solution is Cadillac. 1 Share this post Link to post Share on other sites
WillyChang 1812 Posted April 24, 2015 if doing servos just cut the other end, resolder back to circuitboard Share this post Link to post Share on other sites
TWINSET 1793 Posted April 24, 2015 My soldering's not so great Willy - I think in a former life I was a shipyard welder 1 Share this post Link to post Share on other sites
WillyChang 1812 Posted April 24, 2015 At least the welder is a skilled craftsman...! I'm more like the scrapyarder with the oxy torch, breaking up oceanliners for scrap Seen the installs where they've changed all wires to same 1 colour!? hehe Resistance is Futile (or just darned waste of energy) Share this post Link to post Share on other sites
Cplus 94 Posted April 25, 2015 I cut the plugs and re crimp too. I also have a stash of new housings - the little retaining tabs break easy. Soldering is another valid option, but unless you are confident with circuit boards and have invested in the right gear (de soldering tools, correct shape/size tip - plus a good iron) there is a risk of burning the board and/or causing other joins to fail.

WillyChang 1812 Posted April 26, 2015 Ironically the first joint to fail is often the crimp so I usually solder the little wire into the crimp contact. Same with every other crimped join - just warm it up & flow a little solder in. Usually takes less time than waiting for iron to warmup; most time taken by extracting the pins out of their plug bodies. Share this post Link to post Share on other sites
Cplus 94 Posted April 26, 2015 Good crimpers make a massive difference. I find my crimps are stronger and less likely to fail than the factory ones. I do add a little solder sometimes as well though. Especially if it is a plug that gets removed often. Share this post Link to post Share on other sites
WillyChang 1812 Posted April 26, 2015 haha yeah... people around here seem to love pulling out wires by the cable not the plug Just had to bust out the solder station... nice tools always much nicer to work with. Dropped a torch last night and it stopped working, so decided to reflow all its joins... and since it was already open, extracted it's puny little LED and replaced it with a white 16,000mCd unit. Seems to have double the light now Share this post Link to post Share on other sites
