Uncrimping a crimp. Tips? Ideas? suggestions? See pics. Thanks everyone

ok, tried using my old thread but no one has viewed really.
So, Im making a new thread and dedicated to this topic.

I have the Neo 29 pins I needed, I have pulled them from a connector I got from someone and my main debate is this, I have pulled one of the pins ( see bent to hell in pics LOL) and cut the wire free (at insulated crimp point) Was easy. A issue I have found though is see the bare copper crimp point.
It's a rectangle and seems to be one SOLID piece and not two fins like the back side.
(see picture with screw driver pointing to location). I had tried to pull a few strands at a time, even one thread at a time. While this metal crimp point it pretty solid, the over all piece is still bendable. And I am trying to keep the shape so it will fit properly into the plug.

Suggestions and tips anyone have?

I am more than ok Using the used connector, I just need to figure out how in the hell to get this exposed wire out and be able to put the new ones in solder and crimp again lol.

As for the bent to hell one, I got it out once, fluke thing and then couldn't figure out how to pop it out again. after mangling the test dummy then Reshaping it i carefully inspected and figured out how I did it and what the EXACT point was to release, finishing nail ended up PERFECT to do it!!

I reuse those types a lot. The two sides fold over, in, and down like the letter "m". If you look at the rear wire gripper, it's exactly the same, only smaller and tighter.

To open, take an xacto knife and wedge it in between the "cheeks" and work it in and and side-to-side to spread the curved pieces apart. With a little work, the gap will open large enough to allow the wire to release. With the wire removed, take a tiny flathead and work from the inside the crimp to uncurl the foldovers a bit. Don't open it any further than needed to get your new wire in.

To reinstall, insert wire and gently squeeze the cheeks back together from the sides with a pair of needlenose pliers. Once they are touching, work from each side squeezing at about a 45° angle to curl the cheeks down into the wire. Every so often squeeze from the sides to close the width and the top to work the curls into the wire. Work slow and easy because if you crush it, you're not likely to get it open again.

It's a pita, but once you get the hang of it, it's not so bad.

wow..

So there is two pieces ? suckers must be flipping tight!!!!
Ill give this a shot.. Anything other than a xacto knife recomended?
Seems soooo tight I picture a xacto breaking pretty easily on this sucker..

small jewellers flat blade screwwie; doesnt matter if you bend or break them a they are dirt cheap
 
You're mostly using it as a wedge to release the wire, but sometimes it does break. I have one with about 1/4" snapped off the tip and it has lasted a while since then. One the wire is out I use a tiny flat blade like a jewelers screwdriver.
 
today.

Today ill give this a shot,
I will use my chewed bent to hell one as my test dummy.
will post results.. Cause I need to get this sucker done already.
boards sitting pending testing.. LOL

Thank you!

Wow this was a TIGHT sucker!
I ended up tapping with a push pin and was able to open a little and then a screw driver to pull one side up. other side was very very tightly done, wasn't able to undo but the wire connection is a two lead. so I was able to twist and crimp down again!!

Pics will come in a bit..
Now having issues getting it in the Jamma side..
LOL
Thank you though!

Can I ask...

how do you get these out of the harness/plug? This has been kicking my *ss and making my do some stupid wire rigging..

Also, I can't seem to find these - does anyone sell a "starter" kit?

I will be following these responses - great topic.

Thanks,
Chris
 
I know i know!

LOL..
I can say I know on this one.
first time was a fluke!
2nd time was careful inspection and inspection.
I used a finishing type nail.
If you look on the one side (LOOKING FROM BEHIND!)
you will see a small ridge/ramp in the middle!, you want to slowly push
a finishing nail or something similar up the ramp and along the middle of it.
it, you may have to wiggle slightly to push the ramp down a bit and pull out.

it will take a little time and REALLY good light!!
I am not kidding when I say

IS A AWESOME WORK LIGHT..
Great bright LED and has a hell of a white color too it.
I also used it to take up close pictures of stuff, you can avoid flash washout.

anyhow back to the point.
careful looking you will see the spot.
and a gentle hand but not to gentle..
THESE PINS ARE A PAIN TO REOPEN!!
but I am not having my issue on the jamma side..

also

Are you running a NEO 29 or similar inport?
how many of these pins are you looking for ?
the ones in the picture are the BIGGER ones..
I have seen some used on SEGA etc that are about 1/2 the size..
I haven't found a starter kit, just lucky as hell Matsu is close and
he had one..

Hey Krusher...

I am new to working on these arcade cabinets and happened to get 4 at once. I have been reading, posting, and watching you tube videos for the last few weeks.

Each cabinet has had its own share of issues or things I wanted to do. Everything from replacing buttons, tracing and replacing bad wires....

The most memorable was getting the sh*t shocked out of me trying to figure out why one of the cabs died...and trying all kinds of creative fixes....turned out the 2 "kill" switches had knobs which needed to be pulled OUT. I wonder how many "dead" machines have really been the result of not knowing this!!!

I have set 2 of them up as jamma multigames - one a 60 in 1 vertical and another as a 1315 in 1 horizontal. People before me did some interesting things with the harnesses - cutting wires - running and splicing all over the place...

Sorry for the long post, but seeing you have broken the 1000 mark for posts and asked this question... I feel pretty good about what I have learned so far and will keep posting when I can't find an answer through the search function.....

PS - does anyone have any ideas about where to get a set of these connectors - also, maybe some stick-ons mapped to each terminal on these harnesses? I made a "template" from a business card...but it is still a pain to try to match them up.

Thanks again! The KLOV forum is awesome!

PSS - anyone have t-shirts or caps with KLOV or something arcadzy?

pics of JST japan connector for neo 29

ok, well it sure as hell isnt pretty i couldnt get both side uncrimped.
so i did what i could and secured it as well as I could. i trust it and tugged.
so I crimped onto insulation on 2nd crimp and put it in place..
Now the fight on the jamma side..
