+FarmerPotato Posted March 24, 2019 Share Posted March 24, 2019 (Posting in TI-99/4A because it's my home page) I had never used a crimping tool until now, only solder. But I'm making an arcade joystick console, and the buttons and stick (links to Ultimarc) have quick disconnect terminals. So I got a $10 crimping tool at Lowe's and made a wiring harness. (The buttons use 2.8mm quick disconnect terminals, which are not common. Don't forget to buy these when buying buttons! Fortunately I had a box from an estate sale.) So now for the 9-pin D-sub connector that plugs into the joystick port! I have only used solder-cup 9-pin connectors, but I picked up these at Fry's. (Fry's is a giant electronics store that is both a train wreck and a lifesaver at the same time.) 9 Pin Female Crimp Style D-Sub RS232 Female Contact Pins So how the heck do I crimp those contacts onto wire ends? My trial efforts are miserable. I need another tool. I found this video showing closed-barrel D-sub contacts. I'm not sure if the tool works for these Fry's open-barrel or Dupont contacts. This 4-indent, closed barrel pin crimping tool costs $50. (I saw the tool chained down in one video.) https://www.grainger.com/product/GREENLEE-COMMUNICATIONS-6-1-2-L-Crimper-4NHR5 I think I need the SN-28B ratchet tool used here. It's more reasonable for $22 I'm about to give up and just go buy solder-cup 9-pin D-sub. Advice? Before I throw any more money into a crimping tool? Will it just give me more grief?

+Ksarul Posted March 24, 2019 Share Posted March 24, 2019 The open barrel types I've used in the past had a pair of tabs that fold over the wire when you crimp (like the Dupont style connectors). I personally use the closed-barrel type for crimping when I need to do it. 1 Quote Link to comment Share on other sites More sharing options...
+FarmerPotato Posted March 28, 2019 Author Share Posted March 28, 2019 Well, I got the $11 crimping tool (for open barrel contacts) at Altex. No ratchet. It did the job, with extra hands. Amanda now has the amended title "Chief Sloth of Communications and Crimping." Unfortunately, Altex is like an electronics candy store, and I spent $40 on stuff I didn't necessarily need right away. So the cheap crimping tool sort of cost $50 anyway. 3 Quote Link to comment Share on other sites More sharing options...
Shift838 Posted March 28, 2019 Share Posted March 28, 2019 I hate the crimp type! I bought all the needed items to do it and after an hour I think I was only able to get 8 wires crimp successfully. It's all about lining the crimp connector in perfectly with the wire. There are tabs that get folded into the center of the wire. I finnaly said screw it and used a solder cup and was done in less than 5 minutes. 1 Quote Link to comment Share on other sites More sharing options...
