Re: JST crimping

 

¿ªÔÆÌåÓý

Hello Steve.

I actually just received a iCrimp from Amazon:


The jaws even the front thin one is more than 4mm so I had a bit of trouble loading that very short XH pin into the die.? I did make it work and the connection is good but I did have to use the front opening of the die.? Even then it was hard to get the pin positioned in a good place in the tool to make the crimp.? It did work but not the best way to do it.? Maybe I will get the hang of it one day.

I was crimping pins for a JST male header on the CalQRP W8BH LC meter.

Thank you.

I use these JST XH connectors in my projects. You need the proper crimping tool to do it right. The choice of crimping tool? and the correct position for your wire gauge ?is vital.?

A lot of the Chinese crimping tools do a poor job of crimping these connectors, I had to buy another tool after the first one with blue colored handle grips made very unreliable crimps. The second tool I purchased YEFYM model SN-2549S (red and blue with a silver colored crimp die) has been doing a great job.
I attached a picture of the second tool.
