content: Hi. I'm designing a gadget, that would have a permanently attached USB cable. Having a micro (or similar) connector on it is not an option. So I saw that in (for example) computer mouses, they use a JST or similar connector on the PCB and they just have a cable assembly that goes on the board.I'm looking to source these cable assemblies. This design is not for for high performance/industrial, so something from alibaba/express is also fine. Did you ever come across these cables?Thanks.

content: Just thinking here - if it is a hobby project and you want a cable permanently attached, why not simply sodering the cable directly?Also I do not know what the project will be used, but whether you use a JST-like connector or solder it directly, it will not like stress on the cable an the connector/connection - i.e. if it is to put somewhere and not touch it then fine, but if it is something like a mouse where the cable will move all the time then it might break.

content: If you want a connector, JST or otherwise (Molex KK 256 is not too bulky either, for instance), it's not too difficult to assemble it. Preferably, you need a crimping tool (I usethischeap and good™ one).Quote from: simonlasnier on September 04, 2020, 09:23:37 amTwo simple ways to handle mechanical stress on the cable connection could be- make a hole at the edge of the PCB and use a plastic cable tie to attach the cable to the board- if a device has some enclosure, put a plastic cable tie on the cable inside the enclosure, so that it stops cable from being pulled out through the holeA lot of variations is possible, of course

What should I know about them? Did you already write about your experience?

content: Quote from: NANDBlog on September 04, 2020, 10:39:32 am1688.com is Chinese B2B marketplace, but really it's B2anybody since most places have no or very low MOQ.If you are not in China you really need to use an agent to buy for you (same agents that buy from Taobao can usually do from 1688), Superbuy is who I use currently, but other agents I use are Spreenow and CSSBuy.An agent purchases the goods for you and have them sent to their warehouse, then on-ship them to you. You pay first for the goods and domestic shipping, and then for international shipping once it's at the warehouse and ready to send to you. Most agents also charge some service fee as a percentage of the product and domestic shipping amount.Superbuy, Spreenow and CSSBuy all accept Paypal for payment.Good places for learning about Taobao/1688 and agents are...reddit /r/taobaoreddit /r/fashionreps (people who buy knock-off fashion stuff do a lot of taobao buying)4chan cgl (people who but cosplay stuff also do a lot of taobao buying)

content: Not that this is helpful, but...I end up building one-off USB thingies in plastic enclosures.Since the cable goes through the enclosure and a grommet I have to make up the end after the cable is fed through.I have a TNI-U brand TU-190-08 model crimper which works fine on the JST XH pins.Ok, this is not very helpful if you're making 100 devices.
