Looking for USB to JST cables

(1/2) > >>

tszaboo:
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.

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.

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 use this cheap and good™ one).

Two 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 hole

A lot of variations is possible, of course  :)

I had a look around 1688.com and found a seller of various types...

Here is USB A to JST XH
https://detail.1688.com/offer/624647879144.html?spm=a2615.7691456.autotrace-offerGeneral.13.191d3db2apLttb

They do lots of different "something to JST/Dupont/Other PCB Connector" type of cables actually...

Easiest way to buy from 1688 if you are not in China is to use superbuy.com (or other agent, but superbuy is my pick at the moment).

No, I may want to make (or have them make) a few hundred of these.

See above.

I'm not familiar with these websites. What should I know about them? Did you already write about your experience?
