What type/size Connector?


Recommended Posts

Hello, i have one of the first batch of K90's produced (i was a pre-order) and over the years the cable has taken a beating. it now has a short about half an inch past the opening in the back of the keyboard. moving the cable causes the keyboard to turn on and off.

 

well instead of throwing it away i would like to build it a new cable and maybe make it detachable like it should have been in the first place.

 

anyways i would like to keep the broken stock cable just so i have it if i ever need dimensions from it in the future. in the mean time i need to know what type/size of connector this is. i have figured out its a 5 pin jst but i havent found any 11-12mm 5 pin jst as my cheap tape measure says it is.

 

so would anybody know what the exact measurements are for this connector so i can put my keyboard back into use?

Unfortunately we are unable to distribute internal specifications for our productions due to liability and security concerns. We sincerely apologize for the inconvenience.

 

that sounds familiar... oh wait you used the same bs response that apple is giving to congress every time there is a right to repair bill hearing. unfortunately that means i will no longer be purchasing or recommending your products and when my current products wear out they will be replaced by products from another company.

eeeeh.. that's a bit different.. you can repair it. It's just that with any OEM, assembly BOM is confidential.

 

You can go to Mouser or Farnell and find these types of connectors. they are not exactly hard to find.

Your KB is out of warranty, you can do as you please with it.

 

If you don't want to lose time looking for a connector, getting the correct pins, and the very expensive crimping tool, you can just cut the damaged section, strip the wires, slide some heat shrink tube on each wire, solder them color to color, and shrink the insulation.

it's a quick fix really :)

 

Edit : I don't know how it's all assembled but another way you could fix it is to solder the wires directly to the PCB, getting rid of the connector and mating PCB pins altogether.

i can go the solder route with the connector in the picture, but on the 2nd connector which is on the back of the circuit board for the keyboard itself i cannot solder it as its too close to multiple plastic bits with copper circuitry in them.

 

also i dont want a bom or anything like that just a hint as to which size connector i need if jst is in fact the proper type. i have found pre-terminated 5pin jst connectors online, which i was planning on doing the cable splicing fix with, i just need to know if my tape measure is accurate/which size i need.

 

between all the function/home/esc/macro keys being membrane, the firmware being set to software macro key presses, and now this cable issue this is closing in on worst keyboard purchase i've ever made. only keyboard that has been a bigger waste of money is the saitek eclipse i bought from walmart in the early 00's.
