Faulty brother printer USB - fixing the USB type b connector?

[The Torrent]

Hi, anyone know how I can fix this connector?? Without completely taking it a part and resoldering?

It's broke. I don't see a way of fixing that. I would solder in a replacement if you really want to fix it. That is the safest way. USB B ports are fairly easy to solder as the contacts aren't that close together. 

 

You can see this digikey example. Double check to make sure it matches yours.

Do you know what type of USB port it is? I know it's USB type B female but does the one in the photo (attached to this post) look alright? There seems to be a lot of different types and none look like the one that was there originally.

Or you could get a USB cable  (take one from a cheap / old mouse you no longer use, or buy one here's example : https://www.digikey.com/en/products/detail/assmann-wsw-components/A-USB20AM-OE-100BE28/10408407  )  and just solder the data wires (green and white) to the circuit board. If it doesn't work, flip the two wires, solder white and green.

i thought about doing this. the only thing is.

 

There are 4 pins on the board? all 4 where connected to the usb b connector. which ones do i solder to?

 

Technically there is 5/6 because the metal sides of the connector where also fully soldered to the board

+5v (red)  , ground (black ) , data - (white) , data + (green) 

 

The data lines will be easy to figure out, they'll run very close together like this ===== to a chip.  

The ground goes to ground, probably the copper fill on the bottom of the circuit board , you can figure out with your multimeter in continuity mode put one probe on the negative of a capacitor or the ring where you screw down the circuit board  and the other probe on the through hole you think it's ground ... if you get continuity that's it. 

 

The circuit board may have holes for physical retention, rigidity, to hold the connector to board without stressing the pins ... those are usually connected to ground as well, or not connected to anything. 

 

Also there's 250 usb B connectors on Digikey : https://www.digikey.com/short/tw9hh981

Pick a few that seem to have the spacing between pins and the placement of pins and those retaining clips like yours and open the datasheet, and see those 4 pins and which is what - >90% chance brother didn't make things different just to piss everyone off.

 

For example second result in the link above seems close enough : https://www.digikey.com/en/products/detail/on-shore-technology-inc/USB-B1HSB6/2677744

 

The datasheet shows you the pins looking at the front of the connector :  http://www.on-shore.com/wp-content/uploads/USB-B1HSXX.pdf 

 

 

And it shows how it would be on the circuit board : 

 

 

 

and if you look on your circuit board, Brother was kind enough to even number the through holes with 1, 2,3, 4  - just outside the white frame : 

 

 

The order is standard,  1 is voltage (red), 2 is data-  (white) , 3 is data+ (green), 4 is ground (black)

i tried and failed.... my soldering prowess must not be the amount required for this

 

Thanks for all this, i will likely just wait for the internal connector now, might try again if i get impatient.
