Hey all.

can anyone please suggest ways to pull out the white coloured jumper (in the attached image) from the PCB board?

it seems hard to pull it, so wondering if there are any latch/locking involved.

thanks.

My first thought was that maybe it is soldered into the board. After a longer look and seeing the other jumper looped through the first and looking at how the two are wired I believe they for changing between 115V and 230V input voltages to a transformer. That being the case it wouldn't make sense for it to need unsoldering.

All I can suggest is to spray some penetrating lubricant down where each wire goes. Give a while to its job then see if you can wiggle it free.

 

Do you need to replace it sometime in the future? If not, you can just cut all of the wires at the top of their loops, otherwise I refer you back to Albert Hall in post #2

 

they look like the power connectors used on older disc drives in pcs

can be a pain to pull apart , but it should just "pull up" and split apart . just don't pull the wires , and a pair of pliers might be needed with a gentle wiggle ..

but streight up, if you pull at too much h of an angl , the pcb sicket will be ripped out !

yep I hate them,,,

If there are no locking tabs on the plug that isn't plugged in, it's just friction fit. It looks like there's room for a small flat blade screwdriver on the right side to start prying it out. Otherwise, use pliers to rock it back and forth. Or use the unconnected plug and its wire loop to pull out the other plug.

 

Use a pair of slip joint pliers on the white plastic housing and pull straight up.

 

use the force Luke...!

 

I see no catches or releases that need to be depressed. Chances are good that the plug body is not truly a plug body but rather a wired header that is soldered into the PCB. Pulling it out forcefully may result in damaging the through holes and any surface traces.

It's been my experience with through hole components such as a resistor or other leaded devices that it can take up to 114 pounds of force to break a well made solder joint. More often than not the leads break long before the joint fails.

If there's reason for removing the connections, please elaborate. If they're interfacing between two boards, what do each board do? What happens if you just cut the wires? Of course that would be a semi-permanent solution, one that would be difficult to go back and fix.

 

my reckoning is you have these

 

and they ARE hard to remove... it takes some pulling.

 

i changed color of the socket to green, this is part soldered to PCB.
white part is plug. grip it hard and pull.

 

besides... the other plug is tethered to one that is in the socket. you can look at the 'business part' of it and see what it looks like.

 

Thanks all! I removed it using a small flat screwdriver by lifting one of the sides and pulling it off just like @dl324 suggested. This has been of great help!

thanks for getting back to the forum, well done
