Many many thanks all much appreciated

 

Thanks for so much help

I bought the male and female parts they look identical, BUT how small is the difference as the male will n ot fit inside

Problem is that the battery box gives no size, it is almost as the "pin" in the female one is a millionth !!! of a mm too large, advice again please

This electronics isn't simple

 

There are two different sizes of center pin. One is 2.1 mm the other is 2.5 mm Both types of connector have the same outside diameter of 5.5 mm. You seem to have a 2.1 mm plug and a 2.5 mm socket. Here is a link to more information on this style of connector.

Thanks appreciated, annoying when you buy one thing and they don't say, thanks again

 

I consider the power connector soldered to and supported by those solder connections to be a very cheap and inferior arrangement.The reason is that bumpng and wiggling the plug leads to the connections of the soldered portions breaking. FAR more reliable is the incoming power connector that uses jam nuts to hold it in place., and wire leads for the connections to the PC board.

You would be wrong. Soldered correctly to the PCB, they are very strong (and industry standard). And for the record I have thousands of commercial devices in daily use, with said connections over a decade with zero failure.

Amazon and its sellers know nothing about electronic parts. You should buy electronic parts from a real local electronic parts distributor.

https://uk.rs-online.com/web/ I know them by reputation, I am in America. Many people I know use them, I don't know about pricing. They offer a very useful app called "Designspark".

 

I believe DigiKey is available in the UK?

 

On laptop and similar computers with a power plug out the back or side one or two bumps against that plug and the very small solder connections crack. The a BIT more use and suddenly there is no longer enough connection to charge the battery. THAT is the situation that I have seen. perhaps some styles of the power connector have an adequate steel strap to secure them to the PCB, those three computers did not. Thus my argument that an additional 50 cents pent in an $800 computer would be the difference between good quality and cheap junk.
Certainly the solder on connectors assemble much faster and go into the cases faster and last mmany weeks beyond the warranty, but for that money they should last a few years.
