I have a "coin mechanism" from a fruit machine that I want to connect up. It has two plugs. One is 17 pins and one is 22 pins. The connections are the 2.54mm connectors and the instructions say I need a "17 Way Molex SIL 6471" connector.

17 pin socket

For the 22 pin plug I have the correct socket but don't have the tools or the crimps in order to add any more wires to it.

22 pin socket

Here is the correct socket for the 22 pin plug.

22 pin plug

And here is the connections from one on of the links inside the plug.

I did a LOT of Googling and also asked on here and managed to find these sockets from RS.

New socket

These sockets fit the slot after I snip off the small plastic 'keys' at the edges but I don't think I've bought the correct crimps.

These are the crimps I bought that I thought would be needed.

Crimp

But these crimps don't seem to suit the socket I've got.

Do you know what socket and terminals/crimps that I need to do this job properly?

A big thank you for any help you can give me and if you need more information please ask.

I would use the Amphenol 17 way MIN-PV series housing (part number 65039-020LF):

with the appropriate crimp connector depending on size (47711-001LF for 28-32awg, 47712-001LF for 22-26awg and 47713-001LF for 18-20awg): enter image description here

and if you really want to do the job properly, add the little polarising plug to the housing to match up with the missing pin (65307-001LF):

  • \$\begingroup\$ Thank you for your excellent answer. I don't suppose you would know whether it is possible to buy "pre-wired" crimps? I don't have the specific crimp tool needed and they are in the hundreds of pounds? Thanks again for your excellent clear description. It is much appreciated :) \$\endgroup\$

    \$\begingroup\$ I've soldered these terminals in the past. I suspect you could find a cheaper crimp tool to do the job but I've not seen pre-crimped wires. If you need a lot I'm sure there will be a company happy to make them. \$\endgroup\$

  • \$\begingroup\$ Thanks again. I only need 21 of these so I'll maybe enquire on a hobbyist forum to see if someone would make them up and send them me for a fee. Thanks again for all your help. :) \$\endgroup\$
