identifying a crimp terminal

I usually have more luck than I'm experiencing at the moment identifying and sourcing crimp terminals, but this pair has me stumped.

I've found them both available in bulk from Chinese suppliers but I really don't want to buy 50,000 of each when I only want 4 of each!

They are -
Male terminal
and
Female terminal
( the latter is a mirror image - probably an image rotation issue ).

The blade has a width of 4.8mm.

They are found fitted to Fiat group cars ( but not necessarily to them exclusively as I can't see Chinese manufacturers tooling for these terminals just for Fiat! ) from the early/mid 1990s and wouldn't have been sourced at that time from China as all the other connectors on the car are branded AMP ( TE ), PED ( Delphi ), Burndy ( FCI then Delphi ).

There's not much help looking for a stamp on the terminals. All they have is a stamped arrow.

The housing for the female connector has 'RKG' moulded into it, nothing on the male side.

I've been through Mouser, Element24 ( Farnell ) and Radio Spares catalogues without success although that doesn't necessarily mean they aren't there somewhere.

Does anyone have any idea who the original manufacturer and maybe part numbers would have been for these terminals? I've not had a lot of luck identifying 'RKG' either.

Thanks in advance.

They're definitely in RS look for power connectors.

That's the female, can't seem to find the male though.
Pop in to your local RS component store or Google Tycho Electronics.

Looks like 175090-1 .

A couple of the dimensions differ from the TE tech drawing but it is probably of no consequence.

Unfortunately 175090-1 is not listed by RS or Farnell! But I'm sure I can find it somewhere now I have a part number.

I'm not so concerned with the male half as I can, as a last resort, purchase the a generic connector with tails fitted ( but I'd prefer to use the proper wire colours ).

Anyway, many thanks for your help. It's very much appreciated.

Try also Armour Auto UK that size is a standard speaker connector (+) at least for the male.
If you're near an RS depot, ask for the quoted sample then ask the sales assistant if he/she has the male version.

Just been reading your OP again. Think again I was just looking at a TE relay, made in China! Also TE(Tycho) own AMP.
Bosch; Tycho now have the manufacturing rights and can you guess where they're made?

Are the terminals to be fitted into existing connector bodies? Could the terminals needing replacement be substituted with the larger size(6mm or so) and a mating set of connector halves/housings be used?
Have you searched forums pertaining to the vehicle/brand in question? Perhaps someone has that section of wiring harness available.

Funnily enough, it is the speaker system I'm working on!

I'll check out Armour Auto and RS ( I have one not too far away, so next time I'm passing ... ).

The housings are too small to substitute 6mm.

The option of getting the wiring from a car being broken is a possibility. If I can't use new, then I shall do that although it would be a shame to not use the lengths of correctly coloured wires I've already bought!

Many thanks to you both. I'll report back later on what I've done.

It might even be easier to go into say Maplin in the UK, get multi way connector blocks of proprietary male and female connectors of a small size to replace your existing connectors.

That would certainly be the easy way.

However, I do have a self imposed rule that all work on the car has to look like it was put there by the factory.

This has been the case for all the work done so far which includes retro fitting climate control A/C and numerous other projects. Where I've used new connectors, they are of the type the factory used. Someone would need to know the exact model year of the car intimately to realise that this wiring has been added. All wiring is also of the correct colour (main and tracer) and, where possible, conductor size (sq mm). The latter isn't always possible owing to availability of small conductor wire in all main/trace colour combinations so I have had to go for the next size conductor up in some circumstances.

Just my little foible. It can cause me major grief especially finding some of the Burndy (FCI/Delphi) crimp terminals. But worth it in the end for my satisfaction.

Yes, just like when I do an install on German cars I use Tessa fabric tape, the wiring has to look original so I know exactly what you mean you OCD fool
No offence meant just been a very long day!

In the end it was easiest in this instance to get the wires cut from a car being broken.

So a nice chap cut out a couple of metres of wiring from his car and stuck them in the mail for me. I was also able to get some of the correct clips that hold/guide the wiring to it's destination ( although I'm not sure if I really need them at this stage ).

I'm all set now to integrate this wiring into the car.

Many thanks for the help.
