Title: Trying to find a vintage Philips specific, test gear mains connector plug?
Post by: unknownparticle on September 25, 2022, 04:32:02 pm
Due to my inclination for collecting Philips test gear,  I have a problem!
The mains connector sockets Philips used on the back of their instruments through the 50's and 60's, was specific to them, at least I think so :-//

So, can anyone help identify it and confirm it is specific, or if not, what it is?  Then I need to find some, so would appreciate any help with that.

Image attached, in this case it's an RF sig gen.

It occurred to me that some might be interested to see the front panel so :-

It might help to add some measurements of the connector and the pin pitch/diameter.

Edit: If it's #31 in this link: https://www.plugsocketmuseum.nl/ApplConn_classic2.html (https://www.plugsocketmuseum.nl/ApplConn_classic2.html)

Then they state DIN 94941 (earthed) is the matching connector, see #28.

It is hard to judge the scale, but that looks a good candidate for a IEC connector conversion. Probably cheapest and safest route too.

There's more pictures with measurements, but I doubt "European Giant Pin" is the official name, here: http://madrona.ca/e/powerConn/index.html#euroGiantPin (http://madrona.ca/e/powerConn/index.html#euroGiantPin)

Yup, bullseye, thats it!!  Thanks very much, also for the plug and socket museum link, wasn't aware of it!!  So, now to find some plugs from somewhere!

I want to avoid that if possible, would really like to find some complete leads, or at least some plugs.  For some reason, old Philips test gear never seems to be found with their mains leads!

It looks like the ones used for electric irons or toasters. https://www.textilkabel-shop.de/Waffeleisenstecker-klassischer-Heissgeraetestecker (https://www.textilkabel-shop.de/Waffeleisenstecker-klassischer-Heissgeraetestecker). Distance mid-mid is 19mm, diameter is 6 mm. you should check this.
You will find a shop nearer to your location, too.

on the madrona site the inlet is for 3 wire, like your philips, the cable in the picture is only 2 wire, which you can't use.

I think that the measurement is necessary. From the picture, the size seems smaller compared to what RolandK mentions, but on the other hand it fits to description in socket museum.

In Czech republic it is quite common socket, since it had been used in Remos "table oven" and almost everyone had it at home. In comparison with irons there was no reason to replace them, so the spare parts are produced till today to keep even the oldest ones running (I have did small upgrade on mine ;) ). In Czech the connector is in 99% connected with word "remos" or "remoska".  You can buy new whole cable (https://www.elektro-materialy.cz/flexo-remoska-gumove-s-vypinacem-2m-250v-) or only socket (https://www.elektro-materialy.cz/vidlice-nastrckova-remos-s-vypinacem) or second hand, in case that you will not found one who has the cable at home and get is for free.

Just noticed something, those suggested plugs have an oval shape, or straight sides with radius-ed ends, the socket is rectangular! Damn! I thought we had it!

You have read the description of connector pictured in #31.  :-//

31 Appliance inlet with 6 mm pins, spaced at 19 mm suitable for DIN VDE 9409 and DIN 94941 earthed and not earthed appliance plugs (see nos. 1, 3, 5, 7 and 9 - 22).    {WN}
The manufacturer is unknown; the inlet has no logo, MPAD or certification marks.
Among others the Dutch company Philips has used these so-called "Giant pin European mains inlet sockets" in power supplies and other electrical devices in the 1960s (information given by Evert Liewes).

None of the referred to "suitable" connectors are rectangular, double check the dimensions of your connector and I'm sure if you asked, those with these could also check the size for you.  ;)

Unless stated otherwise, for each of the appliance connectors shown on this page applies:
(i) rating of 10A - 250V, and (ii) contacts are designed for 6 mm pins, with a spacing of 19 mm
