Aincent B&K power cord info???

[Don Lancaster]

Some really, really old B&K sweep generators and such appear to use a
round three pin removable power cord.

It definitely does NOT match the ancient HP 3 pinners (which, amazingly,
remain available for Newark!) and I cannot seem to find any info on it.

It looks like an old tv "cheater cord" spacing, except for the third pin.

The pins themselves are apparently aluminum or some apparently
unsolderable alloy.

There is not enough room inside the case for a modern entry connector.

Workarounds or availability?

Find three solderable pins that will mate to the unit, stick them
through a piece of paper onto the pins, and sculpt a little connector
body out of epoxy putty.

You could do it with crimp pins, but you'd have to crimp the wires
on before you cement them into a connector, which might be a PITA.

Good Luck!

Hello Don,

The pins themselves are apparently aluminum or some apparently
unsolderable alloy.

My workaround in such cases is often to remove it and mount of a little
box over the opening. That box then holds a nice solid IEC connector or
something else that is popular and complies with code. While at it I
sometimes add proper fuses and toroids to muffle conducted EMI.

Don, have you asked Bruel & Kjaer? They have an office in Atlanta.
Can you retrofit an IEC connector?

I've got a ~1973 Systron Donner frequency counter (nixies!) that has a
3-pin cord. I don't know if it's the HP type you mention or the B&K
type. I know a picture is worth a thousand words, but the other half
borrowed the digital camera... if you want a picture, I can get one
tomorrow. Here goes:

The 3-pin connector on the cord is a rectangle with rounded corners,
about 25 mm x 13 mm. The hot and neutral sockets are centered on the
13 mm dimension, while the ground socket is about 3 mm off center. The
ground socket is centered on the 25 mm dimension while the hot and neutral
sockets are about 8 mm either side of the center. The sockets themselves
are about 3 mm ID. The metal doesn't extend all the way to the surface
but is recessed about 1.5 mm. Between the edge of the metal and the
surface is a paper? sleeve that looks like it extends over the body of
the socket. The ID and edge of all three paper sleeves are natural,
while the OD of the hot and neutral sleeves seems to be red. The OD of
the ground sleeve might be green. The number 8 and a logo that looks
like a spiral next to a straight line are molded into the face of the
connector. The cord is marked (among other things) "18-3 SVT 60C". The
other end has a normal 5-15P plug. The cord still has a small paper tag
on it marked "BELDEN C S.54 (CSA logo) CORD SET CORDON AMOVIBLE 7 AMP.
125 V. 875 W. LL30830 BELDEN C".

Workarounds or availability?

Would one of the three-round-pin connectors (IEC-60320-C5) used on some
newer laptop power supplies possibly fit? One problem is that I think
this connector uses two different size sockets.

Never mind... I just Googled up a picture of the HP type at
http://www.sphere.bc.ca/test/cables.html and that is exactly what I
have. Although you might ask Sphere about it; they seem to have
assorted parts for older test equipment.

The B&K name is also used by an american test equipment manufacturer
