Hello,

I was looking to buy some f plugs, coax to f type adaptors, couples,
etc. and see that they are available in nickel plated brass or zinc.
Is there any difference?

Google said zinc was softer and would wear but I'm not sure whether
they are pure zinc or an alloy; the latter might be more durable? For
domestic use where they are not going to be unplugged repeatedly, I
can't see this is an issue; is it?

Thanks,
Stephen.

In article <bv8rb9ta05qm9jng6...@4ax.com>,
I'd guess the zinc is zinc alloy which casts easily - Mazak or something -
and also breaks easily. But cheaper than brass. Unless there really is a
big difference in price which is critical I'd get the brass ones.

I would personally avoid the zinc ones in case there is corrosion on
the thread contact with the socket due to dissimilar metals. The brass
has got to be a better bet unless the cost is really critical.

My last lot came from Screwfix and seemed to be pretty good quality (a
couple of years ago). Read the reviews - I can't remember what it was
exactly, but there was something about the description not being accurate
and another sort was needed (for my purpose).

Brass it will be then. Thanks everyone.

BTW the costs are more or less the same for brass or zinc (the
difference is pennies), so no reason to choose on the basis of cost.

Thanks,
Stephen.

PS I was looking at the CPC web site. Why is it that an adaptor that
has an f socket on one end and a coax socket on the other end is only
25 pence but to go from an f socket to a coax plug is over a pound? I
expected the plug option would be more popular considering that tvs
and recorders require a plug input but I suppose people use the right
plug rather than use an adaptor.

What doesn't help is that there is not one name for the plugs (and
sockets) that are traditionally used for televisions. On cpc I have
seen uhf, coax, and pal all used as different words for the same
thing.

Thanks,
Stephen.

They were traditionally known as Belling-Lee connectors. Perhaps they
still exist and object to that name being used apart from genuine ones.

IMHO, they are one of the nastiest connectors around. Right up there with
SCART and DIN. ;-)

SCART is quite reliable provided you aren't stupid enough to buy gold
plated ones as they don't mix well with proper tin coated ones.
There are a lot of nasty ones about that don't use proper scart cable
(yes there is cable specifically made for scart).
A good quality scart cable will set you back a couple of quid.

Which DIN standard did you have in mind?

UHF, coax and PAL are all of course wrong. UHF being the frequency they
are sometimes used for (but I have one here for my VHF aerial...) coax
is the cable, and as for PAL - They have plugs that only support one
obsolete TV standard?

I used to have a Bush record-player that used Belling-Lee connectors for its Aux In and Out.

They're good for a couple of amps at mains as long as you remember that screen goes to Neutral.

Having used a few of the F plug to Belling socket in the last few days,
I have found that the F contact is very iffy unless you tighten them up
with a spanner. Personally I prefer Belling plugs with a soldered
connection, which IME gives less noise than the F plug/socket connection.

CPC sell different ranges of the same types of connectors, at different
prices. Not all connectors are available in all ranges.

I thought the criticisms are about the poor connection between the
cable and the plug? If you have one where you solder or screw the wire
to the plug, are they really that bad?

What is wrong with DIN? Are you meaning the five pins in a semicircle
din?

That's the 180deg one. I've always (since I was a teenybopper) used them
for my 12V vehicle aux sockets and plugs. Never had a problem really. I
use the 270deg ones for 24V.

The big problem with most of them, in my experience, is that they pull
out far too easily. Also, they wobble, so if the cable moves around a
bit they gradually inch their way out.

Again, this is just my experience, and I can't say I've used every
single variant. But I can say that I had a customer return on an
electronic widget I made which used DINs, for that very reason.

The locking version gets round that problem. They're still a very flimsy
connnector, though. Introduced partly to save on space, and partly to
protect the European equipment makers' monopoly, IIRC.

'Orrible things.

In article <ktssc917anptbma8f...@4ax.com>,
For a start, any connector made of a plastic which melts easily when
soldering (if it is a solder only connector) is junk as far as I'm
concerned. The Belling Lee fits into this too. The standard DIN plug also
falls apart easily. You can get better designed ones, though.

Other thing with DIN is the plating on the pins seems to corrode easily -
even in a normal domestic environment - over the years resulting in a poor
connection. That - and other reasons - is probably why they've fallen out
of favour these days.

The Touchel version - same pin spacing but lockable and made of decent
materials is ok. But in a different league, price wise.

I use RS ones and I don't have problems with soldering or anything else.
They are very expensive though.
