Even PCBs are written in "Engrish" now

DANDER HIGH VOLTAGE
Ha! Like cat dander.

Yup..Wafer doesn't make any sense to me.

I think it may be a too literal translation of the shape of the connector.
Atleast they did polarise the footprint, seen so many people not bother with
that.

It's not even Wafer1..
What's the standard/com silkscreen for connectors?
CONN1 ?

Or CON1. I personally use CN1.

Ice cream context in the machine translator?
Con1 -> Cone -> Wafer

If there's any standard it's J1 ('jack'), and if you're calling out
connections in wiring harnesses the mating wire is P1 (plug, with
matching number).

In an ideal world, sure. In the real world, there are jack/plug moniker
mismatches all the time.

Sometimes you are a bit dopey.

If there is no "wafer 2" there does not need to be a "wafer 1", so
"wafer" is perfectly fine.

Just as, if there is not more then one transformer on an assembly, there
does not need to be any numerical designation made in referencing the
part. It can be referred to as merely "transformer", and will be
perfectly correct.

Normally, the connector/plug pair would be so designated, ie "J1" and
"P1" or other abbreviated terms such as that which you used, if the
connector were part of a remote attachment, as in the case of
interconnecting cables.

Since the connector/plug pair are being utilized as a "plug" for a
pre-fabricated "part", that being the "wafer", then the "wafer"
designator is all that is needed as long as all intended to ever build or
service it know what the moniker refers to.

Proprietary systems use this so that dopey repair dudes can deal with
their information overload easier... tee hee hee...

J for jack would be a guitar jack connector in Britain.

You cannot see the thermistor attached to that connector and plugged
into that socket marked "wafer"?
Click to expand...

Eh ?

It's a mains input connector. See the blue neutral wire and the required
double insulation (the black jacket).

That's the wafer you to connect wires to the PCB. ;-)

You guys are dopes. One can clearly see the thermistor in place in
that connector header. Can't see it? Then, you shouldn't even be in the
thread.

I apologize for the poor photo, here is a higher resolution photo of
the same PCB from a different angle (without the annoying popups):
http://www.divshare.com/img/4720478-d30
Even though there is a thermistor to the left of the connector, it is labelled
TH1 so I still don't understand what "wafer" is supposed to mean. This is the
main 120VAC power connector. The best explanation that I've heard so far is
that it's the "way fer" power to come in. :)

Is that on a monitor? Is that a degaussing coil?

"Way fer" magnetic distortion to go out...

NO. It's simply Asian English. This may help. I believe wafer simply means 'polarising
bar'.

Yes, it looks like you're right!

I must admit I've never heard of a wafer connector before, and based on the
number of replies here it looks like I'm not the only one :)

I'm going to have to include one of these in all my designs from now on, along
with some high voltage dander.

[email protected] (Tom) put finger to keyboard and composed:


I'm trying to understand the reason that an "S" is appended to
resistors, capacitors, and diodes, ie RS2, CS4, DS2.
Click to expand...

A purely inspired guess would be that these are 'safety rated' components.

RS2 looks like it could be a flameproof part, CS5 is likely an X-rated cap,
RS3 a high-voltage type (looks like the start-up R that needs 350V rating).

And you can see some 'CY' Y-type caps too on the second pic.

And then the theory falls down brilliantly on the secondary side !

As for WAFER, if you're looking for a typo on a QWERTY keyboard, then
possibilities include SAFER, WAGER, WATER, WAVER, WADER. However, I'll
wager it would be safer to keep water out of the power supply. I'd
also waver before touching the power connector, although wearing
rubber waders may afford some protection.

Google "wafer connector".
