Even PCBs are written in "Engrish" now

Ugghh..annoying pop ups on that link..

DANDER HIGH VOLTAGE Ha! Like cat dander.

Yup..Wafer doesn't make any sense to me. It's not even Wafer1.. What's the standard/com silkscreen for connectors? CONN1 ?

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.

Or CON1. I personally use CN1.

Graham

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).

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

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

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

My favourite is one I found in an old guitar pedal. There was a drawing of the 9 volt battery and its connector, and the helpful text "connect battery to battersnap"

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...

For the most happiness times in Engrish, pleasing to be moved most forward into

Isn't it the way fer power to come in? or else the way fer it to go out? Probably they just omitted the apostrophe from the contracted form wa'fer.

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

Graham

Eh ?

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

Graham

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.

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

Have gnu, will travel.

I apologize for the poor photo, here is a higher resolution photo of the same PCB from a different angle (without the annoying popups):

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'.

Graham

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.
