Multi socket extension lead - interesting failure mode

I have had a multi socket extension lead untouched behind the TV for I
guess 5 to 7 years connected to the TV, DVD, Video and Blue Ray. It was
a cheap unit, bought not off e-bay but from a high street store at the
bottom end of the market. I would never have really expected it to cope
with a 13A fan heater without getting hot but I thought it would be
fine for the use it was going to be put to (and indeed it has been up to
now).
Some tidying up following the final demise of the VHS Video player
forced me to disturb it.
I never expected the failure mode as shown in the linked photo.
https://www.dropbox.com/s/bb3l80251v7ivqj/IMG_20160919_164223098.jpg?dl=0
For info printed on the bottom was
BLS114
BS1363A
Total load not to exceed 13A
And a sticker which said 20070725 (Which I suspect is the date of
manufacture).

They are not supposed to fail by brittle fracture like that.

Are you sure it hasn't spent some time with a more aggressive load (like
a kettle or vacuum cleaner) plugged in? I'd be amazed if the load that
home entertainment kit presents could cause trouble unless you have 1kW
loudspeakers or something.

sunlight. Or that something very heavy was dropped on it in the past.
It is odd that both the plug and the socket have failed but there is no
evidence of heating of the brass. I have seen seriously abused ones with
discolouration and melting of the casing.
I reckon mechanical damage from a heavy falling object.

the TV. The plug has been in the wall and the extension on the floor.
It has, as someone else suggested gone brittle in exactly the way you
would expect of a thin supermarket carrier bag exposed to sunlight. It
probably doesn't show up on the photo but there are several other micro
cracks which I suspect would fall apart with very little further
provocation.

it more compact to photograph. If it was impact it would surely be the
top of the plug rather than the bottom section.
If it was impact it was during manufacture/distribution and certainly
didn't show up when I installed it.

Poundland *. I have found some products from that particular outlet
to be complete rubbish and would certainly not buy any safety-critical
item. I prefer to take electrical safety seriously.

It certainly looks like the poundland product. Just bad plastic I assume.

exactly happen to be that straight. These things are after all mass
produced.
Yup, crap cheese grade* plastic that doesn't take kindly to being stressed.
Possible the socket was forced apart by tension of the earth pin against
the plastic due to close clearance, and the plug top either fractured
when withdrawn from it's socket, or killed by an overtightened securing
screw.
* Ice cream carton plastic? Is it possible to do a burn test to identify it?

similar to yours IIRC) but brittle beyond measure. I wellied both
against the wall and they exploded like glass bottles. They were a few
years old and basically unused.

Not much help to me. However since I cannot see the picture, one assumes its
mechanical in some way. I had one fail recently where the connections to the
live and neutral cannot be sprung back enough to keep good contact to the
plugs.
Thus the slightest wiggle makes it spark or go off on that socket.
Now to me this seems like a design issue, but as you say its far too old
now to expect anybody to sort it. To get the bus bars out and away to do a
respring job would require melting plastic, so its a bin job. also the screw
into the live wire has been done up so tightly its sheared off half the top
of the screw, and so one would need a strong pair of mole grips to get it
out.
Made in England it says... Hmm.
Should have bought Chinese.

As they're both part of the same item, it's likely they're both made of
the same cheap/nasty plastic which has gone brittle for whatever reason.

Not on trailing sockets no, but I have experienced other hard plastic
objects going "crumbly" even when they've been kept out of the light.

I would say that is a manufacturing defect.
Something wrong with the plastic.
I have never seen a plug fail like that in forty years.
The old bakelite plugs might have failed that way but only with a very hard blow.

Well if anyone is still interested I have applied finger pressure to the
remains of the socket.
There is a short (60sec) video of the dismantling process using nothing
more than finger pressure, whilst one hand holds the camera....

They didn’t necessarily both fail simultaneously with it
hidden down the back of the media stack for years.

bought any with that shit plastic used.
While I haven't had any failures like that with plug boards,
what you lot call trailing sockets, I have with plastic boxes.

Neither have any of mine, but that doesn’t mean that some
weren't made with the wrong plastic that doesn’t last long.

Yeah, its clearly hopeless inadequate plastic.
It would be interesting to know if it was
always that bad but no way to know that now.

Unfortunately, many of these sockets seem to be made out of, well, cheap
crap.
I guess they work for a while, but it is obviously false economy if they
self destruct after a few years.
What worries me is how many of these dodgy things are lying in some
warehouse somewhere gently aging and will be sold on with very little life
left. I do not suppose anyone has the knowledge to tell the plastics aging
either.

Yes I think we have been here several times before. I guess it just depends
on the quality of the plastic. In my case one of the shutters appeared to
jam closed, but when I took it apart the finger over the earth that
operated the shutter had broken off and all the others were very brittle.

pushed a hole in the bottom with my finger! I was glad it was in the sink
at the time.
It must have been made from the same batch of floor sweepings, even
though it was a well known brand.
