I have been looking for some of the Cat5e RJ45 plugs to terminate a
couple of lan cables.
I bought some 2 part plugs, but they were too wide and wouldn't go into
a standard RJ45 socket. I then bought some more RJ45 plugs , not 2 part
tho', and they were the same, too wide for the socket.

The ones I bought were from Amazon, and they had good reviews and write
ups, but not from me!

Any ideas as to what's going on with the said plugs, and I am no loath
to buy any more in case they are the same.

Lan socket, cable tester, laptop and a netgear switch, where the plugs
would not fit in any of them

Sounds like you are trying to plug them into a socket that is not RJ45...

A RJ45 should be about 12mm wide, with 8 poles.

A usb type A plug will *just*` fit into an ethernet socket, but not
vice-versa , though I would expect someone who sets out to make up their
own cable to know the difference!

I had to make up some 10P10C serial cables for an emulex terminal server
a few years ago, slight confusion when you accidentally drag one of them
out of the spare cables box and wonder why it doesn't fit.

Can I just ask that some of my cables, a couple I made up myself, and a
couple I have bought,why they only light up led numbers 123 then 567.
Now I have just found that the 2 I bought don't work plugged directly
into my router lan socket then to my laptop.

If I remember right, a few years ago, the cables I made up myself, all
the lights blinked 1-8, and do work fine.

A 'basic' cable needs 1+2 and 3+6 as used in Cat3/5 and ideally with
each in twisted pairs and correctly polarised.

If I remember right, a few years ago, the cables I made up myself, all
the lights blinked 1-8, and do work fine.

That would be typical for Cat5e onwards with the same pinout as above
but also with 4+5 and 7+8.

All straight though cables should test out as 1-1, pins 1 to 8.

No it only indicates 6 wires. How those 6 wires are divided into
pairs is unknown from the information given.

Assumption that the tester is one of the cheap cyclic LED jobies and
the the LEDS 1 2 3 - 5 6 7 - only light up ( - means no light up) in
sequence and the same on the tester and remote unit.

As the RJ series only goes in even numbers of positions and we have a
number 7 the conector is either an 8 position or 10 position one. A
10 position would not fit a network cable tester so we have an 8
position one. The cables being tested are supposed to be network ones
so should be following T568A or T568B. Meaning that there are only
two working pairs 1/2 and 3/6. 4/5 and 7/8 each have one leg missing
so are not pairs.

Agreed, but see above.

My point was *if the interconnecting cable between the plugs has 8
wires, and that the wires for such network cables are wired in pairs,
then if there isn't a full compliment of connections available then
there 'must be something wrong'*. I wasn't actually commenting on
'pairs' at all.

But I agree, it sounds like there could be an issue with the tester
(contacts within) or more than one duff cable.

As I believe has been mentioned, you can easily plug a Type A USB plug
into an RJ45 socket and 'sometimes' the pins get bent, losing their
shape and so tension.

I have generally been able to straighten and re-tension the pins using
a couple of small flat-bladed screwdrivers and some quality fine
tweezers.

And / or one bent, they don't it back in the right places (little

Or it could also have been damaged electrically / just failed. ;-)

If the Ethernet port is on the mobo then you might find a new Mobo on
eBay pretty cheaply or it may even be on a 'remote' board (even
cheaper). Or you can use a USB Ethernet adaptor, if you just need

I had a look inside the rj45 socket using a small torch and it looks
like the the brown wire pin and the orange / white wire pin are right up
to the top of the back slot. The brown / wire wire pin looks like it is
flat down to the bottom of the back slot, and the rest of the wire pins
are all in a line just up from the bottom of the back slot.

Strange. 3 pairs?

Only two.

Except that 6 pins connected only indicates 3 pairs?

No it only indicates 6 wires. How those 6 wires are divided into
pairs is unknown from the information given.

Quite, but not in the spirit of the comment I was making.

Assumption that the tester is one of the cheap cyclic LED jobies and
the the LEDS 1 2 3 - 5 6 7 - only light up ( - means no light up) in
sequence and the same on the tester and remote unit.

Yup.

As the RJ series only goes in even numbers of positions and we have a
number 7 the conector is either an 8 position or 10 position one. A
10 position would not fit a network cable tester so we have an 8
position one.

Yup?

The cables being tested are supposed to be network ones
so should be following T568A or T568B. Meaning that there are only
two working pairs 1/2 and 3/6. 4/5 and 7/8 each have one leg missing
so are not pairs.

Agreed, but see above.

My point was *if the interconnecting cable between the plugs has 8
wires, and that the wires for such network cables are wired in pairs,
then if there isn't a full compliment of connections available then
there 'must be something wrong'*. I wasn't actually commenting on
'pairs' at all.

But I agree, it sounds like there could be an issue with the tester
(contacts within) or more than one duff cable.

I tend to think it is something to do with tester and I have ordered
another one, not the same tho'.

Worth noting that some of the intermediate level testers that are
capable of not only identifying that the right point to point
connections are made, but can also identify when split pairs have been
used, will often have a minimum length of cable they can reliably test
for this. On mine its about 0.5m

The new tester arrived and I tested 2 bought cables and one I made up
myself. They all tested fine with all 8 lights lighting up.

As a thought, are you sure you are dealing with an RJ45 / LAN socket
and not an RJ11 / Phone type socket?

Lan socket, cable tester, laptop and a netgear switch, where the plugs
would not fit in any of them

So its not a RJ45 plug then is it...


Methinks RobH is just playing with us.

Err, no I wasn't actually.
Anyway I have measured the width of a couple of RJ45 plugs, and the
standard ones I already have is 11mm across the width of the plug,
whereas the too wide ones are about 11.2mm or a bit more

I would first look inside the socket at the pins and check they
haven't been distorted / miss located.

As I believe has been mentioned, you can easily plug a Type A USB plug
into an RJ45 socket and 'sometimes' the pins get bent, losing their
shape and so tension.

I have generally been able to straighten and re-tension the pins using
a couple of small flat-bladed screwdrivers and some quality fine
tweezers.

And / or one bent, they don't it back in the right places (little
'bays' in the socket moulding).


I had a look inside the rj45 socket using a small torch and it looks
like the the brown wire pin and the orange / white wire pin are right up
to the top of the back slot. The brown / wire wire pin looks like it is
flat down to the bottom of the back slot, and the rest of the wire pins
are all in a line just up from the bottom of the back slot.

Once you have ascertained what is 'normal', you might be able to
'gently' ease each of the pins back in place.

The spec says 11.684mm

Could someone have inserted a 6pin plug instead of 8pin? That might
force the contacts out of line.

And Ive just measured a bunch of standard network cable plugs. All 11.6mm.

Once again you provide information only to confuse. You havent yet
provided a link to the ones that you bought that you say are too big (and
yet according to your measurements theyre too small).

I doubt that very much as it's only me that uses the laptop
