Strange patch panel connectors

["ihatetripe" <ihatetripe@xxxxxxx>]

Hi everyone!

Newbie here. I was told in the Kat5 group that some of you wisened
group members here may know the answer to my question. I am currently
installing a patch panel (bought from e-bay) and I cant work out how
to fit the Cat5 cabling into it. The cheapo punch down tool I have
wont fit. A picture of the sockets is here

Here is how I am currently trying to doing it.

Strip off the sheath to of the cat5 cable.
Split the wires.
The module is in 2 parts a top plastic part where I lay the cables
into the colour coded slots, and the bottom part which has the metal
parts the individual wires are pushed into and contact made, and the
main socket.
The problem I am having is pushing down the top part onto the bottom.
I have managed to finish 1, but by checking with a continuity tester,
one of the wires has not been seated properly. I cannot pull apart
the 2 to remedy this! I am having to use serious force in pushing the
top part onto the bottom.

Does anyone know of any tricks to doing this?

Thanks in advance for any replies!

James
