network cable connectors

Hello,
I am trying to make a new network cable with the new connectors I have recently bought from Amazon
http://www.amazon.co.uk/RJ45-Ethernet-Cable-Connectors-Cat5e/dp/B0022AQVKE/ref=sr_1_3?ie=UTF8&s=electronics&qid=1266863772&sr=1-3
The cable I am using is
CAT 5E CABLE UTP SOLID 4 -PAIRS PX94 0710128
I am not sure whether its not the problem with the connectors not being correct as I am not able to push all the pins properly with the crimping tool to fit on the wiring
Please can someone advise how can I go about fixing this?
Thanks

hello dinhchung
thanks for your input but i dont understand a thing from the URL. i wanted to know if i am using correct connectors, as i am having problem in crimping it with the tool. please can someone advise if the cable and connectors above mentioned are good? if so, why i am unable to make the cable work?
thanks
That crimper should work just fine, Did you buy a cable tester too? They can help you determine which wires are not working. My tip is make sure before you put the wires into the RJ45 cut them at the top to make sure they are all the same length, put them into the jack, then make sure they go all the way to the end, you should be able to tell by looking at both the sides and top of the jack.
 
BTW: The string that is in the cable should have been cut off and should not be in the jack.

hi bcbigb
thanks for your input, i have checked all the existing cables which are now connected to differenct PCs on the network and they are all solid-core type and I believe they are connected to RJ45 jacks.
I am not sure why I cannot crimp, perhaps the tool gone broken or something which I am unable to find.
I was able to used old RJ45 connectors to crimp it on the same cable after buying these new sockets I am not able to crimp them I am also not sure whether the problem is with these new connectors?
please advise

Hey Charlie,

Sorry, I'm not sure I'm being clear. Just to make sure we agree on terminology: "RJ45 Jacks" refers to wall jacks (female-connections) vs "RJ45 connectors"  which are the "ends" on the cables themselves. Crimping is done with a crimping tool that forces the blades in the RJ45 connector through the wires, while on jacks (and punchdown blocks, and patch panels) you need to punch the connectors down.

The 1st problem we need to address: Above you say you have RJ45s being "crimped" on "wall jacks", which is incorrect (hence why I think we need to establish what exactly we're referring to in common terms). At least I've never seen wall jacks that you can crimp, given that it would likely be tremendously poorly designed and cramped in the very least. Punching down is the only way all wall jacks (at least modern ones in the last 10 years) are designed to connect to cables.

The 2nd problem: Beyond this, however, you cannot *crimp* the solid-core cable *at all*, anywhere. Solid core *must* be punched down as a crimper and connectors designed for crimping are not designed to deal with the thicker copper inside of solid-core cables.

What I think you were saying above is that you have RJ45 wall jacks, where you're taking the RJ45 modules out (the things that snap in to the face plate) and trying to connect the cable to those by punching it down.

I'm sorry if I sound like a broken record, but I'm just seeing a problem I've seen time and time again, so I need to be sure we check these facts before moving on or else we're ignoring the solutions right in front of us ;-)

Regards,
~BC
