David,

the shorts are coming from under where the plastic grabs the cable jacket.  The wires under the jacket area get crushed together and push through the insulators per individual wire forming an electrical connection to several wires at once.  The connector will look perfect during inspection.  And fail to function, the tester will show numerous wires shorted.  This problem is less frequent with outdoor metal foil cables, but most frequently with indoor cables.  The outdoor cable has a thicker jacket offering slightly more protection to the wires is my theory.  My old radio shack crimpers works best (at least 20 years old), the new crimpers does it more often.  The third pair I got at the local hardware store(Ace) was so bad I threw them away (they would mangle the plug sometimes causing the gold contacts to push in sideways).  I been making my own LAN cables since twisted pair was invented, prior to most of you having been born, I just don't know where to get properly built tools and supplies anymore.  It seems to be all junk.  Digikey had what looked like the same junk I picked up at Ace, I had bought a pair from them decades ago that were super-nice (also cost several hundred$). Having to make cable-ends twice because the cheap junk stuff fails is not saving us money.

I need crimpers that crimp properly, no over-crimping and cable ends that fit properly.  I could use some tips on sizing the connectors to type of cable.  Right now I'm using ubiquity plugs for the ubiquiti tough cables (ground wire) and using CL0190 from Cable Creations (for indoor)(Cat 6 UTP) which seem to work better than some other cable ends I picked up with the tool I tossed in the garbage.

thanks,

jan

Completely agree.   Replacing the cutting blade is a big part of solving problems.   When it is dull, it pushes the wire ends down and doesn’t provide a clean cut. If we have problems with the ends, it is those longer ends/tails shorting together most often.    Plus they don’t fit into the jack as well.   A good, sharp blade on the correct crimping tool makes a big difference.

GAM - You need crimpers specific to the feed through connectors and the cutting blade needs to be replaced regularly.

The outside cable jacket needs to be under that tab - one of the issues I am trying to solve with different connectors.

    I bought a bag of through the connecter connectors once a long
    time ago.  I tried to cut the wires with a flush cutter wire
    dykes.  Too much wire still stuck out the end to plug into the
    jack.  Even tried sawing the end with a sharp pocket knife, even
    tried a razor blade, no such luck.  Barely enough to feel is too
    much, still won't fit.  Tossed the bag and bought a different style.

    Another problem I've had is old "tough " cable brand LAN cable. 
    Cables I made up 6 years ago the cable jacket has shrunk and
    pulled out of the connectors leaving as much as 3/4 inch between
    cable jacket end and connector.  Looks like a fitting put together
    by an amateur.  What brand is outdoor cable rated (with metal foil
    and ground wire) that the jacket material does not shrink?

    In addition, the crimper I'm using has a tendency to short the
    wires together where they fit under the jacket when the plastic
    edge comes into contact with the jacket (during crimping), this
    really sux.  Perfect looking fittings on both ends, one or both
    are shorted out.  The only fix I've found is to try to undo the
    twist of the wires below where the jack covers under where the
    plastic captures the cable.  Maybe I need a different kind of
    jacket capture design in the connectors I purchase?

            We have been using the connectors from TJ and they are
            working well.   The connectors we used in the past were

            Most all of them are gold plated to some degree, the
            highest is generally 50 micron/u of gold and some of the
            lowest is 3 micron or none. The connectors we have made
            are 50u, pass thru, shielded with the ground lug.

             Anyone that wants a sample just send me a name and address.
