Making a crimp

[RandyVSP]

I have run into some crimp on plugs that have been gining me some trouble, thought I would share:

No idea on the maker, but my Ideal crimper, works almost all the time....but once in a while, I get a cable that fails, missing one pair.

The problem is the little shims between the plastic pins get mashed, and then cover part of the contact on the RJ45. After finding several of these, I found a solution was to simply slice the area with a knife, and the problem clears....

The plugs are bought from my supply, and no idea on maker, but it seems to happen when Im pushed for time...go figure...

Maybe this will help some others here....

Randy, is your crimper maybe getting worn? After a lot of use, they can start getting poor alignment to the pins.
Just a thought.

I used to have this problem when I first started putting plugs on. At the time i was using the ideal type crimper and 'no name' plugs from my supplier. It appeared that the tolerance was not what I would call tight. At some point I got frustrated with a few call backs for cable plugs, and upgraded to a $150 AMP ratcheting crimp tool and purchased AMP plugs (about twice the cost). I immediately noticed the difference in the quality and had almost no call backs on crimped on plugs.

Since then, we've gone to 100 mbs and Cat5 so rarely do I bother crimping plugs on. I can buy patch cables for less than I can make them, and 99% of the installations that we do now are standards compliant patch panel to workstation outlet, so we just don't crimp much anymore.

Good Luck!

It is only my opinion, based on my experience and education...I am always willing to learn, educate me!

The crimper is almost new, maybe made 100 crimps.....

I have found its the no name plugs, I found some AMP and they all worked good....

AMP Plugs require a specific type crimper or die for an Ideal frame.

Make sure that you do not have AMP and other RJ45 modules mixed together as the errors that you are having will occur.

Do you have the Ideal Part Number, ex. 30-560, which is a AMP RJ-45 die for an Ideal frame.

I would think this would be a good time to reconsider the practice of rolling your own as it were.

You really shouldn't be regularly making crimp connections in the field. The standards use to forbid this practice.

Are you making patch cords, or trying to save a few dollars by not using patch panels to terminate?

Crimping plugs on solid conductors is not a good idea, since it usually means the cables will be subject to frequent or periodic movement. Solid conductors are meant to be in the permanently installed portion, therefore not subject to movement.

Crimping a solid conductor can lead to early failure.
It only takes a couple service calls to wipe out any savings you may have realized from this practice.

Not to mention how it looks to a client when you start having failures.

Well, I have exceeded my $0.02 worth....
