As mentioned in another thread, a BNC connector failed me on a recent activation. I had attached it myself, and handled it carefully when in use. It showed no sign of damage, so I was curious to know what went wrong. Sorry, nothing dramatic, but I thought I’d share, and would welcome comments or advice.
Here it is, before I opened it up, showing two layers of heat shrink sleeving to give mechanical support. I have experienced tearing of the braid close to the crimp after much use, but not in this case:
Sleeving removed, and crimp sleeve filed through:
Actually, it was the centre conductor that had broken, right against the crimp:
The cable is RG58A/U, which has a stranded centre conductor.
So, what was the cause? What can I do to reduce the chances of this happening? The connectors are of good quality, designed for RG58A/U and the crimp tool has the correct dies. It almost has to be something I’ve done, or not done!
