For several years I have been using your JR connector, part number 1060, with your premium cable. They have been the best and easiest to make of the different brands I have tried. Recently I have had a number of packets in which several of the plastic housings would not let the metal connectors be pushed in - they go in a few mm but then hit a block of some sort. I cannot even force them in with pliers. It is like there is a tiny lip of plastic inside the housing that stops the metal connector from being pushed in. I take the next plastic housing from the packet and the metal pins go straight in with no problem, then the next plastic housing from the packet will not let the metal connector in, and so on. I have had to throw away a lot of the plastic housings.
Has any one else mentioned this problem? Can you suggest a solution to it?
