Hi there - we are seeing an unfortunately high failure rate on the
wires going into our Harwin Datamate L-Tek connectors. We are using
Harwin M80-8881005 (http://www.harwin.com/catalogue/search/index.html?
familynum=M80-888&PartNumber=M80-8881005) connectors. It seems the
wires going into them are being bent fairly repeatedly right at the
crimp connection due to the lack of strain relief on the jacket of the
cable. This is causing huge problems for us, no big surprise!
Anyways - there isn't really a nice traditional way of providing
strain relief that I can see due to our space constraints. So what I'm
hoping to do is pot the end of the connector (the wire side) in some
sort of fairly soft material. Due to our low volume, instead of making
a mold I'd probably just wrap electrical tape around the top of the
connector and fill that in with some sort of rubbery material. Maybe
fill it up to about 4-5mm above the back of the connector. The idea is
that the potting will prevent the wires from bending right at the
crimp, and instead have a much larger bend radius.
Any thoughts on my predicament? Are there any good materials out there
for this application?
Thanks!
