==>the soldered wires will just snap off of the pins from movement<==
Yes, that is obviously a problem...I just add a "pull wire" for that. But, as I mentioned, if you use the right angle connector, you can mount it direct to the PCB board. This makes it easy to grab for pulling, and will even help support a pull on the wires.
I'm sure you will be able to find a different connector that meets your needs; this one works well for me.
