All good ideas, I have looked into them, but I was trying to do this as non-invasive as possible.
I was tasked to implement a solution for engaging two mass interconnect modules together that don't have a positive locking mechanism by sliding the fixture into the test station and fixing it into place. As long as the two interconnects make a connection and it is fixed into place, it was OK. So I developed a sliding mechanism the will allow different size fixtures (with the same interconnect modules) to be placed on a sliding platform with two different foot patterns (large or small fixtures). This is locked in place by using two guide carriages with locking levers (from McMaster). Now they want a "latch" to make sure this sliding platform fully engages the two mass interconnect modules.
Attached is the full slide interface.
The blue plate slides and the green plate is where the interface goes bolted on.
The second file are the two mass interconnect modules we are using.
I was trying to avoid putting anything on the surface of the sliding platform but I might have to throw that out the window, unless there's something that might fit between the two metal plates (grey and blue), which is roughly .9 inches.
