Pressure-welding a Flat Cable to a MIL Socket
Use the following procedure to prepare the connecting cable by pressure-
welding a Flat Cable to an XG4M-2030-T (20-pin) or XG4M-4030-T (40-pin)
MIL Socket.
1,2,3... 1. Using a fine flat-bladed screwdriver, open the hooks at both ends of the
MIL Socket and separate the contact side and the cover side. There are
two latches at each end of the Socket (i.e., the contact side, and altogether
four laches). Release the bottom laches on both sides at the same time,
and then release the upper two. Do not attempt to release two latches on
one side without releasing the latches on the other side.
2. Insert the Flat Cable between the separated Socket sides, line it up with
the contacts, align the contact side with the cover side, and lock them in
place. Use an object such as a vise to firmly press them together until they
mesh with the latches.
