Captive wired test fixture
View Patent ↗A method for wiring a test fixture comprised of two parallel fixture plates wherein the wires are wired randomly from locations on one plate to locations on a second plate using a system of software algorithms and positioning apparatus to control the motion of one plate relative to the other to allow the wires to be passed directly through the hole locations to be wired together, while previously woven locations are allowed to slide in the hole in the fixture plate to allow reaching subsequent hole pair locations. After the fixture is wired, a termination is added to the wire end emerging from the hole in the fixture plates. The resultant assembly consists of contacts on one outer surface electrically connected to contacts on a second outer surface with all of the wiring sandwiched between the two fixture plates.
1. A wired test fixture comprising:
a probe plate having a plurality of holes;
an interface plate having a plurality of holes;
a plurality of wires extending through the holes in the probe plate and the holes in the interface plate;
one end of each wire attached to the probe plate by a probe contact positioned in the holes in the probe plate; and
an opposite end of each wire connected to the interface plate by a separate tapered barbed contact positioned in the holes of the interface plate.
2. The test fixture of claim 1 , further including a launch tube and a stylus for passing the plurality of wires through the holes in the probe plate and holes in the interface plate.
3. The test fixture of claim 1 , further comprising a laser positioned above the holes in the probe plate.
