Method for producing a captive wired test fixture and fixture therefor
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 method for wiring a test fixture comprising:
positioning a first plate having a plurality of first wiring holes extending therethrough in a stationary position;
moving a second plate having a plurality of second wiring holes extending therethrough to axially align a second wiring hole with a first wiring hole;
passing a wire through the first hole and the second hole; and
terminating an end of the wire on the second plate.
2. The method of claim 1 , wherein the passing of a wire includes positioning a launch tube above the first hole and passing a stylus attached to the wire through the launch tube.
3. The method of claim 1 , wherein the passing of a wire includes positioning a laser above the first hole to illuminate the first hole and passing a stylus attached to the wire through the first and second holes.
4. The method of claim 1 , further including pressing a first contact attached to an end of the wire into the first hole.
5. The method of claim 4 , further comprising moving the second plate to a second wiring position and passing a wire through subsequently aligned holes in the first and second plates.
6. The method of claim 5 , further comprising repositioning the plates to a final position and pulling the slack from the wires between the plates.
7. The method of claim 1 , wherein terminating an end of the wire is by a barbed electrical contact.
8. The method of claim 1 , wherein the second plate is moved by a computer controlled positioner programmed to order progression of wiring to minimize wire flexure and entangling of the wires between the first and second plate.
