A truss connector for releasably coupling ends of truss structures in a quick and uniform fashion. The connector connects trusses, end-to-end, by binding to their tubular truss members in spigot fashion with an arbor, traveling nut and expandable collet assembly and by binding to the truss gusset plates in a directly fastened, mated plate assembly.

What is claimed is: 1. A truss connector comprising: at least one mating surface; means for fastening the at least one mating surface to gusset plates found at the ends of trusses; and inserting members extending from the at least one mating surface, the inserting members for inserting into ends of truss members, wherein the inserting members comprise: screws; arbors along the screws; collets along the screws, wherein the collets are adapted to wedge against the arbors; and traveling nuts along the screws, wherein travel of the traveling nuts axially along the screws causes the collets to wedge against the arbors and that wedging action causes the collets to radially expand and bind against the interior walls of the truss members. 2. The truss connector of claim 1, further comprising spacers that join multiple said mating surfaces in separate planes. 3. The truss connector of claim 1, wherein said fastening means comprises at least one bolt and nut assembly. 4. The truss connector of claim 1, further comprising retaining parts for preventing said traveling nuts from traveling off of said screws. 5. The truss connector of claim 1, wherein said screws are differential screws. 6. The truss connector of claim 1, further comprising actuation means for moving said traveling nuts axially along said screws. 7. The truss connector of claim 6, further comprising a weatherproof housing inside which said actuation means is disposed. 8. The truss connector of claim 6, wherein said actuation means comprises: a drive gear; idler gears rotatably driven by the drive gear; and screw gears rotatably driven by the idler gears, wherein the screw gears are fixedly mounted on said screws, wherein rotation of the drive gear in one direction causes the traveling nut along each screw to move toward the arbor along that screw, and rotation of the drive gear in the opposite direction causes those traveling nuts to move away from those arbors. 9. The truss connector of claim 8, wherein at least one of said drive and idler gears is spoked, and wherein a stopping member may be inserted between spokes of the at least one spoked gear to prevent further gear rotation. 10. The truss connector of claim 6, wherein said actuation means comprises: a drive gear; and screw gears rotatably driven by the drive gear, wherein the screw gears are fixedly mounted on said screws, wherein rotation of the drive gear in one direction causes the traveling nut along each screw to move toward the arbor along that screw, and rotation of the drive gear in the opposite direction causes those traveling nuts to move away from those arbors. 11. The truss connector of claim 10, wherein said drive gear is spoked and wherein a stopping member may be inserted between spokes of said drive gear to prevent further gear rotation. 12. A truss connector comprising: at least one mating surface; means for fastening the at least one mating surface to gusset plates found at the ends of trusses; radially expandable inserting members extending from the at least one mating surface, the inserting members for inserting into ends of truss members; and actuation means for causing the inserting members to radially expand and bind against interior walls of truss members. 13. The truss connector of claim 12, further comprising spacers that join multiple said mating surfaces in separate planes. 14. The truss connector of claim 12, wherein said fastening means comprises at least one bolt and nut assembly. 15. The truss connector of claim 12, wherein said actuation means comprises: a drive gear; idler gears rotatably driven by the drive gear; and screw gears rotatably driven by the idler gears, wherein rotation of the drive gear in one direction causes said inserting members to radially expand. 16. The truss connector of claim 15, wherein at least one of said drive and idler gears is spoked, and wherein a stopping member may be inserted between spokes of the at least one spoked gear to prevent further gear rotation. 17. The truss connector of claim 12, wherein said actuation means comprises: a drive gear; and screw gears rotatably driven by the drive gear, wherein rotation of the drive gear in one direction causes said inserting members to radially expand. 18. The truss connector of claim 17, wherein said drive gear is spoked and wherein a stopping member may be inserted between spokes of said drive gear to prevent further gear rotation.
